The replacement cruisers


Painting of the Karlsruhe in Scapa Flow

A new, unnamed class was programmed in 1913 already to replaced the Wiesbaden class. They were an incremental step in design, larger, and four cruisers were started as WWI broke out, SMS Königsberg, Karlsruhe, Emden, Nürnberg, soon taking named of recently lost cruisers, and completed in 1916-17. For that late entry into service they saw limited action in WWI. Apart SMS Karlsruhe (ii) scuttled in Scapa Flow with the rest of the fleet in 1919, the other three were given as war prize, one to France (Metz, used until 1936), another (also scuttled) used by France as a target ship until 1926 and Nürnberg, also scuttled, sunk as target in 1922. The follwoing Cöln (ii) class was the most ambitious with ten ships ordered, and again, an incremental evolution of the Könisgberg (ii) and prewar Magdeburg. They formed the basis of the KMS Emden (iii) built in the 1920s for the Reischmarine.

Development of the new Könisberg class

The design was an incremental improvement over the previous Wiesbaden class, itself derived from the previous Graudenz which innovated with 15 cm main guns. Logically the hull was lenghtened as displacement, but with the same armament, speed, and armor protection overall. This enabled to improved a bit ASW protection and make the ship roomier in general. But other than that it was pretty much a repeat of the previous design.

Construction

Königsberg (ii) was ordered as “Ersatz Gazelle”, supposed to replace the old 1900 cruiser. She was laid down at AG Weser shipyard, Bremen in 1914, launched on 18 December 1915, commissioned on 12 August 1916. Emden (ii) was originally ordered as “Ersatz Nymphe” at AG Weser in 1914, launched later on 1 February 1916, commissioned on 16 December 1916. SMS Karlsruhe (ii) was ordered as Ersatz Niobe, laid down in 1915 at Kaiserliches Werft in Kiel, launched on 31 January 1916 fitting-out and commissioned on 15 November 1916. SMS Nürnberg(ii) was laid down as Ersatz Thetis at Howaldtswerke Werft, also in in Kiel, in 1915. She was launched on 14 April 1916, commissioned on 15 February 1917. Therefore, their service life was short compared to previous cruisers of the German Imperial Navy.

The design made the basis, natuarlly, for the next Cöln-class cruisers, which were few to see service before the end of the war. In turn, the latter were the starting point for designers making the sold cruiser authorized for the Reichsmarine under the Versailles treaty in the 1920s and declared as a school cruiser, SMS Emden (third of the name in a decade), but they started on the blueprints for Karlsruhe not the Cöln, which disappeared. The design was simply strecthed out and improved. Personnel shortages in the design staff, closure of the Navy’s Ship Testing Institute meant no new revolutionary design could be made in time. This changed in 1926.

Design of the Könisberg class


Karsruhe Scapa Flow 1919

Hull and general design

With 145.80 meters (478 ft 4 in) long at the waterline, up to 151.40 m (496 ft 9 in) long overall, they were the longest cruisers of the Kaiserliches Marine since the Scharnhorst class armored cruisers (144 m). The beam was larger than the previous class at 14.20 m (46 ft 7 in) versus 13.90 m (45 ft 6in) and a draft of 5.96 m (19 ft 7 in) also more pronounced forward and up to 6.32 m (20 ft 9 in) aft (versus 5.76m for the Wiesbaden). Designed displacement was 5,440 metric tons (5,350 long tons), and fully loaded, battle ready, 7,125 t (7,012 long tons). It was almost 1,000 tonnes heavier than the Wiesbaden.

Their hulls used the same techniques as before, with longitudinal steel frames, divided into eighteen watertight compartments, one more than on the Wiesbaden, plus the now usual double bottom extending for 49% (versus 47%) of the keel. Complement remained the same, 17 officers and 458 enlisted men. Their onboard service boats fleet was located on davits alongside the funnels, amidships. It included a picket boat, a supply barge, a cutter, two yawls, and two dinghies.

Powerplant

The propulsion systems comprised two steam turbines driving two three-bladed screws 3.50 m (11 ft 6 in) in diameter. SMS Karlsruhe was the only one outfitted with two sets of high-pressure geared turbines. These steam turbines were fed by ten coal-fired boilers, plus two oil-fired double-ended boilers. In total, the output was 31,000 shaft horsepower (23,000 kW) for 27.5 knots (50.9 km/h; 31.6 mph) and on trials, the lead ship, SMS Königsberg managed to make 45,900 shp (34,200 kW) for 27.8 knots (51.5 km/h; 32.0 mph), Karlsruhe 55,700 shp/27.7 knots, Emden 50,216 shp/27.7 kn, while Nürnberg skipped this part. Trials were conducted in shallow water but in deep water they were supposed to reach 29 knots (54 km/h; 33 mph). This was about the same as the previous Wiesbaden.

Autonomy was 4,850 nautical miles (8,980 km; 5,580 mi) at 12 knots (22 km/h; 14 mph) cruising speed, down to 1,200 nmi (2,200 km; 1,400 mi) at top speed (27 kts). They carried 350 t of coal as designed, but in wartime or in practive when all voids were filled, up to 1,340 t. Fuel oil carried only initially was 150 t but again, by filling voids, up to 500 t in operations. Electrical power came from two turbo generators, one diesel generator, and a total of 300 kilowatts/220 volts.

They were generally regarded as good sea boats with gentle motion, and thanks to their slighty improved rudder and reworked stern, were highly maneuverable, with tight turning radius, but bleeding speed going in hard turns, due to their lenght ratio, ideal to ride waves in the north sea. Hard rudder, they lost 60% speed and were generally stern-heavy.

Armament


Profiles on Kombrig

Main: 8x 15 cm (5.9 in) SK L/45 guns

All were mounted on single pedestal mounts, two in tandem forward (forecastle), four on the sides amidships, two in superfiring pair aft. Same as for previous carriers, they were able to engage targets at 17,600 m (19,200 yd). 1,040 rounds were carried total (130 per gun). They fired 45.3-kilogram (100 lb) HE shells at 840 meters per second (2,800 ft/s), with max elevation 30°.

Secondary: 2x 8.8 cm (3.5 in) SK L/45

The ships’ light battery was mostly for antiaircraft pusposes. Unlike the Wiesbadens, they were not planned with four 5.2 cm (2 in) L/55 guns but were fitted insted with two of the excellent 8.8 cm (3.5 in) SK L/45 models. They were placed on the centerline astern of the funnels, and fired a 10 kg (22 lb) shell at 750-770 m/s (2,500 to 2,500 ft/s).

Torpedo Tubes & Mines

They also carried four 50 cm (19.7 in) torpedo tubes, with one torpedo reload for each, two were submerged, broadside, two were on the upper deck amidships on swivel mounts for traverse. Like previous cruisers they could be equipped with rails to carry 200 mines, instead of the 120 of the Wiesbadens, thanks to their greater lenght.

Protection

These vessels were understandably lightly protected, as previous cruisers. But still, for the Wiesbaden and Frankfurt their waterline armored belt was 60 mm (2.4 in) thick amidships, tapereed down to 18 mm (0.71 in) forward. The stern was unarmored. The conning tower was the strongest part of the ship with walls 100 mm (3.9 in) thick, topped by a 20 mm (0.79 in) roof. The rangefinder atop was protected by 30 mm (1.2 in) plating. The deck had 6 cm (2.4) plating forward, tapered down to 40 mm (1.6 in) amidships, 20 mm (1.1 in) aft with sloped armor 40 mm thick, which connected the deck and belt armor. Gun shields for the 15cm guns were 50 mm (2 in) thick. In contrast, the Königsbergs had the following, with a belt and deck made of Krupp cemented steel:

  • Main Belt 60 mm (2.4 in) amidships, 18 mm (0.71 in) fwd
  • Armored deck 40 mm (1.6 in) amidships, 20 mm (0.79 in) stern, 60 mm forward
  • Connecting sloped armor 40 mm thick
  • Conning tower 100 mm (3.9 in) sides, 20 mm roof
  • Main battery gun shields 50 mm (2 in)
  • Mine Hold 20 mm thick deck, 30 mm side armor

General assessment

Metz in French service
Metz in French service, ex-Koenigsberg

Not amazing compared to previous vessels and arriving too late in service, Königsberg and Nürnberg saw action still at the Second Battle of Heligoland Bight. They escorted minesweepers clearing paths in British minefields, which saw HMS Repulse engaging Königsberg (hit, minimal damage, fire mastered). All four sister ships also participated in Operation Albion in the Gulf of Riga. Emden proved she could be used as Torpedoboats flagship and leader, with success.

By late (October) 1918 they were all four mobilized for a final grand attack, with very agressive objectives: Königsberg, with Cöln, Dresden, and Pillau were to enter the Thames estuary. Karlsruhe, Nürnberg, Graudenz shell the Flanders to draw out the British Grand Fleet. Reinhard Scheer’s plans were marred by mutinies and the operation cancelled. In the end, after a period of inactivity they were partly conducted to Scapa Flow, but two ended was war reparation cruisers, to France. They were appreciated as the scout cruisers France planned in 1912 but never built.


KMS Emden(iii) off China, 1931

So design wise, they were as good as their predecessors and on part with British designs of the time, notably the “Town” and C class cruisers, all armed with 6-in guns, but they had more. Typically a C-class of 1916 was smaller and had five main guns, 4,000 tonnes, 29 knots and less torpedoes. None of them encountered the Königsberg(ii) class cruisers in actions, which were rare. It seems the French were quite happy with their design, maintained all the way through the end of the interwar without much modifications.

Kaiserliches Marine

Kaiserliche Marine SMS Königsberg


SMS Königsberg was launched on 18 December 1915 without fanfare, followed by a quick fitting-out work, and commissioned after sea trials and fixes on 12 August 1916. From the 29th, she was reassigned to the II Scouting Group as flagship. Kapitän zur See Ludwig von Reuter took command, hoisting his flag aboard and she spent her early time in coastal defense patrols in the German Bight, Pillau, Frankfurt, Graudenz, and Regensburg, for the German North Sea coast defence agains any RN intrusion, notably minelayers. Vizeadmiral Reinhard Scheer at the time was rather in favor of the U-boat campaign and often uneventful patrol duties alternated with a Baltic Sea training exercize from 22 February to 4 March, 20 May to 2 June. She was in dydock for maintenance from 16 August to 9 September.

Her first serious combat mission was Operation Albion: She was tasked to support amphibious assault on in the Gulf of Riga, to allow the German Army to advance further. One of the objectives was to eliminated the Russian naval forces present, and the combined fleet planned to take Ösel Island and the Sworbe Peninsula gun batteries, implying a landing. Königsberg was in Kiel on 23 September to prepare, the rest of II Scouting Group escorting the troop transports while she became flagship of IV Transport Group, visited and briefed by Ludwig von Estorff, commander of the 42nd Division which was escorted. The fleet stopped in Libau on 25 September for final preparations and departed on 11 October, starting the following day by SMS Moltke (III Squadron) shelled Tagga Bay and the IV Squadron the Sworbe Peninsula, Saaremaa.

SMS Königsberg was in Tagga Bay for the coordination of the infantry landings, and Russian opposition failed; On 18–19 October, she was to cover minesweepers operating off Dagö, marred by bad weather. On the 19th with SMS Nürnberg and Danzig she was sent to intercept two Russian torpedo boats, but they could not be found. The following day, the operation was a success, and the Admiralstab ordered the fleet back in the North Sea. On 28 October, SMS Königsberg stopped in Libau on her way and returned to patrols with the II Scouting Group.

Next, she took part in the Second Battle of Helgoland Bight, still with II Scouting Group and torpedo boats, escorting minesweepers of the II Minensuchflotille in Horns Rev, SMS Kaiser and Kaiserin in distant support. Reuter sent Nürnberg forward in reconnaissance, and she soon spotted the incoming British 1st Cruiser and 6th Light Cruisers Squadrons, supported by the 1st Battlecruiser Squadron. Reuter orders his remaining cruisers forward too to distract the British while the minesweepers withdrew under smoke screen; Next the cruiser’s orders were to draw the squadrons towards the German battleships.

Eventually HMS Courageous, Glorious, and Repulse arrived in turn, engagede Kaiserin and Kaiser while Reuter attacked with the cruisers, Repulse hitting Königsberg with with a main shell at 10:58. All three funnels were razed and fire raged. She fell to 17 kn while Reuter transferred his flag to Pillau. She eventually withdrew and the fire was suppressed, and she came back, buy the British broke off their attack and more German reinforcements were signalled. Next, she covered the IV Battle Squadron (Flagship Friedrich der Grosse, VAdm Wilhelm Souchon) during a sweep for any remaining British vessels, for nothing, retreateing at 15:00

Königsberg was back in the Schillig roadstead at 19:05 and listed twenty-three casualties, with eight deads. The general staff criticized Kurt Graßhoff leading the battleships not to have been closer. This became a new guideline to protect minesweeper groups. Meanwhile, Königsberg was in repairs at Wilhelmshaven until 15 Decmber.

Königsberg was flagship again of her unit, proceeding to more patrol duties in the German Bight, until 20 January 1918, when Reuter was replaced by KzS Magnus von Levetzow. The II Scouting Group made Baltic exercizes (21 January to 7 February) and in all afterwards, took part in five fleet sweeps, incuding the 23–24 April raids against convoys to Norway. Moltke having a serious accident led Scheer to break off prematurely. Anothe sweep took place on 10-13 May, escorting the minelayer Senta laying an ASW defensive minefield in the Bight. After another training session in the Baltic on 11-12 July. Levetzow joined the Seekriegsleitung or Maritime Warfare Command, replaced by KzS Victor Harder, still making Königsberg his flagship.

In October 1918, Königsberg with Cöln, Dresden, and Pillau (II group) were prepared for a final raid on British waters, her role being to attack merchant shipping in the Thames estuary. But on 29 October, widespread mutiny had the operation cancelled. Nevertheless, Kommodore Andreas Michelsen organized an attack group with sixty ships including Königsberg as reports came on 9 November reports of British activity but the reports proved false. Following the abdication, ceasefire and peace talks, it’s KMS Königsberg that carried RADM Hugo Meurer to Scapa Flow to negotiate the german fleet fate with Admiral David Beatty, notably the place of internment. She was in Scapa on 15 November with a white flag. Later the High Sea Fleets met a combined allied fleet as prearranged and was conducted to Scapa, but Königsberg remained in Germany, coming back with Meurer.

Stricken on 31 May 1920 after prolongated inactivity, she was eventually ceded to France as war reparation under the name “A”. She sailed in Cherbourg on 20 July, renamed “Metz” on 6 October and re-entered service with the French fleet (see WW2 French Cruisers for more).

Kaiserliche Marine SMS Karlsruhe

SMS Karlsruhe

SMS Karlsruhe was commissioned on 15 November 1916 but trained without assignment until 22 February 1917, before joining II Scouting Group. She multiplied patrols in the German Bight and supported minelaying/minesweeping operations, starting on 5 March; followed by another on 6 April. There, she led the 2nd Torpedoboat Half-Flotilla to the Amrun Bank to U-22, damaged, which needed help. On 16 August she took part in a minesweeping operation in the North Sea, Route Yellow used by U-boats. She sailed with SMS Frankfurt and three torpedo boats and at some point lookouts spotted a British squadron of three light cruisers, sixteen destroyers and the minesweepers withdrew but when Karlsruhe and escort failed were too far way to help them.

Karlsruhe also took part in Operation Albion: By early September 1917 she took part in the invasion of the Gulf of Riga. On 18 September she was prepared for the operation as part of the II Scouting Group she was the cruiser screen for the task force, departing on 24 September from Kiel via Libau and carrying infantry on 26 September to Putziger Wiek to be reloaded on capital ships, before turning back to Libau on 2 October, embarking the Saxon Radfahr-Bataillonen and departing on 11 October, leading the 2nd Transport Group.
The operation went on by 12 October and Karlsruhe landed her infantry ashore in Tagga Bay, covering also ten transport ships on 17 October, escorted back to Libau. She also was to cover minesweepers off Dagö and was back to the North Sea via Kiel on 27 October, followed by a drydock maintenance on 16 November-6 December.

By early April 1918 she assisted the laying of a defensive minefield in the North Sea for a next month major fleet operation, abortive (23–24 April) to attack British convoys to Norway. Moltke indeed had a serious machinery issue and Scheer cancelled it. On 10 to 13 May she escorted the minelayer Senta for another defensive minefield inthe way of the usual route of British submarines to the German Bight. She also escorted SMS Baden and trained in the Baltic 11-12 July, still under Kapitän zur See Magnus von Levetzow, followed by a maintenance from 1 August.

She took part in the evacuation on the coast of Flanders on 14 August after the Battle of Amiens, loaded 70 mines to participate in a later cancelled operation with Brummer and Nürnberg, the latter being drydocked for repairs. After training in the Baltic on 16-23 October, and patrolling the German Bight she was prepared for the final attack in November, cancelled due to mutinies. After the capitulation she sailed under Rear Admiral Ludwig von Reuter to Scapa Flow, hosting the II Scouting Group commander, KzS Victor Harder. On the morning of 21 June at 11:20 she received the order to scuttle, and sank at 15:50, one of the last ships to do so, latter never raised for scrapping as she was in a greater depth, but part of her wreck was extracted as she was sold in 1962. The wreck was surveyed in 2017 by marine archaeologists from the Orkney Research Center for Archaeology, under 25 m (82 ft), a popular diver’s attraction.

Kaiserliche Marine SMS Emden


SMS Emden (ii) was commissioned on 16 December 1916 and became in October 1917 flagship for Commodore Paul Heinrich torpedo-boats Cdr, assigned for Operation Albion. On 12 October, she shelled a Russian battery at Pamerort and covered the landings afterwards. She latter spotted two Russian destroyers but they were shelled and chased off. On the 13th, an attack by eight Russian destroyers was met by Emden which moved forward at 07:45 in the German screen, opening fire on the three leading ones from 13,800 meters (45,300 ft), straddling them and destroying the wireless equipment of Grom. She shelled on two others at 09:30 but weather deteriorated. Still the signal station at Pamerort assisted Emden to dive them off. At 12:20, the Russian gunboat Chivinetz brought her heavy guns to deal with the cruiser, with two destroyers, briefly engaging Emden, which straddled her until she retreated.

On the 14th, covered the mine-clearing of Kassar Wiek between Dagö and Ösel with the battleship Kaiser, entering the Soelo Sound to support torpedo-boats sweeping the area. Emden spotted and fired on four Russian destroyers, which retreated. Kaiser scored a hit on Grom, which took a list. The others were driven off. She latter shelled Dagö at 15:00. On the 18th, she started again, firing 170 shells until the Russians retreated and on the 20th, the island was under German control.

On 11 December 1917, she led a raid on British shipping in the North Sea with the II TB Flotilla, split in half off the Dogger Bank, some spotting and sinking four of six steamers located. After the Armistice, she departed under RADM Ludwig von Reuter to Scapa Flow. But as he was harrassed by disgruntled sailors on the battleship Friedrich der Grosse he transferred flag on Emden, which was cuttled on 21 June at 11:20 but did not sink. The British managed to tow her close to shore, beached and re-floated, then assigned to the French Navy on 11 March 1920, used as a target, finished off with explosives and BU in Caen in 1926.

Kaiserliche Marine SMS Nürnberg


SMS Nürnberg was commissioned on 15 February 1917, under Fregattenkapitän Walter Hildebrand. After sea trials lasting until 1st May, she joined the II Scouting Group patrols in the summer, before being mobilized for Operation Albion in September 1917, where Nürnberg and the II Scouting Group under RADM Ludwig von Reuter was in the cover screen, from 11 October, with a contingent of soldiers aboard while escorting several transport ships with the landing force, collier and tugboats, arriving in Tagga Bay

Nürnberg started landing troops, covered by Königsberg. The operation was over on 20 October, and she was back in the North Sea, but not before she departed on 24 October via Libau and Kiel. However she took part in the second Battle of Helgoland Bight : On 17 November with Königsberg, Frankfurt, and Pillau she covered a minesweeping operation in the Helgoland Bight, supported at a distance by Kaiser and Kaiserin, when the minesweepers were attacked by a force of cruisers, with Six British battlecruisers in support. The minesweepers retreated under a smoke screen and Nürnberg opened fire on the British cruisers at 08:55 from 11 km (6.8 mi) before being straddled in turn by the British cruisers and the HMS Courageous and Glorious.

Due to the poor weather she was not hit directly, but showered with shell splinters, having light casualties although this is disputed. She returned fire and was “saved” at last by the arriving Kaiser and Kaiserin while Hindenburg arrived in reinforcement and both sides folded back.
Under her new commander Hans Quaet-Faslem by January 1918, she had a peacful late career, under overhaul in March-May, covered a minelaying operation on 10-13 May and sortied to catch the British aircraft carrier HMS Furious after the Tondern raid in July. She changed captain again for Wolfgang Wegener.

In October 1918 she was to take part in the next month climactic attack mobilizing the whole Hochseeflotte, Nürnberg, Karlsruhe and Graudenz were assigned to the Flanders attack. On 29 October order was given to regroup in Wilhelmshaven but the following night, desertions and massive mutinies led to the cancellation. Nürnberg was to sail to Scapa flow for internemt latern departing on 19 November, arriving on the 27th. Captain Wegener went back to Germany, leaving Kapitänleutnant Günther Georgii and a skeleton crew in charge. They scuttled the ship on 21 June, but British sailors approached and used explosive charges to blast her anchor chains so that she could be dragged aground before sinking slowly.

She was refloated in July, towed to Portsmouth, and converted into a target ship, at first fired at by HMS Terror on 5 November 1920 from 370 m (400 yd) and she listed 10° to simulate long range angle. Terror tested a 7.5 in and a 6 in gun and different shell types. This went on also on 8 November. On 7 July 1922, she was eventualy properly sank by HMS Repulse off the Isle of Wight.

Wiesbaden class cruisers (1915)

Wiesbaden class cruisers (1915)

Germany – SMS Wiesbaden, SMS Frankfurt (1914-1919)

Hipper’s Cavalry

Among the light cruisers screening for the Kaiserliches Marine, were the modern and active SMS Wiesbaden and Frankfurt: They were screening Admiral Franz Hipper’s battlecruisers (1st scouting group) in early sorties and fought notably at Jutland. Very similar to the previous Graudenz class, but up-armed with 15 cm SK L/45 guns and capable of 27.5 knots. Wiesbaden’s career ended at Jutland, badly damaged and eventually sank in the early morning hours while Frankfurt was only lightly damaged and went on with the II Scouting Group in Operation Albion and Second Battle of Heligoland Bight in 1917.

Development of the Wiesbaden class


SMS Frankfurt in Scapa Flow, 1919

Technically these cruisers were just an incremental step in light cruiser design. Planned in 1912 as part of the naval program, as improved Graudenz class, only two were built, laid down in 1913. They were very similar but armed with eight 15 cm SK L/45 guns instead of the twelve 10.5 cm SK L/45 guns on the earlier cruisers, a radical firepower upgrade that was a result of recent evaluation and tactical use as screening vessels. It went from “destroyer killers” to “cruisers killers”. Ie. their role went to chasing out enemy’s own flotillas, generally led by light cruisers, to combat their opposite screening forces, which cruisers the time were all armed with 6-in guns, like the prolific “Town” class.

And apart a reviewed protection for better standing 6-in shells damage (they could not be stopped anyway), it was joined with a better speed of 27.5 knots (50.9 km/h; 31.6 mph) to also give them a fair advantage and the ability to out-run their enemy and choose their distance of engagement. This was especially true for the Hochseeflotte which planned them to serve on the north sea, which vibility was poor most of the time, between bad weather and fog. The Royal Navy when designing their cruisers were less specific about the theater of operation due to the needs of their large empire and numerous trade routes.

SMS Wiesbaden was ordered under the contract name “Ersatz Gefion”. She was laid down at AG Vulcan shipyard, Stettin, in 1913. She was launched on 20 January 1915 and fitting-out work started. Her sister Frankfurt was ordered under “Ersatz Hela”, laid down at the Kaiserliche Werft, Kiel, also in 1913, launched later on 20 March 1915 but fitting-out work proved faster and she was completed earlier.

Construction was relatively long, delayed due to other more priority works after the war broke out. But they were eventually launched on January and March 1915, and completed in August 1915, Frankfurt ten days before her sister ship. The class is still named in most publications after the led ship launched. Completion and fitting out work was very short in order to have both pressed into service as soon as possible. In between the Graudenz and Wiesbaden built at Vulkan and Kiel, little experience could be integrated from cruisers classes built in between: The Pillau were Russian designed ships, requisitioned and modified, and the Brummer were minelayers.

Design of the Wiesbaden class


SMS Frankfurt seen from profile

If taking of the previous Graudenz class as reference (both were launched in 1913 and 1914); the new Wiesbaden were a bit larger, perhaps 300 tonnes more in displacement fully loaded, a few meters longer (145.3m/476 ft versus 142.7m/468 ft overall), just 10 cm (4 in) wider, but they generally shared a similar design and outlook, with two equal masts fore and aft, three raked funnels of equal size and span, a forecastle, a bulwark covered amidship section and a lower aft deck, clipper bow and round stern.

In many way they confirmed the design standard repeated for the next wartime Königsberg (ii) -four ships- and the final Cöln class flirting with 7,500 tonnes (11 ships planned, two completed too late to see action). They could be seen as well as the forebears of the interwar KMS Emden, first “modern” german cruiser.

Hull and general design

The hull followed the usual scheme of longitudinal steel frames. Their crew comprised 17 officers and 457 enlisted men, a bit less than the previous Graudenz which had more guns (albeit of a smaller caliber), so they felt roomy. They carried for service boats a single steam picket boat, a supply barge, a cutter, two yawls and two dinghies, man-rowed but with optional sail.

Apart changes in armament, the new cruisers had a bit more power, but their simhouette remained the same. The bridge was separated entirely from the forward conning tower, on which was installed the main telemeter. The enclosedd winter deck with wings was topped by the open battle deck with lookouts and signals post. The two equal masts were composed of two parts, the lower being thicker and supporting a lightly armored observation post. Contrary to the Graudenz, there were equal fore and aft, covering the observer from the elements and from shrapnels.

The central section, about 1/3 lenght was dotted by the three funnels, truncated from all the pipes, with ventilation louvres on uptakes fore and aft of these. Two flak guns (8.8 cm) were installed either side of the middle funnel. Six service boats were fitted under davits on the sides and extra space was allocated aft of the third funnel, at the foot of the aft mast. The latter also supported a watch platform, a small radio room, and aft main telemeter for the two superfiring guns. Four night projectors were located on invidual platforms on each mast, one over the other, covering the front and back.

The Wiesbaden class propulsion systems consisted of two sets of Marine steam turbines. Each drove a single three-bladed 3.5-meter (11 ft) screw propeller. In total, ten coal-fired Marine-type water-tube boilers and two oil-fired double-ended boilers provided an output of 31,000 shaft horsepower (23,000 kW). Top speed as designed was 27.5 knots (50.9 km/h; 31.6 mph). Sea trials speeds are not known, but generally superior to those planned on German cruisers.

For range, they carried 1,280 metric tons of coal plus an additional 470 metric tons of oil making for a total of 4,800 nautical miles (8,900 km; 5,500 mi) at 12 knots cruise speed. At 25 knots as tested (46 km/h; 29 mph) it was down to to 1,200 nmi (2,200 km; 1,400 mi). Wiesbaden and Frankfurt each had a pair of turbo generators, but only the first had an extra diesel generator, rated for 300 kilowatts (400 hp) at 220 Volts. SMS Frankfurt reached only 240 kW (320 hp) however she also differed by having a hydraulic drive on one shaft, and geared cruising turbine on the other as an experiment. Steering on both vessels was controlled by a single rudder and they were considered good steamers and responsive at the helm, good weapons platform with a moderately slow and predictable roll.

Armament

Main Guns: 8x 15cm SKL/45

The Wiesbaden class made their greatest changed compared to all previous cruisers (and it was time!) by replacing the usual 10.5 cm (4 in) battery by a far more potent main battery of eight 15 cm (5.9 in) SK L/45 guns, all also in single pedestal mounts with different locations:

-Two were placed side by side (tandem) forward on the forecastle
-Four located amidships, two per side
-Two were placed in a superfiring pair aft.

The SK L/45 became the mainstay of secondary armament on battleships and cruisers in the German Navy. It was studied from 1906, introduced first in capital ships like the Kaiser and König class, but the Wiesbaden were the first to introduce these. They were also used by subsequent vessels of the Pillau, Brummer, Königsberg (II), Dresden (II) classes, and KMS Emden in the 1920s, spared later being used on the many auxiliary cruisers seeing action in WW2, notably KMS Atlantis against Sydney. Many cruisers were also rearmed in 1915-16 with these guns.

These guns fire an HE or AP shell both 99.8 lbs. (45.3 kg), with a rate of fire of about 5-7 rounds per minute, and range of 17,600 m (19,200 yd). In total 1,024 rounds of ammunition was aboard, so for 128 shells per gun. More on navweaps

Main Guns: 4x 5.2cm SKL/55

Since the design was studied in 1913, antiaircraft armament was planned from the start, and comprised four 5.2 cm (2 in) L/55 guns. They were located amidship, abaft the third funnel, but later replaced with just two 8.8 cm (3.5 in) SK L/45 anti-aircraft guns with high-angle mountings.

Torpedo Tubes: 4x 50cm Torpedoes

As previous cruisers, the new cruisers carried torpedo tubes, four 50 cm (19.7 in) two submerged braodside, two on the upper deck, with eight torpedoes in store. The Wiesbaden class was also design to be able to carry mines, 120 of them stored on the deck rails running aft.

Protection

SMS Wiesbaden and Frankfurt had the following:
-Waterline armored belt 60 mm (2.4 in) thick amidships.

-Forward belt tapeered down to 18 mm (0.71 in).
-No stern belt.
-Forward Conning tower 100 mm (3.9 in) walls, 20 mm (0.79 in) thick roof.
-Rangefinder atop 30 mm (1.2 in) armor protection.
-Main armored deck 60 mm thick armor plate forward, 40 mm (1.6 in) amidships, 20 mm aft.
-Sloped armor 40 mm thick, connecting deck to belt armor.
-Main battery gun shields 50 mm (2 in) thick.
-Seventeen watertight compartments
-Double bottom 47% keel lenght.

Kaiserliche Marine SMS Wiesbaden


SMS Wiesbaden 31 May 1916, Gettyimages

SMS Wiesbaden was commissioned into the High Seas Fleet, on 23 August 1915, while her sea trials were rushed out (perhaps why nio data is available for test speeds). Her career in the winter was spent with uneventful patrols and training sorties as part of the II Scouting Group (also Lebing, Königsberg and her sister ship). The latter on 24 April 1916 had her taking part in Raid of Lowestoft at last. But only her sister saw some action, not her. As part of the screened force she did not have the occasion to fire one shot apart on Yarmouth and Lowestoft, but damage was light; The operation had been almost a complete failure as just two patrol craft were sunk, in exchange of a badly damaged battlecruiser. But her real test came with the spring of 1916.

Under Command of Kapitan zür zee Fritz Reiss, SMS Wiesbaden was still assigned to II Scouting Group, headed by Konteradmiral Friedrich Boedicker and operating alongside the I scouting group as the forward screening force, departing on 30 May with Hipper’s battlecruisers. Wiesbaden and Frankfurt served teamed together, her sister as Boedicker’s flagship. She was cruising to starboard on the formation, on the disengaged side when Elbing, Pillau, and Frankfurt engaged the British screen.

Circa 18:30, SMS Wiesbaden spotted and fired on the cruiser HMS Chester, scoring several hits, but both sides disengaged, spotting Rear Admiral Horace Hood’s battlecruisers. HMS Invincible fired on Wiesbaden and managed to land a lucky hit, penetrating the unprotected aft deck and exploding in her engine room. The damage was so extensive the cruiser bled speed to a crewl, while Konteradmiral Paul Behncke ordered his dreadnoughts Wiesbaden, in a vain hope the crew could repair the damage.

But at the same time, the British 3rd and 4th Light Cruiser Squadrons closed earlier to make a massive torpedo attack on the German line, while shelling Wiesbaden with their main guns at the same time. Then, the destroyer HMS Onslow closed within 2,000 yards (1,800 m), firing a single torpedo with sure results on a siotting duck. Hit below the conning tower forward, the hull shook violently, but thanks in part due to the compartimentation, she still remained afloat. The melee which followed was absolutely chaotic and fierce, with the crew of Wiesbaden right in the middle of the storm, witnessing fire from all sides. They saw the armored cruiser HMS Defence blew up, HMS Warrior fatally damaged. The German cruiser’s captain decided to launch her torpedoes in this, and managed to score against the battleship HMS Marlborough.

Shortly after 20:00, the German III Flotilla of torpedo boats attempted, not to defend, but just to evacuate her crew. They were pushed back by a dense fire from the British battle line. Another attempt was made but in the darknes they could not spot the stranded cruiser. Eventually she was left to her fate. Wiesbaden sank without witness at circa 01:45 up to 02:45. One crew member survived though, picked up by a Norwegian steamer on 1st June. The whple crew of 589 disapperaed behind the waves, probably surviving for some time swimming for some, but never found. Among these was the well-known poet and essayist Johann Kinau, aka “Gorch Fock”. Her wreck was found in 1983 by divers of the German Navy. The screws were salvaged and she was classed as a war grave, found lying upside down, the last vessel of the battle to be discovered.

Kaiserliche Marine SMS Frankfurt

SMS Frankfurt was commissioned on 20 August 1915 and like her sister ship due to the war, she rushed out her sea trials, being assigned to the II. scouting group.

Raid on Lowestoft

After months of training she took part at last in her first operation, the Bombardment of Yarmouth and Lowestoft, on 24 April 1916. As part of the screen of the I Scouting Group (Franz Von Hipper’s battlecruisers) and under command of Konteradmiral Friedrich Boedicker she spotted, attacked and sank a British armed patrol boat off the coast during the bombardment. Reports of submarines and torpedo attacks had Boedicker breaking off and ordered to sail full speed back east, towards the High Seas Fleet awaiting further away to destroy any chasing British force. Vice Admiral Reinhard Scheer, C-in-C, was warned of the Grand Fleet rushing out of Scapa Flow in hot pursuit and ordered a general withdrawal.

Jutland

Next action was not long to follow, still in the same unit with her sister she sailed on 31 May, as Boedicker’s flagship, II Scouting Group commander, screening for Hipper’s I Scouting Group. Frankfurt spotted their British’s screening counterpart and opened fire, with the battlecruiser squadrons closing fast behind. Frankfurt, Pillau, and Elbing were on the right side of the engagement and duelled with British light cruisers at 16:17, until the British, having many hits, folded away. But 30 min. later the 5th Battle Squadron’s fast battleships arrived and started to fire at SMS Frankfurt, which fled under a smokescreen, unscaved.

At around 18:00, the destroyers HMS Onslow and Moresby found and attacked the German battlecruisers, but were repelled by Frankfurt and Pillau. 30 min. later, Frankfurt spotted and engaged the cruiser HMS Chester, scoring several hits. Rear Admiral Horace Hood battlecruisers in turn arrived on the scene, opened fore and hit her sister Wiesbaden, disabled and later left behind. About 19:30 as darkness fell, HMS Canterbury scored four hits on Frankfurt, two 6-in around her mainmast and two 4-in forward above the waterline, and near the stern, damaging both screws.

Frankfurt and Pillau spotted HMS Castor and several destroyers at about 23:00 and fired each a torpedo at the cruiser before folding on the German line, searchlights shut not to be spotted. It was past well past midnight when Frankfurt met two British destroyers at close range, firing on them briefly and retreated; At around 04:00, 1 June, the entire fleet had managed to reach Horns Reef and Frankfurt had “only” three men killed and eighteen wounded, having fired 379 rounds or her main guns, some of her 8.8 cm guns and a single torpedo. Her captain found himself lucky to have escaped the fate of her sister ship.

Operation Albion and Heligoland

Next was Operation Albion, in October 1917. The goal was to drive off the Russian naval forces of the Gulf of Riga. Still in the II Scouting Group under command of RADM Ludwig von Reuter, she did her share of the action but did not fired a shot. In November, SMS Frankfurt and the II Scouting Group took part in the Second Battle of Heligoland Bight. With the three other cruisers of her unit she escorted the minesweepers clearing paths in British minefields around the contested island.

SMS Kaiser and Kaiserin were in distant support in case of need, and during the British attack, Frankfurt fired torpedoes at incoming British cruisers, but missed. The British eventually broke off as German battleships came to the rescue. All withdrew soon after.

On 21 October 1918 in the evening, SMS Frankfurt accidentally rammed UB-89 in Kiel-Holtenau. The schock not only sunk the submarine, it also killing seven of her crew but 27 survivors were still pulled from the water. UB-89 was would be later raised by the salvage vessel Cyclop on 30 October but never repaired.

Later career and end as a target ship


18 July 1921 US coast air attack test: Frankfurt is bombed.


Frabkfurth is burning


Sinking.

Scheer and Hipper had the project of a last massive sortie with the while fleet “for honor” after months of inaction, and trying to gain a better bargaining position for Germany in the peace treaty. On 29 October 1918, Frankfurt’s captain was ordered to sail to Wilhelmshaven but miutinies during the night of the 29-30 and further unrest during teh day forced Hipper to cancel the operation. Frankfurt was later summoned by the treaty’s condition to be interned in in Scapa Flow under overall command of Admiral Reuter.

While negotiations went on, she as prepared for scuttling and on 21 June 1919, as Reuter believed the deadline was about to end for the allied seizure of the fleet, he waited for an opportunity, which presented itself on 21 June when the Grand fleet left Scapa Flow for maneuvers. Ar 11:20 order to scuttle the ships was given. However Frankfurt was close to the coast and was swiflty boarded by British sailors when what happened was now obvious, and under gunpoint, even after the cocks were opened, they managed to have the ship beached before sinking. Raised in July, she was transferred to the USN as war prize.

From 11 March 1920 she was taken over, and then recommissioned on 4 June 1920, still in Britain. Instead of repairing her damage for subsequent service it was decided to have her “spent” as a target for experiments. She was taken in tow by the minesweepers USS Redwing, Rail, and Falcon to Brest, France, together with the battleship SMS Ostfriesland also a war prize. The three minesweepers towed three ex-German torpedo boats for good measure, creating a nice “target flotilla” which was not dealt on situ but rather escorted in convoy across the Atlantic to NYC Navy Yard. Inspection by naval engineers was long and exhaustive in order to gain lessons to apply to US ship design.

Her watertight compartments were completely sealed in order to have her survive extensive damage and on July 1921, the US Army Air Service and US Navy conducted bombing tests off Cape Henry in Virginia. They were at the initiative of WW1 ace and war hero, now General Billy Mitchell, to convince the Navy of the potenty of naval aviation and the threat it posed to traditional fleets. The “target fleet” was buffed up further by the adition of the old, stricken 1890s battleship USS Iowa. Tests started on 18 July with air attacks performed at first with small 250-pound (110 kg) and 300 lb (140 kg) bombs. Damage was minimal, then tests started with 550 lb (250 kg) and then 600 lb (270 kg) bombs using Martin MB-2 bombers. Frankfurt took several 600 lb bombs and sank that day at 18:25.

Brummer class cruisers (1915)

Brummer class (1915)

Germany (1913-1919) – SMS Brummer, Bremse

In 1915, the Admiralty decided to start construction in Vulcan, Stettin, of two large turbine-powered minelayer vessels. Launched in December 1915, March 1916, commissioned in April and July 1916. These were very active and successful ships until the end of WWI.

Design development

Brummer_1915bp In order to strengthen or replace Albatross and the Nautilus, the only mine-laying cruisers in the German fleet, the Admiralty decided to start construction in 1915 at Vulcan, Stettin, of two large vessels dedicated to this task, better armed than the frail light cruisers of 1906. The Brummer and the Bremse were launched in December 1915 and March 1916 and accepted in April and July 1916. Decision to build them was also facilitated by the presence of turbines built to propel the Russian battle cruiser Navarin, whose construction was canceled due to the war. So they were quite powerful as a result.

In the end, these mixed ships, running on coal and fuel oil, were able of way than 28 knots (29.5 on trials), and developed more than 42,000 hp (Brummer) and 47,000 (Bremse) during the same trials. Their career was quite intense: SMS Brummer was part of the 2nd and then the 4th fleet. In January 1917 she participated with Bremse in the great minefield laid between Norderney and Helgoland. In October, she was detached with her sister-ship to attack convoys and from 16 to 18, decimated a convoy by sinking 8 freighters and a destroyer, another badly damaged.

In November, Brummer successfully carried out another raid from Helgoland. In June 1918, she was seen performing two more minelaying missions, but remained inactive until November. Bremse raided off Fisher Bank in December 1916, and had the opportunity to use her AA to protect Zeppelin L44 from British fighters in September 1917. She also went out against merchant traffic, and carried out a raid on the coasts of Norway in April 1918. Like Brummer, she was forced to join Scapa Flow after the capitulation and scuttled there in June 1919.

In 1914, AG Vulcan in Stettin was building two sets of high-powered steam turbines for the Russian Navy, intended for the battlecruiser Navarin under construction in Russia. However August 1914 had the German government seizing the turbines. Meanwhile, the Kaiserliche Marine’s only two minelayer cruisers Nautilus and Albatross being whoefully unsufficient, ordered AG Vulcan to reuse Navarin’s turbines and from there, deliver two cruiser hulls buikt around these in order to be fast mine-layers for night operations of the British coast. The speed allowed them to make a “hit and run” minelaying opetration and not to be intercepted. Also it was envisioned to make them look superficially as the British Arethusa-class cruisers to confused British observers and allow them to close on the hostile coast.

Final Design and construction

Design work was completed in 1914, just after the order, SMS Brummer being laid down at AG Vulcan, Stettin in early 1915, built in record-time to be launched on 11 December. SMS Bremse was also built at AG Vulcan, but launched later, on 11 March 1916 and still completed in less than four months to be commissioned in mid-1916. To reach the same crescent bow shape (straight in German cruisers) and general silhouette of British cruisers the yard went as far as covering parts and add fake volumes using sheet metal for a perfect disguise.

Brummer was contract name “C” laid down at the AG Vulcan shipyard in Stettin in 1915. She was launched on 11 December 1915, after which fitting-out work commenced. Completed in less than four months. SMS Bremse was ordered under the contract name “D”, laid down also at AG Vulcan shipyard the same day but launched on 11 March 1916, followed by an express fitting-out work, also in four months for a commission on 1st July 1916, one month after Jutland.

Hull

blueprint

Both Brummer and Bremse were 135 meters (442 ft 11 in) long at the waterline, mostly due to the space required for the turbines, around which the rest of the ships were designed. They reached 140.4 m (460 ft 8 in) overall for 13.2 m (43 ft 4 in) in beam (making for a 1/10 ratio) and 6 m (19 ft 8 in) draft forward, down to 5.88 m (19 ft 3 in) aft. Designed displacement was 4,385 metric tons (4,316 long tons) standard and up to 5,856 t (5,764 long tons) when battle ready and fully loaded.

Construction of the the hull called for longitudinal steel frames and a waterline internal compartimentation pushed into twenty-one watertight compartments. They also had a double bottom for 44% pf the hull underbelly, over the keel. SMS Brummer was given portholes amidships, but not Bremse, and this was their first difference.

For the silhouette, both were given masts shaped like and implanted as on the British Arethusa-class cruisers, and they could be lowered and stored on the superstructure deck to free some fire arc or steam under bridges if necessary. The bow was modeled too as an Arethusa class bow, using extra plating to reach the desired shape. They carried both some 16 officers and 293 ratings and had the usual fleet of smaller service boats installed aft at the foot of the mainmast, served by a boom, and on davits along the main deck: She carried a steam picket boat, a barge for supplies, and two dinghies.

Powerplant

sea trials

The Brummer’s propulsion systems rested on these two turbines, rather powerful for cruisers. They drove two three-bladed screw propellers 3.20 m (10 ft 6 in) in diameter. These turbines in turn were fed by six mixed firing boilers: by just two coal-fired Marine Doppelkessel double-ended water-tube boilers, but also four oil-fired Öl-Marine double-ended boilers. Total output was rated for 33,000 shaft horsepower (25,000 kW), enough for a top speed of 28 knots (52 km/h; 32 mph). Thus was equivalent to the Arethusa class.

On trials however, Brummer with forced heating reached 42,797 shp (31,914 kW) for 30.2 knots (55.9 km/h; 34.8 mph) and even 47,748 shp (35,606 kW) for SMS Bremse, which was also observed capable of reaching 34 knots (63 km/h; 39 mph) in quick runs, something no British criser was capable of at the time.

They carried 300 t of coal as designed in peacetime, which could be doubled to 600 t in wartime, notably by filling extra waterline compartments. They also carried 500 tons of Fuel oil and also by having all voids filled, could reach 1,000 t. At a cruising speed (12 knots or 22 km/h/14 mph, they reached 5,800 nautical miles (10,700 km; 6,700 mi). When fast-cruising at 25 kn (46 km/h; 29 mph) this naturally fell to 1,200 nmi (2,200 km; 1,400 mi). Electrical power aboard came from two Siemens turbo generators coupled with a MAN diesel generator.

There was a single, large rudder and it was enough for them to be regarded as excellent sea boats, very agile, and with gentle and predictable motion making them good gun platforms. They had a tight turning radius and bled speed in heavy weather or about 60% speed when turning hard. They were also seen a bit stiff as well.

Protection, Armour scheme

Their protection tested on Krupp cemented steel. There were the following:

  • A Full waterline armored belt that 40 mm (1.6 in) in thickness amidships
  • The bow and stern were completely unarmored.
  • The armored deck at waterline level was just 15 mm (0.59 in) thick.
  • There was no extra armor over the steering gear room or ammunition magazines.
  • The main gun shields were made of 50 mm (2 in) plating.
  • The conning tower had 100 mm (3.9 in) walls and topped by a 20 mm (0.79 in) roof.
  • The bridge above was unarmoured except a splinter-proof chart house.
  • The three funnels had a steel glacis for splinter protection.

Armament

Compared to the Arethusa class it was weak, although they had four guns, the latter had two, but also six quicker guns. The 88 cm were a match for the 4-in (102 mm) at close range though, but they were there for AA defence mainly. Overall, aside their minelating capability they were rather weak for their size and tonnage.

-Four 15 cm (5.9 in) SK L/45 guns in pedestal mounts allowing 30° elevation, centerline, enabling a four guns broadside. They were located on the forecastle, between the first and second funnel and superfiring pair aft. 45.3-kilogram (100 lb) shell at 840 meters per second (2,800 ft/s) and max 17,600 m (57,742 ft 9 in). 600 rounds were carried (150 per gun), of HE/AP types.

-Two 8.8 cm (3.5 in) SK L/45 anti-aircraft guns, centerline, astern of the funnels. They fired a 10 kg (22 lb) HE shell at 750 to 770 m/s (2,500 to 2,500 ft/s).

-Two 50 cm (19.7 in) torpedo tubes (four torpedoes in reserve) in swivel mount amidships. G7 type (1913), 430 lbs. (195 kg) WH at 4,370 yards/37 knots or 10,170 yards/27 knots.

-450 mines on two main deck rails and stern chutes. They were moored Hertz horn contact mines Type I-IV with various warheads and depht settings. The more common Type IV was 34 inches (86 cm) in diameter, 620 lbs. (281 kg) and fitted with a 180 lbs. (81.6 kg) Wet gun guncotton warhead. Read more on navweaps

General Assessment of the Brummer class

After commissioning with the High Seas Fleet they made a sortie in the North Sea in October 1916, and mining Norderney approaches in January 1917 as well as covering minesweeping operations until May 1916. By October 1917 they were part of the attack force of a British convoy to Norway. They were chosen by Scheer because of their high speed and autonomy. The battle of Lerwick saw them butchering the two escort destroyers and sink nine of the twelve cargo vessels of the convoy, the rest beong damaged but escaping.

This infuriated the British Admiralty when leaent and remobilized the fleet to better protect these and change their communication habits and planning. These were the shining points of their career, the rest was les glamorous. Still, the Navy had immense respect for both cruisers, largely due to their oversized propulsion. If their design was generaly excellent, making them among the best German cruisers, their armament was weak, if only in a cruiser duel. It was perfectly adequate to rampage convoys as seen.

All in all, these cruisers were several fold better than the previous Albatros, but they really had the occasion of testing their metal against equivalent ships. In that case, they lacked armament: Four 15 cm guns versus eight of the Wiesbaden class, built at the same time. They still were by far the best minelaying cruisers of the central Empire, and their concept was sound.

Due to their reputation, the entente powers obliged to cede them Brummer and Bremse for internment at Scapa Flow. Departing on 21 November 1918 under Ludwig von Reuter, they were scuttled like the rest of the fleet on 21 June 1919, at 13:05, never raised for scrapping and remains to this day on the bottom. Bremse sank at 14:30. She was however raised on 27 November 1929 and BU 1932–1933.

The Wiesbaden class in comparison (1915-16) packed a twice greater punch.

Kaiserliche Marine SMS Brummer

brummr underway

SMS Brummer was commissioned into the Hochessflotte (High Seas Fleet) on 2 April 1916 and trained enough to be ready in early May 1916, but on the 31 she did not followed the fleet to Jutland and went on training. It’s only in the autumn of 1917, almost one year later, that Admiral Reinhard Scheer decided to start a new tactic, sending surface raiders ti catch and destroy British convoys to Scandinavia. He wanted to divert escorts from the Atlantic to give more leeway to U-boats.

SMS Brummer at the time un command of Fregattenkapitän Leonhardi teamed with SMS Bremse again (Fregattenkapitän Westerkamp) chosen by Scheer and prepared for this operation. In addition to their performances, they looed like British light cruisers, and the captains in addition knew Royal Navy communication codes. The crews also painted the ships dark gray, the livery of these cruisers in the Royal Navy a the time. Nothing was left unanswered for a perfect deceiption plan.

fwd section

Just after dawn on 17 October, SMS Brummer and Bremse arrived at cruise speed at a point which crossed the path of a westbound convoy 70 nautical miles (130 km; 81 mi) east of Lerwick. Hence later the “battle of Lerwick”. The convoy comprised twelve freighters escorted by the destroyers HMS Strongbow and HMS Mary Rose plus two armed trawlers. This seems to use ludrcrously weak, but at the time, convoy attack was only threatened by rare submersibles. Never the navy sent two surface cruisers for the task.

The German ruse worked enough for them to close in the convoy after a few exchanges by morse projector, reassuring the convoy commander about these to be friendly ships. Identification was not help by the way due to the early morning light. Recognition signals in rerturn from British vessels were however unanswered until the Germans eventually opened fire at a 2,700 m (8,900 ft), not point-blank range but close enough to almost guarantee first hits.

HMS Strongbow was hit by a first volley of both cruisers, eight 15 cm shells, which quickly were fatal, while Mary Rose closed in and by rapid fire, struggling to bring her to torpedo range, she was also dealt with. The two trawlers were armed with a single 3-in gun each and tried to protect the convoy the best theyr could, but now that the two shepherd dogs were out, the sheeps were ready for the slaughter. Bummer and Bremse rampeged into the convoy, even ifiring their 8,8 cm and torpedoes.

Recoignising the situation was hopeless, the two trawlers escaped with three merchant ships but the rest of the convoy was sunk entirely, nine vessels total, destroyers not included. Elise, one of the armed trawker coming from Bergen was fired on by Bremse while attempting to pick up survivors, something which was later told to the press and further exacerbate the ire of the admiralty. No wireless report was sent, wheras there was a squadron of sixteen light cruisers at sea, just south of the convoy. When known later, it was too late and Admiral David Beatty later said this was ‘luck was against us.’.

The British Admiralty was not informed of the attack the two cruisers informed the admiralty of their success while underway back home, and the message interecpted and decoded. Kaiser Wilhelm II congratulated the captains and Scheer for the idea and was overjoyed. The plan succeed as now, feating further raids, the RN decided to bolster the protection of its convoys with more vessels. But scheer, to maintain this fear, attempted more bold attacks all along the remainder of 1917 and 1918. None however achieved the same success.

Anyway, this feat, combined to the early successed for some far east cruisers like Emden, convinced the admiralty, of which any officers still crewed the Kriegsmarine years later, that commerce rauiding by cruisers and even battleships was a sound tactic for the new surface fleet. This was number one tactic to be applied by Erich Raeder, alongside a repeat of submarine warfare.

In late 1918, the Admiralstab again considered sending Brummer and Bremse on such mission, but in the Atlantic , where convoys were larger, and transiting to operate off the Azores with a pre-positioned oiler. They targeted the central Atlantic, out of U-boats. They were lightly defended on this leg and area. But eventually it was canceled as there was still some need to refuel them at sea, a dangerous task. If the oilers were spotted and sunk, the two cruisers would have been stranded there, easy targets fopr the entente;

Another issue identified was the clouds of red sparks emergig from their stacks when steaming over 20 kn (37 km/h; 23 mph), making them easy to spot by night, precluding a stealthy approach. SMS Brummer was also mobilized for thefinal sortie “for honor” of the High Seas Fleet in October 1918, cancelled due to mutinies in Wilhelmshaven. She was moved to Sassnitz; but due to their reputation, both were included in list of internment in Scapa Flow signified to the Admiralstab.

Brummer followed on 21 November 1918 the rest of the Hochseeflotte as part of a single file, heavily guarded by an international coaslition. Under RADM Ludwig von Reuter she arrived in the Firth of Forth later this day and escorted to their final leg into Scapa Flow. Wireless equipment was removed as well as breech blocks for the heavy guns and skeleton crews only for basic maintenance, the rest being sent home. Further crews cuts were made by Reuter fearing an uprising on board.

Unaware that the new extended deadline provided on 23rd, Reuter wated for the Home fleet to depart for exercizes and ordered this morning of 21 June, her order the crew to prepare the ship, so at 11:20 order was given for a scuttling, using mostly pumps or small explisive charges in the underbelly not to raise attention. Brummer sank at 13:05, never raised, still there under 36 m (118 ft), a nice recreational site for scuba divers.

Kaiserliche Marine SMS Bremse

SMS Bremse was commissioned on 1 July 1916, and on 11–20 October she teamed with her sister Brummer for a first sortie in the North Sea. This was mostly a patrol, which was uneventful. On 10 January 1917, however, they woukd be used as intended, although in a mission not as bold as initially planned. They would lay a minefield off Norderney (Nördernee, an East Frisian Island off the North Sea coast of Germany). This was a defensive minelfield, certainly not an offensive one, close to the british coast. Together they laid around 900 mines.

On 1–13 March, they escorted minesweepers from Emden and Wilhelmshaven. The rest of 1917 saw no important mission but in October 1917 an important commerce raiding mission to diver the RN atttn,tion from submersible warfare in the Atlantic. At the time, Britain agreed to ship 250,000 tons of coal monthly to Norway in exchange of steel. These convoys started to cross the North Sea by late 1917 and were weakly escorted as consiered too far away for German raiders.

Scheer until then posted U-Boats along their supposed route, but in vain. Her wanted to try a dailight surface surprise raid and mobilized Bremse (Fregattenkapitän Westerkamp) and her sister Brummer for the task, being the longest-range, faster cruisers designed to resemble British light cruisers. All measures were taken for a perfect deceiption, and both cruisers as described above, arrived to the scene as planned at dawn on 17 October and the rampage was total.


Bremse during the Lerwick convoy attack in 1917 (shipbucket)

Brummer and Bremse were mobilized again for a commerce raiding mission into the Atlantic, based off the Azores and replenished at sea by an oiler to operate in the central Atlantic, where convoyed expecting no threats, were lightly defended. This (the limited radius of U-Boats) was recoignised in interwar and Dönitz would precisely specify a range extending to the central Atlantic which becalme in WW2 the famous “black pit” with limited escort and air cover.

The Admiralstab however canceled the plan due to several issues. On 2 April 1918 however, SMS Bremse, sent alone, laid a 304 mines field in the North Sea, and 150 on 11 April. Both made a final fleet sortie with the rest of the battle fleet on 22–24 April, in vain as they spotted no British vessel. On 11 May, SMS Bremse laid another minefield in the North Sea, with her almost full load of 400 mines and 420 mines on the 14th. Mobilized for the final sortie of the High Seas Fleet in October, it was cancelled due to mutinies.

Included in the list for internment she departed on 21 November 1918, being later rescorted on the RDV point by some 370 entente warships to the Firth of Forth and later Scapa Flow. Wireless was removed as her 15 cm guns breech blocks while part of her crew was sent back home. In June 1919, Von Reuter believed the deadline was about to expire on the 23 and prepared the scuttling, waiting for an opportunity to proceed. On 21 June, the departure of the British fleet for training maneuvers gave just the pretext he wanted and ordered at 11:20 the general scuttling order. It was done with celerity as all preparations has been made long ago in such eventuality.

Seeing Bremse prepared for the scuttling, an armed British naval party attempted to board her and close her bottom valves, but they arrived too late. They managed instead to blast off her anchor chains to have her taken in tow under guard from the destroyer HMS Venetia, trying to beach her. Indeed they managed to have her beach south of Cava, bu the slope here was such that her stern sank deep, so she rolled over and sank in 75 ft (23 m) of water at 14:30. Fortunately there was no casualty. Her bow emerging there was the only reminder for many mon,ths and years afterwards.

Ernest Cox bought salvage rights in the early 1920s but Bremse presented her own challenges. She was in part perched precariously on a sloping rock and could during salvage operations slip off and sinkat any moment, so Cox’s salvage team sealed her bulkheads, divided the hull into watertight compartments and pumped air in them, afetr the hull was patched up and fitted with an airlock. There was however still a load of oil covering her which needed disposal. With oxyacetylene torches, some was burnt, leading to an explosion, but none was injured.

By July 1929 superstructure being gone, she was turned upside down and compressors brought her to the surface, supported by 9-inch wires connected to the floating docks anchored on her port. However as success was coming, she toppled onto her side, heeled over and settled onto the rocks inshore, also causing an oil spill. It was decided to burn off the oil and the fire was later controilled while operations resumed, patching her again, pumping in air, and she again broke the surface. Considered too unsafe to tow to Rosyth she was brought to nearby Lyness on 30 November to be scrapped. So she outlived here sister by eleven years.

Pillau class cruisers (1914)

Pillau class cruisers (1914)

Germany (1914): SMS Pillau, Elbing

From Russia, with Love

The Pillau class were originally the Russian-ordered Maraviev Amurskyy and Admiral Nevelskoy, in 1912 to Schichau Yards. They were laid down in 1913 and launched for the first on 11 April 1914. Therefore on 5 August, both were requisitioned and completed as SMS Pillau and Elbing. They were a bit singular in their style, and their career as well. The first Took part in the battle of Riga, Jutland, Heligoland Bight (2), and became the Italian Bari after the war, modernized and sunk in Livorno by the RAF in June 1943. Elbing on her side took part in the Yarmouth raid, but was lost during the battle of Jutland, not due to enemy action but when she was rammed by SMS Posen…

Design context and construction


Design of the original Amurskyy class. Notice the conning tower with almost no bridge, three equal funnels, and different armament with the rear ones placed on a superstructure, the side ones on sponsons.

Specifics of the Amurskyy class training/minelaying cruisers

In 1912, the Imperial Russian Navy badly needed new cruiusers fast to rebuilt her crippling losses after the Russo-Japanese war. For memory she lost both her pacific squadron and baltic fleet. Russian yards were alrady busy with some priority construction, in particular dreadnoughts, so the admiralty contacted builders for a pair of light cruisers, and eventually Schichau-Werke, Danzig, won the contract. The Maraviev Amurskyy class were small turbine cruisers planned to acquire as part of a four cruisers procurement, with a design of light cruisers displacing 6800 tons for the Baltic, and 7600 tons for the Black Sea.

There was acute debate about the use of turbine, due to the total lack of training for the crews to service these on new ships. Therefore, the two small cruisers included in the new shipbuilding program were supposed to be turbine training ships. The Naval General Staff considered this task to be prioritary, and also to replace the obsolete Askold and Zhemchug stationed the Far East, now part of the new “Siberian military flotilla”. The third objective was to have them acting optionally as high-speed minelayers, carrying more mines than destroyers, agility and improved maneuverability.

It was planned to reach the agility requirement by a limited length of no more than 130 m and a refined hull shape, although this could adversely impact propulsion. In 1912, the General Directorate of Shipbuilding sent a request for proposals to several yards, Ansaldo, Shichau and Vulkan, pressed to take part in a competition. On the recommendation of the MGSH, two guns were placed on the forecastle, two in casemate bow, two in the aft superstructure and two on the poop.

Experts believed this placement would significantly increase their chase and retreat firepower, and make room for mine rails. Four anti-aircraft guns also were needed to be place as not to interfere with the main artillery still have the best arc of fire possible. Since the displacement was not indicated in the specifications, all projects submitted largely differed on that plan: Putilov submitted a 4,000 tons cruiser, Nevsky 3,800 tons, Revelsky 3,500 tons, Vulkan 4,600 tons and Schichau 4,000 tons. Note that Ansaldo did not even aswered.

As the project was further developed in order to reach agreement to discussions between the MGSH and GUK, the displacement gradually increased while speed decreased and in the end, the Schichau project and its 27.5 knot speed, based on the Kolberg-class cruisers appeared the quickest and most proven of all. But the Naval Ministry was still not satisfied with the traditional German three-shaft configuration, nor their boilers of a type not used in the Russian fleet. It also underlined weak structural basis for the guns and insufficient height above the waterline. Schichau promptly reworked the project and resubmitted it after fixing all issues.

Meanwhile, Nevsky Yard was nevertheless recognized as the winner of the competition, but on auction the bidder, fastest construction time were from Schichau, and having considered all applications, the Naval Ministry eventually gave preference to Dantzig Yard, receiving a signed order on July 15, 1914, and a second four months later. Other factories were just not ready to start construction immediately. Putilov shipyard and Revel were already full with orders to manufacturer shells and supplies, while the Nevsky plant could hardly cope with the construction of two destroyers for the Black Sea already.

Giving preference to the Schichau represented a risk however at a time of great turmoil and increasing tensions in the Balkans. Representatives of the General Staff were not even consulted and were faced with a fait accompli, the ministry’s GUK explaining their choice based mostly on the construction time due to a proposal of a slightly modernized SMS Mainz for which plans were drawn already with little modifications. In addition, the yard recommended ten Yarrow boilers (6 coal-burning, 4-oil burning) to feed their own turbines, plus the same propellers as on SMS Karlsruhe.

Both turbines had a capacity of 28,000 liters and the design speed of 27.5 knots (51 km/h) was estimated easy to reach. In January 1913, the named of Muravyov-Amursky and Nevelskoy were reviewed and eventually accepted, for a launch by late 1914, while negotiations were underway between Russia and England for the finalization of the Triple Entente. Of course, by August 1, 1914, war broke out between Germany and Russia leading straight to a requisition and both cruisers changed ownership and later names, on August 6.

Requisition and completion as the Pillau class

As the war broke out in August 1914, both cruisers were in construction in their basins. The first was launched on 11 April 1914 already and completion was on its way, until stopped by the navy command for standardizattion after the requisition. Plans were changed and modifications made until she was completed and eventually Commissioned 14 December 1914 under the new name of S.M.S Elbing from the baltic port. Her sister ship was launched later, on 21 November 1914 as SMS Elbing. Time was gained since moidifications has been done to her sister so she could be converted and standardized right away. She was commissioned into the High Seas Fleet on 4 September 1915.

Detailed design

Blueprint of Bari
Blueprint of Bari, which presented some significant differences with Pillau

Both vessels had both a family air of German and Russian cruisers strangely. Moslty German, with their three funnels, general forecastle and hull lines, straight prow, and some Russian aspects for the bridge and masts as well as casemates. They were manned by a complement of twenty-one officers, leading 421 ratings. Like all the others they had a fleet of smaller boats: Steam picket boat, one supply barge, two rowing yawls and two dinghies.

Hull construction and general design

The Pillau class hull ended as 134.30 meters (440 ft 7 in) long at the waterline, 135.30 m (443 ft 11 in) overall, with a beam of 13.60 m (44 ft 7 in) and draft of 5.98 m (19 ft 7 in) forward, 5.31 m (17 ft 5 in) aft. Nominal calculated displacement of 4,390 metric tons (4,320 long tons) standard as designed reached 5,252 t (5,169 long tons) when fully loaded. They were not particularly overweight. Construction called for transverse and longitudinal steel frames and below the waterline, it was subdivided into sixteen watertight compartments, and completed by a double bottom extending for 51% of the total jull length.

Armor protection


Pillau in port

The Russian Navy imposed changes specific to them in the design, notably getting rid of a waterline armored belt. Instead, they had an armored deck 80 mm (3.1 in) thick in the central section, up to the bow, but tapering down to 20 mm (0.79 in) aft. It was sloped with a layer of 40 mm (1.6 in) on either side on the upper portion of the sides by default of a belt. Main battery guns had 50 mm shields. Conning tower received 75 mm (3 in) thick walls, completed by a 50 mm (2 in) rooftop. That was it. It was design to somewhat resists destroyer fire but not much, and the ASW compartimentation to delay a sinking. Speed was the actual, active protection.

Powerplant & Performances

The propulsion system comprised as said above, two sets of (German Admiralty) Marine steam turbines. They drove two 3.5-meter (11 ft) bronze propellers. Steam camle also froma mix of six coal-fired Yarrow water-tube boilers, and four oil-fired boilers fromp the same manufacturer. They were trunked into three funnels on the centerline. Fortunately for them, the Germans ordered these boilers soon enough.

Performance-wise, these were rated for 30,000 shaft horsepower (22,400 kW) total, in order to reach of top speed of 27.5 knots (50.9 km/h; 31.6 mph). For range, they carried each some 620 t (610 long tons) of coal, plus 580 t (570 long tons) of oil for a grand total of 4,300 nautical miles (8,000 km; 4,900 mi) at the cruise speed of 12 knots (22 km/h; 14 mph), roughly half their top speed. For onboard elecvtrical power, they counted of three German Siemens turbo-generators for a total output rated at 360 kilowatts (480 hp), based on standard 220 Volts.

In general they were considered good sea boats, although fairly stiff. They suffered from heavy roll, though with a relatively predictable motion as gun platforms. They were considered maneuverable, just responsive at the helm, but slow in turns and bleeding speed fast hard rudder, up to 60%. Steering by the way depended on a single large rudder. In a head sea they also lost speed, as expected, not in sync with the wavelenght.

Armament

As designed, they were planned with eight 130 mm (5.1 in) Russian L/55 QF guns plus four 6.3 cm (2.5 in) L/38 guns from Obukhoff. However as completed for the Riechsmarine, this planned armament was standardized. Here is the detail. Specs are similar to other German cruiser’s guns, albeit they were the first German cruisers planned to mount 15 cm guns right away:
The 15 cm (5.9 in) SK L/45 guns in single pedestal mounts were side by side on the forecastle, four amidships and two side by side aft. Range of 17,600 m (19,200 yd), 1,024 rounds provided total. The four 52 mm AA were replaced later by two largely better 8.8 cm (3.5 in) SK L/45 AA guns. Theytwo torpeod tubes were mounted on deck. The 120 mines were carried on two long rails along the main deck, starting immediately aft of the forecastle.

  • Eight 10.5 cm (4.1 in) SK L/45 guns
  • Four 5.2 cm (2 in) SK L/55 anti-aircraft guns
  • Two 50 cm (19.7 in) torpedo tubes
  • 120 mines

SMS Pillau damaged

WW1 service

SMS Pillau was commissioned on 14 December 1914, trained until assigned to II Scouting Group. She was first sent in the Baltic to take part in the Battle of the Gulf of Riga in August 1915. She screen a force of eight dreadnoughts and three battlecruisers, but on 13 August, Russian submarines ambushed her. Three torpedoes were coming her way, but missed. Pillau was in the second attack on 16 August and when minesweepers cleared the minefields on the 20th, she entered the Gulf, to withdrawn to Moon Sound again due to Russian submarines and mines. She was back in the north sea station by August.

Although she took part in several sweeps afterwards, nothing was of note until May 1916. Like her sister ship she was prepared for a major operation as part of the II Scouting Group, screening for the I Scouting Group, leaving on 31 May for the Skagerrak and at 15:30, Pillau and Frankfurt assisted Elbing, engaging the Britush criser screen, at 16:12 PM firing on HMS Galatea and Phaeton from 16,300 yards (14,900 m) and ceasing at 16:17 due to the range. 15 minutes later they spotted and engaged the seaplane tender HMS Engadine and afterwards were back on stations.

At around 16:50, the British 5th Battle Squadron spotted Pillau, Elbing, and Frankfurt, HMS Warspite and Valiant opening fire first at Pillau at 17,000 yards (16,000 m). She was straddled with almost near-misses, so decision was mlade to lay smoke and hide their escape at high speed. An hour later, German battlecruisers were charged by the destroyers HMS Onslow and Moresby and Pillau, Frankfurt drove them off with rapid fire. At 18:30, Pillau spotted HMS Chester and and scored several hits before disengaging due to the arrival of Rear Admiral Horace Hood’s Invincible class battlecruisers.

HMS Inflexible scored a hit on Pillau, with a 12 in (300 mm) shell which exploded below her chart house; although fortunately the blast went overboard. Due however to her starboard air supply shaft, the explosion blast was also vented into second boiler room which shut all six coal-fired boilers. She managed to maintain 24 kn (44 km/h; 28 mph) using only her four remaining oil-fired boilers and escaping in heavy fog. By 20:30, three boilers were back in operation so she was now steaming at 26 kn (48 km/h; 30 mph) out of harm.

And then came the night battle: The Britsh were closing their trap and at 21:20, the II Scouting Group met British battlecruisers, turning away, and while doing so, Pillau came under fire from them, but not close. HMS Lion and Tiger in all fired salvos at her without result before turning on SMS Derfflinger, and as reported by Pillau they were “very inaccurate”. Pillau and Frankfurt then spotted the cruiser HMS Castor leading several destroyers at 23:00, fired their torpedoes and turned back toward the German lines, keeping their searchlights off not to draw attention.

By 04:00 PM, the fleet managed to reach Horns Reef. At 09:30, Pillau was detached to assist SMS Seydlitz, still far from port. Pillau steamed ahead of her, guideing her to Wilhelmshaven until she however ran aground at 10:00 off Sylt. She was freedat 10:30 and could resume her voyage with Pillau and soon a division of minesweepers testing depth while screening them. Pillau ttempted to tow the battlecruiser but the hard strained line repeatedly snapped. Pumping steamers were there in the evening to help, Pillau guiding them until reaching the outer Jade lightship at 08:30. In all she had fired 113 main rounds, four 8.8 cm shells and a torpedo, with 4 killed, 23 wounded.

Her sister ship was rammed and sunk during the engagement leaving her the sold survivor of her class. Northing much happened until July 1917, whe she saw a mutiny aboard while in Wilhelmshaven. The 20th, 137 men left the ship to protest a cancellation of their leave, spent hours in the town and then returned to resume their tasks as a show of good will. But Pillau’s captain’s retribution was light, with only limited punishment. By late 1917, she was reassigned to the IV Scouting Group with SMS Stralsund and Regensburg.

By late October 1917 they were tasked to replace heavy units of the fleet after Operation Albion in the Gulf of Riga, with battleships of the I Battle Squadron. The operation was cancelled anyway due to the danger of mines and submarines. She wazs back to the North Sea on 31 October and the II Scouting Group.

On 17 November, they screened the battleships Kaiser and Kaiserin, which themselves cover minesweepers in the North Sea. British cruisers supported by battlecruisers and battleships arrived, which trigerred the Second Battle of Heligoland Bight. Königsberg (ii), Pillau’s group flagship, was damaged while the four cruisers evaded the trap but also draw them toward the German dreadnoughts. Both sides exhanges fire but eventually parted away, Pillau being unscathed.

On 23–24 April 1918, she was mobilized for an abortive fleet operation to Norway, as the Germans failed to locate the convoy, Scheer breaking off the operation. By October 1918 with the II Scouting Group she wa smobilized for the final attack planned in force, and Pillau, Cöln, Dresden, Königsberg(ii) were intended to lead a diversionary, drawing attack on merchant shipping directly n the Thames estuary. Karlsruhe, Nürnberg, Graudenz were to be sent to Flanders to draw out the British Grand Fleet. But on 29 October 1918, order to sail from Wilhelmshaven were met with wholesale mutiny forcing cancellation. Pending her fate, SMS Pillau was anchored in Germany, exlcuded for the fleet going to Scapa Flow for internement in 1918.

Italian service as Bari (1920-1943)

Bari-Venice
Bari in Venice during the interwar

Although she was listed in the Reichmarine, Pillau was stricken on 5 November 1919, surrendered to the Allies in Cherbourg on 20 July 1920 peing attribution. She was ceded to Italy as a war prize. As Bari, modified, she was recommissioned into the Regia Marina on 21 January 1924, as fleet scout (Esploratori). Her German AA guns were replaced with Italian 76 mm (3 in)/40 guns. In August 1925 she ran aground off Palermo. By July 1929, she joined Ancona and Taranto, Premuda as the Scout Division, 1st Squadron in La Spezia.

Modernized in the early 1930s (bridge, forward funnel) she was refitted for colonial service, witll all oil-firing boilers and additional oil bunker space. She lost her forward funnel, having the others cut cut down. Now based on 21,000 shp (16,000 kW) for 24.5 kn she reached 4,000 nmi (7,400 km; 4,600 mi) at 15 knots. She was deployed in the Red Sea and Italian East Africa until May 1938, relieved by the sloop Eritrea, ad by the start iof WW2, received six Breda 20 mm (0.79 in) and six 13.2 mm (0.52 in) HMGs.

In 1940 she became flagship of the Forza Navale Speciale taking part in the Greco-Italian War and covering the the invasion of Cephalonia and mainland Greece. From April 1941 and Greece defeat, she escorted convoys to Greek ports for occupation, but war with France in June 1940 saw her mobilized on the west coast until the capitulation of the latter. In 1942, the invasion of Malta was planned and Bari, Taranto were to cover the landing force. It was cancelled.

In November 1942 she became the flagship of the amphibious force landing at Bastia, French Corsica. Later she shell partisans off the Montenegrin coast, based in Livorno. Eventually placed in reserve in January 1943 the admirakty envisioned her conversion as AA ship (with six 90 mm/50 guns, eight 37 mmguns, eight 20 mm/65/70) but by 28 June it was stil not started when an US air raid devastated Livorno and badly damaged Bari. In September 1943, she was scuttled to avoid falling into German occupiers’s hands. The latter scrapped her partially in 1944. Stricken on 27 February 1947, she was raised on 13 January 1948 and BU.

Kaiserliche Marine SMS Elbing


Postcard of SMS Elbing

SMS Elbing after some initial training was assigned to II Scouting Group, screening for Rear Admiral Friedrich Boedicker’s battlecruisers of I Scouting Group. She sailed away of them with destroyers for the raid on Yarmouth and Lowestoft on 24–25 April. While approaching Lowestoft, Elbing and Rostock both spotted the incoming Harwich Force (three light cruisers, 18 destroyers) from the south at 04:50. RADM Boedicker initially ordered the battlecruisers to continue while Elbing and five other light cruisers went to to fight off the Harwich Force.

At 05:30, the clash commenced at long range, and weent on wih little scores on each sides and perhaps caution, until the battlecruisers arrived at 05:47. At their sight, the British squadron quickly retreated. The overall result was a light cruiser and a destroyer both damaged. Boedicker did not chased them and broke off after receiving reports of British submarines closeby.

After several months of relative quiet service and few screening sorties without anything noticeable, she was in May 1916 under orders of Admiral Reinhard Scheer for a major operation. She served with the II Scouting Group attached to I Scouting Group, leaving the Jade at 02:00 on 31 May. After heading for the Skagerrak an hour and a half later before the main leet, her lookouts signalled at 15:00 the Danish steamer N. J. Fjord and she detached two torpedo boats to investigate.

Meanwhile HMS Galatea and Phaeton arrived to inspect the steamer, and fired on them at circa 15:30. SMS Elbing then turned to cover them and opened fire at 15:32, scoring the very first “hit” (turned out to be a dud) of the battle on HMS Galatea. The cruusers then turned north toward the 1st Battlecruiser Squadron chased by Elbing, still firing, and soon joined by SMS Frankfurt and her sister Pillau but they stopped at 16:17, out of range. They later spotted and engaged briefly the seaplane tender HMS Engadine, failed to score any hits and later returned to their screening stations.

At around 18:30, SMS Elbing encountered the cruiser HMS Chester and she opened fire, scoring several hits to later disengaged as RADM Horace Hood’s battlecruisers were spotted incoming. HMS Invincible actually scored a hit on SMS Wiesbaden, disabling while Elbing and Frankfurt fire their torpedoes at them, missing. Elbing was framed by water plumes while fleeing from the battlecruisers but labaged to keep the distance. At circa 20:15, Elbing’s suddent leakages in her boiler condensers had her slowing down to 20 kn (37 km/h; 23 mph) and she stayed at that regime during frantic repairs for four hours.

II Scouting Group meanwhile was ordered to take station ahead of the line ro take its night cruising formation. Elbing was unable to keep up and fell with IV Scouting Group. At 23:15, she teamed with SMS Hamburg when both spotted the British cruiser HMS Castor leading a pack of destroyers. Vleverly their captains used the British recognition signal when closing enough to engage them at 1,100 yards before turning on their searchlights. Bt night it was nigh-impossible to recoignise them.

The ruse worked and Castor was soon hit seven times and set on fire by both cruisers, and the British turned away in a panic, but not before the destroyers launched volleys of torpedoes at Elbing and Hamburg, whch manouevred hard to avoid them. One passed right underneath Elbing and failed to explode. The 2nd Light Cruiser Squadron also arrived, engaging IV Scouting Group and hit Elbing once, knowking out her wireless station with 4 killed, 12 wounded. Midnight arrived, and afterwards, the British net was closing on the retreating Germans.

Elbing ran on a the rear British destroyer screen, steaming on the port side of the German line with Hamburg and Rostock when SMS Westfalen opened fire first quickly by Elbing, Nassau and Rheinland. A Brithsh torpedo attack forced the cruisers to turn to starboard, but this placed in the path of thee German line. Elbing just managed to pass between Nassau and Posen, but Posen’s captain was too late to realize the manoeuver and rammed the cruiser, after trying to turn hard to starboard. Her bow went stright to Elbing’s starboard quarter.

The cruiser was holed below the waterline, which flooded the starboard engine room first. She took a 18° list, soon counter-balanced eighteen but was dead in the water, with her engines flooded and shut down. Steam started to condense in the pipes and soon the electric generators went down, the ship loosing all lighting and power. With the pumps down, there was little hope to save her while flooding spreaded throughout the underwater compartments, somewhat reducing the list, but still nit in danger of sinking.

At 02:00 AM, Elbing was helped by the torpedo boat S53 which came alongside to take aboard 477 officers and men, her commander and a few officers remaining on board either to save or scuttle their ship. Amazingly, they rigged an improvised sail to try to bring the ship closer to shore. But their effort was for naught: At 03:00, British destroyers were spotted coming from the south. Before their arrived, order was given to scuttle the ship while the ship’s cutter was lowered and set off, steaming back to port. At around 07:00, a Dutch trawler met the cutter and took the men aboard, returned as POWs to Holland. In total during the battle, Elbing would had fired 230 main 15 cm rounds and a torpedo.

Graudenz class cruisers (1914)

Graudenz class cruisers (1915)

Germany (1912-1944) – SMS Graudenz, SMS Regensburg

The Graudenz class were another iteration over the now classic kight cruiser formular prioneered by the Brmen class in 1902. Tne years after a constant, complete improvement cycle (namely the Könisgberg (1905), Dresden (1907), Kolberg (1908), Magdeburg (1911) and Karlsruhe (1912), the admiralty came with a new design reaching almost 6,400 tonnes fully loaded, almost twice as much as the Bremens. And unlike the previous Karlsruhe, they reverted to three funnels and introduced 15 cm guns, better in tone with the new size of these vessels and to compete with the Royal Navy’s own light cruisers.

Gradeuz as French cruiser FS Strasbourg in the 1920s

SMS Graudenz and Regensburg, started in 1912, entered service in 1915, and both had a fairly long career unlike contemporary German cruisers; Graudenz saw extensive service in the reconnaissance screen for the I Scouting Group’s battlecruisers: Scarborough, Hartlepool, Whitby, Battle of Dogger Bank, Gulf of Riga until October 1918. They missed Jutland, the first being allocated as a war orize to Italy and partluy modernized, and SMS Regensburg saw the Battle of Jutland and served with the I Scouting Group battlecruisers. She was ceded to France in 1920, Strasbourg and used as a colonial cruiser, discared 1936, used as barracks ship and sunk in Lorient in 1944.

Design

The Graudenz class cruisers were slightly larger than the previous Karlsruhe class but with shorter hull at 139 meters (456 ft) waterline, 142.70 m (468 ft 2 in) overall. They had a larger beam of 13.80 m (45 ft 3 in), 60 cm more than the Karlsruhe, much hiher draft at 5.75 m (18 ft 10 in) forward, 6.08 m (19 ft 11 in) aft (versus 4.5 m on the Karsruhe).

Displacement with such figures was higher, at 4,912 metric tons (4,834 long tons), as designed, and reaching 6,382 t (6,281 long tons) fully load, versus 5,925 tonnes FL fr the previous cruisers. Construction called for the same conventional longitudinal steel frames, defining seventeen watertight compartments. There was also a double bottom on 47% of the keel.

Their crew was lightly less than the previous cruisers, with twenty-one officers and 364 enlisted men, far less than the 450 of the previous vessels. The better, more automated design perhaps, despite the same armament which perhaps contributed to this difference. As a whole, the ships were considered roomier. However, they were also fitted to be used as second command flagship (flotilla leader) with three officers and fourteen additional ratings. The onboard small boats fleet including a single steam-powered picket boat, a supply barge, a cutter, two yawls, and two dinghies.

Powerplant

Their propulsion system comprised two sets of Marine-type steam turbines, connected to shafts ended by two bronze-cast three-bladed 3.50 m (11 ft 6 in) diameter propellers. They were fed by twelve Marine water-tube boilers. For ASW protection, each turbine was separated inside its own engine room. As designed, they developed 26,000 shaft horsepower (19,000 kW). In a similar way, the twelve boilers, which were divided into ten coal-fired and two oil-fired and double-ended ones, were located also in four boiler rooms.

All in all, with the same output as their predecessors, they reached a top speed of 27.5 knots (50.9 km/h; 31.6 mph), less than the 29.5 as designed of their predecessors. For range, with 1,280 t of coal, and 375 t of fuel oil they reached circa 5,500 nautical miles (10,200 km; 6,300 mi) at the cruise speed of 12 knots (22 km/h; 14 mph). They could maintain 25 knots but in that case, it fell to 1,000 nmi (1,900 km; 1,200 mi), roughly comparable to the previous vessels.

As a complement, they also had two turbo generators plus a single diesel generator to power all onboard system when the powerplant was cold. They together reached the output of 260 kilowatts (350 hp), at 220 Volts.

At sea, reports said they were regarded as good sea boats, with slight weather helm, gentle, predictable motion in a swell. They were maneuverable, but due to their hull ratio, bleed speed in a turn, up to 60° with the rudder hard over. Steering depended on a single large rudder. Transverse metacentric height was .79 m (2 ft 7 in) and they were considered stable gun platfrom despite their heavier main guns after upgrade in 1916.

Armament


bp regensburg 1917 as rearmed

Twelve 10.5 cm (4.1 in) SK L/45 guns, single mounts. Two side by side on the forecastle, eight amidships, on both sides and including two in a superfiring pair aft.

  • Maximum elevation 30 degrees
  • Max range 12,700 m (13,900 yd)

-In 1916, they were all replaced by seven 15 cm (5.9 in) SK L/45 guns.

  • Maximum elevation 30 degrees
  • Max range 12,700 m (13,900 yd)

-There was nothing when completed beside these main guns, but two submerged 50 cm (19.7 in) torpedo tubes, with five torpedoes in reserve.


After their 1916-17 refits, they were given two 8.8 cm (3.5 in) SK L/45 anti-aircraft gun, while two extra deck-mounted torpedo tubes were added on Graudenz, while Regensburg had her submerged tubes removed, four deck mounted installed instead. Although on paper they had rails and the capacity to carry and lay 120 mines, this was not used.

Armour Protection

Nothing revolutionay in their protection scheme which was virtually a repeat of the previous cruisers. They were designed to stop same caliber shells (10,5 cm) and nothing more. In effect they were rearmed in 1916-17 with a caliber superior to their protection.

  • Waterline armored belt 60 mm (2.4 in) amidships, 18 mm (0.71 in) bow.
  • Armored deck 60 mm forward, 40 mm amidships, 20 mm (0.79 in) aft.
  • Sloped armor 40 mm to connect deck and belt.
  • Conning tower 100 mm (3.9 in) walls, 20 mm roof.
  • Rangefinder 30 mm (1.2 in).
  • Main battery gun shields 50 mm (2 in)

Construction

SMS Graudenz was ordered under the contract name “Ersatz Prinzess Wilhelm”. She laid down at the Kaiserliche Werft shipyard (Kiel) in 1912, launched on 25 October 1913, assisted and christened by the mayor of her namesake city, Dr. Kühnast. She was commissioned on 10 August 1914. The war was fresh of only 15 days.

SMS Regensburg was ordered as “Ersatz Irene”, laid down at the AG Weser shipyard (Bremen) at the same time, but launched much later on 25 April 1914. In assistance and chistening the vessel was the mayor of her namesake city, Hofrat Josef Bleyer. She was commissioned on 3 January 1915 to the High Seas Fleet and a lot already happened for the fleet in the meantime.

Kaiserliche Marine SMS Graudenz

SMS Graudenz 1915

SMS Graudenz’s was mobilized for the raid on Yarmouth, 3 November 1914 as part of the reconnaissance screen assigned to the battlecruisers of the 1st scouting group under orders of Rear Admiral Franz von Hipper. There in her unit were the cruisers SMS Kolberg and Strassburg.

The shelling done, the raiding fleet return, an uncharted German mine just utside Wilhelmshaven blasted open the hull of the armored cruiser SMS Yorck. This was fatal and she sank. Next, Graudenz took part in the same circumstances to the raid on Scarborough, Hartlepool and Whitby (15–16 December). However when withdrawing, British forces waited for them. Despite of this, with two squadrons closing, SMS Graudenz, Stralsund, Strassburg, leading their two flotillas of torpedo boats managed to pass through both squadrons.

However soon they crossed a heavy mist, and could not see beyond 4,000 yd (3,700 m) when it happened. SMS Stralsund was just spotted briefly and in fact this covered their withdrawal. Later, Graudenz screened the I Scouting Group for a Dogger Bank foray on 24 January 1915 and she was too distant to participate in the Battle of the same name.

In August 1915, SMS Graudenz was reassigned to the Baltic. The major operation there was to clear out the Gulf of Riga of Russian forces, and in this, no less than eight dreadnoughts and three battlecruisers were taken from the Hochseeflotte. Graudenz took part only in the second attack, on 16 August, with Nassau and Posen. Albeit the operation was a success, Graudenz struck a mine on the night of 21/22 April 1916.

Placed in drydock in May 1916 she missed the Battle of Jutland and at her return in active service, modernized and with a new armament, she was assigned her own torpedo boat flotilla, as leader. Nothing much happened in the remainder of 1916 or 1917 of note. The same was true in 1918, apart a few sorties, either of patrol or training.

By October 1918 however, Graudenz was assigned to the II Scouting Group, for the planned giant attack by whole the High Seas Fleet, “for honor”. More details specific she would have been part in a foray on Allied shipping right into the Thames estuary, and along Flanders in the hope to lure out the Grand Fleet.

For this, Graudenz, Karlsruhe and Nürnberg were mobilized to proceed to Flanders first, and prepared, but on the morning of 29 October 1918, order tp sail was given, but during the night disgruntled sailors on several battleships mutinied, forcing Hipper and Scheer to cancel it; Nevertheless, Commodore Andreas Michelsen convinced the general staff that smaller ships were in general more loyal, and to organize a “light force” headed by light cruisers. Even U-boats were to take ambush position on a probable withdrawal route. Graudenz became his flagship.

As it happened, this too, never materialized. The war ended, but she was not in the Hochseeflotte, so not part of the fleet which headed for internment in Scapa. Instead she served briefly in the Reichsmarinewas and was eventually attributed as a war prize after the Versailles treaty provisions in 1919, attributed to Italy.

For more on Ancona, her new Italian name, see the WW2 Italian cruiser’s page.

Kaiserliche Marine SMS Regensburg

Strasbourg 1920 ex Regensburg

SMS Regensburg completed her sea trials on 10 March 1915, after which she was assigned to the II Scouting Group in the baltic. There, she shelled Russian positions at Polangen and Papensee until 24 March, after which Captain Hans Zenker proposed to reaem her 15 cm guns (as the liner Cap Polonio) to start a commerce raiding campaign in the Atlantic to replaced the vessels lost in 1914. Admiral Friedrich von Ingenohl denied this request arguaing the Royal navy mastery of the north sea would have seen her sunk as well and don’t wanted to loss a modern light cruiser.

On 17–18 May, SMS Regensburg instead covered a mine-laying operation off the Dogger Bank. On 25 August she was back to the baltic for shore bombardment on Dagö island and St. Andreasberg lighthouse and the signal station on Cap Ristna. On 11–12 May, she covered another minelaying off Texel. In September 1915 she made sweeps in the Skagerrak and Kattegat. In early 1916, she covered more minelaying missions, as well as reconnaissance sweeps into the North Sea. On 23–24 April 1916, she took part in the Yarmouth-Lowestoft raid with the I Scouting Group like her sister ship.

In May 1916 that was her greatest test: The battle of Jutland. She was assigned as a leader of a torpedo boat flotilla screening the I Scouting Group’s battlecruisers, leaving the Jade roadstead at 02:00, on 31 May for the Skagerrak. Circa 15:30, she spotted and engaged the British 1st Battlecruiser Squadron but SMS Regensburg was too far in the German formation to actually fire or get fire at. She steamed to reach the fight, when engaged by battlecruisers at some 2,200 yd (2,000 m away, but she was not hit and kept her distances. At 17:10 she reached the head of the line when engaged more accurately by HMS Tiger (she was mistook by a battlescruiser in poor weather conditions).

Regensburg then led by order a general attack with her TBs, while the British counter this by their own destroyer screen, leading to a hard-fought battle at close range while capital ships startug firing with their secondary guns. At 19:00, Regensburg managed to lead her TBs for a torpeod run at HMS Canterbury and four destroyers, which disabled HMS Shark before engaging HMS Canterbury, turning covered by the mist. At 20:15, Scheer ordered a withdrawal in which the I Scouting Group would charge the British line in cover, with a massed torpedo boat attack led by Regensburg and other flotillas. It was realized later the British had turned away, out of range.

Regensburg was ordered next to organized three torpedo boat flotillas and renew night night. At 21:10, the II Flotilla and XII Half-Flotilla at the rear were pressed into attack while the rest passed behind the British fleet, reaching Horns Reef at 04:00. At 09:45, Regensburg and the three TBs on her formation met torpedo boats carrying the crew of the scuttled SMS Lützow, having spent 372 main rounds while emerged unscathed.

By 1917, she was assigned to the IV Scouting Group with SMS Stralsund and Pillau. By late October 1917, the IV Scouting Group went to the city of Pillau, arriving on the 30th to replacing heavier vessels there after Operation Albion (Gulf of Riga campaign) and battleships of the I Battle Squadron. Minefields loose after a recent storm cancelled the mission and they return to the North Sea a day after. Nothing much hapened for the remainder of the year or in 1918. A few sweeps and patrols, with nothing notable.

By October 1918 however, SMS Regensburg was flagship, Commodore Johannes von Karpf, IV Scouting Group. She was mobilized and prepared for the final large scale raid of the High Seas Fleet and on the morning of 27 October, Karpf ordered Regensburg’s crew to take on a full load of coal and oil, but many refused to obey as the the engine room personnel, still in their shore-going uniforms. They all went on stirke until First Lieutenant arrested the ringleader, jailed, after which work resumed. On the 29 October 1918, order was given to sail from Wilhelmshaven but during the night, several battleships’s crews mutinied, deserted en route and the unrest had Hipper cancelling the operation.

Regensburg was in Swinemünde on 7 November but false reports of communist-turned crewed torpedo boats had Karpf ordereding his ships to be laid up with confidential materials destroyed and ammunition magazines flooded. This proved incorrect, and the fleet command saked Karpf, replaced by Commodore Rohardt, restoring the ships in condition. The IV Scouting Group moved to Stettin, learning after the abdication of the Kaiser on 9 November. Rohardt struck down the Imperial ensign and placed Regensburg and Brummer out of commission. Lacking crew, despite a new officer, the ship was in reserved until December 1918, when she escorted the British battleship HMS Hercules carrying the Allied Armistice Commission to Kiel.


Strasbourg – credits Alex Montreal

She served a short time in the Reichsmarine, in 1919, stricken on 10 March 1920, decomm, and by 4 June 1920 sent to Cherbourg in France, in the armistic allied commission attributing vessels as war prize. She was attributed to the French as ship “J”, later renamed Strasbourg, recommissioned after many changes, including armament with the French fleet in 1922. In 1944, she was scuttled, her wreck remaining, visible at low tide.

Karlsruhe class cruisers (1912)

Karlsruhe class cruisers (1912)

German light Cruisers (1911-1914)
SMS Karlsruhe, SMS Rostock

The last German “four stackers”

With the previous Magdeburg class, the Karlsruhe were near-sister ships with the same armament, armor protection, but faster and larger. Launched in 1912 they were commissioned as the war broke out and saw plenty of action, with short but very intense career as the 30 kts vanguard ships of the Hochseeflotte. SMS Karlsruhe started with commerce raiding career, sinking sixteen merchant ships but she desappeared after an accidental internal explosion on 4 November 1914. SMS Rostock frequently screened for I Scouting Group (Battlecruisers) and saw the Battle of Dogger Bank in January 1915, several raids and the Battle of Jutland, being torpedoed by a British destroyer and scuttled.

Design Development


Bundesarchiv, SMS Karlsruhe on sea trials, 1914

The design for the Karlsruhe class was prepared in 1910, as an incremental improvement over the Magdeburg class. All authors saw them as different classes, but they shared many characteristics, being “near-twins”. This allowed to keep the good points of the design, saving time, while trying to push the envelope in some areas. Karlsruhe and Rostock had a longer hull which enable larger steam turbines and 14 boilers, increasing their output, but also a reworked hull with notably a more raked hull, although this was paid by a greater displacement. They however kept the same armament and protection.

Construction

SMS Karlsruhe was ordered in 1911 as “Ersatz Seeadler” (as a replacement for the 1890 2nd class cruiser). She was laid down in 1911 at Germaniawerft shipyard in Kiel, hull number 181. Launched on 11 November 1912, she was commissioned on 15 January 1914. Another SMS Seeadler (1888) was made famous during the war as the only master commerce raider, the “kaiser’s pirate”.

SMS Rostock was ordered as “Ersatz Geier” (another Bussard class cruiser), laid down in 1911 at Howaldtswerke dockyard (Kiel), construction number 560. Launched on 12 November 1912, just a day after her sister ship, she was completed on 5 February 1914, so had little time to train before the war broke out.

Hull construction & general characteristics

The ships were 139 meters (456 ft) long (waterline), 142.20 m (466 ft 6 in) overall, an increase of nine feets. The beam took 20 cm at 13.70 m (44 ft 11 in), the draft progressed also to 5.38 m (17 ft 8 in) forward, 6.20 m (20 ft 4 in) aft (instead of 4.40 m). Displacement rose to 4,900 metric tons (4,800 long tons), as designed (normal), and up to 6,191 t (6,093 long tons) fully loaded, to compared with the 4570/5587 tons of the Magdeburg class.

Design wise, they were close, with the same clipper bow, forecastle, low aft deck, weapons repartition, two masts and four funnels heavenly spaced amidships. They were crewed by eighteen officers and 355 enlisted men, a bit more than the previous Madeburg, but they were also larger. They carried service boats, namely one steam picket boat, a coaling barge, a cutter, two yawls, and two dinghies. Teir masts supported platforms for projectors, but in 1915, Rostock was fitted with spotting tops.

Powerplant & Performances

HD rendition, the blueprints
HD rendition, the blueprints

Both vessels had two shafts propellers (three-bladed screws 3.50 m or 11 ft 6 in in diameter), driven by two Marine-type steam turbines. Steam came from twelve coal-fired water tube boilers, plus two oil-fired double-ended water tube boilers. Total ouptut was evaluated at 26,000 shaft horsepower (19,000 kW), for a designed top speed of 27.8 knots (51.5 km/h; 32.0 mph). But as usual on trials, they exceeded these figures, Karlsruhe reaching 28.5 knots (52.8 km/h; 32.8 mph) on 37,885 shp (28,251 kW), Rostock 29.3 knots based on 43,628 shp (32,533 kW).

Autonomy wise, they carried 400 t (394 long tons; 441 short tons) of coal, 70 t (69 long tons; 77 short tons) or oil, and ASW internal voids could accept an extra 1,300 t (1,279 long tons; 1,433 short tons) plus 200 t (197 long tons; 220 short tons) or oil, respectively. Range is estimated to be above 6,000 nm at 23 kts due to their larger hull, according to Magdeburg’s data;

Electrical power came from two turbo generators, rated at 240 and 200 kilowatts respectively, both working at 220 volts.

After sea trials and some service, they were reported favoutably, their captains seeing them as good sea boats, with slight weather helm in a swell, severe leeway, slow steering and when pushed hard over, bleeding 60% speed. Their transverse metacentric height was average, at 0.79 m (2 ft 7 in). Their roll and general motion was predictable, making good artillery platforms. They were bad steamers however at the start.

Protection

The general scheme was a repeat of the the preceding class.

  • Waterline armored belt: 60 mm (2.4 in) amiships
  • WL Belt tapered down to 18 mm (0.71 in) forward.
  • Unarmored belt stern section.
  • Armored deck: 60 mm forward, 40 mm amidships, 20 mm aft.
  • Sloped armor deck: 40 mm connected to the belt.
  • Conning tower: 100 mm (3.9 in) walls, 20 mm (0.79 in) roof

For ASW protection they had their hull constructed with longitudinal steel frames incorporating some fifteen watertight compartments, plus a double bottom running for 45% of its length. Each turbine was installed in its own engine room to avoid loosing all power after a flooding. Also, their 14 boilers were split into five separate boiler rooms.

Armament


SMS Karlsruhe underway

12 × 10.5 cm (4.1 in) SK L/45 guns

Same as the Magdeburg’s: These twelve guns were placed as follows: two forward in tandem, two aft, four in sponsons and recesses to fire forward ad aft, the rest amidships. They fired at 15 RPM, firing 17.4 kg (38 lb) shells with a 25.5 kg (56 lb) fixed Brass Casing at 710 m/s (2,300 ft/s), to a max range of 12,700 m (13,900 yd) at 30°.

2 × 50 cm (19.7 in) torpedo tubes

Standard G7 type (1913) also used by the Magdeburg: Submerged on the broadsides. They carried a 430 lbs. (195 kg) Hexanite warhead, reaching 4,370 yards (4,000 m) at 37 knots or 10,170 yards (9,300 m) at 27 knots depending on the setting. They were powered by a Decahydronaphthalene (Decalin) Wet-Heater.

120 × mines

Likely the R-Mine standard type using a 330 lbs. (150 kg) wet gun cotton charge. They were carried on deck rails on either side, starting after the forecastle.

SMS Karlsruhe


SMS Karlsruhe coaling at San Juan P.R.

SMS Karlsruhe (contract name “Ersatz Seeadler”, laid down at Germaniawerft, Kiel, 21 September 1911 and launched, chistened by her namesake mayor, Karl Siegrist, on 11 November 1912. Fitting-out was followed by the yard’s trials in mid-December 1913, and official sea trials revealing excessive coal consumption.

Commissioned on 15 January 1914, she spent the months before the war training under command of her first captain, Fregattenkapitän Fritz Lüdecke. Fixes needed extra trials which went on until June. However even after yards’s modification, this was not much improved and she was scheduled for the East American Station, to relieve SMS Bremen, but she was replaced by Dresden and only departed Kiel on 14 June.

On 1st July, she was in Saint Thomas, dropping anchor in the Danish West Indies. As new from the Balkans saw rising tensuions, she was sent to watch over German Nationals in Port-au-Prince, Haiti during civil unrest, until 9 July. She was ordered newt to meet SMS Dresden in Veracruz (Mexico) but the situation degraded further in Haiti and she stayed, only ordered to leave by 27 July. Both cruisers exchanged commanders, with FK Erich Köhler now taking command of SMS Karlsruhe while Lüdecke was ordered to conduct Dresden back to Germany.

SMS Karlsruhe was to take part in the opening ceremonies of the Panama Canal, but Köhler decided decided to avoid the numerous British and French warships present here and instead headed for Havana, Cuba, and on 30 July, left and stayed close to shore before, heading for a Cay Sal Bank (Straits of Florida) and then evaded any pursuers by broadcasting a message in the open as she was to head for Tampico (Mexico) on 4 August, where the present armored cruiser HMS Berwick awaited here. Köhler armed the passenger ship SS Kronprinz Wilhelm as an auxiliary cruiser and next steamed east into the Atlantic, receiving news of the war underway in the 3/4 August night.

Her standing orders were to conduct commerce raiding, targeting British merchant traffic. Karlsruhe, Dresden and auxiliary cruisers mobilized from the Royal Navy no less than five cruiser squadrons, including one headed by Rear Admiral Christopher Craddock, and Rear Admiral Archibald Stoddart. Ships were dispersed, covering the vast sways of the Atlantic. Based on maps, the commanders planned possible routes two and from the coaling stations where they might intercept them.

On 6 August, SMS Karlsruhe met Kronprinz Wilhelm 120 nmi north of Watling Island (now San Salvador). She was transferring guns and equipment to SS Kronprinz Wilhelm when Craddock (HMS Suffolk) was spotted approaching from the south. Only two 8.8 cm guns and a machine gun were transferred before the two ships parted over quickly. Suffolk followed SMS Karlsruhe and the hunt was launched, communicated to other cruisers. However, being faster, she evaded Craddock.


Operations of SMS Karlsruhe: The general map


Operations of SMS Karlsruhe in October 1914

At 20:15 however, HMS Bristol spotted underway the cruiser and opened fire. Karlsruhe gunners replicated and scored two hits on Bristol, forcing her to slow down. Karlsruhe turned east and evaded her. By 9 August, SMS Karlsruhe reached Puerto Rico. It was time: She only had 12 tons of coal left, and resupplied from a HAPAG freighter before departing for Brazil, hoping to prey on large merchant traffic and not well patrolled.

She alsto stopped in Willemstad, Curaçao to take more coal and oil and reached the northern coast of Brazil, spotting and sinking a first British steamship (18 August). Until 23 August, she roamed off Maraca island, on the mouth of the Amazon river, replenishing coal again from a German steamship. One of those planned in advance as colliers to support such operations in neutral waters, at pre-planned meeting points. Captain Köhler also preferred to capture vessels and take all the coal he could onboard.

He kept prizes also for target training. Patrolled the eastern coast of South America down to La Plata (Argentina) she sank/captured sixteen merchant ships, of which 15 British, 1 Dutch for 72,805 GRT. Next SMS Karlsruhe headed to the West Indies, to prey on Barbados, Fort-de-France, and Trinidad.

Underway on 4 November she had a spontaneous internal explosion however, at 18:30. The hull broke in two, the bow section sinking rapidly with a large portion of the crew, including Köhler and his staff. The stern remained afloat saving the lived of the 146 that escape onto the attending colliers: The SS Rio Negro and SS Indrani. At 18:57 the stern sank in turn, and Commander Studt became the senior surviving officer. The crew was trasferred to the SS Rio Negro while he scuttled SS Indrani and proceeded to Iceland, going through the British blockade of the North Sea in a storm, dropping anchor at Ålesund, Norway. Germany kept the loss of the ship a secret to keep the British occupied until they learned about it on March 1915. This smart move had tied down eleven British cruisers for almost six months after her loss.

SMS Rostock


SMS Rostock was ordered as “Ersatz Geier”, laid down at Howaldtswerke, Kiel in 1911, launched on 12 November 1912 (christened by the mayor of Rostock, Dr. Magnus Maßmann) and commissioned on 5 February 1914, assigned as a torpedo boat flotilla leader. She trained until the war broke out, not showing the same coal cinsumtin exceses of her sister ship. Her career was also less adventurous.

On 24 January 1915, SMS Rostock was part of the screen force dedicated to Admiral Franz von Hipper’s I Scouting Group Battlecruisers. She took part in a first sortie near the Dogger Bank with three other light cruisers and 19 torpedo boats. Rostock stayed with a TB flotilla to screen the port flank of the battlecruiser squadron until five British battlecruisers were spotted, leading to the Battle of Dogger Bank. Rostock later took part in in the raid on Yarmouth and Lowestoft (24 April 1916), engaging the Harwich Force and other sorties in between all along 1915.

The Battle of Jutland was her final test: On 31 May 1916 she was still leader of two torpedo boat flotillas, flagship of Kommodore Andreas Michelsen. They were to screen for the battle squadrons and at 17:30, the British destroyers HMS Nestor and Nicator attempted an attack, while Rostock engaged them, quickly disabling both with assistance of the Battleships.

At 19:32, SMS Rostock and her torpedo boats layed a smoke screen to cover the general withdrawal. Michelsen later detached several torpedo boats to assist the badly damaged SMS Lützow. The fleet took its night cruising formation while Rostock escorted the light cruisers of IV Scouting Group, port of the formation. They sumbled upon the 2nd Light Cruiser Squadron after midnight, and later the British 4th Destroyer Flotilla. Rostock followed the cannonade and went right into the path of incoming destroyers, which immediately launched several torpedoes. Rostock and the other cruisers turned away, which sent them right uinto the bows of the battleships in I Battle Squadron. Rostock avoided collision but Elbing was rammed.

Rostock’s search lights at some point uncovered the destroyer leader HMS Broke. Gunfire from the German cruiser sters, soon joined by Westfalen and Rheinland. Broke was heavily damaged but managed to reach port. Next Rostock ws attacked by HMS Ambuscade and Contest, firing a single torpedo each, at max speed settings and just 1,000 yd (910 m). This was a right decision, which cost a single hit on Rostock at 1:30, followed by firce gunfire, where she was hit by three 4 in shells, which disabled her. The destroyer S54 joined to assist, taking her in tow at 10 kn (19 km/h; 12 mph), soon joined by V71 and V73 detached from the flotilla.

But luck ran out: At around 03:55, 1 June 1916, British cruiser HMS Dublin spotted the slow-moving formation, easy prey. The three destroyers evacuated her crew before flashing the first two letters of the British signal challenge to gain time, then laid down Smoke screens, leaving some extra ten minutes for S54 to depart with Rostock’s crew aboard. V71 and V73 stayed behind to scuttle the crippled cruiser with charges set completed by three torpedoes fired. The cruiser sank bow-first at around 04:25, with 14 men killed, 6 wounded during the battle. The cruiser had spent some 500 rounds for her main guns, the most of any other German cruiser present, but had little to show for it.

Bayern class: The last German dreadnoughts

The battleship “Bayern” does not represents the culmination of the German Dreadnought, but at least its wartime epitaph. The very last projected German dreadnoughts were indeed the “L20 alpha” class, reaching almost 50,000 fully loaded, 26 knots, and with eight 16.5 in (42 cm) guns. The battlecruisers of the Mackensen class were the most advanced in construction, more than the Sachsen class, a modified Bayern design. There are integrated in this study for practicity as very close, near sister-ships.

Th Bayern were at least quite a major leap forward in design, eclipsing all previous classes of German dreadnoughts. Indeed, the previous class, the Königs, completed as late as in 1915, were still armed with 12-in guns (30.5 cm), as all their precedessors but the Nassau. This was a considerable issue explained by many factors, which clearly made on paper German battleships inferior in range and hitting power to their British counterparts. The Royal Navy had in its divisions the 13.5-in (343 mm) armed Orion, King Georges V and Iron Dukes. They made indeed the bulk of the RN (12 in all) when the König class was just getting started. German intel also new of a new class in construction since October 1912, one year after the start of the Königs, and they were all armed with 15-in guns (381 mm). This of course caused a lot of concerns with the German admiralty, understandably as their hitting power was almost double than 12-in shells. One response was improving the armour again, but admiral Tirpitz at the time was very aware that an appropriate answer was needed asap in gunnery also. That’s what made the Bayern so special: They leapfrogged directly from the 12-in to the 15-in caliber !

Gunnery errand

In 1911, when the König class was started, all armed with the 30.5 cm/50 (12″) SK L/50 which was quite an improvement over the Nassau’s 28 xm, the admiralty was aware that no gun beyond 12-in was available in the works, but a 12.7 in (323 mm) which was basically a relined and reinforced 12-in as a stopgap measure. In fact, the fourth König authorized under the 1912 program was considered by naval command to be quipped with this 32.3 cm (12.7 in). The increase in weight would be offset by reducing the secondary battery with 12 cm (4.7 in) guns instead of 6-in. There was also a possible alternative, the 35 cm/45 (13.78″) SK L/45 planned for the Mackensen class battlecruisers. Design started in 1914, but as the class was never completed, the thirteen produced ended on railways carriage for the western front. The 12.7-in caliber planned for the fourth König however never passed the drawing board stage. None was built.

The proposal was ultimately rejected for a sister-ship of 1911 vessels, in order to create a homogeneous four-ship division, mirroring the British ones. This allowed to simplify tactical command. The Kronprinz’s diesel was dropped, never ready in time, for classic turbines, but was the first fitted was a larger tubular foremast to support a heavier, more capable fire direction top, later later retrofitted to the other members of the class and the Hindenburg, as well as the Bayern class. Meanwhile, work has started in 1913 on a much better proposition, a 38 cm/45 (14.96″) SK L/45. This was retained for the genesis of the next dreadnoughts, specifically to counter the QE class.

Design development of the Bayern class

Design work for this new class began in fact way earlier than the British QE class was known about, as early as 1910. At the time indeed, the admiralty already envisioned for the König class an upgrade in artillery, as it had become clear that other navies moved away from the 12 in and larger guns were to be envisioned for the German Navy in the near future. In November 1909 indeed, the British laid down the HMS Orion, first of their “super dreadnoughts”, armed with 13.5 inches guns.

If the Weapons Department suggested a 32 cm (13 in) gun to answer it, during a meeting on 11 May 1910, Admiral Alfred von Tirpitz State Secretary of the Reichsmarineamt announced that budgetary constraints at that time precluded the adoption of anything else than the existing 12-in. The 1912 Agadir Crisis had Tirpitz surfing on the resulting public outcry over British involvement in it to have the Reichstag quicky appropriating funds for the Kaiserliches Marine. Tirpitz obtained that a 34 cm (13.4 in) gun design would be started in mid-1911.

In August 1911, the design staff was also asked to start studies of larger ordnance, a 35 cm (13.8 in), a 38 cm (15 in), and even a 40 cm (15.7 in) artillery piece, that would have given quite an advantage over the Royal Navy at the time. The 40 cm was defined as a possible maximum caliber as it was assumed that British wire-wound guns could not be larger. A meeting in September secured preferred designs, and one with ten 35 cm guns in five turrets was put on the table and dicusses, as well as a 40 cm guns, four turrets.

The Weapons Department wanted to puh forward the 35 cm gun design, stating that it had a 25% greater chance of hitting its target. Tirpitz on the other hand wanted to try a mixed battery of twin and triple turrets. After examining the gun turrets of the Austro-Hungarian dreadnoughts of the Tegetthoff class, it was determined that triple gun turrets were problematic still so this option was dropped. Their increased weight as well as reduced ammunition supply, rate of fire, loss accuracy, abrupt loss of fighting capability if one was disabled, were all cited as arguments.

Still working on the 35 cm ship design, displacement was estimated around 29,000 t. Its cost was about 59.7 million marks. The 40 cm proposal was rated just as 60 million marks, but displaced even less, at 28,250 t, yet Tirpitz estimated they were both too expensive. The Construction Department then proposed a 28,100 t, eight 38 cm gun design, curtailing the overall cost to 57.5 million marks. This was adopted 26 September 1911 for the next design, but this meant studies made for previous guns might be redirected in this new compromise 38 cm caliber formally adopted on 6 January 1912.

The same year, design work progressed, while improvements in the armor layout were also studied to create a real difference with the König class. In addition, they were to be armed with eight 8.8 cm (3.5 in) anti-aircraft guns, a bold more given the state of aviation in 1912. Neverteless, this was reduced when completed to just two. Powerplant-wise, the admiralstaff still wanted to try the idea of diesel engines, but previous experiences showed, this time again, it was wiser to fit steam turbines again, hoping that over time a thord of fourth ship could adopt such powerplant, which would have given a much greater range. No reliable diesel engines existed either in 1913 ot even 1914 for that scale. They stuck to less demanding U-boats instead. Note that this German obsession for diesel power for battleships was never realized for any navy, but the concept was sound enough to see the light of day for smaller ships in the cold war, notably frigates and even destroyers thans to combined powerplants. Meanwhile in the USA, engineers wanted to go full electric.

Funding for the new battleships was allocated at last under the fourth Naval Law in 1912. This however only secured three new capital ships, two light cruisers, and salaries for 15,000 officers and men. Eventually the capital ships laid down that year were the Derfflinger-class battlecruisers. Bayern and Baden were funded only in 1913. Sachsen in 1914, Württemberg at last, in the War Estimates. As usual they went in pair with justified replacement for older pre-dreadnoughts, which in that case were the last Brandenburg-class pre-dreadnought SMS Wörth and the SMS Kaiser Friedrich III, Kaiser Wilhelm II and Kaiser Friedrich III.

In 1920-21, a British team make a thorough description of the largely intact SMS Baden, before testing her through and through, making her the best known German battleship. The result of these reports was condensed and published in “Engineering”, March 18, 1921 in several plates up to page 335.


Reconstitution of Baden’s design from the 1920-21 studies.

Bayern and Baden, with their very modern design perfectly embodied the future evolution of this type. Responding to British Queen Elizabeth, they have equivalent artillery caliber while being shorter by 49 feets (15 meters) but wider by 9.5 fts (three meters), they had the same displacement, slightly lower speed, but arguably a much better armour design, which was the point in German thinking. The QE on their side were almost designed as intermediary between dreadnoughts and battlecruisers, with speed in mind -Fisher obliges- their firepower somewhat compensating in that area. The Bayern’s fire control system was similar to that of the Hindenburg but however much more advanced than the QE equivalent, attracting after the war great interest from the Royal Navy authorities in Scapa, where both were scuttled.

Hull and general design

SMS Bayern and Baden both had the same lenght at the waterline of 179.4 m (588 ft 7 in), but 180 m (590 ft 7 in) overall. The next Sachsen and Württemberg were two meters longer, but all four had the same beam, of just 30 m (98 ft 5 in). Draft for the first two was 9.3-9.4 m (30 ft 6 in-30 ft 10 in). Standard displacement as designed was calculated at 28,530 t (28,080 long tons) and fully loaded 32,200 t (31,700 long tons). The Sachsen pair were were slightly heavier. All four however has the same hull construction using transverse and longitudinal steel frames, with an outer hull made of reiveted plates. The underwater protection comprised 17 watertight compartments, a double bottom on 88% of the total length of the hull.

Crew as designed comprised 42 officers, 1,129 enlisted men but Baden, fitted as squadron flagship, carried in addition 14 officers and 86 sailors. Their small boat fleets, mostly located under the funnels amidships, comprised notably a single picket boat, three barges, two launches, two yawls, and two dinghies.

Armor protection


Armor scheme view

The Bayern-class had arguably the best “classic” protective scheme so far of any German battleship, although it was still “pre-jutland”. Krupp cemented steel armor all round, with an armor belt 350 mm (14 in) thick for the central citadel. It was covering also the ammunition magazines and the machinery spaces.

-The belt then tapered down to 200 mm (7.9 in) forward and 170 mm (6.7 in) aft of the barbettes, leaving the last sections ends unprotected. There was a 50 mm (2 in) torpedo bulkhead over the entire lenght behind the main belt.

The main armored deck was just 60 mm (2.4 in) thick, but up to 100 mm (3.9 in) over the magazines, machinery and steering room. Again, this was “pre-jutland”.

-The forward conning tower (CT), had 400 mm (16 in) thick walls. The roof was 170 mm in thickness. The aft CT was much lighter, with 170 mm thick walls, 80 mm (3.1 in) thick armor plated roof.

-The main battery gun turrets had 350 mm thick faces and sides, 200 mm thick roofs.

-The 15 cm guns casemates were protected by 170 mm thick armor plated walls while behind there was enxtra shield, 80 mm thick to protect the crews from shell splinters.

Powerplant

Baden closeup

SMS Bayern and Baden were planned with the standard, and properly German configuration of three shafts: The central one could be used to test different configurations (like a VTE) for economic cruise, and better range. However, since Germany took some advance in the design of diesels, it was hope to install one instead of a VTE. But the planned diesel, properly enormous and able to deliver the record power of 12,000 bhp, was still not ready in 1914, nor in 1915. It was postponed for the next Sachen but in the end, never ready before the war ended. Eventually, it was found wiser to give both ships the same three sets of Parsons turbines, driving three-bladed screws, 3.87 m (12.7 ft) in diameter.

Steam came from eleven coal-fired Schulz-Thornycroft boilers, plus three oil-fired Schulz-Thornycroft boilers, so mixed-heating, planed in nine separated boiler rooms. This powerplant was calculated to deliver and estimated output of 34,521 shaft horsepower (25,742 kW), at 265 revolutions per minute. On trials in 1916-17, both vessels in fact achieved the much greater output of 55,201 shp (41,163 kW) and 55,505 shp (41,390 kW) respectively, for a top speed of 22 knots (41 km/h; 25 mph).

They were designed to carry in peacetime 900 t (890 long tons) of coal, 200 t (200 long tons) of oil. In wartime, by filling all safety void spaces in the hull, this went largely up, at 3,400 t (3,300 long tons) of coal, 620 t (610 long tons) of oil, so basically more than triple. This enabled 5,000 nautical miles (9,300 km; 5,800 mi) at 12 knots, reduced at 4,485 nmi on the more sustained 15 knots and 3,740 nmi, 2,390 nmi at 17 and 21 knots respectively. Electrical output was alrso greater than previous ships, with no less than eight diesel generators to provide a total of 2,400 kilowatts combined, at 220 volts.

On trials, both vessels showed to be exceptional sea boats in all reports. They were were both very stable and very maneuverable, which was difficult to achieve together. They of course lost bled speed in heavy seas, but just slightly, and lost up to 62% speed with the rudders hard over, heeling over 7 degrees which was not bad overall. Their metacentric height was rather excellent at 2.53 m (8 ft 4 in), in fact larger than British Queen Elisabeth and Revenge, making them excellent, very stable gun platforms with a gentle, predictive motion, perfect for the conditions of the Baltic. All these were conformed later by the British long study of the Baden, just by calculating her hull shape and proportions.

Armament

Main: 4×2 38 cm SK L/45


Main armament, top view scheme

The Bayern class main battery comprised eight 38 cm (15 in) SK L/45 guns. They were paired in four Drh LC/1913 turrets, a new pattern which allowed a depression/elevation of −8 + 16°. Reload however could only be done at 2.5°, which of course slowed down the rate of fire, of around one shell every 38 seconds, or less than 2 rpm. Gun mountings for Bayern were later modified, the barrels going up to 20° at a cost of a lower depression at −5°.

Maximum range initially at 16° was 20,250 m (66,440 ft). Later, Bayern’s modified cradle authorizing 20° translated into 23,200 m (76,100 ft). All turrets were also fitted with their own stereo rangefinder. In total, 720 shells (90 per gun) were carried. They were in standard 750-kilogram (1,650 lb) AP shells, relatively light for this caliber, lighter than the British 16-in shells. They also carried less high explosive shells, in general only 1/3 of the total. At 20,000 m (66,000 ft), their AP shells was calculated (and tested) able to defeat up to 336 mm (13.2 in) of steel plate. Muzzle velocity was 805 meters per second (2,640 ft/s).

Post-war tests of these guns, conducted by British Royal Navy engineers in 1919-21 showed their readiness to fire after a 23 seconds process after firing, faster than British Queen Elizabeth class (36 seconds between salvos). Paradoxally, they found also German anti-flash precautions to be inferior of those practiced after Jutland. German brass propellant cases however proved safer, less susceptible to flash detonations.

Secondary: 16×15 cm (5.9 in) SK L/45

The Bayern (and Sachsen) classes secondary battery comprised sixteen 15 cm (5.9 in) SK L/45 quick-firing guns, all in armored casemates along the the side of the top deck, relatively high to avoid water spray.

This was two more than for the König class. They were intended to deal against destroyers and torpedo boats. In total they carried for these a total of 2,240 shells, presumably all HE. These 45.3 kg (99.8 lb) shells used a separated 13.7 kg (31.2 lb) RPC/12 propellant charge, in a brass cartridge, avoiding flash detonations. Muzzle velocity was 835 meters per second (2,740 ft/s), rate of fire 5-7 rpm, practical mage range 13,500 m (44,300 ft) and after changes of cradles in 1916-17 at 16,800 m (55,100 ft). Barrel life was approximatively 1,400 shots.

Tertiary: 2×8,8 cm (3.5 in) SK L/45

The Bayern class were originally design to also have just two light guns for dual/AA purpose. In 1914, aviation was not the threat it became in 1917. Therefore, from the two 8.8 cm (3.5 in) SK L/45 flak guns, masked and supplied with 800 rounds, six more were installed during the war on the battery deck, so eight total.

-MPL C/13 mountings (−10 +70° elevation)

-9 kg (19.8 lb) HE shell

-Ceiling 9,150 m (30,020 ft)/70°

Torpedoes: 2×60 cm (24 in) TTs

Unlike the previous König class, which had six 50 cm torpedo tubes, the Bayerns swapped onto a new caliber, 60 cm (24 in), on five submerged torpedo tubes: One in the bow, two on each broadside, none in the stern. Also, some 20 torpedoes were carried for reloads. “H” designated the 60 cm caliber and “G” the more standard 53 cm, “F” for airborne torpedoes. Technically “J” (70) and “M” (75 cm) also existed. Only J9 was planned in 1912-1915 but never entered service, able to reach 18 km (19,700 yds).

No doubt it inspired the Japanese to create their “long lance”, at least in concept ater the war. The H8 was also used on the Mackensen, Lützow, Hindenburg, Cöln II and Dresden II class, and the destroyer S 113. Design started in 1912, and the H8 model entered in service in 1915, powered by a Brotherhood system wet-heater.

H8 type torpedoes: 8 m (315 ft) long, 210 kg (463 lb) Hexanite warhead.

Range 8,000 m (8,700 yd) at 35 knots, or 6000 at 36 kts, 15,000 m at 28 knots or 14,000 (15.310 yds) at 30 kts.

However after Jutland, where these capital ships torpedoes proved useless, Bayern and Baden struck mines in 1917 and this trigerred a structural overhaul which first consequence was to get rid of the torpedo tubes, rooms, removed and plated over, for extra protection instead.

Construction of the Bayern class (1913-1917)

-Bayern (“Bavaria”) was regarded as a simple addition to the fleet, ordered under the provisional name “T”. She was laid down as construction number 59 in Howaldtswerke, Kiel on 22 December 1913, launched on 18 February 1915 and completed on 15 July 1916.

-Baden (another ancient kingdom) was ordered as Ersatz Wörth (a replacement for the latter), as construction number 913 at Schichau-Werke in Danzig, on 20 December 1913. She was launched 30 October 1915 and only commissioned on 14 March 1917.

-Sachsen was ordered as Ersatz Kaiser Friedrich III in Germaniawerft, Kiel as construction number 210 on 15 April 1914, launched on 21 November 1916 but never completed.

-Württemberg (Saxony province) was ordered as Ersatz Kaiser Wilhelm II at AG Vulcan, Hamburg as construction number 19 on 4 January 1915, launched at last on 20 June 1917, but also never completed.

Now let’s study the war consequences on their construction time: It took fifteen month to launch for SMS Bayern, and 17 months to completion, for Baden 21 months to launch and 18 months to completion, and for Sachsen and Württemberg, 32 and 30 respectively or more than two years and several months for each. They were, also respectively however only nine and twelve month from completion.

To put it simply both were suspended when the war broke up, and work resumed afterwards, with a reduced workforce and materials. A classic scheme for every major warship construction project in wartime.

The Sachsen class (1916)

The incomplete Sachsen
The incomplete Sachsen, still with all her decks complete and funnels in place, CT, barbettes, main turrets, casemates and part of the superstructure but no barrels, in 1918.

It’s the appearance of the Queen Elisabeth class which prompted extensive modifications on the Sachsen, resulting in a sister class, classed as independent in most publications due to the amount of specificities.

The German Navy started to begin construction for FY 1914 battleship “Ersatz Kaiser Friedrich III”, voted 1912 as replacement for the pre-dreadnought Kaiser Friedrich III. But the design staff at that stage were aware of the new Queen Elizabeth class high top speed. There was yet another attempt to fit a diesel engine, at least on her center propeller shaft, both as a reduced size power addition and main propulsion for economical cruise. This was envisioned earlier for the König but the diesels were never ready in time. It nevertheless added 200 t more in the displacement, required the engineers to lengthen the hull by 2.4 m (7 ft 10 in), in order to keep the draft intact (and therefore the verstical position of the armour belt). This allowed to refine the hull lines, improve hydrodynamics, which added to the new engine, increasing top speed as expected. Some historians like Dirk Nottellmann considered these changes alone were sufficient to make Sachsen and Württemberg, a sub-class.

Hull & general characteristics

SMS Sachsen and Wurttemberg had aboy the same increased dimensions: 181.8 m (596 ft 5 in) long at the waterline, 182.4 m (598 ft 5 in) overall for a beam of just 30 m (98 ft 5 in) and draft between 9.3 and 9.4 m (30 ft 6 in–30 ft 10 in aft). Calculated displacement was to be 28,800 metric tons standard as designed and unloaded. The fully loaded displacement was evaluated to be over 32,500 metric tons. The crew was comparable to the previous vessels, but greater, with 42 officers and 1,129 enlisted men. The profile was very similar by the Conway’s profile shows exactly the same appareance with perhaps taller funnels for a better air draft and an aft mainmast from the start, also supporting projectors platforms.

Powerplant

Sachsen and Württemberg were intended to be one knot faster than the earlier vessels, thanks to a slightly more powerful machinery (Württemberg) and finer hull lines. SMS Württemberg had the usual three shafts, with AEO-Vulcan geared steam turbines 47,343 shp (35,304 kW), for the calculated speed of 22 knots. Sachsen also had three shafts, but with a planned MAN diesel rated at 11,836 bhp (8,826 kW) on the center shaft, and Parsons steam turbines on the outer shafts. This choice caused concerns: The diesel engine was not ready still in 1918, but in 1919, captured and seized by the Naval Inter-Allied Control Commission. Also the Parsons were likely to be ordered to UK, unless licenced-built in Germany, also causing an abrupt end in 1914. All in all, this mixed powerplant was rated at 53,261 shp (39,717 kW) for 22.5 knots. Cruising range would have been calculated about 5,000 nautical miles (9,300 km; 5,800 mi) at 12 knots.

Revised armament

Both were planned to be armed with the same eight 38 cm (15 in) SK L/45 guns, also arranged in four twin-gun turrets fore and aft in deck and superfiring pairs. The secondary armament comprised also sixteen 15 cm (5.9 in) guns, but four 8.8 cm (3.5 in) guns instead of just two. They also were supposed to carry five 60 cm (23.6 in) torpedo tubes, all submerged and fixed in the bow and broadsides in pairs. Also, the guns that had been constructed for them, and never installed, were eventually recycled as heavy siege guns used on the Western Front and during WW2, coastal guns on the Atlantic wall, and railway guns on various fronts, called “Langer Max”.

Revised Protection

SMS Sachsen’s armor layout was modified as per the installation of the taller planned diesel engine. This meant that a glacis was added over the diesel, 200 mm thick (7.87 in) for its sides, 140 mm (5.5 in) on noth ends, 80 mm thick for the top plates (3.14 in). Sachsen’s belt was modified, as she was exteded to 30 mm (1.2 in) past the forward 200 mm thick section, rather than northing at all like on the Bayerns.

Württemberg on the other hand a 170–350 mm (6.7–13.8 in) armoured belt, 60–100 mm (2.4–3.9 in) thick armored deck, same 400 mm (15.7 in) forward conning tower, same plating for the main battery turrets (350 mm thick sides, 200 mm roofs) as other details of the casemates.

Bayern

The Bayern and Baden in action

Bayern and Baden were launched in 1915 but only entered served in July 1916 and March 1917, too late to participate in major naval operations, and moreover the important Battle of Jutland. Their career was rather uneventful. SMS Baden hit on a mine in the Gulf of Riga and was never repaired full until 1921, she only left to serve as a target. Bayern was interned in Scapa Flow and scuttled like the rest of the fleet in June 21, 1919.

A long pre-commission workout

SMS Bayern emerged from Howaldtswerke, Kiel after fitting-out to be commissioned on 18 March 1916, so weeks before the Battle of Jutland. Her total cost has been 49 million Goldmarks, among the highest of any German ship ever. However she remained largely idle in port in April, with a limited crew and undergoing initial tests. These also included inclination tests, to see her response to controlled flooding. Her first trip at sea was on 15 April, for her proper trials and her first live fire tests for her brand new main battery. SMS Bayern made her full-power speed test on 25 April off Alsen island, until 2 May. Back home for fixes, she was at last declared ready for service on 15 July. By that time context had changed dramatically for the Hochseeflotte.

She joined the III Battle Squadron but was not pressed into exercizes as her new crew, coming from the decommissioned SMS Lothringen was given leave at that time. Her first commander was Kapitän zur See Max Hahn, and Ernst Lindemann (yes, that one, onboard Bismarck in May 1941) was back then a wireless operator on board. On 25 May 1916, while still in trials and training, she was visited by Ludwig III of Bavaria, last King of Bavaria. She became fleet flagship on 7-16 August.

August and October 1916 sorties

The Hochseeflotte was not completely inactive from Jutland up to the end of the war though: Admiral Reinhard Scheer wanted a fleet sortie in force on 18–19 August 1916, with the usual bait: A bombardment by I Scouting Group (battlecruisers), to draw out and destroy Beatty’s own battlecruisers on a pre-positioned Hochseeflotte battle group. But by that time, SMS Moltke and Von der Tann were the only ones not in repairs or completion (like Hindenburg), so he decided to assign three modern dreadnoughts to their unit: SMS Bayern and the König-class SMS Markgraf and Grosser Kurfürst.

Scheer would then follow behind with the High Seas Fleet (15 dreadnoughts) in cover. This Ist Scouting Group had different speeds and needed familiarization exercises, starting on 15 August. Hipper reported the slow speed of the battleships to Scheer as an hinderance, while Hipper insisted them not to exceed a distance of 20 nautical miles (37 km; 23 mi) from the main fleet to avoid being cut off. Basically this was just beyond the maximal sighting abilities of British lookouts in pristine weather.

The fleet sorties on 18 August as planned, but the British were soon aware of it thanks to communications decoded by Room 40 and the Grand Fleet departed to meet them. At 14:35, on 19 August, Admiral Scheer had been warned of the the British by a picket ship, and turned his forces waya, retreating. It was found too risky so close to the battle of Jutland. But this was wildly criticized. There was another sortie into the North Sea on 18–20 October, but this time they met no British naval forces and just went back home. The High Seas Fleet was reorganized on 6 December 1916: SMS Bayern was made second, III Squadron, not outfitted as a squadron flagship.

Operation Albion

pic

In early September 1917, as German troops managed to capture Riga, the German navy was assigned the task of completely evicting Russian naval forces in the Gulf of Riga to complete operations in thi sector. The Admiralstab wanted to seize Ösel Island and neutralize the Sworbe peninsula Russian batteries. On 18 September, a joint Army-Navy operation was planned, which also included Moon island, led by flagship SMS Moltke and the III Battle Squadron: Vth Division (Bayern, four König-class battleships), VIth Division (Kaiser-class battleships), accompanied by nine light cruisers, 3 torpedo boat flotillas, and a score of minesweepers to screen their way. This operation featired the largest fleet ever assembled in the Baltic so far, 300 ships, supported by over 100 aircraft, 6 zeppelins. In the gulf, the only force availanle on the Russian size was the old Russian pre-dreadnoughts Slava and Tsesarevich, and the armored cruisers Bayan, her sister ship Admiral Makarov, and Diana plus 26 destroyers, plus torpedo boats and gunboats. The garrison of Ösel however was a force 14,000 strong, with bunkers, trenchs, barb wire and fortified guns positions, plus numerous machine-guns nests.

The operation started on 12 October. Bayern, second in line behind Moltke, followed by the four Königs, placed on a broadside position, out of range of the suppose d lighe Russian guns to fire her main battery on Tagga Bay. The five Kaisers engaged on their side, the Sworbe peninsula’s batteries. Both positions indeed defended the narrows between Moon and Dagö islands: This was the only escape for the Russian fleet in the gulf and only option to mopup the Russian anaval forces in this operation.

Bayern however soon struck a naval mine at 5:07 as she shifted position to Pamerort. The blast close to the bow killed a officer and six sailors. She was also flooded by 1,000 metric tons of seawater and plunged forward to 2 m (6.6 ft), but was still able to engage Cape Toffri’s battery (south of Hiiumaa). She departed at 14:00 to be examined on 13 October, in Tagga Bay. Temporary repairs were not sufficient and she was sent back to Kiel for full repairs, that she joined in 19 days. This had her inoperative until 27 December 1917. Engineers took the occasion to get rid of her forward torpedo tube room, freeing the compartment and sealing the port turned into an additional watertight compartment. She also saw the addition of four 8.8 cm SK L/30 AA guns, making now a total of six. Meanwhile, operations saw the indecisive battle of the Gulf of Riga, with Slava and Bayan engaged and forced to withdrawn. The Operation was a success.

Last Operations (1918)

SMS Bayern was assigned to “security duties” in the North Sea, with a few sorties not far fro the shores, and far in between. Meanwhile, Scheer changed tactics, mobilizing his light surface forces to attack British convoys bound to Norway from early 1917. Ths trigerred the RN to commit battleships to the escort. This division allowed Scheer to destroy this detached squadron. Now feeling his communications had been intercepted in the past, her ordered strict wireless silence. Hipper’s battlecruisers were sent to attack the convoy on 23 April, while the High Seas Fleet was placed in distant cover as usual.

On 22 April, Bayern with the fleet assembled at Schillig Roads (Wilhelmshaven) departing at 06:00 and mking their way in heavy fog which delayed them, remaining inside their defensive minefields. Hipper’s couting force arrived 60 nmi (110 km; 69 mi) west of Egerö (Norway) on 24 April, the expected convoy route but due to faulty intelligence from U-boats he completely missed the convoy and had to fold down. In addition Moltke lost a propeller, further weakining his force, and forcing to break radio silence, which of course prompted the Royal Navy into action, Beatty soon at sea with 31 battleships, four battlecruisers. Moltke was later torpedoed by E42 underway. This was basically the last active sortie of Bayern.

Fate of Bayern

SMS Bayern Illustration at Scapa Flow

SMS Bayern Illustration in Scapa Flow

from 23 September to early October, SMS Bayern became flagship of III Squadron (Vizeadmiral Hugo Kraft). She was mobilize in Octoer for the famous “death ride”, last planned sortie in force of the High Seas Fleet as the end was near, to openly engage the British Grand Fleet in a last stand for honour. Scheer, Großadmiral wanted to inflict maximal damage in order to gain a more favorable bargaining position to Germany in the future peace negociations, but this plan backfired: Disgruntled and war-weary sailors, influenced by revolutionary spitit in Berlin, started to desert, riot and mutiny in numerous ship.

On 24 October 1918 as order was given to join Wilhelmshaven, on 29 October ships of III Squadron saw crew refusing to weigh anchor, sabotages on Thüringen and Helgoland. On Bayern however the crew seemed mostly loayal, but the whole operation was cancelled and the III Squadron, was sent back to Kiel, to await her fate. After the capitulation of November 1918, the bulk of the High Seas Fleet sailed out to be interned in Scapa Flow, under a massive allied escort. SMS Bayern was listed among these, departing on 21 November 1918.

She would remain in captivity during negotiations. On 21 June, Von reuter, having sent back already large portions of his most troublesome sailors, saw the deadline to sign the treaty and a providential British fleet sortie for training maneuvers as an opportunity to order a general scuttling. Bayern sank at 14:30 that day. She gently settled on the bottom, but with a considerable list, mostly emerging. She would be only raised on 1 September 1934, BU in 1935 in Rosyth. Her bell is now in Bundesmarine’s Kiel Fördeklub.

SMS Baden


Prow SMS Baden underway 1917

SMS Baden was not completed at Schichau-Werke dockyard, Danzig soon after 30 October 1915. Indeed, the war crippled the workforce and starved the yard from resources, redirected elsewhere. Delays amounted as in addition, the surprisingly fast initial Russian advance into East Prussia threatened directly the shipyards. It was only with the Battle of Tannenberg that it was stopped. Work resumed but low on the list compared to the completion of SMS Lützow and the ex-Russian light cruisers Elbing and Pillau to be pressed into German service.

Early service 1916-1918

SMS Baden was at least ready for sea trials by 19 October 1916, long after Jutland. Further tests and balic training went on from December 1916 and January 1917 before she was officially commissioned on 14 March. Meanwhile her near sister-ships Sachsen and Württemberg laid incomplete in their respective yards until November 1918. Her first captain, Victor Harder, came from SMS Lützow, recently completed and sunk at Jutland, as well as her crew. Baden became flagship, fleet Commander (Vice Admiral Franz von Hipper) until the end of the war. This was helped by the fact she has been completed with flagship facilities unlike her sister, traduced notably with new accomodations and a distinctive two-decked bridge. There was nothing much to do but training the following months, without notable event.

By late August 1917, Baden carried Kaiser Wilhelm II in a visit to the garrison of the fortified island of Helgoland, escorted by Derfflinger, Emden (ii) and Karlsruhe. She brought him back to Cuxhaven, but while doing so, struck the sea bottom. No visible damage was was later seen so she resumed activity. She was not present, contrary to her sister, in Operation Albion in the Gulf of Riga. She remained idle until early 1918, to the relief of a growingly frustrated crew.

The 23 April 1918 Sortie

In late 1917 already a new tactic emerge, to prey on British convoys to Norway, and oblige the RN to sent escorting capital ships, a bite-size portion of the Grand Fleet that can be destroyed by the Hochseeflotte. On 17 October, Brummer and Bremse intercepted one of such convoys, sinking nine of twelve and two escorting destroyers. This caused a stir in Britain and on 12 December, four German destroyers made shot work of another convoy of five cargo vessels and two British destroyers, sinking all cargoes and of the letter.

Admiral David Beatty was ordered to detach capital ships as planned, so Hipper prepared for a sortie the Ist Scouting Group battelcruisers, reinforced by capital ships like Bayern. The rest of the High Seas Fleet was in stand by on 23 April 1918, in the Schillig roadstead. Admital Hipper had his mark, as usual, aboard Baden and ordered no wireless transmissions to achieve surprise; Later Moltke lost her inner starboard propeller and had to return back, when later when Hipper arrived, he learnt that U-boat intel has been wrong. There was nothing on the convoy route… planned that day. He just had to fold down back to Germany.

On 24 May, SMS Baden again steamed to Helgoland, bringing the new commander in chief of the fleet, Admiral Reinhard Scheer, accompanied by Grand Duke Friedrich von Baden (namesake of the battleship), to visit the fortified island in turn. She was escorted by SMS Karlsruhe. In August 1918, SMS Baden was in drydock maintenance, until Hipper replaced Scheer again at the head of the fleet. Badend maintenance was over on 24 August, and prepared for the last ever major training fleet exercise, on 6 September.

The “doomsday sortie” and Scapa Flow

SMS Frankfurt and Baden, scuttled

SMS Baden was the centerpiece in October 1918 of the last ever planned sortie of the German Navy. It was to be committed an a final major action, a straithforward push to meet the Royal Navy, in part to quell the growing frustration of the crews, seeing inaction for too long, but mostly to try to cripple the RN, hoping to gain a better bargaining chip for future probable peace negociations. It was launched a few days before the armistice but the “crew factor” has not be acertained correctly, and the project massively backfired on the German staff.

War-weary sailors did not shared this final “for honor” stand, and on 29 October 1918, the gathering at Jade roadstead, saw, especially in the night of 29 October, widespread mutinies on many ships. On the 30th for example, the one started on Thüringen extended on Helgoland, just behind Thüringen, until forced to surrender by two loyalist torpedo boats, the crew later taken ashore and incarcerated. Officers noted the mood abord Baden as “dangerous”. Event soon went further as on 3 November, about 20,000 sailors, joined to dock workers and civilians took up arms and attempted free the jailed mutineers. On 9 November, a Socialist red flag was hoisted aboard SMS Baden. At that point, Hipper and Scheer abandoned all hopes for their sortie.

SMS Baden was not cited in the list of ships to be interned during the discussions of the Armistice. She was however substituted for the the incomplete Mackensen, which could not sail. She was not part of the High Seas Fleet departure to Scapa Flow on 21 November 1918 but remained in Germany until 7 January 1919. On arrival, Von Reuter had most of her crew taken off on SMS Regensburg, back to Germany. He knew the crew’s mood and wanted to have reduced, but loyal men under his orders to prepare for all eventuality.

The Royal Navy inspected SMS Baden tow days after her arrival. They hoped to find valuable equipments but found none of the technical and gunnery equipments, all removed before departure. There was therefore no chance for the vessels to commit uinto battle, because of this and the reduced crews, which only left the option of scuttling, prepared for months by Reuter with his officers. Negotiations in Versailles which would decide the fate of the fleet were ongoing and Reuter knew he would never allow his ships to fall into the entente’s hands as war reparations as planned.


Closeup SMS Baden 21 June 1919

New arrived often after days, noytably copies of The Times, so Rear Admiral von Reuter was left in the ignorance of new developments in Paris. He only knew in June, that the armistice was about to end at noon on 21 June 1919, a deadline to sign that also meant his ships would be probaby seized soon after. Von Reuter hoped to see the British fleet leaving Scapa Flow for exercizes at sea, which eventually happened precisely the very day of the deadline, to the amazement of his staff. Little he knew the deadline has been postponed to the 23th. Nevertheless, at 11:20 her ordered a general scuttling, which was promptly made.

Some men from Baden were helped unload a supply ship this morning far from their ship, and were were unavailable to open seacocks, while the remaining skeleton crew was insufficient for this, until man ashore returned. This made SMS Baden the last major warship of the Germany Navy to scuttle herself. Meanwhile, British forces remaining in the harbor managed to secure her, cutting her anchor chains. She derived and ran aground before sinking in deeper water, and soon, Lieutenant Commander Bruce Fraser led an armed party onboard Baden, visibly furious about the event. They managed to prevent firther actions at gunpoint. Therefore Baden was not successfully sunk and therefore she was also quickly refloated, on 19 July 1919, towed to Invergordon base.

Inspected by British Royal Engineers (1919-1921)

Baden inspected by Royal Engineers in 1919

A new strange career started for Baden “under british flag” – in fact she was never recommissioned, nor named, just used as an anonymous hulk for testing purposes. After she arrived in Invergordon with a British crew, SMS Baden was carefully examined by Royal Navy technicians, teams of Royal naval engineers inspected for weeks, months on end, in tunovers and living onboard, so inspect at first her hull in drydock, in great detail, taking measurements and detailed notes of her screws, bilge keels, rudders, to get a picture of her hydrodynamic properties and overall water resistance. They estimated her hull shape at least as good as the British Revenge-class battleships.

The armor system was aso thoroughly examined, as of utmost importance. Indeed that part was considered at the time “top secret” for any navy. The investigation took weeks and would generate a considerable literrature. The main conclusion however, was that the design did not incorporated any lessons from the battle of Jutland. Which was true and evident as their completion was far too advanced for this at the time. Also scrutinzed were detailed of her watertight bulkhead and underwater protection systems. The teams tried pumping and counter-flooding equipment, showing they worked quite well and efficiently.

Also examined in detail were Baden’s main battery turrets, location and working of the ammunition magazines. The tech team went so far as making the whole loading process live test, noting notably how fast the magazines could be flooded (in 12 minutes as it happened). The gunnery school HMS Excellent arrived too to process to complete loading trials, and noted an average 23 seconds, at their amazement. Indeed the RN also prided herself for their record-loading (which cost Beatty dearly at Jutland), but still Baden can load a shell 13 seconds faster than on the Queen Elizabeth class battleships, using the same caliber.

Overall, Commander W M Phipps Hornby, which lived on board Baden for weeks, told in 1969 naval historian Arthur Marder that his own opinion was that he considered the German design overall “markedly in advance of any comparable ship of the Royal Navy”. Once the inspection complete, the admiralty decided to naturally convert the battleship into a gunnery target.

No option was ever given to press her into British service at the time: First, every scripture were to be converted, ammunitions standards were different, parts were unavailable, a special training was required, and the ship was alone, so not to be integrated in the usual five-battleships divisions the RN was accustomed to. The overall picture was that she was more valuable to perform a last telling test instead: Live firing.

In January 1921, after some preparations to more easily locate damage, she was fired upon by HMS Excellent, using the latest armor-piercing (AP) shells developed after Jutland. This was to determine the most efficient ratio of explosives in the detonator caps, as the pre-Jutland shalled tended to fragment when striking heavy armor, not penetrate. The monitor HMS Terror was moored just 500 yd (460 m) away to test point-blank fire with her own 15 in (38 cm) guns and these new shells.

After standard straight trajectories, engineers created an artificial list for Baden by removing of coal and armor from the port side (towards the monitor) so that she would met the shells at an angle (parabolic fire). They also removed when moored, her forward-most gun turret. Terror fired 17 times, testing various ammunitions on Baden. Conclusion was that the new shells were good eneough to penetrate her heavy armor, much more effective as expected than previous models. Heavy seas after the tests caused Baden to sink in shallow waters and teams worked for three months to have her relfoated, towed in drydock and repaired for more service. She was prepared for a second round of testing in August 1921. Meanwhile discussions for the Washington treaty went on, and she was excluded from the talks as a “target ship”, partially demlitarize, through she still was armed and protected as a regular battleship.

The second test round was to take place from 16 August 1921, with this time the monitor HMS Erebus. The latter fired again several shell types, all 15 inches (381 mm). They seemed not to perform however that well, as one failed to explode and two semi-armor piercing models (SAP) shattered on impact. This was not limited to ship to ship tests: To simulate planes dropping bombs, six aerial bombs were placed on board, nose against deck on derricks and detonated remotely. They did little damage, unlike Mitchell’s tests in USA (again against a German battleship).

Probably the most important finding was that Baden’s 7-inch (18 cm) medium armor was easily penetrated by large-caliber shells. From there, the British adopted the US approach of “all or nothing” armor, also from the US. It weight much in their design of the G3 class and Nelsons. They were to receive extremely heavy armor or nothing at all. After the second serie was over, it was decided that Baden was not to be kept, and she was scuttled, in Hurd Deep, under 180 m (600 ft) where she could not cause any threat for maritime trade.

Nautilus class minelayers (1906)

Nautilus class minelayers (1906)

Germany (1906): SMS Nautilus, Albatros

The first two specialized German minelayers

The Nautilus class were two minelaying cruisers planned for the Imperial German Navy, both built by the AG Weser shipyard in Bremen with different designs, at least in appearance. They never operated together, one being kep for training or in maintenance. They laid at the start of WWI a serie of strategic minefields, to protect the German coast and on known pathways for the British Royal Navy.

SMS Albatross was assigned to the Baltic Sea, ambushed by Russian cruisers, damaged and beached after the Battle of Åland Islands in July 1915, in neutral swedish waters, interned. SMS Nautilus participated in Operation Albion in 1917 and modified for amphibious operations in 1918. She was retained as a hulk until 1928, stricken since 1919.

Design

Design development

Nautilus had a clipper bow, while Albatross had a bow similar to contemporary German light cruisers. The ships were armed with a light battery of just eight 8.8 cm (3.5 in) guns and had a capacity of 168–288 naval mines. However they were slow and completely unprotected.

Hull Design in detail

SMS Albatross
SMS Albatross model

the two cruisers varied slightly in their dimensions and shapes: SMS Nautilus had a clipper bow, but still she was shorter, measuring 98.20 meters (322 ft 2 in) long overall for a beam of 11.20 m (36 ft 9 in). Her average draft (deeper aft) was 4.42 m (14 ft 6 in) forward. SMS Albatross was larger, 100.90 m (331 ft) long with a straight bow, 11.50 m (37 ft 9 in) of bream, 4.40 m (14 ft 5 in) of draft. The first displaced 1,975 metric tons (1,944 long tons), 2,345 t (2,308 long tons) fully loaded and her sister ship 2,208 tons normal, 2,506 t fully laden. Nautilus was modernized in 1908 at the Kaiserliche Werft, Kiel with her original stern overhang extended by 2.70 m (8 ft 10 in) so shat she was now 100.90 m (331 ft) long, and her superstructure deck extended further aft.

Hulls construction called for transverse and longitudinal steel frames. Under the waterline, it was subdivided into nine watertight compartments. Below there was a double bottom for 60% of her total length. Superstructyes were close, but diverged. Both had two pole masts with spotting tops, two slightly raked funnels, like the masts, but the mast location and bridge shape diverged. The foremast was behind the bridge on Albatross, but in center on Nautilus. On Albatross it was also higher, her forecastle extending to the base of the main mast. Nautilus had superstructure deck starting aft of the fore mast. The idea was to test both ships with different configurations. Nautilus was essentially a “yacht” in disguise order to operate in a more clandestine way.

Their crew comprised ten officers and 191 enlisted men, and in wartime, extended to 11 officers and 197 ratings. Their small boats fleet included two picket boats, a launch, two yawls, a dinghy, handled with a large derrick at the base of the main mast aft. There was no protection at all, no armour figure are given by any source, including Conways.

Powerplant

The ship’s Propulsion system comprised two 3-cylinder, triple-expansion steam engines. They each drove a single four-bladed screw propeller 3.20 m (10 ft 6 in) in diameter. Four coal-fired marine-type boilers provided steam, each in their own individual boiler room. They were trunked into two closely spaced funnels. Electricity on board came from two turbo generators rated at 90 kilowatts (120 hp)/110 volts each.

Performances wise, their top speed as designed was 20 knots (37 km/h; 23 mph), obtained from an output of 6,600 indicated horsepower (4,900 kW). This was exceeded on trials, Nautilus reaching 20.8 knots and Albatross at 20.2 kn. For range, they carried 200 t of coal. In wartime however, when using auxiliary storage spaces, SMS Nautilus could carry up to 490 t and Albatross even 526 t, giving them a 3,530 to 3,680 nautical miles (6,540 to 6,820 km; 4,060 to 4,230 mi) range 9 knots cruise speed. Steering was done via a single axial rudder and they handled well, with a tight turning radius. However they had a high weather helm and hard time not drifting underway.

Armament


8,8 cm gun (here a FLAK version of 1932)
The primary armament for the Nautilus-class was purely defensive and short range: It consisted in a battery of eight 8.8 cm (3.5 in) SK L/35 guns, all in individual mounts:
Two side by side on the forecastle, four amidships (two on each broadside) and a pair at the stern. A total supply of 2,000 rounds was carried. These 8.8 cm guns had a maximum range of 9,100 m (29,855 ft 8 in) only.
Mines:
Their main asset of course was their mine capacity and facilities: SMS Nautilus carried 186 naval mines, and up to 205 in wartime, 288 for Albatros which hull was better shaped to carry more. German naval mines of WWI were of the following type: Type I Moored Hertz horn contact mine (Total mass 560 lbs./254 kg, Diameter 31.5 inches/80 cm, Wet gun guncotton 180 lbs. 81.6 kg explosive charge.

Nautilus 1918 Conversion
In 1918, Nautilus was rearmed with two 7.6 cm (3.0 in) guns, four 2 cm (0.79 in) anti-aircraft guns, twenty-four machine guns, two flamethrowers, and four mine-launchers, in addition to her normal capacity of mines. Her new armament was intended to allow the ship to support amphibious operations.

Prewar service

SMS Nautilus was launched at AG Weser shipyard on 28 August 1906 (laid down as “mine steamer A”, completed and commissioned for sea trials on 19 March 1907. From 25 May she starting training for for mine warfare in Cuxhaven. She took part in the annual fleet maneuvers in 1906, 1907 and 1908 and decommissioned as her sister ship Albatross took her place in peacetime. In 1909–10 she was modernized at the Kaiserliche Werft, Kiel. Her stern overhang was extended by 2.7 m (8 ft 10 in), her superstructure deck extended further aft.

On 23 January 1910, SMS Nautilus retuned to minelaying training and participated in the 1910 annual fleet maneuvers. After a new overhaul in Kiel until 27 January 1911 she returned to training and on 4 April was replaced again by Albatross. She later experimented with minesweepers in the North Sea and took part in the annual fleet exercises. On 30 October 1911, she was replaced by light cruiser Arcona and remained in reserve until the crisis developed in the Balkans, replacing on 5 June 1914 the older minelayer SMS Pelikan in long overhaul.

Wartime Operations

From July 1914 she was reclassified as a coastal defense mine cruiser and temporarily sent to the Baltic , laying defensive minefields in the path of the Russian Baltic Fleet. On 25-26 August, back to the west, and teaming with her sister ship, she layed a minefield off the Humber and Tyne on the English coast. That risky operation was performed by night, and two minelayers proceeded independently, covered each by a light cruiser and destroyers.

SMS Nautilus was protected by Mainz and she laid two mine fields 5 nmi (9.3 km; 5.8 mi) long across the known usual merchant pathways. When back, her group spoted and sank six British trawlers. SMS Nautilus, Albatross and the auxiliary minelayer SMS Kaiser later laid a defensive minefield on the Bight on 9–10 September. On 14 October 1914, protected by SMS Kolberg, she was to lay another minefield in the North Sea, off the Firth of Forth, but as they spotted the enemy off the Dogger Bank, they broke off.


Colorized photos of the SMS Albatross underway
In April 1916, SMS Nautilus was sent again in the Baltic after the modern modern SMS Brummer entered service, dedicated to western operations. The rest of 1916 and early 1917 were relatively uneventful with few sorties but she laid a serie of minefields for tactical funneling. In October 1917, she was assigned to the VI Scouting Group (light cruisers Kolberg, Strassburg, Augsburg, aviso Blitz), for Operation Albion. She stayed outside the Gulf of Riga until Russian forces were cleared off from the area and she then sailed off Arensburg on 18 October to lay defensive minefields. On the 21 she was planned to lay mines west of Schildau but it was found too shallow and she transferred her mines to smaller vessels of the II Minesweeper Flotilla to perform the mission, and she was later based in Arensburg.

In 1918, her armament was modified to act as an amphibious support ship. She received two 76 mm (3.0 in) SKL guns, four 20 mm (0.79 in) AA guns, 24 machine guns and two flamethrowers, plus four mine-launchers in addition to her mines. In February 1918 she joined the Sonderverband (Special Unit) tasked of cmbating the anti-communist faction during the Finland’s civil war. On 30 April 1918, Konteradmiral Ludolf von Uslar made Nautilus his flagship, but the operations ceased and the unit was disbanded in May. The minelayer stayed in the northern Baltic and patrolled off Åland island until December. She was decommissioned.

The Treaty of Versailles excluded her from the new Reichsmarine and instead she was stricken on 21 March 1919, in Kiel and used from 1921 as an unarmed storage hulk in Bremen, (“Hulk I”) from 1923, then “Hulk A” (April 1928) in Bremerhaven, with the Training Inspectorate. She was sold and BU in Copenhagen.

SMS Albatros

SMS Albatros stranded 1915
SMS Albatross was built at AG Weser shipyard, Bremen, laid down as “mine steamer B”, 24 May 1907, launched on 23 October and commissioned for sea trials on 19 May 1908, until 25 July. She took the head of her minesweeping unit while the older SMS Pelikan was under overhaul and took part in the annual fleet maneuvers. On 26 October 1908 and 1909 she became a training ship in Cuxhaven. In 1910 she was ovehauled at the Kaiserliche Werft and modernized, with her mine-launching equipment moved to the upper deck. In 1911, she rammed the steamer Wartburg and needed three weeks repairs; In September she was sent into the Baltic Sea. In 1912, 1913, and early 1914 she had the same same routine.

In July 1914 as a “mine cruiser” she laied defensive fields in the Baltic Sea and later with Nautilus off the Humber and Tyne. Albatross’s group comprised SMS Stuttgart and on her return, hit some of the six British fishing vessels sunk. By June 1915 she was in the Baltic with the auxiliary minelayer SMS Deutschland under Konteradmiral Albert Hopman’s command. Her first operation, codenamed V, was performed on 20 June escorted by SMS Roon, Prinz Heinrich, Prinz Adalbert, Augsburg, Lübeck, she laid a large minefield off Bogskär. Later she laid 350 mines escorted by Prinz Adalbert, Prinz Heinrich, Thetis (operation VI), screened by eight torpedo boats. She was based in Neufahrwasser all this time.

Battle of Åland Islands

For operation, VII (29-30 June night) she was escorted by Roon, and five TBs, meeting out of the Vistula later Kommodore (Commodore) Johannes von Karpf—Lübeck’s ships and more TBs. She laid her minefield off Bogskär and later Roon and Lübeck separated to guard a channel between minefield, while Albatross proceeded north to Bogskär, laying 160 mines. Augsburg went south to join Roon and Lübeck while Kdt. Karpf received via wireless a report over her position, intercepted and decrypted by the Russians, which were about t lauinch a bombarding sortie on Memel the following day.

Led by the armored cruiser Rurik four cruisers sorties on 1st July, trying to ambush the Germans, but Karpf dispersed his force and Albatross, Augsburg plus three TBs speamed to Rixhöft, the remainder to Libau. At 06:30 on 2 July, lookouts from SMS Augsburg spotted the Russians and Karpf ordered Albatross to seek refuge in neutral Swedish waters, the others using their speed to escape and possibly draw the Russians on Roon and Lübeck. However soon the latter catch up with them and turned to port to bring their full battery to bear, firing from 8,000 m (26,000 ft). Bogatyr and Oleg concentrated on SMS Albatross, but this was innacurate due to Heavy fog.

Soon, the monelayer was found alone, with all four Russian cruisers shelling her. At 07:20, she was hit and more were to come as the range closed. At some point she was close enough to replicate with her 8.8 guns, with little effect on the armoured cruisers. Her forecastle was soon crippled, foremast knocked down, conning tower destroyed, with the staff inside but eventually at 07:45, she entered Swedish territorial waters. However in violation of international laws, the Russians pressed on and kept firing for twenty minutes, stopping only at 08:07, after Albatross reached Östergarn Sound. She was badly damaged, listing heavily to port and her captain ordered her to be beached and made preparatios to evacuate and scuttling.

Hopman considered sending a torpedo boat for towing Albatross, but the Russian vessels were a serious thrat. Prinz Adalbert and Prinz Heinrich reinforced Karpf’s ships and sailed out to rescue Albatross, but en route, HMS E9 torpedoed Prinz Adalbert, so making Karp break off the operation. Albatross was interned by Sweden for the remainder of the war, never repaired and not scuttled as the Russian would not dare approaching. 26 German sailors were buried east of Östergarn Church and two at Björke cemetery. The survivors were interned in Roma, and Blåhäll, Tofta. The Swedish salvage company Neptun refloated Albatross on 23 July, towed to Fårösund, then Oskarshamn, to be interned, only returned (as her crew) to Kiel in January 1919, and decommissioned on 23 January, stricken on 21 March, then sold for BU in Hamburg.

Dresden class cruisers

Dresden class cruisers

Light Cruisers SMS Dresden, Emden (1908)

Two famous ships

The Dresden class followed the Königsberg class, but improved in size and speed a bit. Launched in 1907-1908, their fates were among the most interesting of the war: Both Königsberg and Dresden were part of the overseas squadrons of the Kaiserliches Marine in 1914. Dresden was in Mexican waters and has to quickly head for the eastern Indian Ocean via Good Hope, and became one of the most famous German commerce raiders, joining Admiral Von Spee’s squadron at the Coronel battle, duelled at the Falkands with Kent and Glasgow, but ended scuttled in the maze of islands of Chile in March 1915. Emden was in China, heading with Graf Spee’s East Asia Squadron and was detached for independent raiding in the Indian Ocean, also attacking Penang and the Cocos Islands, but lost a duel to HMAS Sydney. The Crew then managed to get back to Germany, in a true odyssey which was turned into two movies.

Design

Profile overview in a German publication
Profile overview in a German publication

The origins of the design could be found in the 1898 Naval Law, authorizing construction of no less than thirty new light cruisers. The Gazelle class has been the first, developed into the Bremen, and then Königsberg class. Both had many incremental innovations and improvements over globally the same basic design. The two Dresden class just proceeded with the same caution, design-wise. Ordered in the 1905–1906 construction program, they were not just a repeat of the Königsberg but consituted an improvement. Keeping the same main battery they had a slightly greater displacement, the internal machinery space be generous enough to accommodate an additional boiler, and thus, increase engine power. Like on the previous class, engineers differentiated both vessels by testing different machinery: VTE for SMS Emden and steam turbine for the lead ship, in order to compare their performances. But it was the last and decisive test of tht kind. After this, the admiralty decided from then on all cruisers would be fitted with turbines only.


The previous Bremen class – Illustrated London News, 20 March 1915

These cruisers were built at Blohm and Voss shipyard (Dresden) and Kaiserliche Werft, Danzig (Emden). They were launched in 1907-1908, and entered service in 1908-1909. Larger by one meter, wider by 30 cm and heavier by 200 tonnes, they were slightly faster (23.5 and 24 knots compared to 23), but possessing the same firepower, they really shows this almost timid incremental process. The next Kolberg class (1909) were much larger and faster, and better armed.But the true really first innovative designs were the Magdeburg (1912).

Hull & general characteristics


Model of the Emden: Note she was not in overall grey in 1914


Model of the Dresden

Both ships had this characteristic three-funnels silhouette. Their hull measured 117.90 meters (386 ft 10 in) long at the waterline and 118.30 m (388 ft 1 in) long overall, for a beam of 13.50 m (44 ft 3 in), with a draft iif 5.53 m (18 ft 2 in) forward, greater aft. Standard displacement was 3,664 metric tons, reaching 4,268 t (4,201 long tons; 4,705 short tons) fully loaded. Construction called like previous ships for transverse and longitudinal steel frames. They had a transverse metacentric height of .59 m (1 ft 11 in), which was reasonable. This ensure a gentle, predictable motion.

Dresden and Emden carried 18 officers for 343 enlisted men. Like all vessels of that era, they carried many small boats, a fleet including a single picket boat, a barge, a cutter, two yawls and two dinghies. The last four were mostly used for physical training, sailors making regattas against themselves or other crews, and to carry personal, or land armed parties, somehing which will proved handy for Emden in two occasions. The steam picket boat was the standard laison all-weather vessel used to carry officers to port or used to carry dispatch to other ships in the fleet at sea. The barge was used for coaling and carry supplies, and the cutter as a fast dispatch vessel with ample sail. It was used generally by captains as their own leizure boats when not in service;

Protection


Jane’s 1914 Dresden class diagrams and drawing

Their armour was slightly improved, with the deck and turrets protected by 50 mm (2.5 in) to 80 mm (3 in) of armor: It was thicker on the slopes either side.
To be more precise, the main armoured deck at the waterline reached up to 80 mm (3.1 in) amidships with sloped 50 mm (2 in) thick, but tapered down to 30 mm (1.2 in) aft and 20 mm (0.79 in) toward the stern.
The main belt was about 30 mm thick (1.8 in), only on the central section, between the forward bridge and extending to the aft gun. An extra stray of armour of 50 mm was fitted over the machinery spaces aft.
The conning tower had walls 100 mm thick (4 in) with a saller communication tube going two decks below.

The gun masks were 50 mm thick (2.5 in) and in addition the forward and aft guns were protected by a partial structure. The four on the corner of the main battery were inside casemates.
The hull was subdivided under the waterline into thirteen watertight compartments, with a double bottom below, extendeding for 47% of the length of the keel.

Machinery


Binnacle of Emden, salvaged in Australia

Propulsion relied on two propellers, and they possessed three 4-cylinder engines, 12 standard boilers, for a total of 13,500 hp, and top speed of 23.5 knots.
The Dresden were reputed to be good sea boats, but cranking and rolling up to 20° in heavy weather, being also very wet at high speeds. they also suffered a slight weather helm. But they turned tightly, and were very maneuverable and agile. Their relatively small size and hull design made speed losses on a hard turn limited to 35%, which was very reasonable for this class of ship.

10.5 cm SK/L40 salvaged on the Emden’s wreck by the Australians after the war, AWM.

Main armament: Ten 105 mm (4.1 in) (4 in) SK L/40 guns, which were placed as follows: Two side by side on the prow and bow, and the others six on the sides, the two amidship with their own masks and the remainder in casemates. They reached 12,700 m (13,900 yd) and were supplied with 1,500 rounds of ammunition (150 per gun).

Secondary armament: Both cruisers were armed with eight 5.2 cm (2 in) SK L/55 guns, with 4,000 rounds of ammunition. This was an improvement over the previous Königsberg, which had none. The danger indeed of torpeod boats was recoignised as it was estimated that the main guns had not enough rate of fire to deal with them until reaching critical distance. The 5.2 cm had a short career in the Kaiserliches Marine. The next Kolbergs had only four of them, and the Magdeburg class has none, but gaining the excellent 8.8 cm SK L/45 from 1917, which became the de facto standard light gun in the Navy.

Torpedo armament: Like all previous cruisers, the Dresden class were provided with two 45 cm (17.7 in) torpedo tubes. They were submerged, fixed in the broadside, with five reloads.

SMS Emden

SMS Emden

Interwar service

SMS Emden entered service in 1909, taking part in autumn manoeuvers and escorting the imperial yacht Hohenzollern with the Kaiser aboard. She was decommissioned after completing trials and on 1 April 1910 assigned to the Ostasiengeschwader (East Asia Squadron) in Tsingtao, 1897 Kiautschou concession (China). She left Kiel on 12 April 1910, but made a goodwill tour of South America (12 May, Montevideo to meet Bremen, Ostamerikanischen Station), and headed for Buenos Aires, to participate in the celebrations of the hundredth anniversary of Argentinian independence. They passed the Horn and stopped in Valparaíso, and separared off Peru, as Emden headed for the Pacific, stuggling at frst to get good quality coal.

Emden carried 1,400 t of coal from the Chilean naval base at Talcahuano and was en route on 24 June, making her long-term shakedown cruiser along the way. Everything was noted on a report for future cruiser designs. She met severe weather along the way, notably off Easter Island, stopped in French Papeete, Tahiti, and made the next 4,200 nautical miles trip to German Samoa (22 July) to meet the East Asia Squadron (Konteradmiral Erich Gühler).


The crew of SMS Emden before the war

In October, the squadron headed for Tsingtao and for the first time, Emden entered the Yangtze River, exploring it from 27 October to 19 November and stopping in Hankou. Next she headed to Japan, stopping at Nagasaki and was back in Tsingtao on 22 December, and a refit, interrupted by the the Sokehs Rebellion at Ponape in the Carolines. She was ordered there, departing on 28 December, and joined by SMS Nürnberg from Hong Kong.

They met at Ponape the old Cormoran and all three bombarded rebel positions, completing the mission by sending a large combined landing force, which were added to the colonial police troops. This ground offensive was made on mid-January 1911 and by late February the revolt was suppressed. On 26 February the old cruiser SMS Condor arrived arrived to relieve them and Emden departed on 1 March for Tsingtao, via Guam, arriving on 19 March and starting her overhaul.

Emden in Tsingtao, early 1914

By mid-1911, she toured Japan and accidentally rammed a Japanese steamer, during a typhoon, which caused enough damage to sent her in drydock in Tsingtao. Next she was ordered in the Yangtze to protect Europeans as the Chinese Revolution broke out on 10 October and by November she was placed under ordered of Vizeadmiral Maximilian von Spee. The cruiser won the Kaiser’s Schießpreis for her gunnery marksmanship, in the whole East Asia Squadron. She was sent off Incheon to assist the steamer Deike Rickmers, grounded, and by May 1913 Karl von Müller took command, soon promoted Fregattenkapitän. In mid-June she cruise German colonies in the Central Pacific. In between she was sent to Nanjing to protect nationals during a fight between Qing and revolutionary forces and in August, she was attacked by rebels believing she sided with Qing. Her gunners returned fire, which was efficient.

Wartime service

In August 1914, Commander Von Müller decided to leave the base quickly so as not to be cornered by a superior forced and to join Von Spee’s squadron in the Pacific through the Strait of Korea. In between the spotted and caught a Russian liner, the Riasan, take the crew in custodu, recoaled and scuttled the ship. Müller learnt in between Admiral Jerram’s squadron had arrived off Tsing tao, Von Spee then having no other option but to make for home, or die trying. The Japanese went at war in turn on 23 August but after a conference between Spee and Müller, Emden was to be left in the Indian Ocean as a diversion, while the squadron was steaming to the Cape Horn.

By leaving Spee, Emden started a formidable raiding spree that would enter the annals of the Kaiserliches Marine as one of the most successful. After roaming off Indonesia, with a fourth fake funnel built to look like a British cruiser, she missed her coaler, the Markomannia on September 8th but persuaded the captain of the neutral Greek coaler Pontoporos to supply him. Later she seized the freighter “Indus” loaded with food a welcome addition.

The latter was abandoned as too slow, the crew transferred to Markomannia. Next, Emden captured the cargo “Lovat”, the Kabinga, the small coaler Killin, the large steamer SS Diplomat. Next he sized the Italian Loredano, sunk the coaster Trabboch, but was betrayed by a communicaion by the captain of the Loredano, passing his position to the Admiralty, that scrambled all available forces.

Leaving her small fleet, Emden loaded all she could and started to steam fast, now trying to attack British ports on the Indian coast. On September 22, she raided the oil tanks of Madras, and the shelled Colombo, also sinking a large transport of sugar.

Next, she raided Diego Garcia, an important British colonial base, on the Mauritius islands. Von Müller briefed his staff of not to divulgate there was a state of war, and camed as for a “courtesy visit”. He was well received by the Governor and be able to replenish serenely. By wireless however he soon learned about the arrival of British vessels, and left the island precipitately, leaving behind the Markomannia. She hid behind the island of Minnikoy, sinking five English steamers. Eventually Von Müller decided to leave the area and rally Von Spee via Malacca strait.

The Emden arrived on the 28th of October before dawn off Georgetown, Penange, all light shut and surprised four French ships at anchor, including the cruiser d’Iberville. One destroyer, the Mousquet, was patrolling nearby but failed to see her. The Russian cruiser Jemtchug was also there, a more deadly opponent. Emden opened fire from the best position, at point-blank while hoisting the flag of war and launched a torpedo on the Jemtchoug, whichremained afloat but was crippled by artillery. The latter counter-fired but without effect and she launched a second torpedo, apparently striking her ammunition store. The Russian cruiser blew up and sank. D’Iberville came, but was fooled by a change of flag, and reassuring morse about an accidental explosion, until her captain saw the Emden fourth fake funnel trembling in the wind, realizing his error. But it was too late, with the Aviso’s light artillery and engines cold, she could do little before Emden escaped.

Steaming for the other side of the harbour she captured the steamer Glen Turret, but was surprised by the French destroyer Mousquet, which aptain decided to make a torpedo run. Emden’s fire battered the French TB during her approach and she eventually capsized and sank. A second destroyer approached, but again Emden managed to escape. She was chased off by the French destroyer for hours, until running out of coal.

The Cocos Islands Battle and return home

The Emden arrived next in the Cocos Islands, one of which had a radio station that Von Müller needed to destroy, in order to refuel there. When the cruiser arrived, a message was sent nevertheless, intercepted by the Australian cruisers HMAS Melbourne and Sydney escorting a convoy nearby. The two ships steamed towards the Cocos Islands just half an hour later, while 50 of the crew (a demolition landing party) just were now on the island, including the second Von Mücke, proceeding to the destruction of the radio station of Direction Island.

HMAS Sydney soon spotted and engaged Emden, with her numerous longer range, hard-hitting 6-in guns. With a reduced crew, Emden could not fleet not answer effectively and she was soon blasted. Her telemetry was destroyed, and her guns silenced one by one as the funnels were falling. Soon, this was over.

Von Mücke’s company saw the unequal action from the roof of one building. They greeted the apparent 18 hits by Emden on Sydney (killing three, wounding 13) but she ended ablaze and dead in the water after 670 rounds spent, 100 claimed on target. Von Müller managed to beach her on the reefs of North Keeling, saving most of the remaining crew. Captain Glossop sent an injunction to surrender and two warning salvoes until a German white flag was hoisted. Emden lost 133 officers and men in this fight, out of 376. The remainder left the ship, which was scuttled properly.

Sydney left quickly to head for Direction Island and land her own company of riflemen to engage Von Mücke’s men, but the latter in between seized the governor’s schooner, Ayesha, and sailed to the island of Padang, Dutch East Indies. Von Müller’s men were later made POW, some interned in Australia, the others in Malta, back home in 1920. The rest of the trip was near-legendary. Von Mücke managed to conduct the Ayesha to Sumatra on November, 7, later waited and embarked in a German steamer for Yemen. They reached Bab-el-Mandeb, crossed all the Arabian peninsula and arrived in Constantinople in june 1915. Latter they took the train and reached in June 1915 the fatherland, greeted as heroes. The rampage of Emden would span 30,000 nautical miles (56,000 km; 35,000 mi), added to the formidable tally she could claim.

SMS Dresden

Light Cruiser Emden

SMS Dresden, ordered as “Ersatz Comet” in Blohm & Voss shipyard (Hamburg), was laid down in 1906, launched on 5 October 1907, commissioned on 14 November 1908. On 28 November during her sea trials she collided with the small Swedish coaster Cäcilie off Kiel. Her starboard propeller shaft however was moved 1.2 in off-axis, requiring six months of repairs. Sea trials only resumed 1909, leading to a turbine accident, having her in repairs again until September.

Dresden had botched trials, declared over on 7 September by an impatient admiral, and she made her shakedown cruiser while visit the United States, representing Germany at the Hudson–Fulton Celebration (New York) in company of the cruisers Hertha and Victoria Louise as well as Bremen, sailing on 11 September, arriving at the gathering point at Newport, and arriving in New York on 24 September. She stayed there until 9 October and was back in Germany on 22 October.

Next, SMS Dresden was assigned to the reconnaissance force, High Seas Fleet and started her peacetime routine of squadron exercises alternated with training cruises and yearly fleet exercises. On 16 February 1910, really unlucky by this point, she collided with SMS Königsberg. The one caused again significant damage and furter repairs in Kiel for eight days. After visiting Hamburg on 13–17 May she was assigned to the Training Squadron on 14-20 April 1912 with Friedrich Carl and Mainz. She earned the 1911–12 Schießpreis (Shooting Prize) for light cruisers. Until September 1913 she was under orders of Fregattenkapitän Fritz Lüdecke, also her wartime captain.

dresden 1912 On 6 April 1913 she sailed with SMS Strassburg to the Adriatic Sea and the Mittelmeer-Division (Mediterranean Division), flanking SMS Goeben (Konteradmiral Konrad Trummler). By late August, Dresden was ordered back to Kiel and sent to the Kaiserliche Werft for an overhaul until December. Her January planned Mediterranean service was cancelled by the Admiralstab and she was sent to the North American station instead, due to the Mexican Revolution. She replaced Bremen, due for replacement by SMS Karlsruhe. Dresden arrived off Vera Cruz on 21 January 1914, still under Erich Köhler, watching over German interests there, and she was later recalled and replaced by SMS Hertha, on a training cruise for naval cadets, and soon Bremen, watching over the evacuation of European nationals on the German HAPAG liners.

Dresden and HMS Hermione rescued also 900 American citizens trapped in the Vera Cruz hotel, transferred to US warships, by far the largest contingent there. The German consul in Mexico City asked for a landing party from Dresden, created with a Junior Petty Officer and ten sailors armed with two MG 08 machine guns. On 15 April 1914, the cruiser headed for Tampico, Mexico’s Gulf coast. In the meantime, the SS Ypiranga arrived in sight of Mexico with small arms for the Mexican dictator Victoriano Huerta. But the United States put in place an arms embargo in between, and they intercepted Ypiranga on 21 April. As she was German, Dresden arrived to confiscate officially the merchantman, and officially carry out German refugees out of Mexico, but delivering the weapons and ammunition nevertheless.

On 20 July 1914 the Huerta regime was toppled and SMS Dresden carried Huerta and Aureliano Blanquet (Vice Pdt.) and their families to Kingston in Jamaica, where they were granted asylum. Köhler learned there the situation degrading in Europe and set sail as she needed a refit. She met SMS Karlsruhe in Haiti and on the 31st, under captain Lüdecke, she was prepared for Handelskrieg (commerce raiding war) in the Atlantic instead.

Firing on the steamer SS Mauretania, August 1914

Dresden sailed south under radio silence and was conformed the state of war on 4–5 August, so she started her operations in the South Atlantic, and Brazilian coast. Close to the mouth of the Amazon River, she intercepted her first British merchantman on 6 August, SS Drumcliffe. Next she refuelled with the German collier SS Corrientes and sailed to the Rocas Atoll, escorting the HAPAG steamers Prussia, Baden, and Persia. She set sail for Trinidad, and intrcepted on her way the SS Hyades, then captured the British collier SS Holmwood (24 August). In Trinidade, she met the gunboat Eber and several steamers, replenishing.

On 26 August off Río de la Plata she caught two more British steamers. However due to her worn out condition at this point, her captain decided to stop operations and on 5 September, went to Hoste Island for urgent engine maintenance. Informed by the HAPAG steamer Santa Isabel’s captain from Punta Arenas, on 18 September Dresden’s captain decided to transit via the cape horn, and in the Pacific, she stopped in the Juan Fernández Islands, contacting Leipzig. On 12 October she was affected to Vizeadmiral Maximilian von Spee’s East Asia Squadron, coaling at Easter Island.

On 18 October she joined her sister ship Emden and the East Asia Squadron in a rampage along the South American coast, down to Más a Fuera island (26 October), escorting the auxiliary cruiser SS Prinz Eitel Friedrich and the SS Yorck and SS Göttingen to Chile. While Off Valparaiso they received intel about a British cruiser at Coronel, later identified as HMS Glasgow, forced to leave port due to neutrality rules. However he did not knew he was with the 4th Cruiser Squadron (RAdm Cradock) with Monmouth, Good Hope and MAC Otranto. This encounter led to the battle of Coronel.

On 1 November, at around 16:00, SMS Leipzig spotted first smoke from the British squadron, and the two squadrons closed the distance until fire broke out at 18:34, at 10,400 m. Dresden fired on Otranto making her fled at the third salvo and claimed to have started a fire. Next, she shifted on Glasgow, already duelling with Leipzig. She made five hits and at 19:30, was ordered to launch a torpedo attack. She increased speed in the heavy weather and deterioating sight, briefly spotting Glasgow withdrawing. Dresden met Leipzig and near fired on her in the semi-darkness. By 22:00, with other light cruiser she was deployed in a searching column but never took sight of the British again. She was not hit a single time.

On 3 November Scharnhorst, Gneisenau and Nürnberg sere ordered back to resupply in Valparaiso under neutrality laws (three belligerent warships only) while Dresden and Leipzig remained with the colliers in Más a Fuera. Spee was back on 6 November, sending in turn Dresden and Leipzig to Valparaiso, arriving on 12 November and back on the 18th. On the 21th, the squadron sailed to St. Quentin Bay (Gulf of Penas) to coal while the British Amiralty ordered Vice Admiral Doveton Sturdee south with the battlecruisers Invincible and Inflexible, en route from 11 November. They arrived in the Falklands on 7 December, soon joined by the Cornwall, Kent, and Carnarvon, Glasgow and Bristol. The trap was set.

Spee left on 26 November and caught on 2 December the Canadian sailing vessel Drummuir carrying 2,750 t of excellent Cardiff coal. The squadron recoaled at Picton Island, and Spee made a council on 6 December, planning for an attack on the Falklands, to eliminate the large British wireless station there and all coal stocks, despite Lüdecke and Leipzig, Nürnberg captains opposition, preferring to raid La Plata area. Seniority won and ordered were given.

On 6 December afternoon, the squadron departed Picton Island and on 7 December arrived off Tierra del Fuego, and then sighted the Falklands at 02:00. At 05:00, Gneisenau and Nürnberg were detahced to send landing parties and were en route when they spotted at 08:30 smoke raising from Port Stanley’s harbor. Spee realized his error and gave orders to fleet eastwards, rejoining his squadron at 10:45, leaving the German auxiliaries to hide in the islands off Cape Horn. They were soon taken in hot chase by the British. At 12:50, the battlecruisers catched SMS Leipzig and Spee ordered the three light cruisers to escape south, while he would engage the British with the Scharnhorst and Gneisenau. Sturdee then ordered his armored and light cruisers to chase off the German light cruisers. While Spee died in his gallant fight, Dresden’s worn out turbine could not out-run her opposition and Lüdecke wanted her to hide in the islands off South America.

On 9 December, she rounded the Cape Horn and entered the Pacific, first dropping anchor at Sholl Bay with just 160 t of coal in store. Oberleutnant zur See Wilhelm Canaris convinced the Chilean naval representative a extra 24h delay to stock extra coal at Punta Arenas, starting on 12 December. She embarked 750 t from a German steamer and the admiral staff hoped she could make a run through the Atlantic and head for home. But still, her turbines would not allow this and Lüdecke wanted to continue his raiding spree in the Pacific, via Easter Island, then heading for the Solomon Islands, Dutch East Indies and operating in the Indian Ocean.

After taking on board 1,600 t of coal on 19 January, she headed for another hideout, making maintenance whith whatever available. On 27 February underway, she captured the British barque Conway Castle, south of Más a Tierra, was resupplied by the German liner Sierra Cordoba, and made another coaling at Juan Fernández Islands. On 8 March, while underway in dense fog, lookouts spotted HMS Kent, engines off, just 15 nautical miles away. Both raised steam, but Dresden recoignising she was a greater adversary managed to escape after a five-hour chase. This depleted her coal stocks and further deteriorating the state of her engines until Lüdecke estimated his ship was no longer operational, and he wanted her to be interned instead. He set sail to Más a Fuera, Cumberland Bay, later confirmed by the German Admiralty, and contacting Chilean officials.

On 14 March however, Kent and Glasgow arrived off Cumberland Bay, but Dresden was stuck. Lüdecke signaled she was no longer a combatant but the British disregarded this and HMS Glasgow soon opened fire, even in violation of Chile’s neutrality, soon joined by Kent. German gunners just had to time to be on battle station and fired three shots until British gunfire knowked them out. Lüdecke signalled “Am sending negotiator”, dispatching Canaris in a pinnace while Glasgow went on shelling Dresden. Lüdecke soon raised the white flag at last. Canaris met Captain John Luce, receiving terms of unconditional surrender, the latter perotesting they were already interned by Chile and saked for scuttling instead. This was done at 10:45 with charge detonated in the bow’s ammunition magazines, crew evacuated. Dresden sank after 30 minutes and as it did, the second scuttling charge exploded in the engine rooms.

The crew mostly managed to escape, 8 sailors had been killed and 29 wounded in the shelling. The British MAC HMS Orama took the most wounded to Valparaiso. The officeres eventually picked up Chilean warships, then a German passenger ship to be interned in Quiriquina Island. Canaris however would escape on 5 August 1915, making it back to Germany two months later and on 31 March 1917, others escaped and captured the Chilean barque Tinto, reaching in turn the fatherland after 120 days. The wreck was inspected in 2002.

Bremen class Cruisers (1903)

Germany (1902-04) Bremen, Hamburg, Berlin, Lübeck, München, Leipzig, Dantzig

The Bremen class: More than just improved Gazelles

After the satisfactory deign of the Gazelle class (IV class, 11 ships 1898-1902) it was decided to repeat the type with many improvements: Larger to house a better powerplant, faster, better armed, and better armored. They were also the first cruiser named after cities, which became standard from this point, rather than mythological figures.

The Bremen class comprised seven light cruisers, all built in the early 1900s as SMS Bremen, Hamburg, Berlin, Lübeck, München, Leipzig, and Danzig. Like the previous Gazelles, their main battery comprised ten 10.5 cm SK L/40 guns plus two torpedo tubes. These ships served in a variety of roles from colonial cruiser to fleet scout and training ship in peacetime. Bremen and Leipzig served in the American and Asian stationsthe others alternating betwe the Baltic and North sea, training with the High Seas Fleet. In August 1914, Leipzig was in the Pacific (East Asia Squadron), fought at the Battle of Coronel and sink later at the Battle of the Falkland Islands. SMS Bremen hit a Russian mine in the baltic, December 1915, the other five surviving, seized by Britain as war prizes, sold for scrapping except Hamburg and Berlin, which ended as training cruisers of the new Reichsmarine, then barracks ships until 1944, Hamburg sunk by British bombers, Berlin scuttled after the war with Chemical weapons onboard.

Design development 1898-1900

The German parliament’s 1898 Naval Law authorized construction of no less than thirty new light cruisers, to be fufilled by 1904 (do in six years). This implied two cruisers per fiscal year. An amendment passed in 1900 increased it to three to keep up the pace as new programs came in. That year, Admiral Alfred von Tirpitz, the new head of the Reichsmarineamt or Imperial Naval Office, favoring home waters to foreign stations.

Since the Gazelle-class already filled the requirements for the first ten 1898 Naval Law ships, most affected to foreign stations, the remainder were to be redesigned as the Bremen class mostly to serve in home waters, but still with a dual role of peacetime station cruisers and training vessels, but in wartime, fleet scouts.

Many improvements were to be ported over the Gazelle class, in size and speed. The requirement for “fleet scout” meant a greater speed, in turn traduced into more internal space for a more powerful propulsion system. With more boilers, a third funnel appeared, while to stand in combat against Royal Navy light cruisers, the armor deck was massively thickened. While in 1900 design work progressed, Tirpiz, informed of development on new German turbines to be ready by 1901 instructed the construction department to fitting one in the newly built cruisers.

He also wanted to compare performances this way between the Gazelle’s triple-expansion steam engines and the Bremen class, and to have on the longer term, an all-turbine powered home water fleet, as well as comparing between turbine manufacturers with same-class vessels. The Kaiser approved his decision in the end, but as design work was finished and construction was already underwat, limited on the fourth ship of the class, SMS Lübeck. t was approved on 20 January 1903.

The Bremen class marked a change not only in naming conventions, greeting old Hanseatic League cities but also ex-German states with major cities in Bavaria and Saxony, and of course the new German capital. The Bremen were the direct predecessors of the Königsberg class, very similar, with the same armament but improved incrementally in many ways, but one equipped with turbines, the others with triple-expansion steam engines.

Design of the Bremen class

A Bremen class cruiser underway

The Bremen-class hull was longer than the previous Gazelle, with 110.6 meters (362 ft 10 in) long at the waterline, 111.1 m (364 ft 6 in) overall, versus 105 m. They also had a superior beam at 13.3 m (43 ft 8 in) versus 12.20m for the previous cruisers, and a draft of 5.28 to 5.68 m when fully loaded (17 ft 4 in or 18 ft 8 in) versus 4.11 up to 5.38 for the former.

These larger dimensions traduced into a displacement of 3,278 metric tons (3,226 long tons) as designed, an increase of 700 tons or about 1/6, which was quite an increment. The Bremen class displaced also and between 3,652 to 3,816 t fully loaded (versus 3,500 on the last Gazelle class). They had flush decks and a pronounced ram bow while the previous Gazelle had a stepped hull with forecastles. For construction, they used the same basic scheme of transverse and longitudinal steel frames.

These ships were generally reputed good sea boats, rolling up to 20° but at least with a gentle motion and predictable speed. They appeared very wet at high speeds, “plowing” heavily and having slight weather helm. Their rudder allowed them still to turn tightly and stay agile. In a hard turn, their speed fell up to 35 percent. Transverse metacentric height was 0.58, up to 0.61 m (23 to 24 inches). In standard they carried a complement of fourteen officers and from 274 to 287 ratings, later increased to 19 and 330 in WWI. Their small service boats fleet included a steam picket boat, a pinnace, two cutters, two yawls, and one dinghy.

Armour protection

Bremen-class_plan_and_profile_drawing-Brasseys
Bremen-class plan and profile drawing Brasseys

The major difference for protection compared to the previous Gazelle, was their deck armour, which went up to 80 mm (3.1 in), sloped down to join the unarmoured belt, with 100 mm faces (4 in) against plunging fire and sloped armor 50 mm (2 in). For ASW protection, the Bremen class incorporated twelve watertight compartments. Most were filled, used as coal bunkers. In addition there was a double bottom running for 56% of the total length of the hull.

This was significatly better than the Gazelle, which only protection was limited to an armoured deck ranging from 20 mm (0.79 in) to 25 mm (0.98 in) for the waterline slopes. At last, there was a conning tower, with walls 100 mm (3.9 in) thick, topped by a 20 mm (0.79 in) roof. The main guns received at some point shields 50 mm thick.

Propulsion


SMS Berlin diagram – Brasseys

The six cruisers propulsion system had two triple-expansion steam engines. A classic formula inherited from previous Gazelle class, each driving two screw propellers. SMS Lübeck, the fourth cruiser on seven differed completely in having two Parsons steam turbines, manufactured in UK, by Brown, Boveri & Company. They were mated on four screw propellers shafts. At the time, German manufacturing was still trying to produce reliable steam turbines.

However all seven ships had the very same boilers, ten coal-fired Marine-type water-tube models. This was two more than on the Gazelle, and they were truncated for this reasons into three funnels instead of two, the major giveaway for identification. These three funnels amidships were raked and heavenly spaced. SMS Bremen and Hamburg, the first two, differed from the pack in having three generators producing a total output of 111 kilowatts/110 volts. The rest were given two new smaller generators rated at 90 kilowatts for 110 volts.

The Bremen class triple-expansion engines were rated for 10,000 metric horsepower (9,900 ihp), to compare to just 6000 ihp (4500 Kw) on SMS Gazelle, and 8000 ihp (6000 Kw) for the other Gazelle class. This however did not traduced, contrary to what was expected, from previous cruisers: The Bremen class were expected to reach a top speed of 22 knots (41 km/h; 25 mph), Lübeck with her turbines (producing 11,343 metric horsepower or 11,188 shaft horsepower) reached 22.5 knots (41.7 km/h; 25.9 mph). The previous Gazelle class reached all 21.5 kts. Nevertheless the Bremen class ships exceeded these speeds on trials, beyond 22 knots.

For endurance, the Bremen class carried 860 tonnes of coal; This gave them an overall range of 4,270 nautical miles (7,910 km; 4,910 mi) at 12 knots. This was not better than the Gazelle class, reaching from 3,560 to 4,400 nmi (6,590 to 8,150 km) at the same speed. SMS Lübeck however had turbines, notoriously less efficient and her max radius of action was 3,800 nmi (7,000 km; 4,400 mi). With some improvements in internal accomodations allopwing to carry more coal, the last three, München, Leipzig and Dantzig reached however 4,690 nmi (8,690 km; 5,400 mi).

SMS Lübeck nevertheless was a breakthrough as being the first cruiser to test a steam turbine in the whole German navy and fastest of all warships in Germany on trials; Due to vibration issues and standardization, her four shafts were replaced by two during a modernization.

The small size of the cruisers meant armament was kept to a standard. Like the previous Gazelle class, the same ten 10.5 cm (4.1 in) SK L/40 guns. These trusted ordnance were placed by pairs all along the ships, one of each forward and stern deck, four in barbettes under hull recesses and two alongside the hull and behind, amidship. This was a 1,555 kgs (3,428 lb), 4.475 m (14 ft 8.2 in) long overall gun using a horizontal sliding-block breech design. It fired an AP or HE shell with a fixed Brass Casing, 105 millimetres (4.1 in) x 656 millimetres (25.8 in), the shell weighting 16–17.4 kilograms (35–38 lb) depending on the type, HE or AP respectively. Elevation was -10° to +30° and the Rate of fire 15 RPM. Muzzle velocity was 690 m/s (2,300 ft/s) and max range 12,200 metres (13,300 yd) at max elevation.


This armament, contrary to the earlier Gazelle class, was completed by ten 3.7 cm (1.5 in) Maxim guns. These were basically among the first “rapid-fire” or QF guns ever designed, meant to pummel approaching torpedo boats. They were basically scaled-up Vickers heavy machine guns (cal. 0.5 inches), already scaled-up version of the famous liquid-cooled 1890s machine guns created by Harold Maxim.

This ordnance was known in the Royal Navy as the QF 1 pdr Mark I (“pom-pom”), well exported. In Germany it was produced for both the Navy and Army and derived as an anti-aircraft gun, the Maxim Flak M14. It had a ~300 rpm (cyclic) rate of fire, a muzzle velocity of 1,800 ft/s (550 m/s) and a maximum firing range of 4,500 yards (4,110 m). On the Bremen class they were located all along the deck in single pintle mounts. In total, the Bremen class carried 150 rounds per guns, 1,500 total.

Late part of this armament, the Bremen class carried two 45 cm (17.7 in) torpedo tubes, with five torpedoes in reserve. They were submerged, on each broadside.

General assessment of the class


Agadir crisis (L’illustration newspaper), with Berlin in the background.

The Bremen class at large were seen at the time, like today, as quite an improvement over the Gazelle, being larger, roomier, faster, better armed and protected, they proved they could be something else that just glorified station gunboats for far away stations. The only disappointment came from SMS Lübeck, the first German steam turbine-drive cruiser in Germany. At the time, she was equipped by British Parsons turbines replicated in Germany, with many components provided by Krupp. The problem was it was a new tech to master and these equioments did not passed quality control, delaying much her entry into service. Worst still, SMS Lübeck lackluster sea trials (she ended as the slowest of the class, quite the opposite of what was expected) almost doomed the arguments of some young officers in the fleet to push towards this new technology. Also, SMS München pioneered another, vital system, wireless communication, helping to to its adoption in the German Navy. Indeed long range communication was found inadequate in several occasions, including as the July crisis ended with a state of war with ships caught in distant outposts. SMS München also served as target practice for U-1 and helped considerably the development and trust into the future U-Boat arm in the German Navy, far from being accepted back in 1905-1906.

For “colonial duties”, if its was the case for two, which indeed served all their peacetime years in the America and Asia stations, the rest served with various Scouting squadrons, basically screening units for the Hochseeflotte and played an active part in all the sorties of the fleet until Jutland. Some saw action in the latter, but due to adverse conditions, heavy weather or night, accuracy was poor and nothing definitive can be said on their battle performances, but for SMS Leipzig, which served in Asia most of her active years. Part of Von Spee’s famous squadron, she fought at Coronel, engaging HMS Glasgow twice, here and at the Falklands, where the latter chased her. Each time, despite her slower speed and weaker armament, she almost repelled the British cruiser, but was batterred and finished off by the larger armoured cruisers HMS Cornwall and Kent, still succeeding in hitting Cornwall eighteen times, firing her torpedoes. Its only when all her guns were silenced she was abandoned, and not striking the colors had terrible consequences, not lowering in any way the gallantry showed by her crew.

For those which stayed in home waters, post-Jutland years were pretty inactive: The front ate manpower, and the fleet failed to attract recruits enough, so as to be confronted to a sever shortage after the summer of 1916. So much so, that in several cases, the “old” Bremen-class were simply placed in reserve, left with a skeleton crew, much needed on more modern vessels. Only Hamburg and Berlin survived the treaty of Versailles, “granted” to the new interim navy, and then Reichsmarine of the interwar. Due to their age, they received limited upgrades and mostly served as training ships, bringing cadets, future officers of the Kriegsmarine, around the world.

Wartime service

SMS Bremen (1903)


SMS Bremen, Stettin and Moltke in Hampton Roads, 1912 (Lib. Congress)

SMS Bremen was ordered under contract name “L” at the AG Weser shipyard on 1 August 1902. Launched on 9 July 1903, christened by the city mayor, Dr. Pauli. She was towed afterwards to the Kaiserliche Werft for completion in Wilhelmshaven and commissioned for sea trials on 19 May 1904. Her first commanding officer was Korvettenkapitän Paul Schlieper. She reached 23.29 knots at this occasion, way better than specified, to the delight of the both the admiralty and yard, as she was the lead ship of her class. This made her one of the fastest cruiser at the time worldwide, and it was achieved using VTE engines. Trials ended successfully on 15 July and due to the policy of the time she was to be decommissioned. Instead she was sent to replace SMS Gazelle, the lead ship of the previous class, on the American Station. KK Richard Koch became her new captain from then on.

American Station service

After preparations for her deployment in Kiel, she left on 27 August, crossing the Atlantic while coaling en route to Funchal, Madeira, before reaching Rio de Janeiro on 25 September. She was soon placed under the authority of the American station’s flagship Cruiser Division SMS Vineta. The Venezuelan crisis in 1902–1903 opposed the latter to Britain, Germany, and Italy over economic issues, but was settled, so Bremen was detached instead on a cruise, showing the flag and protect German economic interests overseas, and bringing diplomatic muscle. The German division at the Danish port of Charlotte Amalie (Saint Thomas in the Carribean or Danish West Indies) became her main base.

She cruised with the gunboat SMS Panther until mid-April 1905, both anchored in Kingston, Jamaica, until the division was dissolved. SMS Bremen became the new local station ship and spent the rest of the year in training exercises with Panther. She later visited Newport News in Virginia until 23 May, making a short overhaul. She cruised in Central American waters, stopping at Veracruz, hosting members of the Mexican government.

In 1906, she made another short overhaul at Newport News until 14 May, then toured the east coast of South America, stopping at Bahía Blanca (Argentina), and on return, Port of Spain in Trinidad, then Kingston, where she received a distress call from the Hamburg America Line (HAPAG) as the SS Prinzessin Victoria Louise ran aground on a coral reef. She took off the passengers but failed to pull her free and the steamer was abandoned. In December 1906 Fregattenkapitän Hermann Alberts took command as she made another short overhaul in Newport News until April 1907.

Next, she joined the armored cruiser Roon to be present at the Jamestown Exposition commemorating (300th anniversary of the arrival of colonists in Chesapeake Bay), which took place on 26 April. Bremen toured harbors along the East Coast until back to her American station. In June 1907 she cruised north, into the Saint Lawrence River and stopped in Montreal, Canada, then along the Labrador. The crew’s conduit during the visits had Kaiser Wilhelm II sending a congratulation telegram.

SMS Bremen arrived in Port-au-Prince (Haiti) on 16 March 1908 to evacuate and protect threatened German nationals, whereas soon the Haitian government suppressed the revolt. She left with 57 Germans, heading to Kingston. She visited Philadelphia until 9 June, first ever German warship there, then New York, and back to South American waters. She assisted the Hamburg Süd (HSDG) steamer SS Cap Frio after running aground in Bahía Blanca, taking off passengers and crew. Next she was in Punta Arenas in Chile on 10 November, crossed the Strait of Magellan for the east coast. In November FK Albert Hopman was her new commander. After La Guaira, (Venezuela) by early 1909, her captain made a state visit to President Juan Vicente Gómez.

She was back in the Atlantic, making it Havana, Cuba, until mid-1909, helping supressing an harbor fire, then made a refit at Newport News until 15 May. After Haiti, Veracruz, she escorted SMS Victoria Louise, Hertha with the new Dresden at the Hudson–Fulton Celebration in New York.

300 German sailors took part in the international parade while FK Ernst Goette took command. They separated and depared on 14 October, Bremen sailing to Buenos Aires in December, meeting there the French armored cruisers Gueydon and Dupetit-Thouars.


SMS Bremen in NyC, 1909

By January 1910, Bremen was in Punta Arenas, and sailed to Tocopilla on 16 March, instructed to return to Argentina for the independence centennial, weathering a hurricane during the night of 29 April underway. There, she suffered an accidental explosion in her starboard side auxiliary engine room, but there was no fatality. She was in Buenos Aires on 10 May with Emden, staying until 15 June for repairs and a new cruiser along the coast of South America, ending in Callao (Peru), before being ordered back to Chile and be present at its own centennial Independence, held in Valparaiso until 3 October.

After a stop at Guayaquil (Ecuador), she wasn sent in Amapala (Honduras) to embark threatened foreigners, alongside British and US ships, also protecting civilians. They joined forces and sent an international landing party to defend their respective consulates, and the international quarter. Bremen departed on 13 November for Puerto San José (Guatemala), then Puntarenas (Costa Rica) conducting a survey of the harbor until 14 December, while the crew was on leave, some to visist German nationals. Captain Goette took part in the funeral of President Pedro Montt on 3 February 1911 and the cruiser was back in the Alantic on 28 February.


SMS Bremen off Hampton Roads, 1912

After a stop in Rio de Janeiro (19 March) she met SMS Von der Tann, for her shakedown cruise, before making an overhaul in Newport News, until 22 May. From Canadian waters in July, she was recalled to Haiti as a revolution just has broken out, sending landing parties in Port-au-Prince in August, leaving with nationals on board on 15 August. She made another overhaul in Newport News until 24 November, while Captain Hans Seebohm took command. In early 1912 she toured the Gulf of Mexico, and returned to the United States, later in April joining Moltke and Stettin off Cape Henry in Virginia, making the Detached Cruiser Division for an official visit, answering an USN visit in Kiel the previous summer. On 3 June they were in Hampton Roads for ceremonies and departed by mid-June.

SMS Bremen went through the Strait of Magellan, then back to Pernambuco in Brazil (20 December 1912), ordered this time to West Africa, supporting the gunboats Eber and Panther off Liberia. She left on 12 January 1913 via Freetown (Sierra Leone) and ordered to proceed back to Germany in late June (which was cancelled later). Back in Rio de Janeiro, she help putting down a fire onboard HSDG SS Etruska. She sailed newt to Saint Helena, Duala (German Cameroon), Freetown, Las Palmas (Canary) and by late September Funchal. She waitd for her replacement, SMS Karlsruhe, made ready to be replaced by Dresden.

This left her time to assist to the Mexican Revolution, protecting her nationals, with US Navy warships, on all cities along the east coast of Mexico. This ended in January 1914. She protected not only German, but also Austro-Hungarian, Dutch, French, and Spanish civilians, escorting SS Kronprinzessin Cecilie and SS Bolivia during the evacuation.

On 21 January, she was replaced as planned by SMS Dresden, but before returning home she steamed to Port-au-Prince for another protection missions of Germans there, relieving SMS Vineta. When the instability ceased the departed for Germany, after 9.5 years in the American station. She arrived in Bremen for a celebration held on 15 March 1914, then was moved to Wilhelmshaven to be decommissioned.

SMS Bremen in World War I

Contrary to her long American career, her wartime participation was short and brutal. She was sent in Kaiserliche Werft (Wilhelmshaven) for a full modernization, including four 10.5 cm for and aft replaced with two new 15 cm (5.9 in) SK L/45 guns in the axis. Her electrical system was modernized and improved, a new forward mast installed with a better spotting top. By July 1914 she was still in drydock, and this went on until 27 May 1915. Recommissioned, she completed her sea trials, being assigned to the Baltic Sea fleet.

From Kiel, she was in Libau in July, as part of the Reconnaissance Baltic Sea Command Sqn. (Konteradmiral Hopman). She was prepared for eastern Baltic operations, joining a sweep with the IV Battle Squadron north of Gotland. On 14 July, submarines both ambushed but missed her. Soon after, Kommodore Johannes von Karpf, visited Bremen on 30 July, and by early August 1915, she joined the push into the Gulf of Riga.

She was present at the Battle of the Gulf of Riga (8 August 1915), sailing from Libau to rescue the crew of the T52 after hitting a naval mine off Zerel, Ösel. She picked up survivors, transferred to SMS Braunschweig, then join the squadron entering the Gulf of Riga and on this 8 August, engaged in battle for the first time in her carreer, duelling with the Russian armored gunboat Khrabryi. On 16 August she was part in another push with Graudenz, Augsburg and Pillau, with Nassau and Posen in backup. They were shelled on arrival by the Russian pre-dreadnought Slava, but the latter withdrawn and by chasing her, penetrating minefields on 19 August in the Gulf. Bremen shelled Arensbur but had to withdraw due to the presence of British subs.

SMS Bremen was eventually ordered back to the North Sea, taking part in a sweep north of Gotland (September). On 30 September, Kommodore Hugo Langemak took command, as Bremen headed for the coast of Gotland (5-6 October) and conducted other sweeps into the northern Baltic. While on patrol with V191 and V186 (17 December) she met her fate, by entering a uncharted Russian minefield. V191 hit and sunk at 17:10, and while Bremen moved to rescue her, she struck two mines as well and sank quickly, her hull broken, carrying 250 men and leaving only 53 survivors, onboard a crowded V186, already with V191 survivors.

Hamburg (1903)


SMS Hamburg on Brassey’s naval annual 1905

SMS Hamburg was as “K” to AG Vulcan shipyard, Stettin, laid down in August 1902, launched 25 July 1903 and Christened by the First Mayor of Hamburg, Johann Heinrich Burchard. Then she was moved Kiel for fitting-out, and although not the first launched, she was the first of her class to enter service, commissioned on 8 March 1904. As defined in the naval law she was assignated from the start as the escort for the Imperial Yacht Hohenzollern. Delays in sea trials had her joining the Kaiser in June. She stayed with the Yacht for three months, from Kiel to Hamburg, where Wilhelm II embarked for a regatta in Norway from 7 July to 9 August and seeing the fleet maneuvers of late August-September.

Interwar service


HMS Hamburg and the Imperial Yacht Hohenzollern in Aandalsnaes, Norway, 1904.

From 28 September, Hamburg joined the Reconnaissance squadron, replacing the oldier SMS Niobe. This was followed by a winter training cruise in the Baltic Sea. A yearly cycle of peacetime routine commenced with summer fleet exercises and winter cruise, but in 1905 she was sent for another escort mission of the Hohenzollern, to Helgoland, Pillau and Glücksburg. She also cruised with with SMS Lübeck to compare their performances. In September 1906, Fregattenkapitän Oskar von Platen-Hallermund took command for a year, before being replaced by Korvettenkapitän Ernst Ritter von Mann und Edler von Tiechler.

In February 1908, SMS Hamburg started her training cruise into the Atlantic with the whole Reconnaissance squadron, going south in Vigo, Spain, but she was soon detached to escort Hohenzollern in March-May for a mediterranean cruise. They stopped in Venice, Corfu and back in mid-May to Germany. She later trained in the North Sea and with the High Seas Fleet in a large coordinated exercize. In 1908–1909, she was to be replaced by SMS Dresden, but the latter experienced turbines problems. By February 1909 she retunrned in Spain, Vigo, followed by another escort mission of the Kaiser’s yacht in another Mediterranean cruise with SMS Sleipner, to Venice and Corfu.

While in Corfu on 16 April, the Kaiser was reported Christian persecutions in the Ottoman Empire, which prompted reaction throughout Europe and ships were sent to the southern Anatolian peninsula, Hamburg detached as well on 21 April, first to Mersina, joined by HMS Swiftsure and Victor Hugo, Lübeck, before sending landing parties ashore together to protect civilians, distribute food and care. On 17 May, Hamburg was detached back home, stopping in Port Said and Málaga on her way back to Kiel.

Back to Germany, Hamburg was soon sent to escort Hohenzollern in company of SMS Gneisenau. They departed Kiel on 13 June for Neufahrwasser as Wilhelm II embarked aboard Hohenzollern, for a cruise in the northern Baltic to Finnish waters, for an official meeting of Tsar Nicholas II aboard his own yacht. She was back to Kiel on 20 June but returned with Hohenzollern for a sailing regatta in June-July, and celebrate a new German-Swedish passenger ferry line with Trelleborg, then another cruise on 18 July-3 August. She took place in annual fleet maneuvers for the first time in her career before being decommissioned in Wilhelmshaven, on 15 September, replaced in the scout squadron by Dresden.

SMS Hamburg spent 1910 and 1911 in reserve, while overhauled. Recommissioned on 2 July 1912 she became the second command flagship for I U-boat Flotilla (Torpedo-craft Inspectorate) from 6 August, and took part in training exercises in the North Sea, fleet maneuvers, and the routine went on until 1913, with KK Hermann Bauer appinted her new captain from November 1913, until March 1914, before the cruiser was versed to the U-boat Inspectorate.

SMS Hamburg in the great war

From July 1914, the Ist U-boat Flotilla was stationed at Helgoland, with Hamburg as command ship. On 6 August she teamed with SMS Stettin to escorted a U-boats into the North Sea, a sweep tp draw out the British fleet, as the cruisers acted as a bait for the U-boats arrayed behind in ambush. They failed and retuned home on 11 August, ad another on the 7th, until I and II U-boat Flotilla were dissolved and fusioned into a unew unit under the Führer der Unterseeboote, Hamburg as flagship.

She also sailed with IV Scouting Group during the raids on Scarborough, Hartlepool and Whitby on 15–16 December and at at 06:59 on the 16th Hamburg, Roon, and Stuttgart stumbled upon British destroyers (Loftus William Jones) which did not engaged but shadowed them until 07:40, when Hamburg and Stuttgart were detached at attack them. Admiral Friedrich von Ingenohl based n this decided to withdraw.

In 1915 she alternated between soties with the IV SG and her static U-boat flagship duties. On 21 April she collided with S21, sinking her while Hamburg experienced serious hull and bow damage, repairs before she sailed for another sortie on 17–18 May and 29–30 May, and a final one on 11–12 September, hosting II. Führer der Torpedoboote Kommodore Karl von Restorff and eventually on 23–24 October. None made contact with the enemy. In 1916 her unit sorties on 5–7, 25–26 March 21–22 and 24–25 April, and the raid on Yarmouth and Lowestoft.

SMS Hamburg was attached to the IV Scouting Group during the Battle of Jutland under command of Commodore Ludwig von Reuter. She departed on 31 May, and screened for the fleet with V73, assigned to the port side of the battle fleet, II Battle Squadron. They only made contact around 21:30, with the 3rd Light Cruiser Squadron but between long range and poor visibility, München and Stettin were the only one to engage them. Hamburg fired only one symbolic salvo in the haze. During the night engagements between cruisers and destroyers her unit reached Horns Reef by 04:00, on 1 June, but in hot pursuit with British cruisers and destroyers. Hamburg was hit several times as a result. While in the safety of Wilhelmshaven, battle damage was assessed. She had 14 killed and 25 wounded and repaired until 26 July.


SMS Hamburg Underway, 1915

The post-battle reports showed pre-dreadnoughts and older light cruisers like Hamburg were no longer for frontline operations. SMS Hamburg also never received modernization and both her fire control and limited wireless equipment were not fit to coordinate U-boats at sea. After he last sortie on 18–20 August she served as a headquarters ship in port, then barracks ship for U-boat crews, in Wilhelmshaven, with herself a sekeleton crew due to manpower shortage. From 15 March 1917 she was under command of Captain Friedrich Lützow and spent 1917 and 1918 in the same place, in total inaction. Hamburg was not interned in Scapa Flow, due to her age, and just remained in Wilhelmshaven during peace negotiations. The Führer der Torpedoboote and staff inspected her on February 1919 and it was decided later after the conclusion of the Versailles treaty she would be assigned to the Reichsmarinewerft in Wilhelmshaven, decommissioned on 16 August 1919.

SMS Hamburg interwar service (1920-1936)

Hamburg was left basically to rot during the very troubles years of 1919-21 in Germany. It appeared later she was authorized as part of the 12 cruisers allowed under the Versailles Treaty. She was recommissioned on 7 September (FK Bernhard Bobsien), assigned to Marinestation der Nordsee, flagship, Konteradmiral Friedrich Richter and then Kapitän zur See Walter Hildebrand in charge of the II, IV, and VI Flotillas tasked with clearing the minefields of the North Sea. KAdm Konrad Mommsen took command on 2 April 1921 and the cruiser went for her first interwar cruise, in the Shetland Islands (13-17 June).

In July 1921, SMS Hamburg took part in the first postwar fleet training exercises, with Hannover and Medusa, I and II Flotillas. She escorted minesweepers later as they cleared a minfield from Meteor. In Kola Bay however, they came under fire from a Soviet coastal battery and the Germans returned fire before withdrawing. This was one of the many hostile encounter and “quasi-war” with the Soviets in the Baltic at that time. After their mine-clearing operation, Hamburg toured Norwegian ports (Vardø, Hammerfest, Tromsø, Ålesund, Bergen) and back in Wilhelmshaven in August. In February 1922 she was used an auxiliary icebreaker to assist merchant vessels, but her hull was damaged and she was drydocked later for repairs. Braunschweig replacing her as the flagship Marinestation on 1 March 1922. She visited Odda in Norway and took part in the annual fleet maneuvers after which FK Erich Heyden became her new captain.

In July 1923, Hamburg visited Hanko in Finland, Rønne (Bornholm in Danish waters) but with unrest in Hamburg she was deployed there with two torpedo boats. She sent a landing party ashore to bolster the police efforts to restore order. From 15 October she was reassigned to one of the two Marinestation created while the fleet was reorganized. Hamburg became flagship (KzS Adolf Pfeiffer) light naval forces command, for the North Sea. 1924 was spent in peacetime routine between exercises and a cruise to Riga in July. Later, Hamburg had a new (famous future) captain: KAdm Erich Raeder -albeit briefly- then Kommodore Franz Wieting in January 1925.

She was based by then in Marinestation der Ostsee, Kiel. By May 1925 KzS Ernst Junkermann took command, followed by KzS Paul Wülfing von Ditten and KK Hermann Densch within months. She was transferred to the Training Inspectorate as training ship (FK Otto Groos) and prepared with special accomodation for a major training cruise circumnavigating the Earth, hosting the Mayor of her nameaske city, Carl Wilhelm Petersen which presented the city’s flag in 14 February 1926 ceremonies. From Cuxhaven, and downstream on the Elbe the cruiser reached the English Channel, the Atlantic, stopping at Pontevedra (Spain), Funchal (Portugal), and Las Palmas in the Canary Islands. From the central Atlantic, she crossed to the West Indies and passed through the Panama Canal and visited the west coast of North and Central America, cruising as far north as San Francisco, then the Pacific (Honolulu and Japan, the Philippines, and Manila, Iloilo City), then the Dutch East Indies, the Indian Ocean’s Colombo and British Ceylon, the Red Sea and crossing the Suez Canal, stopping in Vigo en route to Wilhelmshaven, her historic trip ending on 20 February 1927.

This was pretty much a way to end graciously as she was decommissioned on 30 June 1927, reduced to reserve, then stricken on 31 March 1931. In 1936 she was converted by the Kriegsmarine as a barracks ship for submarine crews (her old job) based in Kiel, remaining there until… 1944, when it was decided she was more useful as scrap metal and towed to Hamburg on 7 July 1944 but sunk by British bombers on 27 July and her remained scrapped after the war. Like Berlin, Hamburg bore a famous Germany city name and stayed in service for quite long. Rendition of the cruiser in 1926

Berlin (1903)


SMS Berlin in colonial livery (postcard) – white hull, canvas sand superstructure.

Prewar career

SMS Berlin was ordered as “Ersatz Zieten”, laid down at the Kaiserliche Werft, Danzig in 1902, launched 22 September 1903 (Chistened by the Mayor of Berlin, Martin Kirschner), completed in Kiel and commissioned for sea trials on 4 April 1905, lasting until 15 June, along with basic training. She was assigned as escort to the Imperial Yacht Hohenzollern for a cruiser starting on 18 June, from the Elbe river, Kiel Week, and Travemünde Week, followed by the annual summer cruise, visiting Gefle in Norway 12-16 July, and an official meeting with King Oscar II representing the Sweden–Norway alliance. Next, a Baltic Se cruise to Björkö, off the coast of Finland to meet Tsar Nicholas II on 23-24 July, then Copenhagen, to meet on 3 August King Christian IX and back to Kiel.

Assigned to the fleet, Berlin started exercizes and drills but no the annual manoeuvers, while Korvettenkapitän Hugo Kraft took command before she joined the Reconnaissance suqadron on 29 September 1905 replacing SMS Amazone, which crew was transferred to Berlin as she was decommisioned, replacing her initial trials crew. No doubt the latter, already experienced, saw the new criser as quite an upgrade. Berlin took part in intensive squadron training in the Baltic by November and fleet maneuvers in the North Sea. 1906-1907 with the same, with pushed to the Skagerrak, May-June fleet manoeuvers and summer cruises plus the annual large-scale fleet maneuvers in September. By October 1907, Fregattenkapitän Arthur Tapken took command.

The then commander of the High Seas Fleet, Admiral Prince Heinrich of Prussia asked to conduct four major training cruises into the Atlantic between 1908 and 1909 so twice yearly. This went down south to Vigo, Spain in February and July, but also Coruña and Horta in the Azores as well as Vilagarcía. SMS Berlin was also detached and assigned to the Imperial escort again, but this time Wilhelm II was aboard the fleet flagship pre-dreadnought SMS Deutschland, on a cruise to Helgoland and Bremerhaven 8-11 March 1908. Afterwards she was recalled to her unit and the training routine resumed, until in 1910, Admiral Henning von Holtzendorff replaced Heinrich as fleet commander, focusing on training exercises in the North and Baltic Seas instead of the not very useful and costly Atlantic cruises. In case of conflict indeed, the German Navy would likely clash with Britain (which announced the entente) as well as France. Until then, for a conflict with the French Navy only, Atlantic operations made sense to enforce a blockade, but the latter would have been difficult so close to British shores and in the channel. Berlin made a Norwegian waters summr cruise and had a new captain in September, KK Heinrich Löhlein.

1911 started like all previous years, with a cruise to Norway but in May, Berlin was in maintenance, joining the fleet for Baltic maneuvers and North Sea, but on 27 June, her captain received orders to redeploy to the coast of west Africa: This was the Agadir Crisis, and she was to replace the gunboat SMS Panther. She went through the Kaiser Wilhelm Canal and steamed through the Strait of Dover on 30 June–1 July, reaching Agadir in Morocco on the 4th of july. Panther stayed there too and on 20 July, Eber relieve her. Berlin and Eber made alternating trips to Las Palmas (Canary Islands) to recoal.

As a refresher, the Agadir crisis (also Second Moroccan Crisis or Panthersprung) was sparked by the deployment of French troops in the interior of Morocco in April 1911, which trigerred the deployment of a German gunboat there. Germany did not object to France’s expansion but wanted territorial compensation, that France refused, and to have more weight, dispatched SMS Berlin in reinforcement. despite the objections of German nationalists negotiations were larter held between Berlin and Paris, which resolved the crisis on 4 November 1911 as Morocco became a French protectorate and Germany obtained French Congo (now Rep. of congo, Gabon and centrafrica).

This was not a sound political move however for Germany as in Britain David Lloyd George (Chancellor of the Exchequer) made a dramatic “Mansion House” speech on 21 July 1911 denounced the German move and relations between Berlin and London worsened while Britain moved even closer to France. The deployment showed it was exceedingly difficult to communicate with Berlin, through the long-range Nauen Transmitter Station: French stations in the region indeed of course did not relay German signals and that was to be done by German merchant ships fitted with transmitters in the area instead.

By October 1911, SMS Berlin was recalled, and 3 November, FK Wilhelm Tägert took command while with SMS Eber she sailed back for Germany on 28 November, visiting underway Mogador, Casablanca, and Tangiers but crossed the path of a storm in the Bay of Biscay, damaging her, dlowing her down for repairs at sea during five days and a stop in Portsmouth to coal and complete repairs. She arrived in Kiel on 14 December. In 1912, she resumed her usual Reconnaissance Unit drills, fleet maneuvers of the North Sea and Baltic in summer plus annual fleet maneuvers. On 27 September 1912 she was reaffected to Wilhelmshaven to be decommissioned and replaced from 29 October. She stayed there until mid-1914 with a skeleton reserve crew.

Wartime Career

In July 1914, SMS Berlin was reactivated, a crew was mustered and she was recommissioned on 17 August, under command of FK Friedrich von Bülow. After short sea trials in July-August and training on 3-17 September, she was assigned as flotilla leader for the torpedo boat flotilla in Jade Bay, Bülow commanding both. On 17 September however she was reassigned to IV Scouting Group, replaced by the coastal defense ship Siegfried. IV Scouting Group was assembled for western Baltic training exercises in the idea she would be deployed later as a screening force for north sea operations. They were at the time affected to the Coastal Defense Division of the Baltic Sea, patrolling Langeland (Danish straits) in case of a possible attempt of a British raid, which never happened. On 3 October, IV SG was transferred to the German Bight, guarding the German North Sea coast until 24 October 1915.

While IV Scouting Group operated with the High Seas Fleet, Berlin was detached to the II Scouting Group, covering a minelaying operation off Swarte Bank on 17-18 April and off the Dogger Bank on 18 May 1914 when her sister ship SMS Danzig struck a mine, so Berlin took her under tow until a tugboat took over. SMS Berlin had an overhaul on 30 July-28 August, retrofitted with rails to carry 80 mines. She was afterwards detached from IV Scouting Group on 24 October, assigned to the Baltic Sea Naval Forces; First she headed for Kiel and sailed with Stuttgart and V Torpedo-boat Flotilla for Libau. She steamed to Windau area, replacing her sister ship SMS Bremen and towing Danzig struck by a mine to Neufahrwassar (25-26 November 1915).

By early 1916, the Germans started to disengage from the Baltic due to the pace and successes on land, and Berlin was transferred back to IV Scouting Group, leaving on 6 January 1916 with SMS Braunschweig and Mecklenburg escorted by X Torpedo-boat Flotilla to Kiel. She went through the Kaiser Wilhelm Canal and anchored in Wilhelmshaven, afterwhich she had a short overhaul before joining her unit on 3 February, resuming patrol duties in the German Bight. Her fleet sorties were on 3–4 and 25–26 March, as far as Amrun Bank, but for naught. On 18 May she was overhauled in dry-dock during the Battle of Jutland. She was out of the shipyard on 8 June and resumed patrols.

On 19 October while on patrol, SMS Berlin was ambushed by British submarine HMS E38, which launched, but missed, one torpedo however went further to hit SMS München, so SMS Berlon took her in tow back to port, relieved by a tugboat. In December 1916, SMS Berlin was transferred to II Scouting Group but on 14 January 1917 she was reassigned to coastal patrol duty, North Sea and by February sent to Kiel and Danzig for a decommission on 11 February due to her age and the need of her crew for more modern vessels. Disarmed, she was converted into a tender, commander of coastal defense forces (Baltic), a duty held from 26 April 1918 to the November.

Interwar career

SMS Berlin was one of the six light cruisers Germany was allowed to retain by virtue of Versailles treaty. She started as a training hulk for boiler room crews, then was sent to Kiel on 16 December 1919 for this, taking accomodations onboard, and having a new captain, Oberleutnant zur See Clamor von Trotha, until April 1921, then KL Hans Walther. Now into the Reichsmarine, the government decided to reactivate her as a cadet training ship.

She sailed to Wilhelmshaven, decommissioned on 10 June for a drydock overhaul and modernization, the most complete and well-planned of any other German cruiser of that time. She received a new clipper bow, new stern, a modified bridge, lighter aft mast, new radio and communication systems, eight modern 105mm/42 SK C/06 guns and two 500mm TT (New length 110.6m wl and 113.8m oa) – But still apparently the same old coal-burning powerplant. She was recommissioned on 2 July 1922, under command of KzS Wilfried von Loewenfeld (Naval Training Inspectorate). She sailed for her training cruise, with port calls in Scandinavia and the Netherlands. In 1923, she made a longer cruise to Norway, Iceland, and the Faroe Islands while in October 1923, KzS Paul Wülfing von Ditten too, command.

On 15 January 1924, Berlin made her first overseas cruise, the first by any German warship since the end of WW1. She went into the central Atlantic to Ponta Delgada in the Azores and Santa Cruz de Tenerife, Las Palmas (the Canary Islands), Funchal (Madeira) Cartagena (Spain) and back back in Kiel (18 March), followed by annual fleet maneuvers, hosting Otto Gessler, the Reichswehr’s minister. On 1st November she made another Atlantic cruise to as Central and South America, stopping en route to coal at Santa Cruz de Tenerife, Saint Thomas (U.S. Virgin Islands) and visited Cartagena (Colombia), Veracruz (Mexico) Havana, La Guaira (Venezuela), San Juan (Puerto Rico), and Ponta Delgada but she had back luck whent steamiong back through the Bay of Biscay, hit again by a severe storm. While in Kiel from 16 March 1925 she was repaired and KzS Ernst Junkermann took command that year in July.

She made another long range cruise on 9 September, reaching the western coast of South America, Ponta Delgada, Hamilton (Bermuda) Port au Prince (Haiti), Colón (Venezuela), Puerto Madryn (Argentina) Guayaquil (Ecuador), Callao (Peru) and in Chile, Valparaiso, Corral, Talcahuano, and Punta Arenas. While en route back north, she stopped in Mar del Plata, Buenos Aires, Montevideo, and Rio de Janeiro. Back east, she coaled in Vigo and made back to Kiel on 22 March 1926.

From 25 September, it was intended to replace her by the newly commissioned light cruiser KMS Emden, and her crew ws reduced; Under FK Hans Kolbe in command, she was transferred to Marinestation der Ostsee (Baltic Sea Naval Station), conducting a long-range cruise to the central Atlantic (April to June 1927) visiting the Azores, Portuguese and Spanish ports. In Horta (Spain) on 19 May, she assisted a stranded Portuguese sailing ship.

After fleet maneuvers she hosted President Paul von Hindenburg (14 September 1927) coming from KMS Schleswig-Holstein, and carried to Königsberg (East Prussia). KMS Hamburg was decommissioned so Berlin replaced her in the Naval Training Inspectorate, reassigned from 1 October. On 1st December she made her longest cruise ever: Fifteen months in all where she went in East Asia, visiting along the way Fremantle (Australia) and back to Cuxhaven on 7 March 1929, then moved to Kiel to be decommissioned on 27 March. She was in reserve until 1 October 1935 but the Kriegsmarine, under a new leadership had plans to rapidly expand the Navy and needed her for barrack ship purposes (and free her name for more modern vessels), so she was stricken and anchored in Kiel for the subsequent years and World War II. After 1945 she was loaded with nazi chemical weapons, scuttled in the Skaggerak on 31 May 1947. Her remains are still there today.

Lübeck (1904)


Potscard- SMS Lübeck

SMS Lübeck was ordered as Ersatz Mercur, laid down at AG Vulcan (Stettin) on 12 May 1903, launched on 26 March 1904, christened by the Bürgermeister of her namesake city. Fitting out dragged on, as she waited for the delivery of her turbines. It prevented to close the inner section of the hull, assembled and enclose the armored deck and complete alla above compartments. In all, eight months passed until 1 August 1904, the initial deadline set to Krupp, the components manufacturer of the turbin. The company had indeed significant problems casting the parts, all rejected due to quality issues.

Lübeck’s prewar service

SMS Lübeck finally started builder’s sea trials on 18 March 1905, commissioned for sea trials on 26 April. Fregattenkapitän Alexander Meurer was first in command. Sea trials immediately revealed turbines fell short of expecation and the ship never went close to the intended top speed. In fact, the turbines seemed to give no advantage over triple-expansion. These fed heated discussions over the utility of using turbines in cruisers. The Navy however still experimented with propeller arrangements, going as far as tryin eight screws on four shafts as it was seen on early topedo boats and destroyers. Different propeller sizes, blade pitches and shapes were also tried. In the end, Lübeck became the slowest of the whole class… but with a highest consumption.

On 30 October she was still under testings when the 1905 Russian Revolution prompted the Kaiser to send her, escorted by seven torpedo boats to Russia. He wated to evacuate his cousin, Tsar Nicholas II and his family if the situation degraded. So Lübeck patrolled in the Gulf of Finland before the crisis diffuse, so she returned to her sea trials. Only by March-April 1906 under Korvettenkapitän Hermann Nordmannand then KK Otto Philipp, she started operating as a flotilla leader, for the torpedo boat training flotilla. It went on until 25 April 1906, then with the School and Experimental Ships Unit until 17 May. Then Lübeck started a serie of competitive testing with VTE-equipped SMS Hamburg. On 27 August, her trials were at last concluded. Temporarily placed in reserve in Wilhelmshaven she awaited an assignation.

Reactivated on 22 September 1906 she joined the Reconnaissance Unit of the High Seas Fleet and for two years routinely trained and cruised in between fleet exercises. In October 1906, FK Felix Funke took command. Her 1907 fleet maneuvers were followed by a cruise to Skagen in Denmark and a mock attack on Kiel. After summer esercises in the North Sea, she cruised in Norway and took part in the annual autumn fleet maneuvers, delayed for a large fleet review in the Schillig roadstead for the Kaiser. She also trained with the IX Army Corp off Apenrade and her new captain became FK Ferdinand Thyen. By February 1908, she trained in the Baltic Sea and in summer around Helgoland, before a sweep into the Atlantic and major training cruise by decision of Prince Heinrich.

The latter were made difficult due to tensions with Britain over the Anglo-German naval arms race, starting on 17 July, from the Kaiser Wilhelm Canal to the North Sea, Atlantic and back to Germany on 13 August, followed by the autumn maneuvers until 12 September. In October she had a new captain, FK Robert Kühne and in 1908 toured coastal German cities. She acted as to increase public support for naval expenditures, wildly contested outside Prussia, notably in landlocked landers such as Bavaria and others. Never in its history Gezrmany had ever embarked on such a massive naval expansion, which was never traditional nor natural. The unpopularity of the fleet was notably predicted by naval thinkers such as Alfred Thayer Mahan. Even France, with its large naval exposition, tradition and extensive colonial Empire had a smaller fleet that Germany intended to built.

SMS Lübeck soon redeployed to the Mediterranean Sea on 19 April 1909. She reinforce the gunboat Loreley in Constantinople as serious unrest threatened Europeans residents and assets. Loreley was too small to effectively protect German interests by herself, notably her landing party was way too small. Lübeck patrolled the southern coast of Anatolia in June until recalled home reassigned to the Reconnaissance Unit. She participated in another cruise in the Atlantic this summer, and the Hochseeflotte, as a way to diffuse tensions and spy on the Germans, was invited Spithead, UK.

In May 1910 training maneuvers in the Kattegat were followed by a summer cruise in Norway, and fleet training then naval review off Danzig on 29 August, with Captain Hans Zenker taking command the newt year, in April 1911. This summer, the German fleet hosted a return goodwill visit of considerable magnitude: Both the British Grand Fleet and the American “great white fleet” were hosted at Kiel, for the now famous Kield week, punctuated with festivities and regattas. The autumn maneuvers took place in the Baltic and Kattegat, followed by a fleet review held for the Austro-Hungarian delegation, notably Archduke Franz Ferdinand, Admiral Rudolf Montecuccoli. Eventually, SMS Lübeck was decommissioned on 10 October 1911 with a skeleton crew.

Lübeck in the great war


SMS Lübeck underway, date unknown. From Journal of the United States Artillery, Volume 25 (1905)

By July 1914, SMS Lübeck was recommissioned and reactivated fully from 12 August, assigned to the Baltic Sea Coastal Defense Division, patrolling the Skagerrak area, the Little Belt and the Sassnitz-Trelleborg route off Sweden. By October 1914 she was sent to the eastern Baltic, taking part in a series of sweeps into the northern Baltic, the first on 8-13 October (off Bogskär), and on 24-31 October, then a raid on the Russian port of Libau (16–17 November) followed by two other sweeps in December, off Bogskär, Utö, Öland and Gotland.

March-April 1915 saw her engaged in support operations off Memel during the Russian counter-attack, shelling them from the shore. She even became flagship of Kommodore Johannes von Karpf to coordinate the Gorlice–Tarnów Offensive of May at the extreme left flank of the German Army. She spearheaded a diversionary attack on 27 April as stayed for the naval support with SMS Thetis shelling Libau during a landing demonstration, divert Russian attention as expected. Karpf left her for the cruiser Augsburg and in early May, the German still tried to seize Libau, and needed naval support Lübeck and several other cruisers provided on 6 May. She also patrolled the area in search of a possible Russian naval sweep.

Konteradmiral Albert Hopman took the head of the reconnaissance forces in the Baltic and ordered another assault on Libau covered by Lübeck, Augsburg and Thetis, but also Prinz Heinrich, Roon, and Prinz Adalbert, even the old Beowulf flanked by a massive escort of destroyers, torpedo boats, and minesweepers. The IV Scouting Group also joined in to provide additional cover and the bombardment proceeded. The destroyer V107 struck a mine close to the harbor and was lost but the Germans were overall successful and the the city fell. On 14 May, SMS Lübeck was detached to lay a minefield off the Gulf of Finland, with SMS Augsburg but as Russian submarines were spotted in the area, this sortie was cancelled.

During a patrol off Libau, on 28 June 1915, SMS Lübeck spotted and fired on a Russian destroyers squadron. Both sides soon folded up and withdrawn. On 1st July, the minelayer SMS Albatross sortied with Lübeck as an escort as well as Roon and Augsburg, to operate north of Bogskär and while back, Augsburg stayed with Albatross, heading for Rixhöft while the rest went to Libau. However Augsburg and Albatross fell on a powerful Russian squadron (Rear Admiral Mikhail Bakhirev), leading to the Battle of Åland Islands. Karpf ordered Albatross reach neutral Swedish waters, ordering Roon and Lübeck to her rescue. However Albatross was grounded en route off Gotland while Augsburg escaped. The Russian squadron evetually spotted Lübeck and Roon, few shots were exhanged but boths sides broke contact. Lübeck reported scoring eight hits on Rurik, but not hit in return. Hopman sortied with Prinz Heinrich and Prinz Adalbert in between, but too late, while the latter was torpedoed on route by British submarine E9.

Lübeck took also part later in the Battle of the Gulf of Riga from 8 August and on 9-10 August, she was ambushed and torpedoed by the Russian submarine Gepard off the Irben Strait (Gulf of Riga). Five torpedoes came from only 1,200 m (3,900 ft), but Lübeck’s spotters seen them and the captain ordered a hard rudder turn, evading them. Later she was attacked by a Russian aircraft off Windau on 10 September, not damaged. On 6 November 1915 she was also ambushed by British submarine E8, and again, dodged her torpedoes. She was back in Libau in January 1916.

The cruiser’s luck was about to run out. On 13 January, she struck a Russian mine. Her stern was lifted out of the water by the force of the blas, which also knocked down her mast, falling behind on the bridge, torn off and buckled as a result. Two killed, five wounded, 250 t of seawater flooding were the immediate result; She was however under escort and the torpedo boat V189 started towing her to safety, until the tugboat Weichsel took charge. She was carried to Neufahrwasser (close to Danzig) on 15 January, decommissioned on the 28th for provisional repairs, until she could be towed to AG Vulcan, Stettin, her constructor, for complete repairs. At this occasion she was modernized: She was fitted two of the new 15 cm (5.9 in) SK L/45 guns in place of her twin 105 mm foe and aft, and six 10.5 cm SK L/45 guns while the Maxim mounts were removed. This was completed by two 50 cm (19.7 in) torpedo tubes on deck and a new bow was provided, more modern, funnels were replaced by new models. She emerged in early 1917 as the most modern Bremen class cruiser.

however despite of this, crew shortages hit hard and many of her sister ships already has been decommissioned. As soon as she was out of drydock, she was placed in reserve until 15 March 1917, reactivated for use as a target ship, for the U-boat School, with a small service crew. Her new role only started on 11 February 1918. She notably trained the crews of the new massive U-cruisers just completed. Her sister ship ship SMS Stuttgart meanwhile just had been converted into a seaplane carrier, and Lübeck’s crew was chosen to man her. So she was formally decommissioned on 8 March. The Treaty of Versailles had her surrendered to the British as a war prize. She stricken in September 1919, formally ceded as “P”, but the British sold her for BU in 1922, dismantled in Germany in 1923.

München (1904)

sms Munchen date unknown
SMS Munchen underway, circa 1910

SMS München was ordered as “M”, laid down in AG Weser in Bremen, on 18 August 1903. Launched on 30 April 1904, she was christened by W.G. von Borscht, mayor of Munich, in a ceremony witnessed by Prince Ludwig III of Bavaria. Fitting-out was quick she she completed and started her initial sea trials by early November. After that she was installed her armament at Kaiserliche Werft, Wilhelmshaven, and underwent Navy acceptance trials, commissioned on 10 January 1905.

München peacetime routine of torpedo & wireless testings

SMS München made a shakedown cruise in the Baltic Sea until 30 March. She was used as a torpedo test ship replacing Nymphe and tested also wireless telegraphy. Following individual training exercises in April and May she had a new captain, Korvettenkapitän Friedrich Schultz before joining fleet training while still affected to the Training and Experimental Ships Unit. This summer, she trained at the western Baltic, off Swinemünde and notably firing tests to digest reports of the recent Russo-Japanese War.

In 1906 she went on on individual and unit exercises and changed captain in March, with KK Ferdinand Thyen. She was in Norwegian waters this summer, stopping at Bergen and Trondheim, sending wireless signals to the recently constructed Norddeich radio station to test long range transmissions. She did the same with Helgoland and Cuxhaven radio stations. KK Johannes von Karpf took command in October and a month later she trained with the old protected cruiser Vineta and the I Training Flotilla, in the eastern Baltic. On 9 December she was drydocked for periodic maintenance, until 25 January 1907.

The 1907, aside her same training pattern, she was visited by Kaiser Wilhelm II in June, seeing U-1 simulated attack against München, a first for the German Navy. After the the annual fleet maneuvers as flotilla leader for torpedo boats and a new captain in winter, KK Ferdinand Bertram she was overhauled in Kaiserliche Werft until 8 February 1908. That year she visited Trondheim, Bergen, and Stavanger in Norway and multiplied wireless experiments. After annual fleet maneuvers as leader of III Scouting Group, Reserve Fleet, Karpf returned to command and she left Kiel on 24 October for a test cruise off Vigo and Málaga, Funchal and Madeira, still testing radio. She was back in Kiel on 17 December. The routine repeated in 1909.

Her overhaul completed in February 1910 she had a new captain in March, KK Ernst-Oldwig von Natzmer and on 13 April during training she accidentally near-rammed the torpedo boat S122, passing in front of her München while trying to reach an attack position. However due the captain’s prompt reaction, her bow took the hull in an oblique angle, so she only had mushed steel and a damaged engine room (but two dead). Taken under tow, the TB was later repaired in Sassnitz.

München’s bow had no significant damaged and she resumed training until November, repaired and overhauled at the Kaiserliche Werft, Danzig. In 1911 she became a torpedo target ship at the Training and Experimental Ships Unit while KK Rudolf Bartels took command. She trained in Norwegian waters in July 1911, participated in a naval review on 5 September. She however lost six men during the the night of 26 October, when lowering a boat to moor the cruiser to a buoy, due to a front rope loosening. She went out of overhaul in January 1912, assigned to the III Scouting Group. This year again she test her wireless in Vigo.

This was the same in 1913, but during the annual fleet maneuvers she hosted Wilhelm II, Großadmiral Alfred von Tirpitz (State Secretary of the Imperial Naval Office), Admiral Friedrich von Ingenohl(fleet commander), and Admiral Georg Alexander von Müller (Chief of the Imperial Naval Cabinet). Off the Great Belt on 19 December she again lightly collided with a fast manoeuvering V159, but both only had minor damage. Her last peacetime overhaul was completed on 7 February 1914 and she keep her torpedo training and fleet maneuvers routine until the summer.

SMS München’s WWI operations

SMS München joined the III Scouting Group attached to the High Seas Fleet, planning to do some sweeps in the North Sea. Transferred to IV Scouting Group on 25 August she was foud with SMS Danzig transferred to the Baltic after the loss of SMS Magdeburg, to be soon back to the North Sea. She was moored at Brunsbüttel when the British Harwich Force attacked in the Helgoland Bight, leading to the Battle of Heligoland Bight, where München and Danzig were recalled, steam to the mouth of the Elbe to wait for orders, and ordrered to the Bay at 12:25, in support of SMS Strassburg. At 4:06, however München was detached to make a reconnaissance NW of Helgoland, but she spotted nothing and the battle ended.

Still with IV Scouting Group, Muenchen took part in the 3–4 November 1914 raid on Yarmouth avant-garde by I Scouting Group. She woukd take part also in the 15–16 December raid on Scarborough, Hartlepool and Whitby, as flagship of the II. Führer der Torpedoboote under command of a new captain, Karl von Restorff, but again, seeing no combat. München also took part in the 24 January 1915 raid in support of I Scouting Group seeing action of the 1st and 2nd Battlecruiser Squadrons at the Battle of Dogger Bank, but she arrived too late this afternoon to see action. She was also mobilized for the actions of 29–30 March and 18–22 April.

SMS Munchen at the Kieler week

On 7 May 1915 she was in the IV Scouting Group (München, Danzig, Stettin, Stuttgart, 21 torpedo boats) mobilized in the Baltic for a major German push against the strategic port of Libau, under command of Konteradmiral Albert Hopman. IV Scouting Group was to screen the main force to the north, to spot any Russian incursion from the Gulf of Finland. The Russians however intervened as feared, with the four cruisers Admiral Makarov, Bayan, Oleg, and Bogatyr, and spotted the IV SG, briefly engaging SMS München, but disengaged as they were unsure of their respective strength. The IV SG won a tactical victory. Libau was later captured, München being recalled west, to the High Seas Fleet.

She took part in several fleet sweeps, all failing to make contact with the enemy, on 17, 29–30 May, 11–12 September. München was in drydock maintenance (24 September to 31 October) and transferred to the Baltic on 18 January 1916, colliding during the night of her transfer with the freighter Moskau, off Rixhöft. Her port side was scraped, badly damaged and she returned in drydocked in Danzig, until 6 March 1915. Sge was sent back to the North Sea for another sortie on 25 March, off Amrum Bank, then on 24 April, covering the I Scouting Group on Yarmouth and Lowestoft.

At last in May 1916, she would see action, at Jutland: On 31 May with IV Scouting Group (Kommodore Ludwig von Reuter), she departed Wilhelmshaven in the early hours with the rest of the fleet, screening her flank, escorted herself by the torpedo boat S54 at her starboard side. The IV SG was abreast of the III Battle Squadron. The IV Scouting Group took up a position at the rear of the German line around 17:30 and weren’t heavily engaged this early in the battle. However much later that day, shortly after 21:00, their unit stumbled upon the British 3rd Light Cruiser Squadron (3rd LCS).

Their unit was leading the High Seas Fleet south when it happened, away from the Grand Fleet, and this was unexpected. But due to the obscurity and poor weather, only München and Stettin effectively saw and engaged the British cruisers: SMS München fired 63 shells without scoring any hits. She was hit twice: The first caused minimal damage, but the second struck her third funnel, causing damage to four of her boilers, so she slowed sown. Reuter made a turned hard to starboard but the 3rd LCS disengaged and this combat was over.

However the IV SG was not done with the battle of Jutland, and on 1st June, during the early hours, a ferocious night fighting developed, against specifically the British 2nd Light Cruiser Squadron, at close range and in the darkness. The Germans fired star shells that illuminated HMS Southampton and Dublin so focused their combined fire on these. Badly damaged and retreating, the unit fell back in an attempt to draw them closer to Moltke and Seydlitz. Frauenlob was hit and started sinking, and München nearly collided with her. Evading the wreck, she launched a torpedo at Southampton but missed. München was hit three times. Two near-misses causing minor splinter damage, but a shell landed in her second funnel, exploding on the funnel support, splinters knocking out her starboard rangefinder. The wheel shaft in the helm was bent, forcing to use the steering gear compartment for more than two hours, men forming a command chain for directions, from the bridge.

At 01:20, München and Stettin mistook the German torpedo boats G11, V1, and V3 for enemies and started fire before the latter fire a star shell specific to the German Navy. Around 05:06, the pre-dreadnought battleships of the II Battle Squadron also mistook both German cruisers for British submarines and near-missed both München and Stettin, steaming up alongside the German line. Fleet commander, Reinhard Scheer soon ordered a general cease-fire to avoid more confusion. München spotted an imaginary submarine off Heligoland later at 11:40 and opened fire. When the paranoia of battle ceased, a damage report was done. München was hit five times, killing eight men, wounding twenty (sources differs in this), while firing 161 rounds. She needed repairs afterwards to her engine room and funnels, at Vegesack and Wilhelmshaven on 7-30 July.

She took part in another sweep on 18–19 August off the Dogger Bank. Again on 18–19 October, Scheer attempted a raid on Sunderland, which happened to be SMS München’s final wartime operation. She was ambushed en route by HMS E38 off the Dogger Bank. The latter launched a sprey of torpedoes, one hitting the cruiser. While Scheer cancelled the operation and returned, München took 500 metric tons of seawater flooding, loosing her boilers and contaminating the freshwater circuit used for steam. She was towed back to port by V73, and SMS Berlin. After provisional repairs, she steamed into the Jade Bight and entered the Kaiserliche Werft for possible repairs. However a commissioned examined her, determined it was better due to her age to decommission her in November 1916. Disarmed, she ended as barracks ship for patrol ships in 1918. Stricken on 5 November 1919, she became war prize “Q” on 6 July 1920, the British sinking her as a torpedo target in the Firth of Forth, on 28 October 1921.

Leipzig (1905)

SMS Leipzig was ordered as “N” at AG Weser shipyard (Bremen), laid down on 12 July 1904, launched on 21 March 1905 and fitting out in February 1906, started her builder’s trials. She was armed in Wilhelmshaven to and commissioned on 20 April 1906, making her official sea trials until mid-June 1905 with Fregattenkapitän Franz von Hipper (yes, that one) on command. She also escorted Kaiser Wilhelm II onboard cruise aboard the HAPAG steamer Hamburg for his annual summer cruise.

Peacetime career with the East Asia Squadron

Next, she was assigned to the East Asia Squadron, her crew preparing on 19 August, sailing from Wilhelmshaven on 8 September and went via the Med, Suez canal, Indian Ocean and arrived through the Dutch East Indies, to Hong Kong on 6 January 1907. She joined the protected cruiser Hansa and until 10 March, stayed as guard ship at Tsingtao, Kiautschou Bay. She visited the Yangtze river with Vizeadmiral Carl von Coerper on board and escorted by the gunboat Tiger and torpedo boat S90. In June 1907 she toured with the rest of the squadron northern ports in the region and made another in 1908, in northern East Asian waters followed by a trip in the Yellow Sea thus summer, before greeting her new captain, Richard Engel. In September-October, she visited Shanghai and another voyage in the Yangtze. On 17 November she flew her national flag at the Kobe naval review in Japan, before KK Karl Heuser took command, and was later dry-docked at Hong Kong for maintenance in January 1909.

She was ordered to German Samoa as unrest against German rule was ripe and colonial governor, Wilhelm Solf, requested assistance. For the first time she stopped en route to Manila in the Philippines and later arrived in Apia, capital of German Samoa on 19 March. She was soon joined by SMS Arcona and the gunboat Jaguar, plus the troopship Titania with 100 local police onboard. The local chief were captured and exiled. The ships patrolled off Samoa and in May departed. Leipzig took back Vice Admiral Coerper to Suva (Fiji) on 14-17 May, transferred to another vessel to sail back to Germany while Leipzig returned to Samoa, replaced later by SMS Condor, then steamed to Pago Pago (American Samoa), back to Apia, and headed for Tsingtao, via Pohnpei and Manila, arriving on 29 June. She later trained with the squadron (flagship armored cruiser Scharnhorst).

In early 1910, Leipzig, Scharnhorst and the gunboat Luchs in Hong Kong, cruised in southern waters, visiting Siam and various South China Sea ports like Shanghai and Formosa. FK Hermann Schröder became her new commander and they made a voyage back north via Japan in April-May. Leipzig cruised the Yangtze in July 1910, as far as Hankou to quell unrest. With SMS Gneisenau she went to Calcutta next, in early 1911 meeting Crown Prince Wilhelm touring East Asia, arriving on on 31 January. In March Konteradmiral Günther von Krosigk took command of the squadron and visited Leipzig for his first visit to Japan, meeting there the Emperor Meiji.

Leipzig visited other destinations in Japan and Siberia, and while off Vladimir Bay in mid-August 1910, Captain Schröder learned about tensions with France over Agadir, but the Russians being allied with the latter, they severed telegraph lines and the cruiser only received a garbled wireless message indicating the squadron was to be redeployed to the Indian Ocean. Leipzig wasn sent to Vladivostok, and remained there for confirmation on 15-18 August, exchanging telegraphs with Germany, learning the crisis had passed. The squadron was in the Yellow Sea and made it back to Tsingtao on 15 September.

On 10 October, the 1911 Revolution broke out in China and unrest threatened foreign interests. This prompted Krosigk to deployed the east asia squadron to protect German nationals. Leipzig sent a landing party to reinforce thos from the gunboats Tiger and Vaterland, while Gneisenau was in Nanking, the gunboat Iltis in Hankou. Japanese Rear Admiral Kawashima Reijirō took command of the international forces, combined efforts of various landing parties ashore, evacuating women and children to Shanghai. Leipzig (Krosigk’s flasghip) left Hankou in November due to the low tide in the Yangtze, joining Gneisenau in Shanghai, spending several months patrolling between Tsingtao and trouble ports along the coast, until early August 1912. Next she returned to her training cruise routine, to Vladivostok and Japan, present for the funeral ceremonies of the last Emperor Meiji.

She also was sent in Shanghai and visited cities of central Chinese coast, until in March 1913, her new captain, Johann-Siegfried Haun took command, her final one as was was already looming. The cruiser stayed as an observer as civil war went awhol, with imperial and republican forces clashing around Nanking this summer. She was back to Tsingtao in September, overhauled until October. She sailed south and visited the Philippines, then by May 1914, she relieved the light cruiser Nürnberg by then stationed off the Pacific coast of Mexico, protecting German interests during the Mexican Revolution. She was posted off Mazatlán, on 7 July 1914 together with Dresden and Nürnberg, and the three cruisers sent landing parties to evacuate foreigners. Due to cutout telegraph lines they never learnt of the July Crisis in Europe, and only received news of the war on 31 July. Oddly, just nearby at a few nautical miles, French and Brithsh vessels were also anchored, providing help to their own civilians. Leipzig transferred forty refugees to the then neutral US armored cruiser USS California, then preparations for wartime operations.

Leipzig coaling off Mexico, Sept. 08, 1914

Leipzig was still Magdalena Bay in Mexico, awaiting orders when they came on 5 August, Captain Haun informing the crew of the state of war between Germany and the Triple Entente, and opened secret instructions in case of war, informing of the gathering of all ships of the East Asia Squadron. Leipzig needed coaling and stopped in San Francisco, but she was unable to fully replenish her bunkers due to US neutrality laws. Haun decided to start a commerce raiding campaign to get his coal from captured allied merchant vessels. Finding none, Haun returned in the Gulf of California on 17 August to get coal, and later sank her first British freighter, carrying sugar underway to the Peruvian coast. She coaled in Guaymas, Mexico, coaling fully on 8 September and on the 10 proceeded south with Naval HQ instructions to stop in the Galápagos Islands where a German merchant vessel was stationed, but but reports of a British squadron there led the ship to diverge course.

After stopping to clean her boiler tubes, burning bad coal until then, she resumed her voyage to Easter Island, arriving on 14 October, joining the rest of the East Asia Squadron under command of Vice Admiral Maximilian von Spee. Leipzig had had gathered three colliers for next operations and departed on 18 October with the rest of the Squadron, heading for South America, stopping in the Juan Fernández Islands and Mas a Fuera, then Valparaiso in Chile, receiving fresh intel about the British cruiser HMS Glasgow present in Coronel. Spee decised to ambush the British ship there, ingoring the presence of the HMS Good Hope and HMS Monmouth, both armoured cruisers.

Leipzig therefore participated in the Battle of Coronel: Leipzig stopped a Chilean barque while off Coronel, searched her and let her go. Leipzig took the head of the squadron. Later on 1 November, she spotted a column of smoke, and later identified three unknown ships, which were Cradock’s squadron. The British in turn spotted Leipzig and both squadron formed into lines of battle. Leipzig was then ordered as the third ship in line, behind the two armored cruisers for protection. At 18:07, each ship was ordered to engage its opposite number and fire broke at 18:34.

This meant Leipzig duelled with HMS Glasgow, but without success due to the range. At 18:49, HMS Glasgow, a recent Town class cruiser was heavier, faster and better armed with two 6-in guns and ten secondaries, and hit Leipzig. The shell however was a dud. Leipzig and Dresden afterwards both targeted Glasgow, hit five times. Spee afterwards ordered Leipzig to close and finish off Good Hope -savaged by the Schanrhost and Gneisenau- with a torpedo, but her approach was marred by a rain squall, and she discovered the ship had already sunk. By 20:00, Leipzig met Dresden in the darkness, which nearly fired on each other, and proceeded back to the Squadron. For this first battle, Leipzig remained essentially unscathed, with not even a wounded crewmen.

Spee afterwards to head for Valparaiso and wait orders. Scharnhorst, Gneisenau, and Nürnberg proceeded into the harbor while Leipzig and Dresden escorted the colliers to Mas a Fuera. The rest of East Asia Squadron at east arrived on 6 November and allcruisers resupplied. On 10 November, Leipzig and Dresden went to Valparaiso in turn and after resupplying, joined the Squadron stationed 250 nautical miles west of Robinson Crusoe Island. They coaled in the Gulf of Penas on 21 November and prepared to to cross the difficult Cape Horn. The British outrage after their defeat of coronel prompting to detach two battlecruisers (HMS Invincible and HMS Inflexible) from their grand fleet, under command of Vice Admiral Sturdee, and clear orders to “search and destroy” Spee’s squadron. Departing on 11 November they were in the Falklands on 7 December, together with the battleship Carnarvon, and the cruisers Kent, Cornwall, Bristol and Glasgow, just repaired.

HMS Glasgow

On 26 November, the East Asia Squadron departed Penas and crossed the Cape Horn on 2 December. Leipzig captured the Canadian Drummuir, carrying 2,750 t of coal, transferred to the colliers Baden and Santa Isabel, stationed at Picton Island. On 6 December, Spee held a conference with all his commanders to decide to attack the Falklands, ingoring the presence of the powerful British fleet here. Haun, opposed the plan and proposed to bypassing the Falklands and rampage merchant traffic off La Plata. Spee’s seniority prevailed however, and set the Falklands on 8 December as primary orbjective, a fateful decision.

When approaching Port Stanley, they were spotted, the British ships raising steam, take by Spee as the British were burning their coal stocks. Later he realized there was a powerful British squadron, and decided to broke off and flee, the British in hot pursuit. By 12:55, the battlecruisers, faster, caught up and opened fire on Leipzig, last ship in the German line. Spee at 13:15bravely decided to cover the retreat of hos light cruisers, turning to face the British, five minutes later. Sturdee sent his fast cruisers to chase down Nürnberg, Dresden, and Leipzig however, and the battle developed between the two Scharnhorst and the two Invincible, which turned badly for Hipper.

Glasgow chased off Leipzig, her old adversary, and caught up. She opened fire by 14:40 and fired during 20 minutes, hitting Leipzig mutiple times until the latter turned to port to open the range, then starboard to present a full broadside. Both ships pummeled themselves hard, Glasgow eventually breaking off, falling behind the armored cruisers. However Leipzig was now battered by Cornwall and Kent. Soon she was on fire, but went on firing. She hit Cornwall eighteen times and three torpedoes (which failed). At 19:20 however, Leipiz had no guns operational left, all has been knowcked out, her funnels and mast broken, and fires obscured her vision. Haun issued order to scuttle and abandon ship. The British approached nevertheless, opened fire at close range, making a bloody mess on the bridge while crewmen were just trying to evacuate. This did not not stop there as they also engaged even a cutter filled with survivors, destroying it. No quarter was given and no rescue was attempted, but 18 men eventually were later saved from these freezing waters.

Danzig (1905)

SMS Danzig was ordered as “Ersatz Alexandrine” at the Kaiserliche Werft, Danzig laid down on 12 July 1904, launched on 23 September 1905 (christened by namesake’s Bürgermeister Heinrich Otto Ehlers), followed by fitting-out work, builders trials, armament, official trials with commission on 1 December 1907. Trials ended on 6 April 1908 after which she was assigned the light cruiser Arcona’s crew, assigned to I Scouting Group. Her first voyage was into the central Atlantic this summer, with the battleship squadrons as wanted by Prince Heinrich to break the monotony of German waters training, amidst tensions with Britain. All were back on 13 August, followed by autumn maneuvers (27 August-12 September), Danzig earning the Kaiser’s Schießpreis or Shooting Prize for accuracy excellence in the I Scouting Group. Therefore in 1910, she was used as training ship for the fleet’s gunners.

By August 1914 she was in Brunsbüttel with SMS München, and sailed to Kiel via the Kaiser Wilhelm Canal on the 28th when the British attacked the Heligoland Bight. Both cruisers during the ensuing battle were ordered to steam to the mouth of the Elbe, and proceed to the side, Leipzig arriving where Ariadne just sank, lowering boats to rescue survivors. Konteradmiral Franz von Hipper ordered his cruisers to regroup his cruisers towards the battlecruisers Von der Tann and Moltke, but Fregattenkapitän Reiß refused, to stay and continue the rescue, as for Munchen.

On 7 May 1915, the IV Scouting Group (with Danzig, München, Stettin, and Stuttgart) were ordered to the Baltic, supporting the offensive on Libau under Rear Admiral Hopman. The IV Scouting Group was deployed in a screen to spot and engage a possible Russian naval force from the Gulf of Finland. However when Admiral Makarov, Bayan, Oleg, and Bogatyr arrived and spotted the Germans, the fire exchange was bref until both forces broke off.

Libau was soon captured ans the IV Scouting Group was recalled. On 8 May 1915, Danzig joined the IV Battle Squadron en route to a sweep off Gotland until 10 May. Danzig however ran into a Russian minefield on 25 November 1915, hit one and was towed back to port to be repaired.

SMS Lepizig during Operation Albion, in cover of the attack on ösel Island

In early September 1917, after the fall of Riga, an operation was planned against the last Russian strongholds in the Gulf. The Navy High Command planned Operation Albion to seize Ösel island, and the gun batteries threatening passage in the Sworbe Peninsula. On 18 September, the joint operation with the army commenced with flagship Moltke leading the the III and IV Battle Squadrons, Danzig being assigned to the II Scouting Group, screening for the invasion force, under command of Prince Adalbert, Kaiser Wilhelm II’s son. On the 19th with Königsberg and Nürnberg she tried to intercept two Russian torpedo boats but could not locate them and broke off.

This was her last significant operation. Outside the routine of training, the cruiser was sidelined due to her age, freeing her crew for other, more modern cruisers, and eventually after inactivity for the remainder of 1915 and 1916, she was withdrawn from active service in late 1917, but only stricken on 5 November 1919. She became British war prize “R’ on 15 September 1920, but the latter decided to have her broken up in Whitby in 1921–1922.
