SMSSeydlitz[a] was abattlecruiser of the GermanKaiserliche Marine (Imperial Navy), built inHamburg. She was ordered in 1910 andcommissioned in May 1913, the fourth battlecruiser built for theHigh Seas Fleet. Named afterFriedrich Wilhelm von Seydlitz,Seydlitz represented the culmination of the first generation of German battlecruisers, which had started with theVon der Tann in 1906 and continued with the pair ofMoltke-class battlecruisers ordered in 1907 and 1908.Seydlitz featured several incremental improvements over the preceding designs, including a redesigned propulsion system and an improved armor layout. The ship was also significantly larger than her predecessors—at 24,988 metric tons (24,593 long tons; 27,545 short tons), she was approximately 3,000 metric tons heavier than theMoltke-class ships.
Seydlitz participated in many of the large fleet actions duringWorld War I, including the battles ofDogger Bank andJutland in theNorth Sea. The ship suffered severe damage during both engagements; during the Battle of Dogger Bank, a 13.5 in (34.3 cm) shell from the British battlecruiserLion struckSeydlitz's rearmost turret and nearly caused amagazine explosion that could have destroyed the ship. At the Battle of Jutland she was hit twenty-one times by large-caliber shells, one of which penetrated the working chamber of the aftsuperfiring turret. Although the resulting fire destroyed the turret, the safety measures imposed after the battle of Dogger Bank prevented a catastrophe. The ship was also hit by a torpedo during the battle, causing her to take in over 5,300 metric tons of water and herfreeboard was reduced to 2.5 m. She had to be lightened significantly to permit her crossing of theJade Bar. The ship inflicted severe damage on her British opponents as well; early in the battle, salvos from bothSeydlitz and the battlecruiserDerfflinger destroyed the battlecruiserQueen Mary in seconds.
Seydlitz saw limited action in theBaltic Sea, when she provided screening for the German flotilla that atBattle of the Gulf of Riga attempted to clear the gulf in 1915. As with the rest of the German battlecruisers that survived the war, the ship was interned inScapa Flow in 1918. The ship, along with the rest of the High Seas Fleet, wasscuttled in June 1919, to prevent her seizure by the BritishRoyal Navy. She wasraised on 2 November 1928 and scrapped by 1930 inRosyth.
In early 1909, discussions began among the leadership of the GermanKaiserliche Marine (Imperial Navy) over the nextbattlecruiser to be built, which would follow the twoMoltke-class battlecruisers that were then still under construction. By that time, clear design philosophies had emerged in the two navies that were building battlecruisers: the BritishRoyal Navy preferred heavily armed, but lightly armored, ships, while the Germans favored heavily armored, but somewhat more lightly armed vessels.Korvettenkapitän (Corvette Captain)Waldemar Vollerthun, then the head of the navy's General Department, wrote a memorandum in March 1909 that succinctly explained the difference as "the 'English Battleship-Cruisers' stand against our 'Cruiser-Battleships'."[1] Vollerthun argued in the memorandum that the twoMoltke-class ships would need to complete theirsea trials before design work on the next ship—provisionally titled "J"[b]—could begin. Furthermore, he stated that developments indreadnought battleship design indicated that the caliber of themain battery should be increased from 28 to 30.5 cm (11 to 12 in) (though he conceded that the former gun was still sufficient against foreigncapital ships). He also recommended lowering the armordeck to save weight.[1]
The navy's Construction Department issued its own memo on the same day as Vollerthun's document. They disagreed with lowering the armor deck, but suggested the adoption of triplegun turrets for the main battery (instead of the twin turrets used in previous vessels). The Weapons Department rejected the latter proposal. An initial conference was held on 4 April to discuss parameters for the new ship. The Budget Section informed the participants that no increase in cost could be permitted overMoltke. The project saw no further work until 13 August, when the Construction Department reminded the other departments that deadlines were approaching if the navy wanted work to begin in 1910. On 28 August, the departments were informed that an additional 750,000 marks would be made available by a public fundraising effort; this money could be used to make improvements over theMoltke design. AdmiralAlfred von Tirpitz, the head of theReichsmarineamt (Imperial Navy Office) requested a preliminary design be made available by 27 September, so he could present it toKaiser Wilhelm II for consideration. Tirpitz's criteria were as follows: armament would remain the same asMoltke (ten 28 cm guns);displacement and length should only moderately increase from the earlier ship.[3]
The naval engineerHans Bürkner submitted a pair of proposals on 23 September. The first, "I", was an improvement overMoltke, but with increased armor protection and a slightly longerhull to offset the greater displacement of about 700metric tons (690long tons; 770short tons) and maintain the same maximum speed. The second, "II", had the same armor improvements as "I" but with the armor deck lowered as Vollerthun had suggested to keep displacement within limits, though it had increased by 1,000 t (980 long tons; 1,100 short tons) compared toMoltke. A third option, "III", reverted to the four-turret arrangement ofVon der Tann but increased the caliber to 30.5 cm; three subvariants were included with slightly different armor arrangements. Two days later, the Construction Department provided the proposals to Tirpitz, who postponed a final decision; he was still unsure of whether ordering a third member of theMoltke class was preferable, since it could be built faster than a new design. In the meantime, the Construction Department produced a revised design, "IIb" on 8 October; a slight increase in displacement bought improved internal subdivision of the propulsion machinery spaces.[4]
After a conference with the Kaiser atRominten, Tirpitz agreed that "IIb" should be adopted, but offered an increase in displacement from 24,000 to 24,700 t (23,600 to 24,300 long tons; 26,500 to 27,200 short tons) for additional improvements, primarily an increase in armor for the propulsion machinery spaces. Though the debate appeared to be settled, the Construction and General Departments then submitted a fourth design, "IVe", which significantly revised the layout of the main battery; one of thewing turrets was moved forward to asuperfiring position over the fore turret, and the other wing mount was moved to thecenterline. This arrangement provided increased firepower forward and maintained the samebroadside. Bürkner wrote a memorandum on 13 December comparing "IIc" and "IVe"; in addition to the improvements in offensive power, it was structurally superior. The General Department issued its own evaluation on 20 December, which concluded that "IVe" was preferable, even if it had somewhat worse internal subdivision. The following day, Tirpitz convened a meeting to discuss the designs. The need to proceed quickly to take advantage of a favorable negotiating position withBlohm & Voss led those present to decide in favor of "IIc". On 7 January 1910, settled on a slightly improved version, "IIe", which raised theforecastle and made a few minor increases to the armor layout. The Kaiser approved the proposal on 27 January.[4]
Seydlitz was 200 meters (656 ft 2 in) long at thewaterline, and 200.6 m (658 ft 2 in) overall. The ship had a beam of 28.5 m (93 ft 6 in), which was increased to 28.8 m (94 ft 6 in) with anti-torpedo nets equipped. She had a draft of 9.29 m (30 ft 6 in) forward and 9.09 m (29 ft 10 in) aft.Seydlitz displaced 24,988 metric tons (24,593 long tons) as designed, which increased to 28,550 t (28,100 long tons) atfull load.Seydlitz had adouble bottom for 76 percent of the length of the hull. Her hull was divided into seventeenwatertight compartments. The entire structure consisted ofSiemens-Martinmild steel. All internal decks were fitted withlinoleum, while the external decks were layered withteak planking.[5][6]
The ship had a raised forecastle deck that extended for the first third of the ship's length, where it stepped down to the upper deck, which in turn covered the central third of the ship. Further aft, a reducedquarterdeck stepped down atmain deck level. Hersuperstructure consisted primarily of a largeconning tower forward, located directly aft of the fore turret. It had a smallerbridge erected atop it. A smaller, secondary conning tower was located further aft.Seydlitz was fitted with a pair of polemasts, which could be used tosignal nearby vessels or transmitwireless signals. The masts were also equipped withcrow's nests for spotting purposes.[6]
The ship carried a number of smaller boats, including onepicket boat, three barges, twolaunches, twoyawls, and twodinghies.Seydlitz was described as having been a goodsea boat with gentle motion. The ship lost up to 60 percent of her speed at a hard rudder, and would heel over to 9 degrees.Bilge keels were fitted to reduce any tendency to roll and thereby improve stability. The ship had a standard complement of 43 officers and 1025 men, and when serving as the flagship ofI Scouting Group, this increased by an additional 13 officers and 62 men.[6][7]
Seydlitz was propelled by four Parsons direct-drivesteam turbines, which were manufactured under license by Blohm & Voss. The turbines were arranged in two sets. Each set consisted of a high-pressure outboard turbine which exhausted into a low-pressure inboard turbine. Each turbine drove a 3-bladedscrew propeller that was 3.88 m (12.7 ft) in diameter. They were placed in their own individualengine rooms, the high-pressure turbines further forward of the low-pressure engines. Steam for the turbines was provided by twenty-seven small-tubeThornycroft-Schulz boilers that had two fire boxes per boiler. The boilers were divided into fiveboiler rooms, and the aft-most three were partitioned by an internal longitudinal bulkhead. The boilers were ducted into a pair of widely spacedfunnels. Electrical power was provided by six turbogenerators that produced 1,800 kW at 220 V.[7][8]
The engines were designed to produce 63,000metric horsepower (62,000 shp) and a top speed of 26.5knots (49.1 km/h; 30.5 mph). Usingforced draft on trials, the engines provided up to 89,738 metric horsepower (88,510 shp) and a top speed of 28.1 knots (52.0 km/h; 32.3 mph). The ship carried up to 3,600 tonnes (3,500 long tons) of coal. In 1916, supplemental oil firing was added to improve the burn rate of the coal. With full fuel stores,Seydlitz could steam at a cruising speed of 14 knots (26 km/h; 16 mph) for 4,200nautical miles (7,800 km; 4,800 mi). At 26.75 knots (49.54 km/h; 30.78 mph), the ship was calculated to have a cruising radius of 1,605 nmi (2,972 km; 1,847 mi). The ship experienced some vibration when steaming at 21 knots (39 km/h; 24 mph) and while steaming astern, but it was not significant enough to disrupt the aiming of the guns. Steering was controlled by a pair ofrudders that were arranged on the centerline.[5][9]
Seydlitz mounted a nearly identical main battery to that of the precedingMoltke-class ships: ten28 cm (11 in) SK L/50 guns[c] in five twin-gun turrets. The guns were arranged similarly as well, with one turret fore, two staggered wing turretsamidships, and two super-firing turrets aft.[7] They were placed in newer C/1910 mountings,[11] which enabled depression of the guns down to −8 degrees and elevation to 13.5 degrees—the same range of motion of the earlier C/1908 turrets. At 13.5 degrees, the guns could be fired to 18,100 m (59,400 ft). In 1916,Seydlitz had her main turrets modified to allow for elevation up to 16 degrees, for a maximum range of 19,100 m (62,700 ft). Each turret was equipped with a 3 m (9.8 ft)rangefinder, apart from the rear turret, and an additional 3 m rangefinder was fitted in the gunnery control tower, which was located directly aft of the conning tower. The main battery was supplied with 87 armor-piercing rounds per gun, for a total of 870 shells.[7] In addition to the 305-kilogram (672 lb) shell, each gun chambered a 24.0 kg (52.9 lb) forepropellant charge in a silk bag and a 75.0 kg (165.3 lb) main charge in a brass case. The guns fired the shells at amuzzle velocity of 880 m/s (2,900 ft/s). The guns were hand-rammed, which required the barrels to be returned to 0 degrees elevation for reloading. Training and elevation was controlled hydraulically.[12]
Seydlitz carried a similarsecondary battery to the precedingMoltke-class design. She mounted twelve15 cm (5.9 in) SK L/45 guns in singlecasemates along the center of the ship. These guns firedarmor-piercing shells at arate of 4 to 5 per minute. The guns could depress to −7 degrees and elevate to 20 degrees, for a maximum range of 13,500 m (14,800 yd), and after the 1916 refit, the range was extended to 16,800 m (18,400 yd). The shells weighed 51-kilogram (112 lb) and were fired at a muzzle velocity of 735 m/s (2,410 ft/s). The guns were manually elevated and trained.[7][13][14]
For defense againsttorpedo boats, the ship was also armed with twelve8.8 cm (3.5 in) SK L/45 quick-firing guns, which were mounted in casemates as well. Four were located in the forecastle; two were in the forward superstructure; another pair were placed in the aft superstructure; and the remaining four were located in the aft upper deck, near the rear superfiring turret.[15] These guns fired 7.04 kg (15.5 lb) at a muzzle velocity of 590 mps (1,936 fps). Their rate of fire was approximately 15 shells per minute; the guns could engage targets out to 6,890 m (7,530 yd). The gun mounts were manually operated.[13][16] Two of these guns were removed in 1916 and replaced with high-angle 8.8 cm Flak L/45anti-aircraft guns.[7] The rest of the 8.8 cm guns were slowly removed over the course of the next two years, and their casemates were welded closed.[15]
As was customary for all German capital ships of the time,Seydlitz was equipped with four submergedtorpedo tubes. The ship mounted one tube in the bow, one in the stern, and one was on each side of the vessel. The weapons were 50 cm (19.7 in) in diameter, and a total of eleventorpedoes were stored. She was initially equipped with the G6 version, which carried a 140 kg (310 lb) warhead and could be set at two speeds for different ranges. At 27 knots (50 km/h; 31 mph), the torpedoes could reach 5,000 m (16,000 ft) and at 35 knots (65 km/h; 40 mph), the range fell to 2,200 m (7,200 ft). These were replaced beginning in 1913 by the G7 type, which carried a 200 kg (440 lb) warhead. Their range increased significantly, to 17,200 m (56,400 ft) at 27 knots and 7,400 m (24,300 ft) at 37 knots (69 km/h; 43 mph).[7][17]
Seydlitz's armor consisted ofKruppcemented and nickel steel. Her side armor was divided into three components: astrake that extended for the full length of the hull, which comprised thebelt armor. Above that, another strake that began at frame 32.5 (just aft of the rearmost main battery turret) and extended to frame 130 (just forward of the fore turret) was referred to as the citadel. Lastly, a third strake above the citadel covered the secondary battery casemates, extending for the length of the secondary battery. The main belt was 300 mm (11.8 in) thick for the length of the citadel, tapering down to 200 mm (7.9 in) at the top edge and 150 mm (5.9 in) at the bottom. Further aft, it reduced to 100 mm (3.9 in). The bow section of the belt tapered from 120 mm (4.7 in) down to 100 mm at thestem, and it too decreased to 80 mm (3.1 in) at the upper edge. The citadel strake was 265 mm (10.4 in) thick, and both ends were capped with transverse bulkheads that ranged in thickness from 220 to 230 mm (8.7 to 9.1 in). Krupp steel that was 150 mm (5.9 in) thick protected the casemate battery.[18]
A curved armor deck covered the entire hull; the central, flat portion was 1.4 m (4 ft 7 in) above the waterline, while the sloped sides extended down at an angle of 30 degrees to connect to the bottom of the belt armor. Inside the citadel, the flat deck and sloped sides were 30 mm (1.2 in) thick. Forward of the citadel, the flat and sides of the deck were a uniform 50 mm, while the stern section of the deck was 50 mm on the flat and 30 mm on the sides. Atop the casemate, another 25 mm upper deck provided additional protection. Extending down from the sloped deck were a pair of longitudinal bulkheads; the outertorpedo bulkhead was 50 mm thick.[19][20]
The forward conning tower had 300 mm of armor on the sides, and a 130 mm (5.1 in) thick roof. A communication shaft protected with 200 mm extended down from the conning tower. Her aft conning tower received 200 mm on the sides and 50 mm on the roof, and its communication shaft received 150 mm above the deck and 80 mm below. The turrets were protected by 250 mm (9.8 in) on the faces and 200 mm on the sides; their roofs were 100 mm on the sloped forward edge, reduced to 70 mm (2.8 in) on the flat portion. The supportingbarbettes were protected by plating 230 mm thick; below the main barbette, a smaller shaft that was armored with 30 mm thick steel extended down to themagazines.Seydlitz's secondary guns were fitted with 80 mm thickgun shields, while most of the 8.8 cm guns were equipped with 50 mm shields, with the exception of the forward set that were not fitted with shields.[18]
Thekeel forSeydlitzlaid down on 4 February 1911 at the Blohm & Voss shipyard inHamburg; she was named after thePrussian cavalry generalFriedrich Wilhelm von Seydlitz. She waslaunched on 30 March 1912, and was christened byGeneral der KavallerieKarl Wilhelm Heinrich von Kleist. A shipyard crew took the ship toKiel in April 1913, conducting acceptance testing on the way. There on 22 May, the ship wascommissioned into the German fleet, her crew being taken from the oldarmored cruiserYorck, which had been recently transferred to thereserve fleet. Her first commander wasKapitän zur See (KzS—Captain at Sea) Moritz von Egidy.Seydlitz then began sea trials, which were interrupted from 29 June to 3 July. In late June,Seydlitz was ordered to join the Kaiser at theKiel Week sailing regatta, though the voyage was used to calculate fuel consumption. While there, the ship received a visit from the Kaiser on 29 June and KingVictor Emmanuel III of Italy on 3 July.[21][22]
While still on trials on 26 July, the ship brieflyran aground offFriedrichsort in heavy fog. The ship's initial testing was completed on 17 August, and she soon thereafter joined the rest of theHigh Seas Fleet off the island ofHelgoland on 31 August for the annual fleet exercises, which concluded on 9 September.Seydlitz was assigned to I Scouting Group and participated in all routine training activities of the unit through mid-1914. These included large-scale unit maneuvers in March 1914 in theNorth Sea, and then exercises with the rest of the fleet in the North andBaltic Seas in April and May. In June,Seydlitz again sailed to visit Kiel Week. On 23 June, the vessel became theflagship ofKonteradmiral (Rear Admiral)Franz von Hipper, the commander of I Scouting Group. Further fleet exercises were carried out initially in theSkaggerak, beginning on 13 July.Seydlitz led the group during the fleet's short cruise to Norwegian waters later in July, which was cut short by theJuly Crisis that led to the outbreak ofWorld War I at the end of the month.[21][23]
Seydlitz and the rest of the fleet receivedmobilization orders on 1 August, indicating war was imminent.[24] Beginning on 4 August, I Scouting Group was tasked with guarding theGerman Bight;Seydlitz and the other battlecruisers provided cover to lighter forces that patrolled the area for enemy warships. Shortly after the outbreak of World War I, a brief engagement between German light cruisers and a raiding force of British cruisers and battlecruisers took place on 28 August 1914. During the morning, British cruisers from theHarwich Force attacked the German destroyers patrolling the Heligoland Bight. Six German light cruisers—Cöln,Strassburg,Stettin,Frauenlob,Stralsund, andAriadne—responded to the attack and inflicted serious damage to the British raiders. The arrival at approximately 13:37 of the British 1st Battlecruiser Squadron, under the command of Vice AdmiralDavid Beatty, quickly put the German ships at a disadvantage.[25][26]
Along with the rest of the I Scouting Group battlecruisers,Seydlitz was stationed in theWilhelmshaven Roads on the morning of the battle. By 08:50, Hipper had requested permission from AdmiralFriedrich von Ingenohl, the commander in chief of the High Seas Fleet, to send his ships to relieve the beleaguered German cruisers.[27] The battlecruisersVon der Tann andMoltke were ready to sail by 12:10, but the lowtide prevented the ships from being able to pass over thesand bar at the mouth of theJade Estuary safely. At 14:10,Moltke andVon der Tann were able to cross the Jade bar; Hipper ordered the German light cruisers to fall back to his ships, while Hipper himself was about an hour behind inSeydlitz. At 14:25, the remaining light cruisers—Strassburg,Stettin,Frauenlob,Stralsund, andAriadne—rendezvoused with the battlecruisers.[28]Seydlitz arrived on the scene by 15:10, whileAriadne succumbed to battle damage and sank. Hipper ventured forth cautiously to search for the two missing light cruisers,Mainz andCöln, which had already sunk. By 16:00, the German flotilla turned around to return to the Jade Estuary, arriving at approximately 20:23.[29]
On 2 November 1914,Seydlitz, followed byMoltke,Von der Tann, and the armored cruiserBlücher, along with fourlight cruisers, left the Jade Estuary and steamed towards the English coast.[30] The flotilla arrived offGreat Yarmouth at daybreak the following morning and bombarded the port, while the light cruiserStralsund laid a minefield. The British submarineD5 responded to the bombardment, but struck one of themines laid byStralsund and sank. Shortly thereafter, Hipper ordered his ships to turn back to German waters. While Hipper's ships were returning to German waters, a heavy fog covered the Heligoland Bight, so the ships were ordered to halt until visibility improved so they could safely navigate the defensive minefields. The armored cruiserYorck made a navigational error that led the ship into one of the German minefields.Yorck struck two mines and quickly sank; the coastal defense shipHagen was able to save 127 men of the crew.[30]
I Scouting Group next went to sea on 20 November to cover the transfer of the brand-new battlecruiserDerfflinger to Wilhelmshaven.Seydlitz and the rest of the unit, accompanied byStrassburg,Stralsund, and V Torpedo-boat Flotilla, sailed about 80 nmi (150 km; 92 mi) to the north of Helgoland before turning back for port. They encountered no British forces during the sortie.Derfflinger thereafter joined I Scouting Group.[31]Seydlitz and the rest of the group sailed again on 9 December in a short sweep into the German Bight, which ended without result.[32]
Ingenohl decided that another raid on the English coast should be carried out in the hopes of luring a portion of theGrand Fleet into combat where it could be destroyed.[30] At 03:20 on 15 December,Seydlitz,Moltke,Von der Tann,Derfflinger, andBlücher, along with the light cruisersKolberg,Strassburg,Stralsund, andGraudenz, and two squadrons of torpedo boats left the Jade.[33] The ships sailed north past the island of Heligoland, until they reached the Horns Reef lighthouse, at which point the ships turned west towards Scarborough. Twelve hours after Hipper left the Jade, the High Seas Fleet, consisting of 14dreadnoughts and 8pre-dreadnoughts and a screening force of 2 armored cruisers, 7 light cruisers, and 54 torpedo boats, departed to provide distant cover.[33]
On 26 August 1914, the German light cruiserMagdeburg had run aground in theGulf of Finland; the wreck was captured by the Russian navy, which found code books used by the German navy, along with navigational charts for the North Sea. These documents were then passed on to the Royal Navy.Room 40 began decrypting German signals, and on 14 December, intercepted messages relating to the plan to bombard Scarborough.[33] The exact details of the plan were unknown, and it was assumed that the High Seas Fleet would remain safely in port, as in the previous bombardment. Beatty's four battlecruisers, supported by the 3rd Cruiser Squadron and the1st Light Cruiser Squadron, along with the2nd Battle Squadron's six dreadnoughts, were to ambush Hipper's battlecruisers.[34]
During the night of 15 December, the main body of the High Seas Fleet encountered British destroyers. Fearing the prospect of a nighttime torpedo attack, Ingenohl ordered the ships to retreat.[34] Hipper was unaware of Ingenohl's reversal, and so he continued with the bombardment. Upon reaching the British coast, Hipper's battlecruisers split into two groups.Seydlitz,Moltke, andBlücher went north to shell Hartlepool, whileVon der Tann andDerfflinger went south to shell Scarborough and Whitby.[35] During the bombardment of Hartlepool,Seydlitz was hit three times andBlücher was hit six times by the coastal battery.Seydlitz suffered only minimal damage, and no casualties.[35] By 09:45 on the 16th, the two groups had reassembled, and they began to retreat eastward.[36]
By this time, Beatty's battlecruisers were in position to block Hipper's chosen egress route, while other forces were en route to complete the encirclement. At 12:25, the light cruisers of II Scouting Group began to pass through the British forces searching for Hipper.[37] One of the cruisers in the2nd Light Cruiser Squadron spottedStralsund and signaled a report to Beatty. At 12:30, Beatty turned his battlecruisers towards the German ships. Beatty presumed that the German cruisers were the advance screen for Hipper's ships, but the battlecruisers were some 50 km (27 nmi) ahead.[37] The 2nd Light Cruiser Squadron, which had been screening for Beatty's ships, detached to pursue the German cruisers, but a misinterpreted signal from the British battlecruisers sent them back to their screening positions.[d] This confusion allowed the German light cruisers to escape and alerted Hipper to the location of the British battlecruisers. The German battlecruisers wheeled to the northeast of the British forces and made good their escape.[37]
Both the British and the Germans were disappointed that they failed to effectively engage their opponents. Ingenohl's reputation suffered greatly as a result of his timidity. The captain ofMoltke was furious; he stated that Ingenohl had turned back "because he was afraid of eleven British destroyers which could have been eliminated ... under the present leadership we will accomplish nothing."[38] The official German history criticized Ingenohl for failing to use his light forces to determine the size of the British fleet, stating: "He decided on a measure which not only seriously jeopardized his advance forces off the English coast but also deprived the German Fleet of a signal and certain victory."[38]

In early January 1915, it became known that British ships were conducting reconnaissance in theDogger Bank area. Ingenohl was initially reluctant to attempt to destroy these forces, because I Scouting Group was temporarily weakened whileVon der Tann was in drydock for periodic maintenance.KonteradmiralRichard Eckermann, the Chief of Staff of the High Seas Fleet, insisted on the operation, and so Ingenohl relented and ordered Hipper to take his battlecruisers to the Dogger Bank.[39] On 23 January, Hipper sortied, withSeydlitz in the lead, followed byMoltke,Derfflinger, andBlücher, along with the light cruisersGraudenz,Rostock,Stralsund, andKolberg and 19 torpedo boats from V Flotilla and II and XVIII Half-Flotillas.Graudenz andStralsund were assigned to the forward screen, whileKolberg andRostock were assigned to the starboard and port, respectively. Each light cruiser had a half-flotilla of torpedo boats attached.[39]
Again, interception and decryption of German wireless signals played an important role. Although they were unaware of the exact plans, the cryptographers of Room 40 were able to deduce that Hipper would be conducting an operation in the Dogger Bank area.[39] To counter it, Beatty's1st Battlecruiser Squadron, Rear Admiral Archibald Moore's2nd Battlecruiser Squadron and CommodoreWilliam Goodenough's 2nd Light Cruiser Squadron were to rendezvous with CommodoreReginald Tyrwhitt's Harwich Force at 8:00 on 24 January, approximately 30 nmi (56 km) north of the Dogger Bank.[39] At 08:14,Kolberg spotted the light cruiserAurora and several destroyers from the Harwich Force.[40]Aurora challengedKolberg with a search light, at which pointKolberg attackedAurora and scored two hits.Aurora returned fire and scored two hits onKolberg in retaliation. Hipper immediately turned his battlecruisers towards the gunfire, when, almost simultaneously,Stralsund spotted a large amount of smoke to the northwest of her position. This was identified as a number of large British warships steaming towards Hipper's ships.[40]
Hipper turned south to flee, but was limited to 23 knots (43 km/h), which was the maximum speed of the older armored cruiserBlücher. The pursuing British battlecruisers were steaming at 27 knots (50 km/h), and quickly caught up to the German ships. At 09:52,Lion opened fire onBlücher from a range of approximately 20,000 yards (18,000 m); shortly thereafter,Queen Mary andTiger began firing as well.[40] At 10:09, the British guns made their first hit onBlücher. Two minutes later, the German ships began returning fire, primarily concentrating onLion, from a range of 18,000 yards (16,000 m). At 10:28,Lion was struck on the waterline, which tore a hole in the side of the ship and flooded a coal bunker.[41] At 10:30,New Zealand, the fourth ship in Beatty's line, came within range ofBlücher and opened fire. By 10:35, the range had closed to 17,500 yards (16,000 m), at which point the entire German line was within the effective range of the British ships. Beatty ordered his battlecruisers to engage their German counterparts.[e] Confusion aboardTiger led the captain to believe he was to fire onSeydlitz, which leftMoltke able to fire without distraction.[41]
Seydlitz was struck in her forecastle at 10:25, by a 13.5 in (343 mm) shell fromLion, but this hit did minor damage. At 10:40,Lion hitSeydlitz with another 13.5 in shell, which holed the deck and penetrated the rear barbette. The shell itself failed to enter the barbette, but the explosion flashed into the working chamber and detonated the propellant charges inside.[42]
In the reloading chamber, where the shell penetrated, part of the charge in readiness for loading was set on fire. The flames rose high up into the turret and down into the ammunition chamber, and thence through a connecting door, usually kept shut, through which men from the ammunition chamber tried to escape into the fore turret. The flames thus made their way through to the other ammunition chamber and thence up to the second turret, and from this cause the entire guns' crews of both turrets perished very quickly. The flames rose above the turrets as high as a house.[41]
The explosion killed 159 men, and destroyed both of the rear turrets. The fire was prevented from spreading to the shell magazines, which could have destroyed the ship, by the quick action of the executive officer, who ordered both magazines be flooded.[f] ThePumpenmeisterWilhelm Heidkamp was severely injured when he turned the red-hot valves to flood the magazines.[44] At 11:01,Seydlitz struck back atLion, and with a single 28 cm shell, knocked out two ofLion's engines. Shortly thereafter, a pair of 30.5 cm shells fired byDerfflinger struckLion, one at the waterline. The penetration allowed water to enter the port feed tank—this hit eventually crippledLion, the sea water contamination forced the ship's crew to shut down the port engine.[43] At 11:25,Seydlitz was struck on her armored belt amidships by a third and final shell, which did little damage.[42]
By this time,Blücher was severely damaged after having been pounded by heavy shells. The chase ended when there were several reports of U-boats ahead of the British ships; Beatty quickly ordered evasive maneuvers, which allowed the German ships to increase the distance to their pursuers.[45] At this time,Lion's last operational dynamo failed, which dropped her speed to 15 knots (28 km/h). Beatty, in the strickenLion, ordered the remaining battlecruisers to "Engage the enemy's rear," but signal confusion caused the ships to solely targetBlücher, allowingMoltke,Seydlitz, andDerfflinger to escape.[46] By the time Beatty regained control over his ships, after having boardedPrincess Royal, the German ships had increased their lead to a distance too great for the British to reengage; at 13:50, he broke off the chase.[47]Seydlitz was repaired at theKaiserliche Werft (Imperial Shipyard) in Wilhelmshaven from 25 January to 31 March 1915, after which she rejoined the fleet.[42] The ship participated in a series of uneventful sweeps into the North Sea over the following months, on 17–18 and 21–22 April and then 17–18 and 29–30 May.[48]
On 3 August 1915,Seydlitz,Moltke, andVon der Tann were transferred to the Baltic with I Scouting Group to participate in a planned foray into theRiga Gulf. The intention was to destroy the Russian naval forces in the area, including the pre-dreadnoughtSlava, and to use the minelayerDeutschland to block the entrance to Moon Sound with naval mines. The German forces, under the command of Hipper, included the fourNassau and fourHelgoland-class battleships, the battlecruisersSeydlitz,Moltke, andVon der Tann, and a number of smaller craft.[49] Throughout the operation,Seydlitz and the other two battlecruisers remained in the Baltic and provided cover for the assault into the Gulf of Riga. They were to prevent any Russian naval reinforcements from interfering in the operation.[50]
On 10 August, the battlecruisers spotted a Russian armored cruiser in the distance, which proved to beBayan.Von der Tann briefly engaged the cruiser, but beforeSeydlitz joined the action, a German torpedo boat signaled a submarine sighting, which caused the Germans to abruptly break off the engagement. The next morning, the ships arrived offDanzig to replenish coal. I Scouting Group was again off station on 16 August; over the following days, the Germans repeatedly spotted submarines in the area. Early on 19 August, one of these submarines hitMoltke with a torpedo, which prompted Hipper to take his ships back to Danzig to evaluate the damage to the ship. That vessel was sent for repairs, whileSeydlitz andVon der Tann returned to operations off the Gulf of Riga. The two battlecruisers and their escorts operated in the area on 21 August, but departed later that evening for Kiel.[51]
Following the operation,Seydlitz and the other heavy units of the High Seas Fleet returned to the North Sea. On 11–12 September,Seydlitz and the rest of I Scouting Group covered a minefield laying operation offTerschelling. Another sweep into the North Sea took place on 23–24 October in the direction ofEsbjerg, which again ended without encountering enemy forces. On 24 November, the ship ran aground in theKaiser Wilhelm Canal, but was quickly refloated. On 4 December, while exiting the Kaiser Wilhelm Canal,Seydlitz became entangled in one of the net barriers. Divers had to remove the tangled nets from the starboard screws.Seydlitz was present on 3–4 March 1916 for the first major operation conductedVizeadmiral (Vice Admiral)Reinhard Scheer, the new commander of the High Seas Fleet.[44][48]
On 24–25 April 1916, I Scouting Group undertook another operation to bombard the English coast, this time, the towns of Yarmouth and Lowestoft. Hipper was on sick leave, so the German ships were under the command ofKonteradmiralFriedrich Boedicker, who flew his flag inSeydlitz. The German battlecruisersDerfflinger,Lützow,Moltke,Seydlitz andVon der Tann left the Jade Estuary at 10:55 on 24 April, and were supported by a screening force of 6 light cruisers and two torpedo boat flotillas.[52] The heavy units of the High Seas Fleet sailed at 13:40, with the objective to provide distant support for Boedicker's ships. The British Admiralty was made aware of the German sortie through the interception of Germanwireless signals, and deployed the Grand Fleet at 15:50.[52]
By 14:00, Boedicker's ships had reached a position offNorderney, at which point he turned his ships northward to avoid the Dutch observers on the island of Terschelling. At 15:38,Seydlitz struck a mine, which tore a 15 m (50-foot) hole in her hull, just abaft of the starboard broadside torpedo tube. Eleven men were killed and 1,400 short tons (1,200 long tons) of water entered the ship. The ship's draft increased 1.4 metres (4.6 ft) at the bow of the ship.[52]Seydlitz turned back with the screen of light cruisers at a speed of 15 knots (28 km/h). The four remaining battlecruisers turned south immediately in the direction of Norderney to avoid further mine damage. By 16:00,Seydlitz was clear of imminent danger, so the ship stopped to allow Boedicker to disembark. The torpedo boatV28 brought Boedicker toLützow, and the operation continued as planned. After Boedicker departed the ship,Seydlitz, escorted by a pair of torpedo boats, withdrew southward to the Jade.[53] She was out of service for over a month for repair work due to the mine damage.[54]
Almost immediately after the Lowestoft raid, Scheer began planning another foray into the North Sea. He had initially intended to launch the operation in mid-May, but the mine damage toSeydlitz had proved difficult to repair—Scheer was unwilling to embark on a major raid without his battlecruiser forces at full strength. On 22 May, the Wilhelmshaven dockyard reported the ship to be fit for duty, but tests carried out that night showed that the broadside torpedo flat that had been damaged by the mine was still not watertight, and there were still leaks in the fore and aft transverse bulkheads. Further repairs were necessary, and so the operation was postponed another week, by which time the Wilhelmshaven dockyard assured Scheer that the ship would be ready. At noon on 28 May, the repairs toSeydlitz were finally completed, and the ship returned to I Scouting Group.[55]
On the night of 30 May 1916,Seydlitz and the other four battlecruisers of I Scouting Group lay in anchor in the Jaderoadstead. The following morning, at 02:00 CET,[g] the ships slowly steamed out towards theSkagerrak at a speed of 16 knots (30 km/h). By this time, Hipper had transferred his flag fromSeydlitz to the newer battlecruiserLützow.Seydlitz took her place in the center of the line, to the rear ofDerfflinger and ahead ofMoltke. II Scouting Group, consisting of the light cruisersFrankfurt, Boedicker's flagship,Wiesbaden,Pillau, andElbing, and 30 torpedo boats of II, VI, and IX Flotillas, accompanied Hipper's battlecruisers.[56]
An hour and a half later, the High Seas Fleet under the command of Scheer left the Jade; the force was composed of 16 dreadnoughts. The High Seas Fleet was accompanied by IV Scouting Group, composed of the light cruisersStettin,München,Hamburg,Frauenlob, andStuttgart, and 31 torpedo boats of I, III, V, and VII Flotillas, led by the light cruiserRostock. The six pre-dreadnoughts ofII Battle Squadron had departed from the Elbe roads at 02:45, and rendezvoused with the battle fleet at 5:00.[56]
Shortly before 16:00, Hipper's force encountered Beatty's battlecruiser squadron. The German ships were the first to open fire, at a range of approximately 15,000 yards (14,000 m).[57] The British rangefinders had misread the range to their German targets, and so the first salvos fired by the British ships fell a mile past the German battlecruisers. As the two lines of battlecruisers deployed to engage each other,Seydlitz began to duel with her opposite in the British line,Queen Mary. By 16:54, the range between the ships decreased to 12,900 yards (11,800 m), which enabledSeydlitz's secondary battery to enter the fray. She was close enough to the ships of the British 9th and 10th Destroyer Flotillas that her secondary guns could effectively engage them. The other four German battlecruisers employed their secondary battery against the British battlecruisers.[58]
Between 16:55 and 16:57,Seydlitz was struck by two heavy caliber shells fromQueen Mary. The first shell penetrated the side of the ship five feet above the main battery deck, and caused a number of small fires. The second shell penetrated the barbette of the aft superfiring turret. Four propellant charges were ignited in the working chamber; the resulting fire flashed up into the turret and down to the magazine. The anti-flash precautions that had been put in place after the explosion at Dogger Bank prevented any further propellant explosions. Regardless, the turret was destroyed and most of the gun crew had been killed in the blaze.[59]
By 17:25, the British battlecruisers were taking a severe battering from their German opponents.Indefatigable had been destroyed by a salvo fromVon der Tann approximately 20 minutes before, and Beatty sought to turn his ships away by 2 points in order to regroup, while theQueen Elizabeth-class battleships of the5th Battle Squadron arrived on the scene and provided covering fire. As the British battlecruisers began to turn away,Seydlitz andDerfflinger were able to concentrate their fire onQueen Mary. Witnesses reported at least 5 shells from two salvos hit the ship, which caused an intense explosion that ripped theQueen Mary in half. Shortly after the destruction ofQueen Mary, both British and German destroyers attempted to make torpedo attacks on the opposing lines. One British torpedo struckSeydlitz at 17:57. The torpedo hit the ship directly below the fore turret, slightly aft of where she had been mined the month before. The explosion tore a hole 40 feet long by 13 feet wide (12 m × 4.0 m), and caused a slight list. Despite the damage, the ship was still able to maintain her top speed, and kept position in the line.[60]
The leading ships of the German battle fleet had by 18:00 come within effective range of the British ships, and had begun trading shots with the British battlecruisers andQueen Elizabeth-class battleships. Between 18:09 and 18:19,Seydlitz was hit by a 380 mm (15 in) shell from eitherBarham orValiant. This shell struck the face of the port wing turret and disabled the guns. A second 380 mm shell penetrated the already disabled aft superfiring turret and detonated the cordite charges that had not already burned. The ship also had two of her 150 mm guns disabled from British gunfire, and the rear turret lost its right-hand gun.[61]
As the evening wore on, visibility steadily decreased for the German ships. Egidy later remarked:
"Visibility had generally become unfavorable. There was a dense mist, so that as a rule only the flashes of the enemy's guns, but not the ships themselves, could be seen. Our distance had been reduced from 18,000 to 13,000 yards. From north-west to north-east we had before us a hostile line firing its guns, though in the mist we could only glimpse the flashes from time to time. It was a mighty and terrible spectacle."[62]
At around 19:00, Beatty's forces were nearing the main body of the Grand Fleet, and to delay the discovery of the Grand Fleet's location by the German fleet, he turned his ships towards the German line, in order to force them to turn as well. This reduced the distance between the British and German battlecruisers from 14,000 to 12,000 yards (13,000 to 11,000 m). Visibility continued to favor the British, and the German battlecruisers paid the price. Over the next several minutes,Seydlitz was hit six times, primarily on the forward section of the ship. A fire started under the ship's forecastle. The smothering fire from Beatty's ships forced Hipper to temporarily withdraw his battlecruisers to the southwest. As the ships withdrew,Seydlitz began taking on more water, and the list to starboard worsened. The ship was thoroughly flooded above the middle deck in the fore compartments, and had nearly lost all buoyancy.[63]
By 19:30, the High Seas Fleet, which was by that point pursuing the British battlecruisers, had not yet encountered the Grand Fleet. Scheer had been considering retiring his forces before darkness exposed his ships to torpedo boat attack. He had not yet made a decision when his leading battleships encountered the main body of the Grand Fleet. This development made it impossible for Scheer to retreat, for doing so would have sacrificed the slower pre-dreadnought battleships of II Battle Squadron, while using his dreadnoughts and battlecruisers to cover their retreat would have subjected his strongest ships to overwhelming British fire. Instead, Scheer ordered his ships to turn 16 points to starboard, which would bring the pre-dreadnoughts to the relative safety of the disengaged side of the German battle line.[64]
Seydlitz and the other battlecruisers followed the move, which put them astern ofKönig. Hipper's badly battered ships gained a temporary moment of respite, and uncertainty over the exact location and course of Scheer's ships led AdmiralJellicoe to turn his ships eastward, towards what he thought was the likely path of the German retreat. The German fleet was instead sailing west, but Scheer ordered a second 16-point turn, which reversed course and pointed his ships at the center of the British fleet. The German fleet came under intense fire from the British line, and Scheer sentSeydlitz,Von der Tann,Moltke, andDerfflinger at high speed towards the British fleet, in an attempt to disrupt their formation and gain time for his main force to retreat. By 20:17, the German battlecruisers had closed to within 7,700 yards (7,000 m) ofColossus, at which point Scheer directed the ships to engage the lead ship of the British line.Seydlitz managed to hitColossus once, but caused only minor damage to the ship's superstructure. Three minutes later, the German battlecruisers turned in retreat, covered by a torpedo boat attack.[65]
A pause in the battle at dusk allowedSeydlitz and the other German battlecruisers to cut away wreckage that interfered with the main guns, extinguish fires, repair the fire control and signal equipment, and ready the searchlights for nighttime action. During this period, the German fleet reorganized into a well-ordered formation in reverse order, when the German light forces encountered the British screen shortly after 21:00. The renewed gunfire gained Beatty's attention, so he turned his battlecruisers westward. At 21:09, he sighted the German battlecruisers, and drew to within 8,500 yards (7,800 m) before opening fire at 20:20. In the ensuing melee,Seydlitz was hit several times; one shell struck the rear gun turret and other hit the ship's bridge. The entire bridge crew was killed and several men in the conning tower were wounded. The German ships returned fire with every gun available, and at 21:32 hit bothLion andPrincess Royal in the darkness. The maneuvering of the German battlecruisers forced the leading I Battle Squadron to turn westward to avoid collision. This brought the pre-dreadnoughts of II Battle Squadron directly behind the battlecruisers, and prevented the British ships from pursuing the German battlecruisers when they turned southward. The British battlecruisers opened fire on the old battleships; the German ships turned southwest to bring all of their guns to bear against the British ships.[66]
By 22:15, Hipper was finally able to transfer toMoltke, and then ordered his ships to steam at 20 knots (37 km/h) towards the head of the German line. OnlySeydlitz andMoltke were in condition to comply;Derfflinger andVon der Tann could make at most 18 knots (33 km/h), and so these ships lagged behind.Seydlitz andMoltke were in the process of steaming to the front of the line when the ships passed close toStettin, which forced the ship to drastically slow down to avoid collision. This forcedFrauenlob,Stuttgart, andMünchen to turn to port, which led them into contact with the 2nd Light Cruiser Squadron; at a range of 800 yards (730 m), the cruisers on both sides pummeled each other.KonteradmiralLudwig von Reuter decided to attempt to lure the British cruisers towardsMoltke andSeydlitz. Nearly simultaneously, the heavily damaged British cruisers broke off the attack. As the light cruisers were disengaging, a torpedo fired bySouthampton struckFrauenlob, and the ship exploded. The German formation fell into disarray, and in the confusion,Seydlitz lost sight ofMoltke. The ship was no longer able to keep up withMoltke's 22 knots, and so detached herself to proceed to the Horns Reef lighthouse independently.[67]
At 00:45,Seydlitz was attempting to thread her way through the British fleet, but was sighted by the dreadnoughtAgincourt and noted as a "ship or Destroyer".Agincourt's captain did not want to risk giving away his ship's position, and so allowed her to pass.[68] By 01:12,Seydlitz had managed to slip through the British fleet, and she was able to head for the safety of Horns Reef.[69] At approximately 03:40, she scraped over Horns Reef, her speed having fallen to 7 knots (13 km/h; 8.1 mph). Both of the ship's gyro-compasses had failed, so the light cruiserPillau was sent to guide the ship home. By 15:30 on 1 June,Seydlitz was in critical condition; the bow was nearly completely submerged, and the only buoyancy that remained in the forward section of the ship was the broadside torpedo room. The ship had been turned around and steamed astern to relieve pressure on the badly strainedbulkheads in the flooded bow. Preparations were being made to evacuate the wounded crew when a pair of pump steamers arrived on the scene. The ships were able to stabilizeSeydlitz's flooding, and the ship managed to limp back to port. She reached the outer Jade river on the morning of 2 June, and on 3 June the ship entered Entrance III of the Wilhelmshaven Lock. At most,Seydlitz had been flooded by 5,308 tonnes (5,224 long tons) of water.[70][71]
Close to the end of the battle, at 03:55, Hipper transmitted a report to Scheer informing him of the tremendous damage his ships had suffered. By that time,Derfflinger andVon der Tann each had only two guns in operation,Moltke was flooded with 1,000 tons of water, andSeydlitz was severely damaged. Hipper reported: "I Scouting Group was therefore no longer of any value for a serious engagement, and was consequently directed to return to harbor by the Commander-in-Chief, while he himself determined to await developments off Horns Reef with the battlefleet."[72] In the course of the battle,Seydlitz was hit 21 times by heavy-caliber shells, twice by secondary battery shells, and once by a torpedo. The ship suffered a total of 98 of her crew killed and 55 wounded.[73]Seydlitz herself fired 376 main battery shells and scored approximately 10 hits.[70]
On 15 June 1916, repair work toSeydlitz began in the Imperial Dockyard in Wilhelmshaven, and continued until 1 October. The ship then underwent individual training, and rejoined the fleet in November. With his previous flagshipLützow at the bottom of the North Sea, Hipper again raised his flag inSeydlitz, though by this time, Hipper used the old light cruiserNiobe as his headquarters while in port. On 4 November,Seydlitz andMoltke, along with II Division,I Battle Squadron,III Battle Squadron, and the new battleshipBayern sailed toBovbjerg on the Danish coast, in order to retrieve the strandedU-boatsU-20 andU-30. Two German battleships were torpedoed by a British submarine during the operation, which saw only one of the U-boats recovered.Seydlitz and the rest of the fleet took a much less active role through 1917, being used primarily to defend the German Bight. In November 1917, the new battlecruiserHindenburg replacedSeydlitz as the group flagship. The same month, KzSWilhelm Tägert relieved Egidy as the ship's captain.[70][74]
Scheer had begun to use light surface forces to attack British convoys to Norway beginning in late 1917. As a result, the Royal Navy attached a squadron of battleships to protect the convoys, which presented Scheer with the possibility of destroying a detached squadron of the Grand Fleet. Scheer remarked that "A successful attack on such a convoy would not only result in the sinking of much tonnage, but would be a great military success, and would ... force the English to send more warships to the northern waters."[75] Scheer instituted strict wireless silence in preparation for the planned attack. This denied the British the ability to intercept and decrypt German signals, which had previously been a significant advantage. The operation called for Hipper's battlecruisers to attack the convoy and its escorts on 23 April while the battleships of the High Seas Fleet stood by in support.[75] At 05:00 on 23 April 1918, the High Seas Fleet left harbor with the intention of intercepting one of the heavily escorted convoys.[76]
Hipper's forces were 60 nmi (110 km; 69 mi) west ofEgerö, Norway, by 05:20 on 24 April. Despite the success in reaching the convoy route undetected, the operation failed due to faulty intelligence. Reports from U-boats indicated to Scheer that the convoys sailed at the start and middle of each week, but a west-bound convoy had leftBergen on Tuesday the 22nd and an east-bound group leftMethil, Scotland, on the 24th, a Thursday. As a result, there was no convoy for Hipper to attack. The same day, one ofMoltke's screws slipped off, which caused serious damage to the power plant and allowed 2,000 metric tons (2,000 long tons; 2,200 short tons) of water into the ship.Moltke was forced to break radio silence in order to inform Scheer of the ship's condition, which alerted the Royal Navy to the High Seas Fleet's activities. Beatty sortied with a force of 31 battleships and four battlecruisers, but was too late to intercept the retreating Germans. The Germans reached their defensive minefields early on 25 April, though approximately 40 nmi (74 km; 46 mi) off HelgolandMoltke was torpedoed by the submarineE42, though she successfully returned to port.[77]
Seydlitz was to have taken part in what would have amounted to the"death ride" of the High Seas Fleet shortly before the end of World War I. The bulk of the High Seas Fleet was to have sortied from their base in Wilhelmshaven to engage the British Grand Fleet; Scheer—by now theGroßadmiral of the fleet—intended to inflict as much damage as possible on the British navy, in order to retain a better bargaining position for Germany, whatever the cost to the fleet.[78] While the fleet was consolidating in Wilhelmshaven, war-weary sailors began deserting en masse. AsVon der Tann andDerfflinger passed through the locks that separated Wilhelmshaven's inner harbor and roadstead, some 300 men from both ships climbed over the side and disappeared ashore.[79]
On 24 October 1918, the order was given to sail from Wilhelmshaven. Many of the war-weary sailors felt the operation would disrupt the peace process and prolong the war. Starting on the night of 29 October, sailors on several battleshipsmutinied; three ships from III Squadron refused to weigh anchors, and acts of sabotage were committed on board the battleshipsThüringen andHelgoland. The unrest ultimately forced Hipper and Scheer to cancel the operation.[80] Informed of the situation, the Kaiser stated "I no longer have a navy."[81] The Wilhelmshaven mutiny spread to Kiel, and fueled a largerGerman Revolution that continued after the end of the war. Germany's military position was hopeless, and so GeneralsPaul von Hindenburg andErich Ludendorff convinced the government to sign theArmistice to end the war.[82]
Following the capitulation of Germany in November 1918, most of the High Seas Fleet, under the command of Reuter, were interned in the British naval base in Scapa Flow.[83] Prior to the departure of the German fleet, AdmiralAdolf von Trotha made clear to Reuter that he could not allow the Allies to seize the ships, under any conditions. The fleet rendezvoused with the British light cruiserCardiff, which led the ships to the Allied fleet that was to escort the Germans to Scapa Flow. The massive flotilla consisted of some 370 British, American, and French warships. Once the ships were interned, their guns were disabled through the removal of their breech blocks, and their crews were reduced to 200 officers and men.[84]
The fleet remained in captivity during the negotiations that ultimately produced theTreaty of Versailles. Reuter believed that the British intended to seize the German ships on 21 June 1919, which was the deadline for Germany to have signed the peace treaty. Unaware that the deadline had been extended by two days, Reuterordered the ships to be sunk at the next opportunity. On the morning of 21 June, the British fleet left Scapa Flow to conduct training maneuvers, and at 11:20 Reuter transmitted the order to his ships.[85]Seydlitz slipped beneath the surface at 13:50. On her side and on the bottom in 22 meters of water the wreck was frequently mistaken for a small island, and was sold in this condition as scrap to the salvage firm of Cox and Danks, led byErnest Cox, along with a battleship and twenty-six destroyers.[7]
SalvagingSeydlitz also proved difficult, as the ship sank again during the first attempt to raise her, wrecking most of the salvage equipment. Undaunted, Cox tried again, ordering that when she was next raised, news cameras would be there to capture him witnessing the moment. The plan nearly backfired whenSeydlitz was accidentally refloated while Cox was holidaying in Switzerland. Cox told the workers to sink her again, then returned to Britain to be present asSeydlitz was duly refloated a third time.[86] The ship was raised on 2 November 1928, and while still inverted was towed south to be scrapped in Rosyth by 1930.Seydlitz's bell is on display at theLaboe Naval Memorial.[7] One of the ship's 15 cm guns, which had been removed in 1916, was later mounted aboard thecommerce raiderKormoran duringWorld War II.[87]
