was ordered under the provisional name , as a replacement for the old . She was
laid down on 22 July 1907 at the in
Wilhelmshaven, under construction number 30. Construction work proceeded under absolute secrecy; detachments of soldiers were tasked with guarding the shipyard itself, as well as contractors that supplied building materials, such as
Krupp. The ship was
launched on 7 March 1908; she was christened by
Princess Hilda of Nassau, and the ceremony was attended by Kaiser
Wilhelm II and
Prince Henry of the Netherlands, representing his wife's
House of Orange-Nassau.
Fitting-out work was delayed significantly when a dockyard worker accidentally removed a blanking plate from a large pipe, which allowed a significant amount of water to flood the ship. The ship did not have its
watertight bulkheads installed, so the water spread throughout the ship and caused it to list to port and sink to the bottom of the dock. had also not had her bilge pumps installed yet, which delayed repairs. The ship had to be pumped dry and cleaned out, which proved to be a laborious task. The ship was completed by the end of September 1909. She was
commissioned into the High Seas Fleet on 1 October 1909, and
sea trials commenced immediately. Her first commander was (KzS—Captain at Sea)
Christian Schütz. On 16 October 1909, and her sister participated in a ceremony for the opening of the new third entrance in the Wilhelmshaven Naval Dockyard. They took part in the annual maneuvers of the
High Seas Fleet in February 1910 while still on trials. finished her testing and evaluation on 3 May and joined
I Battle Squadron of the High Seas Fleet, replacing the old
pre-dreadnought battleship . Over the next four years, the ship participated in the regular series of squadron and fleet maneuvers and training cruises. Immediately after entering service in May,
Nassau and the rest of the fleet conducted training maneuvers in the Kattegat. These were in accordance with Holtzendorff's strategy, which envisioned drawing the Royal Navy into the narrow waters there. The annual summer cruise was to Norway, and was followed by fleet training, during which another fleet review was held in
Danzig on 29 August. In September, KzS
Gisberth Jasper relieved Schütz as the ship's captain. A training cruise into the Baltic followed at the end of the year. in
Kiel before the war In March 1911, the fleet conducted exercises in the
Skagerrak and Kattegat. and the rest of the fleet received British and American naval squadrons at Kiel in June and July. The year's autumn maneuvers were confined to the Baltic and the Kattegat. Another fleet review was held afterward, during the exercises for a visiting Austro-Hungarian delegation that included
Archduke Franz Ferdinand and Admiral
Rudolf Montecuccoli. won the Kaiser's (Shooting Prize) for excellent shooting in the 1911 training year. In mid-1912, due to the
Agadir Crisis, the summer cruise was confined to the Baltic, to avoid exposing the fleet during the period of heightened tension with Britain and France. KzS
Ludolf von Uslar took command of the ship in October. won the for a second time in 1912. A training cruise in the Baltic took place late in the year. The training program for 1913 proceeded in much the same pattern as in previous years. On 14 July 1914, the annual summer cruise to Norway began. The threat of war caused Kaiser Wilhelm II to cancel the cruise after two weeks, and by the end of July the fleet was back in port. War between
Austria-Hungary and
Serbia broke out on the 28th, and in the span of a week all of the major European powers had joined the conflict.
World War I participated in most of the fleet advances into the North Sea throughout the war. The first operation was conducted primarily by Rear Admiral
Franz von Hipper's
battlecruisers; the ships bombarded the English coastal towns of
Scarborough, Hartlepool, and Whitby on 15–16 December 1914. A German battlefleet of 12 dreadnoughts—including —and eight pre-dreadnoughts sailed in support of the battlecruisers. On the evening of 15 December, they came to within of an isolated squadron of six British battleships. Skirmishes in the darkness between the rival
destroyer screens convinced the German fleet commander, Admiral
Friedrich von Ingenohl, that the entire
Grand Fleet was deployed before him. Under orders from the Kaiser to not risk the fleet, Ingenohl broke off the engagement and turned the battlefleet back towards Germany. next took part in the fleet advance on 24 January 1915 to support I Scouting Group after it had been ambushed by the British
1st and
2nd Battlecruiser Squadrons during the
Battle of Dogger Bank, though she again saw no action, as the battle had ended before the High Seas Fleet arrived late in the afternoon. Following the loss of the
armored cruiser at the Battle of Dogger Bank, the Kaiser removed Ingenohl from his post on 2 February. Admiral
Hugo von Pohl replaced him as commander of the fleet. Pohl conducted a series of fleet advances in 1915 in which took part; in the first one on 29–30 March, the fleet steamed out to the north of
Terschelling and return without incident. Another followed on 17–18 April, where the fleet covered a mining operation by II Scouting Group. Three days later, on 21–22 April, the High Seas Fleet advanced towards the
Dogger Bank, though again failed to meet any British forces. The fleet next went to sea on 29–30 May, advancing as far as
Schiermonnikoog before being forced to turn back by inclement weather. On 10 August, the fleet steamed to the north of
Helgoland to cover the return of the
auxiliary cruiser . That month, KzS
Max Köthner replaced Uslar as s captain.
Battle of the Gulf of Riga In August 1915, the German fleet attempted to clear the
Gulf of Riga to facilitate the capture of
Riga by the
German Army. To do so, the German planners intended to drive off or destroy the Russian naval forces in the area, which included the pre-dreadnought battleship and a number of gunboats and destroyers. The German naval force would also lay a series of
minefields in the northern entrance to the gulf to prevent Russian naval reinforcements from being able to enter the area. The fleet that assembled for the assault included
Nassau and her three sister ships, the four s, and the battlecruisers , , and . The force would operate under the command of now-Vice Admiral Hipper. The eight battleships were to provide cover for the forces engaging the Russian flotilla. The first attempt on 8 August was unsuccessful, as it had taken too long to clear the Russian minefields to allow the minelayer to lay a minefield of her own. On 16 August 1915, a second attempt was made to enter the gulf: and , four light cruisers, and 31 torpedo boats managed to breach the Russian defenses. On the first day of the assault, the German
minesweeper T 46 was sunk, as was the destroyer
V 99. The following day, and engaged in an artillery duel with , resulting in three hits on the Russian ship that forced her to retreat. By 19 August, the Russian minefields had been cleared, and the flotilla entered the gulf. Reports of Allied
submarines in the area prompted the Germans to call off of the operation the following day. and remained in the Gulf until 21 August, and while there assisted in the destruction of the
gunboats and . Admiral Hipper later remarked that, "To keep valuable ships for a considerable time in a limited area in which enemy submarines were increasingly active, with the corresponding risk of damage and loss, was to indulge in a gamble out of all proportion to the advantage to be derived from the occupation of the Gulf
before the capture of Riga from the land side."
Return to the North Sea By the end of August and the rest of the High Seas Fleet had returned to their anchorages in the North Sea. The next operation conducted was a sweep into the North Sea on 11–12 September, though it ended without any action. Another sortie followed on 23–24 October during which the German fleet did not encounter any British forces. In November, KzS
Robert Kühne relieved Köthner aboard , though he would remain in command for just three months. On 12 January 1916, Admiral
Reinhard Scheer replaced Pohl as the fleet commander; Scheer continued the aggressive fleet strategy of his predecessors. On 4 March 1916, , , , and steamed out to the Amrumbank to receive the auxiliary cruiser , which was returning from a raiding mission. was present during the fleet advance on 5–7 March, though this too ended without action. Further sorties were conducted on 26 March, 2–3 April, and 21–22 April, but none resulted in action with British forces. A bombardment mission followed two days later; joined the battleship support for Hipper's battlecruisers while they
attacked Yarmouth and Lowestoft on 24–25 April. During this operation, the battlecruiser was damaged by a British mine and had to return to port prematurely. Due to poor visibility, the operation was soon called off, leaving the British fleet no time to intercept the raiders.
Battle of Jutland took part in the inconclusive Battle of Jutland on 31 May – 1 June 1916, in II Division of I Battle Squadron. For the majority of the battle, I Battle Squadron formed the center of the
line of battle, behind Rear Admiral Behncke's III Battle Squadron, and followed by Rear Admiral Mauve's elderly pre-dreadnoughts of
II Battle Squadron. was the third ship in the group of four, behind and ahead of ; was the squadron's flagship. When the German fleet reorganized into a nighttime cruising formation, the order of the ships was inadvertently reversed, and so was the second ship in the line, astern of . Between 17:48 and 17:52, eleven German dreadnoughts, including , engaged and opened fire on the British 2nd Light Cruiser Squadron; s target was the cruiser . is believed to have scored one hit on
Southampton, at approximately 17:50 at a range of , shortly after she began firing. The shell struck
Southampton obliquely on her port side, and did not cause significant damage. then shifted her guns to the cruiser ; firing ceased by 18:10. At 19:33, came into range of the British battleship ; her main guns fired briefly, but after the 180-degree turn by the German fleet, the British ship was no longer within reach. and the rest of I Squadron were again engaged by British light forces shortly after 22:00, including the light cruisers , , and . followed her sister in a 68° turn to starboard in order to evade any
torpedoes that might have been fired. The two ships fired on
Caroline and
Royalist at a range of around . The British ships turned away briefly, before turning about to launch torpedoes.
Caroline fired two at ; the first passed close to her bows and the second passed under the ship without exploding. At around midnight on 1 June, the German fleet was attempting to pass behind the British Grand Fleet when it encountered a line of British destroyers. came upon the destroyer , and in the confusion, attempted to ram her.
Spitfire tried to evade, but could not maneuver away fast enough, and the two ships collided. fired her forward 11-inch guns at the destroyer. They could not depress low enough for to be able to score a hit; nonetheless, the blast from the guns destroyed
Spitfires
bridge. At that point,
Spitfire was able to disengage from , and took with her a 6 m (20 ft) portion of s side plating. The collision disabled one of s 15 cm (5.9 in) guns, and left a 3.5 m (11.5 ft) gash above the waterline; this slowed the ship to until it could be repaired. During the confused action, was hit by two shells from the British destroyers, which damaged her searchlights and inflicted minor casualties. Shortly after 01:00, and encountered the British armored cruiser . opened fire first, and pummeled
Black Prince with a total of 27 heavy-caliber shells and 24 shells from her secondary battery. and joined in, followed by . The heavy fire quickly disabled the British cruiser and set her alight; following a tremendous explosion, she sank, taking her entire crew with her. The sinking
Black Prince was directly in the path of ; to avoid the wreck, the ship had to steer sharply towards III Battle Squadron. It was necessary for to reverse her engines to full speed astern to avoid a collision with . briefly lost contact with the rest of the battle fleet in the darkness, but she soon fell back into a position between the pre-dreadnoughts and . At around 03:00, several British destroyers attempted another torpedo attack on the German line. At approximately 03:10, three or four destroyers appeared in the darkness to port of ; at a range of between to , briefly fired on the ships before turning away 90° to avoid torpedoes. Following her return to German waters, , her sisters and , and the -class battleships and , took up defensive positions in the
Jade roadstead for the night. In the course of the battle, was hit twice by secondary shells, though these hits caused no significant damage. Her casualties amounted to 11 men killed and 16 men wounded. During the course of the battle, she fired 106 main battery shells and 75 rounds from her secondary guns. Repairs were completed quickly, and was back with the fleet by 10 July 1916.
Later operations Another fleet advance followed on 18–22 August, during which the I Scouting Group battlecruisers were to bombard the coastal town of
Sunderland in an attempt to draw out and destroy Beatty's battlecruisers. As only two of the four German battlecruisers were still in fighting condition, three dreadnoughts were assigned to the Scouting Group for the operation: , , and the newly commissioned . The High Seas Fleet, including , would trail behind and provide cover. At 06:00 on 19 August, was torpedoed by the British submarine north of Terschelling; the ship remained afloat and was detached to return to port. The British were aware of the German plans and
sortied the Grand Fleet to meet them. By 14:35, Admiral Scheer had been warned of the Grand Fleet's approach and, unwilling to engage the whole of the Grand Fleet just 11 weeks after the close call at Jutland, turned his forces around and retreated to German ports. The fleet advanced as far as the Dogger Bank on 19–20 October. The operation led to a brief action on 19 October, during which a British submarine torpedoed the cruiser . The failure of the operation (coupled with the action of 19 August) convinced the German naval command to abandon its aggressive fleet strategy. in favor of a resumption of the
unrestricted submarine warfare campaign On 21 December, ran aground in the mouth of the
Elbe. She was able to free herself, and repairs were effected in
Hamburg at the Reihersteig Dockyard until 1 February 1917. While the ship was still under repair in January, KzS
Victor Reclam arrived to take command of the ship. In late 1917, light forces of the High Seas Fleet began
interdicting British convoys to Norway, which prompted the British to detach battleships from the battle fleet to protect the convoys. The Germans were now presented with an opportunity for which they had been waiting the entire war: a portion of the Grand Fleet could be isolated and destroyed. Hipper planned the operation: the battlecruisers of
I Scouting Group, along with light cruisers and destroyers, would attack one of the large convoys, while the rest of the High Seas Fleet would stand by, ready to attack the British battleship squadron. At 05:00 on 23 April 1918,
Nassau and the rest of the fleet departed from the Schillig roadstead. Hipper ordered wireless transmissions be kept to a minimum, to prevent radio intercepts by British intelligence. At 06:10 the German battlecruisers had reached a position approximately southwest of
Bergen when the battlecruiser
Moltke lost her inner starboard propeller, which severely damaged the ship's engines. Despite this setback, Hipper continued northward. By 14:00, Hipper's force had crossed the convoy route several times but had found nothing. At 14:10, Hipper turned his ships southward. By 18:37, the German fleet had made it back to the defensive minefields surrounding their bases. It was later discovered that the convoy had left port a day later than expected by the German planning staff. , , and were formed into a special unit for
Operation Schlußstein, a planned occupation of
Saint Petersburg. On 8 August, took on 250 soldiers in Wilhelmshaven and then departed for the Baltic. The three ships reached the Baltic on 10 August, but the operation was postponed and eventually canceled. The special unit was dissolved on 21 August, and the battleships were back in Wilhelmshaven on the 23rd. and her three sisters were to have taken part in a
final fleet action at the end of October 1918, days before the
Armistice was to take effect. 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 the
Grand Admiral () of the fleet—intended to inflict as much damage as possible on the British navy, to improve Germany's bargaining position, despite the expected casualties. Many of the war-weary sailors felt that the operation would disrupt the peace process and prolong the war. On the morning of 29 October 1918, the order was given to sail from Wilhelmshaven the following day. Starting on the night of 29 October, sailors on and then on several other battleships
mutinied. The unrest ultimately forced Hipper and Scheer to cancel the operation. The following month, KzS
Hermann Bauer arrived to take command of the ship; he was to be s final captain.
Fate Following the German collapse that had resulted in the Armistice of 11 November 1918, a significant portion of the High Seas Fleet was interned in
Scapa Flow. and her three sisters were not among the ships listed for internment, so they remained at German ports. They had their guns disabled, along with the four
Helgoland-class battleships. Under the terms of the
Treaty of Versailles that formally ended the war in June 1919,
Nassau and the other dreadnoughts that had remained in Germany were to be surrendered to the Allies under Article 185. Negotiations between the Allies over which country received what vessels, and what those ships could be used for began in November. While final decisions were still being made, the Allies decided that the ships in question were to sail to either a British or French port, and accordingly, on 1 April 1920,
Nassau and
Ostfriesland sailed for
Rosyth, Britain, arriving on 5 April. On 7 April, was awarded to Japan; the Japanese had no need for the ship, so they sold her in June to British shipbreakers, who partially stripped useful equipment before re-selling
Nassau to shipbreakers in
Dordrecht, who in turn scrapped the ship in 1922. == Notes ==
