SMS Ostfriesland

context: en: Ostfriesland and her three sisters were to have taken part in a final fleet action at the end of October 1918, just over 2 weeks before the Armistice was signed. The bulk of the High Seas Fleet was to have sortied from its base in Wilhelmshaven to engage the British Grand Fleet; Scheer—by now the Großadmiral (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. But 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 the 29th, sailors on Thüringen and then on several other battleships mutinied. The unrest ultimately forced Hipper and Scheer to cancel the operation. Informed of the situation, the Kaiser stated "I no longer have a navy". On 16 December, Ostfriesland was decommissioned and used as a barracks ship.

context: en: Ostfriesland was present during the fleet operation that resulted in the battle of Jutland, which took place on 31 May and 1 June 1916. The German fleet again sought to draw out and isolate a portion of the Grand Fleet and destroy it before the main British fleet could retaliate. During the operation, Ostfriesland was the lead ship in I Squadron's I Division and the ninth ship in the line, directly astern of the fleet flagship Friedrich der Grosse and ahead of her sister Thüringen. I Squadron was the center of the German line, behind the eight König- and Kaiser-class battleships of III Squadron. The six elderly pre-dreadnoughts of III and IV Divisions—II Battle Squadron—formed the rear of the formation. Ostfriesland flew the flag of Vizeadmiral (Vice Admiral) Erhardt Schmidt, the squadron commander during the battle and Scheer's deputy commander.Shortly before 16:00, the battlecruisers of I Scouting Group encountered the British 1st Battlecruiser Squadron under the command of David Beatty. The opposing ships began an artillery duel that saw the destruction of Indefatigable, shortly after 17:00, and Queen Mary, less than half an hour later. By this time, the German battlecruisers were steaming south to draw the British ships toward the main body of the High Seas Fleet. At 17:30, the crew of the leading German battleship, König, spotted both I Scouting Group and the 1st Battlecruiser Squadron approaching. The German battlecruisers were steaming to starboard, while the British ships steamed to port. At 17:45, Scheer ordered a two-point turn to port to bring his ships closer to the British battlecruisers and, a minute later, the order to open fire was given.While the leading battleships engaged the British battlecruiser squadron, Ostfriesland and ten other battleships fired on the British 2nd Light Cruiser Squadron. Ostfriesland, Kaiser, and Nassau engaged the cruiser Southampton, though only Nassau scored a hit. After about 15 minutes, Ostfriesland shifted fire to Birmingham and Nottingham, though again failed to hit her targets. Shortly after 19:15, the British dreadnought Warspite came into range; Ostfriesland opened fire at 19:25 with her main battery guns, at ranges of 10,800 to 15,000 yd (9,900 to 13,700 m). Ostfriesland claimed hits from her third and fourth salvos. Warspite was hit by a total of thirteen heavy shells during this period.By 20:15, the German battle line had faced the entire deployed Grand Fleet a second time. Scheer ordered a 180-degree turn at 20:17, which was covered by a charge by the battlecruiser squadron and a torpedo-boat attack. In order to hasten the maneuver, Schmidt ordered Ostfriesland to turn immediately without waiting for Thüringen behind him. This move caused some difficulty for the III Squadron ships ahead, though the ships quickly returned to their stations. At around 23:30, the German fleet reorganized into the night cruising formation. Ostfriesland was the eighth ship, stationed toward the front of the 24-ship line. An hour later, the leading units of the German line encountered British light forces and a violent firefight at close range ensued. Sometime around 01:10, the armored cruiser Black Prince stumbled into the German line. Thüringen illuminated the vessel with her spotlights and poured salvos of 30.5 cm rounds into the ship. Ostfriesland fired with her 15 cm guns and Kaiser fired both 30.5 cm and 15 cm guns. In the span of less than a minute, two massive explosions tore the cruiser apart and killed the entire 857-man crew.Despite the ferocity of the night fighting, the High Seas Fleet punched through the British destroyer forces and reached Horns Reef by 4:00 on 1 June. At 06:20, however, Ostfriesland struck a mine, previously laid by the destroyer HMS Abdiel on 4 May, on her starboard side. The ship hauled out of line, as the explosion was initially thought to have been a torpedo fired by a submarine. Ostfriesland fell behind the fleet and steamed at slow speed, screened by the destroyers V3, V5, and briefly by G11. By 10:40, the battleship had increased speed to 15 knots (28 km/h; 17 mph). Her anti-submarine escort was eventually reinforced by a floatplane, which spotted what it believed to be a British submarine at 12:20. Ostfriesland turned away, which caused the torpedo bulkhead, damaged slightly by the mine explosion, to tear open. More water entered the ship and caused a 4.75 degree list to starboard, forcing Ostfriesland to reduce speed again. The ship requested assistance from a pumping ship at 14:20, but by 14:45 the flooding was under control and the ship passed the Outer Jade Lightship. She was able to increase speed gradually to 10 knots (19 km/h; 12 mph), and at 18:15 she reached port in Wilhelmshaven. The mine tore a hole that measured 40 ft × 16 ft (12.2 m × 4.9 m) and allowed 500 t (490 long tons) of water into the ship. Further flooding occurred after the torpedo bulkhead damage at 12:20, though the full damage report has not survived. Ostfriesland was drydocked in Wilhelmshaven for repairs, which lasted until 26 July. In the course of the battle, Ostfriesland fired 111 rounds from her main battery, 101 shells from her 15 cm guns, and a single 8.8 cm shell. The only damage sustained was the mine that was struck on the morning of 1 June, which killed one man and wounded ten.
