Passage: Thüringen 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 (Großadmiral) 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 29 October, sailors on Thüringen and then on several other battleships mutinied. Stokers turned off the boilers and refused to work. The following day, the torpedo boats B110 and B112 came alongside and the U-boat U-135 pointed her guns at the ship. A significant portion of the crew, 314 sailors and 124 stokers, were arrested and taken off the ship. This was not enough to stop the mutiny, which quickly spread throughout the fleet. The unrest ultimately forced Hipper and Scheer to cancel the operation. Informed of the situation, the Kaiser stated "I no longer have a navy".Following the capitulation of Germany in November 1918, most of the High Seas Fleet, under the command of Rear Admiral Ludwig von Reuter, was interned in the British naval base in Scapa Flow. Thüringen and her three sisters, along with the four Nassau-class battleships, were permitted to remain in Germany during the peace negotiations. On the morning of 21 June, the British fleet left Scapa Flow to conduct training maneuvers, and in their absence Reuter ordered the crews to scuttle the ten battleships and five battlecruisers interned at Scapa Flow. Thüringen was decommissioned on 16 December 1918 and used as a barracks ship while she remained in Germany. She was stricken from the naval register on 5 November 1919 and placed out of commission....
