At the end of World War I, the German fleet surrendered and was moved to Scapa Flow in the UK. In 1919, the German sailors scuttled their ships to prevent their use by the British enemy.
The battleship SMS Prinzregent Luitpold when refloated ended up keel up and was towed in that condition to be broken up for scrap in 1931.
