In November 1914, she transferred to the Baltic Sea to conduct operations against the Russian Navy. On 24 January 1915, she ran aground near Steinort while on a mission to bombard the naval base at Libau. The ship was soon refloated.

On 2 July 1915, the British submarine E9  torpedoed and badly damaged Prinz Adalbert  near Gotland Island. On 23 October 1915, E8  torpedoed Prinz Adalbert  20 miles west of Libau. The magazine exploded and the ship sank with the loss of 672 crew. There were only three survivors

Service history: Built by Kaiserliche Werft Wilhelmshaven in Wilhelmshaven, Hindenburg was the last battlecruiser completed for the Imperial German Navy. She was laid down 30 June 1913 and launched on 1 August 1915. Commissioned 10 May 1917, she was fully operational by 20 October 1917, too late to see any action in World War I. Like Lützow she was armed with two more of the 15 cm (5.9"/45 cal) and four 60 cm (23.6 in) torpedo tubes instead of the four 50 cm (19.7 in) ones in Derfflinger.
She was scuttled at Scapa Flow on 21 June 1919, and finally sank at 1700 hrs. An attempt to raise her was done in 1926 which proved unsuccessful, and she sank again. On 23 July 1930 another attempt was made to raise her, this time successfully. From 1930 to 1932 she was scrapped at Rosyth.
