"Moltke" joined "Von der Tann" in the battlecruiser squadron upon her commissioning, and saw action against the British in the North Sea, including the Battle of Dogger Bank in January 1915, in addition to the coastal raids carried out in the first two years of the war. The ship also saw significant duty in the Baltic Sea against the Russian navy; in 1915 she was present at the Battle of the Gulf of Riga, where she was torpedoed by a British submarine, and in 1917, she returned to the Baltic as the flagship of the invasion force that conducted Operation Albion. "Moltke" was also interned in Scapa Flow at the end of the war and scuttled in 1919. "Goeben", on the other hand, was assigned to the Mediterranean in 1912 to serve as the flagship of the Mediterranean Division. At the outbreak of war in 1914, "Goeben" and the light cruiser evaded the British fleet and escaped to Constantinople, where they were transferred to the Ottoman Navy, though they remained under German command and with their original crews. The ship primarily operated in the Black Sea against the Russians, seeing combat at the Battle of Cape Sarych and the actions of 10 May 1915 and 8 January 1916. She attacked British forces outside the Dardanelles in 1918 and struck three mines. The ship continued in Turkish service until 1973 when she was sold for scrapping.
