The two ships, along with several other Ottoman vessels, raided Russian ports in October 1914, prompting a Russian declaration of war. The ships were renamed Midilli and Yavûz Sultân Selîm, respectively, and saw extensive service with the Ottoman fleet, primarily in the Black Sea against the Russian Black Sea Fleet.
