With the fleet assembled Admiral Eberhardt attempted to pursue the enemy battlecruiser, but was unsuccessful. On 1 August 1915 she, and all the other pre-dreadnoughts, were transferred to the 2nd Battleship Brigade, after the dreadnought had entered service. On 1 October the new dreadnought provided cover while "Ioann Zlatoust" and "Pantelimon" bombarded Zonguldak and "Evstafi" shelled the nearby town of Kozlu. Both "Evstafi"-class ships participated in the second bombardment of Varna in May 1916. "Evstafi" and "Ioann Zlatoust" were reduced to reserve in March 1918 in Sevastopol. Immobile, they were captured there by the Germans in May 1918 and "Evstafi" was subsequently used by them as an accommodation hulk. Both ships were handed over to the Allies the following December. The British wrecked both ships' engines on 22–24 April 1919 when they left the Crimea to prevent the advancing Bolsheviks from using them against the White Russians. They were captured by both sides during the Russian Civil War, but were abandoned by the White Russians when they evacuated the Crimea in November 1920. "Evstafi" was renamed "Revoliutsiia" ("Revolution") on 6 July 1921. The ships were scrapped in 1922–23, although they were not removed from the Navy List until 21 November 1925.
