when they withdrew from Sevastopol to prevent the advancing Bolsheviks from using her against the White Russians. She was abandoned when the Whites evacuated the Crimea in 1920 and was scrapped in 1923. Sissoi Veliky Sissoi Veliky was a pre-dreadnought battleship built for the Baltic Fleet in the 1890s. The ship's construction was marred by organizational, logistical and engineering problems and dragged on for more than five years. She was commissioned in October 1896 with an appalling number of design and construction faults, and only a few of them were fixed during her lifetime. Immediately after sea trials, Sissoi Veliky sailed to the Mediterranean to enforce the naval blockade of Crete during the Greco-Turkish War. In 1897 she suffered a devastating explosion of the aft gun turret that killed 21 men. After nine months in the docks of Toulon for repairs, the ship sailed to the Far East to reinforce the Russian presence there. In the summer of 1900, Sissoi Veliky supported the international campaign against the Boxer Rebellion in China. Sailors from Sissoi Veliky and Navarin participated in the defence of the International Legations in Beijing for more than two months. In 1902 the ship returned to Kronstadt for repairs, but very little was achieved until the early losses of the Russo-Japanese War caused the formation of the Second Pacific Squadron to relieve the Russian forces blockaded in Port Arthur. Sissoi Veliky sailed for the Far East with the rest of the Baltic battleships and participated in the Battle of Tsushima on 27 May 1905. She survived the daytime artillery duel with Admiral Heihachirō Tōgō's ships, but was badly damaged and taking on water. During the night Japanese destroyers scored a torpedo hit on the ship that damaged her steering. The next morning the ship was unable to maintain speed because of flooding, and her crew surrendered to Japanese armed merchant cruisers. The ship capsized later that morning with the loss of 47 crewmen. Petropavlovsk class The Petropavlovsk class, sometimes referred to as the Poltava class, was a class of three pre-dreadnought battleships built for the Imperial Russian Navy during the 1890s. They were transferred to the Pacific Squadron upon completion and based at Port Arthur before the start of the Russo-Japanese War of 1904–1905. All three ships participated in the Battle of Port Arthur on the second day of the war. sank two months after the war began
