Krasny Kavkaz was a cruiser of the Soviet Navy that began construction during World War I, but was still incomplete during the Russian Revolution. Her design was heavily modified by the Soviets and she was completed in 1932. During World War II she supported Soviet troops during the siege of Odessa, siege of Sevastopol, and the Kerch–Feodosiya operation in the winter of 1941–42. She was awarded the Guards title on 3 April 1942. She was reclassified as a training ship in May 1947 before being expended as a target in 1952.

The siege of Sevastopol, also known as the defence of Sevastopol or the Battle of Sevastopol, was a military engagement that took place on the Eastern Front of the Second World War. The campaign was fought by the Axis powers of Germany and Romania against the Soviet Union for control of Sevastopol, a port in Crimea on the Black Sea. On 22 June 1941, the Axis invaded the Soviet Union during Operation Barbarossa, with Axis land forces reaching the Crimean peninsula in the autumn of 1941 and overrunning most of the area. The only objective not in Axis hands was Sevastopol. Several attempts were made to secure the city in October and November 1941. A major attack was planned for late November, but heavy rains delayed it until 17 December 1941. Under the command of Erich von Manstein, Axis forces were unable to capture Sevastopol during this first operation. Soviet forces launched an amphibious landing on the Crimean peninsula at Kerch in December 1941 to relieve the siege and force the Axis to divert forces to defend their gains. The operation saved Sevastopol for the time being, but the bridgehead in eastern Crimea was eliminated in May 1942.
