The Siege of Sevastopol also known as the Defence of Sevastopol (Russian: Оборона Севастополя, transliteration: Oborona Sevastopolya) or the Battle of Sevastopol (German: Schlacht um Sewastopol) was a military battle that took place on the Eastern Front of the Second World War. The campaign was fought by the Axis powers of Germany, Romania, and Italy against the Soviet Union for control of Sevastopol, a port in the Crimea on the Black Sea. On 22 June 1941 the Axis invaded the Soviet Union during Operation Barbarossa. Axis land forces reached the Crimea in the autumn of 1941 and overran 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 the Axis attack 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 the eastern Crimea was eliminated in May 1942.
