The Siege of Sevastopol took place from October 30, 1941 to July 4, 1942 between German forces and those of the Red Army, the Black Sea Fleet and elements of the Red Air Force over the control for the main Soviet Black Sea Fleet naval base during the Second World War. It is notable for use of German heavy artillery (200-800mm range) during the siege.

The German 11th Army, commanded by Erich von Manstein, besieged Sevastopol. At the time of the final assault in June 1942 the army consisted of 9 German infantry divisions (including 2 received during the battle) in two corps, and two Romanian rifle corps, plus various supporting elements including 150 tanks, several hundred aircraft, and one of the heaviest concentrations of artillery fielded by the Wehrmacht.

The defence of Sevastopol was provided mainly by the Black Sea Fleet and the Separate Coastal Army under Petrov (which had been shipped in from Odessa). The city garrison numbered one brigade, three regiments and 19 battalions of marine corps (ca. 23,000 men, ~150 field and coast guns and 82 aircraft), commanded by B. A. Borisov. 82 pillboxes with naval guns, 220 machine-gun earth-and-timber emplacements and pillboxes, 33 km of tank ditches, 56 km of wire entanglements and 9,600 mines were laid to improve the defence.
