The Siege of Sebastopol took place in 1942, after the Russian failure to re-take Kharkov.
The Germans had to take Sebastopol if they were to fulfill their aim in completing the southern arm of Operation Barbarossa - taking the oil fields of the Middle East.
Five German divisions were assigned the task of blockading Sebastopol from the land side and were supported in the air by VIII Fliegerkorps and Luftflotte IV.
