Siege of Sevastopol (1941–1942)

[beebuster2000]

For an outstanding read, and particularly about the Crimean campaign my highest recommendation to the first hand account

“in deadly combat” by Gottlob Bidderman, antitank gunner and officer in the German Army. His first hand account of the battle is particularly horrifying and detailed.
