In May 1940, Nazi Germany was master of continental Europe. The only European power still standing was Great Britain - and the all-conquering German armed forces stood poised to cross the Channel. Following the destruction of the RAF fighter forces, the sweeping of the Channel of mines, and the wearing down of the Royal Naval defenders, two German army groups were set to storm the beaches of southern England.
The Crimea was one of the crucibles of the war on the Eastern Front, where first a Soviet and then a German army were surrounded, fought desperate battles, and were eventually destroyed. The fighting in the region was unusual for the Eastern Front in many ways, in that naval supply, amphibious landings, and naval evacuation played major roles, while both sides were also conducting ethnic cleansing as part of their strategy - the Germans eliminating the Jews and the Soviets purging the region of Tartars.
