Operation Sealion was the Invasion of England by Germany's Armed forces in mid 1941.

Opposing Forces


After the Fall of France in 1940, the Führer celebrated victory over the Western Allies. He thought that after the Fall of France, Britain would also surrender. But with Winston Churchill as a main leader, Britain was still standing against the Germans.

The main German battle plan intended to capture all ports in southern England (see the map), and with their paratroopers and special commandos (Brandenburgers) they would achieve complete success and surprise.

Great Britain

Britain's Air Force, the RAF was shot down entirely during Unternehmen Adler (Battle of Britain), so Germany had complete air superiority over England. The British, who knew that an invasion after their air force being shot down would be imminent, they mustered all available forces to oppose the Germans.
