Seelöwe: The German Invasion of Britain, 1940 (1974)

Seelowe is a hypothetical wargame depicting Operation Sealion (in German: Seelöwe), the anticipated German invasion of the British Isles that would have followed a Luftwaffe victory in the Battle of Britain.

The map shows central and southern England and the English Channel.

Three invasion scenarios are re-created:
The Navy Plan involving a landing on a narrow front in south-eastern England.
The Army Plan which suggests that a landing on a broad front all along the south coast would have been possible.
The July Scenario in which the German army gambles on a small landing being sufficient to ensure victory.
