Seelöwe: The German Invasion of Britain, 1940

From BoardGameGeek:

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.
