The best WWII general?

Wargames of Sealion have always come to the same conclusion, that whatever troops managed to get ashore would be lost as their supply routes were destroyed by the RAF and RN.

Yes Pannonian but that assumes there's some sort of organized opposition to resist the invaders, which there would have been by the time Sealion became a possibility. According to what I've read, there was very little available at the time of Dunkirk to resist a suprise attack.

When there is little or no equipment with which to resist the invaders, I think it would be a whole different ball game. You wouldn't need to get a really large force across the channel, and the supply problems would therefore be diminished.

So I don't think the idea is quite as fanciful as you and Assassin have suggested. It might have at least been worth a try.
