The WWII historian’s bracingly accurate analysis of what might have happened if Hitler ordered Operation Sea Lion to breech the shores of England.

In June 1940, German troops gathered just across the English Channel, poised for the invasion of Britain. With France defeated and Britain cowed, Hitler seemed ready for his greatest gamble. In this compelling alternative history, the Germans launch the invasion that, in reality, was never more than a plan.

Landing between Dover and Hythe, German troops push inland supported by the Luftwaffe and the impregnable panzers, and strike out towards London. The British, desperate to defeat the invaders, rally and prepare for a crucial confrontation at Maidstone. Realistic, carefully researched and superbly written, Invasion is a classic of alternate history and a thought-provoking look at how Britain’s war might have been.
