German Invasion Plans for the British Isles 1940
A five year dossier of information of Britain, it's one of the only surviving copies found by the Allied forces as they invaded Berlin in 1945.
Don't get your hopes up folks it's more to do about us Brits, our class system along with roads and rail and the lay of the land etc, etc. More of an interest to anyone here in Britain.
