The aviation historian presents a provocative analysis of WWII airborne operations to investigate what happened to Hitler's planned invasion of England. Did a German invasion or invasions take place along the shores of East Anglia in 1940? Though Operation Sealion, the intended invasion of southern England, never materialized, Hitler asked his forces to mount one, two or even three small invasions in 1940. This raises some provocative questions: Were the mass raids on London merely a diversion? Why have all the files on this most dramatic period in British history been kept hidden? Why have the instances involving setting fire to the sea and skirmishes around our coasts been covered up? Martin W. Bowman tells the full story of these remarkable events involving British defenders in the Army, Home Guard and Auxiliary Units and the invading Nazi military forces. This revealing history examines Allied and German airborne operations during the Second World War to piece together a truly riveting narrative. It is complimented by an extensive Appendix section and scores of previously unpublished photos.
