THIS BOOK tells the Real History of the heroic RAF moonlight attack on Germany's Ruhr Dams in May 1943, immortalised by the movie The Dambusters. The author's account is based on his interviews with Bomber Command officers and official British and German documents, and on exclusive access to the private papers and diaries of Dr Barnes Wallis—the British scientist who invented the unique "bouncing bomb" which smashed the dams. Originally published by The Sunday Express, London.
