Seizing the enigma : the race to break the German U-Boat codes : 1939-1943

David Khan - already acknowledged as an expert historian of Intelligence in the Second World War after his earlier books 'The Codebreakers' and 'Hitler's Spies'- focuses here on the key struggle to win the Battle of the Atlantic. The Royal Navy and the RAF played vital roles, of course, in protecting Allied shipping from Nazi submarines and in capturing secret documents and cipher machines, but the real Intelligence battle was fought, and won, at Bletchley Park in rural England where a growing band of eccentrics struggled and finally broke the secret German codes. The size of the whole operation became staggering, but without it Britain's supply lines would have been able to onvade, or sue for peace. 'Seizing the Enigma' is brilliantly researched and written. It is fitting account and tribute of one of the key struggles of WWII. An account of one of the key campaigns of World War II, the Battle of the Atlantic. While the Royal Navy and RAF protected Allied shipping and captured secret documents and cipher machines, the Intelligence group at Bletchley Park fought the backroom war to unravel the German code, Enigma.
