The complete story of how the German Enigma codes were broken. Perfect for fans of THE IMITATION GAME, the new film on Alan Turing's Enigma code, starring Benedict Cumberbatch. Breaking the German Enigma codes was not only about brilliant mathematicians and professors at Bletchley Park. There is another aspect of the story which it is only now possible to tell. It takes in the exploits of spies, naval officers and ordinary British seamen who risked, and in some cases lost, their lives snatching the vital Enigma codebooks from under the noses of Nazi officials and from sinking German ships and submarines. This book tells the whole Enigma story: its original invention and use by German forces and how it was the Poles who first cracked - and passed on to the British - the key to the German airforce Enigma. The more complicated German Navy Enigma appeared to them to be unbreakable.

At its peak in January 1945, 10,000 people worked at Bletchley Park, reading 4000 messages a day, decrypting German and Japanese communications and helping the Allies to victory. But while we know that Bletchley was the centre of Britain’s World War II code-breaking, how did its efforts actually change the course of the war? Enigma: How Breaking the Code Helped Win World War II tells the story of Bletchley’s role in defeating U-boats in the Atlantic, breaking the Japanese codes, helping the Allies to victory in North Africa, deciphering the German military intelligence code, learning of most German positions in western Europe before the Normandy Landings, defeating the Italian Navy in the Mediterranean, and helping sink the German battleship Scharnhorst off Norway. In tracing these events, the book also delves into the stories of major Bletchley characters, ‘boffins’ such as Alan Turing and Gordon Welchman, and ‘Debs’ such as Joan Clarke and Margaret Rock. An accessible work of military history that ranges across air, land and naval warfare, the book also touches on the story of early computer science. Illustrated with 120 black-&-white and colour photographs, artworks and maps, Enigma: How Breaking the Code Helped Win World War II is an authoritative and novel perspective on WWII history.
