For almost four desperate years, from 1939 to mid-1943, the British and American navies fought a savage, losing battle against German submarine wolfpacks. The Allies might never have turned the tide of that historic battle without an intelligence coup, and the race to break the German U-boat codes is one of the last great untold stories of World War II. David Kahn, the world's leading historian of cryptology, brings to life this tense, behind-the-scenes drama for the first time.
Seizing the Enigma provides the definitive account of how British and American code-breakers fought a war of wits against Nazi naval communications-and helped lead the Allies to victory in the crucial Battle of the Atlantic.
