"Kahn, a noted historian of codebreaking, provides a specialized part of the story not
previously detailed. He underscores the strategic importance of submarine warfare in the Atlantic,
giving a balanced account of the ultimate importance of codebreaking in that arena. High drama at
sea seizing German codebooks and equipment and analytical genius ashore were essential. Kahn
describes both of these matching efforts expertly. Informed laypersons and specialists will find this
book valuable and intriguing. Recommended."Library Journal

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.
