Categories: History
Seizing the Enigma (1991) by historian of cryptography David Kahn tells the story of the Allied effort to break the German naval Enigma cipher during the Second World War. Kahn describes how the Enigma machine worked, early Polish and British codebreaking, and the work at Bletchley Park. He shows how the capture of codebooks and machines from German ships and U-boats helped Allied codebreakers read U-boat communications and turn the Battle of the Atlantic.
