Station X: The Codebreakers of Bletchley Park - Hardcover

Station X tells the true story of the amazing achievements of the codebreakers working at Bletchley Park in the Second World War.
In 1939 several hundred people - students, professors, international chess players, junior military officers, actresses and debutantes - reported to a Victorian mansion in Buckinghamshire: Bletchley Park. This was to be 'Station X', the Allies' top-secret centre for deciphering enemy codes.
Their task was to break the ingenious Enigma cypher used for German high-level communications. The settings for the Enigma machine changed continually and each day the German operators had 159 million million million different possibilities. Yet against all odds this gifted group achieved the impossible, coping with even greater difficulties to break Shark, the U-Boat Enigma, and Fish, the cypher system used by Hitler to talk to his generals.
Station X is also the story of the people involved from leading codebreakers such as Alan Turing, father of the modern computer, to the female operators who intercepted the messages.
