    The Polish code breakers

    Here is how the young Polish mathematicians broke the unbreakable Enigma and gave the Allies a priceless gift

      The first breaks into Enigma. In August 1939, the Government Codes & Ciphers School comes back to Bletchley Park for real just before the outbreak of War

      Find out how Dilly Knox and "his Girls" broke Enigma with the help of the gift from the Poles.

      Alan Turing and his Bombe

      Turing's crucial ideas for breaking Enigma.

      Explore the Bombe in Action See how menus were constructed and how a menu ran on the Bombe..
      For the "Anoraks" (Technically Skilled Superior Individuals!) here is a high speed Bombe Simulator which enables real code breaking to be done.

      Information Flow through Bletchley Park

      By 1944 Bletchley Park had evolved into a massive well oiled machine for producing vital intelligence to help the Allied war effort follow a German Enigma message through all the processes to break it, decipher it and deliver its intelligence content to the Allied field Commanders.
