The Veterans of Bletchley Park and its Outstations

With the declaration of peace, the frenzy of Codebreaking activity ceased. The thousands who had worked at Bletchley Park departed. Some continued to use their remarkable expertise to break other countries' ciphers, working under a new name: the Government Communications Headquarters (GCHQ). As World War Two gave way to the Cold War, it was vital that Britain's former ally, the USSR, should learn nothing of Bletchley Park's wartime achievements. For decades, those involved with wartime Bletchley Park would remain silent about those achievements. 

In 1974 FW Winterbotham, who had worked on Ultra at wartime Bletchley Park, published a book called ‘The Ultra Secret’; an extensive, although at times inaccurate, account of the work and accomplishments of the Codebreaking hub. So the secret was out and the ban on talking about it was lifted although detail about ‘Britain’s Best Kept Secret’ emerged only gradually and sporadically over the years that followed.
