The last of six programmes Still Secret
The best-kept secret of the Second World War was undoubtedly the story of how we in Britain broke the German codes. It is a story which has never been told in full, and many of the details are still secret. In the light of the information that is now coming out about the work of the Government Code and Gypher School at Bletchley Park, much of the history of the Second World War will need to be re-written.
Even more extraordinary, in their effort to decode high-level German cyphers, the mathematicians and engineers at Bletchley Park manufactured the world's first electronic digital computer which was built in 1943. Narrator WILLIAM WOOLLARD
