Bletchley Park, Britain's key decryption centre during WWI, is known for the success of breaking the Nazi Enigma codes - experts have suggested that the Bletchley Park codebreakers may have shortened the war by as much as two years.

David Kenyon is the research historian at Bletchley Park. Recorded at the grounds, David and Dan walk through Bletchley’s latest exhibition, The Intelligence Factory. They uncover hidden stories from the height of Bletchley’s wartime operations and discuss the codebreakers’ significant contribution to the allied victory in the Battle of the Atlantic.
