BBC Two - Timewatch, Code-Breakers: Bletchley Park's Lost Heroes

Documentary revealing how two men hacked into Hitler's personal super-code machine.

Documentary revealing the secret story of how two men hacked into Hitler's personal super-code machine. Their break turned the Battle of Kursk and powered the D-Day landings.

Documentary that reveals the secret story behind one of the greatest intellectual feats of World War II, a feat that gave birth to the digital age. In 1943, a 24-year-old maths student and a GPO engineer combined to hack into Hitler's personal super-code machine - not Enigma but an even tougher system, which he called his 'secrets writer'. Their break turned the Battle of Kursk, powered the D-day landings and orchestrated the end of the conflict in Europe. But it was also to be used during the Cold War - which meant both men's achievements were hushed up and never officially recognised.

BBC Two is a lively channel of depth and substance, carrying a range of knowledge-building programming complemented by great drama, comedy and arts.
