Résumé: |
For an hundred years GCHQ - Government communications Headquarters - has been at the forefront of British secret statecraft. Famed for its codebreaking achievements at Bletchley Park against Enigma ciphers in the Second World War, GCHQ has interceped, interpreted ans disrupted the information networks of Britain's foes for a century, and yet it remains the least known and understood of British intelligence services. Based on unprecedented access to documents in GCHQ's archive, many of them hitherto classified, this is the first book to explain the entire history of one of the world's most potent intelligence agencies. Many of the major international episodes of the last century - including the retreat from empire, the Cold War and the Falklands conflict - become fully explicable only in the liht of secret intelligence and strategy, Behind the Enigma reveals the fascinating truth behind this most remarkable ans inscrutable of organisations. |
