British Intelligence in the Second World War provides the only reliable account yet published--or ever likely to be published--of the part played by British intelligence in allied strategy and operations in the Second World War. No such account could have been written without the unrestricted access which was afforded to Professor Hinsley and his colleagues to the full range of British government intelligence records and to political and military archives of the war and before.
Sir Francis Harry Hinsley OBE, was an English historian and cryptanalyst. He worked at Bletchley Park during the Second World War and wrote widely on the history of international relations and British Intelligence during the Second World War. He was known as Harry Hinsley.
