intelligence. When air chiefs held a postBattle meeting to thrash over the lessons
of the past few months, Dowding's chief rival, Trafford LeighMallory, sent his
squadron ...

British General Bernard Montgomery was another officer who often disregarded
Ultra intelligence. The two countries eventually signed secret agreements on
sharing the effort and results of their code breaking—a relationship that continues
to this day. Although the British did share some intelligence information with the
French, they did not share the Ultra secret or code- breaking technology with the
Russians. Occasionally, selected intelligence information such as advance
warning of ...

But there is one wartime secret which has not been released; indeed it is
probable that it never will be. It is the wartime work of the British Code and Cipher
School; in particular the method of penetration by them of the German machine
codes now known generally as Enigma: the 'Ultra Secret', which remains — still
secret. During the six years of the war, 10,000 men and women worked on
breaking the German military ciphers. The cover name for the department was '
