Speaker: Mike Chapman.
Tens of thousands of wireless and cable messages sent by Germany and its allies were intercepted by the British, who then broke the codes and ciphers.
Two British organisations were involved, the Admiralty’s Room 40 (named after one of its offices in the Admiralty’s building in Whitehall) and the War Office’s MI1(b) (which worked closely with interception and codebreaking units on the Western and other war fronts.
The existence of Room 40 became public knowledge in the years after the war, though details of the existence of MI1(b) were kept secret for much longer.
