For Winston Churchill the men and women at Bletchley Park were ‘the geese the laid the golden eggs'', providing important intelligence that led to the Allied victory in the Second World War.At the peak of Bletchley''s success, a total of twelve thousand people worked there of whom more than eight thousand were women. These included a former ballerina who helped to crack the Enigma Code; a debutante working for the Admiralty with a direct line to Churchill; the convent girl who operated the Bombes, the top secret machines that tested Enigma settings; and the German literature student whose codebreaking saved countless lives at D-Day.All these women were essential cogs in a very large machine, yet their stories have been kept secret.In The Debs of Bletchley Park author Michael Smith, trustee of Bletchley Park and chair of the Trust''s Historical Advisory Committee, tells their tale. Through interviews with the women themselves and unique access to the Bletchley Park archives, Smith reveals how they came to be there, the lives they gave up to do ‘their bit'' for the war effort, and the part they played in the vital work of ‘Station X''.They are an incredible set of women, and this is their story.
