In October 1941 after receiving a letter from some of the senior codebreakers decrying the lack of resources being afforded them, Prime Minister Winston Churchill directed:

‘Make sure they have all they want extreme priority and report to me that this has been done.’

From that moment on Bletchley Park began receiving a huge influx of resources and a major building programme ensued to create the space to house the ever increasing workforce. Brick and concrete blocks were built for staff, and Outstations created to house the growing number of ‘Bombe’ machines in use finding Enigma ‘Keys’. The Bombes were operated by Wrens, many of whom lived in requisitioned country houses such as Woburn Abbey. Codebreaking had been turned into an ‘industrial’ process.
