Christian Lamb returned from a year in France just before war broke out and quickly joined the Wrens (Women's Royal Naval Service). She was initially employed as a Coder but switched to plotting, which involved plotting the locations of all the ships and planes on a huge board. She served in this role initially in London, then Plymouth and Belfast before returning to southern England in the run-up to D-Day. She relates many light-hearted anecdotes: enjoying lunchtime concerts in the National Gallery when she was working at the Wren Headquarters in Trafalgar Square; experiencing several close encounters with bombings during the blitz; shopping in the Republic of Ireland where there were less restrictions. Throughout the war, she and her colleagues maintained a strong sense of patriotism and determination, inspired by Churchill's speeches. Despite the dangers, they never considered the possibility of losing the war.

Colette Cook tells of her work at Bletchley Park operating the Bombe machines whose function was to find the daily key settings of the Enigma machines used by the Germans during WWII to transmit encrypted messages. Colette joined the WRNS (Wrens) as soon as she was able, and following a period of basic training, applied for a mysterious posting ‘P5’. It transpired that this was shorthand for HMS Pembroke V, a cover term for WRNS being posted to Eastcote (an outstation of Bletchley) to train as Bombe operators. In this engaging interview, Colette explains how, after signing the Official Secrets Act, she learned to load the bombe with the coloured wheels and then set about the difficult job of plugging up the back as directed by a ‘menu’. She describes the work as monotonous, physically demanding, and very noisy, but her and her colleagues ‘just grinded away’. She tells of a sense of urgency, but stresses it was not panic, and a realisation that what they were doing was important. Reflecting on her time at Bletchley, Colette says that whilst ‘it all seems like a dream now’, she has an overarching feeling of pride in the part she played to crack the German cypher.

When war broke out, 14-year-old Joy Aylard was evacuated to the countryside for two happy years, before leaving school and returning to London to study at college until she was old enough to join up. As soon as she could, she joined the WRNS and was almost immediately sent to Bletchley Park’s Eastcote Outstation. Joy describes in detail the top-secret work involved in operating the Bombe machines to decipher German Enigma messages, remembering the boost to morale that came when successful results of their codebreaking efforts were filtered back to them. Reflecting on the intense secrecy surrounding the work, Joy explains that everyone just got used to not talking about what they were doing; not even Joy’s father knew what her job entailed! Joy’s reflections on her time during the war allow us a vivid glimpse into life behind the walls at Bletchley Park, and the technical skill, dedication and discretion of all who worked there and played such a pivotal role in the Allied war effort.
