It was Ruth Bournes first job out of college, when, like thousands of other young British women during World War II, she was recruited to aid the Allied cipher breaking efforts at Bletchley Park. Today, the mansion in the heart of the southeast English countryside is famous for being where the brilliant mathematician Alan Turing cracked the Nazis Enigma code. Because Turings individual achievements were so momentous, its sometimes forgotten that more than 1. Government Code and Cypher School, of whom more than two thirds were female. Turing Bombe Program' title='Turing Bombe Program' />These servicewomen played a pivotal role in an operation that decrypted millions of German messages and which is credited with significantly shortening the war. The vital importance of preempting German plans led to a huge push to create machines that could crack ciphers at superhuman speeds. These efforts produced Colossus, the worlds first programmable electronic digital computer. However, the reality of running these electromechanical machines, setting rotors and plugging boards day in day out, was often less than thrilling, with the 1.

That was exciting but standing in front of a machine for eight hours was not, she said. As mundane as her daily routine was, it was vital in deciphering coded messages sent by the German army, navy and air force and helping the Allied forces turn the tide of war.

On top of that, on an average day at Bletchley Park code breakers were tasked with breaking between 2,0. German, Italian, Japanese and Chinese origin. There were far too many to check by hand. The code breaking needed to be automated, and it fell to British mathematician and father of the computer Alan Turing, with the help of the British Tabulating Machine Company, to devise the machine for the job. His solution was the bombe, an electromechanical machine designed to emulate the workings of 3. Enigmas. Bourne was a member of the Womens Royal Naval Service, known as the Wrens, who were charged with preparing the machines each day, turning the drums on the front and plugging up the boards at the back according to settings laid out in a menu. These settings were derived from cribs, which were best guesses at fragments of plain textfor example, standard openings such as weather reportsfrom the enciphered messages. If correct, these cribs would reveal some of the Enigma settings used to encode the message and provide a starting point for devising the remaining settings. The bombe could check the possible ways the Enigma could have been set up incredibly rapidly, dismissing incorrect settings one at a time. If the crib and initial settings were good, then the bombe could return the information needed to crack the code within minutes. I joined just around D Day and at that time the traffic was tremendous. We were breaking thousands of messages, Bourne said. We knew that every 2. You were really pressured. Like Bourne, many of the Navy Wrens operating the bombes were teenagers not long out of school, who found themselves working a punishing schedule, with very little margin for error. Bourne said, You didnt have to be rocket scientists but what you had to be was 1. You worked in pairs and you and your checker would plug up the back of your machine, which was extremely complicated. You had to brush out the wires on your drums so there wouldnt be short circuits, make sure the plugs at the back of the machine were pushed in and straight, and you had to be on the go for the eight hour shift, as you you were standing for the whole time. There was little respite during a shift for the bombe operators, even during meal times. You had half an hour off for a meal, said Bourne. The bombes were in a building with high brick walls, barbed wire and sentries, you had to get out from there, run to your canteen, grab your meal and run back and then your checker, whod been operating while you were away, could go and get her meal. It was very intense and very concentrated. We were young and learned quickly. The manor house at Bletchley Park as it appears today. Image shaunarmstrongmubsta. The high point of the day was getting a Job Up message, as it meant that their machine had broken a code, but she was always conscious one mistake could wreck their chances. Bourne said, You were a link in the chain and you couldnt be the weakest link. If youd made a mistake on your machineyou hadnt pushed a drum on properly or youd put a plug in incorrectlyand the machine wouldnt work, you would get a reprimand, If you had been more accurate, we might have brought the job up. Adding to the stress were the working conditions. Bombe operators worked round the clock, with teams spending one week working 8am to 4pm, the next 4pm until midnight and then midnight to 8am after that. The main pressure was the changing of the shifts, because you were always jetlagged. Your body clock was all over the place. I found it very hard to sleep during the daytime as there were not really proper blackout curtains, they were very flimsy and thin, said Bourne. Outside this serious work, however, Bourne and her fellow Wrens were pretty normal teenagers, with similar preoccupations to those of young people today. We had two lives really, Bourne said. One where you were in your workstation and you knew your bombe machine was ticking over and you brought a job up. But outside that it was being a normal girly in the Wrens.

Inside the code breaking factory If an Enigma code was broken early in the day, then the Allied forces would be able to decipher all messages sent by that arm of the military in the area until the Enigma settings were changed at midnight. But that didnt mean the bombes were switched off, there were always new intercepts and new messages to unscramble. The bombes never stopped. I think we broke two and a half million messages during the war, she said. The code breaking operation was spread over teams working in various huts around the manor house at Bletchley, with the bombe machines situated in outstations nearby. There were about 8,0. Each team generally knew no more than was necessary about what the other groups were doing. Teams worked in different huts on breaking the Enigma codes, focusing on the army and air force ciphers in one and the tougher naval encryption in another.
