It was very intense and very concentrated. "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, who'd been operating while you were away, could go and get her meal. "You had half an hour off for a meal," said Bourne. There was little respite during a shift for the bombe operators, even during meal times. You had to brush out the wires on your drums so there wouldn't 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 were standing for the whole time." You worked in pairs and you and your checker would plug up the back of your machine, which was extremely complicated. 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.īourne said, "You didn't have to be rocket scientists but what you had to be was 125 percent accurate.

"We knew that every 24 hours the code was changed and that was why time and accuracy were of the absolute essence. We were breaking thousands of messages," Bourne said.

"I joined just around D-Day and at that time the traffic was tremendous.

If the crib and initial settings were good, then the bombe could return the information needed to crack the code within minutes. The bombe could check the possible ways the Enigma could have been set up incredibly rapidly, dismissing incorrect settings one at a time.

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. These settings were derived from cribs, which were best guesses at fragments of plain text-for example, standard openings such as weather reports-from the enciphered messages. His solution was the bombe, an electromechanical machine designed to emulate the workings of 36 Enigmas.īourne was a member of the Women's 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. 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. There were far too many to check by hand. On top of that, on an average day at Bletchley Park code-breakers were tasked with breaking between 2,000 and 6,000 messages of German, Italian, Japanese and Chinese origin.

The problem facing Britain and its allies early in the war was that the Enigma machine used to encrypt Nazi military traffic could scramble a message in 158 million million million ways, and each day the settings used would be changed. "That was exciting but standing in front of a machine for eight hours was not," she said.Īs 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.

These efforts produced Colossus, the world's first programmable electronic digital computer.ĭownload this article as a PDF (free registration required). The vital importance of preempting German plans led to a huge push to create machines that could crack ciphers at superhuman speeds. These servicewomen played a pivotal role in an operation that decrypted millions of German messages and which is credited with significantly shortening the war.

Today, the mansion in the heart of the southeast English countryside is famous for being where the brilliant mathematician Alan Turing cracked the Nazi's Enigma code.īecause Turing's individual achievements were so momentous, it's sometimes forgotten that more than 10,000 other people worked at the Government Code and Cypher School, of whom more than two-thirds were female. It was Ruth Bourne's 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. "I was given one sentence, 'We are breaking German codes, end of story'."
