Their story begins with the start of World War II which began with the invasion of Poland by Nazi Germany. This came as a shock to British Prime Minister Neville Chamberlain who had brokered what he believed was a permanent peace with Hitler. Germany was not to invade any other European countries after annexing Czechoslovakia in 1938. But when Germany invaded Poland, breaking the treaty with Britain, Chamberlain was forced to declare war on Germany.
With the declaration of war, many government agencies were moved to the countryside to protect them. One such agency was the Government Code and Cipher School (GC&CS), part of the Secret Intelligence Service. Their new location was a country estate fifty miles from London, called Bletchley Park. It was given the code name, Station X. It's purpose was to break German codes and ciphers so as to learn the German military plans. Thousands of lives were at stake.
It all began at the coastal village of Withernsea with the arrival of a dozen young women at St. Leonard's Hotel. One of those women was eighteen-year-old Patricia Owtram who was stationed there as a wireless radio operator to listen to German naval traffic in the Baltic and North Seas.
In 1940, eighteen-year-old Jane Hughes, the eighteen-year-old daughter of Lord and Lady Hughes was to be a debutante. But Jane did not want the parties, dances, or dinners. What she wanted to was to be a part of the war effort. It was a letter from a former classmate inviting her to join them at Bletchley that changed everything. After being sworn to secrecy, Jane was assigned to Hut 6 where she worked to break Enigma codes sent by the Luftwaffe and the Wehrmacht.
Eighteen-year-old Mavis Lever quit school to help in the war effort. Fluent in German, she was assigned to Cottage 3 at Bletchley, breaking Enigma ciphers from the Italian Navy Alfred "Dilly" Knox figured if she could speak German, she could learn Italian. He was a Greek scholar and pioneering cryptographer.
Sarah Norton, the eighteen-year-old daughter of the 6th Lord Grantley received a mysterious letter requesting her to Station X at Bletchley Park, Buckinghamshire in four days from an unknown Commander Travis. Sarah had been sent abroad two years earlier to learn German in Munich and was familiar with Hitler and his Nazi party. Now at Bletchley Park, and sworn to the utmost secrecy, Sarah was assigned to Hut 4, part of the German Naval Section, working as an Indexer in the Index Room. She scrutinized decrypts from the Kriegsmarine and wrote key information on index cards.
By 1942, the war office now required all able-bodied British women to do war work. Seventeen-year-old Diana Payne was sent to the Wren (Women's Royal Navy Service) training camp in New College, Hampstead and then on to Bletchley Park. There she was assigned to Hut 11A which held the Bombes - machines designed by Alan Turing to break each day's new Enigma setting. The Bombes required two tall girls to attend to them, using a menu which described how the machine was to plugged up and the order of the wheels. It was tiring and difficult work.
Gwen Davis, an eighteen-year-old from Bournemouth, joined the Women's Auxiliary Air Force (WAAF) in 1942. She was sent to Hut 10, Block A to work on deciphering Luftwaffe's communications not encrypted by Enigma. Instead these messages were encrypted using a cipher book.
By June of 1943, twenty-year-old Ann Williamson had completed her degree in mathematics. She was required to do war work and eventually ended up at Bletchley Park in the Machine Room converting cribs (or guesses at the Enigma's settings for the day) and cipher text into a diagram. These diagrams, called Menus, required the ability to solve puzzles. The Menu was then sent on to a Bombe outstation.
Near the end of June, 1944, eighteen-year-old Joanna Chorley along with nineteen other WRENS arrived at Bletchley Park. She was assigned to work in Block F with Colossus I, the world's first electronic computer. It was used to determine the first half of a FISH setting. FISH were the most important top level Nazi communications enciphered by the more complex Lorenz SZ40/42 machine.
Marion Graham was sent to work in Japanese Section I in Block F, typing up Japanese messages that were decrypted and translated into English. These were sent to American cryptographers in Washington, D.C. Private Charlotte Vine-Stevens was also sent to Block . A member of the ATS (Auxiliary Territorial Service), she was to paraphrase translated Japanese messages which were then passed on to commanders in the field.
By 1944, almost seven thousand people worked at Bletchley Park, deciphering 2500 army and air force messages every day including some 2000 naval messages. The contributions of the young women, who constituted about three quarters of the workforce cannot be overstated. They were vital to the success of D-Day and the winning of the war.
Discussion
The Enigma Girls is an informative book about the contributions of ten British teenage girls at Bletchley Park during World War II. Since The Enigma Girls covers the war period from 1939 to 1945, Fleming profiles ten young women working at Bletchley Park, against the backdrop of war. Major events of the war are described including the invasion of several European countries and the Blitz in 1940, the sinking of the German boat Bismarck, the bombing of Pearl Harbor in 1941, the invasion of Sicily and the Italian campaign in 1943, and D-Day in 1944. Oddly, the events of Dunkirk in 1941 are not mentioned.
Fleming opens with the back story of World War II and the declaration of war by British Prime Minister Neville Chamberlain in 1939. Chamberlain had hoped to avoid war by signing an agreement with Adolf Hitler after he annexed Czechoslovakia in 1938. Life in Britain suddenly and drastically changed as Fleming goes on to describe. One such change was the moving of GC&CS to Bletchley Park, code-named Station X.
Much has been made of the significant contributions of Alan Turing, Dillwyn Knox and others in breaking the Enigma code and their work at Bletchley Park. However, there were over seven thousand people working at Station X, many of them young women who made significant and mostly unrecognized contributions. Beginning with Patricia Owtram, who entered the war effort in 1930 as a wireless operator, Fleming highlights ten young women who were part of thousands would keep Station X functioning through the war. Some were the daughters of aristocracy while others were university students or recent high school graduates looking for something different. The young women are profiled in chronological order, as the war continued. Fleming describes their responsibilities, how their work was, unknown to them, interconnected to one another and what life was like for them during the war.
It is evident that many sacrifices were made for the war effort by these young women. The work was exhausting and often depressing. For example, resetting the Bombes was exhausting. They were noisy and smelly because of the oil used to lubricate the Bombe's spindles. Diana Payne soon had calloused hands and fingers covered with small cuts. Her work made her feel exhausted and lonely. "Many others experienced sleeplessness, hand tremors, loss of appetite, and nervousness. Some had breakdowns. Most worked on the edge of mental exhaustion. The long hours, the noise of the rotating wheels, and the intensity of the work put an enormous strain on the Wrens."
Not only could the work be difficult, but even life outside of Bletchley Park could be challenging. The young women who arrived at Bletchley Park were assigned billets or temporary housing. The quality of these billets varied; they could be comfortable and the family welcoming, or noisy, unfriendly and lacking in even the most basic amenities.
The young women working at Bletchley Park weren't able to see the entire picture and how their work helped others. The path of an enemy message from when it was sent by the enemy, to being intercepted and sent to Bletchley Park where cryptographers worked to decipher them is outlined by Fleming, midway through the book. With each profile, Fleming explains the tasks crucial to their work at Bletchley Park. Readers will learn about wireless, Morse code, the German Enigma machine, codes and ciphers, the British cipher machine called a Typex, how to break a cipher, indexing at Bletchley, decipher a message, the Bombes and how they worked and were reset each day, cribs, creating a Menu, enciphering a cipher, the German Lorenz SZ40/42, and the Colossus I - the first electronic machine. The work was complex, vast and crucial to the war effort. Fleming includes a wealth of black and white photographs of significant events in the war but also the few existing ones of Bletchley Park, and the machines used in the war effort.
Fleming definitely highlights not only the contributions of these ten young women in particular but of all the women who joined the war effort in Great Britain, as well as their personal sacrifices. The Enigma Girls is a thoroughly researched book that will engage not only those interested in World War II history, but also the many contributions made by women in the war, as well as codes and ciphers. Fleming has included an Author's Note, an extensive Bibliography, Source Notes for each of the chapters, Photograph and Illustration credits, and a detailed Index.
