'Briggs is an engaging and amiable guide though the mysteries of wartime cryptography . . . a fascinating account of an outstanding young man and his time at a quite remarkable institution.' Roger Moorhouse in BBC History magazine Lord Briggs has long been regarded as one of Britain's most important historians. However, until the publication of this remarkable book, he had never written about his time at Bletchley Park. Briggs himself did not tell his wife about his wartime career until the 1970s and his parents died without ever knowing about their son's contribution to the war effort. In this meticulously researched account he finally reveals the details of his life in Hut Six working as a code breaker alongside Alan Turing and Gordon Welchman. In addition to discussing the progress of the Allies' code breaking efforts and its impact on the war, Lord Briggs considers what the Germans knew about Bletchley and how they reacted to revelatory memoirs about the Enigma machine, which were not published until the 1970s. Packed with fascinating anecdotes, this is the gripping, revelatory story of an extraordinary young man in an extraordinary place.

The astonishing story of how the British codebreakers of Bletchley Park cracked the Nazi Enigma cyphers, cutting an estimated two years off the Second World War, never ceases to amaze. No one is better placed to tell that story than Michael Smith, whose number one bestseller Station X was one of the earliest accounts. Using recently released secret files, along with personal interviews with many of the codebreakers themselves, Smith now provides the definitive account of everything that happened at Bletchley Park during the war, from breaking the German, Italian and Japanese codes to creating the world’s first electronic computer. The familiar picture of Bletchley Park is of eccentric elderly professors breaking German codes, but in fact the vast majority of people who worked at Bletchley Park were young women. For them and for the young graduates plucked from Britain’s best universities who did the bulk of the day-to-day codebreaking, this was truly the time of their lives. The Secrets of Station X tells their story in full, providing an enthralling account of one of the most remarkable British success stories of all time.

INTERNATIONAL BESTSELLER Go behind the scenes of the top-secret setting of The Imitation Game A remarkable look at day-to-day life of the codebreakers whose clandestine efforts helped win World War II Bletchley Park looked like any other sprawling country estate. In reality, however, it was the top-secret headquarters of Britain’s Government Code and Cypher School—and the site where Germany’s legendary Enigma code was finally cracked. There, the nation’s most brilliant mathematical minds—including Alan Turing, whose discoveries at Bletchley would fuel the birth of modern computing—toiled alongside debutantes, factory workers, and students on projects of international importance. Until now, little has been revealed about ordinary life at this extraordinary facility. Drawing on remarkable first-hand interviews, The Secret Lives of Codebreakers reveals the entertainments, pastimes, and furtive romances that helped ease the incredible pressures faced by these covert operatives as they worked to turn the tide of World War II.

STATION X tells the true story, as it has never been told before, of the amazing achievements of the codebreakers working at Bletchley Park in the Second World War.In 1939, several hundred people - students, professors, international chess players, junior military officers, actresses and debutantes - reported to a Victorian mansion in Buckinghamshire: Bletchley Park. This was to be 'Station X', the Allies' top-secret centre for deciphering enemy codes. Their task was to break the ingenious Enigma code used for German high-level communications. The settings for the Enigma machine changed continually and each day the German operators had 159 million million million different possibilities. Yet against all the odds this gifted group achieved the impossible, coping with even greater difficulties to break Shark, the U-Boat Enigma, and Fish, the cypher system used by Hitler to talk to his guards.

For Winston Churchill the men and women at Bletchley Park were ‘the geese the laid the golden eggs’, providing important intelligence that led to the Allied victory in the Second World War. At the peak of Bletchley’s success, a total of twelve thousand people worked there of whom more than eight thousand were women. These included a former ballerina who helped to crack the Enigma Code; a debutante working for the Admiralty with a direct line to Churchill; the convent girl who operated the Bombes, the top secret machines that tested Enigma settings; and the German literature student whose codebreaking saved countless lives at D-Day. All these women were essential cogs in a very large machine, yet their stories have been kept secret. In The Debs of Bletchley Park and Other Stories author Michael Smith, trustee of Bletchley Park and chair of the Trust’s Historical Advisory Committee, tells their tale. Through interviews with the women themselves and unique access to the Bletchley Park archives, Smith reveals how they came to be there, the lives they gave up to do ‘their bit’ for the war effort, and the part they played in the vital work of ‘Station X’. They are an incredible set of women, and this is their story.

The untold story of Bletchley Park's key role in the success of the Normandy campaign Since the secret of Bletchley Park was revealed in the 1970s, the work of its codebreakers has become one of the most famous stories of the Second World War. But cracking the Nazis’ codes was only the start of the process. Thousands of secret intelligence workers were then involved in making crucial information available to the Allied leaders and commanders who desperately needed it. Using previously classified documents, David Kenyon casts the work of Bletchley Park in a new light, as not just a codebreaking establishment, but as a fully developed intelligence agency. He shows how preparations for the war’s turning point—the Normandy Landings in 1944—had started at Bletchley years earlier, in 1942, with the careful collation of information extracted from enemy signals traffic. This account reveals the true character of Bletchley's vital contribution to success in Normandy, and ultimately, Allied victory.

Bletchley Park, or Station X, was home to the most famous codebreakers of the Second World War. The 19th century mansion was the key center for cracking German, Italian and Japanese codes, providing the allies with vital information. After the war, many intercepts, traffic-slips and paperwork were burned (allegedly at Churchill's behest). The truth about Bletchley was not revealed until F. Winterbotham's The Ultra Secret was published in 1974. Against seemingly insurmountable odds, codebreakers including Alan Turing, Gordon Welchman and Jim Rose had devised methods to allow them to read enemy codes, often within hours of the messages being received. New technology was invented to automate the deciphering of messages. Colossus, the world's first semi-programmable computer was invented at Bletchley to aid the decoding of Lorenz ciphers, used by the German High Command to send their most highly-classified and importantßcommunications. The codebreakers also had tremendous success in defeating the Luftwaffe's AuKa codes. In The Secrets of Bletchley, former WAAF (Women's Auxiliary Air Force) Gwen Watkins brings to life the reality of the German Air Section. Her memoir is the first account of this crucial division. In a highly informative, lyrical account, she details her eventful interview, eventual appointment at the µthe biggest lunatic asylum in Britain', methods for cracking codes, the day-to-day routine and decommisioning of her section. Lord Asa Briggs is a renowned historian who also served at Bletchley Park.
