This country house was home to Britain's most brilliant mathematical brains, like Alan Turing, and the scene of immense advances in technology—indeed, the birth of modern computing. The military codes deciphered there were instrumental in turning both the Battle of the Atlantic and the war in North Africa. But, though plenty has been written about the scientists and the codebreaking, fictional and non-fiction—from Robert Harris and Ian McEwan to Andrew Hodges' biography of Turing—what of the thousands of men and women who lived and worked there during the war? The first history for the general reader of life at Bletchley Park, this is also an amazing compendium of memories from people now in their eighties of skating on the frozen lake in the grounds (a depressed Angus Wilson, the novelist, once threw himself in), of a youthful Roy Jenkins—useless at codebreaking, of the high jinks at nearby accommodation hostels, and of the implacable secrecy that meant girlfriend and boyfriend working in adjacent huts knew nothing about each other's work.

    He was twenty-two. Soon recognized as a cryptographer of genius, he became head of communications at the Special Operations Executive (SOE), where he revolutionized the codemaking techniques of the Allies and trained some of the most famous agents dropped into occupied Europe, including "the White Rabbit" and Violette Szabo. As a top codemaker, Marks had a unique perspective on one of the most fascinating and, until now, little-known aspects of the Second World War. Writing with the narrative flair and vivid characterization of his famous screenplays, Marks gives free rein to his keen sense of the absurd and his wry wit, resulting in a thrilling and poignant memoir that celebrates individual courage and endeavor, without losing sight of the human cost and horror of war.

    Operation Fortitude, which protected and enabled the invasion, and the Double Cross system, which specialized in turning German spies into double agents, deceived the Nazis into believing that the Allies would attack at Calais and Norway rather than Normandy. It was the most sophisticated and successful deception operation ever carried out, ensuring that Hitler kept an entire army awaiting a fake invasion, saving thousands of lives, and securing an Allied victory at the most critical juncture in the war.   The story of D-Day has been told from the point of view of the soldiers who fought in it, the tacticians who planned it, and the generals who led it. But this epic event in world history has never before been told from the perspectives of the key individuals in the Double Cross System. These include its director (a brilliant, urbane intelligence officer), a colorful assortment of MI5 handlers (as well as their counterparts in Nazi intelligence), and the five spies who formed Double Cross’s nucleus: a dashing  Serbian playboy, a Polish fighter-pilot, a bisexual Peruvian party girl, a deeply eccentric Spaniard with a diploma in chicken farming and a volatile Frenchwoman, whose obsessive love for her pet dog very nearly wrecked the entire plan. The D-Day spies were, without question, one of the oddest military units ever assembled, and their success depended on the delicate, dubious relationship between spy and spymaster, both German and British. Their enterprise was saved from catastrophe by a shadowy sixth spy whose heroic sacrifice is revealed here for the first time.   With the same depth of research, eye for the absurd and masterful storytelling that have made Ben Macintyre an international bestseller,  Double Cross is a captivating narrative of the spies who wove a web so intricate it ensnared Hitler’s army and carried thousands of D-Day troops across the Channel in safety.

    Almost to the end of the war, the Germans had firm faith in the Enigma ciphering machine, but in fact the codebreakers were deciphering nearly 4,000 German transmissions daily by 1942, reaping a wealth of information on such important matters as the effort to resupply Rommel's army in North Africa and the effect of Allied attempts to mislead the Germans about the location of D-Day landings. Indeed, Winston Churchill hailed the work of Bletchley Park as the secret weapon that won the war. Only now, nearly half a century since the end of the Second World War, have any of the men and women in this group come forward to tell this remarkable story in their own words--a story that an oath of secrecy long prevented them from revealing. In Codebreakers, F.H. Hinsley and Alan Stripp have gathered together twenty-seven first-hand accounts of one of the most amazing feats in intelligence history. These engaging memoirs, each written by a different member of the codebreakers team, recount the long hours working in total secrecy and the feelings of camaraderie, tension, excitement, and frustration as these men and women, both British and American, did some of the most important work of the war. These talented people share not only their technical knowledge of cryptography and military logistics, but also poignant personal recollections as well. Walter Eytan, one of a handful of Jews at Betchley Park, recalls intercepting a message from a German vessel which reported that it carried Jews en route for Piraeus zur Endlosung (for the final solution). Eytan writes I had never heard this expression before, but instinctively, I knew what it must mean, and I have never forgotten that moment. Vivienne Alford tells of her chilling memory of hearing that the atomic bomb had been dropped on Hiroshima, and the stillness that came over her and her co-workers in Naval Section VI. And William Millward confides that he is still haunted by the work he did in Hut 3 nearly fifty years ago. I sometimes wonder, especially during the night, how many sailors I drowned. Few readers will finish this book without feeling that the codebreakers were essential to the outcome of the war--and thereby of major importance in helping to shape the world we live in today.

    Using science, math, innovation, and improvisation, Bletchley Park code breakers worked furiously to invent a machine to decipher what turned out to be the secrets of Nazi high command. It was called Colossus. What these code breakers didn't realize was that they had fashioned the world's first true computer. When the war ended, this incredible invention was dismantled and hidden away for almost 50 years. Paul Gannon has pieced together the tremendous story of what is now recognized as the greatest secret of Bletchley Park.

    Sebag-Montefiore also relates new details about the genesis of the code, little-known facts about how the Poles first cracked the Luftwaffe's version of the code (and then passed it along to the British), and the feverish activities at Bletchley Park. Based in part on documents recently unearthed from American and British archives--including previously confidential government files--and in part on unforgettable, firsthand accounts of surviving witnesses, Enigma unearths the stunning truth about the brilliant piece of decryption that changed history.

    The guerrilla campaign that followed was every bit as extraordinary as the six men who directed it. One of them, Cecil Clarke, was a maverick engineer who had spent the 1930s inventing futuristic caravans. Now, his talents were put to more devious use: he built the dirty bomb used to assassinate Hitler's favorite, Reinhard Heydrich. Another, William Fairbairn, was a portly pensioner with an unusual passion: he was the world's leading expert in silent killing, hired to train the guerrillas being parachuted behind enemy lines. Led by dapper Scotsman Colin Gubbins, these men—along with three others—formed a secret inner circle that, aided by a group of formidable ladies, single-handedly changed the course Second World War: a cohort hand-picked by Winston Churchill, whom he called his Ministry of Ungentlemanly Warfare.Giles Milton's Churchill's Ministry of Ungentlemanly Warfare is a gripping and vivid narrative of adventure and derring-do that is also, perhaps, the last great untold story of the Second World War.

    His breaking of the German U-boat Enigma cipher in World War II ensured Allied-American control of the Atlantic. But Turing's vision went far beyond the desperate wartime struggle. Already in the 1930s he had defined the concept of the universal machine, which underpins the computer revolution. In 1945 he was a pioneer of electronic computer design. But Turing's true goal was the scientific understanding of the mind, brought out in the drama and wit of the famous "Turing test" for machine intelligence and in his prophecy for the twenty-first century.Drawn in to the cockpit of world events and the forefront of technological innovation, Alan Turing was also an innocent and unpretentious gay man trying to live in a society that criminalized him. In 1952 he revealed his homosexuality and was forced to participate in a humiliating treatment program, and was ever after regarded as a security risk. His suicide in 1954 remains one of the many enigmas in an astonishing life story.

    Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

    In 1942, the Allies were losing, Germany seemed unstoppable, and every able man in England was fighting. Churchill believed Britain was locked in an existential battle and created a secret agency, the Special Operations Executive (SOE), whose spies were trained in everything from demolition to sharp-shooting. Their job, he declared, was "to set Europe ablaze!" But with most men on the frontlines, the SOE did something unprecedented: it recruited women. Thirty-nine women answered the call, leaving their lives and families to become saboteurs in France. Half were caught, and a third did not make it home alive. In D-Day Girls, Sarah Rose draws on recently declassified files, diaries, and oral histories to tell the story of three of these women. There's Odette Sansom, a young mother who feels suffocated by domestic life and sees the war as her ticket out; Lise de Baissac, an unflappable aristocrat with the mind of a natural leader; and Andrée Borrel, the streetwise organizer of the Paris Resistance. Together, they derailed trains, blew up weapons caches, destroyed power and phone lines, and gathered crucial intelligence—laying the groundwork for the D-Day invasion that proved to be the turning point in the war. Stylishly written and rigorously researched, this is an inspiring story for our own moment of resistance, in which women continue to play a vital role.

    Army and Navy and the British government over the last five years. Now, Battle of Wits presents the history of the war that these documents reveal. From the battle of Midway until the last German code was broken in January 1945, this is an astonishing epic of a war that was won not simply by brute strength but also by reading the enemy's intentions. The revelations of Stephen Budiansky's dramatic history include how Britain tried to manipulate the American codebreakers and monopolize German Enigma code communications; the first detailed published explanations of how the Japanese codes were broken; and how the American codebreaking machines worked to crack the Japanese, the German, and even the Russian diplomatic codes. The compelling narrative shows the crucial effect codebreaking had on the battlefields by explaining the urgency of stopping the wolf pack U-boat attacks in the North Atlantic, the importance of halting Rommel's tanks in North Africa, and the necessity of ensuring that the Germans believed the Allies' audacious deception and cover plans for D-Day. Unveiled for the first time, the complete story of codebreaking in World War II has now been told.

    Many were just school girls at the outbreak of war; the next six years would change their lives forever. This vivid portrayal of their experiences, sacrifices, and memories is a poignant reminder that without the work of thousands of young women Bletchley Park's extraordinary achievements would not have been possible. By meeting and talking to these fascinating female secret-keepers who are still alive today, Tessa Dunlop captures their extraordinary journeys into an adult world of war, secrecy, love, and loss. Through the voices of the women themselves, this is the story of life at Bletchley Park beyond the celebrated code-breakers; it's the story of the girls behind Britain's ability to consistently outsmart the enemy.

    The Fuehrer had begun cataloguing the art he planned to collect as well as the art he would destroy: "degenerate" works he despised.In a race against time, behind enemy lines, often unarmed, a special force of American and British museum directors, curators, art historians, and others, called the Momuments Men, risked their lives scouring Europe to prevent the destruction of thousands of years of culture.Focusing on the eleven-month period between D-Day and V-E Day, this fascinating account follows six Monuments Men and their impossible mission to save the world's great art from the Nazis.

    This book reveals how author Roald Dahl was a member of Churchill's infamous dirty tricks squad.

    Half a century of murderous oppression of scores of millions under the iron boot of Communist tyranny might never have happened, and Europe’s central role in world affairs might have been sustained for many generations.Among the British and Churchillian blunders were:• The secret decision of a tiny cabal in the inner Cabinet in 1906 to take Britain straight to war against Germany, should she invade France• The vengeful Treaty of Versailles that mutilated Germany, leaving her bitter, betrayed, and receptive to the appeal of Adolf Hitler• Britain’s capitulation, at Churchill’s urging, to American pressure to sever the Anglo-Japanese alliance, insulting and isolating Japan, pushing her onto the path of militarism and conquest• The 1935 sanctions that drove Italy straight into the Axis with Hitler• The greatest blunder in British history: the unsolicited war guarantee to Poland of March 1939—that guaranteed the Second World War• Churchill’s astonishing blindness to Stalin’s true ambitions. Certain to create controversy and spirited argument, Churchill, Hitler, and “The Unnecessary War” is a grand and bold insight into the historic failures of judgment that ended centuries of European rule and guaranteed a future no one who lived in that vanished world could ever have envisioned.From the Hardcover edition.
