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.

    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.

    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.

    Moving chronologically through the conflict, Max Hastings charts the successes and failures of allied and axis forces, espionage and counterespionage.Observing how the evolution of electronic communications dramatically increased the possibilities and significance of these secret battles, this is the story of intelligence beyond Bletchley to the FBI, Russia and the spies of axis dictatorships. For the first time since his best-selling ‘All Hell Let Loose’, Max Hastings returns to the Second World War, this time to chronicle its second, untold story.

    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.

    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.

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

    This was to be 'Station X', the Allies' top-secret centre for deciphering enemy codes.Their task was to break the ingenious Enigma cypher 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 generals.'Sation X' is also the story of the people involved from leading codebreakers such as Alan Turing, father of the modern computer, to the female operators who intercepted the messages. Through interviews with surviving members of Bletchley Park, Michael Smith has discovered what life was like there. In this chaotic and isolated environment they found time for drama performances, music recitals, orchestras and love affairs.Not only did these people shorten the war by several years - they were essential to victory in the Atlantic and North Africa and to the masterminding of the D-Day landings - 'Station X' was also the birth place of the world's first programmable computer and the successful Anglo-American intelligence partnership.

    They have the physicists. They have the will. What they don’t have is enough “heavy water," an essential ingredient for their nuclear designs. For two years, the Nazis have occupied Norway, and with it the Vemork hydroelectric plant, a massive industrial complex nestled on a precipice of a gorge. Vemork is the world’s sole supplier of heavy water, and under the threat of death, its engineers pushed production into overtime. For the Allies, Vemork must be destroyed. But how would they reach the castle fortress high in a mountainous valley? The answer became the most dramatic commando raid of the war. The British Special Operations Executive together a brilliant scientist and eleven refugee Norwegian commandos, who, with little more than parachutes, skis, and Tommy Guns, would destroy Hitler’s nuclear ambitions and help end the reign of the Third Reich. Based on exhaustive research and never-before-seen diaries and letters of the saboteurs, The Winter Fortress is a compulsively readable narrative about a group of young men who endured soul-crushing setbacks and Gestapo hunts and survived in one of the coldest, most inhospitable places on earth to save the world from destruction.

    As an agent for Britain’s MI-6 and then America’s OSS during World War II, these qualities proved crucial to her success. This is the remarkable story of this “Mata Hari from Minnesota” (Time) and the passions that ruled her tempestuous life—a life filled with dangerous liaisons and death-defying missions vital to the Allied victory.For decades, much of Betty’s career working for MI-6 and the OSS remained classified. Through access to recently unclassified files, Howard Blum discovers the truth about the attractive blond, codenamed “Cynthia,” who seduced diplomats and military attachés across the globe in exchange for ciphers and secrets; cracked embassy safes to steal codes; and obtained the Polish notebooks that proved key to Alan Turing’s success with Operation Ultra.Beneath Betty’s cool, professional determination, Blum reveals a troubled woman conflicted by the very traits that made her successful: her lack of deep emotional connections and her readiness to risk everything. The Last Goodnight is a mesmerizing, provocative, and moving portrait of an exceptional heroine whose undaunted courage helped to save the world.

    Hemmed in by overwhelming Nazi strength, the 338,000 men gathered on the beach were all that stood between Hitler and Western Europe. Crush them, and the path to Paris and London was clear.Unable to retreat any farther, the Allied soldiers set up defense positions and prayed for deliverance. Prime Minister Winston Churchill ordered an evacuation on May 26, expecting to save no more than a handful of his men. But Britain would not let its soldiers down. Hundreds of fishing boats, pleasure yachts, and commercial vessels streamed into the Channel to back up the Royal Navy, and in a week nearly the entire army was ferried safely back to England.Based on interviews with hundreds of survivors and told by “a master narrator,” The Miracle of Dunkirk is a striking history of a week when the outcome of World War II hung in the balance (Arthur Schlesinger Jr.).

    NBC News calls it, "A historical document of major significance." The focus is on Sir William Stephenson, Britain's urbane spy chief who inspired James Bond.

    The Turn of the Tide is a fascinating nuts-and-bolts account of the strategic factors that led to Allied victory. Kennedy reveals how the leaders’ grand strategy was carried out by the ordinary soldiers, scientists, engineers, and businessmen responsible for realizing their commanders’ visions of success.In January 1943, FDR and Churchill convened in Casablanca and established the Allied objectives for the war: to defeat the Nazi blitzkrieg; to control the Atlantic sea lanes and the air over western and central Europe; to take the fight to the European mainland; and to end Japan’s imperialism. Astonishingly, a little over a year later, these ambitious goals had nearly all been accomplished. With riveting, tactical detail, The Turn of the Tide reveals how.Kennedy recounts the inside stories of the invention of the cavity magnetron, a miniature radar “as small as a soup plate,” and the Hedgehog, a multi-headed grenade launcher that allowed the Allies to overcome the threat to their convoys crossing the Atlantic; the critical decision by engineers to install a super-charged Rolls-Royce engine in the P-51 Mustang, creating a fighter plane more powerful than the Luftwaffe’s; and the innovative use of pontoon bridges (made from rafts strung together) to help Russian troops cross rivers and elude the Nazi blitzkrieg. He takes readers behind the scenes, unveiling exactly how thousands of individual Allied planes and fighting ships were choreographed to collectively pull off the invasion of Normandy, and illuminating how crew chiefs perfected the high-flying and inaccessible B-29 Superfortress that would drop the atomic bombs on Japan.The story of World War II is often told as a grand narrative, as if it were fought by supermen or decided by fate. Here Kennedy uncovers the real heroes of the war, highlighting for the first time the creative strategies, tactics, and organizational decisions that made the lofty Allied objectives into a successful reality. In an even more significant way, The Turn of the Tide has another claim to our attention, for it restores “the middle level of war” to its rightful place in history.From the Hardcover edition.

    They had refused or been unable to leave for many different reasons; their actions during the course of the German occupation would prove to be just as varied. Glass interweaves the experiences of some of the individuals who belonged to this unique colony of American expatriates living in Paris. Among the stories highlighted are those of Charles Bedaux, an American millionaire determined to carry on with his business affairs as usual; Sylvia Beach, owner of the famous English-language bookstore Shakespeare & Company; Clara Longworth de Chambrun, patroness of the American Library in Paris and distantly related to FDR; and Dr. Sumner Jackson, the American Hospital’s chief surgeon. These fascinating tales reflect the complicated network of choices—passive compromise, outright collaboration, patient retreat, and active resistance—that existed for Americans caught in the German web.

    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.
