From the Purple Machine to the Navajo Talkers to the breaking of Japan's JN-25 Naval Code to the shadowy world of decoding units like Hut-8 in Bletchley Park, he shows how crucial information-often obtained by surreptitious and violent means-was the decisive edge in the Battle of Britain, at Midway and against the U-Boats in the North Atlantic, and how Allied intelligence saved the Soviet Union from almost certain defeat. In an accessible account based on years of research, interviews and exclusive access to previously top-secret archives, Haufler demonstrates how cryptography enabled Nimitz and MacArthur to persevere in the Pacific and helped Eisenhower and Patton mount the assaults on Normandy. In compelling detail, Haufler shows us how it was done-as only one who was on the frontlines of the "secret war" could tell it.

    F.W. Winterbotham, was the man responsible for the organization, distribution & security of Ultra. This is his personal account of the operation.

    The tycoon had close ties to the U.S. government, and he soon asked Elizebeth to apply her language skills to an exciting new venture: code-breaking. There she met the man who would become her husband, groundbreaking cryptologist William Friedman. In The Woman Who Smashed Codes, Jason Fagone chronicles the life of Elizebeth Smith who played an integral role in our nation's history for forty years. After World War I, Smith used her talents to catch gangsters and smugglers during Prohibition, then accepted a covert mission to discover and expose Nazi spy rings that were spreading like wildfire across South America, advancing ever closer to the United States. As World War II raged, Elizebeth fought a highly classified battle of wits against Hitler's Reich, cracking multiple versions of the Enigma machine used by German spies. Meanwhile, inside an Army vault in Washington, William worked furiously to break Purple, the Japanese version of Enigma--and eventually succeeded, at a terrible cost to his personal life.Fagone unveils America's code-breaking history through the prism of Smith's life, bringing into focus the unforgettable events and colorful personalities that would help shape modern intelligence.

    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.

    Britain's Secret Intelligence Service (MI6) was born a century ago amid fears of the rising power of other countries, especially Germany. The next 40 years saw MI6 taking an increasingly important & largely hidden role in shaping history. This revelatory account draws on a wealth of archival materials never before seen by outsiders to unveil the inner workings of the world's 1st spy agency. MI6's early days were haphazard but it was quickly forged into an effective organization during WWI. During the war years, MI6 also formed ties with the USA--harbingers of a relationship that would become vital to both. These early years also saw the development of techniques that would become plot devices in books & films--forgery, invisible ink, disguises, concealing mechanisms etc. The interwar years were nominally peaceful, but Britain perceived numerous threats, all of which MI6 was expected to keep tabs on. The outbreak of WWII again caught MI6 off balance, & high-profile blunders (& the memoirs of MI6 operatives like Graham Greene) created an impression of ineffectiveness. At the same time the service was pioneering cryptography at Bletchley Park, breaking the Enigma code & devising the methods & equipment inspiring Ian Fleming's novels. The aftermath of WWII was as dramatic as the war itself had been, because 1945-49 saw not only the end of the British Empire but also the emergence of a new sort of conflict--the Cold War. We witness MI6 wrestling with these epic changes as it tightens its bonds with the newly christened CIA, changes that would dictate the shape of the service & the world for decades.

    19 specially adapted Lancasters take off from RAF Scampton, each with a huge 9,000 lb cylindrical bomb strapped underneath them. Their mission: to destroy three dams deep within the German heartland, which provide the lifeblood to the industries supplying the Third Reich's war machine.

    A few weeks later a mathematician in Warsaw begins to decipher the coded communications of the Third Reich and lay the foundations for the code-breaking operation at Bletchley Park. The co-operation between France, Britain and Poland is given the cover name ‘X, Y & Z’. December, 1942: It is the middle of World War II. The Polish code-breakers are in France on the run from the Gestapo. People who know the Enigma secret are not supposed to be in the combat zone for fear of capture so MI6 devises a plan to exfiltrate them. If it goes wrong, if they are caught, they could give away the greatest secret of the war. X, Y & Z describes how French, British and Polish secret services came together to unravel the Enigma machine. It tells of how, under the very noses of the Germans, Enigma code-breaking continued in Vichy France. And how code-breakers from Poland continued their work for Her Majesty’s Secret Service, watching the USSR’s first steps of the Cold War. The people of X, Y and Z were eccentric, colorful and caught up in world events that they could watch not control. This is their story…

    The book reveals the precise role of the Security Service in twentieth-century British history, from its foundation by Captain Kell of the British Army in October 1909, through two world wars, up to and including its present roles in counterespionage and counterterrorism. The book describes how MI5 has been managed, what its relationship has been with government, where it has triumphed, and where it has failed. In all of this no restriction has been placed on the judgments made by the author. "Defend the Realm "also adds significantly to our knowledge of many celebrated events and notorious individuals and definitively lays to rest a number of persistent myths.""Above all, it shows the place of this previously extremely secretive organization within the United Kingdom. Few books could make such an immediate and extraordinary increase to our understanding of British history over the past century.

    government faced many difficult decisions, including what to do with the Third Reich’s scientific minds. These were the brains behind the Nazis’ once-indomitable war machine. So began Operation Paperclip, a decades-long, covert project to bring Hitler’s scientists and their families to the United States.Many of these men were accused of war crimes, and others had stood trial at Nuremberg; one was convicted of mass murder and slavery. They were also directly responsible for major advances in rocketry, medical treatments, and the U.S. space program. Was Operation Paperclip a moral outrage, or did it help America win the Cold War?Drawing on exclusive interviews with dozens of Paperclip family members, colleagues, and interrogators, and with access to German archival documents (including previously unseen papers made available by direct descendants of the Third Reich’s ranking members), files obtained through the Freedom of Information Act, and dossiers discovered in government archives and at Harvard University, Annie Jacobsen follows more than a dozen German scientists through their postwar lives and into a startling, complex, nefarious, and jealously guarded government secret of the twentieth century.In this definitive, controversial look at one of America’s most strategic, and disturbing, government programs, Jacobsen shows just how dark government can get in the name of national security.

    Then, attempting to break a Nazi code during World War II, he successfully designed and built one, thus ensuring the Allied victory. Turing became a champion of artificial intelligence, but his work was cut short. As an openly gay man at a time when homosexuality was illegal in England, he was convicted and forced to undergo a humiliating "treatment" that may have led to his suicide.With a novelist's sensitivity, David Leavitt portrays Turing in all his humanity—his eccentricities, his brilliance, his fatal candor—and elegantly explains his work and its implications.

    McManus has written a gripping history that will stand as the last word on this titanic battle. Nicknamed the Big Red One, 1st Division had fought from North Africa to Sicily, earning a reputation as stalwart warriors on the front lines and rabble-rousers in the rear. Yet on D-Day, these jaded combat veterans melded with fresh-faced replacements to accomplish one of the most challenging and deadly missions ever. As the men hit the beach, their equipment destroyed or washed away, soldiers cut down by the dozens, courageous heroes emerged: men such as Sergeant Raymond Strojny, who grabbed a bazooka and engaged in a death duel with a fortified German antitank gun; T/5 Joe Pinder, a former minor-league pitcher who braved enemy fire to save a vital radio; Lieutenant John Spalding, a former sportswriter, and Sergeant Phil Streczyk, a truck driver, who together demolished a German strong point overlooking Easy Red, where hundreds of Americans had landed.Along the way, McManus explores the Gap Assault Team engineers who dealt with the extensive mines and obstacles, suffering nearly a fifty percent casualty rate; highlights officers such as Brigadier General Willard Wyman and Colonel George Taylor, who led the way to victory; and punctures scores of myths surrounding this long-misunderstood battle.The Dead and Those About to Die draws on a rich array of new or recently unearthed sources, including interviews with veterans. The result is history at its finest, the unforgettable story of the Big Red One’s nineteen hours of hell—and their ultimate triumph—on June 6, 1944.INCLUDES PHOTOGRAPHS

    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.

    Turing’s openness about his homosexuality at a time when it was an imprisonable offense ultimately led to his untimely lo death at the age of only forty-one. In Alan Turing: Unlocking the Enigma, David Boyle reveals the mysteries behind the man and his remarkable career. Aged just 22, Turing was elected a fellow at King's College, Cambridge on the strength of a dissertation in which he proved the central limit theorem. By the age of 33, he had been awarded the OBE by King George VI for his wartime services: Turing was instrumental in cracking the Nazi Enigma machines at the top secret code breaking establishment at Bletchley Park during the Second World War.But his achievements were to be tragically overshadowed by the paranoia of the post-War years. Hounded for his supposedly subversive views and for his sexuality, Turing was prosecuted in 1952, and forced to accept the humiliation of hormone treatment to avoid a prison sentence. Just two years later, at the age of 41 he was dead. The verdict: cyanide poisoning.Was Turing’s death accidental as his mother always claimed? Or did persistent persecution drive him to take him own life?Alan Turing: Unlocking the Enigma seeks to find the man behind the science, illuminating the life of a person who is still a shadowy presence behind his brilliant achievements.

    But how did young Winston become Churchill? What gave him the strength to take on the superior force of Nazi Germany when bombs rained on London and so many others had caved? In The Storm of War, Andrew Roberts gave us a tantalizing glimpse of Churchill the war leader. Now, at last, we have the full and definitive biography, as personally revealing as it is compulsively readable, about one of the great leaders of all time.Roberts was granted exclusive access to extensive new material: the transcripts of war cabinet meetings - the equivalent of the Nixon and JFK tapes - diaries, letters, unpublished memoirs, and detailed notes taken by the king after their bi-weekly meetings. Having read every one of Churchill's letters, including deeply personal ones that Churchill's son Randolph had previously chosen to withhold, and spoken to more than one hundred people who knew or worked with him, Roberts identifies the hidden forces fueling Churchill's drive. Churchill put his faith in the British Empire and fought as hard to preserve it as he did to defend London. Having started his career in India and South Africa, he understood better than most idealists how hard it can be to pacify reluctant people far from home.We think of Churchill as a hero of the age of mechanized warfare, but Roberts's masterwork reveals that he has as much to teach us about the challenges we face today and the fundamental values of courage, tenacity, leadership, and moral conviction.

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