The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. 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 this World War II military history, Rommel's army is a day from Cairo, a week from Tel Aviv, and the SS is ready for action. Espionage brought the Nazis this far, but espionage can stop them—if Washington wakes up to the danger. As World War II raged in North Africa, General Erwin Rommel was guided by an uncanny sense of his enemies' plans and weaknesses. In the summer of 1942, he led his Axis army swiftly and terrifyingly toward Alexandria, with the goal of overrunning the entire Middle East. Each step was informed by detailed updates on British positions. The Nazis, somehow, had a source for the Allies' greatest secrets. Yet the Axis powers were not the only ones with intelligence. Brilliant Allied cryptographers worked relentlessly at Bletchley Park, breaking down the extraordinarily complex Nazi code Enigma. From decoded German messages, they discovered that the enemy had a wealth of inside information. On the brink of disaster, a fevered and high-stakes search for the source began. War of Shadows is the cinematic story of the race for information in the North African theater of World War II, set against intrigues that spanned the Middle East. Years in the making, this book is a feat of historical research and storytelling, and a rethinking of the popular narrative of the war. It portrays the conflict not as an inevitable clash of heroes and villains but a spiraling series of failures, accidents, and desperate triumphs that decided the fate of the Middle East and quite possibly the outcome of the war.

With exclusive interviews, a Signal Corps veteran tells the full story of how cryptography helped defeat the Axis powers, at Bletchley Park and beyond. For years, the story of the World War II codebreakers was kept a crucial state secret. Even Winston Churchill, himself a great advocate of Britain’s cryptologic program, purposefully minimized their achievements in his history books. Now, though, after decades have passed, the true scope of the British and American cryptographers’ role in the war has come to light. It was a role key to the Allied victory. From the Battle of Britain to the Pacific front to the panzer divisions in Africa, superior cryptography gave the Allies a decisive advantage over the Axis generals. Military intelligence made a significant difference in battle after battle. In Codebreakers’ Victory, veteran cryptographer Hervie Haufler takes readers behind the scenes in this fascinating underground world of ciphers and decoders. This broad view represents the first comprehensive account of codebreaking during World War II. Haufler pulls together years of research, exclusive access to top secret files, and personal interviews to craft a captivating must-read for anyone interested in the behind-the-front intellect and perseverance that went into beating the Nazis and Japan.

The dramatic, untold story of the brilliant team whose feats of innovation and engineering created the world’s first digital electronic computer—decrypting the Nazis’ toughest code, helping bring an end to WWII, and ushering in the information age. • Winner, Institute of Electrical and Electronics Engineers Middleton Award for "a book ... that both exemplifies exceptional scholarship and reaches beyond academic communities toward a broad public audience." • A Kirkus Best Book of 2022 • Planning the invasion of Normandy, the Allies knew that decoding the communications of the Nazi high command was imperative for its success. But standing in their way was an encryption machine they called Tunny (British English for “tuna”), which was vastly more difficult to crack than the infamous Enigma cipher. To surmount this seemingly impossible challenge, Alan Turing, the Enigma codebreaker, brought in a maverick English working-class engineer named Tommy Flowers who devised the ingenious, daring, and controversial plan to build a machine that would calculate at breathtaking speed and break the code in nearly real time. Together with the pioneering mathematician Max Newman, Flowers and his team produced—against the odds, the clock, and a resistant leadership—Colossus, the world’s first digital electronic computer, the machine that would help bring the war to an end. Drawing upon recently declassified sources, David A. Price’s Geniuses at War tells, for the first time, the full mesmerizing story of the great minds behind Colossus and chronicles the remarkable feats of engineering genius that marked the dawn of the digital age.

"While battalions hunkered down in the mud of western France, anti-aircraft guns took aim at zeppelins floating over the capital, and Atlantic convoys tried desperately to evade German U-boats, another, more secret battle was underway. Down gloomy Whitehall corridors a team of eccentric and pioneering codebreakers were fighting for information that would give them a decisive advantage over the enemy. The new technologies of wireless and telegraph were vital for governments and the military, but vulnerable to interception. Cracking the codes used to protect them quickly became a crucial part of the war effort, and London Room 40, led by the charismatic and cunning Blinker' Hall, was at the centre of this push for intelligence. Not content to wait for enemy communications to come to him, Hall was soon running agents in other countries, particularly in neutral USA where German saboteurs were intent on damaging the essential flow of munitions to Britain. The stories of Bletchley Park and the spies of the Second World War are well known, but it was Room 40 and their colleagues across the intelligence services that started it all. From the docks of New York City to shady Cairo hotels, this is the gripping and fast-paced story of spies, codebreakers and saboteurs."

An inspiring true story, perfect for fans of Hidden Figures, about an American woman who pioneered codebreaking in WWI and WWII but was only recently recognized for her extraordinary contributions. A YALSA EXCELLENCE IN NONFICTION FINALIST • A KIRKUS BEST BOOK OF THE YEAR Elizebeth Smith Friedman had a rare talent for spotting patterns and solving puzzles. These skills led her to become one of the top cryptanalysts in America during both World War I and World War II. She originally came to code breaking through her love for Shakespeare when she was hired by an eccentric millionaire to prove that Shakespeare's plays had secret messages in them. Within a year, she had learned so much about code breaking that she was a star in the making. She went on to play a major role decoding messages during WWI and WWII and also for the Coast Guard's war against smugglers. Elizebeth and her husband, William, became the top code-breaking team in the US, and she did it all at a time when most women weren't welcome in the workforce. Amy Butler Greenfield is an award-winning historian and novelist who aims to shed light on this female pioneer of the STEM community.
