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.

The extraordinary story of a headmaster turned cryptographer, and our top-secret war with the Kaiser's Reich. On 11 August 1914, just days after war had been declared, Australian Captain J.T. Richardson boarded a German merchant vessel fleeing Melbourne's Port Phillip and audaciously seized a top-secret naval codebook. The fledgling Australian Navy had an opportunity to immediately change the course of the war. But what exactly had they found? Enter the Australian code breakers ... Recruited by savvy top brass, maths whizz and German speaker Frederick Wheatley worked night and day to fathom the basic principles of the code and start tracking the German Navy's powerful East Asia Squadron, led by the brilliant Maximilian von Spee. Soon Melbourne was a hub of international Allied intelligence. This is the untold story of how a former Australian headmaster and his mostly female team cracked one of Germany's most complex codes, paving the way for the greatest Allied naval victory of World War I.

The complete story of how the German Enigma codes were broken. Perfect for fans of THE IMITATION GAME, the new film on Alan Turing's Enigma code, starring Benedict Cumberbatch. Breaking the German Enigma codes was not only about brilliant mathematicians and professors at Bletchley Park. There is another aspect of the story which it is only now possible to tell. It takes in the exploits of spies, naval officers and ordinary British seamen who risked, and in some cases lost, their lives snatching the vital Enigma codebooks from under the noses of Nazi officials and from sinking German ships and submarines. This book tells the whole Enigma story: its original invention and use by German forces and how it was the Poles who first cracked - and passed on to the British - the key to the German airforce Enigma. The more complicated German Navy Enigma appeared to them to be unbreakable.

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.

“An absorbing and thoroughly well documented account” of WWII naval intelligence and the Allied hunt for the Nazi code machine known as the Enigma (Warship). From the start of World War II to mid-1943, British and American naval forces fought a desperate battle against German submarine wolfpacks. And the Allies might have lost the struggle at sea without an astounding intelligence coup. Here, the author brings to life the race to break the German U-boat codes. As the Battle of the Atlantic raged, Hitler’s U-boats reigned. To combat the growing crisis, ingenious amateurs joined the nucleus of dedicated professionals at Bletchley Park to unlock the continually changing German naval codes. Their mission: to read the U-boat messages of Hitler’s cipher device, the Enigma. They first found success with the capture of U-110,—which yielded the Enigma machine itself and a trove of secret documents. Then the weather ship Lauenburg seized near the Arctic ice pack provided code settings for an entire month. Finally, two sailors rescued a German weather cipher that enabled the team at Bletchley to solve the Enigma after a year-long blackout. In “a highly recommended account with a wealth of materials” Seizing the Enigma tells the story of a determined corps of people who helped turn the tide of the war (Naval Historical Foundation).

The story of Bletchley Park's codebreaking operations in the Second World War is now well known, but its counterparts in the First World War – Room 40 & MI1(b) – remain in the shadows, despite their involvement in and influence on most of the major events of that war. From the First Battle of the Marne, the shelling of Scarborough, the battles of Jutland and the Somme in 1916, to the battles on the Western Front in 1918, the German naval mutiny and the Zimmermann Telegram, this cast of characters – several of them as eccentric as anyone from Bletchley Park in the Second World War – secretly guided the outcome of the 'Great War' from the confines of a few smoke-filled rooms. Using hundreds of intercepted and decrypted German military, naval and diplomatic messages, bestselling author Paul Gannon reveals the fascinating story of British codebreaking operations. By drawing on many newly discovered archival documents that challenge misleading stories about Room 40 & MI1(b), he reveals a sophisticated machine in operation.
