Book Description
“A tremendous tale of hushed and unhushed uproars in the linked fields of war and diplomacy” (The New York Times), from the Pulitzer Prize–winning author of The Guns of August In January 1917, the war in Europe was, at best, a tragic standoff. Britain knew that all was lost unless the United States joined the war, but President Wilson was unshakable in his neutrality. At just this moment, a crack team of British decoders in a quiet office known as Room 40 intercepted a document that would change history. The Zimmermann telegram was a top-secret message to the president of Mexico, inviting him to join Germany and Japan in an invasion of the United States. How Britain managed to inform the American government without revealing that the German codes had been broken makes for an incredible story of espionage and intrigue as only Barbara W. Tuchman could tell it. The Proud Tower, The Guns of August, and The Zimmermann Telegram comprise Barbara W. Tuchman’s classic histories of the First World War era.

Book Description
By the winter of 1916/17, World War I had reached a deadlock. While the Allies commanded greater resources and fielded more soldiers than the Central Powers, German armies had penetrated deep into Russia and France, and tenaciously held on to their conquered empire. Hoping to break the stalemate on the western front, the exhausted Allies sought to bring the neutral United States into the conflict. A golden opportunity to force American intervention seemed at hand when British naval intelligence intercepted a secret telegram detailing a German alliance offer to Mexico. In it, Berlin’s foreign secretary, Arthur Zimmermann, offered his country’s support to Mexico for re-conquering “the lost territory in Texas, New Mexico, and Arizona” in exchange for a Mexican attack on the United States, should the latter enter the war on the side of the Allies. The British handed a copy of the Telegram to the American government, which in turn leaked it to the press. On March 1, 1917, the Telegram made headline news across the United States, and five weeks later, America entered World War I. Based on an examination of virtually all available German, British, and U.S. government records, this book presents the definitive account of the Telegram and questions many traditional views on the origins, cryptanalysis, and impact of the German alliance scheme. While the Telegram has often been described as the final step in a carefully planned German strategy to gain a foothold in the western hemisphere, this book argues that the scheme was a spontaneous initiative by a minor German foreign office official, which gained traction only because of a lack of supervision and coordination at the top echelon of the German government. On the other hand, the book argues, American and British secret services had collaborated closely since 1915 to bring the United States into the war, and the Telegram’s interception and disclosure represented the crowning achievement of this clandestine Anglo-American intelligence alliance. Moreover, the book explicitly challenges the widely accepted notion that the Telegram’s publication in the U.S. press rallied Americans for war. Instead, it contends that the Telegram divided the public by poisoning the debate over intervention, and by failing to offer peace-minded Americans a convincing rationale for supporting the war. The book also examines the Telegram’s effect on the memory of World War I through the twentieth century and beyond.

Book Description
This accessible textbook presents a fascinating review of cryptography and cryptanalysis across history. The text relates the earliest use of the monoalphabetic cipher in the ancient world, the development of the “unbreakable” Vigenère cipher, and an account of how cryptology entered the arsenal of military intelligence during the American Revolutionary War. Moving on to the American Civil War, the book explains how the Union solved the Vigenère ciphers used by the Confederates, before investigating the development of cipher machines throughout World War I and II. This is then followed by an exploration of cryptology in the computer age, from public-key cryptography and web security, to criminal cyber-attacks and cyber-warfare. Looking to the future, the role of cryptography in the Internet of Things is also discussed, along with the potential impact of quantum computing. Topics and features: presents a history of cryptology from ancient Rome to the present day, with a focus on cryptology in the 20th and 21st centuries; reviews the different types of cryptographic algorithms used to create secret messages, and the various methods for breaking such secret messages; provides engaging examples throughout the book illustrating the use of cryptographic algorithms in different historical periods; describes the notable contributions to cryptology of Herbert Yardley, William and Elizebeth Smith Friedman, Lester Hill, Agnes Meyer Driscoll, and Claude Shannon; concludes with a review of tantalizing unsolved mysteries in cryptology, such as the Voynich Manuscript, the Beale Ciphers, and the Kryptos sculpture. This engaging work is ideal as both a primary text for courses on the history of cryptology, and as a supplementary text for advanced undergraduate courses on computer security. No prior background in mathematics is assumed, beyond what would be encountered in an introductory course on discrete mathematics.

Book Description
In May 1917, William and Elizebeth Friedman were asked by the U.S. Army to begin training officers in cryptanalysis and to decrypt intercepted German diplomatic and military communications. In June 1917, Herbert Yardley convinced the new head of the Army’s Military Intelligence Division to create a code and cipher section for the Army with himself as its head. These two seminal events were the beginning of modern American cryptology, the growth of which culminated 35 years later with the creation of the National Security Agency. Each running their own cryptologic agencies in the 1920s, the Friedman-Yardley relationship was shattered after Yardley published a tell-all book about his time in military intelligence. Yet in the end, the work they all started in 1917 led directly to the modern American intelligence community. As they got older, they became increasingly irrelevant in the burgeoning American cryptologic fraternity. Topics and features: * Examines the lives of three remarkable and pioneering cryptologists * Offers fascinating insights into spies, codes and ciphers, rumrunners, poker, and military history * Sheds new light on interesting parts of the cryptologists’ careers—especially Elizebeth Friedman, whose work during World War II has just begun to be explored * Recounts several good stories, i.e., What if the Friedmans had gone to work for Herbert Yardley in his new Cipher Bureau in 1919? What if Yardley had moved back to Washington to work for William Friedman a decade later? This enjoyable book has wide appeal for: general readers interested in the evolution of American cryptology, American historians (particularly of World War I, the inter-war period, and World War II signals intelligence), and historians of—and general readers interested in—American military intelligence. It also can be used as an auxiliary text or recommended reading in introductory or survey courses in history or on the related topics.

Book Description
Known as “the Great War,” the world’s first truly global conflict is remarkable in what might now be termed modern espionage. World War I was witness to plenty of ”firsts.” Apart from the contribution made by aerial reconnaissance and the interception of wireless telegraphy, telephone and cable traffic, there was the scientific aspect, with new machines of war, such as the submarine, sea-mine, torpedo, airship, barbed wire, armored tank and mechanized cavalry in a military environment that included mustard gas, static trench warfare, the indiscriminate bombardment of civilian population centers and air-raids. Large-scale sabotage and propaganda, the manipulation of news and of radio broadcasts, and censorship, were all features of a new method of engaging in combat, and some ingenious techniques were developed to exploit the movement of motor and rail transport, and the transmission of wireless signals. The hitherto unknown disciplines of train-watching, bridge-watching, airborne reconnaissance and radio interception would become established as routine collection methods, and their impact on the conflict would prove to be profound. The Historical Dictionary of World War I Intelligence relates this history through a chronology, an introductory essay, an appendix, and an extensive bibliography. The dictionary section has over 400 hundred cross-referenced entries on intelligence organizations, the spies, and the major cases and events of World War I. This book is an excellent access point for students, researchers, and anyone wanting to know more about the world of intelligence in World War I.
