Cryptologic Aspects of German Intelligence Activities in South America During World War II by David P. Mowry,Center for Cryptologic History,National Security Agency Pdf
This publication joins two cryptologic history monographs that were published separately in 1989. In part I, the author identifies and presents a thorough account of German intelligence organizations engaged in clandestine work in South America as well as a detailed report of the U.S. response to the perceived threat. Part II deals with the cryptographic systems used by the varioius German intelligence organizations engaged in clandestine activities.
Protesters called it an act of war when the U.S. Coast Guard sank a Canadian-flagged vessel in the Gulf of Mexico in 1929. It took a cool-headed codebreaker solving a “trunk-full” of smugglers’ encrypted messages to get Uncle Sam out of the mess: Elizebeth Smith Friedman’s groundbreaking work helped prove the boat was owned by American gangsters. This book traces the career of a legendary U.S. law enforcement agent, from her work for the Allies during World War I through Prohibition, when she faced danger from mobsters while testifying in high profile trials. Friedman founded the cryptanalysis unit that provided evidence against American rum runners and Chinese drug smugglers. During World War II, her decryptions brought a Japanese spy to justice and her Coast Guard unit solved the Enigma ciphers of German spies. Friedman’s “all source intelligence” model is still used by law enforcement and counterterrorism agencies against 21st century threats.

Nazi Intelligence Operations in Non-Occupied Territories by Christopher Vasey Pdf
Drawing heavily on recently declassified sources, this examination of German wartime intelligence services traces the logistical and strategic expansion of the Third Reich's foreign covert operations in World War II. Beginning with the changes introduced to counteract institutional neglect, the author describes attempts to penetrate both neutral and adversarial nations outside territories occupied by the Wehrmacht. The Nazis created covert teams for counterintelligence and penetrating border defenses. Strategies were formed for assembling saboteur divisions in North and South America, while data were gathered on industrial installations to target. American fascist movements of the 1930s are discussed, along with Nazi sabotage missions in the United States and intelligence penetrations and domestic collusion in Latin America.
History of Cryptography and Cryptanalysis by John F. Dooley Pdf
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.
The book takes place in the poorest country in South America. In fact, in considering the Western Hemisphere, it ranks next to last, with only Haiti being poorer, yet it is a country rich in national resources. The book covers one of the most tenuous times in Bolivian history. While it is the story of a missionary family, the book provides unusual insight to the rapid change occurring at so many levels in the country. The book points to the 1952 revolution as the starting point of a vastly significant process of social and political transformation that has bought Bolivia to its present status. Bolivia has a history of political change occurring not at the ballot box but most frequently by a military coup. The ’52 revolution was like the jump start to a battery which, in this case, triggered the political awakening of the majority of indigenous communities long held in a semifeudal condition. The book draws out the many external influences which played a role in defining the outcome of the transition. Bolivia’s natural resources were a tempting prize from the early colonial period when gold and silver were the attractions for Spain. During World War II, the metals tin, zinc, and tungsten were important to the United States. More recently, for the time period covered by the book, it was the petroleum and forest products. The external influences were more than economic. The book covered the range from former Nazis to Cuban communists. The thread running through the book is about the life of a missionary family. It is the story of a young couple with three children who left the comfort and security of the US Midwest farming communities to serve Christ as missionaries to Bolivia. However, the book does much more. It reveals how these Americans adjust into what is a semi-hostile environment struggling to cast off its colonial past where 80 percent of the population was kept from participating in society by literacy voting laws. The book draws on sources as diverse as academic studies done as degree work by former missionaries, to declassed information from the State Department files. Events, both local and global, had their impact. Such political currents as those represented by Nazi Klaus Barbie and communist Che Guevara occurred in Bolivia. On the world scene, it ranged from Peron in Argentina to the assassination of President Kennedy in the U.S. While the book is about a missionary family, it so contextualizes them into the social, economic, and political situation in Bolivia, one comes away with a deeper appreciation for and understanding of those who dedicate their lives to the well-being of the world’s poorest and most marginalized.
The Hidden War in Argentina by Panagiotis Dimitrakis Pdf
"Though officially neutral until March 1945, Buenos Aires played a key role during World War II as a base for the South American intelligence operations of the major powers. The Hidden War in Argentina reveals the stories of the spymasters, British, Americans and Germans who plotted against each other throughout the Second World War in Argentina. In Buenos Aires, Johannes Siegfried Becker - codename 'Sargo' ?́" was the man responsible for organizing most of the Nazi intelligence gathering in Latin America and the leader of 'Operation Bolivar', which sought to bring South America into the war on the side of the Axis powers. After the attack on Pearl Harbor the US state department pressured every South American country to join it in declaring war on Germany, and J Edgar Hoover authorized huge investments in South American intelligence operations. Argentina continued to refuse to join the conflict, triggering a US embargo that squeezed the country's economy to breaking point. Buenos Aires continued to be a hub for espionage even as the war in Europe was ending ?́" hundreds of high-ranking Nazi exiles sought refuge there. This book is based on newly declassified files and details of the operations of MI6, the Abwehr, the Sicherheitsdienst (SD) and the FBI, as well as the OSS and the SOE. Most significantly, The Hidden War in Argentina reveals for the first time the coups of Britain's MI6 in South America."--
This recent government publication investigates an area often overlooked by historians: the impact of the Holocaust on the Western powers' intelligence-gathering community. A guide for researchers rather than a narrative study, it explains the archival organization of wartime records accumulated by the U.S. Army's Signal Intelligence Service and Britain's Government Code and Cypher School. In addition, it summarizes Holocaust-related information intercepted during the war years and deals at length with the fascinating question of how information about the Holocaust first reached the West. The guide begins with brief summaries of the history of anti-Semitism in the West and early Nazi policies in Germany. An overview of the Allies' system of gathering communications intelligence follows, along with a list of American and British sources of cryptologic records. A concise review of communications intelligence notes items of particular relevance to the Holocaust's historical narrative, and the book concludes with observations on cryptology and the Holocaust. Numerous photographs illuminate the text.

Strategy, Security, and Spies by María Emilia Paz Salinas Pdf
Faced with the possibility of being drawn into a war on several fronts, the United States sought to win Mexican support for a new strategy of Hemispheric Security, based on defense collaboration by governments throughout the Americas. U.S. leaders were concerned that Mexico might become a base for enemy operations, a scenario that, given the presence of pro-Axis lobbies in Mexico and the rumored fraternization between Mexico and Germany in World War I, seemed far from implausible in 1939&–41. Strategy, Security, and Spies tells the fascinating story of U.S. relations with Mexico during the war years, involving everything from spies and internal bureaucratic struggles in both countries to all sorts of diplomatic maneuverings. Although its focus is on the interactions of the two countries, relative to the threat posed by the Axis powers, a valuable feature of the study is to show how Mexico itself evolved politically in crucial ways during this period, always trying to maintain the delicate balance between the divisive force of Mexican nationalism and the countervailing force of economic dependency and security self-interest.
U.s. Army Signals Intelligence In World War Ii by James L. Gilbert,John Patrick Finnegan Pdf
This book is part of the Army historical community's commemoration of the fiftieth anniversary of World War II. American victory in that conflict was brought about not only by the valor of our fighting men and the immensity of our productive capacity, but also by the availability of superb military intelligence. Much of this intelligence came from the ability of our armed forces to intercept and decipher the most secret communications of their adversaries. For many years security considerations prevented any public mention of these successes in the official histories. Now much of the story can be told. To preserve the memory of the Army's role in this intelligence war, the U. S. Army Center of Military History has joined with the History Office, U. S. Army Intelligence and Security Command (INSCOM), to publish this collection of documents on Army signals intelligence in World War II. INSCOM carries on the heritage of the Army's World War II Signal Security Agency, which by breaking the Japanese diplomatic ciphers and military codes helped speed the way of our forces to victory. The book is intended both for an Army audience and for the general public - including those World War II veterans who participated in the signals intelligence war and who for so many years were constrained to keep their contributions secret. The security barriers have now been lifted, and the Army is proud to acknowledge those contributions. Harold W. NelsonCharles F.

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.
One of WW2 Reads "Top 20 Must-Read WWII Books of 2018" • A Christian Science Monitor Best Book of September •One of The Progressive's "Favorite Books of 2018" The gripping and little known story of the fight for the allegiance of Latin America during World War II The Tango War by Mary Jo McConahay fills an important gap in WWII history. Beginning in the thirties, both sides were well aware of the need to control not just the hearts and minds but also the resources of Latin America. The fight was often dirty: residents were captured to exchange for U.S. prisoners of war and rival spy networks shadowed each other across the continent. At all times it was a Tango War, in which each side closely shadowed the other’s steps. Though the Allies triumphed, at the war’s inception it looked like the Axis would win. A flow of raw materials in the Southern Hemisphere, at a high cost in lives, was key to ensuring Allied victory, as were military bases supporting the North African campaign, the Battle of the Atlantic and the invasion of Sicily, and fending off attacks on the Panama Canal. Allies secured loyalty through espionage and diplomacy—including help from Hollywood and Mickey Mouse—while Jews and innocents among ethnic groups —Japanese, Germans—paid an unconscionable price. Mexican pilots flew in the Philippines and twenty-five thousand Brazilians breached the Gothic Line in Italy. The Tango War also describes the machinations behind the greatest mass flight of criminals of the century, fascists with blood on their hands who escaped to the Americas. A true, shocking account that reads like a thriller, The Tango War shows in a new way how WWII was truly a global war.
