American Signal Intelligence in Northwest Africa and Western Europe is part of a series of books by the United States National Security Agency. They document what Winston Churchill called the "Wizard War." This gleaning of the Axis strategy, plans and tactical information from interception of radio communication was crucial to the victory over the Axis in World War II. This book documents these activities in both Northwest Africa and Europe. As a United States Government publication, it is in the public domain.

The volume at hand, Dr. George F. Howe's American Signals Intelligence in Northwest Africa and Western Europe is important professional reading for those interested in cryptologic history or in World War II. Dr. Howe's book deals primarily with organizational matters for providing SIGINT support in combat. Thus, the reader will not find stories of high-level cryptanalysis underlying big decisions by famous leaders. In my estimation, by concentrating on the less flashy aspects of wartime support in favor of the background work, Dr. Howe has again added a dimension of great worth to our knowledge of SIGINT and of the war. The study of World War II SIGINT has concentrated, by and large, on ULTRA, the exploitation of high-grade cryptographic systems used by Germany and Japan, and the use of ULTRA material by senior wartime decision makers. This effort unquestionably is important for understanding the decisions and events of that terrible era, but the overwhelming focus on this aspect has resulted in a slightly skewed understanding. The production of ULTRA and its effective use depended on a strong and well-organized structure working in conjunction with now-legendary cryptanalysts. Since the distribution of ULTRA was limited to a small number of officers and civilian leaders, the bulk of SIGINT support to the warfighter cam from tactical SIGINT units working at or near the front lines. This is an important subject for understanding what happened in World War II and for studying the principles of SIGINT organization today.

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.

In order for all applications of airpower -- including counter-air, deep interdiction strike, air landing, and combat search and rescue -- to succeed, they must be informed by comprehensive data on targets. Moreover, it would be helpful if intelligence included the intentions and capabilities of opponents. Getting signals intelligence data to the cockpit and pilots for instantaneous use on the battlefield is the objective. Signals intelligence can provide needed information, but its collection, processing, analysis, and distribution is secretive. Consequently, an operator is slow to get even minimal data. Real-time signals intelligence support to the cockpit is an on-going challenge, but it is not as cosmic or fantasy-based as some believe. Three historical examples illustrate what can be done when operations and intelligence ensure that critical data reach the battlefield in a timely fashion.

Getting the Message Through, the companion volume to Rebecca Robbins Raines' Signal Corps, traces the evolution of the corps from the appointment of the first signal officer on the eve of the Civil War, through its stages of growth and change, to its service in Operation DESERT SHIELD/DESERT STORM. Raines highlights not only the increasingly specialized nature of warfare and the rise of sophisticated communications technology, but also such diverse missions as weather reporting and military aviation. Information dominance in the form of superior communications is considered to be sine qua non to modern warfare. As Raines ably shows, the Signal Corps--once considered by some Army officers to be of little or no military value--and the communications it provides have become integral to all aspects of military operations on modern digitized battlefields. The volume is an invaluable reference source for anyone interested in the institutional history of the branch.

Based on extensive archival research in six countries and intensive fieldwork, the book analyzes the history of the village of Nkholongue on the eastern (Mozambican) shores of Lake Malawi from the time of its formation in the 19th century to the present day. The study uses Nkholongue as a microhistorical lens to examine such diverse topics as the slave trade, the spread of Islam, colonization, subsistence production, counter-insurgency, decolonization, civil war, ecotourism, and matriliny. Thereby, the book attempts to reflect as much as possible on the generalizability and (global) comparability of local findings by framing analyses in historiographical discussions that aim to go beyond the regional or national level. Although the chapters of the book deal with very different topics, they are united by a common interest in the social history of rural Africa in the longue durée. Contrary to persistent clichés of rural inertia in Africa, the book as a whole underscores the profound changeability of social conditions and relations in Nkholongue over the years and highlights how people’s room for maneuver kept changing as a result of the Winds of History, the frequent and often violent ruptures brought to the village from outside.

For the first time, the inside story of the brilliant American engineer who defeated Enigma and the Nazi code-masters Much has been written about the success of the British “Ultra” program in cracking the Germans’ Enigma code early in World War II, but few know what really happened in 1942, when the Germans added a fourth rotor to the machine that created the already challenging naval code and plunged Allied intelligence into darkness. Enter one Joe Desch, an unassuming but brilliant engineer at the National Cash Register Company in Dayton, Ohio, who was given the task of creating a machine to break the new Enigma settings. It was an enterprise that rivaled the Manhattan Project for secrecy and complexity–and nearly drove Desch to a breakdown. Under enormous pressure, he succeeded in creating a 5,000-pound electromechanical monster known as the Desch Bombe, which helped turn the tide in the Battle of the Atlantic–but not before a disgruntled co-worker attempted to leak information about the machine to the Nazis. After toiling anonymously–it even took his daughter years to learn of his accomplishments–Desch was awarded the National Medal of Merit, the country’s highest civilian honor. In The Secret in Building 26, the entire thrilling story of the final triumph over Enigma is finally told.

Cracking the enemy's radio code is a task so urgent and so difficult that it demands the military's best minds and most sophisticated technology. But when the coded messages are in a language as complex as Japanese, decoding problems multiply dramatically.
