"Historians have paid little attention to the British Army's experience with signals intelligence during the First World War. However, this was one of the Army's most important sources of information about crucial matters such as the order of battle and intentions of the German and Turkish Armies. Britain's successes and failures in signals intelligence profoundly affected battles ranging from the race for the Channel Ports, first Somme, third Gaza and Amiens, among many others." "While efforts to weed the records on these topics have created major gaps in the sources, surviving evidence throws an entirely new light on the British Army in the Great War. It allows one to trace the evolution of the Army's signals intelligence organisations, to determine many of their successes and failures, to show how this intelligence affected various operations and, indeed, to demonstrate that signals intelligence influenced the operations of the British Army as much as those of the Royal Navy." "The material reproduced in this volume includes excerpts from reports by Army Headquarters in France, Italy and Mesopotamia and the Military Intelligence Directorate. It includes the memorandum "Enemy Codes and their Solution" by the G.H.Q. codebreaking section in January 1918, which is one of the two best sources known to exist about the techniques of "codebreaking"; surviving reports on the enemy radio networks in the Balkans and Anatolian Turkey, which are the most illuminating evidence from any theatre on the approach toward "traffic analysis" and a report on the breaking of German and Turkish Army ciphers in Mesopotamia during 1917, which is the best source known about the techniques of "cryptanalysis" used by an Army in the Great War."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Signals Intelligence, or SIGINT, is the interception and evaluation of coded enemy messages. From Enigma to Ultra, Purple to Lorenz, Room 40 to Bletchley, SIGINT has been instrumental in both victory and defeat during the First and Second World War. In the First World War, a vast network of signals rapidly expanded across the globe, spawning a new breed of spies and intelligence operatives to code, de-code and analyse thousands of messages. As a result, signallers and cryptographers in the Admiralty's famous Room 40 paved the way for the code breakers of Bletchley Park in the Second World War. In the ensuing war years the world battled against a web of signals intelligence that gave birth to Enigma and Ultra, and saw agents from Britain, France, Germany, Russia, America and Japan race to outwit each other through infinitely complex codes. For the first time, Peter Matthews reveals the secret history of global signals intelligence during the world wars through original interviews with German interceptors, British code breakers, and US and Russian cryptographers. " SIGINT is a fascinating account of what Allied investigators learned postwar about the Nazi equivalent of Bletchley Park. Turns out, 60,000 crptographers, analysts and linguists achieved considerable success in solving intercepted traffic, and even broke the Swiss Enigma! Based on recently declassifed NSA document, this is a great contribution to the literature." - The St Ermin's Hotel Intelligence Book of the Year Award 2014

Brash hustlers, sinister colonels, resilient refugees, and intrepid radio hosts: meet the future of Congo In this extraordinary debut – called ‘gripping’ by The Times of London – Ben Rawlence sets out to gather the news from a forgotten town deep in Congo’s ‘silent quarter’ where peace is finally being built after two decades of civil war and devastation. Ignoring the advice of locals, reporters, and mercenaries, he travels by foot, bike, and boat, introducing us to Colonel Ibrahim, a guerrilla turned army officer; Benjamin, the kindly father of the most terrifying Mai Mai warlord; the cousins Mohammed and Mohammed, young tin traders hoping to make their fortune; and talk show host Mama Christine, who dispenses counsel and courage in equal measure. From the ‘blood cheese’ of Goma to the decaying city of Manono, Rawlence uncovers the real stories of life during the war and finds hope for the future.

The 1982 Falklands War was not only one of the most extraordinary military confrontations of recent years but also a turning point in the politics of Britain and Argentina. This unusual book makes it possible for us to follow the development of the war from both sides, as two leading experts from the belligerents present an integrated, authoritative, and engrossing account of its origins and course. The work unravels the complex series of events leading to the occupation of the Falkland Islands on April 2, 1982 by Argentine forces and then follows the conflict through to their surrender to the British on June 14. The authors weave together the development of the military confrontation with the attempts by Americans, Peruvians, and the United Nations to help find solutions. Originally published in 1991.

In recent years the importance of Signals Intelligence (Sigint) has become more prominent, especially the capabilities of reading and deciphering diplomatic, military and commercial communications of other nations. This work reveals the role of intercepting messages during the Cold War.

The ability to communicate is a prerequisite for success both in military and civil life. Surprisingly, everyone expects access to communications, but rarely wonders how it is achieved. The purpose of this book is to bring into focus one of the cornerstones of the success of the British Army, and to provide an insight into the complexity and diversity of the Royal Corps of Signals. This is done, not by narrative, but by delving into unit history rather than campaign history, thus offering a different perspective for the historian. Royal Signals is one of the largest Corps in the British Army, and consists of a body of very highly trained and dedicated personnel to manage, operate, and repair the advanced technology that is theirs to administer. Signals are the Invisible Elite, without them there is no victory. Before the independent Corps of Signals was formed in 1920, Royal Engineers provided communications for much of the Army. Details of their signal units are included. Reflecting the new technologies as they occur, the reader will see the new signal units being raised to facilitate the exigencies of the time. For example, during the Second World War the Golden Arrow Detachments were created as independent, mobile, high-speed transmitting and receiving stations to provide links to Britain, and thus provide High Command with the information from Commanders in the Field that was desperately needed. These units also passed intercepted enemy signals back to England for the code breakers at Bletchley Park. Other specialist Signal units were created for Air Support, Para Signals, Commandos, Interception, Fixed Communications, Peacekeeping and a multitude of other reasons. In today's changing world signals continue to get their message through - Swift and Sure. This book is a must for historians, genealogists, and those that served. It contains: - Overviews of the Signals Order of Battle at specific times in history- Detailed précis of specialist signal units including Commando, and Para units.- History of 35 Commonwealth and related Signal Corps- Photographs of many rare signal badges- Scores and scores of unit histories both Regular and Territorial from the past to the present

A sweeping history of Latin American republicanism in the nineteenth century By the 1820s, after three centuries under imperial rule, the former Spanish territories of Latin America had shaken off their colonial bonds and founded independent republics. In committing themselves to republicanism, they embarked on a political experiment of an unprecedented scale outside the newly formed United States. In this book, Hilda Sabato provides a sweeping history of republicanism in nineteenth-century Latin America, one that spans the entire region and places the Spanish American experience within a broader global perspective. Challenging the conventional view of Latin America as a case of failed modernization, Sabato shows how republican experiments differed across the region yet were all based on the radical notion of popular sovereignty--the idea that legitimate authority lies with the people. As in other parts of the world, the transition from colonies to independent states was complex, uncertain, and rife with conflict. Yet the republican order in Spanish America endured, crossing borders and traversing distinct geographies and cultures. Sabato shifts the focus from rulers and elites to ordinary citizens and traces the emergence of new institutions and practices that shaped a vigorous and inclusive political life. Panoramic in scope and certain to provoke debate, this book situates these fledgling republics in the context of a transatlantic shift in how government was conceived and practiced, and puts Latin America at the center of a revolutionary age that gave birth to new ideas of citizenship.

Given the appalling consequences of civil wars, why are the competing actors within a state unable to come to a settlement to avoid the costs of conflict? How might external parties affect the likelihood that a civil war begins? How do their actions affect the duration and outcome of civil conflicts that are already underway? How International Relations Affect Civil Conflict draws on three main approaches--bargaining theory, signaling theory, and rational expectations--to examine how external actors might affect the onset, duration and outcome of civil wars. Signals from external actors are important because they represent a potential increase (or decrease) in fighting capabilities for the government or the opposition if a war were to begin. Costly signals should not affect the probability of civil war onset because they are readily observable ex ante, which allows the government and opposition to peacefully adjust their bargaining positions based on changes in relative capabilities. In contrast, cheap hostile signals make civil war more likely by increasing the risk that an opposition group overestimates its ability to stage a successful rebellion with external support. Cheap supportive signals work in the opposite manner because they represent increased fighting capabilities for the government. Furthermore, signals sent in the pre-war period have important implications for the duration and outcome of civil conflicts because competing intrastate actors develop expectations for future interventions prior to deciding to fight. In this book, Clayton L. Thyne tests this theory by examining the likelihood of civil war onset, the duration, and the outcome of all civil wars since 1945, finding strong support from empirical tests for each component of this theory. The conclusion offers specific advice to US policy-makers to prevent the outbreak of civil conflict in states most at-risk for civil war and to help end those that are currently underway.
