How was Bletchley Park made as an organization? How was signals intelligence constructed as a field? What was Bletchley Park's culture and how was its work co-ordinated? Bletchley Park was not just the home of geniuses such as Alan Turing, it was also the workplace of thousands of other people, mostly women, and their organization was a key component in the cracking of Enigma. Challenging many popular perceptions, this book examines the hitherto unexamined complexities of how 10,000 people were brought together in complete secrecy during World War II to work on ciphers. Unlike most organizational studies, this book decodes, rather than encodes, the processes of organization and examines the structures, cultures and the work itself of Bletchley Park using archive and oral history sources. Organization theorists, intelligence historians and general readers alike will find in this book a challenge to their preconceptions of both Bletchley Park and organizational analysis.

At last - the secrets of Bletchley Park's powerful codebreaking computers. This is a history of Colossus, the world's first fully-functioning electronic digital computer. Colossus was used during the Second World War at the Government Code and Cypher School at Bletchley Park, where it played an invaluable role cracking enemy codes. Until very recently, much about the Colossus machine was shrouded in secrecy, largely because the codes that were employed remained in use by the British security services until a short time ago. This book only became possible due to the declassification in the US of wartime documents. With an introductory essay on cryptography and the history of code-breaking by Simon Singh, this book reveals the workings of Colossus and the extraordinary staff at Bletchley Park through personal accounts by those who lived and worked with the computer. Among them is the testimony of Thomas Flowers, who was the architect of Colossus and whose personal account, written shortly before he died, is published here for the first time. Other essays consider the historical importance of this remarkable machine, and its impact on the generations of computing technology that followed.

There have been a great many books written on military intelligence and the secret services rooted in the twentieth century, however there is very little covering the activities of the men involved in the establishment of this fascinating institution.

In 1974, the British government admitted that its WWII secret intelligence organization had read Germany's ciphers on a massive scale. The intelligence from these decrypts influenced the Atlantic, the Eastern Front and Normandy. Why did the Germans never realize the Allies had so thoroughly penetrated their communications? As German intelligence experts conducted numerous internal investigations that all certified their ciphers' security, the Allies continued to break more ciphers and plugged their own communication leaks. How were the Allies able to so thoroughly exploit Germany's secret messages? How did they keep their tremendous success a secret? What flaws in Germany's organization allowed this counterintelligence failure and how can today's organizations learn to avoid similar disasters? This book, the first comparative study of WWII SIGINT (Signals Intelligence), analyzes the characteristics that allowed the Allies SIGINT success and that fostered the German blindness to Enigma's compromise.

Learning from history helps states to create foreign and security policy that builds upon successes and avoids past mistakes. Louise Kettle's insightful analysis - drawing on a wealth of previously unseen documents, sourced by Freedom of Information requests, together with interviews with government and intelligence agency officials - questions whether the British government actually learns from history. This is achieved through an extended commentary on military interventions in the Middle East since the 1950s, including a behind-the-scenes glimpse into Whitehall decision-making and a critical examination of the 2016 Iraq Inquiry report.

Bletchley Park was arguably the most successful intelligence agency in world history, the top secret workplace of the remarkable people who cracked Germany's vaunted Enigma Code. Almost to the end of the war, the Germans had firm faith in the Enigma ciphering machine, but in fact the codebreakers were deciphering nearly 4,000 German transmissions daily by 1942. Indeed, Winston Churchill hailed the work of Bletchley Park as the `secret weapon' that won the war.

This is the first study to investigate the interlinked problems of domestic security and national defence in Ireland, from independence to the present day. Using a wealth of newly released material from Irish and foreign archives, Professor O'Halpin describes the development of the army and police since 1922, and examines how the emerging Irish state tried to balance an absolute commitment to military neutrality and independent defence with the need for close co-operation with Britain in dealing with perceived republican and communist threats.

The Cambridge Spies continue to fascinate - but one of them, John Cairncross, has always been more of an enigma than the others. He worked alone and was driven by his hostility to Fascism rather than to the promotion of Communism. During his war-time work at Bletchley Park, he passed documents to the Soviets which went on to influence the Battle of Kursk. Now, Geoff Andrews has access to the Cairncross papers and secrets, and has spoken to friends, relatives and former colleagues. A complex individual emerges - a scholar as well as a spy - whose motivations have often been misunderstood. After his resignation from the Civil Service, Cairncross moved to Italy and here he rebuilt his life as a foreign correspondent, editor and university professor. This gave him new circles and friendships - which included the writer Graham Greene - while he always lived with the fear that his earlier espionage would come to light. The full account of Cairncross's spying, his confession and his dramatic public exposure as the 'fifth man' will be told here for the first time, while also unveiling the story of his post-espionage life.

This text draws together the various strands of Irish national security policy and practice in a single chronological study, from independence in 1922, analyzing the rapid emergence of a complex external security policy combining an absolute commitment to military neutrality and independent defence. The author traces the development of the army and police force in the new Irish state and the close co-operation with Britain over issues of joint concern such as security and immigration. He also examines the state's reaction to the enduring republican threat, casting fresh light on how far the state was willing to put key constitutional protections into abeyance in its conflict with the republican movement. The book also examines the clandestine intelligence activities of belligerent powers during the World War II, documenting the growth of the state's close wartime security understandings with the Allied powers, and the evolution of Cold War links with MI5 and the CIA. This book is intended for general readers of Irish history and scholars and students of 20th-century British and Irish history, and of politics and international relations.

A Cross of Iron provides the fullest account yet of the national security state that emerged in the first decade of the Cold War. Michael J. Hogan traces the process of state-making through struggles to unify the armed forces, harness science to military purposes, mobilize military manpower, control the defense budget, and distribute the cost of defense across the economy. President Harry S. Truman and his successor were in the middle of a fundamental contest over the nation's political identity and postwar purpose, and their efforts determined the size and shape of the national security state that finally emerged.

Intelligence and Espionage: Secrets and Spies provides a global introduction to the role of intelligence - a key, but sometimes controversial, aspect of ensuring national security. Separating fact from fiction, the book draws on past examples to explore the use and misuse of intelligence, examine why failures take place and address important ethical issues over its use. Divided into two parts, the book adopts a thematic approach to the topic, guiding the reader through the collection and analysis of information and its use by policymakers, before looking at intelligence sharing. Lomas and Murphy also explore the important associated activities of counterintelligence and the use of covert action, to influence foreign countries and individuals. Topics covered include human and signals intelligence, the Cuban Missile Crisis, intelligence and Stalin, Trump and the US intelligence community, and the Soviet Bloc. This analysis is supplemented by a comprehensive documents section, containing newly released documents, including material from Edward Snowden's leaks of classified material. Supported by images, a comprehensive chronology, glossary, and 'who's who' of key figures, Intelligence and Espionage is an invaluable resource for anyone interested in the role of intelligence in policymaking, international relations and diplomacy, warfighting and politics to the present day.

The Center for the Study of Intelligence (CSI) was founded in 1974 in response to Director of Central Intelligence James Schlesinger's desire to create within the CIA an organisation that could "think through the functions of intelligence and bring the best intellects available to bear on intelligence problems". The centre, comprising professional historians and experienced practitioners, attempts to document lessons learned from past activities, to explore the needs and expectations of intelligence consumers, and to stimulate serious debate about current and future intelligence challenges. This book examines the numerous books and monographs addressing historical, operational, doctrinal and theoretical aspects of the intelligence profession and its relation to modern media.

Have Western experts fundamentally failed to understand the dynamics, leaders and culture of the Middle East? Dina Rezk analyses 8 case studies, culminating in the assassination of Egyptian President Anwar el Sadat on live television on 6 October 1981, Drawing on declassified documents, interviews and multi-archival research, she explores how the most powerful intelligence agencies in the world have been so notoriously caught off guard in post-WWII Middle East.

This is both a history of the service attache, beginning with the Napoleonic era, and a discussion of his changing role, past and present. Professor Vagts shows the military adviser temporarily joined to the diplomatic corps as a person often divided in his loyalties to diplomatic officials and to military leaders. Affected by increasing bureaucratic specialization, he sometimes became a "twilight" figure engaged in political activity and even espionage. Professor Vagts' numerous works on the history of militarism and the military, in both German and English, and his research in the chancelleries of Europe have given him perspective for this book. Originally published in 1967. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

If you loved American Sniper you will love Not a Good Day to Die: The Untold Story of Operation Anaconda. Award-winning journalist Sean Naylor, an eyewitness to the action, vividly portrays the fight for Afghanistan's most hostile battleground. At dawn on March 2, 2002, the first major battle of the 21st Century began. Over 200 soldiers of the 101st Airborne and 10th Mountain Divisions flew into Afghanistan's Shahikot valley - and into the mouth of a buzz-saw. They were about to pay a bloody price for strategic, higher-level miscalculations that underestimated the enemy's strength and willingness to fight. After the attacks of September 11, 2001, Coalition forces quickly toppled the Taliban regime from the seat of government. But, believing the war to be all but over, the Pentagon and US Central Command refused to commit the forces required to achieve total victory in Afghanistan. Instead, they delegated responsibility for fighting the war's biggest battle to a tangle of untested units thrown together at the last moment. Then the world watched as Anaconda seemed to unravel. Denied the extra infantry, artillery and close air support with which they trained to go to war, the soldiers of this airborne assault fought for survival in brutal high-altitude combat. Backed up by a small, but crucial, team of special forces, they were all that stood between the Coalition and a military disaster. Perfect for fans of Black Hawk Down, Zero Dark Thirty, Chris Ryan, and Andy McNab. About the author: Sean Naylor is a senior writer for the Army Times. He has covered the Afghan mujahideen's war against the Soviets, and American military operations in Somalia, Haiti, Bosnia, Afghanistan, and Iraq. Named one of the 22 "unsung" influential print reporters in Washington by American Journalism Review in May 2002, he earned the White House Correspondents' Association's prestigious Edgar A. Poe Award for his coverage of Operation Anaconda.

Traditionally the military community held the intelligence profession in low esteem, spying was seen as dirty work and information was all to often ignored if it conflicted with a commander's own view. Handel examines the ways in which this situation has improved and argues that co-operation between the intelligence adviser and the military decision maker is vital.

The exposure of two senior republicans as informers for British intelligence in 2005 led to a popular perception that the IRA had 'lost' the intelligence war and was pressurised into peace. In this first in-depth study across the entire conflict, Thomas Leahy re-evaluates the successes and failures of Britain's intelligence activities against the IRA, from the use of agents and informers to special-forces, surveillance and electronic intelligence. Using new interview material alongside memoirs and Irish and UK archival materials, he suggests that the IRA was not forced into peace by British intelligence. His work sheds new light on key questions in intelligence and security studies. How does British intelligence operate against paramilitaries? Is it effective? When should governments 'talk to terrorists'? And does regional variation explain the outcome of intelligence conflicts? This is a major contribution to the history of the conflict and of why peace emerged in Northern Ireland.

There are a limited number of intelligence analysis books available on the market. 　Intelligence Analysis Fundamentals is an introductory, accessible text for college level undergraduate and graduate level courses. While the principles outlined in the book largely follow military intelligence terminology and practice, concepts are presented to correlate with intelligence gathering and analysis performed in law enforcement, homeland security, and corporate and business security roles. Most of the existing texts on intelligence gathering and analysis focus on specific types of intelligence such as ‘target centric’ intelligence, and many of these, detail information from a position of prior knowledge. In other words, they are most valuable to the consumer who has a working-level knowledge of the subject.

The book is general enough in nature that a lay student—interested in pursuing a career in intelligence, Homeland Security, or other related areas of law enforcement—will benefit from it. 　No prior knowledge of intelligence analysis, functions, or operations is assumed.　 Chapters illustrate methods and techniques that, over the years, have consistently demonstrate results, superior to those achieved with other means. Chapters describe such analytical methods that are most widely used in the intelligence community and serve as recognized standards and benchmarks in the practice of intelligence analysis. 　All techniques have been selected for inclusion for their specific application to homeland security, criminal investigations, and intelligence operations. 　

Uses numerous hands-on activities—that can easily be modified by instructors to be more or less challenging depending on the course level—to reinforce concepts

As current and active members of the intelligence community, the authors draw on their decades of experience in intelligence to offer real-world examples to illustrate concepts

All methodologies reflect the latest trends in the intelligence communities assessment, analysis, and reporting processes with all presented being open source, non-classified information

As such, the non-sensitive information presented is appropriate—and methods applicable—for use for education and training overseas and internationally

Military-style collection and analysis methods are the primary ones presented, but all are directly correlated intelligence to current concepts, functions and practices within Homeland Security and the law communities

Covers the counterterrorism environment where joint operations and investigative efforts combine military, private sector, and law enforcement action and information sharing

The book will be a welcome addition to the body of literature available and a widely used reference for professionals and students alike.

Kurt Frank Korf's story is one of the most unusual to come out of World War II. Although German-Americans were America's largest ethnic group, and German-Americans-including thousands of native-born Germans-fought bravely in all theaters, there are few full first-person accounts by German- Americans of their experiences during the 1930s and 1940s. Drawing on his correspondence and on oral histories and interviews with Korf, Patricia Kollander paints a fascinating portrait of a privileged young man forced to flee Nazi Germany in 1937 because the infamous Nuremburg Laws had relegated him to the status of "second-degree mixed breed" (Korf had one Jewish grandparent). Settling in New York City, Korf became an FBI informant, watching pro-Nazi leaders like Fritz Kuhn and the German-American Bund as they moved among the city's large German immigrant community. Soon after, he enlisted in the U.S. Army, serving in Germany as an intelligence officer during the Battle of the Bulge, and as a prisoner of war camp administrator. After the war, Korf stayed on as a U.S. government attorney in Berlin and Munich, working to hunt down war criminals, and lent his expertise in the effort to determine the authenticity of Joseph Goebbels's diaries. Kurt Frank Korf died in 2000. Kollander not only draws a detailed portrait of this unique figure; she also provides a rich context for exploring responses to Nazism in Germany, the German-American position before and during the war, the community's later response to Nazism and its crimes, and the broader issues of ethnicity, religion, political ideology, and patriotism in 20th-century America. Patricia Kollander is Associate Professor of History at Florida Atlantic University. She is the author of Frederick III: Germany's Liberal Emperor. "I Must Be a Part of This War" is part of her ongoing research into the experiences of some fifteen thousand native-born Germans who served in the U.S. Army in World War II. John O'Sullivan was Professor of History at Florida Atlantic University.

At the height of the Cold War, the U.S. government enlisted the aid of a select group of psychologists, sociologists, and political scientists to blueprint enemy behavior. Not only did these academics bring sophisticated concepts to what became a project of demonizing communist societies, but they influenced decision-making in the map rooms, prison camps, and battlefields of the Korean War and in Vietnam. With verve and insight, Ron Robin tells the intriguing story of the rise of behavioral scientists in government and how their potentially dangerous, "American" assumptions about human behavior would shape U.S. views of domestic disturbances and insurgencies in Third World countries for decades to come.

Based at government-funded think tanks, the experts devised provocative solutions for key Cold War dilemmas, including psychological warfare projects, negotiation strategies during the Korean armistice, and morale studies in the Vietnam era. Robin examines factors that shaped the scientists' thinking and explores their psycho-cultural and rational choice explanations for enemy behavior. He reveals how the academics' intolerance for complexity ultimately reduced the nation's adversaries to borderline psychotics, ignored revolutionary social shifts in post-World War II Asia, and promoted the notion of a maniacal threat facing the United States.

Putting the issue of scientific validity aside, Robin presents the first extensive analysis of the intellectual underpinnings of Cold War behavioral sciences in a book that will be indispensable reading for anyone interested in the era and its legacy.

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.

It took the U.S. Army a full two years after the attack on Pearl Harbor to break the codes of the Japanese Imperial Army. But by 1944 the U.S. was decoding more than 20,000 messages a month filled with information about enemy movements, strategy, fortifications, troop strengths, and supply convoys.

In "MacArthur's ULTRA," historian Edward Drea recounts the story behind the Army's painstaking decryption operation and its dramatic breakthrough. He demonstrates how ULTRA (intelligence from decrypted Japanese radio communications) shaped MacArthur's operations in New Guinea and the Philippines and its effect on the outcome of World War II.

From sources on both sides of the Pacific and national security agency declassified records, Drea has compiled a detailed listing of the ULTRA intelligence available to MacArthur. By correlating the existing intelligence with MacArthur's operational decisions, Drea shows how MacArthur usedand misusedintelligence information. He tells for the first time the story behind MacArthur's bold leap to Hollandia in 1944 and shows how ULTRA revealed the massive Japanese mobilization for what might have been (had it occurred) the bloodiest and most protracted engagement of the entire war the Allied invasion of Japan. Drea also clarifies the role of ULTRA in Truman's decision to drop atomic bombs on Japan in 1945, and concludes that ULTRA shortened the war by six to ten months.

In this pathbreaking book, Amy Zegart provides the first scholarly examination of the intelligence failures that preceded September 11. Until now, those failures have been attributed largely to individual mistakes. But Zegart shows how and why the intelligence system itself left us vulnerable.

Zegart argues that after the Cold War ended, the CIA and FBI failed to adapt to the rise of terrorism. She makes the case by conducting painstaking analysis of more than three hundred intelligence reform recommendations and tracing the history of CIA and FBI counterterrorism efforts from 1991 to 2001, drawing extensively from declassified government documents and interviews with more than seventy high-ranking government officials. She finds that political leaders were well aware of the emerging terrorist danger and the urgent need for intelligence reform, but failed to achieve the changes they sought. The same forces that have stymied intelligence reform for decades are to blame: resistance inside U.S. intelligence agencies, the rational interests of politicians and career bureaucrats, and core aspects of our democracy such as the fragmented structure of the federal government. Ultimately failures of adaptation led to failures of performance. Zegart reveals how longstanding organizational weaknesses left unaddressed during the 1990s prevented the CIA and FBI from capitalizing on twenty-three opportunities to disrupt the September 11 plot.

"Spying Blind" is a sobering account of why two of America's most important intelligence agencies failed to adjust to new threats after the Cold War, and why they are unlikely to adapt in the future.

Drawing on extensive interviews and archival research, this biography uncovers the motivations and ideals that informed Smiley's commitment to covert action and intelligence during the Second World War and early part of the Cold War, often among tribally based societies. With particular reference to operations in Albania, Oman and Yemen, it addresses the wider issues of accountability and control of clandestine operations.
