Book Description
In the foreword to this book, first published in 1978, Sen. Daniel Inouye describes the story as ""the raw material of adventure fiction--but this is all true and told in a manner that is at the same time fascinating and professional."" Despite the passage of twenty years and the appearance of several studies of code breaking, this inside look at naval intelligence in the Pacific is as powerful as ever. This book provides a compassionate and unique understanding of the war and the business of intelligence gathering. Assigned to the combat intelligence unit in Honolulu from June 1941 to the end of the war, W. J. Holmes shares his history-making experiences as part of an organization that collected, analyzed, and disseminated naval intelligence throughout World War II. His book not only captures the mood of the period but gives rare insight into the problems and personalities involved, allowing the reader to fully appreciate the painful moral dilemma faced daily by commanders in the Pacific once the Japanese naval codes were broken. Every time the Americans made use of the enemy messages they had decoded, they increased the probability of the Japanese realizing what had happened and changing their codes. And such a change would cause the U.S. Pacific Fleet to lose a vital edge. On the other hand, withholding the information could--and sometimes did--result in the loss of U.S. lives and ships. This revealing study illuminates the difficulties in both collecting intelligence and deciding when to use it.

Book Description
This is the history of the founding in 1882 and operation through two world wars of America's first permanent intelligence agency, the Office of Naval Intelligence. In this study Dr. Jeffery M. Dorwart shows how and why a tiny late 19th century U.S. Navy bureau created to collect information about foreign warship design became during two world wars a complex and sometimes troubled domestic and worldwide intelligence agency. More significantly, this history of O.N.I. demonstrates how the founders and first generations of U.S. naval officers trained to man warships at sea confronted what seemed an inherent dilemma in new missions that interfered with providing technical and operational information to their navy. Dorwart explains the forces that created this dilemma and how ONI officers responded in different ways to their intelligence mission. This history recounts how from the very beginning ONI duty during the last decades of the 19th century seemed conflicting. Some found the new assignment very rewarding in collecting and collating data for the U.S. to build a "New Navy" of steel and steam-powered warships armed with the latest rifled ordnance. But other naval officers saw assignment to this tiny office as a monotonous dead-end assignment endangering their careers as shipboard operators. Dorwart shows how the first and second world wars and interwar period dramatically accelerated the naval intelligence office's dilemma. The threats in both oceans from powerful enemy navies equipped with the latest technology and weaponry gave an urgency to the collection of information on the strategies, warships, submarines, and aircraft development of potential and actual naval enemies. But at the same time ONI was asked to provide information of possible domestic threats from suspected enemy spies, terrorists, saboteurs or anti-war opponents. This led ONI officers to wiretap, break and enter, pursue surveillance of all types of people from foreign agents to Americans suspected of opposition to strengthening the U.S. Navy or becoming involved in world wars. This history explains that many ONI directors and officers were highly motivated to collect as much information as possible about the naval-military capabilities and strategies of Germany, Italy, Japan, and even allies. ONI officers understood that code-breaking was part of their job as well. But this all led some to become deeply involved in domestic spying, wiretapping, breaking and entering on private property. These extralegal and at times illegal operations, Dorwart argues, confused some ONI officers, leading to too much information that clouded vital intelligence such as Japanese plans to attack American naval bases. In the end, this study demonstrates the dilemma confronted between 1882 and 1945 by dedicated U.S. naval officers attached to or collecting information worldwide for the Office of Naval Intelligence.

Book Description
The classic book that established the principles and methods of modern intelligence analysis With the outbreak of the Second World War, historian Sherman Kent left his classroom at Yale to join the Office of Strategic Services—the forerunner of the Central Intelligence Agency—where he adapted scholarly methods to the rigors and unique challenges of producing actionable intelligence in support of the war effort. In this remarkable book, Kent draws on the lessons he learned in wartime to lay the foundations for postwar security. He presents the doctrine and practices of intelligence analysis and explains why they are vital to national survival. Strategic Intelligence for American World Policy shows how intelligence activities and their consequences extend far beyond military considerations and are as essential to keeping the peace as they are to winning the war.

Book Description
U.S. Navy Intelligence Contribution Key to SE Asia War Effort from 1965-75 Knowing the Enemy, part of the commemorative series The U.S. Navy and the Vietnam War, covers the Navy intelligence establishment's support to the war effort in Southeast Asia from 1965 to 1975. It describes the contribution of naval intelligence to key strategic, operational, and tactical aspects of the war including the involvement of intelligence in the seminal Tonkin Gulf Crisis of 1964 and the Rolling Thunder and Linebacker bombing campaigns; the monitoring of Sino-Soviet bloc military assistance to Hanoi; the operation of the Seventh Fleet's reconnaissance aircraft; the enemy's use of the "neutral" Cambodian port of Sihanoukvil≤ and the support to U.S. Navy riverine operations during the Tet Offensive and the SEALORDS campaign in South Vietnam. Special features elaborate on the experiences of reconnaissance plane pilots navigating the dangerous skies of Indochina; intelligence professionals who braved enemy attacks at shore bases in South Vietnam; the perilous mission in Laos of Observation Squadron 67 (VO-67); the secret voyage of nuclear attack submarine Sculpin (SSN-590); and the leadership and heroism of Captain Earl F. Rectanus, Lieutenant Commander Jack Graf, and other naval intelligence professionals who risked, and sometimes lost, their lives in the service of their country during the war. The work is lavishly illustrated with more than 85 photographs and maps, and includes a select list of suggested readings. This publication will be of interest and value to scholars, veterans, and students of the Vietnam War and the Navy's role in that conflict.

Book Description
How can the United States avoid a future surprise attack on the scale of 9/11 or Pearl Harbor, in an era when such devastating attacks can come not only from nation states, but also from terrorist groups or cyber enemies? Intelligence and Surprise Attack examines why surprise attacks often succeed even though, in most cases, warnings had been available beforehand. Erik J. Dahl challenges the conventional wisdom about intelligence failure, which holds that attacks succeed because important warnings get lost amid noise or because intelligence officials lack the imagination and collaboration to “connect the dots” of available information. Comparing cases of intelligence failure with intelligence success, Dahl finds that the key to success is not more imagination or better analysis, but better acquisition of precise, tactical-level intelligence combined with the presence of decision makers who are willing to listen to and act on the warnings they receive from their intelligence staff. The book offers a new understanding of classic cases of conventional and terrorist attacks such as Pearl Harbor, the Battle of Midway, and the bombings of US embassies in Kenya and Tanzania. The book also presents a comprehensive analysis of the intelligence picture before the 9/11 attacks, making use of new information available since the publication of the 9/11 Commission Report and challenging some of that report’s findings.

Book Description
This book counters such revisionist arguments. Matthew Seligmann disputes the suggestion that the British government either got its facts wrong about the German threat or even, as some have claimed, deliberately 'invented' it in order to justify an otherwise unnecessary alignment with France and Russia. By examining the military and naval intelligence assessments forwarded from Germany to London by Britain's service attaches in Berlin, its 'men on the spot', Spies in Uniform clearly demonstrates that the British authorities had every reason to be alarmed.
