Languages : en
Pages : 256

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.

Dorwart's History of the Office of Naval Intelligence, 1865–1945 PDF Author: Jeffery Dorwart
Publisher: Naval Institute Press
ISBN: 1591146194
Category : History
Languages : en
Pages : 539

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.

Strategic Intelligence for American World Policy

Strategic Intelligence for American World Policy PDF Author: Sherman Kent
Publisher: Princeton University Press
ISBN: 069127374X
Category : Political Science
Languages : en
Pages : 258

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.

British Naval Intelligence through the Twentieth Century

British Naval Intelligence through the Twentieth Century PDF Author: Andrew Boyd
Publisher: Seaforth Publishing
ISBN: 1526736608
Category : History
Languages : en
Pages : 757

Book Description
An acclaimed military historian examines the vital role of British naval intelligence from the mid-nineteenth century to the end of the Cold War. In this comprehensive account, Andrew Boyd brings a critical new dimension to our understanding of British naval intelligence. From the capture of Napoleons signal codes to the satellite-based systems of the Cold War era, he provides a coherent and reliable overview while setting his subject in the larger context of the British state. It is a fascinating study of how naval needs and personalities shaped the British intelligence community that exists today. Boyd explains why and how intelligence was collected and assesses its real impact on policy and operations. Though he confirms that naval intelligence was critical to Britains victory in both World Wars, he significantly reappraises its role in each. He reveals that coverage of Germany before 1914 and of the three Axis powers in the interwar period was more comprehensive and effective than previously suggested; and while British power declined rapidly after 1945, the book shows how intelligence helped the Royal Navy to remain a significant global force for the rest of the twentieth century.

Intelligence and Surprise Attack

Intelligence and Surprise Attack PDF Author: Erik J. Dahl
Publisher: Georgetown University Press
ISBN: 1589019989
Category : Political Science
Languages : en
Pages : 289

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.
