Book excerpt: 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 Synopsis The Elusive Enemy by : Douglas Ford

Download or read book The Elusive Enemy written by Douglas Ford. This book was released on 2011-10-15. Available in PDF, EPUB and Kindle. Book excerpt: The Elusive Enemy explores the evolution of U.S. intelligence concerning the combat capabilities of the Imperial Japanese Navy and its air arm during the interwar period and the Pacific War. Ford contends that the US Navy could not accurately determine the fighting efficiency of Japan’s forces until it engaged them in actual battle conditions over an extended period. As the conflict progressed, the Americans were able to rely on a growing array of intelligence material, including POWs, captured documents, and specimens of captured enemy weapons. These sources often revealed valuable information on the characteristics of Japanese equipment, as well as some of the ideas and doctrines which governed how they carried out their operations. First-hand observations of the Japanese navy’s performance in battle were the most frequently used source of intelligence which enabled the US Navy to develop a more informed assessment of its opponent. Ship crews, along with US aviators, were tasked to collect information by making a thorough observation of how the Japanese fought. Action reports described how the Imperial fleet demonstrated a number of weaknesses, the most important of which was a shortage of modern equipment and, after 1942, diminished air power. Yet, he demonstrates how the Japanese remained a resilient enemy who could be defeated only when the Americans deployed sufficient equipment and used it in an appropriate manner. The Office of Naval Intelligence, as well as the intelligence services operating in the Pacific theater, thus had to assess a wide array of conflicting characteristics, and provide a balanced evaluation concerning the strengths and weaknesses of the Imperial navy. At the same time, a large part of the intelligence analysis was undertaken by commanders in the Pacific Fleet. Naval personnel and aircrews assessed the information gained through encounters with the enemy so that they could develop a set of methods whereby US forces were able defeat the Japanese without incurring excessive casualties and losses. The intelligence services, in turn, played an important role in disseminating the information on the most efficient tactics and weapons that could be used to defeat the Imperial Fleet. The Elusive Enemy aims to explain how American perceptions concerning the Japanese navy evolved during the conflict, with a particular focus on the role of intelligence. It also seeks to introduce a new perspective on the question as to why the U.S. Navy carried out its campaigns during the Pacific War in the manner that it did.
