In 1940 the U.S. Army Signal Intelligence Service broke the Japanese diplomatic code. In 1975 Oshima Hiroshi, Japan's ambassador to Berlin during World War II, died, never knowing that the hundreds of messages he transmitted to Tokyo had been fully decoded by the Americans and whisked off to Washington, providing a major source of information for the Allies on Nazi activities. 
Resurrecting Oshima's decoded communications, which had remained classified for several decades, Carl Boyd provides a unique look at the Nazis from the perspective of a close foreign observer and ally. He uses Oshima's own words to reveal the thought and strategies of Adolf Hitler and other high-ranking Nazis, with whom Oshima associated. 
In addition to providing illuminating insight into Nazi activities and attitudes--military buildup in North Africa, the unwillingness to accept a separate peace with the Soviets--Boyd illustrates the functions of MAGIC. He demonstrates how that intelligence, gathered by teams of American cryptographers, influenced Allied strategy and helped bring about the downfall of Hitler and his Japanese confidant. 
This book is part of the Modern War Studies series.

American Command of the Sea examines the development of Allied code breaking expertise, the role of signal intelligence in the global war at sea in the 1940s, and the ways in which the modern American navy has been shaped by the experience of World War II. This books draws on recently declassified documents to show that many Allied naval victories hinged on the work of a small, multinational group of Allied code breakers. World War II forever changed the nature of naval warfare. Aircraft carriers and submarines, in particular, were used to devastating effect against Axis forces in both the Atlantic and the Pacific, ultimately tilting the conflict in favor of the Allies. As American Command of the Sea explains, the effectiveness of these two types of warships was greatly enhanced by communications or signal intelligence.

American Command of the Sea Through Carriers, Codes, and the Silent Service (Mariners' Museum publication)

Mariners' Museum

When first published in 1995, this book was hailed as an absolutely indispensable contribution to the history of the Pacific War. Drawing heavily from Japanese sources and American wartime intercepts of secret Japanese radio messages, a noted American naval historian and a Japanese mariner painstakingly recorded and evaluated a diverse array of material about Japan's submarines in World War II. 
The study begins with the development of the first Japanese 103-ton Holland-type submergible craft in 1905 and continues through the 1945 surrender of the largest submarine in the world at the time, the 5300-ton I-400 class that carried three airplanes. Submarine weapons, equipment, personnel, and shore support systems are discussed first in the context of Japanese naval preparations for war and later during the war. Both successes and missed opportunities are analyzed in operations ranging from the California coast through the Pacific and Indian Oceans to the coast of German-occupied France. Appendixes include lists of Japanese submarine losses and the biographies of key Japanese submarine officers. Rare illustrations and specifically commissioned operational maps enhance the text.

The fact that Japanese submarines were relatively ineffective in World War II, particularly when compared with those of the Americans and Germans, has long been acknowledged, but the reasons cited for their shortcomings have been varied and based on limited information. Now, a noted American naval historian and a Japanese mariner have painstakingly recorded and evaluated a diverse array of material - much of it only recently declassified - and drawn authoritative new conclusions. The focus of their examination is American wartime intercepts of secret Japanese radio messages and official Japanese sources. This study reaches back to the development of the first Japanese 103-ton Holland-type submersible craft in 1905 and continues through the 1945 surrender of the largest submarine in the world, the 5,300-ton I-400 that carried three airplanes. Submarine weapons, equipment, personnel, and shore support systems are discussed first in the context of Japanese naval preparations for war, and later during the attrition of war. The authors fully analyze a series of successes and missed opportunities in submarine operations in the Pacific, Indian, and Atlantic Oceans, from the California coast to German-occupied France. The appendixes include lists of Japanese submarine losses and biographies of key submarine officers with the rank of lieutenant commander and above. Nineteen rare illustrations and fourteen specially commissioned operational maps enhance the text. Specialists and World War II submarine buffs alike will appreciate the efforts undertaken by these two men.
