This is the story of the U.S. Navy's communications intelligence (COMINT) effort between 1924 and 1941. It races the building of a program, under the Director of Naval Communications (OP-20), which extracted both radio and traffic intelligence from foreign military, commercial, and diplomatic communications. It shows the development of a small but remarkable organization (OP-20-G) which, by 1937, could clearly see the military, political, and even the international implications of effective cryptography and successful cryptanalysis at a time when radio communications were passing from infancy to childhood and Navy war planning was restricted to tactical situations. It also illustrates an organization plagues from its inception by shortages in money, manpower, and equipment, total absence of a secure, dedicated communications system, little real support or tasking from higher command authorities, and major imbalances between collection and processing capabilities. It explains how, in 1941, as a result of these problems, compounded by the stresses and exigencies of the time, the effort misplaced its focus from Japanese Navy traffic to Japanese diplomatic messages. Had Navy cryptanalysts been ordered to concentrate on the Japanese naval messages rather than Japanese diplomatic traffic, the United States would have had a much clearer picture of the Japanese military buildup and, with the warning provided by these messages, might have avoided the disaster of Pearl Harbor.
Using previously unreleased documents, the author reveals new evidence that FDR knew the attack on Pearl Harbor was coming and did nothing to prevent it.
Pearl Harbor will long stand out in mens minds as an example of the results of basic unpreparedness of a peace loving nation, of highly efficient treacherous surprise attack and of the resulting unification of America into a single tidal wave of purpose to victory. Therefore, all will be interested in this unique narrative by Admiral Wallin. The Navy has long needed a succinct account of the salvage operations at Pearl Harbor that miraculously resurrected what appeared to be a forever shattered fleet. Admiral Wallin agreed to undertake the job. He was exactly the right man for it _ in talent, in perception, and in experience. He had served intimately with Admiral Nimitz and with Admiral Halsey in the South Pacific, has commanded three different Navy Yards, and was a highly successful Chief of the Bureau of Ships. On 7 December 1941 the then Captain Wallin was serving at Pearl Harbor. He witnessed the events of that shattering and unifying "Day of Infamy." His mind began to race at high speeds at once on the problems and means of getting the broken fleet back into service for its giant task. Unless the United States regained control of the sea, even greater disaster loomed. Without victory at sea, tyranny soon would surely rule all Asia and Europe. In a matter of time it would surely rule the Americas. Captain Wallin salvaged most of the broken Pearl Harbor fleet that went on to figure prominently in the United States Navys victory. So the account he masterfully tells covers what he masterfully accomplished. The United States owes him an unpayable debt for this high service among many others in his long career.
Between 1942 and 1945, the U.S. government wrongfully imprisoned thousands of Japanese American citizens and profited from their labor. Japanese American Incarceration recasts the forced removal and incarceration of approximately 120,000 Japanese Americans during World War II as a history of prison labor and exploitation. Following Franklin Roosevelt's 1942 Executive Order 9066, which called for the exclusion of potentially dangerous groups from military zones along the West Coast, the federal government placed Japanese Americans in makeshift prisons throughout the country. In addition to working on day-to-day operations of the camps, Japanese Americans were coerced into harvesting crops, digging irrigation ditches, paving roads, and building barracks for little to no compensation and often at the behest of privately run businesses—all in the name of national security. How did the U.S. government use incarceration to address labor demands during World War II, and how did imprisoned Japanese Americans respond to the stripping of not only their civil rights, but their labor rights as well? Using a variety of archives and collected oral histories, Japanese American Incarceration uncovers the startling answers to these questions. Stephanie Hinnershitz's timely study connects the government's exploitation of imprisoned Japanese Americans to the history of prison labor in the United States.
