This book was released on 2012-06-28 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: For historians and many members of the informed public, the Japanese attack on Hawaii provoked "the never-ending story." Multiple official investigations and private historical inquiries into the attack and its background have generated enormous stocks of information about both the American and Japanese sides. It may well be that we know as much about December 7, 1941, as we do about any event in the last century, the Kennedy assassination possibly excepted. However, even with this virtual mountain chain of data, information gaps still exist, and many important questions remain under discussion or debate. The discussions and debates are not simply the province of conspiracy buffs. Academics and other researchers interested in World War II have a serious stake in settling the issues of the U.S.-Japan conflict; definite answers to many of the controversies would either confirm or refute theories of the war's origins and its meaning. This assemblage of documents, supplemented by the author's clear guide to their meaning, places the reader, as it were, right in the middle of the behind-the-scenes events and helps the scholar and researcher to follow them closely.

Download or read book Hoax written by Edward Steers and published by University Press of Kentucky. This book was released on 2013-04-01 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: A “lively yet thoroughly researched” look at persistent myths and stubborn scams, and how historians try to combat them (The Courier-Journal). Did a collector with a knack for making sensational discoveries really find the first document ever printed in America? Did Hitler actually pen a revealing set of diaries? Has Jesus’ burial cloth survived the ages? Can the shocking true account of Abraham Lincoln’s assassination be found in lost pages from his murderer’s diary? Napoleon famously observed that “history is a set of lies agreed upon,” and Edward Steers Jr. investigates six of the most amazing frauds ever to gain wide acceptance in this engrossing book. Hoax examines the legitimacy of the Shroud of Turin, perhaps the most hotly debated relic in all of Christianity, and the fossils purported to confirm humanity’s “missing link,” the Piltdown Man. Steers also discusses two remarkable forgeries, the Hitler diaries and the “Oath of a Freeman,” and famous conspiracy theories alleging that Franklin D. Roosevelt had prior knowledge of the planned attack on Pearl Harbor and that the details of Lincoln’s assassination are recorded in missing pages from John Wilkes Booth’s journal. The controversies that Steers presents show that there are two major factors involved in the success of a hoax or forgery—greed and the desire to believe. Though all of the counterfeits and conspiracies featured in Hoax have been scientifically debunked, some remain fixed in many people’s minds as truth. As Steers points out, the success of these frauds highlights a disturbing fact: If true history fails to entertain the public, it is likely to be ignored or forgotten.

Download or read book West Wind Clear written by Robert J. Hanyok and published by www.Militarybookshop.CompanyUK. This book was released on 2011-01-01 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Did the American Government and President Franklin Delano Roosevelt have advance information about Japan s attack on Pearl Harbor and was this fact later suppressed, either to conceal incompetence or because the President wanted an act of aggression to force America into war with the Axis Powers? For decades, professional and amateur historians alike have scrutinized the voluminous and sometimes contradictory trail of evidence surrounding this historic and tragic event to find an answer.One of the most written-about pieces of this historical puzzle is the so-called West Wind Execute message, Japan s code phrase to advise its diplomats abroad that an attack on America was imminent. In West Wind Clear: Cryptology and the Winds Message Controversy a Documentary History, the U.S. National Security Agency s Center for Cryptologic History has tackled the complex history of this message, when it was sent, and why its existence or non-existence has exercised the imaginations of academics, amateur historians, and conspiracy buffs since the 1940s. Crucially, this book includes many key documents, some never before published, dealing with the voluminous Japanese signals traffic leading up to the Pearl Harbor attack and the timing of signals interception and decoding.The authors state that the main source of continuing debate over the who knew and when question resulted from a number of contradictory statements by a well-respected American cryptographer, Captain Laurence Safford, USN, whose reliability as a witness was undermined during the hearings of the 1946 Joint Congressional Committee investigation of the Pearl Harbor debacle. Despite these findings, the West Wind controversy has persisted in popular accounts that lent credibility to the stories of Safford and Ralph Briggs, a radio operator who many years after the fact claimed to recollect a West Wind Execute message before the attack. West Wind Clear makes a strong and well-documented case against a suppressed warning of war, although perhaps no account of the run-up to the Pearl Harbor debacle may ever lay to rest the many conspiracy theories bruited about since 1941. For anyone interested in the continuing debate, this book is an indispensable research and reference work.

Download or read book Code Breaking in the Pacific written by Peter Donovan and published by Springer. This book was released on 2014-08-14 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reveals the historical context and the evolution of the technically complex Allied Signals Intelligence (Sigint) activity against Japan from 1920 to 1945. It traces the all-important genesis and development of the cryptanalytic techniques used to break the main Japanese Navy code (JN-25) and the Japanese Army’s Water Transport Code during WWII. This is the first book to describe, explain and analyze the code breaking techniques developed and used to provide this intelligence, thus closing the sole remaining gap in the published accounts of the Pacific War. The authors also explore the organization of cryptographic teams and issues of security, censorship, and leaks. Correcting gaps in previous research, this book illustrates how Sigint remained crucial to Allied planning throughout the war. It helped direct the advance to the Philippines from New Guinea, the sea battles and the submarine onslaught on merchant shipping. Written by well-known authorities on the history of cryptography and mathematics, Code Breaking in the Pacific is designed for cryptologists, mathematicians and researchers working in communications security. Advanced-level students interested in cryptology, the history of the Pacific War, mathematics or the history of computing will also find this book a valuable resource.

Download or read book Joe Rochefort s War written by Elliot W Carlson and published by Naval Institute Press. This book was released on 2013-09-15 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elliot Carlson’s award-winning biography of Capt. Joe Rochefort is the first to be written about the officer who headed Station Hypo, the U.S. Navy’s signals monitoring and cryptographic intelligence unit at Pearl Harbor, and who broke the Japanese navy’s code before the Battle of Midway. The book brings Rochefort to life as the irreverent, fiercely independent, and consequential officer that he was. Readers share his frustrations as he searches in vain for Yamamoto’s fleet prior to the Japanese attack on Pearl Harbor, but share his joy when he succeeds in tracking the fleet in early 1942 and breaks the code that leads Rochefort to believe Yamamoto’s invasion target is Midway. His conclusions, bitterly opposed by some top Navy brass, are credited with making the U.S. victory possible and helping to change the course of the war. The author tells the story of how opponents in Washington forced Rochefort’s removal from Station Hypo and denied him the Distinguished Service Medal recommended by Admiral Nimitz. In capturing the interplay of policy and personality and the role played by politics at the highest levels of the Navy, Carlson reveals a side of the intelligence community seldom seen by outsiders. For a full understanding of the man, Carlson examines Rochefort’s love-hate relationship with cryptanalysis, his adventure-filled years in the 1930s as the right-hand man to the Commander in Chief of the U.S. Fleet, and his return to codebreaking in mid-1941 as the officer in charge of Station Hypo. He traces Rochefort’s career from his enlistment in 1918 to his posting in Washington as head of the Navy’s codebreaking desk at age twenty-five, and beyond. In many ways a reinterpretation of Rochefort, the book makes clear the key role his codebreaking played in the outcome of Midway and the legacy he left of reporting actionable intelligence directly to the fleet. An epilogue describes efforts waged by Rochefort’s colleagues to obtain the medal denied him in 1942—a drive that finally paid off in 1986 when the medal was awarded posthumously.

This book was released on 2020-03-03 with total page 784 pages. Available in PDF, EPUB and Kindle. Book excerpt: “A sweeping epic.… Promises to do for the war in the Pacific what Rick Atkinson did for Europe.” —James M. Scott, author of Rampage In 1937, the swath of the globe east from India to the Pacific Ocean encompassed half the world’s population. Japan’s onslaught into China that year unleashed a tidal wave of events that fundamentally transformed this region and killed about twenty-five million people. This extraordinary World War II narrative vividly portrays the battles across this entire region and links those struggles on many levels with their profound twenty-first-century legacies. In this first volume of a trilogy, award-winning historian Richard B. Frank draws on rich archival research and recently discovered documentary evidence to tell an epic story that gave birth to the world we live in now.

Download or read book U S Navy Codebreakers Linguists and Intelligence Officers against Japan 1910 1941 written by Steven E. Maffeo and published by Rowman & Littlefield. This book was released on 2015-12-16 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique reference presents 59 biographies of people who were key to the sea services being reasonably prepared to fight the Japanese Empire when the Second World War broke out, and whose advanced work proved crucial. These intelligence pioneers invented techniques, procedures, and equipment from scratch, not only allowing the United States to hold its own in the Pacific despite the loss of most of its Fleet at Pearl Harbor, but also laying the foundation of today’s intelligence methods and agencies. One-hundred years ago, in what was clearly an unsophisticated pre-information era, naval intelligence (and foreign intelligence in general) existed in rudimentary forms almost incomprehensible to us today. Founded in 1882, the U.S. Office of Naval Intelligence (ONI)—the modern world’s “oldest continuously operating intelligence agency”—functioned for at least its first forty years with low manning, small budgets, low priority, and no prestige. The navy’s early steps into communications intelligence (COMINT), which included activities such as radio interception, radio traffic analysis, and cryptology, came with the 1916 establishment of the Code and Signals Section within the navy’s Division of Communications and with the 1924 creation of the “Research Desk” as part of the Section. Like ONI, this COMINT organization suffered from low budgets, manning, priority, and prestige. The dictionary focuses on these pioneers, many of whom went on, even after World War II, to important positions in the Navy, the State Department, the Armed Forces Security Agency, the National Security Agency, and the Central Intelligence Agency. It reveals the work and innovations of well and lesser-known individuals who created the foundations of today’s intelligence apparatus and analysis.

Download or read book The War Below written by James Scott and published by Simon and Schuster. This book was released on 2013-05-14 with total page 563 pages. Available in PDF, EPUB and Kindle. Book excerpt: A “beautifully researched and masterfully told” account of the US submarine force that helped win World War II in the Pacific (New York Times–bestselling author Alex Kershaw). Focusing on the unique stories of three of the war’s top submarines—Silversides, Drum, and Tang—The War Below vividly re-creates the camaraderie, exhilaration, and fear of the brave volunteers who took the fight to the enemy’s coastline in World War II. Award-winning journalist James Scott recounts incredible feats of courage—from an emergency appendectomy performed with kitchen utensils to sailors’ desperate struggle to escape from a flooded submarine—as well as moments of unimaginable tragedy, including an attack on an unmarked enemy freighter carrying 1,800 American prisoners of war. Facing devastating odds—a submarine crewman was six times more likely to die than a sailor onboard a surface ship—these brave men accomplished their mission: Silversides, Drum, and Tang sank a combined sixty-two freighters, tankers, and transports. In retaliation, the Japanese often beat, tortured, and starved captured submariners in the atrocious prisoner of war camps. Based on more than 100 interviews with submarine veterans and thousands of pages of previously unpublished letters and diaries, The War Below lets readers experience the battle for the Pacific as never before.

Download or read book Historical Dictionary of World War II written by Anne Sharp Wells and published by Rowman & Littlefield. This book was released on 2023-12-15 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: World War II was the largest and most costly conflict in history, the first true global war. Fought on land, on sea, and in the air, it involved numerous countries and killed, maimed, or displaced millions of people, both civilian and military, around the world. In spite of the alliances that bound many of the same participants, the war was essentially two separate but simultaneous conflicts: one involved Japan as the major antagonist and took place mostly in Asia and the Pacific; and the other, initiated by Germany and Italy, was contested mainly in Europe, North Africa, the Mediterranean, and the Atlantic. This book focuses on the lesser known war, the war with Japan. It begins with Japan’s seizure of Manchuria from China in 1931 and covers Japan’s ambitious attacks on Pearl Harbor and other territories ten years later, the use of atomic bombs on Japan’s cities, and the end of the Allied occupation of Japan in 1952. Although Japan renounced war in its 1947 constitution, conflict continued across Asia, as former colonies fought for independence and civil war engulfed other areas. Historical Dictionary of World War II: The War Against Japan, Second Edition contains a chronology, an introduction, and an extensive bibliography. The dictionary section has more than 500 cross-referenced entries on the military, diplomatic, political, social, economic, and scientific aspects of the war, in addition to the lives of the people who participated in and directed the war. This book is an excellent resource for students, researchers, and anyone wanting to know more about the war against Japan during World War II.

Download or read book British Naval Intelligence through the Twentieth Century written by Andrew Boyd and published by Seaforth Publishing. This book was released on 2020-08-30 with total page 757 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2021-10-24 with total page 823 pages. Available in PDF, EPUB and Kindle. Book excerpt: On 7 December 1941, Washington sent a message to its Pacific outposts about a potential Japanese attack. All but Pearl Harbor received it in time to prepare. New information from the archives of George Street, District Manager of RCA-Honolulu, exposes the fatal flaws that resulted in the surprise attack. Operational snafus, collusion, and spies weave a web of misdirection that entangles George Street and his children in one of history's biggest mistakes. Pearl Harbor's Final Warning amends the historical record by presenting previously unpublished material, including the original copy of General Marshall's coded message.

Download or read book Intelligence and Surprise Attack written by Erik J. Dahl and published by Georgetown University Press. This book was released on 2013-07-19 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
