MacArthur's Ultra: Codebreaking and the War Against Japan, 1942-1945 (Revised) (Modern War Studies) - Tapa blanda

"No one writing on military operations in the Southwest Pacific will be able to ignore this book."--William M. Leary, editor of We Shall Return: MacArthur's Commanders and the Defeat of Japan, 1941-1945"Adds significantly to our understanding of the war and of MacArthur as commander and strategist."--Stanley L. Falk, author of Bataan: The March of Death "A 'must' item for analysis of the Pacific war."--Harold Deutsch, author of Hitler and His Generals "A must for anyone with more than a superficial interest in World War II or military history. This is the first comprehensive examination of General Douglas MacArthur's use of ULTRA. Drea's use of primary sources and secondary Japanese material results in a balanced picture that gives both sides of the story. Particularly fascinating is his description of the Japanese codes themselves and how they were decoded by MacArthur's Central Bureau."--Choice"Drea's excellent study presents a detailed illustration of the interplay between intelligence-gathering and operational planning and uses one of history's most successful commanders as its model."--Publishers Weekly "A superb book that will surely be the prime reference work on the subject for years to come."--Cryptologia "Belongs in all War II collections."--Library Journal "One of the preeminent historians of the Pacific War, Drea has produced a groundbreaking assessment of the impact of 'special intelligence' (i.e., ULTRA intercepts) on MacArthur's Southwest Pacific Area campaigns that is vital to those hoping to gain a full understanding in this corner of the war. An outstanding book."--Armchair General

It took the US army two full years after the attack on Pearl Harbour to break the radio codes of the Japanese Imperial Army. But by 1944, the US was decoding more than 20,000 messages a month filled with information about enemy movements, strategy, fortifications, troop strengths and supply convoys. In MacArthur's ULTRA, historian Edward Drea recounts the story behind the army's painstaking operation and its dramatic breakthrough. He demonstrates how ULTRA (intelligence from decrypted Japanese radio communications) shaped MacArthur's operations in New Guinea and the Philippines. By correlating the existing intelligence with MacArthur's operational decisions, Drea shows how MacArthur used - and misused - intelligence information. He also clarifies the role of ULTRA in Truman's decision to drop atomic bombs on Japan in 1945, and examines the role of ULTRA on the outcome of World War II.
