Marching Orders tells the story of how the American military's breaking of the Japanese diplomatic Purple codes during World War II led to the defeat of Nazi Germany and hastened the end of the devastating conflict. With unprecedented access to over one million pages of US Army documents and thousands of pages of top-secret messages dispatched to Tokyo from the Japanese embassy in Berlin, author Bruce Lee offers a series of fascinating revelations about pivotal moments in the war.



Challenging conventional wisdom, Marching Orders demonstrates how an American invasion of Japan would have resulted in massive casualties for both forces. Lee presents a thrilling day-by-day chronicle of the difficult choices faced by the American military brain trust and how, aware of Japan's adamant refusal to surrender, the United States made the fateful decision to drop nuclear bombs on Hiroshima and Nagasaki.



Hailed as 'one of the most important books ever published on World War II' by Robert T. Crowley, Marching Orders unveils the untold stories behind some of the Second World War's most critical events, bringing them to vivid life. It's a story that, as historian Robin W. Winks said, 'no one with the slightest interest in World War II or in the origins of the Cold War can afford to ignore.'
