Hirohito's imprisonment and Anami's refusal to surrender cause US President Harry Truman to order Army Chief of Staff General George Marshall to begin preparations for Operation Downfall, the invasion of the Japanese home islands. The atomic bombing campaign of Japanese cities is continued, as is done when a third atomic bomb is dropped on Kokura, which completely destroys the city. Because of this, Anami authorizes the transfer of Allied prisoners-of-war to cities that have strategic importance, which forces the Americans to suspend the atomic bombing campaign until further notice. The OSS recruit the Japanese American veteran Joe Nomura to head into Nagasaki under the guise of a Japanese officer to investigate the effects of the atomic bombing.
