James M. Scott traces the dramatic, complex final months of World War II in the Pacific. Scott details how Secretary of War Henry Stimson briefed Truman in depth on the secret atomic bomb, and praises General Leslie Groves' masterful management of the Manhattan Project's secret cities. He describes Japan's political division: Emperor Hirohito secretly sought peace while militarists prepared a fanatical defense of Kyushu to force better terms. Scott explains the intense debate over demanding unconditional surrender versus preserving the Japanese monarchy, concluding with the Trinitytest, Potsdam Conference, and Truman's hope that the bomb's shock value would force surrender.
