Long before his death, President Roosevelt had been making plans to ensure an Allied victory in the war. He had never discussed these arrangements with Vice President Harry Truman. Only after Truman was sworn in as president in April, 1945 did Secretary of War Henry Stimson tell him about the Manhattan Project. The Manhattan Project was the code name for the government's top-secret attempt to build an atomic bomb. It was given that name because much of the early research was done in Manhattan. American, British, and European scientists worked feverishly to develop the powerful new weapon. They feared that Germany would develop its own bomb first. In 1944, however, U.S. Intelligence agents discovered that Germany had abandoned its atomic bomb program at an early stage. Nevertheless, the Manhattan Project scientists continued their work. In April, 1945 Secretary Stimson told Truman that the bomb probably would be ready

Nothing seemed to go right on this mission. Before takeoff, the pilot, Captain Charles W. Sweeney, learned that a fuel pump on the plane was not working. This meant there would not be any reserve fuel for the return flight. Nearly halfway to Japan, a signal light alerted weapons expert Commander Frederick Ashworth that "Fat Man's" safety plugs had failed. For the next half hour, he and his assistant checked the wiring. It turned out to be a false alarm. Then, the camera plane failed to meet up with Bock's Car and the instrument plane. The bomber could not call the missing plane because the Japanese would hear the message. After a forty-minute search, they had to go on without the camera plane. The delay cost precious fuel. At 10:44 A.M., the B-29 arrived over the target city of Kokura. Bock's Car made three unsuccessful bombing runs because the aiming point remained hidden under heavy ground smoke and haze. The B-29 then decided to make a run down to Nagasaki, as there was no sense bringing the bomb home or dropping it in the ocean.

After the bombing of Hiroshima, The U.S. government announced that it had a terrible new weapon. The Air Force dropped leaflets over major Japanese cities and broadcast radio messages to the Japanese people. They were told to ask their government to end the war. Otherwise, they would be destroyed like the people of Hiroshima. Once more, Japanese diplomats appealed to the Soviet Union to help them secure a peace settlement. On August 8, the Soviet Union replied by declaring war on Japan. Joseph Stalin sent troops to seize nearby Manchuria, which Japan had conquered earlier. According to Truman's orders, a second atomic bomb would be detonated unless Japan surrendered. Bad weather conditions were forecast for the target cities after August 10, so the bomb had to be dropped immediately. At 3:47 A.M. on August 9, a B-29 bomber named Bock's Car left Tinian with "Fat Man" in its bomb bay. This bomb looked like a giant egg with fins. It was more advanced and complicated than "Little Boy". It had to be armed before takeoff, although safety plugs were in place.

At 2:45 in the morning, August 6, 1945, the Enola Gay, a B-29 Bomber, took off on a secret mission
