It was 6th August, 1945 when a US, B-29 dropped the world’s first Atomic bomb named “Little Boy” on the city of Hiroshima which killed almost 80,000 people directly as a result of the impact of the blast while another 35,000 were injured and at least another 60,000 would be dead by the year’s end.
U.S. President Harry S. Truman, after being discouraged by the Japanese response to the Potsdam Conference’s demand for unconditional surrender, made the decision to use the atom bomb to end the war in order to prevent what he predicted would be a much greater loss of life were the United States to invade the Japanese mainland.
On August 9 Major Charles Sweeney flew another B-29 bomber, Bockscar, from Tinian. Thick clouds over the primary target, the city of Kokura, drove Sweeney to a secondary target, Nagasaki, where the plutonium bomb “Fat Man” was dropped at 11:02 that morning.
August 15, 1945 at noon on (Japanese time), Emperor Hirohito announced his country’s surrender in a radio broadcast. The news spread quickly, and the United States and other Allied nations clebrated “Victory in Japan” or “V-J Day”.
