On August 6, 1945, during the Second World War, the first atomic bomb was dropped on the city of Hiroshima in Japan, which was followed by another on August 9 in Nagasaki.
The "Little Boy" bomb was dropped by the B-29 Enola Gay of the United States Air Force. The uranium bomb, with the force of 13,000 TNT, destroyed 70 percent of Hiroshima, creating heat of 3,000 degrees Celsius.
The atomic bomb flattened everything within a radius of 1.5 kilometers, while causing 80,000 deaths in the first phase alone and 140,000 by the end of 1945 from burns and radiation poisoning.
Meanwhile, in Nagasaki, the hills surrounding the city have limited the spread of the destructive force of the 22,000 TNT bomb dropped from a height of 500 meters, however, about 70,000 people have lost their lives in the first phase and half of the city has been destroyed.
The then Emperor of Japan, Michinomiya Hirohito, in his message on August 15 declared his country's unconditional surrender, saying that "the continuation of the war would destroy the Japanese people."
As has been said, Hiroshima was targeted because of military bases, and Nagasaki because of heavy industry. The dropping of the bomb on Nagasaki officially ended the ongoing fighting in the Pacific.
