On the quiet morning of August 6, 1945, the United States shocked the world by dropping an atomic bomb over the city of Hiroshima, Japan. Hiroshima was a major industrial city with an estimated population of almost 400,000 people. A B-29 bomber was loaded with the Atomic Bomb and left the United States Pacific air base at around 2: 45 a.m. local time and dropped the bomb at around 8: 15 a.m. The bomb was detonated one minute after being dropped. The atomic bomb, nicknamed 'Little Boy', which was dropped on the Hiroshima City, exploded at an altitude of 580 meters above surface.

The mushroom cloud resulting from the explosion reached an estimated altitude of five hundred and twenty meters over Central Hiroshima. The fireball resulting from the explosion emitted an intense thermal heat, which caused severe burns and loss of eyesight. Most of the people exposed to thermal rays died. In addition, the impact of the bomb landing on the ground created an enormous shock wave closely followed a quick expansion of air.

The result was the immediate death of about 75,000 people. Atomic blasts cause many prolonged injuries such as leukemia and other cancers. The total death count for the atomic bombing is estimated at 140,000. Americans believed that the Japanese would fight until the very last man even if there were a dropping of the atomic bomb.

Luckily for them the war ended. The reason the United states dropped the atomic bomb was because they wanted the unconditional surrender of Japan. Many innocent people died because of tension between two governments. On December 7th, 1945, Japan bombed Pearl Harbor while the shipment were going through their normal Sunday routines. The United States would soon retaliate by dropping an atomic bomb over Hiroshima on the morning of August 6th, 1945.
