After months of bombing cities in Japan, the US issued an ultimatum called the Potsdam Declaration of July 26, 1945 demanding that Japan surrender. The Japanese government ignored this demand. The US dropped the first atomic bomb on Hiroshima on August 6; then the second on Nagasaki on August 9. On August 15, Japan announced its surrender and on September 2, 1945 Japan signed an Instrument of Surrender, officially ending the war.
The US's official justification was that it would save many more lives than it cost by ending the war, but most people just wanted the war to end period. The secondary goal was to let it be known that it would be much too costly in lives to wage war in the future and hoped that the atomic bomb would be the ultimate deterrent.

The men who worked on the Manhattan Project (The scientific effort behind the weapon that started years before) began the project from fear that the Germans were building one. After they realized what they had created when they tested one in New Mexico, they hoped that the terror of the atomic weapon would be the end to all wars. Unfortunately, The USSR didn't think that way, and by 1950, you have a desperate race for missile production between the US and Russia.
Today, the Nuclear Missile is the most feared weapon of all. If they start flying, the world will turn into a fallout mess. The men of the Manhattan project quivered at what they created when they tested it. One man put it this way:
We knew the world would not be the same. A few people laughed, a few people cried, most people were silent. I remembered the line from the Hindu scripture, the Bhagavad-Gita. Vishnu is trying to persuade the Prince that he should do his duty and to impress him takes on his multi-armed form and says, "Now, I am become Death, the destroyer of worlds." I suppose we all felt that one way or another.

Can you tell us when the Hiroshima Battle you are referring to occurred? There was none in World War 2. Bombing runs are not considered battles, and there was basically no Hiroshima at the end of the war.
