The first bomb was dropped on Hiroshima on August 6, 1945. This bomb killed thousands of people and was very devastating. The name of the plane that dropped the bomb was the Enola Gay and the bomb was given a name as well, Little Boy.

The second bomb, named Fat Man, was dropped on Nagasaki, just three days later on August 9, 1945. Again, tens of thousands of people died. It is said that the bomb dropped on Nagasaki was a lot stronger than the bomb that was dropped on Hiroshima but Nagasaki has a terrain that protected it better from the bomb than Hiroshima did.

The reason for the dropping of the bombs was (most historians say) to end World War II (in the Pacific) as quickly as possible.  Because of that, you should be able to remember that the United States dropped two atomic bombs on Japan in the year 1945.  This was the year in which World War II ended.

The second of these bombs was dropped on today's date (August 9) in that year.  That was the bomb that was dropped on Nagasaki.  The first one was dropped on Hiroshima three days earlier.

The bombs were not used against Germany because they had not actually been made yet by the time that Germany surrendered earlier in 1945.

I always remember them because a friend's birthday is today, the day the second bomb was dropped.  Of course the year was 1945, but I think it is important to add to the previous post because the accepted reason is that it was to end the war with Japan.

But if you read more about the decision that Truman made, it had far more to do with a desire to actually use these weapons that we'd spent billions and billions of dollars developing as well as to send a message to Stalin that we meant business and were not to be trifled with.

Japan was ready to surrender and had made that relatively clear but it needed time to push it through their rather serious bureaucracy.

There have been only two instances of atomic bombs being dropped in a war. Both these bombs were dropped by the US over Japan during the close of World War II in August 1945.

The first bomb was dropped on on Hiroshima on August 6, 1945, This bomb was dropped by a B-29 bomber named Enola Gay. The second bomb was dropped on Nagasaki on August 9, 1945. The bombs killed an estimated 110,000 people immediately. Many others died later, and suffered severe medical complications. In response to dropping of these bombs, Japan agreed to end the war on August 14, 1945, and formally surrendered on September 2, 1945.
