The Atomic Bomb

The atomic bomb, A.K.A. the Manhattan Project, began in 1942 with the help of 100,000 scientists. It was finally tested in New Mexico and ready to go in 1945. The United States at this time was fighting battles in both Europe and the Pacific.

President Harry Truman knew that his Pacific enemy, the Japanese, would not surrender despite numerous attempts of peace. He felt his only option to end this horrible war was to use atomic weapons on Japan.

On August 6, 1945 a B-29 bomber called the Enola Gay dropped the atomic bomb ‘Little Boy’ on Hiroshima, Japan that killed 80,000 people. Three days later, the bomb ‘Fat Man’ was dropped on Nagasaki, killing 40,000 more. Japan finally surrendered to the Allies on August 15. The following months and years saw the deaths of 100,000 people from radiation poisoning, burns, and malnutrition.

That was the only time in history that a nuclear weapon was used during warfare. The repercussions were massive and volatile. We can only hope that a weapon like that will never be used again.
