Hiroshima

Although the bomb Little Boy was ready for use on August 2, 1945, bad weather delayed dropping it over Japan. At 8:15 on the morning of August 6, 1945, a large portion of the city of Hiroshima was destroyed when Little Boy was dropped. Of a population of 256,000, approximately 70,000 people died immediately. Approximately half of the city had been leveled.
