aug 6, 1945 - Hiroshima is bombed
The uranium gun-type atomic bomb that was dropped on Hiroshima had an explosive blast equal to approximately 12-15,000 tons of TNT, incinerating five square miles of the city surrounding the Aioi Bridge. At the time of the bombing, Hiroshima was home to 280,000-290,000 civilians as well as 43,000 soldiers. About 80,000 were killed instantly or seriously wounded. Between 90,000 and 166,000 people are believed to have died from the bomb in the four-month period following the explosion. The U.S. Department of Energy has estimated that after five years there were perhaps 200,000 or more fatalities as a result of the bombing, while the city of Hiroshima has estimated that 237,000 people were killed directly or indirectly by the bomb's effects, including burns, radiation sickness, and cancer. Of the estimated 90,000 buildings, 62,000 were destroyed, including the elimination of all utilities and means of transportation.
