The Hiroshima pyre happened on August 6, 1945 at precisely 8:15 a.m. when American B-29 bomber ‘Enola Gay’ released its lethal cargo, the nuclear bomb “Little Boy”. After falling about 48 seconds it exploded at 2000 feet over head unleashing raw nuclear energy equaling about 12-15,000 tons of TNT destroying five square miles of this city and incinerating thousands of its inhabitants alive.
Hiroshima, a militarily significant Japanese city of 350,000 became the first in human history to be nuked and it was not the last to suffer this fate. Today this same city has a population estimated at 1,160,000 give or take a few thousand yet immediately after the bombing the population dropped to a mere 140,000 survivors.
The city was rebuilt after the war when the Japanese national government passed the Hiroshima Peace Memorial City Construction Law in 1949 providing the financial help and extra land previously owned by the government for the reconstruction and development.
The July 16 Trinity Test in New Mexico had exceeded expectations and president Truman gave the OK for atom bombs to be used on Japan. This followed after many attempts to contact and convince the Japanese Imperial government to surrender unconditionally failed.
Some in the American government also entertained the idea of doing a demonstration explosion so that the Japanese could witness to convince them to surrender however, after much discussion they dropped the idea. Most finally agreed that doing this would lead to sacrificing the shock value an atomic bomb attack gave and so all agreed that Japan must be nuked for it to surrender.
The attack resulted in the direct deaths of an estimated 80,000 people instantly after which by the end of 1945, another 170,000 perished from the radiation and blast injuries they suffered.
Interesting, survivors include one man that experienced both Hiroshima and Nagasaki on August 9th living into his 90’s, and a woman who also lived a very long time after. Injured both managed to live long, normal lives because of their luck being protected by the concrete used in the structures they were in while others perished.
