On 6 August 1945, a bomb nicknamed Little Boy was dropped by the US B-29 warplane Enola Gay and obliterated the city of Hiroshima, killing 140,000 out of an estimated population of 350,000, with thousands more dying later of illness and injuries. Three days after the Hiroshima attack, on 9 August 1945, the United States dropped another atomic bomb on Nagasaki, southern Japan.
