World war II chronology - August 1945

2 August 1945The Potsdam Agreement is signed.
4 August 1945August 6 is set as the date for dropping the first atomic bomb weapon in war, against Hiroshima, Japan. Little Boy is loaded into B-29 Superfortress No. 82.

In Canada, the Prime Minister tells the House of Commons that no act of subversion or sabotage had been found before or during the war by the Japanese Canadians. However, disloyal Japanese Canadians would be deported to Japan, and no further Japanese immigration would be allowed. Also, a set quota of dispersed Japanese Canadians would be allowed to return to the west coast of British Columbia.
5 August 1945B-29 Superfortress No. 82, carrying an atomic bomb for use on Japan, is renamed Enola Gay, after the pilot's mother.
6 August 1945The B-29 plane Enola Gay takes off from Tinian island in the Marianas islands, piloted by Colonel Paul Tibbets, carrying an uranium atomic bomb.

One of three American planes flying over Hiroshima, Japan, drops three parachutes carrying blast-recording equipment. American Colonel Paul Tibbets and the crew of the Enola Gay flying at 31,600 feet altitude, drop a 4400 kg uranium-based atomic bomb over Hiroshima, Japan, set to detonate at 1850 feet above the city. The blast has the impact of a 500-mph wind, leveling almost everything within a two-mile radius, destroying 70,000 buildings, sixty percent of the city. 70,000 are killed, and 80,000 wounded. The atomic bomb becomes the largest man-made explosion in history, and largest single killer in history. (By the end of the year, a further 60,000 have died from burns, wounds, and radiation sickness.)
