In Matthew Parker (allegedly of nosy parker fame) was born; in 1806 the Holy Roman Empire formally came to an end; in 1943 the "god of the internet" was born; in 1962 Jamaica became independent from the UK and in 1991 the paper was released describing the WWW. In 1945 the first atomic bomb was used on Hiroshima.

In 1945 "Little Boy" was dropped on Hiroshima

In 1945 Hiroshima had a population of between 300,000 and 350,000 people, not including the soldiers who were present. There were a number of important military units including the headquarters from where the defence of southern Japan was being managed along with being a key supply and logistics base for the military.


On the 6th of August, 1945, the B-29 Enola Gay started its 6 hour journey to Hiroshima, accompanied by two other B-29s. It was at 8:09am that the bomb run was started and at 8:15am Little Boy was released. It contained 64kg of uranium-235 and took 44.4 seconds to fall from the bomber, detonating about 580m above the city.

Atomic Explosion over Hiroshima

It was blown off-course and detonated above the Shima Surgical Clinic, releasing approximately 16 kilotons of TNT, resulting in total destruction over an area of almost 2km and fires going through an area of 11km2.

Approximately 70,000 to 80,000 people were killed by the blast with more being injured. It was estimated that about 70% of the buildings were destroyed. There had been an air raid warning prior to the bomb being dropped on the city, however this was stopped at 7:30am with the result being people on the streets going about their business.


US President Truman issued a statement announcing the new weapon and that more would follow if Japan did not accept the terms. With no indication that Japan would do as such a second bomb was dropped on Nagasaki on the 9th of August. The Japanese surrendered on the 14th of August.

The Hiroshima Peace Memorial Museum includes the Genbaku Dome which serves as a memorial to the over 140,000 people who were killed.
