On the 6th and 9th of August, 1945, US B-29 bombers dropped two atomic bombs on Hiroshima and Nagasaki.

It had been about 3 years and 8 months since the Japanese first bombed United States naval, Pearl Harbour.

The United States had remained a neutral party during World War II until the bombing of Pearl Harbour.

The bombing of Hiroshima and Nagasaki was a decisive move in ending the Japanese Occupation of Southeast Asia.

By this time, the Japanese forces had lost their will to continue the war and allowed Allied forces to send in reinforcements and food supplies.

Prisoners-of-war were checked by the medical officers and arrangements were made to send them home.

On August 15, 1945, Japan announced their surrender.

The formal signing of the surrender instrument was held at the City Hall, then known as the "Municipal Hall", on September 12, 1945.

This was followed by a celebration at the Padang, which included a victory parade.
