Main Events

9 Aug 1945 Atomic bombing of Nagasaki ▲

On 9 August 1945, the Boeing B-29 bomber Bockscar, piloted by Maj. Charles W. Sweeney, departed Tinian intending to drop a second atomic bomb nicknamed “Fat Man” on Kokura, Japan. Fuel problems led the crew to instead drop the bomb on their secondary target, Nagasaki, at 11:01 AM. in wikipedia

9–20 Aug 1945 Soviet invasion of Manchuria ▲

In the Manchurian Strategic Offensive Operation, over 1.5 million Soviet troops invaded the Japanese puppet states of Manchukuo and Mengjiang on three fronts from positions in the Soviet Far East and the Mongolian People’s Republic. The scale, speed, and directions of the attack caught the 700 thousand strong Japanese Kwantung Army by surprise, with the Soviet pincers, supported by airborne units, penetrating deep into Manchuria. Despite this, Japanese resistance continued until 20 August—five days after Emperor Hirohito’s surrender broadcast—by which time the Soviets had reached the key cities of Mukden, Changchun, and Qiqihar. in wikipedia

From 16 August, the Soviets began landing along the coast, seizing the ports of Toro (Shakhtyorsk), Esutoru (Uglegorsk), and Maoka (Kholmsk). A final Soviet landing at the capital of Otomari (Korsakov) on 25 August forced the main Japanese garrison to surrender, bringing an end to resistance. in wikipedia
