On what date in 1945 was Nagasaki struck by the second atomic bomb used in warfare?

Nagasaki was struck by the second atomic bomb used in warfare on August 9, 1945.

The United States dropped the plutonium implosion weapon Fat Man from the B-29 bomber Bockscar. Nagasaki became the target after the primary target, Kokura, was obscured by cloud and smoke. The bombing caused extensive destruction and loss of life, although terrain limited the blast's reach in some areas.

The attack occurred on the same day that Soviet forces began their offensive against Japanese positions in Manchuria. Japan's leaders faced both developments while debating whether to accept the Allied terms.

Nagasaki's bombing preceded Hirohito's surrender broadcast by six days. The later formal surrender ceremony took place aboard USS Missouri on September 2.
