What Day Was the atomic bombing of Nagasaki?

About this date

The United States dropped a second atomic bomb, nicknamed "Fat Man," on the Japanese city of Nagasaki, three days after the first atomic bombing of Hiroshima, killing tens of thousands of people.

Nagasaki was reportedly a secondary target that day, selected only after cloud cover obscured the original primary target city.

Japan's surrender followed within days, and this remains, along with the Hiroshima bombing three days earlier, one of only two instances of nuclear weapons ever used in warfare.

The city's hilly terrain is credited by some historical analyses with limiting the bomb's blast radius compared to Hiroshima's flatter geography, though the death toll and destruction were nonetheless immense.

Nagasaki's status as a major shipbuilding and industrial port city was a significant factor in its selection as a bombing target, alongside military planners' assessment of remaining viable targets late in the war.
