Nagasaki Before the Attack
Nagasaki on had a population of about 240,000 people, but was mainly a trading city and a center of industry with many ports surrounding it located on the western coast of Kyushu. Nagasaki wasn't initially the target city of the United States instead in was in contention with other cities for the second city for the bombing.
Nagasaki During The Attack
On August 9, 1945, an American B-29 bomber, known as Bock's Car, left carrying "Fat Man", which was a plutonium implosion-type bomb. At 10:58 A.M. Nagasaki Time, the bomb was dropped, and exploded 1,840 feet over Nagasaki. The force it gave off is estimated to be in the vicinity of 22,000 tons of TNT. "Fat Man" exploded stronger at Nagasaki than "Little Boy" did at Hiroshima, but the hills of the city, its geography, and the bomb being detonated over an industrial area helped weaken the impact a bit. The bomb affected around 43 square miles of the city. It is believed that 40,000 people died instantly due to the bomb, while another 60,000 were injured.
Nagasaki After the Attack
It has been stated that without "Fat Man" being dropped on Nagasaki, the Japanese probably would not have surrendered. Nagasaki had 14,000 of its homes destroyed, 5,400 severely damaged, and 12 percent of its homes were unharmed. A day after "Fat Man" brought death and destruction to Nagasaki, the emperor of Japan decided to override any of Japan's military leaders and ordered them to offer to basically surrender.
