Atomic bombings of Hiroshima and Nagasaki
Events on the ground. Although the bomb was more powerful than the one used on Hiroshima, the effect was confined by hillsides to the narrow Urakami Valley. Of 7,500 Japanese employees who worked inside the Mitsubishi Munitions plant, including mobilized students and regular workers, 6,200 were killed. Some 17,000–22,000 others who worked in other war plants and factories in the city died as well. Casualty estimates for immediate deaths range from 40,000 to 75,000. Total deaths by the end of 1945 may have reached 80,000. Unlike Hiroshima's military death toll, only 150 soldiers were killed instantly, including thirty-six from the IJA 134th AAA Regiment of the 4th AAA Division. At least eight known POWs died from the bombing and as many as 13 may have died, including a British citizen, Royal Air Force Corporal Ronald Shaw, and seven Dutch POWs. One American POW, Joe Kieyoomia, was in Nagasaki at the time of the bombing but survived, reportedly having been shielded from the effects of the bomb by the concrete walls of his cell. There were 24 Australian POWs in Nagasaki, all of whom survived. The radius of total destruction was about , followed by fires across the northern portion of the city to south of the bomb. About 58% of the Mitsubishi Arms Plant was damaged, and about 78% of the Mitsubishi Steel Works. The Mitsubishi Electric Works only suffered 10% structural damage as it was on the border of the main destruction zone. The Mitsubishi-Urakami Ordnance Works, the factory that manufactured the type 91 torpedoes released in the attack on Pearl Harbor, was destroyed in the blast.
