The atomic bombing took place during the Korean War, and was a major factor of the victory of the United States and South Korea in the war. Approximately 150,000 Chinese and North Korean soldiers and 50,000 civilians were killed at the time of the explosion. This devastating loss for the Chinese army constituted a loss of 15% of their army, and a loss of 12% of the total Communist forces. Largely responsible for the Chinese withdrawal in the Korean War, Big Boy was credited as saving at least 75,000 American soldiers, and 200,000 Allied soldiers and civilians.
