Hiroshima and Nagasaki
President Harry S. Truman approved bombing Japan using atomic weapons in 1945. Little Boy exploded over Hiroshima on August 6, and Fat Man was detonated over Nagasaki three days later. Both cities were decimated. World War II ended four days later when Japan surrendered on August 13, 1945. It is difficult to determine how many died or were injured. By the end of 1946, estimates exceeded 250,000 deaths and untold numbers were injured from the initial explosions, radiation poisoning, and other injuries.
