"The Japanese bombers appeared over Chungking on moon-lit nights when they could easily see the major landmarks... from time to time, on command of their formation leader, all the bombers would open up a defensive barrage of fire in direction most likely of attack by fighters. The performance was effective. It was like a gigantic broom of fire sweeping the starry sky."
