Of 10,492 V-1s ultimately fired at Britain, about 4,000 were destroyed by fighters, balloons, and antiaircraft guns, while others veered off course or crashed prematurely. But about 2,400 hit greater London, killing 6,000 and badly injuring 18,000. (Not one struck Tower Bridge.) It was, an official British history concluded, “an ordeal perhaps as trying to Londoners as any they had endured throughout the war.”
