He was recalled from his dream by the flash of light at his control board and a voice from the radiophone "... to all units," came the message. "Railroad battery 14 about to fire on enemy tanks in Waterford. Request observation for corrections ... General Stanhope to all units. Railroad battery 14, twelve-inch guns, about to fire on enemy tanks in Waterford. Request observation for correction...." "Lieut. Lee, American Tank Corps, to General Stanhope," he called into the phone. "Go ahead with railroad battery 14. Am observing fire from east of town." Even before he had finished speaking there was a dull rumble in the air and a tremendous heave of earth behind and to one side of the shining enemy, not two hundred yards away. "Lieut. Lee to railroad battery 14," he called, delightedly, "two hundred yards over, ten yards right." Berrrroum! Another of the twelve-inch shells fell somewhere ahead of the giants in the village. As Murray shouted the correction one of the metal creatures lifted its snout toward the source of the explosion curiously and as if it had not quite understood its meaning, fired a light-beam at it. Another shell fell, just to one side. A wild hope surging in him, he called the corrections--these were heavier guns than any that had yet taken a hand. "Lieut. Lee, American Tank Corps, to railroad battery 14--Suggest you use armor-piercing shell. Enemy tanks appear to be armored," he called and had the comforting reply. "Check, Lieut. Lee. We are using armor-piercers." Slam! Another of the twelve-inch shells struck, not ten yards behind the enemy. The ground around them rocked; one of them turned as though to examine the burst, the other lifted its snout skyward and released a long, thin beam of blue light, not in the least like the light-ray. It did not seem to occur to either of them that these shells might be dangerous. They seemed merely interested. And then--the breathless watchers in the thickets around the doomed town saw a huge red explosion, a great flower of flame that leaped to the heavens, covered with a cloud of thick smoke, pink in the light of the burning houses, and as it cleared away, there lay one of the monsters on its side, gaping and rent, the mirrored surface scarred across, the phosphorescent glow extinguished, the prehensile snout drooping lifelessly. Murray Lee was conscious of whooping wildly, of dancing out of his tank and joining someone else in an embrace of delight. They were not invincible then. They could be hurt--killed! "Hooray!" he cried, "Hooray!" "That and twelve times over," said his companion. The phrase struck him as familiar; for the first time he looked at his fellow celebrant. It was Gloria. "Why, where in the world did you come from?" he asked. "Where did you? I've been here all the time, ever since Ben ordered us home. Didn't think I'd run out on all the fun, did you? Are those things alive?"
