In that shower of death it seemed preposterous that any of the hundred and sixty-eight could have escaped, for the trench mortar was of very large caliber. But the fragments had barely ceased screaming when men again populated the clearing. A swift survey showed that only a kettle and a pack had suffered and the latter but slightly. "Tou-tou!" said the lieutenant. "Take cover in that passage mouth to cover us." "Yess, yess, mon lieutenant." "Double file, follow me!" cried the lieutenant, striding to the top of the largest entrance of the fortress. At the top he paused. "All right. Quickly. Down with you." And he passed his hurrying men by him and below with a gesture. A shrill piping, growing stronger, again cleared the place as though by magic. The three-pounder blazed out and shrapnel again hammered the wood. But the men were up and hurrying through its smoke before branches had ceased to fall. "Pollard!" said the lieutenant. "Yessir," replied the sergeant major. "Give a hand. Get down below there, Malcolm. We're all right. All below, now." With the sergeant's help, the lieutenant began to pile the dry brush upon the fire. Mawkey, in the entrance, yelped, "Mortar!" It burst almost on the fire. The lieutenant and Pollard slipped out from behind cover and completed the piling of the brush. Then, with the boxes supported between them, they began to empty two hundred pounds of assorted and cast-off bullets through the brush pile. An old device it was, almost as old as cartridges themselves but oldest things are often the surest. "Shell!" howled Mawkey. The piping ended in a roaring flash. The top of a tree leaned slowly over and then plummeted to earth. The lieutenant, up again, pulled the glass visor of his Italian helmet down over his face and wrapped his cloak tightly about him. "Get down with our people there!" he shouted to Pollard. The sergeant was reluctant, but he obeyed. By now, because of the pauses caused by the shells, a few of the cartridges were beginning to explode in the brush pile. Slugs occasionally made the silk cloak whip up about the skirt. The lieutenant emptied the last box and dived down into the entrance.
