If a man in the front line of defenders had emptied his revolver before the one behind him had reloaded, he held his place with the sword. "The wall's giving from the pressure!" Dick exclaimed to his father; and the latter put his whistle to his lips, and the sound rang out shrill and high above the uproar. A minute later the front of the wall tottered and fell. Then Major Warrener held up his hand, and Captain Dunlop, who had stood all the time quietly watching him, fired the train. A thundering explosion, a flight of bodies and fragments of bodies through the air, a yell of terror from the enemy, and then, as those already rushing triumphantly through the breach stood paralyzed, the British fell upon them sword in hand; the men from the other walls came rushing up, eager to take their part in the fray, and the enemy inside the gate were either cut down or driven headlong through it! The crowd beyond, already shaken by the murderous fire that the party on the walls kept up unceasingly upon them, while they stood unable to move from the jam in front, had recoiled through their whole mass at the explosion, and the sight of the handful of their comrades flying through the gate completed the effect. With yells of rage and discomfiture, each man turned and fled, while the defenders of the gateway passed out, and joined their fire to that of their comrades above on the flying foe. "Thank God, it is all over!" Major Warrener said; "but it has been hot while it lasted. Have we had many casualties?" The roll was soon called, and it was found that the besieged had escaped marvelously. One young fellow, a civil servant, had been shot through the head, by a stray ball entering the loophole through which he was firing. Thirteen of the defenders of the gateway were wounded with pistol shots, or with sword cuts; but none of the injuries were of a serious character. It was now rapidly becoming dark, and Major Warrener mounted one of the towers to have a last look. The enemy had rallied at a distance from the walls, and two fresh bodies of troops, with elephants, were to be seen approaching from the distance. "That is all right," he said. "They will wait, and renew the attack to-morrow." An hour afterward it was night. The moon had not risen yet, and Major Warrener had a huge bonfire lighted outside the gate, with posts and solid beams from the fallen gates and from the houses. "That will burn for hours," he said, "quite long enough for our purpose."
