At break of day the moat was filled, and the wooden tower began to move on its wheels towards a part of the curtain on which two catapults were already playing to breach the hoards, and clear the way. There was something awful and magical in its approach without visible agency, for it was driven by internal rollers worked by leverage. On the top was a platform, where stood the first assailing party protected in front by the drawbridge of the turret, which stood vertical till lowered on to the wall; but better protected by full suits of armour. The beseiged slung at the tower, and struck it often, but in vain. It was well defended with mattresses and hides, and presently was at the edge of the moat. The knight bade fire the mine underneath it. Then the Turkish engine flung a stone of half a hundredweight right amongst the knights, and carried two away with it off the tower on to the plain. One lay and writhed: the other neither moved nor spake. And now the besieging catapults flung blazing tar-barrels, and fired the hoards on both sides, and the assailants ran up the ladders behind the tower, and lowered the drawbridge on to the battered curtain, while the catapults in concert flung tar-barrels and fired the adjoining works to dislodge the defenders. The armed men on the platform sprang on the bridge, led by Baldwyn. The invulnerable knight and his men-at-arms met them, and a fearful combat ensued, in which many a figure was seen to fall headlong down off the narrow bridge. But fresh besiegers kept swarming up behind the tower, and the besieged were driven off the bridge. Another minute, and the town was taken; but so well had the firing of the mine been timed, that just at this instant the underpinners gave way, and the tower suddenly sank away from the walls, tearing the drawbridge clear and pouring the soldiers off it against the masonry, and on to the dry moat. The besieged uttered a fierce shout, and in a moment surrounded Baldwyn and his fellows; but strange to say, offered them quarter. While a party disarmed and disposed of these, others fired the turret in fifty places with a sort of hand grenades. At this work who so busy as the tall knight. He put the fire-bags on his long spear, and thrust them into the doomed structure late so terrible. To do this he was obliged to stand on a projecting beam of the shattered hoard, holding on by the hand of a pikeman to steady himself. This provoked Denys; he ran out from his mantelet, hoping to escape notice in the confusion, and levelling his crossbow missed the knight clean, but sent his bolt into the brain of the pikeman, and the tall knight fell heavily from the wall, lance and all. Denys gazed wonder-struck; and in that unlucky moment, suddenly he felt his arm hot, then cold, and there was an English arrow skewering it.
