At this moment the signal for the general assault was given, from the other side of the town, by an arrow tipped with lighted tow being shot straight up into the air; and in a moment the whole plain rang with the shouts and cries of the attack and defence.
Arthur could not resist the desire to ride round for a moment, and see the progress of the besiegers in other points; and animated with the sight of the growing strife, the clanging of the trumpets, and the war-cries of the combatants, his very heart burned to join his hand in the fray, and win at least some part of the honour of the day. De Coucy, however, was his only hope in this respect; and galloping back as fast as he could, after having gazed for a moment at the progress of each of the other parties, he approached so near the point where the knight was carrying on his operations, that the arrows from the wall began to ring against his armour. Arthur's heart beat joyfully at the very feeling that he was in the battle; but a sight now attracted his attention, which engrossed all his hopes and fears, in anxiety for the noble knight who was there labouring in his behalf.
The masses of wall which De Coucy and his followers had detached, had left so large a gap in the solid foundation of the tower, that it became necessary to support it with the large piles of wood, to prevent the whole structure from crushing them beneath its fall, while they pursued their labours. This had just been done, and De Coucy was still clearing away more of the wall, when suddenly a knight, who seemed to have been informed of what was passing, appeared on the battlements of the tower, followed by a number of stout yeomen, pushing along an immense instrument of wood, somewhat like one of the cranes used in loading and unloading vessels. From a high lever above, hung down the whole trunk of a large tree, tipped at the end with iron; this was brought immediately over the spot where De Coucy's mantlet concealed himself and his followers from the lesser weapons of the besieged, and, at a sign from the knight, the lever slowly raised the immense engine in the air.
"Have a care!--have a care! Sire de Coucy!" shouted at once the whole troop of Brabançois, as well as Arthur's men-at-arms. But before their cry could well reach the knight, or be understood, the lever was suddenly loosed, and the ponderous mass of wood fell with its iron-shod point upon the mantlet, dashing it to pieces. Hugo de Barre was struck down, with four of the other squires; but De Coucy himself, who was actually in the mine he had dug, with three more of his followers, who were close to the wall, remained untouched. Hugo, however, instantly sprang upon his feet again, but little injured, and three of his companions followed his example; the fourth remained upon the field for ever.
"Back, Hugo!--Back to the prince, all of you!" cried De Coucy.--"Give me the light, and back!"
The squires obeyed; and, having placed in the knight's hand a resin torch which was by this time nearly burnt out, they retreated towards the Brabançois, under a shower of arrows from the walls, which, sped from a good English bow, in more than one instance pierced the lighter armour of De Coucy's squires, and left marks that remained till death. In the mean while, not a point of De Coucy's armour, as he moved to and fro at the foot of the tower, that was not the mark of an arrow or a quarrel; while the English knight above, animated his men to every exertion, to prevent him from completing what he had begun.
"A thousand crowns to him who strikes him down!" cried he.--"Villains! cast the stones upon him! On your lives, let him not fire those fagots, or the tower and the town is lost.--Give me an arblast;" and as he spoke, the knight snatched a cross-bow from one of the yeomen, dressed the quarrel in it, and aimed steadily at the bars of De Coucy's helmet as he bore forward another bundle of fagots and jammed it into the mine.
The missile struck against one of the bars, and bounded off. "Well aimed, William of Salisbury!" cried De Coucy, looking up. "For ancient love, my old companion in arms, I tell thee to get back from the tower, for within three minutes it is down!" And so saying, he applied his torch to various parts of the pile of wood he had heaped up in the breach, and retired slowly towards prince Arthur, with the arrows rattling upon his armour like a heavy shower of hail upon some well-roofed building.
"Now, my noble lord," cried he, "down from your horse, and prepare to rush on! By Heaven's grace, you shall be the first man in Mirebeau; for I hear by the shouts, that the others have not forced the gates yet.--Hugo, if thou art not badly hurt with that arrow, range the men behind us--By the Lord! William of Salisbury will stay till the tower falls!--See! they are trying to extinguish the fire by casting water over, but it is in vain; the pillars have caught the flame. Hark, how they crack!"
As De Coucy spoke, the earl of Salisbury and his men, seeing that the attempt to put out the fire was useless, retired from the tower. The flame gradually consumed the heaps of loose wood and fagots with which the knight had filled the mine; and the strong props of wood with which he had supported the wall as he worked on, caught fire, one after the other, and blazed with intense fury. The besiegers and the besieged watched alike in breathless expectation, as the fire wore away the strength of the wood. Suddenly one of the props gave way; but only a mass of heated masonry followed. Another broke--the tower tottered--the others snapped short with the weight--the falling mass seemed to balance itself in the air, and struggle, like an overthrown king, to stand for but a moment longer--then down it rushed, with a sound like thunder, and lay a mass of smoking ruins on the plain.
