The return fire from the walls was feeble, and the king said, laughing, "So far your knight, fair mistress, has it all his own way. I did not reckon sufficiently upon the superiority of shooting of the London lads, and, indeed, I know not that I ought not in fairness to order some of the defenders off the walls, seeing that in warfare their numbers would be rapidly thinned. See, the assailants are moving up the two towers under shelter of the fire of the archers." By this time Aylmer, seeing that his followers could make no effectual reply to the arrow fire, had ordered all, save the leaders in full armor, to lie down behind the parapet. The assailants now gathered thickly round each tower, as if they intended to attempt to cross by the bridges, which could be let down from an opening in the tower level with the top of the wall, while archers upon the summit shot fast and thick among the defenders who were gathering to oppose them. "If the young Pembroke is wise," the king said, "he will make a strong sally now and fall upon one or other of the parties." As he spoke there was a sudden movement on the part of the assailants, who, leaving the foot of the towers, made a rush at the outwork in the center. The instant they arrived they fell to work with axes upon the palisades. Many were struck down by the blows dealt them by the defenders, but others caught up the axes and in less than a minute several of the palisades were cut down and the assailants poured in. The defenders fought gallantly, but they were overpowered by numbers. Some were struck down, others taken prisoners by main force, and the rest driven across the drawbridge just as the gates were opened and Pembroke, at the head of the defenders, swarmed out to their assistance. There was a desperate fight on the bridge, and it was well that the armor was stout, and the arms that wielded the weapons had not yet attained their full strength. Several were knocked off the bridge into the moat, and these were, by the rules, obliged at once to retire and take no further part in the contest. Walter and Ralph the smith fought in front of their men, and hard as Pembroke and his followers struggled, they could not drive them back a foot. The court party was galled by the heavy fire of arrows kept up by the apprentices along the side of the moat, and finding all his efforts to regain the earthwork useless, Pembroke withdrew his forces into the castle, and in spite of the efforts of the besiegers managed to close the gates in their faces. The assailants, however, succeeded in severing the chains of the drawbridge before it could be raised.
