This Guy could well understand, for although the guns could not be depressed sufficiently to fire down into the _tête du pont_, the mangonels were hurling stones into it, and the men-at-arms shooting cross-bow quarrels whenever a man showed himself. The rear of the outwork was open and afforded no shelter to those who had taken possession of it, and already the greater portion had retired to the other side of the small moat surrounding it, where they lay sheltered by the outwork itself. It was not long before the assailants at the other points, finding that the plan they had formed was defeated by the skill of the archers, poured down in a mass between the two lines of mantlets, each man carrying his burden before him, thus sheltering him to a great extent. Against this method of attack the archers could do little, and now confined themselves to shooting at the men who, having thrown down the fascines or sacks by the edge of the moat, stood for a moment and hesitated before running back to the shelter of the mantlets, and not one in three got off scot-free. Guy on going round the wall found the same state of things at each of the other three points of assault. Numbers of the enemy were falling, but great piles of materials were accumulating at the edge of the moat. After a time a number of knights and men-at-arms, fully protected by armour, came down and began to hurl the sacks and bags into the moat, their operations being covered as much as possible by a storm of missiles shot through holes in the mantlets. In a short time Sir Eustace ordered the archers to desist shooting, for they were obliged, in order to aim at those so much below them, to expose a considerable portion of their bodies, and three were killed by the enemy's missiles.
