In a day or two the whole of the French army came up, and the siege commenced. Sir John Powis, at his own request, was posted with his men for the defence of a portion of the wall which was especially open to the assaults of the enemy. These soon commenced in earnest, and the Genoese and Spanish mercenaries endeavoured to carry the place by assault. Sometimes one point would be attacked, at others points far distant. Covered by the fire of the French crossbowmen, the Spaniards and Germans came on to the assault, carrying ladders, with which they strove to climb the walls, but the defenders plied them so vigorously with quarrels from their cross-bows and flights of arrows that they frequently desisted before reaching the walls. When they pushed on, and strove to ascend, their luck was no better. Great stones were hurled down, and boiling oil poured upon them. The ladders were flung back, and many crushed by the fall, and in none of the assaults did they gain any footing in the town. Machines were used, but these were not sufficiently powerful to batter down the walls, and at the end of April the city was as far from being captured as it was on the day of the commencement of the siege. Walter bore his full share in the fighting, but he had no opportunity of especially distinguishing himself, although Sir John several times commended him for his coolness when the bolts of the crossbow-men and the stones from the machines were flying most thickly. But although as yet uninjured by the enemy's attacks, the prospect of the city holding out was not bright. The burghers, who had at first fought valiantly, were soon wearied of the strife, and of the hardships it entailed upon them. The siege had continued but a short time when they began to murmur loudly. The force under the command of the governor was but a small one, and it would have been impossible for him to resist the will of the whole population. For a time his exhortations and entreaties were attended with success, and the burghers returned to their positions on the walls; but each time the difficulty became greater, and it was clear to Caddoudal and Sir John Powis that ere long the citizens would surrender the place in spite of them. The English knight was furious at the cowardliness of the citizens, and proposed to the governor to summon twenty of the leading burghers, and to hang them as a lesson to the others; but the governor shook his head. “I have but two hundred men on whom I can rely, including your following, Sir John. We could not keep down the inhabitants for an hour; and were we to try to do so, they would open the gates and let in the French. No; I fear that we must await the end.” The following morning Sir John was awoke with the news that in the night Caddoudal had been seized and thrown into prison by the burghers, and that a deputation of citizens had already gone out through the gate to treat with the Duke of Normandy for the surrender of the city.
