Those within the castle repaired what damage had been done, for they had plenty of workmen. On the morrow the French resolved to divide their army into four divisions, the first of which should make an attack on this fortress from the dawn until about nine o’clock; the second, from that time until noon; the third, from noon till four o’clock; and the fourth division, from that time till night. This mode of attack was continued for six successive days. However, those within the castle were never so much harassed but that they could defend themselves valiantly; and their enemies gained nothing but the bridge which was before the castle. The French lords, upon this, held a council, and sent to Toulouse for eight of their largest battering-engines, and constructed four other large ones upon the spot. These twelve engines cast stones into the fortress day and night; but the besieged had taken such pains to avoid what mischief they could do, that they only destroyed the roofs of the houses. They had also made counter-engines, which played upon those of their enemies, and in a short space of time totally ruined six of them.
During this siege Sir Walter Manny made frequent excursions beyond the river, with about sixscore companions, to forage, and often returned with his booty in sight of the army. One day the Lord Charles of Montmorency had been on a foraging party, with five or six hundred men, and was conducting a great number of cattle to victual the army, when he met Sir Walter Manny under the walls of Aiguillon. They immediately began an engagement, which was very sharp, and many were killed and wounded on both sides. The French were at least five to one. News was brought of this into Aiguillon, when every one sallied out for the fastest, and the Earl of Pembroke with the foremost; they dashed into the midst of them, and found Sir Walter Manny unhorsed, and surrounded by his enemies, but fighting most valiantly. He was directly rescued and remounted. During the heat of the engagement, the French hastened to drive off the cattle to a place of safety, or they would have lost them; for the English were coming in crowds to succor their countrymen, and, falling upon the French vigorously, they put them to flight, rescued those they had made prisoners, and captured also many from them. The Lord Charles de Montmorency had great difficulty to escape, and retreated as fast as he could, quite discomfited. When it was over, the English returned to Aiguillon.
