At length, the besieged seeing all their efforts vain, and hopeless of succour, concluded a treaty with sir John, by his commissioners, on the 18th day of January, to surrender the place, on condition that they should depart in safety, with their baggage, and with a part of what they had gained in the town. When this treaty was ratified, the Dauphinois marched away under passports from sir John de Luxembourg, who appointed Hector de Saveuses to escort them; and, when out of the town, they took the road to Compiegne, marching with great speed. Very soon after their departure, about two thousand English came to Roye, under the command of the earl of Huntingdon, and his father-in law sir John de Cornwall,[4] to assist the Burgundians; for, as I have said, there was a truce between the English and them, expecting that this truce would shortly be (as it happened) turned into a solid peace. The English, hearing of the departure of the Dauphinois, hastily set out in pursuit of them, and overtook them about four leagues from Roye. The moment they came near, without any words, they attacked them lance in hand, although they were few in number; for, having rode so hard, three parts of their men were behind. The English were accompanied by many of the men at arms of sir John de Luxembourg, the principal of whom were Butor bastard of Croy, Aubellet de Folleville, the bailiff de Foquesolle, the bastard Dunon and several other gentlemen. The Dauphinois made no great resistance, and were therefore soon routed, very many were killed, taken or robbed; but a few escaped as well as they could, by flying to the woods and other places. Hector de Saveuses, observing this, made sir Karados de Quesnes his prisoner, in order to save him and restore him to liberty; but sir John de Cornwall took him from him, saying that he had not any right to make him his prisoner, since he had a passport from his captain; and because Hector would not release him at the first word, Cornwall smote him severely on the arm with his gauntlet, which incensed Hector much,--but he could not help himself; as the English were too numerous. Sir Karados, the lord of Flavy, and the most part of the men at arms were made prisoners by the English; but those taken by the Picards were put to death by them, for they were afraid to bring them to their quarters on account of the passports that had been granted them. However, Harbonniers, who was prisoner to Aubellet de Folleville, was carried to Noyon, and there beheaded.
