In the beginning of this year, the fortress of Malmaison, situated two leagues from the castle of Cambresis, belonging to Jean de Lens, lord of Liéequerque and bishop of Cambray, in right of his bishoprick, was surprised by sir John Blondel of king Charles's party, accompanied by a few men. The governor for the bishop was a fair esquire, called Walter de Baillon, whom they caught in bed. Sir John Blondel having traversed the ditches, though full of water, scaled the walls by means of ladders, and entering the lower court, seized the guard, and his troops posted themselves in ambuscade near the bridge of the dungeon. In the morning, when the porter lowered the drawbridge, they rushed upon him with drawn swords, and put him to death; after which, they entered without further opposition, although it was the strongest of all the forts in that country. The adjacent parts were greatly alarmed at this conquest, even those within the castle of Cambresis; and the bishop of Cambray, being then there, was much surprised how and by whom it could have been taken, for at that time the whole country was at peace. The bishop, however, sent some of his people, and the inhabitants of Cambresis to Malmaison, to learn who had done this, and by what means. On their arrival, they had a parley with those who had taken it; but they, through mischief, replied by shouting the war-cries of Burgundy and Luxembourg, and those who had come thither returned to Château Cambresis. Sir John Blondel having soon provided himself with provision, stores, and men in abundance, began to make inroads on the country of Cambresis, and the parts adjoining, committing irreparable injuries, and in some of these he was joined by parties attached to the duke of Burgundy and sir John de Luxembourg. In the mean time, the bishop sent to the duke of Burgundy, to know if it had been with his consent that his castle had been taken. The duke replied, that so far from having consented, he would send him such assistance that his castle should be restored to him. Some time after the decease of duke John of Brabant, a grand assembly of the nobility was held at Valenciennes, at which were present the duke of Burgundy, the counts de Namur, de Penthievre, and de Conversan, the prince of Orange, sir John de Luxembourg, the bishops of Tournay and of Arras, with many other churchmen, to consider who was to have the government of Hainault. After long and mature deliberation, it was resolved it should remain in the hands of the duke of Burgundy, who in consequence nominated various officers for the due government thereof. In this year, the earl of Warwick and other Englishmen besieged the town of Pontorson, and forced the garrison to surrender on capitulation, provided they were not relieved by a certain day, and that the French and Bretons should not be sufficiently strong to conquer the English. As they were not relieved, the place was surrendered according to the terms of the capitulation.
