The besieged often made sallies from two and even three gates within an hour's time, and on these occasions, as it was afterwards known, they gained more than they lost; for, during the siege, they brought into the place upward of twelve score prisoners, and great numbers were in these sallies always left dead on the field.
One particular skirmish took place near the river Scarpe, between the suburbs of Belle-mocte and the postern of Arras, which was very fatal to the besiegers. A party from the vanguard had crossed the river on a plank, one at a time, to the number of six or seven score, purposing to make an attack on the postern; but the besieged instantly sallied forth to combat them, and drove them back to the plank,--when they, finding they could not repass without much danger, rallied and forced their enemies to retreat to the postern. At length by the valour of a man at arms, called Perceval le Grand, who was the leader of the townsmen, they were again forced to the water's edge, and so vigorously attacked that fifty at least were killed on the spot, or made prisoners: from fifteen to twenty were drowned in attempting to cross the river, whose bodies, in armour, were dragged out on the following day.
About twenty of the besieged were killed or taken in their various sallies. Among those of name made prisoners were Baugeois de la Beauvriere, the bastard de Belle, the Bastard Dembrine, and some other gentlemen from Burgundy; but they lost the greater part of their best horses in these skirmishes.
The castle of Belle-mocte, situated near to Arras, remained, during the siege, steady to the Burgundy party. The guard of it was given to sir Fleurant d'Ancre and sir Symon de Behaignon: with them was a man at arms called Jean Rose, who was strongly suspected of wishing to betray the castle for money,--and on that account was made prisoner and his effects confiscated. This fortress was well defended by the said knights, for the duke of Burgundy, although the king's army took great pains to conquer it.
To speak of all the different expeditions and incursions the king's troops made during this siege into Artois, Ternois, and other parts, would make too long a narrative; but I shall notice that which took effect under one of the bastards of Bourbon, and other captains, with about one thousand combatants. They went on a foraging party into the county of St Pol, from which they gained an immense booty, in peasants, horses, cattle, sheep, and other things: they even advanced to the town of St Pol, in which were count Waleran, styling himself constable of France, and the countess his wife, sister to the duke of Bar. They treated count Waleran with much abusive language, and said that he only pretended to be ill, to avoid serving the king, his sovereign lord; and that he had manifested his warm affection to the duke of Burgundy by sending his nephew sir John de Luxembourg, with the greater part of his vassals, to assist him.
