The inhabitants also wanted to prevent the canons selling wine from their cellars, although they had for a long time done so from their own vintage. For these several offences and grievances, the canons having frequently demanded, but in vain, redress from the townsmen, made heavy complaints of what they had suffered, and were still suffering, to the duke of Burgundy and his council, because, as earl of Flanders, he was the hereditary guardian and defender of all the churches within Cambray. For this guardianship a certain quantity of corn was annually paid to the duke, as protector of the churches within the Cambresis, and this impost was called the Gavenne[28] of Cambresis. The duke of Burgundy was very much displeased at this conduct of the Cambresians, and sent solemn messengers to inform them, that if they did not make instant and full satisfaction to the canons who were under his protection, for all the damages they had done them, he should take such measures as would serve for an example to all others. Not receiving an answer which was agreeable to him, and being then in Burgundy, he wrote to his son, Philippe count de Charolois, in Flanders, to order him to secure the canons of St Gery from all oppression and violence, and to constrain the inhabitants of Cambray to make reparation for the wrongs they had done them. The count of Charolois, knowing the temper of his father, again summoned the townsmen to make satisfaction to the canons; and because they sent evasive answers, he secretly advised the canons to leave Cambray and go to Lille, at which town he would find them a handsome dwelling. The canons, on this, placed the better part of their effects, in safety, and then secretly left Cambray and went to Lille, or at least the greater number of them. Soon after their departure, the count de Charolois sent his defiance to the town of Cambray by Hector de Saveuses, who had assembled full three hundred combatants. On the feast-day of the exaltation of the holy cross, he suddenly entered the Cambresis, and advanced almost to the gates of Cambray, when, it being market-day, he plundered, killed and wounded very many of the town, and perpetrated other cruel deeds. Hector did not make any long stay, but departed, with an immense booty, to quarter himself near to Braye-sur-Somme, saying, that what he had done was by orders from the count de Charolois. This attack much astonished those of Cambray, and put them in great fear. They conceived a greater hatred than before against the canons of St Gery, increased every preparation for the defence of their town, and made daily seizures of the effects of these canons, such as wine, corn, wood and other necessaries of life.
