After the surrender of Poulcres, the duke returned to Courtray, and left his army to live on the country, where the men at arms did innumerable mischiefs; for he had not money sufficient to pay them until his revenues were paid, and he had borrowed as much as he could from the rich merchants and burghers of his territories, the war having totally exhausted his treasury. He resided at Courtray twelve days,--and during that time his finances were recruited, and he paid his army one month in advance; so that, on the 16th day of July, he departed from Courtray to besiege the castle of Gaveren, which was strongly fortified and held by the ghent men. It is situated between Ghent and Oudenarde. In marching thither, he formed his army into three battalions. The marshal of Burgundy, as commander in chief, sir Anthony the bastard, the lord de Chimay bailiff of Hainault, with a numerous company of men at arms and archers, led the van. In the center was the duke, the most fearless, courageous, and gallant of men: with him were his son the count de Charolois, the count d'Estampes, sir Adolphus of Cleves, and almost all the knights and esquires of Picardy. In the rear division were sir James de St Pol, the lord de l'Isle-Adam, and the whole chivalry of the Boulonois. This army was in truth very strong; and there was need that it should be so, for the men of Ghent had boasted, that this time, they would fairly meet the duke in battle. When they learnt that the duke intended to besiege Gaveren, they sent thither an Englishman, called John de Voz, a very able man at arms, with sixteen others, and swore to him, on his departure, that the duke should not remain four-and-twenty hours unfought with. Nevertheless, the duke's army posted themselves around the place,--and the batteries were erected without any molestation. There was at this time in the place a trumpeter, who had formerly served one of the lords in the duke's army, but had turned to the ghent men: he mounted the highest rampart,--and, having sounded his trumpet as loudly as he could, he abused the duke in the grossest manner, calling him a tyrant, and threatening him that the men of Ghent would soon lower his pride. The duke, when told of this, like a good prince, laughed at it, and turned the trumpeter's folly into ridicule.
