Although the place was unfavourably situated for the batteries to have their full effect, they alarmed the garrison so much that they offered to surrender on having their lives spared, seeing also that the ghent men did not fulfil their promises when they left that town; but the duke refused their offer. When the Englishman heard this, and found that the men of Ghent had deceived him, it is said that he had a communication with some of the English in the duke's army, and promised to deliver up to them one of the towers of the castle; but this he could not accomplish,--for the ghent men had no confidence in him, nor in any of the English. A vessel happened to be lying in the river, near to the castle, and during the night John de Voz, and fourteen others, embarked on board and went to Ghent. When those in Gaveren saw the next morning that their captain had deserted them, they abandoned all hope of succour, and surrendered themselves to the duke's will before twelve of the clock. His will was that they should be all hanged or strangled, together with two cordelier friars that were in the place, and the trumpeter who had abused the duke. John de Voz and his companions, on their arrival in Ghent, remonstrated sharply with the leaders in the town, how greatly they had deceived those in Gaveren, and how weakly they had acted; for they never would again have so favourable an opportunity of combating the duke, since he had not now with him more than four thousand fighting men, the rest having disbanded from want of pay; and he concluded by exhorting them strongly to sally forth and offer the duke battle. In the mean time, sir John de Hout, an Englishman, who had surrendered himself to sir Anthony the bastard, as I have mentioned, had a secret communication with the duke, on the means of enticing the ghent men out of their town, for he was extremely anxious to meet their whole force in the field. Soon afterward, John de Hout returned to Ghent, under pretence of repenting of his having left them, and told them that the duke's army was daily wasting away from default of payment. The men of Ghent, however, doubting his fidelity, ordered him to prison, lest he should betray them: he was there confined until John de Voz had pressed them so earnestly to attack the duke, with their whole force, when they released him and made him one of their captains. They commanded all the gates to be kept closed, that no one might carry to the duke information of their intentions, and gave orders that every person capable of bearing arms should provide himself, and appear properly armed and accoutred, under pain of death. It was necessary for all to obey this order, or suffer the consequences; but many did obey very much against their will.
