During these tribulations, there were so many grievous complaints made to the king and the princes at Paris, of the mischiefs done to the country by the garrisons of Estampes and Dourdan, that notwithstanding it had been determined in council that neither the king nor the duke of Acquitaine should take the field until the winter should be passed, this resolution was overruled by circumstances. On the 23d day of November, the duke of Acquitaine, accompanied by the duke of Burgundy, the counts of Nevers, de la Marche, de Penthievre, de Vaudemont, and the marshal de Boucicaut, with others of rank, and a great multitude of the Parisians on foot, marched out of Paris, with the intent to reduce to the king’s obedience the garrisons of Estampes and Dourdan, and some others, who continued the war on the part of the duke of Orleans and his adherents. He halted at Corbeil to wait for the whole of his forces,--and thence, with an immense quantity of warlike stores and bombards, with other artillery, marched his army toward Estampes, wherein was sir Louis de Bourdon, who instantly withdrew into the castle. The townsmen immediately returned to their former obedience, and were kindly received by the duke of Acquitaine, in consideration of his uncle the duke of Berry. Sir Louis de Bourdon, however, refused to surrender, although he was summoned many times, when the castle was besieged on all sides. The lord de Ront was at this time prisoner there,--for he had been taken by sir Louis not long before the arrival of the duke of Acquitaine. Many engines were now pointed against the walls, which they damaged in several places; and in addition, miners were employed to underwork the towers. The siege was carried on with such vigour that the garrison, thinking it probable they should be taken by storm, opened a parley, and, by means of the lord de Ront, surrendered themselves to the duke of Acquitaine. Sir Louis de Bourdon, with some other gentlemen, his confederates, were sent to the Châtelet at Paris. Great part of the wealth of Bourdon, with a most excellent courser of his, were given to the lord de Ront, to make amends for the losses which he sustained when he was made prisoner. The dukes of Acquitaine and Burgundy re-garrisoned this place, and then returned with their army to Paris; for in truth, they could not, from the severity of the winter, make any further progress. A few days after, by order of the duke of Burgundy, many noble prisoners were carried from Paris to the castle of Lille; among whom were the lord de Hangest, sir Louis de Bourdon, the lords de Gerennes, des Fontaines, sir John d’Amboise and others, who had been arrested for supporting the party of the duke of Orleans. They suffered a long confinement, but were set at liberty on paying a heavy fine.
