Eight days afterward, the count d'Armagnac, who had been sent for by the council, arrived at Paris to receive the investiture of his constableship, by receiving from the king the sword of constable, and taking the usual solemn oaths. He thanked the king for the high honour he had conferred on him. The new constable had now a force of six thousand combatants at least, including those whom he found in Paris, and very shortly dispatched Raymonnet de la Guerre with four hundred helmets to garrison St Denis, and defend it against any attack from the duke of Burgundy. He strengthened in like manner other towns on the Seine, and had all the bridges and ferries destroyed. The king, at this period, filled up the vacant offices caused by the misfortune at Azincourt, and appointed Jean de Corssay, a native of Berry, master of the cross-bows of France; sir Thomas de Lersies, bailiff of the Vermandois, and the lord de Humbercourt, bailiff of Amiens; the lord d'Aunay, a native of la Rochelle, to the same office at Senlis; sir Mansart d'Asne, bailiff of Vitry, and sir Brunet de Bans to the same at Tournay, with very many others. CHAP. XXXVII. THE DUKE OF BRITTANY ARRIVES AT PARIS. THE DUKE OF BURGUNDY LEAVES LAGNY SUR MARNE.--THE CAPTURE OF SIR MARTELET DU MESNIL AND FERRY DE MAILLY. The duke of Brittany at this time came to Paris to treat with the king, that the duke of Burgundy with his army might march into Brittany, but he was unsuccessful. Before he departed from Paris, he was violently enraged against sir Taneguy du Châtel, provost of Paris, and abused him much, because he had imprisoned in the Châtelet the minister of the Mathurins, a doctor of theology, for having, in his presence, harangued the populace in favour of the duke of Burgundy. In a few days, however, he gave him his free liberty. When the duke of Burgundy had remained at Lagny sur Marne six weeks without having been able to prevail on the king and his council to permit him to enter Paris any otherwise than in his simple state, he marched away to Dampmartin, thence toward Rheims, and through the Laonnois, Tierrache and Cambresis, to the town of Douay, and thence to Lille. He was, all the time, accompanied by a strong body of men at arms, who much oppressed the poor people on their march. On his departure from Lagny, some of the king's soldiers advanced to Pont à Vaire, and slew and made prisoners many of his men, at which he was highly displeased. From his long residence at Lagny, the Parisians, and others attached to the king, called him, in common conversation, Jean de Lagny. After some short stay at Lille, he went to visit his nephews in Brabant, namely, John and Philip, sons to the late duke Anthony of Brabant, taking with him Philippe Maisne, by whom he governed that country. He appointed officers to those places in the counties of Ligny and St Pol, that had been formerly held by count Waleran de St Pol, maternal grandfather to these children.
