The duke of Yorke, perceiuing that the French king minded not to fight, purposed to passe ouer the riuer of Oise, and so to fight with him in his lodging. Whervpon he remooued his campe, and appointed the lord Talbot and other, to make a countenance, as they would passe the riuer by force at the port of Beaumont: and appointed an other companie in boates of timber and leather, and bridges made of cords and ropes (whereof he had great plentie caried with him in chariots) to passe ouer beneath the abbie. Whilest the lord Talbot made a crie, as though he would assault the gate, certeine Englishmen passed the water in botes, and drew a bridge of cords ouer, so that a great number of them were got to the other side, yer the Frenchmen were aduised what had happened. When they saw the chance, they ran like mad men, to haue stopped the passage, but it was too late: for the most part of the Englishmen were got ouer, in so much that they chased their enimies backe, and slue sir Guilliam de Chastell, nephue to the lord Taneguie du Chastell, and diuerse others. [Sidenote: _Enguerant de Monstrellet._] [Sidenote: _Edw. Hall._] The Frenchmen séeing their euill hap irrecouerable, returned to the French king, and told him what had chanced: wherevpon he doubting to be assailed to his disaduantage, thought not good longer to tarrie, but with all spéed remoouing his ordinance into the bastile of saint Martin, which he had newlie made, dislodged in the night from Maubuisson, and went to Poissie, leauing the lord de Cotignie admerall of France, with thrée thousand men to kéepe the bastile. If he had taried still at Maubuisson, the lord Talbot which had passed the riuer of Oise in two small leather botes, had either taken or slaine him the same night. The Englishmen the next daie in good order of battell came before the towne of Ponthoise, thinking there to haue found the French king, but he was gone: and in his lodging they found great riches, and much stuffe which he could not haue space for to carrie awaie for feare of the sudden inuasion.
