Some knights bachelors from Hainault joined them; among whom were Sir Florent de Beaurieu, Sir Latas de la Haye (marshal of the army), the Lord John of Hainault, Sir Oulphart de Guistelles, Sir Robert Glewes from the county of Los (at that time only a squire), and many more; amounting altogether to upward of three hundred good men at arms. They came to Pont-à-Tressin, which they crossed without loss. They then held a council, on what would be the most advantageous plan for them to beat up and skirmish with the army of the French. It was determined that the Lord of Rauderondenc, and his son, Sir Henry de Kalkren, a mercenary knight, Sir Thilman de Saussy, Sir Oulphart de Guistelles, Sir l’Alleman of Hainault, Sir Robert Glewes, and Jacquelot de Thiaulx, should act as light-horse, and skirmish up to the tents of the French; that the rest of the knights and squires, who might amount to three hundred, should remain at the bridge to keep and defend that pass in case of any attack. This advanced body then set out: they were forty persons altogether, well mounted upon handsome and strong chargers. They rode on till they came to the French camp, when they immediately dashed in, and began to cut down tents and pavilions, and do every possible damage by skirmishing with all that opposed them. That night two great barons, the Lord of Montmorency and the Lord of Saulieu, had the watch, and were with their guard when the Germans fell upon them. As soon as they heard the noise, they and their banners moved toward it.
