When all these lords above-mentioned, and many others, were come to Arras, the king of France advanced to a small river, which is about three leagues distant from Tournay. It was very deep, and the country about it so marshy, that it could be not crossed, but by a very narrow causeway, on which two men would have difficulty to pass abreast. The king and his army encamped in the fields, as they could not cross this river. The next day they remained there also; and the lords about the king held a council, on the best means of building bridges, to pass over this river and the quagmires in safety. They sent some knights and armed men to examine the passages, who, after having well considered them, reported that it would be pains thrown away, and that there was no other means of crossing this river and country, but by the Pont-à-Tressin. Every thing, therefore, remained as before, and each lord took up his quarters among his own men. The news was soon spread abroad, that the king of France and his army were encamped between the bridges of Tressin and Bouvines, with the intention of giving his enemies battle; so that all men of honour, who were desirous of fame, went and joined one side or other, as pleased them best. Three German knights, who were in garrison at Bouchain, heard, as others had done, that the two kings were near each other, and it was thought they would fight. Upon which two of them urged and entreated their companion that he would consent to remain in Bouchain, to guard and preserve it until they returned, and that they would make an excursion as far as Tournay, to seek adventures, and to see how things were going on.
The two knights set out, whose names were sir Courrat d’Astra and sir Courrat de Lancenuch;2 they rode till they came to Estampons, above Valenciennes, for they were desirous of crossing the Scheld at Condé. Between Fresnes and Estampons they heard a noise, and met many people running away; upon which they spurred their horses, and pushed on towards the place from whence the outcry came, with their whole company. They were altogether about twenty-five lances. They inquired of the first they met the meaning of all the noise and flight: “Oh Lord, gentlemen,” said they, “the soldiers from Mortagne have made an incursion upon us, and have collected a large booty in this neighbourhood, which they are driving to their fortress, together with many prisoners they have taken.” The two knights asked if they could conduct them to the road these soldiers were going? Upon their answering in the affirmative, they pursued the French of Mortagne, and followed these honest men, who showed them a way through the woods, so that they gained ground upon them, near to Nôtre-Dame-aux-Bois. The French were full one hundred and twenty men, and they were driving before them two hundred large, with some peasants, prisoners. Their captain was a knight from Burgundy, called sir John de Frelais, under the orders of the lord of Beaujeu. As soon as the Germans perceived them they set up a loud shout, and rushed on full gallop. The combat was very sharp, for the Burgundy knight made a gallant defence, as well as some of his company, but not all, for several of them betook themselves to flight; but they were so closely pursued by the Germans and peasants of the country, who had armed themselves with stakes, that few escaped death. Sir John de Frelais was taken, and all the booty recaptured and given to the proprietors, who were very thankful to the Germans ever after. The knights then went forwards to Tournay, where they were very well received.
