The prince of Wales, at the breaking of the daie was readie in the field with his people arranged in order of battell, and aduanced forward with them toward his enimies, an hosting pace; and as they passed a little hill, they might sée as they were descending downe the same, their enemies comming likewise towards them, in good order of battell. When they were approached néere togither, and readie to ioine, the duke of Lancasters battell incountered with the battell of sir Berthram de Cleaquin, which two battels verie eagerlie assailed each other so that there was betwixt them a sore conflict, and well continued. The erle Dom Teille, and his brother the lord Sanches, upon the first approach of the princes battell towards them, fled out of the field, and with them two thousand speares, so that the residue of their battell were shortlie after discomfited, for the capitall of Buz otherwise Beuf, and the lord Clisson, came vpon them on foot, and slue and hurt manie of them, so that they brake their arraie, and fled to saue themselues.
This chance discomforted the hearts of the Spaniards right sore, but yet king Henrie like a valiant gentleman came forward, and incouraged his men all that he might, so that there was a cruell battell, and well foughten a long time. For the Spaniards with slings cast stones in such fierce manner, that they claue therewith manie an helmet and bassenet, hurt manie, and ouerthrew them to the earth. On the other part, the English archers shot freshlie at their enemies, galled and slue the Spaniards, and brought them to great confusion: yet king Henrie nothing abashed herewith, wheresoeuer he perceiued his men to shrinke, thither he resorted, calling upon them, and exhorting them to remember their estimations and duties, so that by his diligence and manfull incouragement, thrise that daie did he staie his people, being at point to giue ouer; and set them in the faces of his enemies againe. Neither did the souldiers alone manfullie behaue themselues, but the capteins also stoutlie laid about them. King Peter like a lion pressed forward, coueting to méet with his brother Henrie, that he might séeke his reuenge on him with his owne hands. Cruell was the fight, and tried throughlie with most eger and fierce minds.
