In accordance with his orders, Sir Eustace de Villeroy and Guy were posted close to the king, while John Harpen led the men-at-arms from Summerley. For a time the battle raged fiercely. In the centre fought the king with his nobles and knights; while the archers, who had most of them thrown off their shoes and were able to move lightly over the treacherous ground, threw themselves upon the enemy's flanks, and did dreadful execution there. In the centre, however, the progress of the English was slower. The French knights made the most desperate efforts to attack the king himself, and pressed forward to reach the royal banner. His brother, the Duke of Clarence, was wounded, and would have been killed had not the king himself, with a few of his knights, taken post around him, and kept off the attacks of his foes until he recovered his feet. Almost immediately afterwards a band of eighteen knights, under the banner of the Lord of Croye, who had bound themselves by an oath to take or kill the king, charged down upon him. One of them struck him so heavy a blow on the head with a mace that the king was beaten to his knee, but his knights closed in round him, and every one of his assailants was killed.
