As they advanced the battle grew very hot, and was greatly crowded. Many a one was unhorsed. The battalion of the Duke of Normandy, on seeing the Prince's approach, hastened their flight. The King's three sons, who commanded it, were advised to fly, and galloped away. Many others followed their example, though there were not wanting some brave knights who preferred death to flight. Then the King's battalion advanced in good order. The King and his knights had dismounted. They despaired of the day, but were determined at least to save their honour. Fighting on foot, it was hard to resist the shock of the English men-at-arms; but the King fought with desperate bravery, and by his side fought his little son Philip, a boy of fifteen, who warned his father against unexpected blows. The bravery of the boy on that day earned for him the surname of _le hardi_, the bold. He is that Philip le Hardi afterwards so well known as Duke of Burgundy. King John proved himself a good knight; if the fourth of his people had behaved as well, the day would have been his own. Round him his knights too fought with great courage. Many were slain at his side, and others were obliged to yield themselves prisoners. The King himself was twice wounded in the face, but still fought bravely on. Many of the English who knew him pressed round in eagerness to take him, crying out, "Surrender yourself, or you are a dead man." He was getting very roughly treated, when a young knight, called Denys Morbeque, forced his way through the medley, and bade the King surrender to him. Then the King turned to him, and said, "To whom shall I surrender myself? Where is my cousin, the Prince of Wales? If I could see him I would speak to him." "Sire," answered Denys, "he is not here; but surrender yourself to me, and I will lead you to him." Then the King asked who he was; and on learning, gave him his right hand glove, and said, "I surrender myself to you."
