So he departed and rode past a mountain where was a goodly knight waiting, who said to him, "Abide, Sir knight, and joust with me!" "How are ye named?" said Sir Gareth. "I am the Duke de la Rowse," answered he. "In good sooth," then said Sir Gareth, "not long ago I lodged within your castle, and there promised I would yield to you whenever we might meet." "Art thou that proud knight," said the duke, "who was ready to fight with me? Guard thyself therefore and make ready." So they ran together, and Sir Gareth smote the duke from his horse. Then they alighted and drew their swords, and fought full sorely for the space of an hour; and at the last Sir Gareth smote the duke to the earth and would have slain him, but he yielded. "Then must ye go," said Sir Gareth, "to my lord King Arthur at the next Feast of Pentecost and say that I, Sir Gareth, sent ye." "As ye will be it," said the duke; and gave him up his shield for pledge. And as Sir Gareth rode alone he saw an armed knight coming towards him. And putting the duke's shield before him he rode fast to tilt with him; and so they ran together as it had been thunder, and brake their spears upon each other. Then fought they fiercely with their swords and lashed together with such mighty strokes that blood ran to the ground on every side. And after they had fought together for two hours and more, it chanced the damsel Linet passed that way; and when she saw them she cried out, "Sir Gawain and Sir Gareth, leave your fighting, for ye are brethren!" At that they threw away their shields and swords, and took each other in their arms and wept a great while ere they could speak. And each gave to the other the honour of the battle, and there was many a kind word between them. Then said Sir Gawain, "O my brother, for your sake have I had great sorrow and labour! But truly I would honour you though ye were not my brother, for ye have done great worship to King Arthur and his court, and sent more knights to him than any of the Table Round, except Sir Lancelot." Then the damsel Linet staunched their wounds, and their horses being weary she rode her palfrey to King Arthur and told him of this strange adventure. When she had told her tidings, the king himself mounted his horse and bade all come with him to meet them. So a great company of lords and ladies went forth to meet the brothers. And when King Arthur saw them he would have spoken hearty words, but for gladness he could not. And both Sir Gawain and Sir Gareth fell down at their uncle's knees and did him homage, and there was passing great joy and gladness among them all.
