And so on the morn he went to mass, and there he saw the thirty ladies kneel, and lay grovelling upon divers tombs, making great dole and sorrow. Then Sir Gareth wist well that in the tombs lay their lords. Fair ladies, said Sir Gareth, ye must at the next feast of Pentecost be at the court of King Arthur, and say that I, Sir Gareth, sent you thither. We shall do this, said the ladies. So he departed, and by fortune he came to a mountain, and there he found a goodly knight that bade him, Abide sir knight, and joust with me. What are ye? said Sir Gareth. My name is, said he, the Duke de la Rowse. Ah sir, ye are the same knight that I lodged once in your castle; and there I made promise unto your lady that I should yield me unto you. Ah, said the duke, art thou that proud knight that profferest to fight with my knights; therefore make thee ready, for I will have ado with you. So they let their horses run, and there Sir Gareth smote the duke down from his horse. But the duke lightly avoided his horse, and dressed his shield and drew his sword, and bade Sir Gareth alight and fight with him. So he did alight, and they did great battle together more than an hour, and either hurt other full sore. At the last Sir Gareth gat the duke to the earth, and would have slain him, and then he yield him to him.
