Then King Mark and Sir Dinadan rode forth a four leagues English, till that they came to a bridge where hoved a knight on horseback, armed and ready to joust. Lo, said Sir Dinadan unto King Mark, yonder hoveth a knight that will joust, for there shall none pass this bridge but he must joust with that knight. It is well, said King Mark, for this jousts falleth with thee. Sir Dinadan knew the knight well that he was a noble knight, and fain he would have jousted, but he had had liefer King Mark had jousted with him, but by no mean King Mark would not joust. Then Sir Dinadan might not refuse him in no manner. And then either dressed their spears and their shields, and smote together, so that through fine force Sir Dinadan was smitten to the earth; and lightly he rose up and gat his horse, and required that knight to do battle with swords. And he answered and said: Fair knight, as at this time I may not have ado with you no more, for the custom of this passage is such. Then was Sir Dinadan passing wroth that he might not be revenged of that knight; and so he departed, and in no wise would that knight tell his name. But ever Sir Dinadan thought he should know him by his shield that it should be Sir Tor.
