The three knights behold a very singular assault-at-arms.
Now as they sat their horses there on top of the hill they perceived of a sudden a knight clad all in red armor who came forth from a glade of trees. And they saw that the knight paraded the meadow that lay in front of the castle, and they saw that he gave challenge to those within the castle. Then they perceived that the drawbridge of the castle was let fall of a sudden and that there issued from thence ten knights clad in complete armor. And they beheld those ten knights assail the one knight in red armor, and they beheld the one knight assail the ten. And they beheld that for a while those ten withstood the one, but that he assailed them so terribly that he smote down four of them very quickly. Then they beheld that the rest brake and fled from before that one, and that the Red Knight pursued the others about the meadow with great fury. And they saw that he smote down one from out his saddle and another and another until but two of those knights were left.
Then Sir Gawaine said, “That is certainly a very wonderful sight for to see.” But the Lady of the Lake only smiled and said, “Wait a little.”
So they waited and they saw that when the Red Knight had smitten down all of his enemies but those two, and that when he had put those two in great peril of their lives, he of a sudden sheathed his sword and surrendered himself unto them. And they saw that those two knights brought the Red Knight to the castle, and that when they had brought him there a lady upon the wall thereof bespake that Red Knight as with great violence of language. And they beheld that those two knights took the Red Knight and bound his hands behind his back, and that they bound his feet beneath his horse’s belly, and that they drave him away from that place.
All this they beheld from the top of that hill, and the Lady of the Lake said unto Sir Gawaine, “There thou shalt find thy adventure, Sir Gawaine.” And Sir Gawaine said, “I will go,” and the Lady of the Lake said, “Do so.”
Thereupon, lo! she vanished from their sight and they were greatly amazed.
