"Be ye of good cheer," said Sir Percivale, "and because ye are a knight of the Round Table as well as I, I trust to God to make you free."

Therewith Sir Percivale drew out his sword, and struck at the chain with such a might that he cut a-two the chain, and through Sir Persides' hauberk, and hurt him a little.

"Truly," said Sir Persides, "that was a mighty stroke if ever I felt one, for had it not been for the chain, ye had slain me."

Therewithal Sir Persides saw a knight coming out of the castle, flying all that ever he might. "Beware, sir," said he; "yonder cometh a man that will have ado with you."

"Let him come," said Sir Percivale.

So he met with that knight in the midst of the bridge, and gave him such a buffet that he smote him quite from his horse and over a part of the bridge so that, had there not been a little vessel under the bridge, that knight had been drowned. Then Sir Percivale took the knight's horse, and made Sir Persides to mount upon him. So they rode to the castle, and made the lady deliver Sir Persides' servants.

Had he not had a great matter in hand, he would have remained to do away with the evil customs there. But Sir Percivale might not long abide, for he rode to seek Sir Launcelot.

Sir Persides brought him unto his own castle, and there made him great cheer for that night. Then on the morn, when Sir Percivale had heard mass and broken his fast, he said to Sir Persides: "Ride unto King Arthur, and tell the King how that ye met with me, and tell my brother Sir Aglovale how I rescued you, and bid him seek not after me, for I am in the quest to seek Sir Launcelot of the Lake, and will not see him or the court till Sir Launcelot is found. Also tell Sir Kay and Sir Mordred that I trust to God to be of as good worthiness as either of them, and that I will never see that court till men speak more honour of me than ever men did of any of them both."

So Sir Persides departed from Sir Percivale, and rode unto King Arthur, and told there of Sir Percivale. And King Arthur said he must needs prove a good knight, for his father and his brethren were noble knights.

Now turn we to Sir Launcelot, and speak we of his care and woe and what pain he endured from cold, hunger, and thirst. As he wandered like a mad man here and there, he by fortune came to the castle of King Pelles. There he was healed of his madness, and when he was recovered he was sore ashamed that he had thus been clean out of his wit. And King Pelles gave him his castle of Bliant, that stood in an island enclosed with a fair water, deep and large. Sir Launcelot called it the Joyous Isle, and here he dwelt a long while. Because he was driven from King Arthur's court he desired not to be known, and he named himself "The knight that hath trespassed."
