So Sir Launcelot and all those lords who were condemned with him departed from the coast of England and entered into France, where they took up their lodging with much sorrow and repining.

And King Arthur seized upon all their earldoms, baronies, and estates, and some of these he bestowed elsewhere and some of them he held for the crown.

Now after those knights had departed for France, Sir Gawaine urged upon King Arthur that he should follow them to that kingdom and attack them there at the Castle of Chillion. King Arthur said, “Sir, why should I do this thing? Did not Sir Launcelot bring back my Queen to me and did I not forgive him for what he had done? Is he not now banished from the land, and is he not then punished for all those things that he has done? Let him now live and die in peace.”

But to this Sir Gawaine ever answered, “Sir, I cannot reconcile it to myself thus to surrender my rights in this case. For Sir Launcelot slew my brothers and my sons, and never will I forgive him for that offence. Either his blood or my blood shall answer for this; wherefore, if thou wilt not follow him to France, then I myself will go thither and will seek him out and punish him. As for thee, thou mayst forgive him as a man, but yet thou mayst not forgive him as a king. For as a king thou art the head of the law, wherefore thou mayst not forgive one who hath broken the law. So with Sir Launcelot of the Lake, for he broke the laws and he brought these Knights of the Round Table against thee and to follow him; wherefore it is thy duty under the law to assail him and to punish him for his treason, and also to punish those who follow him likewise for their treason.”

The King moveth against Sir Launcelot.

Now by this time King Arthur was growing toward being an old man, and he was much broken by sorrow and by cares, wherefore these words of Sir Gawaine so moved him that at last he agreed to sail with an army into France and to attack Sir Launcelot and his friends at Chillion. So King Arthur entrusted the government of Britain to his nephew, Sir Mordred (who was brother to Sir Gawaine), and he and Sir Gawaine departed with a great army for France.

So this army appeared before the Castle of Chillion, and they shut Sir Launcelot and his friends up within the castle and besieged them at that place.

Then said Sir Launcelot, “How is this; hath not King Arthur any mercy upon us, or doth he seek our lives and our blood? Well, if he seeks those lives and that blood, then will there be many cruel and bitter battles betwixt us, and many knights shall fall, and so will come the entire end of the Round Table. Ah, well, if God willeth that it be so, so it must be.”

Of the battles about Chillion.

So there were many battles around about Chillion and many lost their lives. And though the knights of King Arthur lost more lives than did the knights of Sir Launcelot, yet they could better afford to lose those lives because new knights were constantly coming from Britain to replenish the army of King Arthur, but no new knights were coming to the army of Sir Launcelot, wherefore his losses were not replenished to him.
