So Sir Mordred drew with a great host to Dover, for there he heard say that Sir Arthur would arrive, and so he thought to beat his own uncle from his lands. And the most part of all England held with Sir Mordred, the people were so new-fangle. As Sir Mordred was at Dover with his host, there came King Arthur with a great navy of ships, galleys, and carracks. And there was Sir Mordred ready awaiting upon his landage, to keep his own uncle from landing in the country that he was king over. Then there was launching of great boats and small, full of noble men of arms, and there was much slaughter of gentle knights, and many a bold baron was laid full low on both sides. But King Arthur was so courageous that there might no manner of knights prevent him from landing, and his knights fiercely followed him. So they landed in spite of Sir Mordred and all his power, and they put him aback, so that he fled and all his people. When this battle was done, King Arthur let bury his dead, and then was the noble knight Sir Gawaine found in a great boat lying more than half dead. When Sir Arthur wist that Sir Gawaine was laid so low, he went unto him and made sorrow out of measure, for this sister's son was the man in the world that he most loved. Sir Gawaine felt that he must die, for he was smitten upon the old wound that Sir Launcelot had given him afore the city of Benwick. He now knew that he was the cause of this unhappy war, for had Sir Launcelot remained with the King, it would never have been, and now King Arthur would sore miss his brave knights of the Round Table.
