Then Lynette laughed so high and so shrill that Beaumains heard her even in the midst of his swoon, and with that his spirit came back to him again and straightway he leaped up to his feet and drew his sword. And he cried out to the White Knight: "Sir Knight, come down from off thy horse and do battle with me afoot, for never will I be satisfied with this mischance that I have suffered."
Then the White Knight said: "Messire, how is this? I have no such cause of battle with you as that." But all the more Beaumains cried out with great vehemence, "Descend, Sir Knight, descend and fight me afoot."
"Well," quoth the White Knight, "since you will have it so, so it shall be."
Beaumains doeth battle with the White Knight.
Thereupon he voided his horse and drew his sword and straightway setting his shield before him, he came forward to the assault of Beaumains. Then immediately they met together, each lashing very fiercely at the other, and so that battle began. And so it continued, each foining and tracing this way and that like two wild bulls at battle, but ever lashing stroke upon stroke at one another. Soon the armor of each was stained in places with red, for each had suffered some wound or hurt at this place or at that. Yet ever Beaumains fought with might and main, for he was so strengthened by his passion of rage that rather would he have died than yield in that battle.
So they fought with astounding fierceness for a considerable while, and then, at last, the White Knight called out, "Sir, I pray you stay this battle for a little," and with that Beaumains ceased his lashing and stood leaning upon his sword, panting for breath.
And the White Champion also leaned upon his sword and panted, and anon he said, "Sir, I pray you tell me your name. For I make my vow to you that never have I met any knight who hath fought a greater battle than you have fought this day—and yet I may tell you that I have fought with a great many of the very best knights of this realm."
"Messire," quoth Beaumains, "I may not declare my name at this present, for there are several good reasons why I will not do so. But though I may not do as you demand of me, nevertheless I beseech you that you will extend that favor unto me and will declare to me your name and your degree."
"Well," said the White Knight, "never yet have I refused that courtesy to any one who hath asked it of me. Wit ye then that I am called Sir Launcelot of the Lake."
Beaumains knoweth Sir Launcelot.
