Then Sir Launcelot struck on the basin with the butt of his spear; and long he did so, but he saw no man.  And at length he was ware of a great knight that drove a horse before him, and across the horse there lay an armed knight bounden.  And as they came near, Sir Launcelot thought he should know the captive knight.  Then Sir Launcelot saw that it was Sir Gaheris, Sir Gawain’s brother, a knight of the Table Round.  “Now, fair knight,” said Sir Launcelot, “put that wounded knight off the horse, and let him rest awhile, and let us two prove our strength.  For, as it is told me, thou hast done great despite and shame unto knights of the Round Table, therefore now defend thee.”  “If thou be of the Table Round,” said Sir Turquine, “I defy thee and all thy fellowship.”  “That is overmuch said,” said Sir Launcelot.

Then they put their spears in the rests, and came together with their horses as fast as they might run.  And each smote the other in the middle of their shields, so that their horses fell under them, and the knights were both staggered; and as soon as they could clear their horses they drew out their swords and came together eagerly, and each gave the other many strong strokes, for neither shield nor harness might withstand their strokes.  So within a while both had grimly wounds, and bled grievously.  Then at the last they were breathless both, and stood leaning upon their swords.  “Now, fellow,” said Sir Turquine, “thou art the stoutest man that ever I met with, and best breathed; and so be it thou be not the knight that I hate above all other knights, the knight that slew my brother, Sir Carados, I will gladly accord with thee; and for thy love I will deliver all the prisoners that I have.”

“What knight is he that thou hatest so above others?” “Truly,” said Sir Turquine, “his name is Sir Launcelot of the Lake.”  “I am Sir Launcelot of the Lake, King Ban’s son of Benwick, and very knight of the Table Round; and now I defy thee do thy best.”  “Ah!” said Sir Turquine, “Launcelot, thou art to me the most welcome that ever was knight; for we shall never part till the one of us be dead.”  And then they hurtled together like two wild bulls, rashing and lashing with their swords and shields, so that sometimes they fell, as it were, headlong.  Thus they fought two hours and more, till the ground where they fought was all bepurpled with blood.

Then at the last Sir Turquine waxed sore faint, and gave somewhat aback, and bare his shield full low for weariness.  That spied Sir Launcelot, and leapt then upon him fiercely as a lion, and took him by the beaver of his helmet, and drew him down on his knees.  And he raised off his helm, and smote his neck in sunder.
