Then Sir Plenorius heard a knight call that said: Sir Plenorius, where art thou? either thou must deliver me the prisoner that thou hast led unto thy tower, or else come and do battle with me. Then Plenorius gat his horse, and came with a spear in his hand walloping toward Sir Launcelot; and then they began to feutre their spears, and came together as thunder, and smote either other so mightily that their horses fell down under them. And then they avoided their horses, and pulled out their swords, and like two bulls they lashed together with great strokes and foins; but ever Sir Launcelot recovered ground upon him, and Sir Plenorius traced to have gone about him. But Sir Launcelot would not suffer that, but bare him backer and backer, till he came nigh his tower gate. And then said Sir Launcelot: I know thee well for a good knight, but wit thou well thy life and death is in my hand, and therefore yield thee to me, and thy prisoner. The other answered no word, but struck mightily upon Sir Launcelot’s helm, that the fire sprang out of his eyes. Then Sir Launcelot doubled his strokes so thick, and smote at him so mightily, that he made him kneel upon his knees. And therewith Sir Launcelot leapt upon him, and pulled him grovelling down. Then Sir Plenorius yielded him, and his tower, and all his prisoners at his will.
