Anon, by chance, he came to the same forest where the four queens had found him sleeping, and there he met a damsel riding on a white palfrey. When they had saluted each other, Sir Lancelot said, "Fair damsel, knowest thou where any adventures may be had in this country?" "Sir knight," said she, "there are adventures great enough close by if thou darest prove them." "Why should I not," said he, "since for that cause I came here?" "Sir," said the damsel, "hard by this place there dwelleth a knight that cannot be defeated by any man, so great and perilously strong he is. His name is Sir Turquine, and in the prisons of his castle lie three score knights and four, mostly from King Arthur's court, whom he hath taken with his own hands. But promise me, ere thou undertakest their deliverance, to go and help me afterwards, and free me and many other ladies that are distressed by a false knight." "Bring me but to this felon Turquine," quoth Sir Lancelot, "and I will afterwards fulfill all your wishes." So the damsel went before, and brought him to a ford, and a tree whereon a great brass basin hung; and Sir Lancelot beat with his spear-end upon the basin, long and hard, until he beat the bottom of it out, but he saw nothing. Then he rode to and fro before the castle gates for wellnigh half an hour, and anon saw a great knight riding from the distance, driving a horse before him, across which hung an armed man bound. And when they came near, Sir Lancelot knew the prisoner for a knight of the Round Table. By that time, the great knight who drove the prisoner saw Sir Lancelot, and each of them began to settle his spear, and to make ready. "Fair sir," then said Sir Lancelot, "put off that wounded knight, I pray thee, from his horse, and let him rest while thou and I shall prove our strength upon each other; for, as I am told, thou doest, and hast done, great shame and injury to knights of the Round Table. Wherefore, I warn thee now, defend thyself." "If thou mayest be of the Round Table," answered Turquine, "I defy thee, and all thy fellows." "That is saying overmuch," said Sir Lancelot. Then, setting their lances in rest, they spurred their horses towards each other, as fast as they could go, and smote so fearfully upon each other's shields, that both their horses' backs brake under them. As soon as they could clear their saddles, they took their shields before them, and drew their swords, and came together eagerly, and fought with great and grievous strokes; and soon they both had many grim and fearful wounds, and bled in streams. Thus they fought two hours and more, thrusting and smiting at each other, wherever they could hit. Anon, they both were breathless, and stood leaning on their swords. "Now, comrade," said Sir Turquine, "let us wait awhile, and answer me what I shall ask thee." "Say on," said Lancelot.
