When Lancelot knew Perceval and Messire Gawain he made great joy of them and they of him.
"Lancelot," saith Messire Gawain, "This knight that led us hither to save your life is cousin to the Poor Knight of the Waste Castle, the brother of the two poor damsels that lodged us so well. We will send him these horses, one for the knight that shall be the messenger, and the two to the lord of the Waste Castle, and this hold that we have taken shall be for the two damsels, and so shall we make them safe all the days of their life. This, methinketh, will be well."
"Certes," saith Perceval, "you speak of great courtesy."
"Sir," saith Lancelot, "Messire Gawain hath said, and right willingly will I grant him all his wish."
"Lords," saith the knight, "They have in this forest a hold wherein the knights did bestow their plunder, for the sake whereof they murdered the passers by. If the goods remain there they will be lost, for therein is so great store as might be of much worth to many folk that are poverty-stricken for want thereof."
They go to the hold and find right great treasure in a cave underground, and rich sets of vessels and rich ornaments of cloth and armours for horses, that they had thrown the one over another into a pit that was right broad.
"Certes," saith he, "Right well hath it been done to this evil folk that is destroyed!"
"Sir," saith Lancelot, "in like manner would they have dealt with me and killed me if they might; whereof no sorrow have I save of the damsel that I slew, that was one of the fairest dames of the world. But I slew her not knowingly, for I meant rather to strike the knight, but she leapt between us, like the hardiest dame that saw I ever."
"Sirs," saith the knight, "Perceval and Lancelot, by the counsel of Messire Gawain, granted the treasure to the two damsels, sisters to the Poor Knight of the Waste Castle, whereupon let them send for Joseus the Hermit and bid him guard the treasure until they shall come hither."
And Joseus said that he would do so, and is right glad that the robbers of the forest are made away withal, that had so often made assault upon him. He guarded the treasure and the hold right safely in the forest; but the dread and the renown of the good knights that had freed the forest went far and wide. The knight that led the three destriers was right joyfully received at the Waste Castle; and when he told the message wherewith he was charged by Messire Gawain, the Poor Knight and two damsels made great joy thereof. Perceval taketh leave of Messire Gawain and Lancelot, and saith that never will he rest again until he shall have found his sister and his widow mother. They durst not gainsay him, for they know well that he is right, and he prayeth them right sweetly that they salute the King and Queen and all the good knights of the court, for, please God, he will go see them at an early day. But first he was fain to fulfil the promise King Arthur made to his sister, for he would not that the King should be blamed in any place as concerning him, nor by his default; and he himself would have the greater blame therein and he succoured her not, for the matter touched him nearer than it did King Arthur.
