Percival follows Sir Boindegardus.
Now after a long time, he came to another level meadow of grass, and there he beheld Sir Boindegardus riding before him in great state with the golden goblet hanging to the horn of his saddle. And Sir Boindegardus wore his helmet and carried his spear in his right hand and his shield upon his other arm, and he was in all ways prepared for an encounter at arms. And when he perceived Percival come riding out of the forest in pursuit of him, he drew rein and turned. And when Percival had come nigh enough Sir Boindegardus said, "Whence comest thou, fool?" Percival replied, "I come from Queen Guinevere, her pavilion." Then Sir Boindegardus said, "Does that knight who was there follow me hitherward?" Unto which Percival made reply: "Nay, but I have followed thee with intent to punish thee for the affront which thou didst put upon Queen Guinevere."
Then Sir Boindegardus was very wroth and he said: "Thou fool; I have a very good intention for to slay thee." Therewith he raised his spear and smote Percival with it upon the back of the neck so terrible a blow that he was flung violently down from off his horse. Upon this Percival was so angry that the sky all became like scarlet before his eyes. Wherefore, when he had recovered from the blow he ran unto Sir Boindegardus and catched the spear in his hands and wrestled with such terrible strength that he plucked it away from Sir Boindegardus. And having thus made himself master of that spear, he brake it across his knee and flung it away.
Percival slays Sir Boindegardus.
Then Sir Boindegardus was in furious rage, wherefore he drew his bright, shining sword with intent to slay Percival. But when Percival saw what he would be at, he catched up his javelin and, running to a little distance, he turned and threw it at Sir Boindegardus with so cunning an aim that the point of the javelin entered the ocularium of the helmet of Sir Boindegardus and pierced through the eye and the brain and came out of the back of the head. Then Sir Boindegardus pitched down from off his horse all into a heap upon the ground, and Percival ran to him and stooped over him and perceived that he was dead. Then Percival said: "Well, it would seem that I have put an end to a terribly discourteous knight to ladies."
King Arthur sends Sir Launcelot and Sir Lamorack in quest of Percival.
Now a little after Percival had quitted the pavilion of Queen Guinevere, King Arthur and eleven noble knights of the court returned thither from hawking, and amongst those knights was Sir Launcelot of the Lake and Sir Lamorack of Gales. Then those who were of the Queen's court told King Arthur what had befallen, and thereat the King felt great displeasure toward Sir Kay. And he said: "Kay, not only hast thou been very discourteous in not assuming this quarrel of the Queen's, but I believe that thou, a well-approved knight, hast in thy fear of Sir Boindegardus been the cause of sending this youth upon an adventure in which he will be subject to such great danger that it may very well be that he shall hardly escape with his life. Now I will that two of you knights shall follow after that youth for to rescue him if it be not too late; and those two shall be Sir Launcelot of the Lake and Sir Lamorack of Gales. So make all haste, Messires, lest some misfortune shall befall this brave, innocent madman."
Thereupon those two knights mounted straightway upon their horses and rode away in that direction whither Percival had gone.
