... Great was the feasting on occasion of Arthur's settlement in his kingdom, and it came to pass on a day, when the feasting was ended, that there came to the palace a squire bearing on his horse a knight that had been wounded to the death.  When they inquired what had befallen him, he said, "There is a knight that hath set up his pavilion in the forest hard by and constrains all that pass to joust with him.  This man hath slain my master; give me, therefore, a knight who will take up my quarrel."  Thereupon there rose up one Giflet, a squire.  He was but young, being of an age with the King, but he had done good service in the wars.  "Let me take up this quarrel," said he.  "Nay," answered the King, "thou art over young."  Nevertheless, as Giflet was urgent with his demand, the King suffered him to go, having first made him a knight.  So Sir Giflet rode into the forest, and coming to the strange knight's pavilion, struck with his spear on the shield that hung thereby.  Then came out the knight, and after some parley, for the knight of the pavilion was loath to fight with the young man, they jousted together, and Sir Giflet was borne to the earth, well nigh wounded to death.  But the strange knight unlaced his helmet, and set him on his horse, and sent him to the court, where he was healed of his wound, not without much pains of the physicians...
