So Sir Gawaine and Sir Mador de la Porte made themselves ready as Sir Launcelot had advised, and when they were in all ways prepared they withdrew to a little distance so as to have a good course to run. Then when all were ready for that encounter, each knight shouted and set spurs to his horse, and all four thundered together with such violence that the ground trembled beneath them. So they met in the middle of the course and so furious was the meeting of those four good knights that you might have heard the roar of that encounter for half a mile away or more. In that encounter both Sir Lavaine and Sir Mador broke each his spear upon his enemy and neither of them suffered a fall. But Sir Gawaine had no such fortune for his spear broke into splinters unto the very truncheon thereof, and the spear of Sir Launcelot held, so that Sir Gawaine was lifted out from his saddle and flung upon the ground with such violence that he rolled thrice or four times over and over before he ceased to fall.
Now those who looked upon that encounter were well assured that Sir Gawaine would easily overthrow his opponent into the dust, for Sir Gawaine was held to be one of the very greatest knights in all of the world. Wherefore it was that when they beheld how violently he had been flung to earth by that unknown knight against whom he had tilted, they were astonished beyond all bounds of wonderment.
But Sir Mador de la Porte, when he beheld how Sir Gawaine lay there in the dust as though dead, voided his horse and ran to the fallen knight where he lay. And he raised the umbril of Sir Gawaine's helmet, and lo! the face of Sir Gawaine was like to the face of one who was dead. And at first Sir Mador thought that he was dead, but after a while Sir Gawaine sighed and then sighed again, and thereupon Sir Mador knew that he was not dead, but in a swoon from the violence of the fall. And Sir Mador rejoiced very greatly that no more ill had come of that encounter.
Then Sir Mador turned to Sir Launcelot, and cried out: "Sir Knight Malfait, go thy way in the fiend's name. For indeed thou art well named Malfait, seeing what an evil thing it is that thou hast done to this worshipful knight. For wit you that this is none other than Sir Gawaine, the nephew of King Arthur himself, whom you have overthrown; and had you slain him, as at first I believed you had, it would have been a very ill thing for you. Moreover, you are to know that this knight was to have been the leader of all those upon King Arthur's side in the battle to-morrow-day, but now God knows if he will be able to wear armor again for many days to come. Wherefore go thy way and trouble us no more."
Quoth Sir Launcelot: "Well, Sir Knight, this quarrel was altogether of your own seeking, and not of ours. Wherefore, if ill hath befallen this worshipful knight, it is of his own devising and not of mine."
But Sir Mador only cried out the more vehemently: "Go your way! Go your way, and leave us in peace!" And thereupon Sir Launcelot and Sir Lavaine drew their bridle reins and set heel to horse and rode away from that place, leaving Sir Mador and those others who were there to cherish Sir Gawaine and to revive him from his swoon as best they might.
Sir Bernard of Astolat followeth Sir Launcelot and Sir Lavaine.
Now there was among those knights who were with Sir Gawaine and Sir Mador a certain old and very worthy knight of Astolat, hight Sir Bernard, surnamed of Astolat. Seeing Sir Launcelot and Sir Lavaine departing in that wise, Sir Bernard hied him after them and when he had come up with them he saluted them, and said, "Messires, I pray ye tell me where it is ye lodge this night."
Sir Launcelot said: "Fair Sir, we know not where we lodge for we go to seek such lodging as we may find in Astolat."
Sir Bernard said: "You will find no lodging in Astolat this night, for all places are full. Now I pray ye that you will lodge with me, for I have a very good and comely house and I shall be greatly honored for to have you lodge with me. For I make my vow, Sir Knight Malfait, that never saw I such a buffet as that which you gave to Sir Gawaine anon. Nor do I believe that ever Sir Launcelot of the Lake himself could have done more doughtily than you did in that encounter. Wherefore, I think that you will win you great glory to-morrow-day, and that I shall have due worship if so be that ye two shall have lodged with me over this night."
