Now after Sir Accalon and the Lady of the Pavilion had broken their fasts she spake to him in this wise, "Sir knight, thou appearest to be a very strong and worthy lord and one very well used to feats of arms and to prowess in battle."
To this Sir Accalon made reply, "Lady, it does not beseem me to bespeak of my own worth, but this much I may freely say; I have engaged in several affrays at arms in such measure as a knight with belt and spurs may do, and I believe that both my friends and mine enemies have had reason to say that I have at all times done my devoirs to the best of my powers."
Then the damoiselle said, "I believe you are a very brave and worthy knight, and being such you might be of service to a good worthy knight who is in sad need of such service as one knight may render unto another." To this Sir Accalon said, "What is that service?" And the damoiselle replied, "I will tell thee: There is, dwelling not far from this place, a certain knight hight Sir Ontzlake, who hath an elder brother hight Sir Domas. This Sir Domas hath served Sir Ontzlake very ill in many ways, and hath deprived him of well nigh all of his patrimony, so that only a little is left to Sir Ontzlake of all the great possessions that were one time his father's. But even such a small holding as that Sir Domas begrudges Sir Ontzlake, so that Sir Ontzlake must needs hold what he hath by such force of arms as he may himself maintain. Now Sir Domas hath found himself a champion who is a man of a great deal of strength and prowess, and through this champion Sir Domas challenges Sir Ontzlake's right to hold even that small part of those lands which were one time his father's; wherefore if Sir Ontzlake would retain what is his he must presently do battle therefore.
"Now this is a very sad case for Sir Ontzlake, for a short time since he was wounded by a spear at a tournament and was pierced through both of his thighs, wherefore he is not now able to sit upon his horse and to defend his rights against assault. Wherefore meseems that a knight could have no better cause to show his prowess than in the defence of so sad a case as this."
So spake that lady, and to all she said Sir Accalon listened with great attention, and when she had ended he said, "Lady, I would be indeed right willing to defend Sir Ontzlake's right, but, lo! I have no armor nor have I any arms to do battle withal."
Then that damoiselle smiled very kindly upon Sir Accalon and she said to him, "Sir, Sir Ontzlake may easily fit thee with armor that shall be altogether to thy liking. And as for arms, I have in this pavilion a sword that hath but one other fellow in all the world."
Upon this she arose and went back into that curtained recess from which she had come, and thence she presently returned, bringing a certain thing wrapped in a scarlet cloth. And she opened the cloth before Sir Accalon's eyes, and lo! that which she had there was King Arthur's sword Excalibur in his sheath. Then the damoiselle said, "This sword shall be thine if thou wilt assume this quarrel upon behalf of Sir Ontzlake."
Now when Sir Accalon beheld that sword he wist not what to think, and he said to himself, "Certes, either this is Excalibur or else it is his twin brother." Therewith he drew the blade from out of its shield and it shined with extraordinary splendor. Then Sir Accalon said, "I know not what to think for pure wonder, for this sword is indeed the very image of another sword I wot of."
When he so spake that damoiselle smiled upon him again, and she said, "I have heard tell that there is in the world another sword like to this."
Then Sir Accalon said, "Lady, to win this sword for myself I would be willing to fight in any battle whatsoever." And the damoiselle replied, "Then if thou wilt fight this battle for Sir Ontzlake thou art free to keep that sword for thine own," at the which Sir Accalon was rejoiced beyond all measure of gladness.
So it came about that, by the wiles of Queen Morgana le Fay, King Arthur was brought to fight a battle unknowingly with a knight very much beloved by him, and that that knight had Excalibur to use against his master. For all these things had come to pass through the cunning of Morgana le Fay.
Now a fair field was prepared for that battle in such a place as was convenient both to Sir Domas and to Sir Ontzlake, and thither they came upon the day assigned, each with his knight-champion and his attendants, Sir Ontzlake being brought thither in a litter because of the sore wound in his thighs. Also a great many other folk came to behold the combat, for the news thereof had gone forth to a great distance around about that place. So, all being in readiness, the two knights that were to do battle in that field were brought within the barriers of combat, each fully armed and each mounted upon a very good horse.
Now King Arthur was clad all in armor of Sir Domas, and Sir Accalon was clad in armor that belonged to Sir Ontzlake, and the head of each was covered by his helmet so that neither of those two knew the other.
Then the herald came forth and announced that the battle was toward, and each knight immediately put himself in readiness for the assault. Thereupon, the word for assault being given, the two rushed forth, each from his station, with such speed and fury that it was wonderful to behold. And so they met in the midst of the course with a roar as of thunder, and the spear of each knight was burst all into small pieces unto the truncheon which he held in his hand. Upon this each knight voided his horse with great skill and address, and allowed it to run at will in that field. And each threw aside the truncheon of his spear and drew his sword, and thereupon came, the one against the other, with the utmost fury of battle.
It was at this time that Vivien came to that place upon the behest of Merlin, and she brought with her such a Court and state of beauty that a great many people took notice of her with great pleasure.
So Vivien and her Court took stand at the barriers whence they might behold all that was toward. And Vivien regarded those two knights and she could not tell which was King Arthur and which was his enemy, wherefore she said, "Well, I will do as Merlin desired me to do, but I must wait and see this battle for a while ere I shall be able to tell which is King Arthur, for it would be a pity to cast my spells upon the wrong knight."
So these two knights came together in battle afoot, and first they joined and then they both struck at the same time and, lo! the sword of King Arthur did not bite into the armor of Sir Accalon, but the sword of Sir Accalon bit very deeply into the armor of King Arthur and wounded him so sorely that the blood ran down in great quantities into his armor. And after that they struck very often and very powerfully, and as it was at first so it was afterward, for the sword of Sir Accalon ever bit into the armor of King Arthur, and the sword of King Arthur bit not at all into his enemy's armor. So in a little while it came that King Arthur's armor was stained all over red with the blood that flowed out from a great many wounds, and Sir Accalon bled not at all because of the sheath of Excalibur which he wore at his side. And the blood of King Arthur flowed down upon the ground so that all the grass around about was ensanguined with it. So when King Arthur beheld how all the ground was wet with his own blood, and how his enemy bled not at all, he began to fear that he would die in that battle; wherefore he said to himself, "How is this? Hath the virtue departed out of Excalibur and his sheath? Were it not otherwise I would think that that sword which cutteth me so sorely is Excalibur and that this sword is not Excalibur."
Upon this a great despair of death came upon him, and he ran at Sir Accalon and smote him so sore a blow upon the helm that Sir Accalon nigh fell down upon the ground.
But at that blow the sword of King Arthur broke short off at the cross of the handle and fell into the grass among the blood, and the pommel thereof and the cross thereof was all that King Arthur held in his hand.
Now at that blow Sir Accalon waxed very mad, so he ran at King Arthur with intent to strike him some dolorous blow. But when he saw that King Arthur was without weapon, he paused in his assault and he said, "Sir Knight, I see that thou art without weapon and that thou hast lost a great deal of blood. Wherefore I demand thee to yield thyself unto me as recreant."
Then King Arthur was again very much a-dread that his death was near to him; yet, because of his royalty, it was not possible for him to yield to any knight. So he said, "Nay, Sir Knight, I may not yield myself unto thee for I would liever die with honor than yield myself without honor. For though I lack a weapon, there are peculiar reasons why I may not lack worship. Wherefore thou mayst slay me
