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.

Vivien cometh to the field 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.”

King Arthur is sorely wounded by Excalibur.

So these two knights came together in battle afoot, and first they foined 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.
