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. [Sidenote: _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.” [Sidenote: _King Arthur is sorely wounded by Excalibur._]
