But when Sir Gawain heard thereof, he came before the king, and said, "My lord, I counsel thee be not too hasty in this matter, but stay the judgment of the queen a season, for it may well be that Sir Lancelot was in her chamber for no evil, seeing she is greatly beholden to him for so many deeds done for her sake, and peradventure she had sent to him to thank him, and did it secretly that she might avoid slander." But King Arthur answered, full of grief, "Alas! I may not help her; she is judged as any other woman." Then he required Sir Gawain and his brethren, Sir Gaheris and Sir Gareth, to be ready to bear the queen to-morrow to the place of execution. "Nay, noble lord," replied Sir Gawain, "that can I never do; for neither will my heart suffer me to see the queen die, nor shall men ever say I was of your counsel in this matter." Then said his brothers, "Ye may command us to be there, but since it is against our will, we will be without arms, that we may do no battle against her." So on the morrow was Queen Guinevere led forth to die by fire, and a mighty crowd was there, of knights and nobles, armed and unarmed. And all the lords and ladies wept sore at that piteous sight. Then was she shriven by a priest, and the men came nigh to bind her to the stake and light the fire. At that Sir Lancelot's spies rode hastily and told him and his kindred, who lay hidden in a wood hard by; and suddenly, with twenty knights, he rushed into the midst of all the throng to rescue her. But certain of King Arthur's knights rose up and fought with them, and there was a full great battle and confusion. And Sir Lancelot drave fiercely here and there among the press, and smote on every side, and at every blow struck down a knight, so that many were slain by him and his fellows. Then was the queen set free, and caught up on Sir Lancelot's saddle and fled away with him and all his company to the Castle of La Joyous Garde. Now so it chanced that, in the turmoil of the fighting, Sir Lancelot had unawares struck down and slain the two good knights Sir Gareth and Sir Gaheris, knowing it not, for he fought wildly, and saw not that they were unarmed. When King Arthur heard thereof, and of all that battle, and the rescue of the queen, he sorrowed heavily for those good knights, and was passing wroth with Lancelot and the queen. But when Sir Gawain heard of his brethren's death he swooned for sorrow and wrath, for he wist that Sir Lancelot had killed them in malice. And as soon as he recovered he ran in to the king, and said, "Lord king and uncle, hear this oath which now I swear, that from this day I will not fail Sir Lancelot till one of us hath slain the other. And now, unless ye haste to war with him, that we may be avenged, will I myself alone go after him."
