As soon as Sir Launcelot came within the abbey yard, King Bagdemagus' daughter heard a great horse go on the pavement. And then she arose and went unto a window, and there she saw that it was Sir Launcelot, and anon she made men hastily to go to him, which took his horse and led him into a stable, and himself was led into a fair chamber, and there he unarmed him, and the lady sent to him a long gown, and anon she came herself. And then she made Sir Launcelot passing good cheer, and she said he was the knight in the world that was most welcome to her. Then she in all the haste sent for her father King Bagdemagus, that was within twelve miles of that abbey, and before even he came with a fair fellowship of knights with him. And when the king was alighted from his horse, he went straight unto Sir Launcelot's chamber, and there found his daughter, and then the king embraced Sir Launcelot in his arms, and either made other good cheer. Anon Sir Launcelot made his complaint unto the king how he was betrayed, and how his brother Sir Lionel was departed from him he wist not whither, and how his daughter had delivered him out of prison, "wherefore I shall while I live do her service and all her friends and kindred."
"Then am I sure of your help," said the king, "now on Tuesday next coming?"
"Ye, sir," said Sir Launcelot, "I shall not fail you, for so have I promised unto my lady, your daughter. As I hear say that the tournament shall be within this three mile of this abbey, ye shall send unto me three knights of yours such as ye trust, and look that the three knights have all white shields, and I also, and no painture on the shields, and we four will come out of a little wood in the midst of both parties, and we shall fall in the front of our enemies and grieve them that we may; and thus shall I not be known what knight I am." So they took their rest that night, and this was on the Sunday. And so the king departed, and sent unto Sir Launcelot three knights, with the four white shields.
And on the Tuesday they lodged them in a little leaved wood beside where the tournament should be. And there were scaffolds that lords and ladies might behold, and to give the prize. Then came into the field the King of Northgalis with eightscore helms. And then the three knights of Arthur stood by themselves. Then came into the field King Bagdemagus with fourscore of helms. And then they fewtred [placed in rest] their spears, and came together with a great dash, and there were slain of knights, at the first encounter, twelve of King Bagdemagus' party, and six of the King of Northgalis' party, and King Bagdemagus' party was far set aback.
With that came Sir Launcelot du Lake, and he thrust in with his spear in the thickest of the press, and there he smote down with one spear five knights, and of four of them he brake their backs. And in that throng he smote down the King of Northgalis, and brake his thigh in that fall. All this doing of Sir Launcelot saw the three knights of Arthur.
"Yonder is a shrewd guest," said Sir Mador de la Porte, "therefore have here once at him."
So they encountered, and Sir Launcelot bare him down horse and man, so that his shoulder went out of joint.
"Now befalleth it to me to joust," said Mordred, "for Sir Mador hath a sore fall."
