“Fair maiden,” said Sir Lancelot, “tell me thy father’s name and I will answer thee.”

“My father is King Bagdemagus,” said she.

“I know him well,” replied Sir Lancelot, “for a noble king and a good knight; and by the faith of my body I will do him all the service I am able on that day.”

“Grammercy to thee, Sir knight,” said the damsel.

“To-morrow, when thou art delivered from this place, ride ten miles hence unto an abbey of white monks, and there abide until I bring my father to thee.”

“So be it,” said Sir Lancelot, “as I am a true knight.”

So she departed, and on the morrow, early, came again, and let him out of twelve gates, differently locked, and brought him to his armour; and when he was all armed, she brought him his horse also, and lightly he saddled him, and took a great spear in his hand, and mounted and rode forth, saying, as he went, “Fair damsel, I shall not fail thee, by the grace of God.”

And all that day he rode in a great forest, and could find no highway, and spent the night in the wood; but the next morning found his road, and came to the abbey of white monks.  And there he saw King Bagdemagus and his daughter waiting for him.  So when they were together in a chamber, Sir Lancelot told the king how he had been betrayed by an enchantment, and how his brother Lionel was gone he knew not where, and how the damsel had delivered him from the castle of Queen Morgan le Fay.  “Wherefore while I live,” said he, “I shall do service to herself and all her kindred.”

“Then am I sure of thy aid,” said the king, “on Tuesday now next coming?”

“Yea, sir, I shall not fail thee,” said Sir Lancelot; “but what knights were they who last week defeated thee, and took part with the King of Northgales?”

“Sir Mador de la Port, Sir Modred, and Sir Gahalatine,” replied the king.

“Sir,” said Sir Lancelot, “as I understand, the tournament shall take place but three miles from this abbey; send then to me here, three knights of thine, the best thou hast, and let them all have plain white shields, such as I also will; then will we four come suddenly into the midst between both parties, and fall upon thy enemies, and grieve them all we can, and none will know us who we are.”

So, on the Tuesday, Sir Lancelot and the three knights lodged themselves in a small grove hard by the lists.  Then came into the field the King of Northgales, with one hundred and sixty helms, and the three knights of King Arthur’s court, who stood apart by themselves.  And when King Bagdemagus had arrived, with eighty helms, both companies set all their spears in rest and came together with a mighty clash, wherein were slain twelve knights of King Bagdemagus, and six of the King of Northgales; and the party of King Bagdemagus was driven back.
