So Sir Launcelot escaped, but the queen remained in the king's power, and Arthur could no longer doubt of her guilt. And the law was such in those days that they who committed such crimes, of what estate or condition soever they were, must be burned to death, and so it was ordained for Queen Guenever. Then said King Arthur to Sir Gawain, "I pray you make you ready, in your best armor, with your brethren, Sir Gaheris and Sir Gareth, to bring my queen to the fire, there to receive her death." "Nay, my most noble lord," said Sir Gawain, "that will I never do; for know thou well, my heart will never serve me to see her die, and it shall never be said that I was of your counsel in her death." Then the king commanded Sir Gaheris and Sir Gareth to be there, and they said, "We will be there, as ye command us, sire, but in peaceable wise, and bear no armor upon us."

So the queen was led forth, and her ghostly father was brought to her to shrive her, and there was weeping and wailing of many lords and ladies. And one went and told Sir Launcelot that the queen was led forth to her death. Then Sir Launcelot and the knights that were with him fell upon the troop that guarded the queen, and dispersed them, and slew all who withstood them. And in the confusion Sir Gareth and Sir Gaheris were slain, for they were unarmed and defenceless. And Sir Launcelot carried away the queen to his castle of La Joyeuse Garde.

Then there came one to Sir Gawain and told him how that Sir Launcelot had slain the knights and carried away the queen. "O Lord, defend my brethren!" said Sir Gawain. "Truly," said the man, "Sir Gareth and Sir Gaheris are slain." "Alas!" said Sir Gawain, "now is my joy gone." And then he fell down and swooned, and long he lay there as he had been dead.

When he arose out of his swoon Sir Gawain ran to the king, crying, "O King Arthur, mine uncle, my brothers are slain." Then the king wept and he both. "My king, my lord, and mine uncle," said Sir Gawain, "bear witness now that I make you a promise that I shall hold by my knighthood, and from this day I will never fail Sir Launcelot until the one of us have slain the other. I will seek Sir Launcelot throughout seven kings' realms, but I shall slay him or he shall slay me." "Ye shall not need to seek him," said the king, "for as I hear, Sir Launcelot will abide me and you in the Joyeuse Garde; and much people draweth unto him, as I hear say." "That may I believe," said Sir Gawain; "but, my lord, summon your friends, and I will summon mine." "It shall be done," said the king. So then the king sent letters and writs throughout all England, both in the length and breadth, to summon all his knights. And unto Arthur drew many knights, dukes, and earls, so that he had a great host. Thereof heard Sir Launcelot, and collected all whom he could; and many good knights held with him, both for his sake and for the queen's sake. But King Arthur's host was too great for Sir Launcelot to abide him in the field; and he was full loath to do battle against the king. So Sir Launcelot drew him to his strong castle, with all manner of provisions. Then came King Arthur with Sir Gawain, and laid siege all about La Joyeuse Garde, both the town and the castle; but in no wise would Sir Launcelot ride out of his castle, neither suffer any of his knights to issue out, until many weeks were past.

Then it befell upon a day in harvest-time, Sir Launcelot looked over the wall, and spoke aloud to King Arthur and Sir Gawain, "My lords both, all is in vain that ye do at this siege, for here ye shall win no worship, but only dishonor; for if I list to come out, and my good knights, I shall soon make an end of this war." "Come forth," said Arthur, "if thou darest, and I promise thee I shall meet thee in the midst of the field." "God forbid me," said Sir Launcelot, "that I should encounter with the most noble king that made me knight." "Fie upon thy fair language," said the king, "for know thou well I am thy mortal foe, and ever will be to my dying day." And Sir Gawain said, "What cause hadst thou to slay my brother, Sir Gaheris, who bore no arms against thee, and Sir Gareth, whom thou madest knight, and who loved thee more than all my kin? Therefore know thou well I shall make war to thee all the while that I may live."

When Sir Bohort, and Sir Hector de Marys, and Sir Lionel heard this outcry, they called to them Sir Palamedes, and Sir Saffire his brother, and Sir Lawayn, with many more, and all went to Sir Launcelot. And they said, "My lord, Sir Launcelot, we pray you, if you will have our service keep us no longer within these walls, for know well all your fair speech and forbearance will not avail you." "Alas!" said Sir Launcelot, "to ride forth and to do battle I am full loath." Then he spake again unto the king and Sir Gawain, and willed them to keep out of the battle; but they despised his words. So then Sir Launcelot's fellowship came out of the castle in full good array. And always Sir Launcelot charged all his knights, in any wise, to save King Arthur and Sir Gawain.

Then came forth Sir Gawain from the king's host and offered combat, and Sir Lionel encountered with him, and there Sir Gawain smote Sir Lionel through the body, that he fell to the earth as if dead. Then there began a great conflict, and much people were slain; but ever Sir Launcelot did what he might to save the people on King Arthur's party, and ever King Arthur followed Sir Launcelot to slay him; but Sir Launcelot suffered him, and would not strike again. Then Sir Bohort encountered with King Arthur, and smote him down; and he alighted and drew his sword, and said to Sir Launcelot, "Shall I make an end of this war?" for he meant to have slain King Arthur. "Not so," said Sir Launcelot, "touch him no more, for I will never see that most noble king that made me knight either slain or shamed;" and therewith Sir Launcelot alighted off his horse, and took up the king, and horsed him again, and said thus: "My lord Arthur, for God's love, cease this strife." And King Arthur looked upon Sir Launcelot, and the tears burst from his eyes, thinking on the great courtesy that was in Sir Launcelot more than in any other man; and therewith the king rode his way. Then anon both parties withdrew to repose them, and buried the dead.

But the war continued, and it was noised abroad through all Christendom, and at last it was told afore the pope; and he, considering the great goodness of King Arthur, and of Sir Launcelot, called unto him a noble clerk, which was the Bishop of Rochester, who was then in his dominions, and sent him to King Arthur, charging him that he take his queen, dame Guenever, unto him again, and make peace with Sir Launcelot.

So, by means of this bishop, peace was made for the space of one year; and King Arthur received back the queen, and Sir Launcelot departed from the kingdom with all his knights, and went to his own country. So they shipped at Cardiff, and sailed unto Benwick, which some men call Bayonne. And all the people of those lands came to Sir Launcelot, and received him home right joyfully. And Sir Launcelot stablished and garnished all his towns and castles, and he greatly advanced all his noble knights, Sir Lionel and Sir Bohort, and Sir Hector de Marys, Sir Blamor, Sir Lawayne, and many others, and made them lords of lands and castles; till he left himself no more than any one of them.

"Then Arthur made vast banquets, and strange knights
From the four winds came in: and each one sat,
Tho' served with choice from air, land, stream and sea,
Oft in mid-banquet measuring with his eyes
His neighbor's make and might."
