At last Sir Launcelot desired of King Arthur assurance of liberty for the Queen, as also safe conduct for himself and his knights, that he might bring Dame Guenevere, with due honour, to the King at Carlisle; and thereto the King pledged his word.
So Launcelot set forth with the Queen, and behind them rode a hundred knights arrayed in green velvet, the housings of the horses of the same all studded with precious stones; thus they passed through the city of Carlisle, openly, in the sight of all, and there were many who rejoiced that the Queen was come again and Sir Launcelot with her, though they of Gawain's party scowled upon him.
When they were come into the great hall where Arthur sat, with Sir Gawain and other great lords about him, Sir Launcelot led Guenevere to the throne and both knelt before the King; then, rising, Sir Launcelot lifted the Queen to her feet, and thus he spoke to King Arthur, boldly and well before the whole court: "My lord, Sir Arthur, I bring you here your Queen, than whom no truer nor nobler lady ever lived; and here stand I, Sir Launcelot du Lac, ready to do battle with any that dare gainsay it"; and with these words Sir Launcelot turned and looked upon the lords and knights present in their places, but none would challenge him in that cause, not even Sir Gawain, for he had ever affirmed that Dame Guenevere was a true and honourable lady.
Then Sir Launcelot spoke again; "Now, my Lord Arthur, in my own defence it behooves me to say that never in aught have I been false to you."
"Peace," said the King to Sir Launcelot: "We give you fifteen days in which to leave this kingdom." Then Sir Launcelot sighed heavily and said: "Full well I see that nothing availeth me." Then he went to the Queen where she sat, and said: "Madam, the time is come when I must leave this fair realm that I have loved. Think well of me, I pray you, and send for me if ever there be aught in which a true knight may serve lady." Therewith he turned him about and, without greeting to any, passed through the hall, and with his faithful knights rode to the Joyous Garde, though ever thereafter, in memory of that sad day, he called it the Dolorous Garde.
In after times when the King had passed overseas to France, leaving Sir Mordred to rule Britain in his stead, there came messengers from Britain bearing letters for King Arthur; and more evil news than they brought might not well be, for they told how Sir Mordred had usurped his uncle's realm. First, he had caused it to be noised abroad that King Arthur was slain in battle with Sir Launcelot, and, since there be many ever ready to believe any idle rumour and eager for any change, it had been no hard task for Sir Mordred to call the lords to a Parliament and persuade them to make him King. But the Queen could not be brought to believe that her lord was dead, so she took refuge in the Tower of London from Sir Mordred's violence, nor was she to be induced to leave her strong refuge for aught that Mordred could promise or threaten.
Forthwith, King Arthur bade his host make ready to move, and when they had reached the coast, they embarked and made sail to reach Britain with all possible speed.
Sir Mordred, on his part, had heard of their sailing, and hasted to get together a great army. It was grievous to see how many a stout knight held by Mordred, ay, even many whom Arthur himself had raised to honour and fortune; for it is the nature of men to be fickle. Thus is was that, when Arthur drew near to Dover, he found Mordred with a mighty host, waiting to oppose his landing. Then there was a great sea-fight, those of Mordred's party going out in boats, to board King Arthur's ships and slay him and his men or ever they should come to land. Right valiantly did King Arthur bear him, as was his wont, and boldly his followers fought in his cause, so that at last they drove off their enemies and landed at Dover in spite of Mordred and his array.
Now, by this time, many that Mordred had cheated by his lying reports, had drawn unto King Arthur, to whom at heart they had ever been loyal, knowing him for a true and noble King and hating themselves for having been deceived by such a false usurper as Sir Mordred.
One night, as King Arthur slept, he thought that Sir Gawain stood before him, looking just as he did in life, and said to him: "My uncle and my King, God in his great love has suffered me to come unto you, to warn you that in no wise ye fight on the morrow; for if ye do, ye shall be slain, and with you the most part of the people on both sides. Make ye, therefore, a treaty." Immediately, the King awoke and called to him the best and wisest of his knights. Then all were agreed that, on any terms whatsoever, a treaty should be made with Sir Mordred, even as Sir Gawain had said; and, with the dawn, messengers went to the camp of the enemy, to call Sir Mordred to a conference. So it was determined that the meeting should take place in the sight of both armies, in an open space between the two camps, and that King Arthur and Mordred should each be accompanied by fourteen knights. Little enough faith had either in the other, so when they set forth to the meeting, they bade their hosts join battle if ever they saw a sword drawn.
Now as they talked, it befell that an adder, coming out of a bush hard by, stung a knight in the foot; and he, seeing the snake, drew his sword to kill it and thought no harm thereby. But on the instant that the sword flashed, the trumpets blared on both sides and the two hosts rushed to battle. Never was there fought a fight of such enmity; for brother fought with brother, and comrade with comrade, and fiercely they cut and thrust, with many a bitter word between; while King Arthur himself, his heart hot within him, rode through and through the battle, seeking the traitor Mordred. So they fought all day, till at last the evening fell. Then Arthur, looking round him, saw of his valiant knights but two left, Sir Lucan and Sir Bedivere, and these sore wounded; and there, over against him, by a great heap of the dead, stood Sir Mordred, the cause of all this ruin. Thereupon the King, his heart nigh broken with grief for the loss of his true knights, cried with a loud voice, "Traitor! now is thy doom upon thee!" and with his spear gripped in both hands, he rushed upon Sir Mordred and smote him that the weapon stood out a fathom behind. And Sir Mordred knew that he had his death wound. With all the might that he had, he thrust him up the spear to the haft and, with his sword, struck King Arthur upon the head, that the steel pierced the helmet and bit into the head; then Mordred fell back, stark and dead.
Sir Lucan and Sir Bedivere went to the King where he lay, swooning from the blow, and bore him to a little chapel on the seashore. As they laid him on the ground, Sir Lucan fell dead beside the King, and Arthur, coming to himself, found but Sir Bedivere alive beside him.
So King Arthur lay wounded to the death, grieving, not that his end was come, but for the desolation of his kingdom and the loss of his good knights. And looking upon the body of Sir Lucan, he sighed and said: "Alas! true knight, dead for my sake! If I lived, I should ever grieve for thy death, but now mine own end draws nigh." Then, turning to Sir Bedivere, who stood sorrowing beside him, he said: "Leave weeping now, for the time is short and much to do. Hereafter shalt thou weep if thou wilt. But take now my sword Excalibur, hasten to the water side, and fling it into the deep. Then, watch what happens and bring me word thereof." "My Lord," said Sir Bedivere, "your command shall be obeyed"; and, taking the sword, he departed. But as he went on his way, he looked on the sword, how wondrously it was formed and the hilt all studded with precious stones; and, as he looked, he called to mind the marvel by which it had come into the King's keeping. For on a certain day, as Arthur walked on the shore of a great lake, there had appeared above the surface of the water a hand brandishing a sword. On the instant, the King had leaped into a boat, and, rowing into the lake, had got the sword and brought it back to land. Then he had seen how, on one side the blade, was written, "Keep me," but on the other, "Throw me away," and, sore perplexed, he had shown it to Merlin, the great wizard, who said: "Keep it now. The time for casting away has not yet come." Thinking on this, it seemed to Bedivere that no good, but harm, must come of obeying the King's word; so hiding the sword under a tree, he hastened back to the little chapel. Then said the King: "What saw'st thou?" "Sir," answered Bedivere, "I saw naught but the waves, heard naught but the wind." "That is untrue," said King Arthur; "I charge thee, as thou art true knight, go again and spare not to throw away the sword."
Sir Bedivere departed a second time, and his mind was to obey his lord; but when he took the sword in his hand, he thought: "Sin it is and shameful, to throw away so glorious a sword" Then, hiding it again, he hastened back to the King. "What saw'st thou?" said Sir Arthur. "Sir, I saw the water lap on the crags." Then spoke the King in great wrath: "Traitor and unkind! Twice hast thou betrayed me! Art dazzled by the splendour of the jewels, thou that, till now, hast ever been dear and true
