Down went the guard of knights before this fierce onset, till full twenty of them lay dead on the field. But by sad fortune, as Lancelot, in his warlike fury pressed hither and thither, cutting and slashing with the hot rage of the berserker, he by mishap struck the two unarmed knights, Gareth and Gaheris, and stretched them dead upon the field.
This was in the thick of the fray, and he knew not what he had done, for rather would he have slain himself than harmed these, his faithful friends. A few minutes sufficed to kill or disperse all the guard. Then Lancelot sprang from his horse, scattered the blazing fagots with his foot, and with a blow of his sword severed the bonds that fastened Guenever to the stake.
The unhappy lady fell, weeping, into his arms, thanking him in broken accents. With all due haste he mounted her on a horse that had been provided, and rode off with her and his following of gallant knights to Joyous Gard, strong of heart and stout of frame, and resolved to fight for her to the death, for more than ever he felt himself her chosen knight.
And when word went through the country round that Arthur and Lancelot were at odds, many a good knight rode in all haste to his castle, bent on taking his side in the coming war.
But when the news was brought to Arthur of how Lancelot had rescued the queen, and slain many of his knights, and in particular Gareth and Gaheris, his anger turned to such bitter sorrow and regret that he swooned from pure grief. And when he came to his senses again he deeply moaned, and reproached himself for the evil that had befallen.
"Alas! that I ever wore the crown!" he bewailed. "Within these two days I have lost forty knights, and, above all, the noble fellowship of Lancelot and his kindred, and all because I listened to the tongue of foul detraction. Alas! that ever this fatal thing began! Fair friends, see that none of you tell Gawaine of what has happened, for he loves Gareth so deeply that I fear, when he hears of his death, he will go out of his mind. How came Lancelot to slay these knights, who both loved him devotedly?"
"He would never have harmed them had he known them," said a knight. "It was in the midst of the hurtling and fierce struggling, when swords strike they know not where. Sad he will be when he learns what he has done."
"I am heavier for the loss of my knights than of my queen," said Arthur, sadly. "Other queens may be had, but such a fellowship of knights can never be brought together again. And this I know, that when Gawaine learns of Gareth's death, he will never rest, nor suffer me to rest, till I have destroyed Lancelot and his kindred, or they have destroyed me. Ah, Agravaine, Agravaine, Jesus forgive thy soul for thy evil will, for thou and thy brother Mordred have caused all this bitter sorrow."
While the king thus complained, a tale-bearer, unheeding his injunctions, came to Gawaine big with his story, and told him of the rescue of the queen, and the death of a knightly host.
"What else could Lancelot do?" said Gawaine. "I should have done as much myself had I stood in his place. But where are my brothers? Why hear I not of them?"
