then again sir tristram abode at king mark's court, ever rendering the fair isolt loyal and knightly service; for king mark would imperil his life for none, no matter what the need.

now among the cornish knights, there was much jealousy of sir tristram de liones, and chief of his enemies was his own cousin, sir andred. with lying words, sir andred sought to stir up king mark against his nephew, speaking evil of the queen and of sir tristram. now mark was afraid openly to accuse sir tristram, so he set sir andred to spy upon him. at last, it befell one day that sir andred saw sir tristram coming, alone and unarmed, from the queen's presence, and with twelve other knights, he fell upon him and bound him. then these felon knights bore sir tristram to a little chapel standing upon a great rock which jutted out into the sea. there they would have slain him, unarmed and bound. but sir tristram, perceiving their intent, put forth suddenly all his strength, burst his bonds, and wresting a sword from sir andred, cut him down; and so he did with six other knights. then while the rest, being but cowards, gave back a little, he shut to and bolted the doors against them, and sprang from the window on to the sea-washed rocks below. there he lay as one dead, until his squire, gouvernail, coming in a little boat, took up his master, dressed his wounds, and carried him to the coast of england.

so sir tristram was minded to remain in that country for a time. then, one day, as he rode through the forest near camelot, there came running to him a fair lady who cried: "sir tristram, i claim your aid for the truest knight in all the world, and that is none other than king arthur." "with a good heart," said sir tristram; "but where may i find him?" "follow me," said the lady, who was none other than the lady of the lake herself, and ever mindful of the welfare of king arthur. so he rode after her till he came to a castle, and in front of it he saw two knights who beset at once another knight, and when sir tristram came to the spot, the two had borne king arthur to the ground and were about to cut off his head. then sir tristram called to them to leave their traitor's work and look to themselves; with the word, one he pierced through with his spear and the other he cut down, and setting king arthur again upon his horse, he rode with him until they met with certain of arthur's knights. but when king arthur would know his name, tristram would give none, but said only that he was a poor errant knight; and so they parted.

but arthur, when he was come back to camelot, sent for sir launcelot and other of his knights, bidding them seek for such an one as was sir tristram and bring him to the court. so they departed, each his own way, and searched for many days, but in vain. then it chanced, at last, as sir launcelot rode on his way, he espied sir tristram resting beside a tomb; and, as was the custom of knights errant, he called upon him to joust. so the two ran together and each broke his spear. then they sprang to the ground and fought with their swords, and each thought that never had he encountered so stout or so skilled a knight. so fiercely they fought that, perforce, at last they must rest. then said sir launcelot: "fair knight, i pray you tell me your name, for never have i met so good a knight." "in truth," said sir tristram, "i am loth to tell my name." "i marvel at that," said sir launcelot; "for mine i will tell you freely. i am launcelot du lac." then was sir tristram filled at once with joy and with sorrow; with joy that at last he had encountered the noblest knight of the round table, with sorrow that he had done him such hurt, and without more ado he revealed his name. now sir launcelot, who ever delighted in the fame of another, had long desired to meet sir tristram de liones, and rejoicing to have found him, he knelt right courteously and proffered him his sword, as if he would yield to him. but tristram would not have it so, declaring that, rather, he should yield to sir launcelot. so they embraced right heartily, and when sir launcelot questioned him, sir tristram acknowledged that it was he who had come to king arthur's aid. together, then, they rode to camelot, and there sir tristram was received with great honour by king arthur, who made him knight of the round table.

presently, to tristram at camelot, there came word that king mark had driven the fair isolt from court, and compelled her to have her dwelling in a hut set apart for lepers. then sir tristram was wroth indeed, and mounting his horse, rode forth that same hour, and rested not till he had found the lepers' hut, whence he bore the queen to the castle known as the joyous garde; and there he held her, in safety and honour, in spite of all that king mark could do. and all men honoured sir tristram, and felt sorrow for the fair isolt; while as for king mark, they scorned him even more than before.

but to sir tristram, it was grief to be at enmity with his uncle who had made him knight, and at last he craved king arthur's aid to reconcile him to mark. so then the king, who loved sir tristram, sent messengers to cornwall to mark, bidding him come forthwith to camelot; and when the cornish king was arrived, arthur required him to set aside his enmity to tristram, who had in all things been his loyal nephew and knight. and king mark, his head full of hate, but fearful of offending his lord, king arthur, made fair proffers of friendship, begging sir tristram to return to cornwall with him, and promising to hold him in love and honour. so they were reconciled, and when king mark returned to cornwall, thither sir tristram escorted the fair isolt, and himself abode there, believing his uncle to mean truly and honourably by him.

but under a seeming fair exterior, king mark hated sir tristram more than ever, and waited only to have him at an advantage. at length he contrived the opportunity he sought. for he hid him in the queen's chamber at a time when he knew sir tristram would come there unarmed, to harp to the fair isolt the music that she loved. so as sir tristram, all unsuspecting, bent over his harp, mark leaped from his lurking place and dealt him such a blow from behind that, on the instant, he fell dead at the feet of the fair isolt. so perished the good knight, sir tristram de liones nor did the fair isolt long survive him, for refusing all comfort, she pined away, and died within a few days, and was laid in a tomb beside that of her true knight. but the felon king paid the price of his treachery with his life; for sir launcelot himself avenged the death of his friend and the wrongs of the fair isolt.
