How Sir Tristram was discovered with the Lady Belle Isoult; how he assaulted King Mark, and how he escaped from Tintagel into the forest.  
After Sir Tristram had thus rescued the Lady Belle Isoult from the hand of Sir Palamydes, he dwelt very peacefully at the court of Cornwall for all of that winter and until the spring that followed, and during that time he was given every meed of praise and honor. But although King Mark and his court gave praise to Sir Tristram with the lips, yet he and many of his people hated Sir Tristram at heart, and there were many mischief-makers about the court who were ever ready to blow the embers of the King's wrath into a flame.
 
Now the chiefest of all these mischief-makers was Sir Andred, who was nephew unto King Mark, and cousin-germaine unto Sir Tristram. Sir Andred was a fierce strong knight, and one very dextrous at arms; but he was as mean and as treacherous as Sir Tristram was generous and noble, wherefore he hated Sir Tristram with great bitterness (though he dissembled that hatred) and sought for every opportunity to do Sir Tristram a harm by bringing him and the King into conflict.
Sir Andred of Cornwall sets spies upon Sir Tristram.
 
So Sir Andred set spies upon Sir Tristram, and he himself spied upon his cousin, yet neither he nor they were able to find anything with which to accuse Sir Tristram. Then one day Sir Andred came to Sir Tristram and said: "Sir, the Lady Belle Isoult wishes to see you to talk with you." Sir Tristram said, "Where is she?"
 
And Sir Andred said, "She is in her bower." Then Sir Tristram said, "Very well, I will go to her."
 
So Sir Tristram arose and departed from where he was with intent to find the lady; and therewith Sir Andred hurried to where King Mark was, and said: "Lord, arise, for Sir Tristram and the Lady Isoult are holding converse together."
 
King Mark said, "Where are they?" And Sir Andred said, "They are in the bower of the Queen." At that King Mark's rage and jealousy blazed up into a flame, so that he was like one seized with a sudden frensy. So, in that madness of rage, he looked about for some weapon with which to destroy Sir Tristram, and he perceived a great sword where it hung against the wall. Thereupon he ran to the sword and took it down from where it was, and ran with all speed to that place where Sir Tristram and the Lady Isoult were, and Sir Andred guided him thither.
King Mark assaults Sir Tristram.
 
And when King Mark reached the bower of the Lady Isoult he flung open the door and found Sir Tristram and the Lady Isoult sitting together in the seat of a deep window. And he perceived that the Lady Isoult wept and that Sir Tristram's face was very sorrowful because of her sorrow. Then King Mark twisted him about and bent double as with a great pain, and then he cried out thrice in a voice very hoarse and loud: "Traitor! Traitor! Traitor!" Saying those words three times. Therewith he ran at Sir Tristram and struck furiously at him with that sword he held, with intent to slay him.
 
Now Sir Tristram was at that time altogether without armor and was clad in clothes of scarlet silk. Accordingly, he was able to be very quick and alert in his movements. So perceiving King Mark rushing upon him with intent to slay him he leaped aside and so avoided the blow. Then immediately he rushed in upon King Mark and catched him by the wrist and wrenched the sword out of his hand.
 
Then Sir Tristram was blinded with his rage and might have slain his uncle, but the Lady Isoult, beholding the fury in his face, shrieked in a very piercing voice, "Forbear! Forbear!" And therewith he remembered him how that King Mark was his mother's brother and that it was his hand that had made him a knight.
Sir Tristram beats King Mark.
Sir Tristram assaults King Mark
 
So he turned the sword in his hand and he smote King Mark with the flat thereof again and again, and at those blows King Mark was filled with terror so that he howled like a wild beast. And King Mark fled away from that place, striving to escape, but Sir Tristram ever pursued him, grinding his teeth like a wild boar in rage, and smiting the King as he ran, over and over again, with the flat of the sword so that the whole castle was filled with the tumult and uproar of that assault.
 
Then many of the knights of Cornwall came running with intent to defend the King, and with them came Sir Andred. But when Sir Tristram saw them, his rage suddenly left the King and went out toward them; so therewith, naked of armor as he was, he rushed at them, and he struck at them so fiercely that they were filled with the terror of his fury, and fled away from before his face. And Sir Tristram chased them through the courts of the castle, striking right and left until he was weary with striking, and many he struck down with the fierceness of his blows, and amongst them was Sir Andred who was sorely wounded. So after a while Sir Tristram grew weary of that battle, and he cried out, "Certes, these are not knights, but swine!" And therewith he ceased striking, and allowed those who could do so to escape.
Sir Tristram departs from Tintagel.
 
Thereafter he went to his chamber and armed himself without summoning Gouvernail, and after that he took horse and rode away altogether from that place. And not even Gouvernail went with him, but only his favorite hound, hight Houdaine, which same followed him into the forest as he rode thitherward. And in his going Sir Tristram looked neither to the right nor to the left but straight before him very proudly and haughtily, and no one dared to stay him in his going.
 
Yet, though he appeared so steadfast, he was like one who was brokenhearted, for he wist that in going away from that place he was leaving behind him all that he held dear in the world, wherefore he was like one who rode forth from a pleasant garden into an empty wilderness of sorrow and repining.
Gouvernail finds Sir Tristram in the forest.
 
Then, some little while after Sir Tristram had gone, Gouvernail also took horse and rode into the forest, and he searched for a long while in the forest without finding his master. But after a while he came upon Sir Tristram seated under a tree with his head hanging down upon his breast. And Houdaine lay beside Sir Tristram and licked his hand, but Sir Tristram paid no heed to him, being so deeply sunk in his sorrow that he was unaware that Houdaine licked his hand in that wise.
 
Then Gouvernail dismounted from his horse and came to where Sir Tristram was, and Gouvernail wept at beholding the sorrow of Sir Tristram. And Gouvernail said: "Messire, look up and take cheer, for there must yet be joy for thee in the world."
 
Then Sir Tristram raised his eyes very slowly (for they were heavy and dull like lead) and he looked at Gouvernail for some while as though not seeing him. Then by and by he said: "Gouvernail, what evil have I done that I should have so heavy a curse laid upon me?" Gouvernail said, still weeping: "Lord, thou hast done no ill, but art in all wise a very noble, honorable gentleman." "Alas!" quoth Sir Tristram, "I must unwittingly have done some great evil in God's sight, for certes the hand of God lieth grievously heavy upon me." Gouvernail said: "Lord, take heart, and tell me whither shall we go now?" And Sir Tristram said, "I know not."
 
Then Gouvernail said: "Lord, let us go hence, I care not where, for I reckon nothing of storm or rain or snow or hail if it so be that I am with you."
Sir Tristram bids Gouvernail return to Tintagel.
 
Then Sir Tristram looked upon Gouvernail and smiled, and he said: "Gouvernail, it is great joy to me that you should love me so greatly as you do. But this time you may not go with me whither I go, for the Lady Belle Isoult hath few friends at the court of Cornwall, and many enemies, wherefore I would have you return unto her for my sake, so that you may befriend her and cherish her when that I am no longer by her for to stand her friend in her hour of need. And take this dog Houdaine with you and bid the Lady Belle Isoult for to keep him by her to remind her of my faithfulness unto her. For even as this creature is faithful unto me under all circumstances, so am I faithful unto her whether she be glad or sorry, or in good or evil case. So return to Tintagel as I bid thee, and see that thou pay thy duty unto that lady even as thou payst it unto me. For she is so singularly dear unto me that, even as a man's heart is the life of his body, so is her happiness the life of my life."
 
Then Gouvernail wept again in very great measure, and he said, "Lord, I obey." Therewith he mounted his horse, still weeping with a great passion of sorrow, and rode away from that place, and Houdaine followed after him and Sir Tristram was left sitting alone in the deep forest.
Sir Tristram wanders in the forest mad.
 
After that Sir Tristram wandered for several days in the forest, he knew not whither for he was bewildered with that which had happened; so that he ate no food and took no rest of any sort for all that time. Wherefore, because of the hardship he then endured, he by and by became distraught in his mind. So, after a while, he forgot who he himself was, and what was his condition, or whence he came or whither he wended. And because his armor weighed heavily upon him, he took it off and cast it away from him, and thereafter roamed half naked through the woodlands.
 
Now upon the sixth day of this wandering he came to the outskirts of the forest and nigh to the coast of the sea at a spot that was not very far away was the castle of the Lady Loise, where............
