SO Sir Tristram departed, and took the sea, and with good wind he arrived up at Tintagil in Cornwall; and when King Mark was whole in his prosperity there came tidings that Sir Tristram was arrived, and whole of his wounds: thereof was King Mark passing glad, and so were all the barons; and when he saw his time he rode unto his father, King Meliodas, and there he had all the cheer that the king and the queen could make him. And then largely King Meliodas and his queen departed of their lands and goods to Sir Tristram.

Then by the license of King Meliodas, his father, he returned again unto the court of King Mark, and there he lived in great joy long time, until at the last there befell a jealousy and an unkindness betwixt King Mark and Sir Tristram, for they loved both one lady. And she was an earl's wife that hight Sir Segwarides. And this lady loved Sir Tristram passingly well. And he loved her again, for she was a passing fair lady, and that espied Sir Tristram well. Then King Mark understood that and was jealous, for King Mark loved her passingly well.

So it fell upon a day this lady sent a dwarf unto Sir Tristram, and bade him, as he loved her, that he would be with her the night next following. Also she charged you that ye come not to her but if ye be well armed, for her lover was called a good knight. Sir Tristram answered to the dwarf: Recommend me unto my lady, and tell her I will not fail but I will be with her the term that she hath set me. And with this answer the dwarf departed. And King Mark espied that the dwarf was with Sir Tristram upon message from Segwarides' wife; then King Mark sent for the dwarf, and when he was come he made the dwarf by force to tell him all, why and wherefore that he came on message from Sir Tristram. Now, said King Mark, go where thou wilt, and upon pain of death that thou say no word that thou spakest with me; so the dwarf departed from the king.

And that same night that the steven was set betwixt Segwarides' wife and Sir Tristram, King Mark armed him, and made him ready, and took two knights of his counsel with him; and so he rode afore for to abide by the way for to wait upon Sir Tristram. And as Sir Tristram came riding upon his way with his spear in his hand, King Mark came hurtling upon him with his two knights suddenly. And all three smote him with their spears, and King Mark hurt Sir Tristram on the breast right sore. And then Sir Tristram feutred his spear, and smote his uncle, King Mark, so sore, that he rashed him to the earth, and bruised him that he lay still in a swoon, and long it was or ever he might wield himself. And then he ran to the one knight, and eft to the other, and smote them to the cold earth, that they lay still. And therewithal Sir Tristram rode forth sore wounded to the lady, and found her abiding him at a postern.
