Book X - Chapter XXXV - How it was told to King Mark of Sir Alisander, and how he would have slain Sir Sadok for saving his life.
NOW I require thee, and charge thee upon my blessing, and upon the high order of knighthood, that thou be revenged upon King Mark for the death of thy father. And therewithal she swooned. Then Alisander leapt to his mother, and took her up in his arms, and said: Fair mother, ye have given me a great charge, and here I promise you I shall be avenged upon King Mark when that I may; and that I promise to God and to you. So this feast was ended, and the Constable, by the advice of Anglides, let purvey that Alisander was well horsed and harnessed. Then he jousted with his twenty fellows that were made knights with him, but for to make a short tale, he overthrew all those twenty, that none might withstand him a buffet.
Then one of those knights departed unto King Mark, and told him all, how Alisander was made knight, and all the charge that his mother gave him, as ye have heard afore time. Alas, false treason, said King Mark, I weened that young traitor had been dead. Alas, whom may I trust? And therewithal King Mark took a sword in his hand; and sought Sir Sadok from chamber to chamber to slay him. When Sir Sadok saw King Mark come with his sword in his hand he said thus: Beware, King Mark, and come not nigh me; for wit thou well that I saved Alisander his life, of which I never repent me, for thou falsely and cowardly slew his father Boudwin, traitorly for his good deeds; wherefore I pray Almighty Jesu send Alisander might and strength to be revenged upon thee. And now beware King Mark of young Alisander, for he is made a knight. Alas, said King Mark, that ever I should hear a traitor say so afore me. And therewith four knights of King Mark's drew their swords to slay Sir Sadok, but anon Sir Sadok slew them all in King Mark's presence. And then Sir Sadok passed forth into his chamber, and took his horse and his harness, and rode on his way a good pace. For there was neither Sir Tristram, neither Sir Dinas, nor Sir Fergus, that would Sir Sadok any evil will. Then was King Mark wroth, and thought to destroy Sir Alisander and Sir Sadok that had saved him; for King Mark dreaded and hated Alisander most of any man living.
When Sir Tristram understood that Alisander was made knight, anon forthwithal he sent him a letter, praying him and charging him that he would draw him to the court of King Arthur, and that he put him in the rule and in the hands of Sir Launcelot. So this letter was sent to Alisander from his cousin, Sir Tristram. And at that time he thought to do after his commandment. Then King Mark called a knight that brought him the tidings from Alisander, and bade him abide still in that country. Sir, said that knight, so must I do, for in my own country I dare not come. No force, said King Mark, I shall give thee here double as much lands as ever thou hadst of thine own. But within short space Sir Sadok met with that false knight, and slew him. Then was King Mark wood wroth out of measure. Then he sent unto Queen Morgan le Fay, and to the Queen of North-galis, praying them in his letters that they two sorceresses would set all the country in fire with ladies that were enchantresses, and by such that were dangerous knights, as Malgrin, Breuse Saunce Pité, that by no mean Alisander le Orphelin should escape, but either he should be taken or slain. This ordinance made King Mark for to destroy Alisander.
