King Arthur; and by force Sir Lamorak made that knight to tell all the cause why he bare that horn. Now shalt thou bear this horn, said Lamorak, unto King Mark, or else choose thou to die for it; for I tell thee plainly, in despite and reproof of Sir Tristram thou shalt bear that horn unto King Mark, his uncle, and say thou to him that I sent it him for to assay his lady, and if she be true to him he shall prove her.

And when Sir Tristram saw that there was none other boot but needs that he must die, then said he: Fair lords, remember what I have done for the country of Cornwall, and in what jeopardy I have been in for the weal of you all; for when I fought for the truage of Cornwall with Sir
