"Sir knight," said [the king], "where had ye that helm?"
"What would ye?" said Sir Dinadan.
"For I will have ado with thee," said the king, "for the love of her that owned that helm, and therefore keep you."
So they departed and came together with all the mights of their horses; and there the king with the hundred knights smote Sir Dinadan, horse and all, to the earth; and then he commanded his servant, "Go and take thou his helm off, and keep it."
So the varlet went to unbuckle his helm.
"What helm? What wilt thou do?" said Sir Tristram; "leave that helm."
"To what intent," said the king, "will ye, sir knight, meddle with that helm?"
"Wit you well," said Sir Tristram, "that helm shall not depart from me, or it be dearer bought."
"Then make you ready," said [the king] unto Sir Tristram.
So they hurtled together, and there Sir Tristram smote him down over his horse's tail. And then the king arose lightly, and gat his horse lightly again, and then he struck fiercely at Sir Tristram many great strokes. And then Sir Tristram gave [the king] such a buffet upon the helm that he fell down over his horse, sore stunned.
