When Sir Palomides saw that Sir Tristram was disguised, he thought to shame him: he rode to a knight who was sorely wounded and who sat under a tree a good way from the field.
"Sir knight," said Sir Palomides, "I pray you to lend me your armor and your shield, for mine is overly well known in this field; that hath done me great damage. Ye shall have my armor and my shield which are as good as yours."
"I will well," said the knight, "that ye have my armor and my shield. If they may do you any avail, I am well pleased."
So Sir Palomides armed hastily in that knight's armor and his shield, which shone like any crystal or silver, and he came riding into the field. Neither Sir Tristram nor any of Sir Tristram's or King Author's party recognized Sir Palomides. Just as he came into the field Sir Tristram smote down three knights, right in the sight of Sir Palomides. Then he rode against Sir Tristram and each met the other with great spears, so hard that the spears burst up to their hands; then they dashed together with swords eagerly. Sir Tristram marvelled what knight it was who did battle so mightily with him. Then he was wroth, for he felt that knight to be passing strong, and he deemed he could not have ado with the remnant of the knights because of the strength of Sir Palomides.
