With that came Sir Bleoberis, and Sir Tristram gave him such a buffet that down he laid his head; and then he caught him so sore by the helm that he pulled him under his horse’s feet. And then King Arthur blew to lodging. Then Sir Tristram departed to his pavilion, and Sir Dinadan rode with him; and Sir Persides and King Arthur then, and the kings upon both parties, marvelled what knight that was with the black shield. Many said their advice, and some knew him for Sir Tristram, and held their peace and would nought say. So that first day King Arthur, and all the kings and lords that were judges, gave Sir Tristram the prize; howbeit they knew him not, but named him the Knight with the Black Shield.
