But this day King Arthur, as he had promised, rode in shining armor into the field, and fought so valorously that the king of Northgalis and his party had much the worse of the combat.

While the fight thus went on in all its fury, Tristram rode in, still bearing his black shield. Encountering Palamides, he gave him such a thrust that he was driven over his horse's croup. Then King Arthur cried,—

"Knight with the black shield, make ready for me!"

But the king met with the same fate from Tristram's spear that Palamides had done, and was hurled to the earth. Seeing this, a rush of the knights of his party drove back the foe, and Arthur and Palamides were helped to their saddles again.

And now the king, his heart burning with warlike fury, rushed fiercely on Tristram, and struck him so furious a blow that he was hurled from his horse. As he lay there Palamides spurred upon him in a violent rage, and sought to override him as he was rising to his feet. But Tristram saw his purpose and sprang aside. As Palamides rode past he wrathfully caught him by the arm and pulled him from his horse.

"Sword to sword let it be!" cried Tristram.

Palamides, nothing loth, drew his weapon, and so fierce a combat began in the midst of the arena that lords and ladies alike stood in their seats in eagerness to behold it. But at the last Tristram struck Palamides three mighty strokes on the helm, crying with each stroke, "Take this for Sir Tristram's sake!"

So fierce were the blows that Palamides was felled to the earth. Then the king with the hundred knights dashed forward and brought Tristram his horse. Palamides was horsed at the same time, and with burning ire he rushed upon Tristram, spear in rest, before he could make ready to meet him. But Tristram lightly avoided the spear, and, enraged at his repeated treachery, he caught him with both hands by the neck as his horse bore him past, tore him clean from the saddle, and carried him thus ten spears' length across the field before he let him fall.

At that moment King Arthur spurred upon the Cornish champion, sword in hand, and Tristram fixed his spear to meet him, but with a sword-blow Arthur cut the spear in two, and then dealt him three or four vigorous strokes before he could draw. But at the last Tristram drew his sword and assailed the king with equal energy.

This battle continued not long, for the press of battling knights forced the combatants asunder. Then Tristram rode hither and thither, striking and parrying, so that that day he smote down in all eleven of the good knights of King Ban's blood, while all in seats and gallery shouted in loud acclaim for the mighty warrior with the black shield.
