Then the King of the Hundred Knights and those of North Wales set upon twenty knights who were of Sir Lancelot's kin, who fought all together, none failing the others. When Sir Tristram beheld their nobleness and valor, he marveled much. "Well may he be valiant and full of prowess," said he, "who hath such noble knights for kindred." So, when he had looked on them awhile, he thought it shame to see two hundred men assailing twenty, and riding to the King of a Hundred Knights, he said, "I pray thee, Sir king, leave your fighting with those twenty knights, for ye be too many and they be too few. For ye shall gain no honor if ye win, and that I see verily ye will not do unless ye slay them; but if ye will not stay, I will ride with them and help them."
"Nay," said the king, "ye shall not do so; for full gladly I will do your courtesy," and with that he withdrew his knights.
Then Sir Tristram rode his way into the forest, that no man might know him. And King Arthur caused the heralds to blow that the tourney should end that day, and he gave the King of North Wales the prize, because Sir Tristram was on his side. And in all the field there was such a cry that the sound thereof was heard two miles away—"The knight with the black shield hath won the field."
"Alas!" said King Arthur, "where is that knight? it is shame to let him thus escape us." Then he comforted his knights, and said, "Be not dismayed, my friends, howbeit ye have lost the day; be of good cheer; to-morrow I myself will be in the field, and fare with you." So they all rested that night.
And on the morrow the heralds blew unto the field. So the King of North Wales and the King of a Hundred Knights encountered with King Carados and the King of Ireland, and overthrew them. With that came King Arthur, and did mighty deeds of arms, and overthrew the King of North Wales and his fellows, and put twenty valiant knights to the worse. Anon came in Sir Palomedes, and made great fight upon King Arthur's side. But Sir Tristram rode furiously against him, and Sir Palomedes was thrown from his horse. Then cried King Arthur, "Knight of the Black Shield, keep thyself." And as he spake he came upon him, and smote him from his saddle to the ground, and so passed on to other knights. Then Sir Palomedes having now another horse rushed at Sir Tristram, as he was on foot, thinking to run over him. But he was aware of him, and stepped aside, and grasped Sir Palomedes by the arms, and pulled him off his horse. Then they rushed together with their swords, and many stood still to gaze on them. And Sir Tristram smote Sir Palomedes with three mighty strokes upon the helm, crying at each stroke, "Take this for Sir Tristram's sake," and with that Sir Palomedes fell to the earth.
Anon the King of North Wales brought Sir Tristram another horse, and Sir Palomedes found one also. Then did they joust again with passing rage, for both by now were like mad lions. But Sir Tristram avoided his spear, and seized Sir Palomedes by the neck, and pulled him from his saddle, and bore him onward ten spears' length, and so let him fall. Then King Arthur drew forth his sword and smote the spear asunder, and gave Sir Tristram two or three sore strokes ere he could get at his own sword. But when he had it in his hand he mightily assailed the king. With that eleven knights of Lancelot's kin went forth against him, but he smote them all down to the earth, so that men marveled at his deeds.
And the cry was now so great that Sir Lancelot got a spear in his hand, and came down to assay Sir Tristram, saying, "Knight with the black shield, make ready." When Sir Tristram heard him he leveled his spear, and both stooping their heads, they ran together mightily, as it had been thunder. And Sir Tristram's spear brake short, but Sir Lancelot struck him with a deep wound in the side and broke his spear, yet overthrew him not. Therewith Sir Tristram, smarting at his wound, drew forth his sword, and rushing at Sir Lancelot, gave him mighty strokes upon the helm, so that the sparks flew from it, and Sir Lancelot stooped his head down to the saddle-bow. But then Sir Tristram turned and left the field, for he felt his wound so grievous that he deemed he should soon die. Then did Sir Lancelot hold the field against all comers, and put the King of North Wales and his party to the worse. And because he was the last knight in the field the prize was given him.
But he refused to take it, and when the cry was raised, "Sir Lancelot hath won the day," he cried out, "Nay, but Sir Tristram is the victor, for he first began and last endured, and so hath he done each day." And all men honored Lancelot more for his knightly words than if he had taken the prize.
This was the tournament ended, and King Arthur departed to Caerleon, for the Whitsun feast was now nigh come, and all the knights adventurous went their ways. And many sought Sir Tristram in the forest whither he had gone, and at last Sir Lancelot found him, and brought him to King Arthur's court, as hath been told already.
