Now, whilst Sir Ewaine stood listening in that wise, all bewitched by the singing of those birds, he was aware of one who came riding very rapidly toward him across the plain. And as that rider drew nigh unto Sir Ewaine, he beheld that he was a knight clad all in black armor and seated upon a great charger which was entirely black and which was hung with trappings as black as any raven. And the knight bore a shield which was altogether black and without any device whatsoever. And he was of a very terrible appearance, being huge of form and violent and fierce in his advance.
This black knight, when he had come close to that place where Sir Ewaine awaited him, cried out in a great voice: "Sir Knight, why didst thou come hither to meddle with my fountain? Know thou that thou hast brought a great deluge upon all this land so that thou hast wrought great damage to us who are the people thereof. But now thou shalt pay very dearly for the injury thou hast done. Prepare thyself straightway for battle!"
Unto this Sir Ewaine made reply: "Sir Knight, I wist not that in throwing water upon yonder slab I was doing injury to thee or to any one. Nevertheless, I am ready to meet thee in battle as thou dost make demand." Therewith Sir Ewaine dressed his shield and his spear and took his station in the meadow near the fountain and beside the lake, and put himself in such array for defence as he was able.
Sir Ewaine doeth battle with the Knight of the Fountain.
So when they both had prepared themselves in all ways they let go their horses the one against the other, in very violent assault, rushing together like a whirlwind. And so they met together in the midst of the course with an uproar as of thunder; the one smiting against the other with such violence that the spear of each was burst all into pieces unto the very truncheon thereof. And in that assault both knights would assuredly have been overthrown excepting for the wonderful address of each. For each drave spur into steed and shouted aloud so that each charger recovered his feet and fell not. Then each knight threw away the truncheon of his spear and each drew his sword and straightway fell to battle with might and main. And in that combat each knight gave the other many sore buffets and, for a long while, no one could have told how that encounter was like to go.
But at last Sir Ewaine waxed very furious with the opposition of that other knight, wherefore he arose in his stirrups and lashed at that black knight such a buffet that nor guard nor shield nor helm could withstand the stroke. For under that blow the black Knight of the Fountain reeled in his saddle as though he would fall from his horse. Then he drooped his shield and hung his head full low and catched at the horn of his saddle as though to stay himself from falling. Herewith Sir Ewaine lashed another buffet at him, and with that blow the sword of Sir Ewaine pierced through the helmet of the black knight and deep into his brain pan and with that stroke the black knight received his mortal hurt.
Then Sir Ewaine, perceiving that the black knight was so sorely hurt, repented him of what he had done in the heat of his battle and stayed his hand, though all too late. And he cried out: "Sir Knight, I fear me that I have given thee a very woeful hurt. I repent me of that, so yield thou thyself to me, and forthwith I will look to thy wound and will give thee such ease as I may."
The Knight of the Fountain fleeth from Sir Ewaine.
But to this the black Knight of the Fountain made no reply. Otherwise he immediately wheeled his horse about, and set spurs to flank, and drove away with all speed from that place. And so rapidly did he race away from the field of battle that he appeared to fly, as it were, like to the shadow of a bird across the plain.
Sir Ewaine pursueth the Black Knight.
