And he was wroth, and he drew his sword, and rushed fiercely upon
him. Then the knight also arose, and drew his sword against Geraint.
And they fought on foot with their swords until their arms struck
sparks of fire like stars from one another; and thus they continued
fighting until the blood and sweat obscured the light from their
eyes. And when Geraint prevailed, the hoary-headed man, and his
wife, and his daughter were glad; and when the knight prevailed, it
rejoiced the Earl and his party. Then the hoary-headed man saw
Geraint receive a severe stroke, and he went up to him quickly, and
said to him, "Oh, chieftain, remember the treatment which thou hadst
from the dwarf; and wilt thou not seek vengeance for the insult to
thyself, and for the insult to Gwenhwyvar the wife of Arthur!" And
Geraint was roused by what he said to him, and he called to him all
his strength, and lifted up his sword, and struck the knight upon the
crown of his head, so that he broke all his head-armour, and cut
through all the flesh and the skin, even to the skull, until he
wounded the bone.

Then the knight fell upon his knees, and cast his sword from his
hand, and besought mercy of Geraint. "Of a truth," said he, "I
relinquish my overdaring and my pride in craving thy mercy; and
unless I have time to commit myself to Heaven for my sins, and to
talk with a priest, thy mercy will avail me little." "I will grant
thee grace upon this condition," said Geraint, "that thou wilt go to
Gwenhwyvar the wife of Arthur, to do her satisfaction for the insult
which her maiden received from thy dwarf. As to myself, for the
insult which I received from thee and thy dwarf, I am content with
that which I have done unto thee. Dismount not from the time thou
goest hence until thou comest into the presence of Gwenhwyvar, to
make her what atonement shall be adjudged at the Court of Arthur."
