Perceval was grieved indeed to see his cousin burnt to ashes; and he beheld the knight who bore the strength of the devil in him, and did not know he could gain revenge. But he charged at him with his sword drawn and dealt him such a blow on his shield that he smashed it right down to the middle where the dragon's head was, and the fire leapt on to the sword and it became red and blazing like the sword of his enemy. And the maiden cried to him:

'By my life, sire, now your sword is as strong as his! Now we shall see what you will do! I have been told in truth that the knight can be killed in only one place and by only one blow, but alas, I cannot tell you how.'

Perceval gazed at his sword, wrapped in the demon's flame, and wondered. Then he struck the knight so fiercely that he made his head bow down to his saddle; the knight drew himself up again, enraged that he could not harm him, and struck Perceval such a terrible blow with his sword that he broke through the hauberk on his right shoulder and cut into the flesh and burned it down to the bone; but as he withdrew his sword Perceval struck him with such force that he cut off his hand and the sword with it.
