Then the Lady Blanchefleur smiled upon Sir Percival and she said:  “Percival, I will gladly entrust my life and safety into thy keeping, for I too have great dependence in thy knighthood.”

So straightway Sir Percival armed himself, and when he was in all wise prepared he went forth to that battle with a heart very full of great courage and hope.

There he found Sir Clamadius still parading in that meadow beneath the walls, awaiting the coming of his opponent.

[Sidenote:  Sir Percival and Sir Clamadius do battle] Meanwhile many folk came and stood upon the walls of the castle to behold that encounter, whilst each knight took such stand as appeared good to him.  Then, when they were in all wise prepared, each knight drave spurs into his horse and rushed himself against the other with most terrible and fierce violence.  Therewith they met in the very midst of the course with an uproar like to thunder that echoed back from the flat walls of the castle.

In that encounter the spear of Sir Percival held, but the spear of Sir Clamadius was riven into splinters.  And so, Sir Percival riding forward with furious violence, Sir Clamadius was overthrown, horse and man, with such violence that he lay there upon the ground as though he were dead.

Then all those upon the walls shouted aloud with a great noise of rejoicing, whilst those of the party of Sir Clamadius gave lamentation in the same degree.

[Sidenote:  Sir Clamadius yields himself] But Sir Percival voided his saddle in haste, and ran to where Sir Clamadius lay.  And Sir Percival rushed the helmet off from the head of Sir Clamadius, and he catched him by the hair of the head, and he raised his sword on high with intent to finish the work he had begun.  Therewith Sir Clamadius aroused himself unto his danger, and he cried in a very piercing voice:  “Messire, I beseech thee of thy knighthood to spare my life!”

“Well,” said Sir Percival, “since you ask me upon my knighthood, I cannot refuse you, for so I was taught by the noble knight, Sir Launcelot, to refuse no boon asked upon my knighthood that I was able to grant.  But I will only spare your life upon one condition, and that is this:  That you disarm yourself in all wise, and that you go without armor to the court of King Arthur.  There you shall deliver yourself as a servant unto a damsel of King Arthur’s court, hight Yelande, surnamed the Dumb Maiden.  Her you are to tell that the youth who slew Sir Boindegardus hath sent you unto her as a servant.  And you are to say to Sir Kay, the Seneschal of King Arthur, that the young knight Percival will in a little while come to repay that buffet he gave to the damoiselle Yelande aforesaid.”

So said Sir Percival, and Sir Clamadius said:  “It shall be done in all wise as you command, if so be you will spare my life.”  Then Sir Percival said:  “Arise”; and Sir Clamadius arose; and Sir Percival said:  “Go hence”; and therewith Sir Clamadius departed as Sir Percival commanded.
