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

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.

So that day Sir Clam
