Sir Lybius sets out on the adventure: he is derided by the dwarf and
the damsel on account of his youth: they come to the bridge of Perill,
which none can pass without encountering a knight called William de
la Braunch. Sir Lybius is challenged: they just with their spears:
De la Braunch is dismounted: the battle is renewed on foot: Sir
William's sword breaks: he yields. Sir Lybius makes him swear to go
and present himself to K. Arthur, as the first-fruits of his valour.
The conquered knight sets out for K. Arthur's court: is met by three
knights, his kinsmen; who, informed of his disgrace, vow revenge, and
pursue the conqueror. The next day they overtake him: the eldest of
the three attacks Sir Lybius; but is overthrown to the ground. The
two other brothers assault him: Sir Lybius is wounded; yet cuts off
the second brother's arm: the third yields; Sir Lybius sends them all
to K. Arthur. In the third evening he is awaked by the dwarf, who has
discovered a fire in the wood.
