When they had calmed themselves a little, Balan said, “I had no thought of meeting you here; I had supposed you were still in prison, for a knight that I met at the castle of Four Stones told me how you had been imprisoned by the king.  I came this way hoping to serve you.”

Balin in reply told him of his adventures until the time they met, and added, “Truly I am very sad that King Arthur is displeased with me, for he is the most worshipful knight that reigneth on this earth.  Now I mean to regain his love or perish in the attempt.  King Rience is even now besieging the Castle Terrabil, and thither do I ride to see what I can do against him.”

“I will go with you,” said Balan, “and we will help each other as true knights and good brethren ought to do.”

As they talked they saw coming toward them a misshapen old man.  This was Merlin in a strange disguise, though the brothers did not know him.

“Ah, Balin,” said the old dwarf, “too ready are you to strike in anger, for here you have slain one of the noblest knights of Arthur’s court, and his kinsmen will follow you through the world till they have slain you.”

“As for that,” said Balin, “I have little fear, but I regret beyond words that I have displeased my lord, King Arthur.”

“Be that as it may,” answered Merlin, “you have given the saddest blow ever struck; and yet worse is to come, for with that same sword will you slay your brother.”

“If I believed that,” the sad knight replied, “I should kill myself now to prove you a liar.”

At that moment the crippled old man vanished suddenly, and the brothers saw Merlin in his own person riding toward them.

“Where are you going?” inquired Merlin.

“At present we have little to do and ride as we please.”

“I can tell you where you are going,” said the magician.  “You go to meet King Rience, but your journey will be a failure unless you are guided by my counsel.”

“Ah, Merlin,” said Balin, “we will be ruled by you.”

“Come on then; but see that you fight manfully, for you will need all your strength and valor.”

“Fear not,” they both exclaimed.  “We will do all that men can do.”

“Then,” said the magician, “conceal yourselves here in the woods behind the leaves.  Hide your horses and rest in patience, for soon will Rience with sixty of his best knights come this way.  You can fall upon them from ambush and easily destroy them.”

It happened just as Merlin had predicted, and the brothers soon saw the sixty knights riding down the lane.

“Which is Rience?” asked Balin.

“There,” said he, “the knight that rides in the midst—­that is Rience.”

The brothers waited till Rience was opposite them, and then they rushed upon him and bore him down, wounding him severely.  Wheeling from the charge they fell upon the followers of Rience and smote them to right and left, so that many fell dead or wounded and the remainder broke into flight.
