But it passed the skill of man to hold the place against such odds as were brought against them. For the King, having gathered together a great multitude of men, surrounded the castle on all sides, and kept it close for a year and more. Then Reynaud sent a messenger to the King, saying, "I will surrender this fortress and myself also with my brothers, if the King will promise on his part that we shall have our lives and goods." But the King, moved by certain of his counsellors, would promise no such thing. And so for a while the matter stood; neither could the King win the castle, nor could the brethren go free.

After a while there came to King Charles a certain knight, Herneger by name, who said, "Sire, if you will give me this castle of Montanford for my own, and all the goods that are within, and the land about it for five miles, I will deliver to you Reynaud and his brothers within the space of a month from now." "Do this," answered the King, "and you shall have what you ask."

Then Herneger, after he had first disposed a thousand knights in the mountains round about, rode up to the castle gates and said, "I pray you to let me enter, for the King seeks my life. I have something to tell Sir Reynaud that he will be right glad to hear." So the porter opened the gate, and let Sir Herneger pass within.

When Reynaud heard that there was a strange knight in the castle, he came and inquired of his business. Herneger said, "The King seeks my life, because I spake on your behalf." "How does the King fare?" said Reynaud. "Has he good store of victuals?" Herneger answered, "He and his army are well-nigh famished. They will not tarry long in this place, and when they depart you may get much spoil by pursuing them." "That is good to hear," answered Reynaud. "If the King fail of his purpose this time, the opportunity will not soon come again." Then he and his brethren and Herneger the traitor sat down to supper and made good cheer.

When all the knights were fast asleep, the false Herneger rose from his bed and armed himself. Then he cut the cords of the drawbridge, and let it fall, and he slew also the guards that kept watch on the wall. When he had done this, the knights who were disposed upon the mountains came up, being led by Guy of Burgundy, and, finding the gates open, entered in and slew all that they could find. Truly it had gone ill with the four brethren that night but for the horse of Alard that woke them out of their sleep. For some of the guards had been slain, and some who should have watched were drunken, and the brethren had been surprised but for the loud neighing of the horse. When Reynaud saw that the enemy was within the castle, he and his brethren took their places in the tower, and, when the tower was set on fire, they took their stand in a certain pit and defended it right valiantly against all the King's men. After awhile, the other knights that were in the castle taking heart and coming to help them, they drove out the enemy from the castle, and shut the gates and raised the drawbridge. The next day Reynaud said to his brothers, "So far we have done well, and have been delivered beyond all hope. Nevertheless here we may not stay, for all our provision of food has been burnt by fire. Let us depart, therefore, while we can." So they left the castle not without much sorrow. Alard and Guichard were in the vanguard with a hundred knights, and Reynaud and Richard brought up the rear with all the rest of their folk.

That night they passed through the army of the King without hurt or hindrance. But for many days to come they had no rest from their enemies, nor of all that pursued them was there one that did them more damage than did Aymon their father. At last things came to this pass that there was no one left alive of all their followers. Their horses also were in a sore plight, for they had nothing to eat save only such roots as they could find in the ground. Nevertheless the horse Bayard was plump and strong, while the others were so lean and weak that they could scarce stand. A wonderful beast was he in this as in other things, being as well nourished by roots as other horses are wont to be by hay and corn. As for the knights they were ill to see, for their armour was eaten away with rust and their skins dark with hunger and want.

Then said Reynaud to his brothers, "What shall we do? As for myself I had sooner die as becomes a knight than perish here of hunger and cold." Alard said, "My counsel is that we go straight to our lady mother in Ardennes. For though the King and his lords hate us, and even our father is set against us, yet I am persuaded that our mother will not fail us." "You give good counsel," said Reynaud; and to this the other two agreed.

That night the brethren set out, and travelling without stay came to the city of Ardennes. When they were in sight of the walls, Reynaud said to his brethren, "We did ill to take no surety of our father, that he give us not into the King's hands." "Fear not," answered Richard. "I am assured that our lady mother will keep us safe." So they entered the town. But no man knew them, so strange were they to look upon, and the townsfolk asked them, "Of what country are you?" "You are too curious," answered Reynaud, and they rode to the palace.

Now the Duke Aymon chanced to be hawking that day by the river, and the Duchess was in her chamber, where she was wont to sit, in much grief because she had no tidings of her children. After a while she came from her chamber into the hall, where the men sat, but she knew them not. Nay so black were they and foul to look upon that she was in no small fear of them, and was minded for a while to go back to her chamber. But soon she took courage, and greeted the men, saying, "Who are you, Christian men or pagans? Maybe you are doing some penance. Will you have some alms from me or clothing? methinks you need them much. Gladly will I do you this service that God also may have mercy upon my own children." And when she thought of her sons, and how she knew not whether they were alive or dead, she wept aloud.

When Reynaud heard her weep, he was himself greatly moved, and wept also. And the Duchess looking on him more closely was not a little troubled, so that she had almost fallen to the ground in a swoon. But when she came to herself she looked again and lo! there was a scar on his face that he had from a fall when he was a child. So she knew him again, and cried, "O my son Reynaud, how comes it that you are so greatly changed, you that were the fairest knight in all the world?" Then she looked about her, and knew her other sons also, and took them one by one in her arms, both rejoicing and lamenting. So she wept and they wept also.
