Years now passed by, during which Aymon covered himself with glory; for, mounted on Bayard, he was the foremost in every battle, and always struck terror into the hearts of his foes by the mere flash of his blade Flamberge. Thus he fought until his sons attained manhood, and Aya had long thought him dead, when a messenger came to Pierlepont, telling them that Aymon lay ill in the Pyrenees, and wished to see his wife and his children once more.

In answer to these summons Aya hastened southward, and found her husband old and worn, yet not so changed that she could not recognize him. Aymon, sick as he was, rejoiced at the sight of his manly sons. He gave the three eldest the spoil he had won during those many years' warfare, and promised Renaud (Reinold) his horse and sword, if he could successfully mount and ride the former.

[Sidenote: Bayard won by Renaud.] Renaud, who was a skillful horseman, fancied the task very easy, and was somewhat surprised when his father's steed caught him by the garments with his teeth, and tumbled him into the manger. Undismayed by one failure, however, Renaud sprang boldly upon Bayard; and, in spite of all the horse's efforts, kept his seat so well that his father formally gave him the promised mount and sword.

When restored to health by the tender nursing of his loving wife, Aymon returned home with his family. Then, hearing that Charlemagne had returned from his coronation journey to Rome, and was about to celebrate the majority of his heir, Aymon went to court with his four sons.

During the tournament, held as usual on such festive occasions, Renaud unhorsed every opponent, and even defeated the prince. This roused the anger of Charlot, or Berthelot as he is called by some authorities, and made him vow revenge. He soon discovered that Renaud was particularly attached to his brother Alard, so he resolved first to harm the latter. Advised by the traitor Ganelon, Chariot challenged Alard to a game of chess, and insisted that the stakes should be the players' heads.

This proposal was very distasteful to Alard, for he knew that he would never dare lay any claim to the prince's head even if he won the game, and feared to lose his own if he failed to win. Compelled to accept the challenge, however, Alard began the game, and played so well that he won five times in succession. Then Charlot, angry at being so completely checkmated, suddenly seized the board and struck his antagonist such a cruel blow that the blood began to flow. Alard, curbing his wrath, simply withdrew; and it was only when Renaud questioned him very closely that he told how the quarrel had occurred.

Renaud was indignant at the insult offered his brother, and went to the emperor with his complaint. The umpires reluctantly testified that the prince had forfeited his head, so Renaud cut it off in the emperor's presence, and effected his escape with his father and brothers before any one could lay hands upon them. Closely pursued by the imperial troops, Aymon and his sons were soon brought to bay, and fought so bravely that they slew many of their assailants. At last, seeing that all their horses except the incomparable Bayard had been slain, Renaud bade his brothers mount behind him, and they dashed away. The aged Aymon had already fallen into the hands of the emperor's adviser, Turpin, who solemnly promised that no harm should befall him. But in spite of this oath, and of the remonstrances of all his peers, Charlemagne prepared to have Aymon publicly hanged, and consented to release him only upon condition that Aymon would promise to deliver his sons into the emperor's hands, were it ever in his power to do so.

The four young men, knowing their father safe, and unwilling to expose their mother to the unpleasant experiences of the siege which would have followed had they remained at Pierlepont, now journeyed southward, and entered the service of Saforet, King of the Moors. With him they won many victories; but, seeing at the end of three years that this monarch had no intention of giving them the promised reward, they slew him, and offered their swords to Iwo, Prince of Tarasconia.

[Sidenote: Fortress of Montauban.] Afraid of these warriors, yet wishing to bind them to him by indissoluble ties, Iwo gave Renaud his daughter Clarissa in marriage, and helped him build an impregnable fortress at Montauban. This stronghold was scarcely finished when Charlemagne came up with a great army to besiege it; but at the end of a year of fruitless attempts, the emperor reluctantly withdrew, leaving Montauban still in the hands of his enemies.

Seven years had now elapsed since the four young men had seen their mother; and, anxious to embrace her once more, they went in pilgrims' robes to the castle of Pierlepont. Here the chamberlain recognized them and betrayed their presence to Aymon, who, compelled by his oath, prepared to bind his four sons fast and take them captive to his sovereign. The young men, however, defended themselves bravely, secured their father instead, and sent him in chains to Charlemagne. Unfortunately the monarch was much nearer Pierlepont at the time than the young men supposed. Hastening onward, he entered the castle before they had even become aware of his approach, and secured three of them. The fourth, Renaud, aided by his mother, escaped in pilgrim's garb, and returned to Montauban. Here he found Bayard, and without pausing to rest, he rode straight to Paris to deliver his brothers from the emperor's hands.
