Ganelon answered, "Nay; what folly is this! Heed wiser counsel. Send back the hostages to Charles with me. Then will Charles gather his host together, and depart out of Spain, and go to Aachen, there to await the fulfilment of thy covenant. But he will leave his rear-guard of twenty thousand, together with Roland and Oliver and the Twelve, to follow after him. Fall thou on these with all thy warriors; let not one escape. Destroy them, and thou mayest choose thy terms of peace, for Charles will fight no more. The rear-guard will take their journey by the pass of Siza, along the narrow Valley of Roncesvalles. Wherefore surround the valley with thy host, and lie in wait for them. They will fight hard, but in vain." Then Marsilius made him swear upon the book of the law of Mohammed, and upon his sword handle, that all should happen as he had said. Thus Ganelon did the treason. And Marsilius gave Ganelon rich presents of gold and precious stones, and bracelets of great worth. He gave him also the keys of his city of Zaragoz, that he should rule it after these things were come to pass, and promised him ten mules' burden of fine gold of Arabia. So he sent Ganelon again to Charles, and with him twenty hostages of good faith. When Ganelon came before Charles, he told him King Marsilius would perform all the oath which he sware, and was even now set out upon his journey to do his fealty, and pay the price of peace, and be baptized. Then Charles lifted up his hands toward Heaven, and thanked God for the prosperous ending of the war in Spain. THE GREAT BATTLE OF RONCESVALLES By Sir George W. Cox In the morning the king arose and gathered to him his host to go away to keep the feast of Saint Michael at Aachen, and to meet Marsilius there. And Ogier the Dane made he captain of the vanguard of his army which should go with him. Then said the king to Ganelon, "Whom shall I make captain of the rear-guard which I leave behind?" Ganelon answered, "Roland; for there is none like him in all the host." So Charles made Roland captain of the rear-guard. With Roland there remained behind, Oliver, his dear comrade, and the twelve peers, and Turpin the archbishop, who for love of Roland would fain go with him, and twenty thousand proven warriors. Then said the king to his nephew, "Good Roland, behold, the half of my army have I given thee in charge. See thou keep them safely." Roland answered, "Fear nothing. I shall render good account of them," So they took leave of one another, and the king and his host marched forward till they reached the borders of Spain. And ever as the king thought upon his nephew whom he left behind, his heart grew heavy with an ill foreboding. So they came into Gascoigny and saw their own lands again. But Charles would not be comforted, for being come into France he would sit with his face wrapped in his mantle, and he often spake to Duke Naymes, saying he feared that Ganelon had wrought some treason.
