Defence was impossible. He had not half enough men to guard the walls and repel assaults. It would have been folly to stand a siege, yet Theodomir did not care to surrender except on favorable terms, and therefore adopted a shrewd stratagem to deceive the enemy in regard to his strength. To the surprise of the Arab leader the walls of the town, which he had thought half garrisoned, seemed to swarm with armed and bearded warriors, far too great a force to be overcome by a sudden dash. In the face of so warlike an array, caution awoke in the hearts of the assailants. They had looked for an easy victory, but against such numbers as these assault might lead to severe bloodshed and eventual defeat. They felt that it would be necessary to proceed by the slow and deliberate methods of a regular siege. While Abdul-Aziz was disposing his forces and making heedful preparations for the task he saw before him, he was surprised to see the principal gate of the city thrown open and a single Gothic horseman ride forth, bearing a flag of truce and making signals for a parley. A safe-conduct was given him, and he was led to the tent of the Moslem chief. "Theodomir has sent me to negotiate with you," he said, "and I have full power to conclude terms of surrender. We are abundantly able to hold out, as you may see by the forces on our walls, but as we wish to avoid bloodshed we are willing to submit on honorable terms. Otherwise we will defend ourselves to the bitter end." The boldness and assurance with which he spoke deeply impressed the Arab chief. This was not a fearful foe seeking for mercy, but a daring antagonist as ready to fight as to yield. "What terms do you demand?" asked Abdul-Aziz. "My lord," answered the herald, "will only surrender on such conditions as a generous enemy should grant and a valiant people receive. He demands peace and security for the province and its people and such authority for himself as the strength of his walls and the numbers of his garrison justify him in demanding." The wise and clement Arab saw the strength of the argument, and, glad to obtain so rich a province without further loss of life, he assented to the terms proposed, bidding the envoy to return and present them to his chief. The Gothic knight replied that there was no need of this, he having full power to sign the treaty. The terms were therefore drawn up and signed by the Arab general, after which the envoy took the pen and, to the astonishment of the victor, signed the name of Theodomir at the foot of the document. It was the Gothic chief himself.
