Towards the close of the year, after being joined by a body of English volunteers, the French monarch resolved to march to Cairo and attack the sultan in the heart of his kingdom. But the floods of the Nile, and the intersection of the country by numerous canals, occasioned a second time the loss of a brave army. Famine and disease, too, aided the sword of the enemy, till at length the victors of Damietta were compelled to sue for a peace which they could no longer obtain. A retreat was ordered; but those who attempted to escape by the river were taken prisoners, and the fate of such as proceeded by land was equally disastrous. While they were occupied in constructing a bridge over a canal, the Saracens entered the camp and murdered the sick. The valiant king, though oppressed with the general calamity of disease, sustained boldly the shock of the enemy, throwing himself into the midst of them, resolved to perish rather than desert his troops. One of his attendants succeeded at length in drawing him from the presence of the foe, and conducted him to a village, where he sunk under his wounds and fatigue into a state of utter insensibility. In this miserable condition he was overtaken by the Moslems, who announced to him that he was their captive. One of his brothers, the gallant Artois, had already fallen in battle, but the two others, Anjou and Poictiers, with all the nobility, fell into the hands of the enemy. The sultan did not abuse his victory, nor seek to impose upon Louis terms which a sovereign could not grant without forfeiting his honour. He agreed to accept a sum equivalent to five hundred thousand livres for the deliverance of the army, and the town of Damietta as a ransom for the royal person. Peace was to continue ten years between the Mussulmans and the Christians; while the Franks were to be restored to those privileges in the kingdom of Jerusalem which they had enjoyed previous to the recent invasion of the French. The repose which succeeded this treaty was interrupted by the murder of the sultan, who fell a victim to the jealousy, of the Mamlouks; but after a few acts of hostility too insignificant to be recorded, the emirs renewed, with a few modifications, the basis of the agreement on which the peace was established. Louis himself made a narrow escape from the sanguinary intrigues of those military slaves who had imbrued their hands in the blood of their own master. They declared that, as they had committed a sin by destroying their sultan, whom, by their law, they ought to have guarded as the apple of their eye, their religion would be violated if they suffered a Christian king to live. But the other chiefs, more honourable than the Mamlouks, disdained to commit a crime under any such pretext; and the French monarch, accordingly, was allowed to accompany the poor remains of his army to the citadel of Acre.
