These bravadoes had no effect upon Louis; the Moors inspired no terrors, and did not conceal their own fears at the sight of the Crusaders. Never venturing to face their enemy, their bands, sometimes scattered, hovered about the Christian army, seeking to surprise wanderers from the camp; and sometimes united, they fell upon the advanced posts, launched a few arrows, just exhibited their naked swords, and then relied upon the swiftness of their horses for safety. They often had recourse to treachery: three of them came to the Christian camp, and said they wished to embrace the Christian faith; and a hundred others followed them, expressing the same intention. They were received with open arms; but, watching their opportunity, they fell, sword in hand, upon some unguarded Frenchmen; but upon the alarm being given, were surrounded, and most of them killed, The three first comers threw themselves on their knees and implored the compassion of the chiefs. The contempt such enemies were held in obtained their pardon, and they were kicked out of the camp. Rendered bold by the inactivity of the Christian army, the Mussulmans at length presented themselves several times in the plains. Nothing would have been more easy than to attack and conquer them, but Louis had resolved to await the arrival of his brother, Charles of Anjou, before he began the war: a fatal resolution, that ruined everything. The Sicilian monarch, who had principally promoted this ill-starred expedition, was doomed to complete by his delay the evil he had commenced by his counsels. So much time being afforded them, the Mussulmans flocked from all parts of Africa to defend the cause of Islamism. Thus the army of the Moors became formidable; but it was not this crowd of Saracens that the Crusaders had most to fear. Other dangers, other misfortunes threatened them: the army wanted water; they had none but salt provisions; the soldiers could not support the climate of Africa; winds prevailed, which, coming from the torrid zone, appeared to be accompanied by a devouring flame. The Saracens on the neighbouring mountains stirred up the sand with certain instruments, and the hot dust fell in clouds upon the plain where the Christians were encamped. At length dysentery, the malady of hot climates, attacked them, and the plague, which seemed to spring up of itself from the burning soil, spread its contagion among them. The men were under arms night and day, not to defend themselves against an enemy who always ran away, but to avoid surprises. Most of the Crusaders sunk under the awful combination of fatigue, famine, and sickness. Some of the most renowned warriors of France fell a prey to the one or the other. They could not bury the dead; the ditches of the camp were filled with carcasses, thrown in _pêle-mêle_, which added to the corruption of the air and the spectacle of the general desolation.
