His troops were strictly enjoined to await the first onset of the enemy, to spare their flying brethren, and to respect the bodies of the dead, and the chastity of the female captives. He generously proposed to save the blood of the Moslems by a single combat; but his trembling rival declined the challenge as a sentence of inevitable death. The ranks of the Syrians were broken by the charge of a hero who was mounted on a piebald horse, and wielded with irresistible force his ponderous and two-edged sword. As often as he smote a rebel, he shouted the Allah Acbar, "God is victorious!" and in the tumult of a nocturnal battle, he was heard to repeat four hundred times that tremendous exclamation. The prince of Damascus already meditated his flight; but the certain victory was snatched from the grasp of Ali by the disobedience and enthusiasm of his troops. Their conscience was awed by the solemn appeal to the books of the Koran which Moawiyah exposed on the foremost lances; and Ali was compelled to yield to a disgraceful truce and an insidious compromise. He retreated with sorrow and indignation to Cufa; his party was discouraged; the distant provinces of Persia, of Yemen, and of Egypt, were subdued or seduced by his crafty rival; and the stroke of fanaticism, which was aimed against the three chiefs of the nation, was fatal only to the cousin of Mahomet. In the temple of Mecca, three Charegites or enthusiasts discoursed of the disorders of the church and state: they soon agreed, that the deaths of Ali, of Moawiyah, and of his friend Amrou, the viceroy of Egypt, would restore the peace and unity of religion. Each of the assassins chose his victim, poisoned his dagger, devoted his life, and secretly repaired to the scene of action. Their resolution was equally desperate: but the first mistook the person of Amrou, and stabbed the deputy who occupied his seat; the prince of Damascus was dangerously hurt by the second; the lawful caliph, in the mosch of Cufa, received a mortal wound from the hand of the third. He expired in the sixty-third year of his age, and mercifully recommended to his children, that they would despatch the murderer by a single stroke. The sepulchre of Ali was concealed from the tyrants of the house of Ommiyah; but in the fourth age of the Hegira, a tomb, a temple, a city, arose near the ruins of Cufa. Many thousands of the Shiites repose in holy ground at the feet of the vicar of God; and the desert is vivified by the numerous and annual visits of the Persians, who esteem their devotion not less meritorious than the pilgrimage of Mecca.
