Godfrey and the clergy again exerted themselves successfully. They ventured to challenge the Turkish army to a combat of picked troops; and when the proposal was spurned, boldly advanced to attack the whole force. The appearance of the Crusaders, as they marched out of the city, must have been indeed pitiable. Privations had so reduced them, that many had no clothing. Some were nearly fainting from weakness. The barons and knights proceeded chiefly on foot, and camels and asses supplied the place of horses to most of those who rode. Yet the burning zeal of the Christians made the march seem like a triumphal procession; and while the clergy sang hymns of consolation and victory, the soldiers responded with the war-cry, "It is God's will! It is God's will!" The Turkish general, fearing nothing from an army so scantily provided with the means of war, was taken by surprise, but hastily arranged his troops in order of battle. The sight of several natural prodigies, such as the sudden appearance of a meteor, and the favorable direction of the wind, acting upon the superstitious fancy of the Christians, impelled them to extraordinary exertions. The Moslem forces, on the other hand, were weakened by the existence of rivalries and discords in their midst, and lacked the stimulus which the Christians derived from desperation. The attack was commenced by a volley of arrows, followed by a charge of the Turkish and Arabian archers, which the Crusaders not only steadily sustained, but vigorously returned. Godfrey, who commanded their right wing, broke the left wing of the Moslem; but the latter had encompassed the river with a large force, and attacked the Christians in the rear. In spite of the heroism of Godfrey and Tancred, who slaughtered all that ventured to compete with them, and the brave resistance of the whole army, the enemy was evidently gaining ground, when (according to the historians) three horsemen, in brilliant armor, suddenly appeared at the head of a reinforcement descending from the adjacent mountains. Some of the clergy seized on this circumstance to reanimate the Crusaders. "Behold your heavenly succor!" cried a bishop. "Heaven has sent the holy martyrs, George, Demetrius, and Theodore to fight for you!" As he spoke, the whole army seemed inspired with irresistible strength; and, shouting the well-known war-cry, made another vigorous charge which broke the Moslem ranks. The Sultan of Mossoul fled, and his immense force dispersed in the utmost disorder. The extravagant number of 100,000 is said to have fallen in this engagement.
