During the night Godfrey made a rapid change in his point of attack, so that in the morning the bewildered Moslems saw the walls threatened where they had made little preparation for defence. A great ravine which thwarted the operations of Raymond was quickly filled by the multitude, who rushed amid the thick rain of arrows, carrying stones, which they threw into it. At daybreak, July 14, 1099, as from a single impulse, the rams began their blows; the catapults and ballistæ filled the air with flying stones and blazing combustibles, and a storm of arrows swept the walls. The assault was met with equal skill and courage, and night fell upon an indecisive engagement. Raymond’s tower had been destroyed, and those of Godfrey and Tancred were injured so that they could not be moved. The 15th of July witnessed a repetition of the carnage. The priests kept up an unceasing procession of prayer around the city, a pious exhibition, which was matched by the appearance on the walls of two Moslem sorceresses, who, as the Christians said, invoked the aid of nature and demons. In vain was the heroism and sacrifices of the crusaders. Their towers were burned and fell, burying their defenders beneath the blazing fagots. The host was beginning to withdraw from the seemingly useless slaughter. Suddenly the cry, “Look! look!” directed all eyes towards the Mount of Olives. The imagination of some one had seen—or his shrewdness, recalling the ruse of the Holy Lance at Antioch, had invented—the apparition of a gigantic knight on the sacred mount, waving his shield. The cry of “St. George! St. George!” rent the air. A timely change in the wind blew the flames and smoke of the Christians’ remaining towers towards the walls. The Moslems were blinded and choked as by the breath of unearthly spirits. Godfrey’s men rushed upon them, drove them from their defences, and, climbing over the wall, pursued them down through the streets of the city. Tancred obtained a similar advantage, and in another torrent poured his contingent over the northern end of the ramparts. The Christians within the city opened the gates, and new tides of slaughter and victory rolled among the houses. Last of all, Raymond carried the battlements which opposed him; thus the various bands met within the city. One rally of the Moslems checked but for an instant the inevitable result.
