It is not impertinent to remark here, that in the Christian armies they were constantly talking about Jerusalem, but that the leaders as constantly directed their efforts and their arms to the acquisition of other conquests. The holy city, situated far from the sea, contained within its walls no other treasures but religious relics and monuments. The maritime cities of Asia could boast of more worldly wealth, and held out far greater advantages to the conquerors; they afforded, likewise, more easy communication with Europe; and if the conquest of Jerusalem sometimes tempted the piety and devotion of the pilgrims, that of cities bordering upon the sea, constantly kept awake the ambition of the maritime and warlike nations of the West. All the sea-coast from Antioch to Ascalon belonged to the Christians; the Mussulmans having only been able to keep possession of Thoron. The garrison of this fortress frequently made incursions into the neighbouring countries, and by continual hostilities, intercepted the communication between the Christian cities. The Crusaders resolved that before they set out for Jerusalem, they would lay siege to the castle of Thoron. This fortress, built by Hugh de Saint-Omer, in the reign of Baldwin II., was situated at some leagues from Tyre, on the summit of a mountain, between the chain of Libanus and the sea. It was only accessible across steep rocks, and by a narrow way bordered by precipices. The Christian army had no machines sufficiently lofty to reach the heights of the walls, and arrows or stones hurled from the foot of the mountain, could not injure the besieged; whilst beams and fragments of rock precipitated from the ramparts, made dreadful havoc among the besiegers. In the early attacks, the Saracens ridiculed the vain efforts of their enemies, and witnessed, almost without danger to themselves, prodigies of valour, and the most murderous inventions of the art of sieges, exercised ineffectually against their walls. But the almost insurmountable difficulties that might have been supposed likely to arrest the progress of the Christians, only redoubled their ardour and courage.[22] They every day made fresh attacks, each day seeming to increase their efforts, and their obstinate bravery was seconded by newly-invented machines of war. With incredible labour, they dug out the earth, and made themselves a way across the rocks; whilst some Saxons, who had worked in the mines of Rammesberg, were employed in opening the flank of the mountain. The Crusaders at length reached the bottom of the ramparts of the fortress; the walls, the foundations of which they demolished, began to shake in various parts, without being struck by the ram, and their fall, which seemed delayed by a miracle, filled the besieged with dread.
