Whilst matters were going on thus in the camp, the most profound silence reigned around the walls of Jerusalem, only broken by the voices issuing from hour to hour from the minarets of the mosques, to call the faithful to prayer. The infidels flocked in crowds to their temples to implore the protection of their prophet, and swore by the mysterious stone of Jacob to defend a city, which they called _the house of God_. The besieged and the besiegers were stimulated by the same ardour to fight and shed their blood: the former to preserve Jerusalem, the latter to make the conquest of it. The hatred which animated them was so violent, that, during the whole of the siege, no deputed Mussulman came to the camp of the Christians, and the Christians never once deigned to summon the garrison to surrender. Between such enemies, the shock must be terrible and the victory implacable. It was resolved, in a council of the leaders, to take advantage of the enthusiasm whilst it was at its height, and execute the assault. As the Saracens displayed a great number of machines on the sides of the city which appeared to be most threatened by the Christians, it was determined to change the dispositions of the siege, and that the principal attack should be directed towards the points where the enemy had made no preparations for defence. During the night Godfrey removed his quarters to the eastward, towards the gate of Cedar, not far from the valley in which Titus encamped when his soldiers penetrated into the galleries of the temple. The rolling tower, and the other machines of war which the Duke of Lorraine had caused to be built, were transported, with incredible efforts, in front of the walls he wished to attack. Tancred and the two Roberts drew up their machines between the gate of Damascus and the angular tower, which was afterwards called _Tancred’s Tower_. At break of day the Saracens, on beholding these new dispositions, were seized with astonishment and terror. The Crusaders might have taken advantage of the confusion inspired in this change; but upon a steep ground it was difficult to bring their machines close to the walls. Raymond, in particular, who was charged with the attack on the south, found himself separated from the ramparts by a ravine, which it was necessary for him to fill up. He caused it to be proclaimed by a herald that he would pay a denier to every person who would cast three stones into it. A crowd of people instantly flocked to the aid of the soldiers,--a shower of darts and arrows from the ramparts producing no effect upon the ardour and zeal of the labourers. At length, by the end of the third day, all was completed, and the leaders gave the signal for a general assault.
