The march and the intentions of Afdhal soon conveyed terror to Jerusalem. Raymond and the duke of Normandy were again pressed to join the Christian army. Women, old men, and priests with tears conjured the two princes to have pity on the holy city they had delivered. They represented to them the fatal consequences of their inaction, which rendered all the labours of the Crusaders useless, and closed for ever the doors of the East against pilgrims. The voices of all the nations of the West, they told them, would be raised against them, and the blood of the Christians would be on their heads. At last Robert and Raymond allowed themselves to be prevailed upon, and marched with their troops to join Godfrey. The new patriarch desired to follow them, bearing with him the wood of the true cross, the sight of which, like that of the holy lance, would redouble the enthusiasm and the bravery of the Crusaders.

All the Christians in a condition to bear arms quitted Jerusalem to go and fight the Mussulmans. There only remained in the holy city the women, the sick, and a part of the clergy, who, having Peter the Hermit at their head, addressed night and day prayers to Heaven to obtain the triumph of the defenders of the holy places, and the last defeat of the enemies of Christ.

The Christian army, which had at first assembled at Ramla, advanced across a sandy country, and encamped on the banks of the torrent of Sorex, in the plain of Saphœa, or Serfend, situated between Jaffa and Ascalon. The day after the Christians arrived on this plain, they perceived at a distance, towards seven o’clock in the evening, a vast multitude, which they took for the army of the enemy. Two hundred horsemen, who were sent out to reconnoitre, soon returned, however, with the agreeable intelligence that the multitude they had taken for the Egyptian army was nothing but a drove of oxen and camels. So rich a booty at first awakened the avidity of the soldiers, but the prudent Godfrey, who saw nothing in this circumstance but a stratagem of the enemy to throw the Christian army in disorder, forbade his soldiers to leave their ranks. The other leaders, after his example, endeavoured to restrain the men under their command, and all remained firm beneath their standards.

The Crusaders learned from some prisoners they had made, that the enemy were encamped at three leagues from them, and that they were preparing to come and attack the Christian army. Upon receiving this advice, the leaders made their dispositions to receive the infidels. The army was drawn up in nine divisions, and formed a sort of square battalion, so as to be able at need, to face the enemy at all points. The Crusaders passed the night under arms. On the following morning ’it was the eve of the Assumption) the heralds announced by sound of trumpet that they were about to give battle to the infidels. At break of day the Crusaders received the benediction of the patriarch of Jerusalem. The wood of the true cross was carried through the ranks, and shown to the soldiers as a certain pledge of victory. The leaders then gave the signal, all the ensigns were unfurled, and the army marched to meet the Saracens.

The nearer the Christians approached the army of Egypt, the more were they filled with confidence and hope. Their drums, cymbals, hymns, and war-songs animated them to the fight. They marched towards the enemy, says Albert d’Aix, as to a joyous feast. An emir of Palestine, who followed the army as an auxiliary, could not sufficiently admire, if we may believe historians, this joy of the soldiers of the cross at the approach of danger. He came to express his surprise to the king of Jerusalem, and swore before him to embrace a religion which could give so much strength and bravery to its defenders.

The Christians soon arrived in the plain of Ascalon. This immense plain is bounded on the east and south by mountains, and extends on the west to the sea. On the coast was situated the city of Ascalon, over which the Mussulman standards floated. At the extremity of the plain the army of Egypt was drawn up, with the sea and the mountains behind it. The Crusaders advanced in two lines; the count of Thoulouse commanded the right wing, the two Roberts and Tancred were placed at the left. Godfrey commanded a body of reserve, which was at the same time to keep the garrison of Ascalon in check and fight with the army of Egypt.

Whilst the Christian army was thus marching in battle array, the drove of oxen and camels that they had met on their route came to their rear, and followed all their movements. The confused noise of these animals, mingled with the sound of the drums and trumpets, and the clouds of dust which arose under their steps, caused them to be taken for squadrons of horse, and the Mussulmans were persuaded that the Christian army was more numerous than their own. They were drawn up in two lines, as the Crusaders were. The Turks from Syria and Bagdad were on the right; the Moors and Egyptians on the left; the emir Afdhal occupied the centre with the main body of the Egyptian forces. This army covered an immense space, and, says Foulcher de Chartres, like a stag who projects his branching horns, it extended its wings to envelop the Christians; but a sudden terror rendered it motionless.

In vain the emir endeavoured to rouse the courage of his soldiers. They fancied that millions of Crusaders had arrived from the West; they forgot both their oaths and their threats, and only remembered the fate of the Mussulmans immolated after the conquest of Jerusalem.

Before engaging, all the Crusaders, fully armed, fell on their knees to implore the protection of Heaven; and rising full of ardour and hope, marched against the Saracens. If the most truthful historians are to be believed, they had not more than fifteen thousand foot and five thousand horse. When they had arrived within bow-shot, the foot-soldiers made several discharges of javelins, at the same time the cavalry, increasing their speed, precipitated themselves upon the enemy’s ranks. At this first charge the duke of Normandy, the count of Flanders, and Tancred broke through the centre of the Egyptians. Duke Robert, followed by his bravest knights, penetrated to the place where Afdhal fought, and got possession of the great standard of the infidels. The foot-soldiers followed the horse into the mêlée, and cast away their bows and javelins to make use of sword and lance, arms much more terrible to the Mussulmans.
