Three months of fruitless effort passed, and the host of the Crusaders began to suffer from lack of food. They dared not venture far to look for it, for the Turks were always on the watch, and no man could with safety leave his post.

Finding, moreover, that the Crusaders generally got the worst of it when the Turks made a sally from the city, the native Christians of the country transferred the provisions they had been wont to bring to the former, to those from whom they now believed they would reap the greater advantage in the near future.

Then hope began to fail the besiegers, whose camp, owing to the heavy rain, had now become a fever-haunted swamp. One or two of the meaner-spirited leaders tried to get quietly away with their troops; even Peter the Hermit lost heart, and would have deserted the host had he not been forcibly turned back by Tancred.

Meantime the Seljukian Turks had been expelled by the Saracens from Jerusalem and Tyre, and the Caliph of the latter now sent envoys to the leaders of the Crusade, of whose evil condition he had been informed, to express his surprise that the Christians, while rightly warring against the fierce Seljuks, should desire to attack Jerusalem also. He promised, moreover, to extend his protection for a whole month to any peaceable pilgrims who should wish to visit the Holy City, on condition that the Crusaders would acknowledge his supremacy in Syria; and he warned them that if they refused his terms his whole power would forthwith be directed against them.

The Caliph's envoys expected to find the camp in sorry plight; but, to their surprise, they were entertained in lordly fashion, and found every sign of prosperity and plenty. They were sent back with an absolute refusal to relinquish the right of Christendom over the whole of Palestine, and quite in ignorance of the terrible straits in which the army really stood, in spite of its outward appearance of prosperity. It was true that when the enemy attacked them in the open, the Crusaders were more than able to hold their own; it was the hopeless inaction, the dread of disaffection in the camp, and the pangs of actual famine that were sapping the courage of the besiegers; and now the news that an immense army, led by the Sultan of Persia, was coming to the relief of the city was the last and most crushing blow.

At this crisis, Bohemond, whose movements had for some time been full of mystery, assembled the leaders and asked for a solemn oath from them that the man who succeeded in taking the city should be its future ruler. Very unwillingly they gave their consent, upon which Bohemond revealed the fact that he had for some time past been in communication with an officer of the city guard, who was in the full confidence of the governor, and could obtain possession of Antioch whenever he wished.

So, on the 2nd of June 1098, nearly six months after the beginning of the siege, a little band of Crusaders quietly approached the gate of St George and gave their signal. A rope ladder was silently lowered from the top of the wall, up which Bohemond promptly sprang. But at the summit he found himself alone; for in their distrust of him, the rest had waited to see what would happen. The sight of his safe arrival gave them confidence, and about sixty swarmed up the ladder, which then broke. Those at the top, however, undeterred by their isolated position on the walls of a hostile city, found their way in the darkness to a gate, and broke it open. In rushed the invading army with their battle-cry of "Deus vult! Deus vult!" and the city, taken quite unawares, was soon in their hands.

The sun rose on the third day of June upon a city red with blood, the governor of which had paid with his head for his courage in holding out so long. Dawn also revealed the blood-red banner of Bohemond floating from the highest tower. Only the citadel, by a strange oversight on the conqueror's part, was still in the hands of a small body of Turks.

The news of the fall of Antioch gave rise to general alarm throughout the East. The followers of Sultan David, their former foe, joined with those of the Sultan of Persia against the Crusaders, and led by the famous general Kerboga, flung themselves against the walls of the city. Flushed with success, the victors had overlooked the fact that there was scarcely any food within the gates, and also they had allowed their means of access to the Mediterranean ports to be cut off. Within a few days the besiegers were the besieged and in far worse plight than before. Many, even of the nobles, were seized with panic, and letting themselves down by ropes from the walls, fled to the sea-coast. Even Stephen of Chârtres, son-in-law of William the Conqueror, who, through illness, had retired before the city fell, and who was now entreated to return with his troops to its aid, lost his nerve when he looked down from the hills upon the sea of tents that lay before the walls. Not only did he rapidly retreat, but meeting the Emperor Alexios marching with an army to aid the Crusaders, he actually prevailed upon the latter, not at all against his will, to retire from the hopeless conflict.

With foes outside the walls, and foes holding the citadel within, the unfortunate host of Crusaders was indeed in evil case.
