“Raymond of Toulouse, who, cognisant of the whole plan, had been left behind with the main body of the army, heard at this instant the signal horn, which announced that an entry had been effected, and, leading on his legions, the town was attacked from within and without. Imagination cannot conceive a scene more dreadful than that presented by the devoted city of Antioch on that night of horror. The Crusaders fought with a blind fury, which fanaticism and suffering alike incited. Men, women, and children were indiscriminately slaughtered, till the streets ran with blood. Darkness increased the destruction, for when morning dawned the Crusaders found themselves with their swords at the breasts of their fellow-soldiers, whom they had mistaken for foes. The Turkish commander fled, first to the citadel, and that becoming insecure, to the mountains, whither he was pursued and slain, and his grey head brought back to Antioch as a trophy. At daylight the massacre ceased, and the Crusaders gave themselves up to plunder. They found gold, and jewels, and silks, and velvets in abundance, but of provisions, which were of more importance to them, they found but little of any kind. Corn was excessively scarce, and they discovered to their sorrow that in this respect the besieged had been but little better off than the besiegers.”
