The lance was therefore sought for in form, and though at first it could not be discovered, because it was not there, it very naturally happened that no sooner did the clerk who had been favoured with the vision descend into the pit,[381] than the iron head was perceived, and brought up to the wonder and edification of the people. The matter being now decided, the hearts of the multitude were all enthusiasm, a great many more almost sacrilegious visions were seen, fasting and prayer, and the ceremonies of the church were used to excite and increase the popular ardour; and, in the end, Peter the Hermit was sent out to the camp of Kerboga,[382] not to offer terms of capitulation, but rather to threaten vengeance, and to bid the Turks depart. The reply of the emir was as contemptuous as might have been expected, and Peter returned with a message that would have somewhat quelled the daring of the crusaders if it had been repeated. This, however, was prevented by Godfrey, and every preparation made for a battle. The citadel,[383] I have before said, had remained in the hands of the Turks, who had fled thither on the taking of Antioch. Its commanding situation enabled the garrison to see whatever passed in the town; and the governor being strictly enjoined to give due notice to the army of Kerboga of all the Christian movements, on the morning of the 28th of June, A. D. 1098, a black flag,[384] hoisted on the highest tower of that fortress, announced to the besiegers that the Latins were about to march out and attack them.
