[351] To that offer of Titus they made this reply: That they could not accept of it, because they had sworn never to do so; but they desired they might have leave to go through the wall that had been made about them, with their wives and children; for that they would go into the desert, and leave the city to him. At this Titus had great indignation, that when they were in the case of men already taken captives, they should pretend to make their own terms with him, as if they had been conquerors. So he ordered this proclamation to be made to them, That they should no more come out to him as deserters, nor hope for any further security; for that he would henceforth spare nobody, but fight them with his whole army; and that they must save themselves as well as they could; for that he would from henceforth treat them according to the laws of war. So he gave orders to the soldiers both to burn and to plunder the city; who did nothing indeed that day; but on the next day they set fire to the repository of the archives, to Acra, to the council-house, and to the place called Ophlas; at which time the fire proceeded as far as the palace of queen Helena, which was in the middle of Acra; the lanes also were burnt down, as were also those houses that were full of the dead bodies of such as were destroyed by famine.
