Ch. VIII. The City of Acre, from its strong position, and its being defended by the choicest men of the Turks, appeared difficult to be taken by assault. The French had hitherto spent their labour in vain in constructing machines and engines for breaking down the walls, with the greatest care; for whatever they erected, at a great expense, the Turks destroyed with Greek fire or some devouring conflagration. Amongst other machines and engines which the King of France had erected for breaking down the walls, he had prepared one with great labour, to be used for scaling it, which they called a "cat," because like a cat it crept up and adhered to the wall. He had also another, made of strong hurdle twigs, put together most compactly, which they used to call a "cercleia," and under its covering of hides the King of France used to sit, and employ himself in throwing darts from a sling; he would thus watch the approach of the Turks, above on the walls, by the battlements, and then hit them unawares. But it happened one day that the French were eagerly pressing forward to apply their cat to the walls, when behold! the Turks let down upon it a heap of the driest wood, and threw upon it a quantity of Greek fire, as well as upon the hurdle they had constructed with such toil, and then aimed a petraria in that direction, and all having forthwith caught fire, they broke them in pieces by the blows from their petraria. Upon this the King of France was enraged beyond measure, and began to curse all those who were under his command; and rated them shamefully for not exacting condign vengeance of the Saracens, who had done them such injuries. In the heat of his passion, and when the day was drawing in, he published an edict, by voice of herald, that an assault should be made upon the city on the morrow.
