Vespasian, therefore, in order to try how he might overcome the natural strength of the place, as well as the bold defence of the Jews, made a resolution to prosecute the siege with vigour. To that end he called the commanders that were under him to a council of war, and consulted with them which way the assault might be managed to the best advantage; and when the resolution was there taken to raise a bank against that part of the wall which was practicable, he sent his whole army abroad to get the materials together. So when they had cut down all the trees on the mountains that adjoined to the city, and had gotten together a vast heap of stones, besides the wood they had cut down, some of them brought hurdles, in order to avoid the effects of the darts that were shot from above them. These hurdles they spread over their banks, under cover whereof they formed their bank, and so were little or nothing hurt by the darts that were thrown upon them from the wall, while others pulled the neighbouring hillocks to pieces, and perpetually brought earth to them; so that while they were busy three sorts of ways, nobody was idle. However, the Jews cast great stones from the walls upon the hurdles which protected the men, with all sorts of darts also; and the noise of what could not reach them was yet so terrible, that it was some impediment to the workmen. Vespasian then set the engines for throwing stones and darts round about the city; the number of the engines was in all a hundred and sixty; and bade them fall to work and dislodge those that were upon the wall. At the same time such engines as were intended for that purpose, threw at once lances upon them with great noise, and stones of the weight of a talent were thrown by the engines that were prepared for that purpose, together with fire, and a vast multitude of arrows, which made the wall so dangerous, that the Jews durst not only not to come upon it, but durst not come to those parts within the walls which were reached by the engines; for the multitude of the Arabian archers, as well also as all those that threw darts and slung stones, fell to work at the same time with the engines. Yet did not the others lie still when they could not throw at the Romans from a higher place; for they then made sallies out of the city like private robbers, by parties, and pulled away the hurdles that covered the workmen, and killed them when they were thus naked; and when those workmen gave way, these cast away the earth that composed the bank, and burnt the wooden parts of it, together with the hurdles, till at length Vespasian perceived that the intervals there were between the works were of disadvantage to him; for those spaces of ground afforded the Jews a place for assaulting the Romans. So he united the hurdles, and at the same time joined one part of the army to the other, which prevented the private excursions of the Jews.
