was the lack of water; their supply was of poor quality and had to be brought from a distance. The Jews found their underground passages a source of strength. They had these affairs dug from within the city out under the walls to distant points in the country, and going out through them they would attack parties in search of water and harass scattered detachments. Consequently Titus stopped them all up.] [Sidenote:--5--] In the course of these operations many on both sides were wounded and killed. Titus himself was struck on the left shoulder by a stone, and as a result of this accident the arm was always weaker. After a time the Romans managed to scale the outside circle, and, pitching their camps between the two encompassing lines of fortification, assaulted the second wall. Here, however, they found the conditions confronting them to be different. When all the inhabitants had retired behind the second wall, its defence proved an easier matter because the circuit to be guarded was so much less. Titus, accordingly, made anew a proclamation offering them immunity. They, however, even under these circumstances held out. And the captives and deserters from the enemy so far as they could do so unobserved spoiled the Roman water supply and slew many men that they could cut off from the main force, so that Titus refused to receive any of them. Meantime some of the Romans, too, growing disheartened, as often happens in a prolonged siege, and furthermore suspecting that the city was really, even as report declared, impregnable, went over to the other side. The Jews although they were short of food treated them kindly, in order to be able to exhibit deserters to their own ranks.
