unable to get out, in spite of the entreaties of their tribunes, they became furious as wild beasts. But on subsequent occasions their services became conspicuous, as we shall show.
In a remote part of the walls on the southern side, which looks down on the Tigris, there was a high tower, below which yawned an abrupt precipice, which it was impossible to look over without giddiness. From this by a hollow subterranean passage along the foot of the mountain some steps were cut with great skill, which led up to the level of the city, by which water was secretly obtained from the river, as we have seen to be the case in all the fortresses in that district which are situated on any river.
This passage was dark, and because of the precipitous character of the rock was neglected by the besiegers, till, under the guidance of a deserter who went over to them, seventy Persian archers of the royal battalion, men of eminent skill and courage, being protected by the remoteness of the spot which prevented their being heard, climbed up by the steps one by one at midnight, and reached the third story of the tower. There they concealed themselves till daybreak, when they held out a scarlet cloak as a signal for commencing an assault, when they saw that the city was entirely surrounded by the multitude of their comrades; and then they emptied their quivers and threw them down at their feet, and with loud cries shot their arrows among the citizens with prodigious skill.
And presently the whole of the mighty host of the enemy assaulted the city with more ferocity than ever. And while we stood hesitating and perplexed to know which danger to oppose first, whether to make head against the foe above us, or against the multitude who were scaling the battlements with ladders, our force was divided; and five of the lighter balistæ were brought round and placed so as to attack our tower. They shot out heavy wooden javelins with great rapidity, sometimes transfixing two of our men at one blow, so that many of them fell to the ground severely wounded, and some jumped down in haste from fear of the creaking engines, and being terribly lacerated by the fall, died.
But by measures promptly taken, the walls were again secured on that side, and the engines replaced in their former situation.
And since the crime of desertion had increased the labours of our soldiers, they, full of indignation, moved along the battlements as if on level ground, hurling missiles of all kinds, and exerting themselves so strenuously that the Virtæ, who were attacking on the south side, were repulsed covered by wounds, and retired in consternation to their tents, having to lament the fall of many of their number.

§ 1. Thus fortune showed us a ray of safety, granting us one day in which we suffered but little, while the enemy sustained a heavy loss; the remainder of the day was given to rest in order to recruit our strength; and at the dawn of the next morning we saw from the citadel an innumerable multitude, which, after the capture of the fort called Ziata, was being led to the enemy's camp. For a promiscuous multitude had taken refuge in Ziata on account of its size and strength; it being a place ten furlongs in circumference.
In those days many other fortresses also were stormed and burnt, and many thousands of men and women carried off from them into slavery; among whom were many men and women, enfeebled by age, who, fainting from different causes, broke down under the length of the journey, gave up all desire of life, and were hamstrung and left behind.
The Gallic soldiers beholding these wretched crowds, demanded by a natural but unseasonable impulse to be led against the forces of the enemy, threatening their tribunes and principal centurions with death if they refused them leave.
