And the Goths not long after this wished to strike a blow at the fortifications of Rome. And first they sent some men by night into one of the aqueducts, from which they themselves had taken out the water at the beginning of this war.[165] And with lamps and torches in their hands they explored the entrance into the city by this way. Now it happened that not far from the small Pincian Gate an arch of this aqueduct[166] had a sort of crevice in it, and one of the guards saw the light through this and told his companions; but they said that he had seen a wolf passing by his post. For at that point it so happened that the structure of the aqueduct did not rise high above the ground, and they thought that the guard had imagined the wolf's eyes to be fire. So those barbarians who explored the aqueduct, upon reaching the middle of the city, where there was an upward passage built in olden times leading to the palace itself, came upon some masonry there which allowed them neither to advance beyond that point nor to use the ascent at all. This masonry had been put in by Belisarius as an act of precaution at the beginning of this siege, as has been set forth by me in the preceding narrative.[167] So they decided first to remove one small stone from the wall and then to go back immediately, and when they returned to Vittigis, they displayed the stone and reported the whole situation. And while he was considering his scheme with the best of the Goths, the Romans who were on guard at the Pincian Gate recalled among themselves on the following day the suspicion of the wolf. But when the story was passed around and came to Belisarius, the general did not treat the matter carelessly, but immediately sent some of the notable men in the army, together with the guardsman Diogenes, down into the aqueduct and bade them investigate everything with all speed. And they found all along the aqueduct the lamps of the enemy and the ashes which had dropped from their torches, and after observing the masonry where the stone had been taken out by the Goths, they reported to Belisarius. For this reason he personally kept the aqueduct under close guard; and the Goths, perceiving it, desisted from this attempt.
But later on the barbarians went so far as to plan an open attack against the fortifications. So they waited for the time of lunch, and bringing up ladders and fire, when their enemy were least expecting them, made an assault upon the small Pincian Gate, emboldened by the hope of capturing the city by a sudden attack, since not many soldiers had been left there. But it happened that Ildiger and his men were keeping guard at that time; for all were assigned by turns to guard-duty. So when he saw the enemy advancing in disorder, he went out against them before they were yet drawn up in line of battle and while they were advancing in great disarray, and routing those who were opposite him without any trouble he slew many. And a great outcry and commotion arose throughout the city, as was to be expected, and the Romans gathered as quickly as possible to all parts of the fortifications; whereupon the barbarians after a short time retired to their camp baffled.
But Vittigis resorted again to a plot against the wall. Now there was a certain part of it that was especially vulnerable, where the bank of the Tiber is, because at this place the Romans of old, confident in the protection afforded by the stream, had built the wall carelessly, making it low and altogether without towers; Vittigis therefore hoped to capture the city rather easily from that quarter. For indeed there was not even any garrison there of any consequence, as it happened. He therefore bribed with money two Romans who lived near the church of Peter the Apostle to pass along by the guards there at about nightfall carrying a skin full of wine, and in some way or other, by making a show of friendship, to give it to them, and then to sit drinking with them well on into the night; and they were to throw into the cup of each guard a sleep-producing drug which Vittigis had given them. And he stealthily got ready some skiffs, which he kept at the other bank; as soon as the guards should be overcome by sleep, some of the barbarians, acting in concert, were to cross the river in these, taking ladders with them, and make the assault on the wall. And he made ready the entire army with the intention of capturing the whole city by storm. After these arrangements were all complete, one of the two men who had been prepared by Vittigis for this service (for it was not fated that Rome should be captured by this army of the Goths) came of his own accord to Belisarius and revealed everything, and told who the other man was. So this man under torture brought to light all that he was about to do and displayed the drug which Vittigis had given him. And Belisarius first mutilated his nose and ears and then sent him riding on an ass into the enemy's camp. And when the barbarians saw him, they realised that God would not allow their purposes to have free course, and that therefore the city could never be captured by them.
