At this time Belisarius had arrived in Mesopotamia and was gathering his army from every quarter, and he also kept sending men into the land of Persia to act as spies. And wishing himself to encounter the enemy there, if they should again make an incursion into the land of the Romans, he was organizing on the spot and equipping the soldiers, who were for the most part without either arms or armour, and in terror of the name of the Persians. Now the spies returned and declared that for the present there would be no invasion of the enemy; for Chosroes was occupied elsewhere with a war against the Huns. And Belisarius, upon learning this, wished to invade the land of the enemy immediately with his whole army. Arethas also came to him with a large force of Saracens, and besides the emperor wrote a letter instructing him to invade the enemy's country with all speed. He therefore called together all the officers in Daras and spoke as follows: "I know that all of you, my fellow officers, are experienced in many wars, and I have brought you together at the present time, not in order to stir up your minds against the enemy by addressing to you any reminder or exhortation (for I think that you need no speech that prompts to daring), but in order that we may deliberate together among ourselves, and choose rather the course which may seem fairest and best for the cause of the emperor. For war is wont to succeed by reason of careful planning more than by anything else. Now it is necessary that those who gather for deliberation should make their minds entirely free from modesty and from fear. For fear, by paralyzing those who have fallen into it, does not allow the reason to choose the nobler part, and modesty obscures what has been seen to be the better course and leads investigation the opposite way. If, therefore, it seems to you that any purpose has been formed either by our mighty emperor or by me concerning the present situation, let no thought of this enter your minds. For, as for him, he is altogether ignorant of what is being done, and is therefore unable to adapt his moves to opportune moments; there is therefore no fear but that in going contrary to him we shall do that which will be of advantage to his cause. And as for me, since I am human, and have come here from the West after a long interval, it is impossible that some of the necessary things should not escape me. So it behoves you, without any too modest regard for my opinion, to say outright whatever is going to be of advantage for ourselves and for the emperor. Now in the beginning, fellow officers, we came here in order to prevent the enemy from making any invasion into our land, but at the present time, since things have gone better for us than we had hoped, it is possible for us to make his land the subject of our deliberation. And now that you have been gathered together for this purpose, it is fair, I think, that you should tell without any concealment what seems to each one best and most advantageous." Thus spoke Belisarius.
And Peter and Bouzes urged him to lead the army without any hesitation against the enemy's country. And their opinion was followed immediately by the whole council. Rhecithancus, however, and Theoctistus, the commanders of the troops in Lebanon, said that, while they too had the same wish as the others concerning the invasion, they feared that if they abandoned the country of Phoenicia and Syria, Alamoundaras would plunder it at his leisure, and that the emperor would be angry with them because they had not guarded and kept unplundered the territory under their command, and for this reason they were quite unwilling to join the rest of the army in the invasion. But Belisarius said that the opinion of these two men was not in the least degree true; for it was the season of the vernal equinox, and at this season the Saracens always dedicated about two months to their god, and during this time never undertook any inroad into the land of others. Agreeing, therefore, to release both of them with their followers within sixty days, he commanded them also to follow with the rest of the army. So Belisarius was making his preparation for the invasion with great zeal.

But Chosroes and the Median army, after crossing Iberia, reached the territory of Lazica under the leadership of the envoys; there with no one to withstand them they began to cut down the trees which grow thickly over that very mountainous region, rising to a great height, and spreading out their branches remarkably, so that they made the country absolutely impassable for the army; and these they threw into the rough places, and thus rendered the road altogether easy. And when they arrived in the centre of Colchis (the place where the tales of the poets say that the adventure of Medea and Jason took place), Goubazes, the king of the Lazi, came and did obeisance to Chosroes, the son of Cabades, as Lord, putting himself together with his palace and all Lazica into his hand.
Now there is a coast city named Petra in Colchis, on the sea which is called the Euxine, which in former times had been a place of no importance, but which the Emperor Justinian had rendered strong and otherwise conspicuous by means of the circuit-wall and other buildings which he erected. When Chosroes ascertained that the Roman army was in that place with John, he sent an army and a general, Aniabedes, against them in order to capture the place at the first onset. But John, upon learning of their approach, gave orders that no one should go outside the fortifications nor allow himself to be seen from the parapet by the enemy, and he armed the whole army and stationed them in the vicinity of the gates, commanding them to keep silence and not allow the least sound of any kind to escape from them. So the Persians came close to the fortifications, and since nothing of the enemy was either seen or heard by them they thought that the Romans had abandoned the city and left it destitute of men. For this reason they closed in still more around the fortifications, so as to set up ladders immediately, since no one was defending the wall. And neither seeing nor hearing anything of the enemy, they sent to Chosroes and explained the situation. And he sent the greater part of the army, commanding them to make an attempt upon the fortifications from all sides, and he directed one of the officers to make use of the engine known as a ram around the gate, while he himself, seated on the hill which lies very close to the city, became a spectator of the operations. And straightway the Romans opened the gates all of a sudden, and unexpectedly fell upon and slew great numbers of the enemy, and especially those stationed about the ram; the rest with difficulty made their escape together with the general and were saved. And Chosroes, filled with rage, impaled Aniabedes, since he had been outgeneralled by John, a tradesman and an altogether unwarlike man. But some say that not Aniabedes, but the officer commanding the men who were working the ram was impaled. And he himself broke camp with the whole army, and coming close to the fortifications of Petra, made camp and began a siege. On the following day he went completely around the fortifications, and since he suspected that they could not support a very strong attack, he decided to storm the wall. And bringing up the whole army there, he opened the action, commanding all to shoot with their bows against the parapet. The Romans, meanwhile, in defending themselves, made use of their engines of war and all their bows. At first, then, the Persians did the Romans little harm, although they were shooting their arrows thick and fast, while at the same time they suffered severely at the hands of the Romans, since they were being shot at from an elevation. But later on (since it was fated that Petra be captured by Chosroes), John by some chance was shot in the neck and died, and as a result of this the other Romans ceased to care for anything. Then indeed the barbarians withdrew to their camp; for it was already growing dark; but on the following day they planned to assail the fortifications by an excavation, as follows.
The city of Petra is on one side inaccessible on account of the sea, and on the other on account of the sheer cliffs which rise there on every hand; indeed it is from this circumstance that the city has received the name it bears. And it has only one approach on the level ground, and that not very broad; for exceedingly high cliffs overhang it on either side. At that point those who formerly built the city provided that that portion of the wall should not be open to attack by making long walls which ran along beside either cliff and guarded the approach for a great distance. And they built two towers, one in each of these walls, not following the customary plan, but as follows. They refused to allow the space in the middle of the structure to be empty, but constructed the entire towers from the ground up to a great height of very large stones which fitted together, in order that they might never be shaken down by a ram or any other engine. Such, then, are the fortifications of Petra. But the Persians secretly made a tunnel into the earth and got under one of the two towers, and from there carried out many of the stones and in their place put wood, which a little later they burned. And the flame, rising little by little, weakened the stones, and all of a sudden shook the whole tower violently and straightway brought it down to the ground. And the Romans who were on the tower perceived what was being done in sufficient time so that they did not fall with it to the ground, but they fled and got inside the city wall. And now it was possible for the enemy to storm the wall from the level, and thus with no trouble to take the city by force. The Romans, therefore, in terror, opened negotiations with the barbarians, and receiving from Chosroes pledges concerning their lives and their property, they surrendered to him both themselves and the city. Thus Chosroes captured Petra. 541 A.D. And finding the treasures of John, which were extremely rich, he took them himself, but besides this neither he himself nor anyone else of the Persians touched anything, and the Romans, retaining their own possessions, mingled with the Median army.

Meantime Belisarius and the Roman army, having learned nothing of what was being done there, were going in excellent order from the city of Daras toward Nisibis. And when they had reached the middle of their journey, Belisarius led the army to the right where there were abundant springs of water and level ground sufficient for all to camp upon. And there he gave orders to make a camp at about forty-two stades from the city of Nisibis. But all the others marvelled greatly that he did not wish to camp close to the fortifications, and some were quite unwilling to follow him. Belisarius therefore addressed those of the officers who were about him thus: "It was not my wish to disclose to all what I am thinking. For talk carried about through a camp cannot keep secrets, for it advances little by little until it is carried out even to the enemy. But seeing that the majority of you are allowing yourselves to act in a most disorderly manner, and that each one wishes to be himself supreme commander in the war, I shall now say among you things about which one ought to keep silence, mentioning, however, this first, that when many in an army follow independent judgments it is impossible that anything needful be done. Now I think that Chosroes, in going against other barbarians, has by no means left his own land without sufficient protection, and in particular this city which is of the first rank and is set as a defence to his whole land. In this city I know well that he has stationed soldiers in such number and of such valour as to be sufficient to stand in the way of our assaults. And the proof of this you have near at hand. For he put in command of these men the general Nabedes, who, after Chosroes himself at least, seems to be first among the Persians in glory and in every other sort of honour. This man, I believe, will both make trial of our strength and will permit of our passing by on no other condition than that he be defeated by us in battle. If, therefore, the conflict should be close by the city, the struggle will not be even for us and the Persians. For they, coming out from their stronghold against us, in case of success, should it so happen, will feel unlimited confidence in assailing us, and in case of defeat they will easily escape from our attack. For we shall only be able to pursue them a short distance, and from this no harm will come to the city, which you surely see cannot be captured by storming the wall when soldiers are defending it. But if the enemy engage with us here and we conquer them, I have great hopes, fellow officers, of capturing the city. For while our antagonists are fleeing a long way, we shall either mingle with them and rush inside the gates with them, as is probable, or we shall anticipate them and compel them to turn and escape to some other place, and thus render Nisibis without its defenders easy of capture for us."
When Belisarius had said this, all the others except Peter were convinced, and they made camp and remained with him. He, however, associating with himself John, who commanded the troops in Mesopotamia and had no small part of the army, came up to a position not far removed from the fortifications, about ten stades away, and remained quietly there. But Belisarius marshalled the men who were with him as if for combat, and sent word to Peter and his men also to hold themselves in array for battle, until he himself should give the signal; and he said that he knew well that the barbarians would attack them about midday, remembering, as they surely would, that while they themselves are accustomed to partake of food in the late afternoon, the Romans do so about midday. So Belisarius gave this warning; but Peter and his men disregarded his commands, and about midday, being distressed by the sun (for the place is exceedingly dry and hot), they stacked their arms, and with never a thought of the enemy began to go about in disorderly fashion and eat gourds which grew there. And when this was observed by Nabedes, he led the Persian army running at full speed against them. And the Romans, since they did not fail to observe that the Persians were coming out of the fortifications (for they were seen clearly because moving over a level plain), sent to Belisarius urging him to support them, and they themselves snatched up their arms, and in disorder and confusion confronted their foe. But Belisarius and his men, even before the messenger had reached them, discovered by the dust the attack of the Persians, and went to the rescue on the run. And when the Persians came up, the Romans did not withstand their onset, but were routed without any difficulty, and the Persians, following close upon them, killed fifty men, and seized and kept the standard of Peter. And they would have slain them all in this pursuit, for the Romans had no thought of resistance, if Belisarius and the army with him had not come upon them and prevented it. For as the Goths, first of all, came upon them with long spears in close array, the Persians did not await their attack but beat a hasty retreat. And the Romans together with the Goths followed them up and slew a hundred and fifty men. For the pursuit was only of short duration, and the others quickly got inside the fortifications. Then indeed all the Romans withdrew to the camp of Belisarius, and the Persians on the following day set up on a tower instead of a trophy the standard of Peter, and hanging sausages from it they taunted the enemy with laughter; however, they no longer dared to come out against them, but they guarded the city securely.
