After this, having risen greatly in favour with the Empress, she sent Theodosius to Ephesus, and herself, foreseeing no trouble, set out for the East.
Belisarius had just captured the fortress of Sisauranum, when he was told of his wife’s arrival; whereupon he immediately ordered his army to turn back, disregarding the interests of the Empire for the sake of his private feelings. Certain matters had indeed happened, as I have already set forth, which made a retreat advisable, but his wife’s presence hastened it considerably. But, as I said at the beginning, I did not then think it safe to describe the real motives of men’s actions.
Belisarius was reproached by all the Romans for having sacrificed the interests of his country to his domestic affairs. The reason was that, in his first transport of passion against his wife, he could not bring himself to go far away from Roman territory; for he felt that the nearer he was, the easier it would be for him to take vengeance upon Theodosius, as soon as he heard of the arrival of Antonina.
He therefore ordered Arethas and his people to cross the river Tigris, and they returned home, without having performed anything worthy of record, while he himself took care not to retire more than an hour’s journey from the Roman frontier. The fortress of Sisauranum, indeed, for an active man, is not more than a day’s journey from the frontier by way of Nisibis, and only half that distance if one goes by another route. But had he chosen to cross the river Tigris at first with all his host, I have no doubt that he would have been able to carry off all the riches of Assyria, and extend his conquests as far as the city of Ctesiphon, without meeting with any opposition. He might even have secured the release of the Antiochians, and all the other Romans who were there in captivity, before returning home.
Furthermore, he was chiefly to blame for the extreme ease with which Chosroes led his army home from Colchis. I will now relate how this came to pass. When Chosroes, the son of Cabades, invaded Colchis, with the result which I have recounted elsewhere, and took Petra, the Medes nevertheless sustained severe losses, both in battle and owing to the difficulties of the country; for, as I have said already, Lazica is a country almost inaccessible, owing to its rocks and precipices. They had at the same time been attacked by pestilence, which carried off the greater part of the troops, and many died from want of food and necessaries. It was at this crisis of affairs that certain men from Persia came into that country, bringing the news that Belisarius had beaten Nabedes in a battle near the city of Nisibis, and was pressing forward; that he had taken the fortress of Sisauranum, and had made prisoners of Bleschames and eight hundred Persian lancers; that another corps of Romans under Arethas, the chief of the Saracens, had been detached to cross the Tigris, and ravage the land to the east of that river, which up to that time had remained free from invasion.
