The Roman History · Amm. 30.2.4

After this, the matter becoming a source of greater anxiety, the emperor, who was more skilful in choosing between different plans than in devising them himself, thinking that it would be beneficial to the state in general, ordered Victor, the commander of the cavalry, and Urbicius, the Duke of Mesopotamia, to march with all speed to Persia, bearing a positive and plain answer to the proposals of Sapor: namely, that he, who boasted of being a just man, and one contented with his own, was acting wickedly in coveting Armenia, after a promise had been made to its inhabitants, that they should be allowed to live according to their own laws. And unless the soldiers who had been left as auxiliaries to Sauromaces returned without hindrance at the beginning of the ensuing year, as had been agreed, he would compel Sapor by force to perform what he might at present do with a good grace.
