When these and other less important and trifling matters had been arranged as Constantius thought would be to his advantage under the circumstances, he was informed by messages and letters of his generals that the Persian forces had united with their haughty king at their head, and were already drawing near to the banks of the Tigris, but that where they were intending to break through was uncertain.
Aroused by this news, Constantius left his winter quarters as speedily as pos- sible, in order to act from nearer at hand and so be able to anticipate the coming attempts. He gathered from all sides cavalry and the flower of his infantry, on which he relied, and crossing the Euphrates by Capersana[*](Cf. xviii. 8, 1.) on a bridge of boats, proceeded to Edessa, a city strongly fortified and well supplied with provisions; there he waited for a
