Not only did it arrive too late to save Amida, but it in no way interfered with the after-movements of Kobad, who, leaving a small garrison to maintain his new conquest, carried off the whole of his rich booty to his city of Nisibis, and placed the bulk of his troops in a good position upon his own frontier.

When Areobindus, at the head of the first division, reached Amida and heard that the Persians had fallen back, he declined the comparatively inglorious work of a siege, and pressed forward, anxious to carry the war into Persian territory.

He seems actually to have crossed the border and invaded the district of Arzanene, when news reached him that Kobad was marching upon him with all his troops, whereupon he instantly fled, and threw himself into Constantia, leaving his camp and stores to be taken by the enemy.

Meanwhile another division of the Roman army, under Patrilcius and Hypatius, had followed in the steps of Areobindus, and meeting with the advance-guard of Kobad, which consisted of eight hundred Ephthalites, had destroyed it almost to a man.
Ignorant, however, of the near presence of the main Persian army, this body of troops allowed itself soon afterwards to be surprised on the banks of a stream, while some of the men were bathing and others were taking their breakfast, and was completely cut to pieces by Kobad, scarcely any but the generals escaping.
Thus far success had been wholly on the side of the Persians; and if circumstances had permitted Kobad to remain at the seat of war and continue to direct the operations of his troops in person, there is every to reason to believe that he would have gained still greater advantages.

The Roman generals were incompetent; they were at variance among themselves; and they were unable to control the troops under their command.
