Eunomius not merely animated the defenders, but took part personally in the defence, and even on one occasion discharged a stone from a balista with his own hand, and killed a prince who had not confined himself to his military duties, but had insulted the faith of the besieged.

The death of this officer is said to have induced Varahran to retire, and not further molest Theodosiopolis.
While the fortified towns on either side thus maintained themselves against the attacks made on them, Theodosius, we are told, gave an independent command to the patrician Procopius, and sent him at the head of a body of troops to oppose Varahran.

The armies met, and were on the point of engaging when the Persian monarch made a proposition to decide the war, not by a general battle, but by a single combat.

Procopius assented; and a warrior was selected on either side, the Persians choosing for their champion a certain Ardazanes, and the Romans "Areobindus the Goth," count of the "Foederati." In the conflict which followed the Persian charged his adversary with his spear, but the nimble Goth avoided the thrust by leaning to one side, after which he entangled Ardazanes in a net, and then despatched him with his sword.
The result was accepted by Varahran as decisive of the war, and he desisted, from any further hostilities.

Areobindus received the thanks of the emperor for his victory, and twelve years later was rewarded with the consulship.
But meanwhile, in other portions of the wide field over which the war was raging, Rome had obtained additional successes.
