After a while the Roman left was in difficulties.

Here the Cadiseni (Cadusians ?) under Pituazes routed their opponents, and were pursuing them hastily when the Massagetic horse, commanded by Sunicas and Aigan, and three hundred Heruli under a chief called Pharas, charged them on their right flank, and at once threw them into disorder.

Three thousand fell, and the rest were driven back upon their main body, which, still continued to fight bravely.

The Romans did not push their advantage, but were satisfied to reoccupy the ground from which they had been driven.
Scarcely was the battle re-established in this quarter when the Romans found themselves in still greater difficulties upon their right.
Here Perozes had determined to deliver his main attack.

The corps of Immortals, which he had kept in reserve, and such troops as he could spare from his centre, were secretly massed upon his own left, and charged the Roman right with such fury that it was broken and began a hasty retreat.
