When news of this defeat reached Pacorus, he resolved to retreat, and withdrew his troops across the Euphrates.

This movement he appears to have executed without being molested by Ventidius, who thus recovered Syria to the Romans towards the close of B.C.39, or early in B.C.

38.
But Pacorus was far from intending to relinquish the contest.

He had made himself popular among the Syrians by his mild and just administration, and knew that they preferred his government to that of the Romans.

He had many allies among the petty princes and dynasts, who occupied a semi-independent position on the borders of the Parthian and Roman empires.
