 Besides his activity in ameliorating the hard pecuniary situation of the province, Cicero was also creditably active in the military sphere.Early in his governorship he received information that prince Pacorus, son of Orodes II the king of the Parthians, had crossed the Euphrates, and was ravaging the Syrian countryside and had even besieged Cassius (the interim Roman commander in Syria) in Antioch.Cicero eventually marched with two understrength legions and a large contingent of auxiliary cavalry to Cassius's relief.
