Dein pons continuatus collesque adversi per socias cohortis, post legionum castris occupantur, tanta celeritate et ostentatione virium, ut Parthi omisso paratu invadendae Suriae spem omnem in Armeniam verterent, ubi Paetus imminentium nescius quintam legionem procul in Ponto habebat, reliquas promiscis militum commeatibus infirmaverat, donec adventare Vologesen magno et infenso agmine auditum.
The bridge was finished and the hills ahead were taken over by the allied cohorts, followed by a legionary camp. Their quick movements and impressive display of power convinced the Parthians to abandon their plans to invade Syria and focus their efforts on Armenia. Meanwhile, Paetus was unaware of the approaching danger and had isolated the fifth legion in Pontus. He had also reduced the strength of other legions by giving out furloughs indiscriminately. It was only after news arrived that Vologeses was moving forward with a menacing and imposing army that he realized the gravity of the situation.
