Benito indeed counts as a person with extraordinary decisiveness, especially when he returned to the Roman Eastern Province and joined with Dirina, bringing along an entire staff group, or rather, a civil official group. Benito no longer engaged in any probing but directly abandoned vast territories, intercepting step by step, continually harassing, using space to buy time.
Retreating from Dura-Europus all the way to Antioch, there were basically no large-scale engagements with the Parthians, mostly using harassing tactics to delay the Parthian advance. Yet, the Parthians, being numerous and powerful, pressed forward relentlessly, making it difficult for Benito to hold them up despite his best efforts.
Even though Roman citizens were recruited by Dirina, they weren't trained or reorganized, thus despite experience, their combat power was hard to meet standards. Benito, being wise, naturally avoided confronting the Parthians head-on.
