Roman soldiers and Parthian Travelers

[Robert Vermaat]

I need to prove that some Roman soldiers were very angry about being defeated by the Parthian army.  I need to prove that some Roman soldiers were corrupt and willing to do things in secret that they wouldn't do publicly.  If I could prove both things, I could give reasonable proof that some Roman soldiers punished weary Parthian travelers because of the wars they lost.

Hi 'speedlearner',

To be able to pove anything like that you'll need a source that would tell such a story. So far I am unaware of anything like that, although I could think of scenarios in which Parthian traders would hesitate to visit Roman territory after a Roman defeat. Of course, the reverse could also be logical.
