Auxiliary Cohorts and their titles

[D B Campbell]

Did they also not use barges or boats along the Euphrates during Trajans campaign?

That, too, is an interesting thought: presumably marines from the Syrian fleet were drafted in to pilot the boats during the various Parthian wars.

But the "new" Arabian diploma dates to AD 142 (Antoninus Pius), and Jona's point is (I think) that Arabia is one enormous desert -- not the kind of place that marines would immediately feel at home! :wink:

(But we are perhaps stealing Jasper's thunder -- should we save the discussion for AW 4.4?)
