Note 63 — Chapter IV

The strength of the auxilia of the upper army may be fixed for the epoch of Domitian and Trajan with tolerable certainty at about 10,000 men. A document of the year 90 enumerates four alae and fourteen cohortes of this army; to these is to be added at least one cohort (I Germanorum), which, it can be shown, did garrison–duty there as well in the year 82 as in the year 116; whether two alae which were there in the year 82, and at least three cohorts which were there in 116, and which are absent from the list of the year 90, were doing garrison work there in 90 or not, is doubtful, but most of them probably were away from the province before 90 or only came into it after 90. Of those nineteen auxilia one was certainly (coh. I Damascenorum), another perhaps (ala I Flavia gemina), a double division. At the minimum, therefore, the figure indicated above results as the normal state of the auxilia of this army, and it cannot have been materially exceeded. But the auxilia of lower Germany, whose garrisons were less extended, may well have been smaller in number.
