Note 283 — Chapter XIII · THE AFRICAN PROVINCES.
William P. (William Purdie) Dickson translation
In the year 70 the troops of the two Mauretanias amounted together, in addition to militia levied in large numbers, to 5 alae and 19 cohortes (Tacitus, Hist. ii. 58), and so, if we reckon on the average every fourth as a double troop, to about 15,000 men. The regular army of Numidia was weaker rather than stronger.
