“…The size of the force based at each of these three forts was rather larger than that at a normal Roman auxiliary fort, but nevertheless is comparable to the size of establishments at larger forts such as Newstead. The garrison of one of the smaller posts, Ruthven Barracks, 120 men (Stell 1983), was similar to that of a Roman fortlet, while that of another, Corgarff Castle, was 45 (Maclvor 1986), perhaps the garrison of a smaller fortlet. Furthermore, it may be considered that there is some similarity between the relative nature of the forces on the two occasions, a better trained and disciplined standing army facing native tribes or clans.…”
