Roman Military Campaigns – In Scotland and Northern England

Inchtuthil and the Glen Forts

It is likely that work started on the Inchtuthil fortress no earlier than 85AD, the year after Agricola left Britain. This legionary base was abandoned uncompleted perhaps in the winter of 85/86, certainly by the summer of 86 when the removal from Britain of Legio II Adiutrix for use in Domitian’s Dacian wars forced the Twentieth Legion to be withdrawn from Scotland to maintain the garrison at Chester, recently vacated by the Second.

At the same time as the Inchtuthil legionary base was being built, a number of forts were also constructed at the mouth of each glen leading into the Caledonian highlands, to the south-east of Inchtuthil at: Barochan on the Clyde, Drumquhassle at the SE corner of Loch Lomond, Malling at Menteith, Bochastle at Callander, Dalginross at Comrie and Fendoch at the mouth of the Sma’ Glen, also to the north-east at: Ardoch, Strageath, Bertha, Cargill, Cardean and Stracathro. There may also have been another fort situated in the anomalously large gap between the latter two forts.

Ardoch may have been garrisoned by an auxiliary unit and a legionary cohort, and excavations at Fendoch and Cardean have demonstrated that both forts were evacuated after only a short occupation period. A number of bronze asses of 86AD have been uncovered at a number of military sites in Scotland; Inchtuthil, Camelon, Strageath, Stracathro, Crawford, Newstead, Cramond, Castledykes and Barochan. The finding of these coins, all in almost unworn condition, proves that all of these sites were garrisoned in that year or shortly afterwards. It is almost certain, given the stong garrisons in the glen forts that the Romans intended these camps to act as a springboard into the Caledonian highlands along the lines of the Glens. These plans were halted by the advent of war in Dacia.

“The abandonment of Inchtuthil was almost certainly accompanied by the withdrawal of the garrisons of the glen forts.” (Breeze, p.61)
