His troops were "limitanei" or frontier guards and not the "comitatenses" or field army commanded by the Comes Britanniarum. Fourteen units in north Britain are listed in the "Notitia" as being under his command, stationed in either modern Yorkshire, Cumbria or Northumberland. Archaeological evidence indicates there were other posts occupied at the time which are not listed. His forces included three cavalry "vexillationes" with the rest being infantry. They were newly raised units rather than being third century creations. In addition to these fort garrisons, the "dux" commanded the troops at Hadrian's Wall: the "Notitia" lists their stations from east to west, as well as additional forts on the Cumbrian coast. These troops appear to have been third century regiments, although the reliability of the "Notitia" makes it difficult to infer any solid information from it.
