A regiment of auxiliary infantry soldiers recruited from amongst the Nervii tribe of Belgica province. This unit were probably the first Hadrianic garrison of the fort at Great Chesters on Hadrian's Wall, and were later at Rough Castle on the Antonine Wall in Scotland, where they were evidently responsible for the building of regimental headquarters or principia in the centre of the fort. They are mentioned on three out of five inscriptions on stone, one dated to the beginning of the third century, from Brough by Bainbridge in North Yorkshire, where they are also listed in the Roman administrative document the Notitia Dignitatum of the late-fourth century.
