Perhaps the most notable auxiliary regiment in Britain, a unit of bowmen recruited from the Hamian tribesmen of Syria, the only regiment of archers known to have been stationed in Britain. They very likely took part in the Claudian invasion of AD43. They are the known Hadrianic garrison of Carvoran. The unit was moved to Bar Hill on the Antonine Wall during its second occupation period c.AD158, and returned to Carvoran c.163-166, during the reign of Marcus Aurelius. They were stationed at some time in the Housesteads fort on Hadrian's Wall, though their period of occupation at Housesteads is unknown.
