The garrisons of the numerus and cohort forts can be identified by the many inscriptions that have been found. The auxiliary troops often came from outlying provinces. At the Main troops have been identified from Aquitania, Spain, the area around Augsburg, and modern Switzerland, among others. It is assumed that there was a total of about 3,500 men garrisoned at the Limes.
