Note 324 — THE AUXILIA DURING THE FIRST TWO CENTURIES A.D. (continued 2)
Reading edition
For Haltern see Schuchhardt, Führer durch die Ausgrabungen von Haltern. It is, however, perhaps incorrect to limit the garrison to auxiliaries: for Hofheim cf. Ritterling, Das frührömische Lager bei Hofheim, 1912. It was occupied from about 40 to 60.
