Note 216 — THE AUXILIA DURING THE FIRST TWO CENTURIES A.D.
Reading edition
It seems that all the eight Batavian cohorts which supported Civilis were dismissed, and that the Cohorts I and II Batavorum, which we meet on second-century inscriptions, were new creations. The Alae Petriana and Sebosiana and two cohorts of Tungrians, which had formed part of the Rhine army in 69, appear later in Britain. But they had left the Rhine to take part in the civil war in Italy, and were not guilty of complicity in the mutiny.
