This legion was originally raised in the Narbonne area of France and was granted the honorific title “pia fedilis” (“pious and faithful”) by the emperor Vespasian. It was posted to Britain in 70AD and was based in Chester. It was one of 4 legions that invaded Scotland with Agricola in 71 AD. The legion was moved to the Danube.
