"Auxilia in Britain?" Topic

I know Legio IX was in Britain during the EIR period, but were they strictly Roman legionaries or were there Auxiliaries from other parts of the empire there as well?

Britain had probably the largest number of auxiliary units as well as the 3 legions.
Even wikipedia lists some of the various units

This link link gives a figure of around 25,500 Auxilia foot & 10,500 Auxilia cavalry in 130CE

Many auxiliaries came from Celtic Gauls whose tribes had been allies of Caesar or were defeated by hin nearly 100 years before the Claudian invasion of Britain. These include the famous Batavia cavalrymen.

Go to archive.org and download a copy of The Auxilia of the Roman Imperial Army by George Leonard Cheesman (1914). That will give you a pretty accurate listing ca. 165AD of the auxiliary units in all but one province, IIRC. He gave a reason for why one was missing but I can't recall which or why right now (and am on my cell phone).

There has of course been considerable archaeological work and scholarship since he published in 1914. However, by my reckoning that has increased the number of known units by only maybe a few dozen at most out of nearly (or over?) 400 that were already known 100+ years ago. For wargaming purposes, Cheesman remains a great source!

Historically the Romans usually had equal numbers of auxilia as legionaries – at the time of the Boudica revolt the Roman Army of Britain for example had four legions – II Augusta, IX Hispania, XIV Gemina and XX Valeria Victrix; there were an equal number of auxilia organized in cohorts; most of the cavalry were auxilia as well as archers (there being a Thracian cohort of archers)

Great! Thanks, gents.

Thanks for the info, Nighthawk! Downloaded… :-)
