Where was the Roman Army in AD408?

[Flavivs Aetivs]

Eh... maybe... Modern interpretation of foederati suggests that by the 420's they were more similar to what they were under Anastasius-Maurice than what they were in the 4th century. I argue in my book that the "settled" peoples of Gaul (they weren't settled actually, not until like the 450's) were essentially operating as and being paid as additional field armies. Germanics in Roman units were basically Roman soldiers and indistinguishable.
