Late Roman Army during the 5th century

[Robert Vermaat]

Goldsworthy wrote that, after a string of victories, the Huns were severely defeated at Arelate in 439. I wonder: considering their importance to Aetius, could this setback have emboldened the Suevi in Spain, and Geiseric, to seize Roman territory, notably Carthage?

Are you sure of the place and the date? I don't know of a battle of Arles against the Huns in 439? Attila only becomes king in 445 and before that, the Huns are Roman allies? It was the Visigoths who were active around Arles around that time I think?

EDIT: ah, you mean the battles of Narbo Martius and Tolosa against the Visigoths. Litorius being captured and killed and all that. I doubt that this meant the end of the Huns as allies of the Romans. There were plenty more where these came from. I rather think that Attila put and end to that alliance a few years later.
