When did the Roman Empire fall (your thoughts)?

[ValentinianVictrix]

Sorry but which sources?

250,000+ on on each side sounds about right for total army strength including garrison units, maybe high because many units were below strength, but it's extremely high for field army strength. 50,000 casualties would represent the complete destruction of at least two, probably three, field armies, but it might be the cumulative total for the entire war.

The 250,000 is based on figures given by one source just for the combined troops on both sides at that particular battle. It was probably one of the largest civil war battles ever fought and its repercussions were felt long afterwards, possibly the first identifiable cause for the fall of the western half of the Empire. Sources for the battle are rather scant, Julian discusses it, as does Zosimus, Sozomen, Socrates Scolasticus and Zonarius, Zonarius gives the 50,000+ casualty figure.
