It always struck me at how fortunate the Gauls were in comparison to the rest of the West, everywhere else Roman authority was thrown off and the lands were taken by barbarians and basques, but in Gaul the Empire managed to defend itself against the Franks.
From what I know of the Franks it seemed as if they had more than enough strength to best Syagrius but in OTL they won. What if the armies of Gaul lost in 480?
