However, the Huns looted and pillaged much of Gaul and crippled the military capacity of the Romans and Visigoths. Attila died only two years later, in After the Battle of Nedao in , the coalition of the Huns and the incorporated Germanic vassals gradually disintegrated.
By AD, the Romans had restored their authority in much of the province of Gaul , although control over all of the provinces beyond Italy was continuing to diminish.
