Although initially staying his hand (probably through the intervention of the new Praetorian Prefect of the East Caesarius), Gainas eventually withdrew with his Gothic mercenaries into Thrace and rebelled against Arcadius. He attempted to take his forces across the Hellespont into Asia, but was intercepted and defeated by Fravitta, another Goth who held the position of "magister militum praesentalis". Following his defeat, Gainas fled to the Danube with his remaining followers, but was ultimately defeated and killed by Uldin the Hun in Thrace.
