After the siege, the Asemuntians attacked the withdrawing Huns and even captured some Hunnic prisoners.
In 447 Attila's Huns crossed the Danube and defeated the Eastern Roman army at the Battle of the Utus.
[5] As the Huns returned north after plundering Thrace, some of them besieged the fortified town of Asemus, which was situated on a hill near the Danube.
The defenders then pursued the fleeing Huns, capturing a number of them and seizing their booty as well as rescuing many Roman prisoners.
[6][7][8] Following this conflict, Attila demanded the return of the captured Huns and that a ransom be paid for the freed Romans.
