After initial success, Magnentius was defeated by Constantius II at the Battle of Mursa Major. The people of Treveri revolted and closed their gates against Decentius. Incited by Constantius, the Germanic Allemanni tribe under their chief Chnodomar invaded Gaul, defeated Decentius, and besieged him in Senonae. It was there that he learned of Magnentius' defeat at the Battle of Mons Seleucus and subsequent suicide. On 18 August 353, Decentius hanged himself in the besieged city, ending the civil war. |
