Constantine was forced to surrender to Constantius when his troops on the Rhine left him for another usurper, Jovinus.
Jovinus fled for his life, but was besieged and captured in Valentia (Valence, Drôme) and taken to Narbo (Narbonne), where Caius Posthumus Dardanus, the praetorian prefect (governor) in Gaul, who had remained loyal to Honorius, had him executed.
Jovinus |
After defeating Jovinus, the Visigoths came into renewed conflict with Honorius; this conflict culminated with the siege of Bazas in 414.
The first was Severus, the emperor's comes domesticorum, soon replaced by Jovinus, the magister equitum; rumours of disasters dogged them, however, and it took almost 15 months before a capable replacement was sent.
Guntram of Burgundy later had Jovinus arrested as he travelled with Theodore, Bishop of Marseille, to meet Childebert II, because Guntram was then in rivalry concerning the diocese of Marseille.
When Julian decided to move against Constantius in a bid for power, Nevitta was one of his two generals, the other being Jovinus.
