The Greuthungi of King Odotheus gathered on the north bank of the Danube and asked for admission to the Empire, presumably on the same terms as the Tervingi ten years previously.
When the Greuthungi attempted to cross the river, instead of a sleeping camp they were confronted with a fleet of river-craft which proceeded to sink all the enemy canoes.
Claudian says the island of Peuce was heaped high with bodies and the river mouths ran red with blood.
While Theodosius was travelling back to the East through Thessalonica and having various adventures, Promotus saved him from a barbarian attack, and may have been rewarded for this with a higher command.
Rufinus then persuaded Theodosius to send Promotus out on exercises with the troops, and sent a company of barbarians who ambushed and killed him.
