In 386 he had a command in
Africa. Later the same year, he was
magister peditum per Thracias. 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. Promotus deployed his forces along the south bank and despatched some men to trick them by pretending to want payment to betray the Romans, but they in fact reported the plan to Promotus. 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. Theodosius, who was nearby, freed the surviving
Goths hoping to use them in his coming campaign against
Magnus Maximus. In 388, Promotus was promoted to
magister equitum in preparation for the campaign against Maximus. He presumably did well in the campaign, for he was rewarded with the consulship in 389. 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. == Death ==
