Bainobaudes (c. 320 - 357 AD) was a Roman soldier of Frank ancestry who served under emperors Constantius II and Julian.
[1] Bainobaudes was tribune of the scola Scutatiorum under the Caesar Julian during his campaigns against the Alamanni in Gaul.
[2] During a pincer movement led by Julian and the general Barbatio, a band of Alamanni slipped past them and attacked Lugdunum (Lyon).
Julian sent the tribunes Valentinian (the future emperor) and Bainobaudes to watch the road the raiders would have to return by.
The Alamann king Chnodomarius took advantage of the situation and attacked the Romans in detail, inflicting heavy losses.
