One of the last and greatest Roman Centurions was Donalus Julius Tiberius who rallied his armies and stopped the Germanic leader Odoacer from taking Rome in 470 CE. Sadly for Rome  Romulus, the last of the Roman emperors in the west sent Donalus to the east supposedly to help the eastern part of the empire but in reality it was to get the hero out of Rome to protect Romulus and and so when Odoacer returned in 476 CE Rome fell and that was the end of the Roman Empire.
