In 36 BC, Octavian and Agrippa set sail against Sextus. The fleet was badly damaged by storms and had to withdraw; Agrippa was left in charge of the second attempt. Thanks to superior technology and training, Agrippa and his men won decisive victories at Mylae and Naulochus, destroying all but seventeen of Sextus' ships and compelling most of his forces to surrender. Octavian, with his power increased, forced the triumvir Lepidus into retirement and entered Rome in triumph. Agrippa received the unprecedented honour of a naval crown decorated with the beaks of ships; as Dio remarks, this was "a decoration given to nobody before or since".
