Following Caesar's assassination, Caesar's ally Ventidius Bassus made attempts to recreate the 7th, 8th and 9th legions, but "it is not clear that any of these survived even to the time of Philippi". Octavian later recalled the veterans of the Ninth to fight against the rebellion of Sextus Pompeius in Sicily. After defeating Sextus, they were sent to the province of Macedonia. The Ninth remained with Octavian in his war of 31 BC against Mark Antony and fought by his side in the Battle of Actium.
