In 43 BC he was proscribed, but managed to escape to the camp of Brutus and Cassius. After the Battle of Philippi in 42 BC, he went over to Antony, but subsequently transferred his support to Octavian. In 31 BC, Corvinus was appointed consul in place of Antony and took part in the Battle of Actium. He subsequently held commands in the East and suppressed the revolt in Gallia Aquitania; for this latter feat he celebrated a triumph in 27 BC.
