During the Perusine War (modern Perugia) between 41 BC-40 BC, Julia left Rome, although Octavian (future Roman Emperor Augustus) treated her with kindness. She never trusted Sextus Pompeius. When Sextus Pompeius was in Sicily, Julia had sent to Greece for Antony, a distinguished escort and convoy of triremes. After the reconciliation of the triumvirs, Julia returned with Antony to Italy in 39 BC and was probably present at the meeting with Sextus Pompeius at Misenum.
