In Rome the three main Caesarian leaders ( Antony , Octavian and Marcus Aemilius Lepidus ) , who controlled almost all the Roman army in the west , had crushed the opposition of the senate and established the second triumvirate . One of their first tasks was to destroy the Liberators ’ forces , not only to get full control of the Roman world , but also to avenge Caesar ’s death
