Caesar departed from Egypt around April 47 BC, allegedly to confront Pharnaces II of Pontus, the son of Mithridates VI of Pontus, who was stirring up trouble for Rome in Anatolia. It is possible that Caesar, married to the prominent Roman woman Calpurnia, also wanted to avoid being seen together with Cleopatra when she had their son. He left three legions in Egypt, later increased to four, under the command of the freedman Rufio, to secure Cleopatra's tenuous position, but also perhaps to keep her activities in check.
