Pompey managed to escape before Caesar could capture him. Caesar decided to head for Spain, while leaving Italy under the control of Mark Antony. Caesar made an astonishing 27-day route-march to Spain, where he defeated Pompey's lieutenants. He then returned east, to challenge Pompey in Greece. There, in July 48 BC, at Dyrrhachium Caesar barely avoided a catastrophic defeat. He then decisively defeated Pompey, at the Battle of Pharsalus later that year.
