Returning thence to Rome, he crossed into Macedonia, and after blockading Pompey for almost four months behind mighty ramparts, finally routed him in the battle at Pharsalus, followed him in his flight to Alexandria, and when he learned that his rival had been slain, made war on King Ptolemy, whom he perceived to be plotting against his own safety as well; a war in truth of great difficulty, convenient neither in time nor place, but carried on during the winter season, within the walls of a wellprovisioned and crafty foeman, while Caesar himself was without supplies of any kind and ill-prepared. Victor in spite of all, he turned over the rule of Egypt to Cleopatra and her younger brother, fearing that if he made a province of it, it might one day under a headstrong governor be a source of revolution. From Alexandria he crossed to Syria, and from there went to Pontus, spurred on by the news that Pharnaces, son of Mithridates the Great, had taken advantage of the situation to make war, and was already flushed with numerous successes; but Caesar vanquished him in a single battle within five days after his arrival and four hours after getting sight of him, often remarking on Pompey’s good luck in gaining his principal fame as a general by victories over such feeble foemen. Then he overcame Scipio and Juba, who were patching up the remnants of their party in Africa, and the sons of Pompey in Spain.
