The battle of Pharsalia decided the fate of Pompey and the Republic. Pompey was at once driven to despair. He made no attempt to rally his forces, though he might still have collected a considerable army; but, regarding every thing as lost, he hurried to the sea-coast with a few friends. He embarked on board a merchant-ship at the mouth of the River Peneus, and first sailed to Lesbos, where he took on board his wife Cornelia, and from thence made for Cyprus. He now determined to seek refuge in Egypt, as he had been the means of restoring to his kingdom Ptolemy Auletes, the father of the young Egyptian monarch. On his death in B.C. 51 Ptolemy Auletes had left directions that his son should reign jointly with his elder sister Cleopatra. But their joint reign did not last long, for Ptolemy, or, rather, Pothinus and Achillas, his chief advisers, expelled his sister from the throne. Cleopatra collected a force in Syria, with which she invaded Egypt. The generals of Ptolemy were encamped opposite her, near Alexandria, when Pompey arrived off the coast and craved the protection of the young king. This request threw Pothinus and Achillas into great difficulty, for there were many of Pompey's old soldiers in the Egyptian army, and they feared he would become master of Egypt. They therefore determined to put him to death. Accordingly, they sent out a small boat, took Pompey on board with three or four attendants, and rowed for the shore. His wife and friends watched him from the ship, anxious to see in what manner he would be received by the king, who was standing on the edge of the sea with his troops. Just as the boat reached the shore, and Pompey was in the act of rising from his seat in order to step on land, he was stabbed in the back by Septimius, who had formerly been one of his centurions. Achillas and the rest then drew their swords; whereupon Pompey, without uttering a word, covered his face with his toga, and calmly submitted to his fate. He had just completed his 58th year. His head was cut off, and his body, which was cast naked upon the shore, was buried by his freedman Philippus, who had accompanied him from the ship. The head was brought to Caesar when he arrived in Egypt soon afterward, but he turned away from the sight, shed tears at the untimely end of his rival, and put his murderers to death. When news of the battle of Pharsalia reached Rome, various laws were passed which conferred supreme power upon Caesar. Though absent, he was nominated Dictator a second time, and for a whole year. He appointed M. Antonius his master of the Horse; and entered upon the office in September of this year (B.C. 48). He was also nominated to the Consulship for the next five years, though he did not avail himself of this privilege; and he was invested with the tribunicial power for life.
