Caesar went to Egypt in pursuit of Pompey, and upon his arrival there he became involved in a war, which detained him several months, and gave the remains of the Pompeian party time to rally and to make fresh preparations for continuing the struggle. The war in Egypt, usually called the Alexandrine War, arose from Caesar's resolving to settle the disputes respecting the succession to the kingdom. He determined that Cleopatra, whose fascinations completely won his heart, and her brother Ptolemy, should reign in common, according to the provisions of their father's will; but as this decision was opposed by the guardians of the young king, a war broke out between them and Caesar, in which he was for some time exposed to great danger on account of the small number of his troops. But, having received re-enforcements, he finally prevailed, and placed Cleopatra and her younger brother on the throne, the elder having perished in the course of the contest. Cleopatra afterward joined Caesar at Rome, and bore him a son named Caesarion. After bringing the Alexandrine War to a close, toward the end of March, B.C. 47, Caesar marched through Syria into Pontus in order to attack Pharnaces, the son of the celebrated Mithridates, who had defeated Cn. Domitius Calvinus, one of Caesar's lieutenants. This war, however, did not detain him long; for Pharnaces, venturing to come to an open battle with the Dictator, was utterly defeated on the 2d of August near Zela. It was in reference to this victory that Caesar sent the celebrated laconic dispatch to the Senate, _Veni, vidi, vici_, "I came, I saw, I conquered." He then proceeded to Rome, caused himself to be appointed Dictator for another year, and nominated M. AEmilius Lepidus his Master of the Horse. At the same time he quelled a formidable mutiny of his troops which had broken out in Campania.
