Question: How old was the person who escaped to Africa when Cleopatra ascended to the throne? Passage:Caesar crossed the Rubicon accompanied by the XIII Legion to take power from the senate in the same way that Sulla had done in the past. Formally declared an enemy of the state, Caesar pursued the Senatorial party, now led by Pompey, who abandoned the city to raise arms in Greece. Cato was sent to Sicily to secure control of the grain supply. After securing control of Italy, Caesar sent the praetor Curio with four legions to Sicily. Cato's garrison was insufficient to withstand a force of this magnitude, he abandoned the island and went to Greece to join Pompey. After first reducing Caesar's army at the siege battle of Dyrrhachium, where Cato commanded the port, the army led by Pompey was ultimately defeated by Caesar in the Battle of Pharsalus (Cato wasn't present during the battle, Pompey had left him in command of Dyrrhachium). Cato and Metellus Scipio, however, did not concede defeat and escaped to the province of Africa with fifteen cohorts to continue resistance from Utica. Caesar pursued Cato and Metellus Scipio after installing the queen Cleopatra VII on the throne of Egypt, and in February 46 BC the outnumbered Caesarian legions defeated the army led by Metellus Scipio at the Battle of Thapsus. Acting against his usual strategy of clemency, Caesar did not accept surrender of Scipio's troops, but had them all slaughtered.
