In 44 , probably shortly before or after the assassination of Caesar, Arabio returned to Africa at the urging of Gnaeus Pompeius' son, Sextus Pompeius. From Africa, he sent men back to Hispania for military training. He reclaimed his father's kingdom with relative ease, forcing Bocchus into exile, and then contrived to assassinate Sittius through a stratagem. News of his conquests had reached Rome by 14 June 44, when Cicero mentions it in a letter to Atticus. His success is sometimes attributed to the Roman training of the forces he had brought with him back to Africa, but is more likely due to the allegiance of the population to one of their own.
