Hamilcar Barca
The last condition is mentioned by Polybius in place of the one regarding not making war on Syracuse. It is possible that Hamilcar Barca secured the last clause after the initial conditions, which were more favorable to Carthage, was altered by Rome with a harsher one. Hamilcar Barca gathered the Carthaginian soldiers from Drepana and Eryx at Lilybaeum, surrendered his command, returned to Carthage and retired to private life, leaving Gisco and the Carthaginian government to pay off his soldiers. Whatever was the motivation behind this act, it was resented by the mercenaries left behind in Sicily.
