As soon as they had brought the Libyan war to a conclusion the Carthaginian government collected an army and despatched it under the command of Hamilcar to Iberia. This general took over the command of the troops, and with his son Hannibal, then nine years old, crossing by the Pillars of Hercules, set about recovering the Carthaginian possessions in Iberia. He spent nine years in Iberia, and after reducing many Iberian tribes by war or diplomacy to obedience to Carthage he died in a manner worthy of his great achievements; for he lost his life in a battle against the most warlike and powerful tribes, in which he showed a conspicuous and even reckless personal gallantry. The Carthaginians appointed his son-in-law Hasdrubal to succeed him, who was at the time in command of the fleet. [Sidenote: Illyricum.] +2.+ It was at this same period that the Romans for the first time crossed to Illyricum and that part of Europe with an army. The history of this expedition must not be treated as immaterial; but must be carefully studied by those who wish to understand clearly the story I have undertaken to tell, and to trace the progress and consolidation of the Roman Empire. [Sidenote: B.C. 233-232.] [Sidenote: Siege of Medion in Acarnania.] Agron, king of the Illyrians, was the son of Pleuratus, and possessed the most powerful force, both by land and sea, of any of the kings who had reigned in Illyria before him. By a bribe received from Demetrius he was induced to promise help to the Medionians, who were at that time being besieged by the Aetolians, who, being unable to persuade the Medionians to join their league, had determined to reduce the city by force. They accordingly levied their full army, pitched their camp under the walls of the city, and kept up a continuous blockade, using every means to force their way in, and every kind of siege-machine. But when the time of the annual election of their Strategus drew near, the besieged being now in great distress, and seeming likely every day to surrender, the existing Strategus made an appeal to the Aetolians. He argued that as he had had during his term of office all the suffering and the danger, it was but fair that when they got possession of the town he should have the apportioning of the spoil, and the privilege of inscribing his name on such arms as should be preserved for dedication. This was resisted by some, and especially by those who were candidates for the office, who urged upon the Assembly not to prejudge this matter, but to leave it open for fortune to determine who was to be invested with this honour; and, finally, the Aetolians decided that whoever was general when the city was taken should share the apportioning of the spoils, and the honour of inscribing the arms, with his predecessor.
