Alliance between Carthage and Syracuse

In Sicily king Hiero had during the years of peace maintained a policy of neutrality, so far as he could do so with safety, and he had shown a disposition to accommodate the Carthaginians during the perilous crises after the peace with Rome, particularly by sending supplies of corn.  There is no doubt that he saw with the utmost regret a renewed breach between Carthage and Rome; but he had no power to avert it, and when it occurred he adhered with well-calculated fidelity to Rome.  But soon afterwards (in the autumn of 538) death removed the old man after a reign of fifty-four years.  The grandson and successor of the prudent veteran, the young and incapable Hieronymus, entered at once into negotiations with the Carthaginian diplomatists; and, as they made no difficulty in consenting to secure to him by treaty, first, Sicily as far as the old Carthagino-Sicilian frontier, and then, when he rose in the arrogance of his demands, the possession even of the whole island, he entered into alliance with Carthage, and ordered the Syracusan fleet to unite with the Carthaginian which had come to threaten Syracuse.  The position of the Roman fleet at Lilybaeum, which already had to deal with a second Carthaginian squadron stationed near the Aegates, became all at once very critical, while at the same time the force that was in readiness at Rome for embarkation to Sicily had, in consequence of the defeat at Cannae, to be diverted to other and more urgent objects.

Capua and Most of the Communities of Lower Italy Pass over to Hannibal

Above all came the decisive fact, that now at length the fabric of the Roman confederacy began to be unhinged, after it had survived unshaken the shocks of two severe years of war.  There passed over to the side of Hannibal Arpi in Apulia, and Uzentum in Messapia, two old towns which had been greatly injured by the Roman colonies of Luceria and Brundisium; all the towns of the Bruttii—­who took the lead—­with the exception of the Petelini and the Consentini who had to be besieged before yielding; the greater portion of the Lucanians; the Picentes transplanted into the region of Salernum; the Hirpini; the Samnites with the exception of the Pentri; lastly and chiefly, Capua the second city of Italy, which was able to bring into the field 30,000 infantry and 4000 horse, and whose secession determined that of the neighbouring towns Atella and Caiatia.  The aristocratic party, indeed, attached by many ties to the interest of Rome everywhere, and more especially in Capua, very earnestly opposed this change of sides, and the obstinate internal conflicts which arose regarding it diminished not a little the advantage which Hannibal derived from these accessions.  He found himself obliged, for instance, to have one of the leaders of the aristocratic party in Capua, Decius Magius, who even after the entrance of the Phoenicians obstinately contended for the Roman alliance, seized and conveyed to Carthage;
