(M671) Meanwhile the Syracusans defeated a portion of the Carthaginian fleet, and a terrific pestilence overtook the army before the city. The military strength of the Carthaginians was prostrated by the terrible malady, which swept away one hundred and fifty thousand persons in the camp. When thus weakened and demoralized, the Carthaginians were attacked by the Syracusans, and were completely routed. The fleet was also defeated and set on fire, and the conflagration reached the camp, which was thus attacked by pestilence, fire, and sword. The disaster was fatal to the Carthaginians, and retreat was necessary. Imilco dispatched a secret envoy to Dionysius, offering three hundred talents if the fleet was allowed to sail away unmolested to Africa. This could not be permitted, but Imilco and the native Carthaginians were allowed to retire. The remaining part of the army, deprived of their head, was destroyed, with the exception of the Sikels, who knew the roads, and made good their escape. (M672) This immense disaster, greater than that the Athenians had suffered under Nicias, produced universal mourning and distress at Carthage, while the miserable Imilco vainly endeavoring to disarm the wrath of his countrymen, shut himself up in his house, and starved himself to death. This misfortune led also to a revolt of the African allies, which was subdued with difficulty, while the power of Carthage in Sicily was reduced to the lowest ebb. Dionysius was now left to push his conquests in other directions, and Syracuse was rescued from impending ruin. (M673) Dionysius had now reigned eleven years, with absolute power. The pestilence, and the treachery of Imilco, had freed him of the Carthaginians. But a difficulty arose as to the payment of his mercenaries, which he compromised by giving them the rich territory of Leontini, so that ten thousand quitted Syracuse, and took up their residence in the town. The cost of maintaining a large standing army was exceeding burdensome, and we only wonder how the tyrant found means to pay it, and prosecute at the same time such great improvements. (M674) He now directed his attention to the Sikels, in the interior of the island, and took several of their towns, but from one of them he met with desperate resistance, find came near losing his life from a wound by a spear which penetrated his cuirass. This repulse caused the Carthaginians to rally in the west of the island, under Magon, with an army of eighty thousand. But he was repulsed by Dionysius, and concluded a truce with him, which gave the latter leisure to make himself master of Messene and Taurominium—the two most important maritime posts on the Italian side of Sicily, and thus prepare for the invasion of the Greek cities in the south of Italy, B.C. 391.
