(M669) The siege occupied the summer, and Dionysius, triumphant, returned to Syracuse. But Imilco being elevated to the chief magistracy of Carthage, brought over to Sicily an overwhelming force, collected from all Africa and Iberia, amounting to one hundred thousand men, afterward re-enforced by thirty thousand more, at the lowest estimate, with four hundred ships and six hundred transports. This army disembarked at Panormus, on the northwestern side of the island (Palermo) retook Motya, regained Eryx, then marched east and captured Messene, at the extreme eastern part of the island near Italy, which prevented Dionysius from getting aid from Italy. The Sikels also rebelled, and Dionysius, greatly disquieted by the loss of all his conquests, and by approaching dangers, strengthened the fortifications of Syracuse, to which he had retired, and made preparations to resist the enemy. He had still a force of thirty thousand foot and three thousand horse, and one hundred and eighty ships of war. He sent also to Sparta for aid. He then advanced to Catana. A naval battle took place off this city, gained by the Carthaginians, from superior numbers. One hundred of the Syracusan ships were destroyed, with twenty thousand men, B.C. 395. (M670) After this defeat, Dionysius retreated to Syracuse with his land forces, amid great discontent, and invoked the aid of Sparta and Corinth. Imilco advanced also to Syracuse, while his victorious fleet occupied the great harbor—a much more imposing armament than that the Athenians had at the close of the Persian war. The total number of vessels was two thousand. Imilco established his head-quarters at the temple of Zeus Olympius, one mile and a half from the city, and allowed his troops thirty days for plunder over the Syracusan territory; then he established fortified posts, and encircled his camp with a wall, and set down in earnest to reduce the city to famine. But as he was not master of Epipolæ, as Nicias was, Syracuse was able to communicate with the country around, both west and north, and also found means to secure supplies by sea.
