Next came the turn of Mamerkus, who had assembled near Katana a considerable force, strengthened by a body of Carthaginian allies under Giskon. He was attacked and defeated by Timoleon near the river Abolus, with a loss of two thousand men, many of them belonging to the Carthaginian division. We know nothing but the simple fact of this battle; which probably made serious impression upon the Carthaginians, since they speedily afterwards sent earnest propositions for peace, deserting their Sicilian allies. Peace was accordingly concluded; on terms however which left the Carthaginian dominion in Sicily much the same as it had been at the end of the reign of the elder Dionysius, as well as at the landing of Dion in Sicily.[382] The line of separation was fixed at the river Halykus, or Lykus, which flows into the southern sea near Herakleia Minoa, and formed the western boundary of the territory of Agrigentum. All westward of the Halykus was recognized as Carthaginian: but it was stipulated that if any Greeks within that territory desired to emigrate and become inmates of Syracuse, they should be allowed freely to come with their families and their property. It was farther covenanted that all the territory eastward of the Halykus should be considered not only as Greek, but as free Greek, distributed among so many free cities, and exempt from despots. And the Carthaginians formally covenanted that they would neither aid, nor adopt as ally, any Grecian despot in Sicily.[383] In the first treaty concluded by the elder Dionysius with the Carthaginians, it had been stipulated by an express article that the Syracusans should be subject to him.[384] Here is one of the many contrasts between Dionysius and Timoleon. [382] Diodor. xv. 17. Minoa (Herakleia) was a Carthaginian possession when Dion landed (Plutarch, Dion, c. 25). Cornelius Nepos (Timoleon, c. 2) states erroneously, that the Carthaginians were completely expelled from Sicily by Timoleon. [383] Plutarch, Timoleon, c. 34; Diodor. xvi. 82. [384] Diodor. xiii. 114.
