The Syracusans had now gained a decisive victory at sea, where until now they had feared the reinforcement brought by Demosthenes, and deep, in consequence, was the despondency of the Athenians, and great their disappointment, and greater still their regret for having come on the expedition. These were the only cities that they had yet encountered, similar to their own in character, under democracies like themselves, which had ships and horses, and were of considerable magnitude. They had been unable to divide and bring them over by holding out the prospect of changes in their governments, or to crush them by their great superiority in force, but had failed in most of their attempts, and being already in perplexity, had now been defeated at sea, where defeat could never have been expected, and were thus plunged deeper in embarrassment than ever.
Meanwhile the Syracusans immediately began to sail freely along the harbour, and determined to close up its mouth, so that the Athenians might not be able to steal out in future, even if they wished. Indeed, the Syracusans no longer thought only of saving themselves, but also how to hinder the escape of the enemy;thinking, and thinking rightly, that they were now much the stronger, and that to conquer the Athenians and their allies by land and sea would win them great glory in Hellas. The rest of the Hellenes would thus immediately be either freed or released from apprehension, as the remaining forces of Athens would be henceforth unable to sustain the war that would be waged against her; while they, the Syracusans, would be regarded as the authors of this deliverance, and would be held in high admiration, not only with all men now living but also with posterity. Nor were these the only considerations that gave dignity to the struggle. They would thus conquer not only the Athenians but also their numerous allies, and conquer not alone, but with their companions in arms, commanding side by side with the Corinthians and Lacedaemonians, having offered their city to stand in the van of danger, and having been in a great measure the pioneers of naval success.
Indeed, there were never so many peoples assembled before a single city, if we except the grand total gathered together in this war under Athens and Lacedaemon. The following were the states on either side who came to Syracuse to fight for or against Sicily, to help to conquer or defend the island. Right or community of blood was not the bond of union between them, so much as interest or compulsion as the case might be. The Athenians themselves being Ionians went against the Dorians of Syracuse of their own free will; and the peoples still speaking Attic and using the Athenian laws, the Lemnians, Imbrians, and Aeginetans, that is to say the then occupants of Aegina, being their colonists, went with them. To these must be also added the Hestiaeans dwelling at Hestiaea in Euboea. Of the rest some joined in the expedition as subjects of the Athenians, others as independent allies, others as mercenaries. To the number of the subjects paying tribute belonged the Eretrians, Chalcidians, Styrians, and Carystians from Euboea; the Ceans, Andrians, and Tenians from the islands; and the Milesians, Samians, and Chians from Ionia. The Chians, however, joined as independent allies, paying no tribute, but furnishing ships. Most of these were Ionians and descended from the Athenians, except the Carystians, who are Dryopes, and although subjects and obliged to serve, were still Ionians fighting against Dorians. Besides these there were men of Aeolic race, the Methymnians, subjects who provided ships, not tribute, and the Tenedians and Aenians who paid tribute. These Aeolians fought against their Aeolian founders, the Boeotians in the Syracusan army, because they were obliged, while the Plataeans, the only native Boeotians opposed to Boeotians, did so upon a just quarrel. Of the Rhodians and Cytherians, both Dorians, the latter, Lacedaemonian colonists, fought in the Athenian ranks against their Lacedaemonian countrymen with Gylippus; while the Rhodians, Argives by race, were compelled to bear arms against the Dorian Syracusans and their own colonists, the Geloans, serving with the Syracusans. Of the islanders round Peloponnese, the Cephallenians and Zacynthians accompanied the Athenians as independent allies, although their insular position really left them little choice in the matter, owing to the maritime supremacy of Athens, while the Corcyraeans, who were not only Dorians but Corinthians, were openly serving against Corinthians and Syracusans, although colonists of the former and of the same race as the latter, under colour of compulsion, but really out of free will through hatred of Corinth. The Messenians, as they are now called in Naupactus and from Pylos, then held by the Athenians, were taken with them to the war. There were also a few Megarian exiles, whose fate it was to be now fighting against the Megarian Selinuntines.
