Meanwhile, the forty ships of the Peloponnesians that had gone to the relief of the Lesbians, and which we left flying across the open sea, pursued by the Athenians, were caught in a storm off Crete, and scattering from thence made their way to Peloponnese, where they found at Cyllene thirteen Leucadian and Ambraciot galleys, with Brasidas, son of Tellis, lately arrived as counsellor to Alcidas; the Lacedaemonians, upon the failure of the Lesbian expedition, having resolved to strengthen their fleet and sail to Corcyra, where a revolution had broken out, so as to arrive there before the twelve Athenian ships at Naupactus could be reinforced from Athens. Brasidas and Alcidas began to prepare accordingly.

The Corcyraean revolution began with the return of the prisoners taken in the sea-fights off Epidamnus. These the Corinthians had released, nominally upon the security of eight hundred talents given by their proxeni, but in reality upon their engagement to bring over Corcyra to Corinth. These men proceeded to canvass each of the citizens, and to intrigue with the view of detaching the city from Athens. Upon the arrival of an Athenian and a Corinthian vessel, with envoys on board, a conference was held in which the Corcyraeans voted to remain allies of the Athenians according to their agreement, but to be friends of the Peloponnesians as they had been formerly. Meanwhile, the returned prisoners brought Peithias, a volunteer proxenus of the Athenians and leader of the commons, to trial, upon the charge of enslaving Corcyra to Athens. He, being acquitted, retorted by accusing five of the richest of their number of cutting stakes in the ground sacred to Zeus and Alcinous; the legal penalty being a stater for each stake. Upon their conviction, the amount of the penalty being very large, they seated themselves as suppliants in the temples to be allowed to pay it by instalments; but Peithias, who was one of the senate, prevailed upon that body to enforce the law; upon which the accused, rendered desperate by the law, and also learning that Peithias had the intention, while still a member of the senate, to persuade the people to conclude a defensive and offensive alliance with Athens, banded together armed with daggers, and suddenly bursting into the senate killed Peithias and sixty others, senators and private persons; some few only of the party of Peithias taking refuge in the Athenian galley, which had not yet departed.

After this outrage, the conspirators summoned the Corcyraeans to an assembly, and said that this would turn out for the best, and would save them from being enslaved by Athens: for the future, they moved to receive neither party unless they came peacefully in a single ship, treating any larger number as enemies. This motion made, they compelled it to be adopted, and instantly sent off envoys to Athens to justify what had been done and to dissuade the refugees there from any hostile proceedings which might lead to a reaction.

Upon the arrival of the embassy, the Athenians arrested the envoys and all who listened to them, as revolutionists, and lodged them in Aegina. Meanwhile a Corinthian galley arriving in the island with Lacedaemonian envoys, the dominant Corcyraean party attacked the commons and defeated them in battle. Night coming on, the commons took refuge in the Acropolis and the higher parts of the city, and concentrated themselves there, having also possession of the Hyllaic harbour; their adversaries occupying the market-place, where most of them lived, and the harbour adjoining, looking towards the mainland.

The next day passed in skirmishes of little importance, each party sending into the country to offer freedom to the slaves and to invite them to join them. The mass of the slaves answered the appeal of the commons; their antagonists being reinforced by eight hundred mercenaries from the continent.

After a day’s interval hostilities recommenced, victory remaining with the commons, who had the advantage in numbers and position, the women also valiantly assisting them, pelting with tiles from the houses, and supporting the melee with a fortitude beyond their sex. Towards dusk, the oligarchs in full rout, fearing that the victorious commons might assault and carry the arsenal and put them to the sword, fired the houses round the marketplace and the lodging-houses, in order to bar their advance; sparing neither their own, nor those of their neighbours; by which much stuff of the merchants was consumed and the city risked total destruction, if a wind had come to help the flame by blowing on it. Hostilities now ceasing, both sides kept quiet, passing the night on guard, while the Corinthian ship stole out to sea upon the victory of the commons, and most of the mercenaries passed over secretly to the continent.

The next day the Athenian general, Nicostratus, son of Diitrephes, came up from Naupactus with twelve ships and five hundred Messenian heavy infantry. He at once endeavoured to bring about a settlement, and persuaded the two parties to agree together to bring to trial ten of the ringleaders, who presently fled, while the rest were to live in peace, making terms with each other, and entering into a defensive and offensive alliance with the Athenians. This arranged, he was about to sail away, when the leaders of the commons induced him to leave them five of his ships to make their adversaries less disposed to move, while they manned and sent with him an equal number of their own. He had no sooner consented, than they began to enroll their enemies for the ships; and these, fearing that they might be sent off to Athens, seated themselves as suppliants in the temple of the Dioscuri. An attempt on the part of Nicostratus to reassure them and to persuade them to rise proving unsuccessful, the commons armed upon this pretext, alleging the refusal of their adversaries to sail with them as a proof of the hollowness of their intentions, and took their arms out of their houses, and would have dispatched some whom they fell in with, if Nicostratus had not prevented it. The rest of the party, seeing what was going on, seated themselves as suppliants in the temple of Hera, being not less than four hundred in number; until the commons, fearing that they might adopt some desperate resolution, induced them to rise, and conveyed them over to the island in front of the temple, where provisions were sent across to them.

At this stage in the revolution, on the fourth or fifth day after the removal of the men to the island, the Peloponnesian ships arrived from Cyllene where they had been stationed since their return from Ionia, fifty-three in number, still under the command of Alcidas, but with Brasidas also on board as his adviser; and dropping anchor at Sybota, a harbour on the mainland, at daybreak made sail for Corcyra.

The Corcyraeans in great confusion and alarm at the state of things in the city and at the approach of the invader, at once proceeded to equip sixty vessels, which they sent out, as fast as they were manned, against the enemy, in spite of the Athenians recommending them to let them sail out first, and to follow themselves afterwards with all their ships together. Upon their vessels coming up to the enemy in this straggling fashion, two immediately deserted: in others the crews were fighting among themselves, and there was no order in anything that was done; so that the Peloponnesians, seeing their confusion, placed twenty ships to oppose the Corcyraeans, and ranged the rest against the twelve Athenian ships, amongst which were the two vessels Salaminia and Paralus.

While the Corcyraeans, attacking without judgment and in small detachments, were already crippled by their own misconduct, the Athenians, afraid of the numbers of the enemy and of being surrounded, did not venture to attack the main body or even the centre of the division opposed to them, but fell upon its wing and sank one vessel; after which the Peloponnesians formed in a circle, and the Athenians rowed round them and tried to throw them into disorder. Perceiving this, the division opposed to the Corcyraeans, fearing a repetition of the disaster of Naupactus, came to support their friends, and the whole fleet now bore down, united, upon the Athenians, who retired before it, backing water, retiring as leisurely as possible in order to give the Corcyraeans time to escape, while the enemy was thus kept occupied. Such was the character of this sea-fight, which lasted until sunset.
