The same summer the Athenians in the twenty ships at Lade, blockading Miletus, made a descent at Panormus in the Milesian territory, and killed Chalcideus the Lacedaemonian commander, who had come with a few men against them, and the third day after sailed over and set up a trophy, which, as they were not masters of the country, was however pulled down by the Milesians. Meanwhile Leon and Diomedon with the Athenian fleet from Lesbos issuing from the Oenussae, the isles off Chios, and from their forts of Sidussa and Pteleum in the Erythraeid, and from Lesbos, carried on the war against the Chians from the ships, having on board heavy infantry from the rolls pressed to serve as marines. Landing in Cardamyle and in Bolissus they defeated with heavy loss the Chians that took the field against them and, laying desolate the places in that neighbourhood, defeated the Chians again in another battle at Phanae, and in a third at Leuconium. After this the Chians ceased to meet them in the field, while the Athenians devastated the country, which was beautifully stocked and had remained uninjured ever since the Median wars. Indeed, after the Lacedaemonians, the Chians are the only people that I have known who knew how to be wise in prosperity, and who ordered their city the more securely the greater it grew. Nor was this revolt, in which they might seem to have erred on the side of rashness, ventured upon until they had numerous and gallant allies to share the danger with them, and until they perceived the Athenians after the Sicilian disaster themselves no longer denying the thoroughly desperate state of their affairs. And if they were thrown out by one of the surprises which upset human calculations, they found out their mistake in company with many others who believed, like them, in the speedy collapse of the Athenian power. While they were thus blockaded from the sea and plundered by land, some of the citizens undertook to bring the city over to the Athenians. Apprised of this the authorities took no action themselves, but brought Astyochus, the admiral, from Erythrae, with four ships that he had with him, and considered how they could most quietly, either by taking hostages or by some other means, put an end to the conspiracy.
While the Chians were thus engaged, a thousand Athenian heavy infantry and fifteen hundred Argives (five hundred of whom were light troops furnished with armour by the Athenians), and one thousand of the allies, towards the close of the same summer sailed from Athens in forty-eight ships, some of which were transports, under the command of Phrynichus, Onomacles, and Scironides, and putting into Samos crossed over and encamped at Miletus. Upon this the Milesians came out to the number of eight hundred heavy infantry, with the Peloponnesians who had come with Chalcideus, and some foreign mercenaries of Tissaphernes, Tissaphernes himself and his cavalry, and engaged the Athenians and their allies. While the Argives rushed forward on their own wing with the careless disdain of men advancing against Ionians who would never stand their charge, and were defeated by the Milesians with a loss little short of three hundred men, the Athenians first defeated the Peloponnesians, and driving before them the barbarians and the ruck of the army, without engaging the Milesians, who after the rout of the Argives retreated into the town upon seeing their comrades worsted, crowned their victory by grounding their arms under the very walls of Miletus. Thus, in this battle, the Ionians on both sides overcame the Dorians, the Athenians defeating the Peloponnesians opposed to them, and the Milesians the Argives. After setting up a trophy, the Athenians prepared to draw a wall round the place, which stood upon an isthmus; thinking that, if they could gain Miletus, the other towns also would easily come over to them.
Meanwhile about dusk tidings reached them that the fifty-five ships from Peloponnese and Sicily might be instantly expected. Of these the Siceliots, urged principally by the Syracusan Hermocrates to join in giving the finishing blow to the power of Athens, furnished twenty-two- twenty from Syracuse, and two from Silenus; and the ships that we left preparing in Peloponnese being now ready, both squadrons had been entrusted to Therimenes, a Lacedaemonian, to take to Astyochus, the admiral. They now put in first at Leros the island off Miletus, and from thence, discovering that the Athenians were before the town, sailed into the Iasic Gulf, in order to learn how matters stood at Miletus. Meanwhile Alcibiades came on horseback to Teichiussa in the Milesian territory, the point of the gulf at which they had put in for the night, and told them of the battle in which he had fought in person by the side of the Milesians and Tissaphernes, and advised them, if they did not wish to sacrifice Ionia and their cause, to fly to the relief of Miletus and hinder its investment.
Accordingly they resolved to relieve it the next morning.
