History of the Peloponnesian War

The same summer, those Athenians that with twenty galleys lay in the isle of Lada before Miletus, landing in the territory of Miletus at Panormus, slew Chalcideus, the Lacedaemonian commander, that came out against them but with a few, and set up a trophy, and the third day after departed. But the Milesians pulled down the trophy, as erected where the Athenians were not masters.

Leon and Diomedon, with the Athenian galleys that were at Lesbos, made war upon the Chians by sea from the isles called Oenussae, which lie before Chios, and from Sidussa and Pteleum (forts they held in Erythraea), and from Lesbos. They that were aboard were men of arms of the roll, compelled to serve in the fleet. With these they landed at Cardamyle;

and having overthrown the Chians that made head in a battle at Bolissus, and slain many of them, they recovered from the enemy all the places of that quarter. And again they overcame them in another battle at Phanae, and in a third at Leuconium. After this, the Chians went out no more to fight; by which means the Athenians made spoil of their territory, excellently well furnished.

For except it were the Lacedaemonians, the Chians were the only men that I have heard of that had joined advisedness to prosperity, and the more their city increased, had carried the more respect in the administration thereof to assure it.

Nor ventured they now to revolt (lest any man should think that, in this act at least, they regarded not what was the safest) till they had many and strong confederates with whose help to try their fortune, nor till such time as they perceived the people of Athens (as they themselves could not deny) to have their estate after the defeat in Sicily reduced to extreme weakness. And if through human misreckoning they miscarried in aught, they erred with many others, who in like manner had an opinion that the state of the Athenians would quickly have been overthrown.

Being therefore shut up by sea, and having their lands spoiled, some within undertook to make the city return unto the Athenians. Which though the magistrates perceived, yet they themselves stirred not; but having received Astyochus into the city with four galleys that were with him from Erythraea, they took advice together, how by taking hostages, or some other gentle way, to make them give over the conspiracy. Thus stood the business with the Chians.
