History of the Peloponnesian War

In the meantime not only had the Chians strengthened their command of the sea, but Astyochus also and the Peloponnesians at Miletus, learning the result of the sea-fight and about the departure of Strombichides and his fleet, took courage.

So Astyochus sailed along the coast to Chios with two ships, took on the ships which were there, and with what was now the entire fleet advanced against Samos; but when the Athenians, because their two factions entertained suspicions of one another, would not come out to meet him, he sailed back again to Miletus. For it was about this time, or somewhat earlier, that the democracy at Athens was being overthrown.

When the envoys led by Peisander had come to Samos from Tissaphernes, they had got matters in the army itself still more firmly under their control and had instigated the influential men among the Samians also to attempt in concert with them to establish an oligarchy, although the Samians had risen in revolt against their own countrymen in order to avoid being governed by an oligarchy.
