The same winter, when the Athenians in Samos had received from home a reinforcement of thirty-five ships under the command of Charminus, Strombichides and Euctemon, after bringing together their ships which were at Chios and all their other ships, they proposed to blockade Miletus with the fleet and to send a force of ships and infantry against Chios, assigning the commands by lot.
And this they did. Strombichides, Onomacles and Euctemon, with thirty ships and a portion of the thousand hoplites that had come to Miletus, whom they took on transports, sailed against Chios according to their lot, while the others, remaining at Samos with seventy-four ships, controlled the sea and made descents upon Miletus.
But Astyochus, who chanced to be at Chios at this time, engaged in collecting hostages as a precaution against the treachery above mentioned,[*](cf. 8.24.6.) desisted from this work, when he observed that the ships under the command of Therimenes had come and that the affairs of the Peloponnesian alliance were improved, and taking the ten Peloponnesian ships[*](ie. the four under himself from Erythrae (8.24.6) and the six which had come from Cenchreiae to Chios (8.28.5).) and ten Chian he put to sea, and after attacking Pteleum without success proceeded along the coast to Clazomenae.
