About the same time the sixteen Peloponnesian ships, which had served with Gylippus in Sicily throughout the war, were on their way home; and as they were off Leucadia they were intercepted and roughly handled by the twenty-seven Athenian ships under the command of Hippocles son of Menippus, who was on the look-out for the ships from Sicily; but all except one escaped the Athenians and sailed into Corinth.
Meanwhile Chalcideus and Alcibiades as they sailed for Chios seized all whom they encountered, that their coming might not be reported. The first point on the mainland at which they touched was Corycus,[*](There were several places called Corycus. This one was the southernmost point of the Erythraean peninsula, about forty miles from Chios. Cf. Livy xxxvii. 12, Corycum Teiorum promonturium.) where they released their captives; then after a conference with some Chians who were co-operating with them and who urged them to sail to Chios without giving any notice, they arrived at Chios suddenly.
Now the people at large were in a state of wonderment and consternation, but the oligarchs had arranged that the council should chance to have just assembled; speeches were accordingly made by Chalcideus and Alcibiades, who announced that many additional ships were on the way, but did not disclose the fact of the blockade of their fleet at Peiraeum, and then the Chians revolted from Athens, and so later on did the Erythraeans.
