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.
After this three ships were detached from the fleet and brought about the revolt of Clazomenae. And the Clazomenians immediately crossed over to the mainland and fortified Polichne, on the chance that they themselves might have need of it in case they should withdraw from the island[*](According to Pausanias (7.3.9), the Clazomenians had removed to the island through fear of the Persians.) on which they lived. These peoples, then, being in revolt, were all engaged in fortifying and preparing for war.
News of the revolt of Chios came quickly to Athens, and they felt that the danger which encompassed them was by now great and manifest, and that the rest of their allies would not be inclined to keep quiet when the greatest state of all had seceded. And so they took up the question of the fund of a thousand talents,[*](cf. ii. 24. Pericles had set this fund aside in the first year of the war, to be touched only in case a hostile fleet threatened the Peiraeus.) which during the whole war they had jealously refrained from touching, and under the influence of their consternation immediately rescinded the penalties which had been imposed upon any speaker who should propose to touch this money, or any presiding officer who should put such a proposal to a vote, and then voted to use this fund and man a considerable number of ships. They also voted that of the ships which were employed in the blockade at Peiraeum there should be sent at once the eight that, leaving guard-duty, had gone in pursuit of the fleet under Chalcideus, but after failing to overtake it had returned to their post—the commander of these eight being Strombichides son of Diotimus—and that soon afterwards twelve others under Thrasycles should leave the blockade and go to the rescue.
