History of the Peloponnesian War

For the intention of Alcibiades, that was acquainted with the principal Milesians, was to prevent the fleet which was to come from Peloponnesus and to turn these cities first, that the honour of it might be ascribed to the Chians, to himself, to Chalcideus, and (as he had promised) to Endius that set them out, as having brought most of the cities to revolt with the forces of the Chians only and of those galleys that came with Chalcideus.

So these, for the greatest part of their way undiscovered, and arriving not much sooner than Strombichides and Thrasycles (who now, chancing to be present with [those] twelve galleys from Athens, followed them with Strombichides), caused the Milesians to revolt. The Athenians following them at the heels with nineteen galleys, being shut out by the Milesians, lay at anchor at Lada, an island over against the city.

Presently upon the revolt of Miletus was made the first league between the king and the Lacedaemonians by Tissaphernes and Chalcideus, as followeth:

"The Lacedaemonians and their confederates have made a league with the king and Tissaphernes on these articles: "Whatsoever territory or cities the king possesseth and his ancestors have possessed, the same are to remain the king's. "Whatsoever money or other profit redounded to the Athenians from their cities, the king and the Lacedaemonians are jointly to hinder, so as the Athenians may receive nothing from thence, neither money nor other thing.
