History of the Peloponnesian War

Not discovered until their voyage was nearly completed, they arrived a little before Strombichides and Thrasycles (who had just come with twelve ships from Athens, and had joined Strombichides in pursuing them), and occasioned the revolt of Miletus. The Athenians sailing up close on their heels with nineteen ships found Miletus closed against them, and took up their station at the adjacent island of Lade.

The first alliance between the king and the Lacedaemonians was now concluded immediately upon the revolt of the Milesians, by Tissaphernes and Chalcideus, and was as follows:—

The Lacedaemonians and their allies made a treaty with the king and Tissaphernes upon the terms following:—1. Whatever country or cities the king has, or the king's ancestors had, shall be the king's; and whatever came in to the Athenians from these cities, either money or any other thing, the king and the Lacedaemonians and their allies shall jointly hinder the Athenians from receiving either money or any other thing.
