History of the Peloponnesian War

"That when the king's navy shall be come, the Lacedaemonians and their confederates shall maintain their own navy themselves, if they please; or if they will have Tissaphernes to maintain it, he shall do it; and that the Lacedaemonians and their confederates, at the end of the war, repay Tissaphernes whatsoever money they shall have received of him.

When the king's galleys shall be arrived, both they and the galleys of the Lacedaemonians and their confederates shall make the war jointly, according as to Tissaphernes and the Lacedaemonians and their confederates shall seem good; and if they will give over the war against the Athenians, they shall give it over in the same manner.

Such were the articles. After this Tissaphernes prepared for the fetching in of the Phoenician fleet, according to the agreement, and to do whatsoever else he had undertaken, desiring to have it seen, at least, that he went about it.

In the end of this winter, the Boeotians took Oropus by treason. It had in it a garrison of Athenians. They that plotted it were certain Eretrians and some of Oropus itself, who were then contriving the revolt of Euboea. For the place being built to keep Eretria in subjection, it was impossible, as long as the Athenians held it, but that it would much annoy both Eretria and the rest of Euboea.
