That Tissaphernes shall provide the pay for the ships now present. according to the contract, until the king's fleet has come;
but that when the king's fleet has come, the Lacedaemonians and their allies shall be at liberty to maintain their own ships, if they wish it. That if, however, they consent to receive supplies from Tissaphernes, he shall furnish them, and the Lacedaemonians and their allies shall refund to him, at the conclusion of the war, whatever sums of money they may have received.—
That after the king's ships have arrived, those of the Lacedaemonians and their allies and those of the king shall jointly carry on the war, according as Tissaphernes and the Lacedaemonians and their allies may think fit. And if they wish to terminate hostilities with the Athenians, they shall be terminated on the same footing.
This was the treaty that was made. And after this, Tissaphernes prepared to bring up the Phoenician fleet, as had been agreed, and all other things which he had promised; or, at any rate, he wished to appear to be thus preparing.
When the winter was now closing, the Boeotians took Oropus by treachery, while an Athenian garrison was holding it. There co-operated with them, also, some of the Eretrians and of the Oropians themselves, who were plotting the revolt of Euboea. For as the place was just opposite to Eretria, so long as the Athenians held it, it could not fail to do much damage both to Eretria and the rest of Euboea.
