The king proposes a truce, and supplies the Greeks with provisions during the negotiation. Three days after he sends Tissaphernes to them, to ask why they had engaged in hostilities against him; he is answered by Clearchus. A treaty is then concluded, the king engaging to send home the Greeks under the conduct of Tissaphernes, and the Greeks promising to do no injury to the countries through which they should pass.The Greeks conceive distrust both of Tissaphernes and Ariæus, and resolve to march apart from the Persians. They commence their march under the guidance of Tissaphernes, pass the wall of Media, and cross the Tigris.CHAPTER IV.
