Xenophon

“ But Clearchus had with him the Eleian Tolmides, the best herald of his time; him he ordered to proclaim silence, and then to give out this proclamation of the generals: "Whoever will give any information as to who let an ass into the camp shall receive a talent of silver in reward." On hearing this proclamation the soldiers made up their minds that their fear was baseless, and their generals safe and sound. At break of day Clearchus gave the order to the Hellenes to get under arms in line of battle, and take up exactly the same position as they held on the day of the battle. ”

“ There they exchanged oaths--the Hellenes on the one side and Ariaeus with his principal officers on the other--not to betray one another, but to be true to each other as allies. The Asiatics further solemnly pledged themselves by oath to lead the way without treachery. ”

“ The king will never overtake us. With a small army he will not dare to dog our heels, and with a vast equipment he will lack the power to march quickly. Perhaps he, too, may even find a scarcity of provisions. ”
