Clearly there was nothing to be gained by further discussion, and Clearchus said, ‘You have spoken, but take to the King this answer, that if he desires our service as friends, it is better for him that we should keep our arms. And on the other hand, if he regards us as enemies, it is better for us that we should have them.’ With this message, the ambassadors returned to the King. When they were gone, Clearchus announced to the other generals that the omens of the sacrifice which he had just caused to be offered, were unfavourable for a battle with the King, but favourable for the proposal to join forces with Ariæus. Soon afterwards the messengers returned from Ariæus with the answer that he did not care to accept the offer of the Hellenes to set him on the throne, because among the great lords of Persia there were many more powerful and distinguished than himself, who would never endure to see him placed above them. But he said that early the next morning he was going to begin the return-march to Sardis, and that the Hellenes might go with him if they liked. The generals decided to do so, and although it was already dark, they set out at once for the place where he was encamped, and reached it about midnight. There they entered into a treaty with Ariæus, and confirmed it with sacred rites in order that it might be doubly sure. According to the Persian custom, a bull, a wolf, a wild boar, and a ram were slaughtered, and their blood was mingled in the hollow of a shield, into which the Hellene officers dipped their swords and the Barbarian officers their lances. Then they swore on both sides to help one another in every difficulty. Neither party was to desert the other, the Barbarians were to act as guides to the Hellenes, according to the best of their knowledge, and in all emergencies they were to stand by one another as true friends. XVIII THE TREATY WITH THE GREAT KING The next thing was to decide as to the best route for the return march, and Ariæus was of opinion that it would be better not to return by the way they had come. ‘If we go that way’ he said, ‘we cannot fail to perish from hunger, for even on the journey hither we have often been short of food, and in those places where food was plentiful, we have already taken all that was to be had. I think I can show you a better way, which though longer, goes through fruitful districts. But for the first few days we must make long forced marches, so as to get at least two or three days’ journey in advance of the Great King. He will give up the idea of pursuing us, for he would not venture to come after us with a small army; and with a great army, which must of necessity move slowly, he would not be able to overtake us.’
