"When Cyrus summoned me, I took you and set out, so that if he needed anything, I might assist him in return for the kindness I had received from him. But since you are not willing to continue the march, it is necessary for me either to betray you and rely on the friendship of Cyrus, or to deceive him and be with you. Whether I will act justly, I do not know. But I will choose you, and I will suffer whatever is necessary with you. No one will ever say that I led Greeks into the territory of the barbarians, betrayed the Greeks, and chose the friendship of the barbarians.

We are no longer his soldiers, since we are not following him, and he is no longer our paymaster. Yet, I know that he considers himself wronged by us, and so, even though he summons me..."
