18. "If, again, any of you are disheartened because we have no cavalry, and the enemy have a great number, consider that ten thousand cavalry are nothing more than ten thousand men; for no one ever perished in battle of being bitten or kicked by a horse; it is the men that do whatever is done in the encounter. 19. Doubtless we, too, rest upon a surer support than cavalry have, for they are raised upon horses, and are afraid, not only of us, but also of falling, while we, taking our steps upon the ground, shall strike such as approach us with far greater force, and hit much more surely the mark at which we may aim. In one point alone, indeed, have the cavalry the advantage, that it is safer for them to flee than for us. 20. "But if, though you have courage for battle, you are disquieted at the thought that Tissaphernes will no longer guide you, and that the king will no longer supply you with provisions, consider whether it is better to have Tissaphernes for our guide, who is manifestly plotting our destruction, or such persons as we ourselves may seize and compel to be our guides, who will be conscious that if they go wrong with regard to us, they go wrong with regard to their own lives and persons. 21. And as to provisions, whether is it better for us to purchase, in the markets which they provide, small measures of food for large sums of money, (no longer, indeed, having the money,) or, if we are successful in the field, to take supplies for ourselves, adopting whatever measure each of us may wish to use?
