So far, so good; and what besides? Ten fast-sailing war-galleys. Since Philip has a fleet, we must have fast vessels if our force is to sail in safety. Now how is this army to be maintained? That also I will explain fully, when I have told you why I think so small a force sufficient, and why I insist that those serving shall be citizens.
I name a force of this size, Athenians, because it is not in our power now to provide one fit to meet him in pitched battle: we must adopt guerilla tactics to start with. The force must therefore be neither unwieldy—for we cannot afford the pay and maintenance—nor altogether insignificant.
