History of the Peloponnesian War

I think, therefore, that we ought to take great numbers of heavy infantry, both from Athens and from our allies, and not merely from our subjects, but also any we may be able to get for love or for money in Peloponnese, and great numbers also of archers and slingers, to make head against the Sicilian horse. Meanwhile we must have an overwhelming superiority at sea, to enable us the more easily to carry in what we want; and we must take our own corn in merchant vessels, that is to say, wheat and parched barley, and bakers from the mills compelled to serve for pay in the proper proportion; in order that in case of our being weather-bound the armament may not want provisions, as it is not every city that will be able to entertain numbers like ours. We must also provide ourselves with everything else as far as we can, so as not to be dependent upon others; and above all we must take with us from home as much money as possible, as the sums talked of as ready at Egesta are readier, you may be sure, in talk than in any other way.
