History of the Peloponnesian War

Against a power of this kind it will not do to have merely a weak naval armament, but we shall want also a large land army to sail with us, if we are to do anything worthy of our ambition, and are not to be shut out from the country by a numerous cavalry; especially if the cities should take alarm and combine, and we should be left without friends (except the Egestaeans) to furnish us with horse to defend ourselves with.

It would be disgraceful to have to retire under compulsion, or to send back for reinforcements, owing to want of reflection at first: we must therefore start from home with a competent force, seeing that we are going to sail far from our country, and upon an expedition not like any which you may have undertaken in the quality of allies, among your subject states here in Hellas, where any additional supplies needed were easily drawn from the friendly territory; but we are cutting ourselves off, and going to a land entirely strange, from which during four months in winter it is not even easy for a messenger to get to Athens.

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.

Indeed, even if we leave Athens with a force not only equal to that of the enemy except in the number of heavy infantry in the field, but even at all points superior to him, we shall still find it difficult to conquer Sicily or save ourselves.
