History of the Peloponnesian War

The states in Sicily, therefore, from all that I can hear, will be found as I say, and I have not pointed out all our advantages, for we shall have the help of many barbarians, who from their hatred of the Syracusans will join us in attacking them; nor will the powers at home prove any hindrance, if you judge rightly.

Our fathers with these very adversaries, which it is said we shall now leave behind us when we sail, and the Mede as their enemy as well, were able to win the empire, depending solely on their superiority at sea.

The Peloponnesians had never so little hope against us at present; and let them be ever so sanguine, although strong enough to invade our country even if we stay at home, they can never hurt us with their navy, as we leave one of our own behind us that is a match for them.

In this state of things what reason can we give to ourselves for holding back, or what excuse can we offer to our allies in Sicily for not helping them? They are our confederates, and we are bound to assist them, without objecting that they have not assisted us. We did not take them into alliance to have them to help us in Hellas, but that they might so annoy our enemies in Sicily as to prevent them from coming over here and attacking us.
