History of the Peloponnesian War

You, therefore, with whom alone we freely share our empire, we now justly require not to betray that empire in its extremity, and in scorn of Corinthians, whom you have often conquered, and of Siceliots, none of whom so much as presumed to stand against us when our navy was in its prime, we ask you to repel them, and to show that even in sickness and disaster your skill is more than a match for the fortune and vigor of any other.

For the Athenians among you I add once more this reflection:—you left behind you no more such ships in your docks as these, no more heavy infantry in their flower; if you do aught but conquer, our enemies here will immediately sail thither, and those that are left of us at Athens will become unable to repel their home assailants, reinforced by these new allies. Here you will fall at once into the hands of the Syracusans—I need not remind you of the intentions with which you attacked them—and your countrymen at home will fall into those of the Lacedaemonians.

Since the fate of both thus hangs upon this single battle—now, if ever, stand firm, and remember, each and all, that you who are now going on board are the army and navy of the Athenians, and all that is left of the state and the great name of Athens, in whose defence if any man has any advantage in skill or courage, now is the time for him to show it, and thus serve himself and save all.’
