History of the Peloponnesian War

Indeed, if you would know the plain truth, as we are credibly informed, the excess of their sufferings and the necessities of their present distress have made them desperate; they have no confidence in their force, but wish to try their fortune in the only way they can, and either to force their passage and sail out, or after this to retreat by land, it being impossible for them to be worse off than they are.

The fortune of our greatest enemies having thus betrayed itself, and their disorder being what I have described, let us engage in anger, convinced that, as between adversaries, nothing is more legitimate than to claim to sate the whole wrath of one's soul in punishing the aggressor, and nothing more sweet, as the proverb has it, than the vengeance upon an enemy, which it will now be ours to take.

That enemies they are and mortal enemies you all know, since they came here to enslave our country, and if successful had in reserve for our men all that is most dreadful, and for our children and wives all that is most dishonorable, and for the whole city the name which conveys the greatest reproach.
