History of the Peloponnesian War

Examine only how we acted after the departure of the Mede and the recovery of the constitution; when the Athenians attacked the rest of Hellas and endeavored to subjugate our country, of the greater part of which faction had already made them masters. Did not we fight and conquer at Coronea and liberate Boeotia, and do we not now actively contribute to the liberation of the rest, providing horses to the cause and a force unequalled by that of any other state in the confederacy?

Let this suffice to excuse us for our Medism. We will now endeavor to show that you have injured the Hellenes more than we, and are more deserving of condign punishment.
