History of the Peloponnesian War

The history of this period has been also written by the same Thucydides, an Athenian, in the chronological order of events by summers and winters, to the time when the Lacedaemonians and their allies put an end to the Athenian empire, and took the Long Walls and Piraeus. The war had then lasted for twenty-seven years in all.

Only a mistaken judgment can object to including the interval of treaty in the war. Looked at by the light of facts it cannot, it will be found, be rationally considered a state of peace, where neither party either gave or got back all that they had agreed, apart from the violations of it which occurred on both sides in the Mantinean and Epidaurian wars and other instances, and the fact that the allies in the direction of Thrace were in as open hostility as ever, while the Boeotians had only a truce renewed every ten days.

So that the first ten years' war, the treacherous armistice that followed it, and the subsequent war will, calculating by the seasons, be found to make up the number of years which I have mentioned, with the difference of a few days, and to afford an instance of faith in oracles being for once justified by the event.
