History of the Peloponnesian War

Now of former achievements, the greatest that was performed was the Median; and yet that had its decision quickly, in two battles by sea and two by land. But of this war both the duration was very long, and sufferings befell Greece in the course of it, such as were never matched in the same time.

For neither were so many cities ever taken and laid desolate, some by barbarians, and some by the parties themselves opposed in the war; (some, too, changed their inhabitants when taken;) nor was there so much banishing of men and bloodshed, partly in the war itself, and partly through sedition.
