History of the Peloponnesian War

The vanquished party now retreated, and a not inconsiderable portion of them, being hard pressed, missed their way and rushed into a piece of land belonging to some private person, which was enclosed by a great ditch and had no exit.

And when the Athenians perceived this, they shut them in by barring the entrance with hoplites, and stationing light-armed troops all round stoned all who had entered. And this was a great calamity to the Corinthians; the main body of their army, however, returned home.
