History of the Peloponnesian War

The conquered forces commenced a retreat;

and a considerable division of them, being hard pressed and having missed their way, rushed into a field belonging to a private person, which had a deep trench enclosing it, and there was no road out. the Athenians, perceiving this, hemmed them in with heavy-armed in front, and having placed their light armed all round, stoned to death all who had gone in; and this was a severe blow for the Corinthians. The main body of their army returned home.

About this time the Athenians began also to build their long walls down to the sea, both that to Phalerus, and that to Piraeus.

And the Phocians having marched against the Dorians, the mother-country of the Lacedaemonians, [whose towns were] Boeum, and Citinium, and Erineum, and having taken one of these places, the Lacedaemonians under the command of Nicomedes, the son of Cleombrotus, in the stead of Pleistoanax, son of Pausanias, who was yet a minor, went to the aid of the Dorians with fifteen hundred heavy-armed of their own, and ten thousand of the allies; and having compelled the Phocians to restore the town on certain conditions, they proceeded to return back.
