History of the Peloponnesian War

The Athenians, however, if anything, had rather the advantage, and on the departure of the Corinthians set up a trophy. Urged by the taunts of the elders in their city, the Corinthians made their preparations, and about twelve days afterwards came and set up their trophy as victors. Sallying out from Megara, the Athenians cut off the party that was employed in erecting the trophy, and engaged and defeated the rest.

In the retreat of the vanquished army, a considerable division, pressed by the pursuers and mistaking the road, dashed into a field on some private property, with a deep trench all round it, and no way out.

Being acquainted with the place, the Athenians hemmed their front with heavy infantry, and placing the light troops round in a circle, stoned all who had gone in. Corinth here suffered a severe blow. The bulk of her army continued its retreat home.

About this time the Athenians began to build the long walls to the sea, that towards Phalerum and that towards Piraeus.

Meanwhile the Phocians made an expedition against Doris, the old home of the Lacedaemonians, containing the towns of Boeum, Kitinium, and Erineum. They had taken one of these towns, when the Lacedaemonians under Nicomedes, son of Cleombrotus, commanding for King Pleistoanax, son of Pausanias, who was still a minor, came to the aid of the Dorians with fifteen hundred heavy infantry of their own, and ten thousand of their allies. After compelling the Phocians to restore the town on conditions, they began their retreat.
