The Eight Books of Thucydides' History, translated by R. Crawley.
Seventh and Eighth Years of the War—End of Corcyraean Revolution— Peace of Gela—Capture of Nisaea
The same summer, directly after these events, the Athenians made an expedition against the territory of Corinth with eighty ships and two thousand Athenian heavy infantry, and two hundred cavalry on board horse transports, accompanied by the Milesians, Andrians, and Carystians from the allies, under the command of Nicias, son of Niceratus, with two colleagues. Putting out to sea they made land at daybreak between Chersonese and Rheitus, at the beach of the country underneath the Solygian hill, upon which the Dorians in old times established themselves and carried on war against the Aeolian inhabitants of Corinth, and where a village now stands called Solygia. The beach where the fleet came to is about a mile and a half from the village, seven miles from Corinth, and two and a quarter from the Isthmus. The Corinthians had heard from Argos of the coming of the Athenian armament, and had all come up to the Isthmus long before, with the exception of those who lived beyond it, and also of five hundred who were away in garrison in Ambracia and Leucadia; and they were there in full force watching for the Athenians to land. These last, however, gave them the slip by coming in the dark; and being informed by signals of the fact the Corinthians left half their number at Cenchreae, in case the Athenians should go against Crommyon, and marched in all haste to the rescue.
