During the same summer and directly after these events the Athenians made an expedition into Corinthian territory with eighty ships and two thousand Athenian hoplites, together with two hundred cavalry on board horse-transports; allied forces also went with them, namely Milesian, Andrian, and Carystian troops, the whole being under the command of Nicias son of Niceratus and two others.
These sailed and at day-break landed midway between the peninsula Chersonesus and the stream Rheitus, at a point on the beach over which rises the Solygeian hill-the hill where the Dorians in olden times[*](At the time when the Dorians, under the leadership of the Heracleidae, got possession of the Peloponnesus (cf. 1.12.3). See Busolt, Gr. Gesch. i. 208, ed. 2.) established themselves when they made war upon the Corinthians in the city, who were Aeolians; and there is still on the hill a village called Solygeia. From this point on the beach where the ships put in to shore this village is twelve stadia distant, the city of Corinth sixty, and the Isthmus twenty.
