When, however, the Peloponnesians had sailed away and their army on land had dispersed, the Athenians also set up a trophy in token of victory, in Achaea at a distance of about twenty stadia from Erineus, where the Corinthians were formerly stationed. And so the sea-fight ended.
Demosthenes and Eurymedon,[*](cf. 7.33.6.) when the Thurians had been induced to join in the campaign with them with seven hundred hoplites and three hundred javelin-men, gave orders that the ships should sail along the coast toward the territory of Croton, while they themselves, after first reviewing all their land forces at the river Sybaris, advanced through the territory of Thuria.
And when they came to the river Hylias and the Crotoniates sent word to them that their army could not go through their territory with their consent, they went down and bivouacked near the sea at the mouth of the Hylias; and their ships met them at that point. On the next day they embarked their army and proceeded along the coast, touching at the various cities, with the exception of Locri, until they reached Petra in the territory of Rhegium.
The Syracusans, meanwhile, hearing of their approach, wished to make another trial with their fleet, and also with their land-force, which they had been collecting for the very purpose of striking a blow before the Athenian reinforcements came.
They had prepared the fleet generally in such a way as, after the experience of the former sea-fight, seemed likely to offer some advantage, and in particular had shortened the prows of the ships, and had made them stouter by attaching to them thick catheads and stretching underneath stay-beams extending from them to the ships' sides for the length of six cubits both inside and outside the vessel, adopting the same plan as that followed by the Corinthians when they reconstructed their ships at the prows for the battle fought against the Athenian fleet at Naupactus.
