After this the two generals who were left in Sicily, making two divisions of the army and each taking one by lot, sailed with the whole force for Selinus and Egesta, wishing to know whether the Egestaeans would give the promised money, and to look into the affairs of the Selinuntians and learn their points of contention with the Egestaeans.
So sailing along the coast, with Sicily-that is, the part of it which faces the Tyrrhenian gulf-on their left hand, they put into Himera, which is the only Hellenic city in that part of Sicily; and as Himera would not receive them, they proceeded along the coast.
On their passage they took Hyccara, a petty town by the seaside, which, though Sicanian, was yet hostile to the Egestaeans. They enslaved the inhabitants, and turned the town over to the Egestaeans, some of whose cavalry had joined them, but themselves went back with their land-force through the territory of the Sicels until they came to Catana, while the ships sailed round to Catana with the captives.
Nicias, however, had sailed at once[*](ie. without waiting for Hyccara to be reduced and its inhabitants disposed of.) from Hyccara for Egesta, and after transacting his other business and receiving thirty talents had rejoined the army. Their slaves they sold, receiving for them one hundred and twenty talents.
They sent round also to their allies among the Sicels, bidding them send troops; and with half of their own force went against Hybla Geleatis, a hostile town, but failed to take it. And so the summer ended.
The following winter the Athenians began at once to prepare for the advance upon Syracuse, and the Syracusans also, on their side, to go against them.
For when the Athenians did not, in accordance with their first alarm and expectation, at once attack them, with each successive day their courage revived; and when the Athenians sailed along the opposite coast of Sicily and showed themselves only at a distance from Syracuse, and going against Hybla failed in the attempt to take it by storm, the Syracusans had still greater contempt for them, and, as a crowd is wont to do when it has become elated, demanded that their generals should lead them against Catana, since the Athenians would not come against them.
