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.
