94. At the very beginning of the following spring the Athenians quitted-Catana, and sailed¹ along the coast towards the Sicilian Megara; this place, as I have already² mentioned³, in the days of Gelo the tyrant was depopulated by the Syracusans, who still retain possession of the country. [2] They disembarked, and after ravaging the fields proceeded to attack a small Syracusan fortress⁴, but without success; they then moved on some by land and some by sea to the river Terias, and going up the country wasted the plain and burned the corn. They encountered a few Syracusans, some of whom they killed, and setting up a trophy returned to their ships. They then sailed back to Catana, and having taken in provisions marched with their whole force against Centoripa, a Sicel town, which capitulated. [3] Thence they returned, and on their way burned the corn of the Inessians and the Hyblaeans. [4] Arriving at Catana they found that the horsemen, for whom they had sent, to the number of two hundred and fifty had come from Athens, with their equipment, but without horses, which they were expected to procure on the spot. Thirty mounted archers and three hundred talents of silver⁵ had arrived also.
