History of the Peloponnesian War

The ambassadors of the Syracusians, which after the taking of Plemmyrium had been sent unto the cities about, having now obtained and levied an army amongst them, were conducting the same to Syracuse. But Nicias, upon intelligence thereof, sent unto such cities of the Siculi as had the passages and were their confederates, the Centoripines, Halicyaeans, and others, not to suffer the enemy to go by, but to unite themselves and stop them, for that they would not so much as offer to pass any other way, seeing the Agrigentines had already denied them.

When the Sicilians were marching, the Siculi, as the Athenians had desired them, put themselves in ambush in three several places, and setting upon them unawares and on a sudden, slew about eight hundred of them, and all the ambassadors save only one, a Corinthian, which conducted the rest that escaped, being about fifteen hundred, to Syracuse.

About the same time came unto them also the aid of the Camarinaeans, five hundred men of arms, three hundred darters, and three hundred archers. Also the Geloans sent them men for five galleys, besides four hundred darters and two hundred horsemen.

For now all Sicily, except the Agrigentines, who were neutral, but all the rest, who before stood looking on, came in to the Syracusian side against the Athenians.

[Nevertheless], the Syracusians, after this blow received amongst the Siculi, held their hands and assaulted not the Athenians for a while. Demosthenes and Eurymedon, having their army now ready, crossed over from Corcyra and the continent with the whole army to the promontory of Iapygia. From thence they went to the Choerades, islands of Iapygia, and here took in certain Iapygian darters to the number of two hundred and fifty, of the Messapian nation.

And having renewed a certain ancient alliance with Artas, who reigned there and granted them those darters, they went thence to Metapontum, a city of Italy. There, by virtue of a league, they got two galleys and three hundred darters, which taken aboard, they kept along the shore till they came to the territory of Thurii.
