History of the Peloponnesian War

As for the ambassadors who had gone at the time mentioned-after the taking of Plemyrium-from Syracuse to the cities, they had prevailed on them to join their side, and had raised and were just about to lead off the force, when Nicias, receiving early intelligence of it, sent to those of the Sicels who held the passes, and were in alliance with the Athenians, namely, the Centotripes, Alicyaeans, and some others, to beg them not to give free passage to the enemy, but to unite together and prevent their marching through their country, since there was no other by which they would attempt to do so, as the Acragantines would not grant them a passage through theirs.

When therefore the Siceliots were even on their march, the Sicels, in compliance with the request of the Athenians, laid an ambuscade for them in three different places, and falling upon them while off their guard and without any notice, killed about eight hundred of them, with all the ambassadors except one, namely, the Corinthian, who led to Syracuse those that had escaped, to the number of fifteen hundred.

About that same time the Camarinaeans also came to their help with five hundred heavy-armed, three hundred dartmen, and three hundred bow-men. The Geloans, too, sent a squadron of five ships, four hundred dart-men, and two hundred horse.

For by this time pretty nearly the whole of Sicily—excepting the Acragantines, who were neutral—the rest, I say, who before had waited to see the result of events, now united with the Syracusans, and assisted them against the Athenians.

The Syracusans, then, after the disaster in the Sicel country had befallen them, ceased for the present from attacking the Athenians. Demosthenes and Eurymedon, on the other hand, their forces being now ready both from Corcyra and the continent, crossed the Ionian gulf with all their army to the Iapygian foreland. Starting thence, they touched at the Choerades islands, lying off Iapygia, and took on board their ships some Iapygian dart-men, one hundred and fifty in number, of the Messapian tribe;

and after renewing an old friendship with Artas, who also had provided them with the dart-men, being one of their chieftains, they arrived at Metapontum in Italy. After persuading the Metapontines to send with them, on the strength of their alliance, three hundred dart-men and two triremes, with this addition to their armament they coasted along to Thuria.

There they found the opponents of the Athenians recently expelled in consequence of a sedition.

And as they wished to muster there the whole army, in case any part had been left behind, and to review it, as well as to persuade the Thurians to join them as zealously as possible in the expedition, and to have considering their present position, the same foes and friends as the Athenians, they waited awhile in Thuria, and were prosecuting these designs.
