History of the Peloponnesian War

A small body of troops was also promised them by the Geloans and some of the Sicels, who were now ready to join them with far greater alacrity, both because of the recent death of Archonidas, who, being king of certain Sicel tribes of that region and a man of influence, had been a friend of the Athenians, and also because Gylippus had apparently come from Lacedaemon full of zeal.

So Gylippus, taking of his own seamen and of the marines those that were equipped with arms, about seven hundred, of Himeraean hoplites and light-armed troops together one thousand and one hundred cavalry, of the Selinuntians some light-armed troops and cavalry, a few Geloans, and of the Sicels about one thousand in all, advanced against Syracuse.

Meanwhile the Corinthians had put to sea from Leucas with the rest of their ships and were bringing aid as fast as they could; indeed, Gongylus, one of the Corinthian commanders, though he had set out last with a single ship, was the first to arrive at Syracuse, being a little ahead of Gylippus. Finding the Syracusans on the point of holding an assembly to discuss the abandonment of the war, he prevented the meeting and encouraged them, saying that not only were still other ships about to arrive, but also Gylippus son of Cleandridas, who had been sent by the Lacedaemonians to assume the command.
