History of the Peloponnesian War

While the Athenians lingered on in this way without moving from where they were, Gylippus and Sicanus now arrived at Syracuse. Sicanus had failed to gain Agrigentum, the party friendly to the Syracusans having been driven out while he was still at Gela; but Gylippus was accompanied not only by a large number of troops raised in Sicily, but by the heavy infantry sent off in the spring from Peloponnese in the merchantmen, who had arrived at Selinus from Libya.

They had been carried to Libya by a storm, and having obtained two galleys and pilots from the Cyrenians, on their voyage along shore had taken sides with the Euesperitae and had defeated the Libyans who were besieging them, and from thence coasting on to Neapolis, a Carthaginian mart, and the nearest point to Sicily, from which it is only two days' and a night's voyage, there crossed over and came to Selinus.
