History of the Peloponnesian War

After this the Athenians weighed from Corcyra, and proceeded to cross to Sicily with an armament now consisting of one hundred and thirty-four galleys in all (besides two Rhodian fifty-oars) of which one hundred were Athenian vessels—sixty men-of-war, and forty troopships—and the remainder from Chios and the other allies; five thousand and one hundred heavy infantry in all, that is to say, fifteen hundred Athenian citizens from the rolls at Athens and seven hundred Thetes shipped as marines, and the rest allied troops, some of them Athenian subjects, and besides these five hundred Argives, and two hundred and fifty Mantineans serving for hire; four hundred and eighty archers in all, eighty of whom were Cretans, seven hundred slingers from Rhodes, one hundred and twenty light-armed exiles from Megara, and one horse-transport carrying thirty horses.

Such was the strength of the first armament that sailed over for the war. The supplies for this force were carried by thirty ships of burden laden with corn, which conveyed the bakers, stone-masons and carpenters, and the tools for raising fortifications, accompanied by one hundred boats, like the former pressed into the service, besides many other boats and ships of burden which followed the armament voluntarily for purposes of trade; all of which now left Corcyra and struck across the Ionian sea together.
