History of the Peloponnesian War

Such was the amount of the first armament which sailed over for the war. For these troops thirty ships of burden, laden with corn, carried provisions, with the bakers, stone-masons, carpenters, and all the tools for building fortifications; and also one hundred boats, which, together with the ships of burden, were pressed into the service; while many other boats and ships of burden followed the armament voluntarily, for purposes of commerce; all of which proceeded at that time to cross the Ionian Gulf from Corcyra.
