History of the Peloponnesian War

He has represented it as consisting of twelve hundred vessels; the Boeotian complement of each ship being a hundred and twenty men, that of the ships of Philoctetes fifty. By this, I conceive, he meant to convey the maximum and the minimum complement: at any rate he does not specify the amount of any others in his catalogue of the ships. That they were all rowers as well as warriors we see from his account of the ships of Philoctetes, in which all the men at the oar are bowmen. Now it is improbable that many supernumeraries sailed if we except the kings and high officers; especially as they had to cross the open sea with munitions of war, in ships, moreover, that had no decks, but were equipped in the old piratical fashion.

So that if we strike the average of the largest and smallest ships, the number of those who sailed will appear inconsiderable, representing, as they did, the whole force of Hellas.
