History of the Peloponnesian War

When it was told Hippocrates, who was then at Delium, that the Boeotians were marching after them, he sends presently to the army, commanding them to be put in array. And not long after he came himself, having left some three hundred horse about Delium, both for a guard to the place if it should be assaulted, and withal to watch an opportunity to come upon the Boeotians when they were in fight.

But for these, the Boeotians appointed some forces purposely to attend them. And when all was as it should be, they showed themselves from the top of the hill, where they sat down with their arms in the same order they were to fight in, being about seven thousand men of arms, of light-armed soldiers above ten thousand, a thousand horsemen, and five hundred targetiers.
