History of the Peloponnesian War

Now the Athenians were by this time in much disorder and perplexity; but on this subject it was not easy for me to ascertain from either side, in what way each event occurred. For in the day-time the parties engaged have, indeed, a clearer knowledge, though not a perfect one even then, for each man barely knows what happens in his own part of the field. But in a night engagement, (and this was the only one which occurred between great armies during this war,) how could any one have a distinct knowledge of any thing?

For though there was a bright moon, they only saw one another (as was natural they should by moonlight) so as to discern the form of the body before them, but to mistrust their knowledge of its being that of a friend. And there were no few heavy-armed on each side moving in a narrow space.
