History of the Peloponnesian War

As for the Athenians, when the enemy no longer came against them and offered battle, they stripped the corpses, took up their own dead, and straightway set up a trophy.

Meanwhile the other half of the Corinthian forces, which was stationed at Cenchraeae as a garrison to prevent the Athenians from making a descent upon Crommyon, were unable to see the battle because Mt. Oneium intervened; but when they saw the cloud of dust and realized what was going on, they rushed thither at once, as did also the older men in the city of Corinth when they perceived what had happened.
