History of the Peloponnesian War

The Athenians, finding that they no longer advanced to engage them, spoiled the dead, and took up their own, and immediately erected a trophy.

But to that half of the Corinthians which had been posted at Cenchreae for protection, lest the enemy should sail against Crommyon, the battle was not visible, owing to [an intervening ridge of] Mount Oneum; but when they saw dust, and were aware of it, they immediately went to the scene of action; as also did the older Corinthians from the city, when they found what had been done.
