History of the Peloponnesian War

The next day the Athenians advanced, and the horse and dart-men of the Syracusans and allies, each in great numbers, impeded their progress, hurling their missiles upon them, and annoying them with cavalry charges. The Athenians fought for a long time, and then returned again to the same camp, no longer having provisions as they had before; for it was no more possible to leave their position, because of the cavalry.

Having started early, they began their march again, and forced their way to the hill which had been fortified; where they found before them the enemy's infantry drawn up for the defence of the wall many spears deep; for the pass was but narrow.
