History of the Peloponnesian War

The Syracusans meanwhile went on and fortified the pass in front, where there was a steep hill with a rocky ravine on each side of it, called the Acraean cliff.

The next day the Athenians advancing found themselves impeded by the missiles and charges of the horse and darters, both very numerous, of the Syracusans and allies; and after fighting for a long while, at length retired to the same camp, where they had no longer provisions as before, it being impossible to leave their position by reason of the cavalry.

Early next morning they started afresh and forced their way to the hill, which had been fortified, where they found before them the enemy's infantry drawn up many shields deep to defend the fortification, the pass being narrow.

The Athenians assaulted the work, but were greeted by a storm of missiles from the hill, which told with the greater effect through its being a steep one, and unable to force the passage, retreated again and rested.
