Meanwhile the Athenians, undisturbed, as the Syracusans had a long way to go, settled their army in a suitable position, where they could begin a battle whenever they wished and the Syracusan horsemen would annoy them the least either in the actual fighting or before; for on one side walls and houses and trees and a swamp furnished a barrier, on the other side a line of cliffs.

They also cut down the trees near at hand and bringing them down to the sea built a stockade by the ships; and at Dascon, where the place was most accessible to the enemy, they quickly erected a bulwark of stones picked up in the fields and of timbers, and pulled down the bridge over the Anapus.

While they were making these preparations nobody came out from the city to hinder them; the first that came against them were the horsemen of the Syracusans, but afterwards the infantry also gathered in full force. And at first they drew near the Athenian camp, but later, when these did not come out against them, they withdrew across the Elorine road and spent the night.
