History of the Peloponnesian War

Meanwhile those who had at first fled for refuge to the city, seeing the turn affairs were taking, now rallied from the town and formed against the Athenians in front of them, sending also a part of their number to the Circle on Epipolae, which they hoped to take while denuded of its defenders.

These took and destroyed the Athenian outwork of a thousand feet, the Circle itself being saved by Nicias, who happened to have been left in it through illness, and who now ordered the servants to set fire to the engines and timber thrown down before the wall; want of men, as he was aware, rendering all other means of escape impossible.

This step was justified by the result, the Syracusans not coming any further on account of the fire, but retreating. Meanwhile succors were coming up from the Athenians below, who had put to flight the troops opposed to them; and the fleet also, according to orders, was sailing from Thapsus into the great harbour.

Seeing this, the troops on the heights retired in haste, and the whole army of the Syracusans re-entered the city, thinking that with their present force they would no longer be able to hinder the wall reaching the sea.
