In the meantime, they that fled at first to the city, seeing how things went, took heart again, and re-embattled themselves against the same Athenians that stood ranged against them before; and withal sent a certain portion of their army against the circular fortification of the Athenians upon Epipolae, supposing to find it without defendants and so to take it.
And they took and demolished the outworks ten plethers in length; but the circle itself was defended by Nicias, who chanced to be left within it for infirmity. For he commanded his servants to set fire on all the engines and whatsoever wooden matter lay before the wall:
knowing there was no other possible means to save themselves for want of men. And it fell out accordingly, for by reason of this fire they came no nearer, but retired. For the Athenians, having by this time beaten back the enemy below, were coming up to relieve the circle; and their galleys withal (as is before mentioned) were going about from Thapsus into the great haven.
Which they above perceiving, speedily made away, they and the whole army of the Syracusians, into the city, with opinion that they could no longer hinder them, with the strength they now had, from bringing their wall through unto the sea.
