History of the Peloponnesian War

The Syracusans now thought the stockades and stonework of their counter-wall sufficiently far advanced; and as the Athenians, afraid of being divided and so fighting at a disadvantage, and intent upon their own wall, did not come out to interrupt them, they left one tribe to guard the new work and went back into the city. Meanwhile the Athenians destroyed their pipes of drinking-water carried underground into the city; and watching until the rest of the Syracusans were in their tents at midday, and some even gone away into the city, and those in the stockade keeping but indifferent guard, appointed three hundred picked men of their own, and some men picked from the light troops and armed for the purpose, to run suddenly as fast as they could to the counterwork, while the rest of the army advanced in two divisions, the one with one of the generals to the city in case of a sortie, the other with the other general to the stockade by the postern gate.

The three hundred attacked and took the stockade, abandoned by its garrison, who took refuge in the outworks round the statue of Apollo Temenites. Here the pursuers burst in with them, and after getting in were beaten out by the Syracusans, and some few of the Argives and Athenians slain;

after which the whole army retired, and having demolished the counterwork and pulled up the stockade, carried away the stakes to their own lines, and set up a trophy.

The next day the Athenians from the Circle proceeded to fortify the cliff above the marsh which on this side of Epipolae looks towards the great harbour; this being also the shortest line for their work to go down across the plain and the marsh to the harbour.

Meanwhile the Syracusans marched out and began a second stockade, starting from the city, across the middle of the marsh, digging a trench alongside to make it impossible for the Athenians to carry their wall down to the sea.

As soon as the Athenians had finished their work at the cliff they again attacked the stockade and ditch of the Syracusans. Ordering the fleet to sail round from Thapsus into the great harbour of Syracuse, they descended at about dawn from Epipolae into the plain, and laying doors and planks over the marsh where it was muddy and firmest, crossed over on these, and by daybreak took the ditch and the stockade, except a small portion which they captured afterwards.
