History of the Peloponnesian War

In the mean time, as the march they had to make was a long one, the Athenians quietly pitched their camp in a favourable position, where they would be able to commence an engagement just when they pleased, and the Syracusan horse would cause them the least annoyance, both during the action and before it. For on one side they were flanked by walls, houses, trees, and a marsh; on the other, by cliffs.

They also felled the trees near to them, and carrying them down to the sea, fixed a palisade by their ships; while with rude stones and wood they hastily erected a fort at Dasoon, where their position was most open to the enemy's attack, and broke down the bridge over the Anapus.

While they were making these preparations, no one came out from the city to stop them; but the Syracusan cavalry was what first came against them, and afterwards all the infantry was mustered. And at first they advanced near the camp of the Athenians; then, when they did not go out against them, they withdrew, and crossed the road to Helorus, and there encamped for the night.

The next day the Athenians and their allies prepared for battle, and made their dispositions as follows. The right wing was held by the Argives and Mantineans, the centre by the Athenians, and the remainder of the line by the rest of the allies. Half of their force was posted in advance, drawn up eight deep; the other half, close upon their tents, in a hollow square, which was also formed eight deep, with orders to look out where any part of the army might be most distressed, and go to its support. Within this body of reserve, too, they placed the camp-followers.
