History of the Peloponnesian War

Nicias, then, delivered this exhortation, and at the same time went up to the troops, and if he saw them any where straggling, and not marching in order, he collected and brought them to their post; while Demosthenes also did no less to those who were near him, addressing them in a similar manner.

They marched in the form of a hollow square, the division under Nicias taking the lead, and that of Demosthenes following;

while the baggage bearers and the main crowd of camp followers were enclosed within the heavy-armed. When they had come to the ford of the river Anapus, they found drawn up at it a body of the Syracusans and allies; but having routed these, and secured the passage, they proceeded onwards; while the Syracusans pressed them with charges of horse, as their light-armed did with their missiles.

On that day the Athenians advanced about forty stades, and then halted for the night on a hill. The day following, they commenced their march at an early hour, and having advanced about twenty stades, descended into a level district, and there encamped, wishing to procure some eatables from the houses, (for the place was inhabited,) and to carry on with them water from it, since for many stades before them, in the direction they were to go, it was not plentiful.

The Syracusans, in the mean time, had gone on before, and were blocking up the pass in advance of them. For there was there a steep hill, with a precipitous ravine on either side of it, called the Acraeum Lepas.

The next day the Athenians advanced, and the horse and dart-men of the Syracusans and allies, each in great numbers, impeded their progress, hurling their missiles upon them, and annoying them with cavalry charges. The Athenians fought for a long time, and then returned again to the same camp, no longer having provisions as they had before; for it was no more possible to leave their position, because of the cavalry.
