History of the Peloponnesian War

As by day it seemed impossible to approach and get up without being observed, he ordered provisions for five days, took all the masons and carpenters, and other things, such as arrows, and everything else that they could want for the work of fortification if successful; and after the first watch set out with Eurymedon and Menander and the whole army for Epipolae, Nicias being left behind in the lines.

Having come up by the hill of Euryelus (where the former army had ascended at first), unobserved by the enemy's guards, they went up to the fort which the Syracusans had there, and took it, and put to the sword part of the garrison.

The greater number, however, escaped at once and gave the alarm to the camps, of which there were three upon Epipolae, defended by outworks, one of the Syracusans, one of the other Siceliots, and one of the allies; and also to the six hundred Syracusans forming the original garrison for this part of Epipolae.
