History of the Peloponnesian War

When they had come up to the hill on the side of Euryelus, the same way that the former army also had in the first instance made the ascent, they escaped the observation of the Syracusan guard, and having gone to the fort of the Syracusans which was there, they took it, and put part of the garrison to the sword.

But the greater part fled immediately to the camps, (of which there were three on Epipolae, in outworks, one composed of the Syracusans, one of the other Siceliots, and one of their allies,) and informed them of the attack, and told it to the six hundred Syracusans who had formed the original guard at this part of Epipolae.

They immediately went against them; and Demosthenes and the Athenians falling in with them, routed them, though they made a spirited resistance. They then immediately pressed on, that they might not be retarded in their present eagerness for accomplishing the objects they had come for: while others of them proceeded, as their first measure, to take the counter-wall of the Syracusans, and pull down its battlements.

The Syracusans and their allies, as well as Gylippus and his division, went to the rescue from the outworks; and as they had had this daring attack made on them in the night, they engaged the Athenians in some dismay, and were at first compelled to retreat.
