History of the Peloponnesian War

From the ditch the Plataeans in troop took the way towards Thebes, leaving on the left hand the temple of Juno built by Androcrates, both for that they supposed they would least suspect the way that led to their enemies, and also because they saw the Peloponnesians with their lights pursue that way, which by Mount Cithaeron and the Oak-heads led to Athens.

The Plataeans, when they had gone six or seven furlongs, forsook the Theban way and turned into that which led towards the mountain to Erythrae and Hysiae and, having gotten the hills, escaped through to Athens, being two hundred and twelve persons of a greater number. For some of them returned into the city before the rest went over, and one of their archers was taken upon the ditch without. And so the Peloponnesians gave over the pursuit and returned to their places.

But the Plataeans that were within the city, knowing nothing of the event and those that turned back having told them that not a man escaped, as soon as it was day sent a herald to entreat a truce for the taking up of their dead bodies; but when they knew the truth, they gave it over. And thus these men of Plataea passed through the fortification of their enemies and were saved.
