History of the Peloponnesian War

So after they had gone six or seven stades along the road to Thebes, they then turned off, and took that which leads to the mountain, to Erythrae, and Hysiae; and having reached the hills, they escaped to Athens, to the number of two hundred and twelve out of one originally greater; for some of them turned back again into the city before they passed over the wall, and one bowman was taken prisoner at the outer ditch. So the Peloponnesians gave up the pursuit and returned to their posts;

while the Plataeans in the town, knowing nothing of what had happened, but having been informed by those who returned that not a man had escaped, sent out a herald as soon as it was day, and wished to make a truce for taking up their dead; when, however, they knew the truth, they ceased from their application. In this way then the party of Plataeans passed over the wall and were saved.
