History of the Peloponnesian War

Starting from the ditch, the Plataeans went all together along the road leading to Thebes, keeping the chapel of the hero Androcrates upon their right; considering that the last road which the Peloponnesians would suspect them of having taken would be that towards their enemies' country. Indeed they could see them pursuing with torches upon the Athens road towards Cithaeron and Druoskephalai or Oakheads.

After going for rather more than half a mile upon the road to Thebes, the Plataeans turned off and took that leading to the mountain, to Erythrae and Hysiae, and reaching the hills, made good their escape to Athens, two hundred and twelve men in all; some of their number having turned back into the town before getting over the wall, and one archer having been taken prisoner at the outer ditch.

Meanwhile the Peloponnesians gave up the pursuit and returned to their posts; and the Plataeans in the town, knowing nothing of what had passed, and informed by those who had turned back that not a man had escaped, sent out a herald as soon as it was day to make a truce for the recovery of the dead bodies, and then learning the truth, desisted. In this way the Plataean party got over and were saved.

Towards the close of the same winter, Salaethus, a Lacedaemonian, was sent out in a trireme from Lacedaemon to Mitylene. Going by sea to Pyrrha, and from thence overland, he passed along the bed of a torrent, where the line of circumvallation was passable, and thus entering unperceived into Mitylene, told the magistrates that Attica would certainly be invaded, and the forty ships destined to relieve them arrive, and that he had been sent on to announce this and to superintend matters generally.

The Mitylenians upon this took courage, and laid aside the idea of treating with the Athenians; and now this winter ended, and with it ended the fourth year of the war of which Thucydides was the historian.
