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.

At the close of the same winter, Salaethus the Lacedaemonian was sent out from Lacedaemon in a trireme to Mytilene; and having gone by sea to Pyrrha, and thence by land, he entered Mytilene unobserved, along the bed of a torrent, where the lines round the town were passable, and told the magistrates that there would be an invasion of Attica, and at the same time the ships would come which were to have assisted them before; and that he himself had been despatched in advance on this account, and to attend to all other matters.

The Mytilenaeans therefore took fresh courage, and thought less of coming to terms with the Athenians. And so ended this winter, and the fourth year of the war of which Thucydides wrote the history.
