History of the Peloponnesian War

Now so long as their bowmen had arrows and were able to use them the Athenians held out, for the Aetolian troops were light-armed and so, while they were exposed to the arrows, they were constantly driven back. But when the captain of the archers had been killed and his men scattered, and the hoplites were worn out, since they had been engaged for a long time in the unremitting struggle and the Aetolians were pressing them hard and hurling javelins upon them, they at last turned and fled, and falling into ravines from which there was no way out and into places with which they were unacquainted, they perished;

for Chromon, the Messenian, who had been their guide on the way, had unfortunately been killed. The Aetolians kept plying their javelins, and being swift of foot and lightly equipped, following at their heels they caught many there in the rout and slew them; but the greater number missed the roads and got into the forest, from which there were no paths out, and the Aetolians brought fire and set the woods ablaze around them.

Then every manner of flight was essayed and every manner of destruction befell the army of the Athenians, and it was only with difficulty that the survivors escaped to the sea at Oeneon in Locris, whence they had set out.
