Furthermore, they resolved that when they had come to that place, which is encircled by the divided channels of Asopus' daughter Oeroe as she flows from Cithaeron, they would in that night send half of their army to Cithaeron, to remove their followers who had gone to get the provisions; for these were cut off from them on Cithaeron.
Having made this plan, all that day they suffered constant hardship from the cavalry which continually pressed upon them. When the day ended, however, and the horsemen stopped their onslaught, then at that hour of the night at which it was agreed that they should depart, most of them rose and departed, not with intent to go to the place upon which they had agreed. Instead of that, once they were on their way, they joyfully shook off the horsemen and escaped to the town of Plataea [23.2667,38.2] (Perseus) Plataea. In the course of their flight they came to the temple of Hera which is outside of that town, twenty furlongs distant from the Gargaphian spring and piled their arms in front of the temple.
