History of the Peloponnesian War

Whereupon the Athenians also, as the enemy came towards them, began to embark, supposing that their soldiers had been somewhere near unto the galleys. But it fell out that they were gone abroad to get their dinner, not in the market (for by set purpose of the Eretrians, to the end that the enemy might fall upon the Athenians that embarked slowly before they were ready and force them to come out and fight, nothing was there to be sold), but in the utmost houses of the city.

There was besides a sign set up at Eretria to give them notice at Oropus at what time to set forward. The Athenians, drawn out by this device and fighting before the haven of Eretria, made resistance nevertheless for a while; but afterwards they turned their backs and were chased ashore.

Such as fled to the city of the Eretrians, taking it for their friend, were handled most cruelly and slaughtered by them of the town; but such as got to the fort in Eretria, holden by the Athenians, saved themselves; and so did so many of their galleys as got to Chalcis.
