History of the Peloponnesian War

The Athenians then, having put out with such scanty preparations, and fought a battle off the harbour of Eretria, held out against them, notwithstanding, for some little time, and were then put to flight and pursued to the shore.

And now such of them as took refuge in the city of the Eretrians, as being friendly to them, fared worst of all, for they were butchered by them; but those who fled to the fort in the Eretrian territory, which the Athenians themselves occupied, were saved;

as also were all the ships that reached Chalcis. The Peloponnesians, having taken two and twenty of the Athenian vessels, and either killed or made prisoners of the men, erected a trophy. And not long after they effected the revolt of the whole of Euboea, excepting Oreus, (which was held by the Athenians themselves,) and arranged all other matters thereabout.
