The Peloponnesian squadron, however, sailed onward, doubled the promontory of Sunium,1
and then, after putting in between Thoricus and Prasiae, finally proneeded to Oropus.
The Athenians in their haste were compelled to employ crews not yet trained to work together, the city was in a state of revolution, and the matter was vital and urgent; Euboea was all in all to them now that they were shut out from Attica2
. They despatched a fleet under the command of Thymochares to Eretria;
these ships, added to those which were at Euboea before, made up thirty-six. No sooner had they arrived than they were constrained to fight; for Agesandridas, after his men had taken their midday meal, brought out his own ships from Oropus, which is distant by sea about seven miles from the city of Eretria, and bore down upon them.
The Athenians at once began to man their ships, fancying that their crews were close at hand; but it had been so contrived that they were getting their provisions from houses at the end of the town, and not in the market, for the Eretrians intentionally sold nothing there that the men might lose time in embarking; the enemy would then come upon them before they were ready, and they would be compelled to put out as best they could.
A signal was also raised at Eretria telling the fleet at Oropus when to attack. The Athenians putting out in this hurried manner, and fighting off the harbour of Eretria, nevertheless resisted for a little while, but before long they fled and were pursued to the shore.
Those of them who took refuge in the city of Eretria, relying on the friendship of the inhabitants, fared worst, for they were butchered by them; but such as gained the fortified position which the Athenians held in the Eretrian territory escaped, and also the crews of the vessels which reached Chalcis.
The Peloponnesians, who had taken twenty-two Athenian ships and had killed or made prisoners of the men, erected a trophy. Not long afterwards they induced all Euboea to revolt, except Oreus of which the Athenians still maintained possession. They then set in order the affairs of the island.
