History of the Peloponnesian War

But the Peloponnesian galleys, being now gone by and gotten about the promontory of Sunium, cast anchor between Thoricus and Prasiae and put in afterwards at Oropus.

The Athenians with all speed, constrained to make use of tumultuary forces, such as a city in time of sedition might afford, and desirous with all haste to make good their greatest stake (for Euboea, since they were shut out of Attica, was all they had), sent a fleet under the command of Timocharis to Eretria.

Which arriving, with those galleys that were in Euboea before, made up the number of six-and-thirty sail. And they were presently constrained to hazard battle; for Hegesandridas brought out his galleys from Oropus when he had first there dined. Now Oropus is from Eretria about threescore furlongs of sea.
