History of the Peloponnesian War

This was without doubt the largest army of Athenians ever assembled, the state being still in the flower of her strength and yet unvisited by the plague. Full ten thousand heavy infantry were in the field, all Athenian citizens, besides the three thousand before Potidaea. Then the resident aliens who joined in the incursion were at least three thousand strong; besides which there was a multitude of light troops. They ravaged the greater part of the territory, and then retired.

Other incursions into the Megarid were afterwards made by the Athenians annually during the war, sometimes only with cavalry, sometimes with all their forces. This went on until the capture of Nisaea.

Atalanta also, the desert island off the Opuntian coast, was towards the end of this summer converted into a fortified post by the Athenians, in order to prevent privateers issuing from Opus and the rest of Locris and plundering Euboea. Such were the events of this summer after the return of the Peloponnesians from Attica.
