180 HISTORY OF GREECE Tinder the great mortality and pressure of sickness at Athens, their operations of war naturally languished ; while the enemies also, though more active, had but little success. A fleet of one hundred triremes, with one thousand hoplites on board, was sent by the Lacedaemonians under Knemus to attack Zakynthus, but accomplished nothing beyond devastation of the open parts of the island, and then returned home. And it was shortly after this, towards the month of September, that the Ambrakiots made an attack upon the Amphilochian town called Argos, situated on the southern coast of the gulf of Ambrakia: which town, as has been recounted in the preceding chapter, had been wrested from them two years before by the Athenians, under Phormio, and restored to the Amphilochians and Akarnanians.

Though the Peloponnesians were too inferior in maritime force to undertake formal war at sea against Athens, their single pri- vateers, especially the Megarian privateers from the harbor of .Nisaea, were active in injuring her commerce, 3 and not merely the commerce of Athens, but also that of other neutral Greeks, without scruple or discrimination.
