History of the Peloponnesian War

The next day the Athenians sailed round to the Scione side and took the suburb, and all day plundered the country, without any one coming out against them, partly because of intestine disturbances in the town; and the following night the three hundred Scionaeans returned home.

On the morrow Nicias advanced with half the army to the frontier of Scione and laid waste the country; while Nicostratus with the remainder sat down before the town near the upper gate on the road to Potidaea.

The arms of the Mendaeans and of their Peloponnesian auxiliaries within the wall happened to be piled in that quarter, where Polydamidas accordingly began to draw them up for battle, encouraging the Mendaeans to make a sortie.

At this moment one of the popular party answered him factiously that they would not go out and did not want a war, and for thus answering was dragged by the arm and knocked about by Polydamidas. Hereupon the infuriated commons at once seized their arms and rushed at the Peloponnesians and at their allies of the opposite faction.

The troops thus assaulted were at once routed, partly from the suddenness of the conflict and partly through fear of the gates being opened to the Athenians, with whom they imagined that the attack had been concerted.
