History of the Peloponnesian War

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.
