On his return from Macedonia to Torone, Brasidas found the Athenians already masters of Mende, and remained quiet where he was, thinking it now out of his power to cross over into Pallene and assist the Mendaeans, but he kept good watch over Torone. For about the same time as the campaign in Lyncus, the Athenians sailed upon the expedition which we left them preparing against Mende and Scione, with fifty ships, ten of which were Chians, one thousand Athenian heavy infantry and six hundred archers, one hundred Thracian mercenaries and some targeteers drawn from their allies in the neighbourhood, under the command of Nicias, son of Niceratus, and Nicostratus, son of Diitrephes. Weighing from Potidaea, the fleet came to land opposite the temple of Poseidon, and proceeded against Mende; the men of which town, reinforced by three hundred Scionaeans, with their Peloponnesian auxiliaries, seven hundred heavy infantry in all, under Polydamidas, they found encamped upon a strong hill outside the city. These Nicias, with one hundred and twenty light-armed Methonaeans, sixty picked men from the Athenian heavy infantry, and all the archers, tried to reach by a path running up the hill, but received a wound and found himself unable to force the position; while Nicostratus, with all the rest of the army, advancing upon the hill, which was naturally difficult, by a different approach further off, was thrown into utter disorder; and the whole Athenian army narrowly escaped being defeated. For that day, as the Mendaeans and their allies showed no signs of yielding, the Athenians retreated and encamped, and the Mendaeans at nightfall returned into the town.
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. As many as were not killed on the spot took refuge in the citadel, which they had held from the first; and the whole, Athenian army, Nicias having by this time returned and being close to the city, now burst into Mende, which had opened its gates without any convention, and sacked it just as if they had taken it by storm, the generals even finding some difficulty in restraining them from also massacring the inhabitants.
After this the Athenians told the Mendaeans that they might retain their civil rights, and themselves judge the supposed authors of the revolt; and cut off the party in the citadel by a wall built down to the sea on either side, appointing troops to maintain the blockade.
Having thus secured Mende, they proceeded against Scione.
