Nicias tried to reach them by a path up the hill, having with him one hundred and twenty light-armed Methonaeans, sixty picked men of the Athenian hoplites, and all the bowmen, but his troops suffered in the attempt and he was unable to carry this position. Nicostratus, however, with all the rest of the army, advancing against the hill, which was difficult of access, by another and longer route, was thrown into utter confusion, and the whole Athenian army narrowly escaped defeat.
So on this day, as the Mendaeans and their allies did not yield, the Athenians withdrew and encamped, and the Mendaeans, when night came on, returned to the city.
On the next day the Athenians sailed round to the side of the town facing Scione and took the suburb, and all that day they ravaged the land. No one came out against them, as there was some sort of uprising in the town; and during the following night the three hundred Scionaeans returned home.
On the next day Nicias with half of the army advanced as far as the boundary of the Scionaeans and ravaged the land, while Nicostratus with the rest sat down before the city at the upper gates, on the road leading to Potidaea.
But it chanced that in that quarter of the town, inside the walls, the arms of the Mendaeans and their auxiliaries were deposited, and Polydamidas was there drawing his troops up for battle and exhorting the Mendaeans to make a sortie.
Some one of the popular party mutinously answered him that he would not go out and had no use for war, but no sooner had he answered than Polydamidas seized him with violence and roughly handled him; whereupon the populace in great anger at once caught up their arms and advanced upon the Peloponnesians and the opposite party who were in league with them.
Falling upon them they put them to rout, partly by the suddenness of their onslaught, partly because the others were terrified when the gates were opened to the Athenians; for they thought that the attack had been made upon them by a preconcerted agreement.
Those of the Peloponnesians who were not killed on the spot took refuge on the acropolis, which they already had possession of; but the Athenians—for Nicias had already turned back and was near the city— burst into the city with their whole force, and, as the gates had been opened without an agreement, plundered the city as though they had taken it by storm; and the generals with difficulty kept them from destroying the inhabitants also.
They then directed the Mendaeans henceforth to retain their former constitution, and bring to trial among themselves any whom they thought guilty of the revolt; but the men on the acropolis they fenced off with a wall extending on either side down to the sea, and set a guard over them. And when they had thus secured Mende, they proceeded against Scione.
The Scionaeans and the Peloponnesians had come out against them and taken position on a strong hill before the city, which had to be taken by the enemy before the city could be invested with a wall.
So the Athenians made a furious assault upon the hill and dislodged those that were upon it; they then encamped and, after raising a trophy, prepared for the circumvallation.
But not long afterwards, when they were already at work, the auxiliaries who were besieged on the acropolis of Mende forced their way by night along the shore through the guard and reached Scione; and most of them escaped through the besieging army and got into the city.
While the circumvallation of Scione was in progress, Perdiccas sent a herald to the Athenian generals and made an agreement with them; he was moved to this by the hatred he bore Brasidas for his retreat from Lyncus, at which time indeed he had begun his negotiations.[*](cf. 4.128.5.)
Now it happened at that time that Ischagoras, the Lacedaemonian, was on the point of taking an army by land to join Brasidas, but Perdiccas, partly because Nicias urged him, since he had made terms with the Athenians, to give them some token of his sincerity, partly also because he himself no longer wished the Peloponnesians to enter his territory, now worked upon his friends in Thessaly, with the foremost of whom he was always on good terms, and effectually stopped the army and the expedition, to such a degree that they did not even try to obtain permission from the Thessalians.
