At the close of the same winter, in fact almost in spring, Brasidas made an attempt upon Potidæa. He arrived by night, and succeeded in planting a ladder against the wall without being discovered, the ladder being planted just in the interval between the passing round of the bell and the return of the man who brought it back. Upon the garrison, however, taking the alarm immediately afterwards, before his men came up, he quickly led off his troops, without waiting until it was day. So ended the winter and the ninth year of this war of which Thucydides is the historian. BOOK V CHAPTER XV Tenth Year of the War—Death of Cleon and Brasidas—Peace of Nicias The next summer the truce for a year ended, after lasting until the Pythian games. During the armistice the Athenians expelled the Delians from Delos, concluding that they must have been polluted by some old offence at the time of their consecration, and that this had been the omission in the previous purification of the island, which, as I have related, had been thought to have been duly accomplished by the removal of the graves of the dead. The Delians had Atramyttium in Asia given them by Pharnaces, and settled there as they removed from Delos. Meanwhile Cleon prevailed on the Athenians to let him set sail at the expiration of the armistice for the towns in the direction of Thrace with twelve hundred heavy infantry and three hundred horse from Athens, a large force of the allies, and thirty ships. First touching at the still besieged Scione, and taking some heavy infantry from the army there, he next sailed into Cophos, a harbour in the territory of Torone, which is not far from the town. From thence, having learnt from deserters that Brasidas was not in Torone, and that its garrison was not strong enough to give him battle, he advanced with his army against the town, sending ten ships to sail round into the harbour. He first came to the fortification lately thrown up in front of the town by Brasidas in order to take in the suburb, to do which he had pulled down part of the original wall and made it all one city. To this point Pasitelidas, the Lacedaemonian commander, with such garrison as there was in the place, hurried to repel the Athenian assault; but finding himself hard pressed, and seeing the ships that had been sent round sailing into the harbour, Pasitelidas began to be afraid that they might get up to the city before its defenders were there and, the fortification being also carried, he might be taken prisoner, and so abandoned the outwork and ran into the town. But the Athenians from the ships had already taken Torone, and their land forces following at his heels burst in with him with a rush over the part of the old wall that had been pulled down, killing some of the Peloponnesians and Toronaeans in the melee, and making prisoners of the rest, and Pasitelidas their commander amongst them. Brasidas meanwhile had advanced to relieve
