(4.106) When the people heard the proclamation they began to waver; for very few of the citizens were Athenians, the greater number being a mixed multitude. Many within the walls were relatives of those who had been captured outside. In their alarm they thought the terms reasonable; the Athenian population because they were too glad to withdraw, reflecting how much greater their share of the danger was, and not expecting speedy relief; the rest of the people because they retained all their existing rights, and were delivered from a fate which seemed inevitable. The partisans of Brasidas now proceeded to justify his proposals without disguise, for they saw that the mind of the whole people had changed, and that they no longer paid any regard to the Athenian general who was on the spot. So his terms were accepted, and the city was surrendered and delivered up to him. On the evening of the same day Thucydides and his ships sailed into Eion, but not until Brasidas had taken possession of Amphipolis, missing Eion only by a night. For if the ships had not come to the rescue with all speed, the place would have been in his hands on the next morning.
(4.107) Thucydides now put Eion in a state of defence, desiring to provide not only against any immediate attempt of Brasidas, but also against future danger. He received the fugitives who had chosen to quit Amphipolis according to the agreement and wished to come into Eion. Brasidas suddenly sailed with a number of small craft down the river to Eion, hoping that he might take the point which runs out from the wall, and thereby command the entrance to the harbour; at the same time he made an attack by land. But in both these attempts he was foiled. Whereupon he returned, and took measures for the settlement of Amphipolis. Myrcinus a city in the Edonian country joined him, Pittacus the king of the Edonians having been assassinated by the children of Goaxis and Brauro his wife. Soon afterwards Galepsus and Oesymè (both colonies from Thasos) came over to him. Perdiccas likewise arrived shortly after the taking of Amphipolis, and assisted him in settling the newly-acquired towns.
(4.108) The Athenians were seriously alarmed at the loss of Amphipolis; the place was very useful to them, and supplied them with a revenue, and with timber which they imported for shipbuilding. As far as the Strymon the Lacedaemonians could always have found a way to the allies of Athens, if the Thessalians allowed them to pass; but until they gained possession of the bridge they could proceed no further, because, for a long way above, the river forms a large lake, and below, towards Eion, there were triremes on guard. All difficulty seemed now to be removed, and the Athenians feared that more of their allies would revolt. For Brasidas in all his actions showed himself reasonable, and whenever he made a speech lost no opportunity of declaring that he was sent to emancipate Hellas. The cities which were subject to Athens, when they heard of the taking of Amphipolis and of his promises and of his gentleness, were more impatient than ever to rise, and privately sent embassies to him, asking him to come and help them, every one of them wanting to be first. They thought that there was no danger, for they had under-estimated the Athenian power, which afterwards proved its greatness and the magnitude of their mistake; they judged rather by their own illusive wishes than by the safe rule of prudence. For such is the manner of men; what they like is always seen by them in the light of unreflecting hope, what they dislike they peremptorily set aside by an arbitrary conclusion. Moreover, the Athenians had lately received a blow in Boeotia, and Brasidas told the allies what was likely to attract them, but untrue, that at Nisaea the Athenians had refused to fight with his unassisted forces.70 And so they grew bold, and were quite confident that no army would ever reach them. Above all, they were influenced by the pleasurable excitement of the moment; they were now for the first time going to find out of what the Lacedaemonians were capable when in real earnest, and therefore they were willing to risk anything. The Athenians were aware of their disaffection, and as far as they could, at short notice and in winter time, sent garrisons to the different cities. Brasidas also despatched a message to the Lacedaemonians requesting them to let him have additional forces, and he himself began to build triremes on the Strymon. But they would not second his efforts because their leading men were jealous of him, and also because they preferred to recover the prisoners taken in the island and bring the war to an end.
After the taking of Amphipolis, Brasidas and his allies marched to the so-called Actè, or coastland, which runs out from the canal made by the Persian King and extends into the peninsula; it ends in Athos, a high mountain projecting into the Aegean sea.72 There are cities in the peninsula, of which one is Sanè, an Andrian colony on the edge of the canal looking towards the sea in the direction of Euboea; the others are Thyssus, Cleonae, Acrothoi, Olophyxus, and Dium; their inhabitants are a mixed multitude of barbarians, speaking Greek as well as their native tongue. A few indeed are Chalcidian; but the greater part are Pelasgians (sprung from the Tyrrhenians who once inhabited Lemnos and Athens), or Bisaltians, Crestonians, Edonians. They all dwell in small cities. Most of them joined Brasidas, but Sanè and Dium held out; whereupon he remained there for a time and wasted their territory.
(4.110) Finding that they would not yield, he promptly made an expedition against Toronè in Chalcidicè, which was held by the Athenians. He was invited by a few of the inhabitants, who were ready to deliver the city into his hands. Arriving at night, or about daybreak, he took up a position at the temple of the Dioscuri, which is distant about three furlongs from the city. The great body of the inhabitants and the Athenian garrison never discovered him; but those Toronaeans who were in his interest, and knew that he was coming, were awaiting his approach; some few of them had privately gone to meet him. When his confederates found that he had arrived, they introduced into the city, under the command of Lysistratus an Olynthian, seven light-armed soldiers carrying daggers (for of twenty who had been originally appointed to that service, only seven had the courage to enter). These men slipped in undiscovered by way of the wall where it looks towards the sea. They ascended the side of the hill on the slope of which the city is built, and slew the sentinels posted on the summit; they then began to break down the postern-gate towards the promontory of Canastraeum.
