This disastrous battle was speedily followed by the overthrow of the Athenian empire in Thrace. At the request of Perdiccas, King of Macedonia, and of the Chalcidian towns, who had sued for help against the Athenians, Brasidas was sent by the Lacedaemonian government into Macedonia, at the head of a small body of troops. On his arrival in Macedonia he proclaimed that he was come to deliver the Grecian cities from the tyrannous yoke of Athens. His bravery, his kind and conciliating demeanour, his probity, moderation, and good faith, soon gained him the respect and love of the allies of Athens in that quarter. Acanthus and Stagirus hastened to open their gates to him; and early in the ensuing winter, by means of forced marches, he suddenly and unexpectedly appeared before the important Athenian colony of Amphipolis on the Strymon. In that town the Athenian party sent a message for assistance to Thucydides, the historian, who was then general in those parts. Thucydides hastened with seven ships from Thasos, and succeeded in securing Eion at the mouth of the Strymon; but Amphipolis, which lay a little higher up the river, allured by the favourable terms offered, had already surrendered to Brasidas. For his want of vigilance on this occasion, Thucydides was, on the motion of Cleon, sentenced to banishment, and spent the following twenty years of his life in exile. Torone, Scione, and other towns also revolted from Athens. In the following year (B.C. 422) Cleon was sent to Macedonia to recover the Athenian dependencies, and especially Amphipolis. He encamped on a rising ground on the eastern side of the town. Having deserted the peaceful art of dressing hides for the more hazardous trade of war, in which he was almost totally inexperienced, and having now no Demosthenes to direct his movements, Cleon was thrown completely off his guard by a very ordinary stratagem on the part of Brasidas, who contrived to give the town quite a deserted and peaceful appearance. Cleon suffered his troops to fall into disorder, till he was suddenly surprised by the astounding news that Brasidas was preparing for a sally. Cleon at once resolved to retreat. But his skill was equal to his valour. He conducted his retreat in the most disorderly manner. His left wing had already filed off and his centre with straggling ranks was in the act of following, when Brasidas ordered the gates of the town to be flung open, and, rushing out at the head of only 150 chosen soldiers, charged the retreating columns in flank. They were immediately routed; but Brasidas received a mortal wound and was carried off the field. Though his men were forming on the hill, Cleon fled as fast as he could on the approach of the enemy, but was pursued and slain by a Thracian peltast. In spite, however, of the disgraceful flight of their general, the right wing maintained their ground for a considerable time, till some cavalry and peltasts issuing from
