Amphipolis attacked them in flank and rear, and compelled them to fly. On assembling again at Eion it was found that half the Athenian hoplites had been slain. Brasidas was carried into Amphipolis, and lived long enough to receive the tidings of his victory. He was interred within the walls with great military pomp in the centre of what thenceforth became the chief agora; he was proclaimed oecist, or founder of the town; and was worshipped as a hero with annual games and sacrifices. By the death of Brasidas and Cleon the two chief obstacles to a peace were removed; for the former loved war for the sake of its glory, the latter for the handle which it afforded for agitation and for attacking his political opponents. The Athenian Nicias, and the Spartan king Pleistoanax, zealously forwarded the negotiations, and in the spring of the year B.C. 421 a peace for 50 years, commonly called the PEACE OF NICIAS, was concluded on the basis of a mutual restitution of prisoners and places captured during the war. CHAPTER XII. THE PELOPONNESIAN WAR.--SECOND PERIOD, FROM THE PEACE OF NICIAS TO THE DEFEAT OF THE ATHENIANS IN SICILY, B.C. 421-413. Several of the allies of Sparta were dissatisfied with the peace which she had concluded; and soon afterwards some of them determined to revive the ancient pretensions of Argos, and to make her the head of a new confederacy, which should include all Greece, with the exception of Sparta and Athens. The movement was begun by the Corinthians, and the league was soon joined by the Eleans, the Mantineans, and the Chalcidians.
