This mood description comes at a compositionally important place, namely, the zenith of Achenian success. The Athenian setback in Megara (4.66 ff.) follows immediately and simultaneously forms the first (70.1 ff.) in Brasidas' string of victories. Spartan 'misfortune'(79.3) leads to a counterattack (‘divert [them, scil the Athenians]’, if they harmed them in turn, 80.1) against the Athenian territories on the Thracian coast.Parallel to Brasidas' successes run the Athenian preparations for a pincer movement against Boeotia (77; 89 ff), in which Demosthenes' old plan (which had failed so miserably at Aigition) is resurrected, But a ridiculous mistake in the time calculation (89.1) spoils the synchronized departures on which the plan is based and leads to the Athenian debadle at Delium (96). The loss of Amphipolis finally (103 ff.) generates serious fears (108.1) in Athens for the Thracian territories. Sparta, on the other hand, cannot really enjoy is victories in the north-east because the men of Sphakteria are still Athenian prisoners (117.1; cf. 5.14.3; 15.1). Thus it comes to the armistice of the spring of 423 (4.117 f.), which in the following year, after the deaths of Brasidas and Cleon, passes into the Peace of Nicias.
