but native Athenian soldiers, until farther progress should be made in the peace. But the feeling of the Athenians was now seriously altered, and they received this demand with marked coldness. None of the stipulations of the treaty in their favor had yet been performed, none even seemed in course of being performed: so that they now began to suspect Sparta of dishonesty and deceit, and deeply regretted their inconsiderate surrender of the captives.[15] Their remonstrances at Sparta, often repeated during the course of the summer, produced no positive effect: nevertheless, they suffered themselves to be persuaded to remove the Messenians and Helots from Pylus to Kephallenia, replacing them by an Athenian garrison.[16] [14] Thucyd. v, 35. λέγοντες ἀεὶ ὡς μετ’ Ἀθηναίων τούτους, ἢν μὴ θέλωσι, κοινῇ ἀναγκάσουσι· ~χρόνους δὲ προὔθεντο ἄνευ ξυγγραφῆς~, ἐν οἷς χρῆν τοὺς μὴ ἐσιόντας ἀμφοτέροις πολεμίους εἶναι. [15] Thucyd. v, 35. τούτων οὖν ὁρῶντες οἱ Ἀθηναῖοι οὐδὲν ἔργῳ γιγνόμενον, ὑπετόπευον τοὺς Λακεδαιμονίους μηδὲν δίκαιον διανοεῖσθαι, ὥστε οὔτε Πύλον ἀπαιτούντων αὐτῶν ἀπεδίδοσαν, ἀλλὰ ~καὶ τοὺς ἐκ τῆς νήσου ἄνδρας μετεμέλοντο ἀποδεδωκότες~, etc. [16] Thucyd. v, 35. πολλάκις δὲ καὶ πολλῶν λόγων γενομένων ἐν τῷ θέρει τούτῳ, etc. The Athenians had doubtless good reason to complain of Sparta. But the persons of whom they had still better reason to complain, were Nikias and their own philo-Laconian leaders; who had first accepted from Sparta promises doubtful as to execution, and next—though favored by the lot in regard to priority of cession, and thus acquiring proof that Sparta either would not or could not perform her promises—renounced all these advantages, and procured for Sparta almost gratuitously the only boon for which she seriously cared. The many critics on Grecian history, who think no term too harsh for the demagogue Kleon, ought in fairness to contrast his political counsel with that of his rivals, and see which of the two betokens greater forethought in the management of the foreign relations of Athens. Amphipolis had been once lost by the improvident watch of Thucydidês and Euklês: it was now again lost by the improvident concessions of Nikias.
