§5.40.1ἅμα δὲ τῷ ἦρι εὐθὺς τοῦ ἐπιγιγνομένου θέρους οἱ Ἀργεῖοι, ὡς οἵ τε πρέσβεις τῶν Βοιωτῶν οὓς ἔφασαν πέμψειν οὐχ ἧκον τό τε Πάνακτον ᾔσθοντο καθαιρούμενον καὶ ξυμμαχίαν ἰδίαν γεγενημένην τοῖς Βοιωτοῖς πρὸς τοὺς Λακεδαιμονίους, ἔδεισαν μὴ μονωθῶσι καὶ ἐς Λακεδαιμονίους πᾶσα ἡ ξυμμαχία χωρήσῃ·
At the very beginning of the spring of the ensuing summer, the Argives, when they saw that the Boeotian envoys whom they had said they would send did not arrive, and learned that Panactum was being demolished and that a separate alliance had been concluded between the Boeotians and the Lacedaemonians, feared that they might be left isolated and that their whole alliance might go over to the Lacedaemonians.
§5.40.2τοὺς γὰρ Βοιωτοὺς ᾤοντο πεπεῖσθαι ὑπὸ Λακεδαιμονίων τό τε Πάνακτον καθελεῖν καὶ ἐς τὰς Ἀθηναίων σπονδὰς ἐσιέναι, τούς τε Ἀθηναίους εἰδέναι ταῦτα, ὥστε οὐδὲ πρὸς Ἀθηναίους ἔτι σφίσιν εἶναι ξυμμαχίαν ποιήσασθαι, πρότερον ἐλπίζοντες ἐκ τῶν διαφορῶν, εἰ μὴ μείνειαν αὐτοῖς αἱ πρὸς Λακεδαιμονίους σπονδαί, τοῖς γοῦν Ἀθηναίοις ξύμμαχοι ἔσεσθαι.
For they thought that the Boeotians had been persuaded by the Lacedaemonians to demolish Panactum and to enter into the treaty with the Athenians, and that the Athenians were aware of this, so that it was no longer possible for them to make an alliance even with the Athenians, whereas they had previously hoped, in consequence of the differences, that if their treaty with the Lacedaemonians should not continue, they would at least be allies of the Athenians.
§5.40.3ἀποροῦντες οὖν ταῦτα οἱ Ἀργεῖοι, καὶ φοβούμενοι μὴ Λακεδαιμονίοις καὶ Τεγεάταις, Βοιωτοῖς καὶ Ἀθηναίοις ἅμα πολεμῶσι, πρότερον οὐ δεχόμενοι τὰς Λακεδαιμονίων σπονδάς, ἀλλ’ ἐν φρονήματι ὄντες τῆς Πελοποννήσου ἡγήσεσθαι, ἔπεμπον ὡς ἐδύναντο τάχιστα ἐς τὴν Λακεδαίμονα πρέσβεις Εὔστροφον καὶ Αἴσωνα, οἳ ἐδόκουν προσφιλέστατοι αὐτοῖς εἶναι, ἡγούμενοι ἐκ τῶν παρόντων κράτιστα πρὸς Λακεδαιμονίους σπονδὰς ποιησάμενοι, ὅπῃ ἂν ξυγχωρῇ, ἡσυχίαν ἔχειν.
The Argives, therefore, being at a loss in this situation, and fearing that they might have to wage war at the same time against the Lacedaemonians, Tegeans, Boeotians, and Athenians—although they had previously refused to accept the treaty of the Lacedaemonians, but had been high-minded enough to expect to lead the Peloponnese—sent as quickly as possible to Lacedaemon as envoys Eustrophus and Aeson, who were thought to be most friendly to them, thinking that, under the circumstances, it was best for them to make a treaty with the Lacedaemonians on whatever terms they could agree upon, and so remain quiet.
