§4.23.1ἀφικομένων δὲ αὐτῶν διελέλυντο εὐθὺς αἱ σπονδαὶ αἱ περὶ Πύλον, καὶ τὰς ναῦς οἱ Λακεδαιμόνιοι ἀπῄτουν, καθάπερ ξυνέκειτο·
Upon their arrival, the truce concerning Pylos was immediately dissolved, and the Lacedaemonians demanded the return of their ships, as had been agreed.
οἱ δ’ Ἀθηναῖοι ἐγκλήματα ἔχοντες ἐπιδρομήν τε τῷ τειχίσματι παράσπονδον καὶ ἄλλα οὐκ ἀξιόλογα δοκοῦντα εἶναι οὐκ ἀπεδίδοσαν, ἰσχυριζόμενοι ὅτι δὴ εἴρητο, ἐὰν καὶ ὁτιοῦν παραβαθῇ, λελύσθαι τὰς σπονδάς.
But the Athenians, alleging as grievances an attack made upon the fort in violation of the treaty, and other matters which seemed of no great importance, refused to restore them, insisting that it had been expressly stated that if any point whatsoever were violated, the truce should be void.
οἱ δὲ Λακεδαιμόνιοι ἀντέλεγόν τε καὶ ἀδίκημα ἐπικαλέσαντες τὸ τῶν νεῶν ἀπελθόντες ἐς πόλεμον καθίσταντο.
The Lacedaemonians protested against this, and having denounced the detention of the ships as an injustice, they departed and entered upon war.
§4.23.2καὶ τὰ περὶ Πύλον ὑπ’ ἀμφοτέρων κατὰ κράτος ἐπολεμεῖτο, Ἀθηναῖοι μὲν δυοῖν νεοῖν ἐναντίαιν αἰεὶ τὴν νῆσον περιπλέοντες τῆς ἡμέρας (τῆς δὲ νυκτὸς καὶ ἅπασαι περιώρμουν, πλὴν τὰ πρὸς τὸ πέλαγος, ὁπότε ἄνεμος εἴη· καὶ ἐκ τῶν Ἀθηνῶν αὐτοῖς εἴκοσι νῆες ἀφίκοντο ἐς τὴν φυλακήν, ὥστε αἱ πᾶσαι ἑβδομήκοντα ἐγένοντο), Πελοποννήσιοι δὲ ἔν τε τῇ ἠπείρῳ στρατοπεδευόμενοι καὶ προσβολὰς ποιούμενοι τῷ τείχει, σκοποῦντες καιρὸν εἴ τις παραπέσοι ὥστε τοὺς ἄνδρας σῶσαι.
Thus the war around Pylos was vigorously prosecuted by both sides: the Athenians on their part constantly patrolled the island by day with two ships sailing in opposite directions (while by night all their ships lay at anchor around it for guard, except on the side facing the open sea whenever there was a wind; and twenty additional ships arrived from Athens to join the guard, so that they numbered seventy in all), while the Peloponnesians, encamped on the mainland and making assaults upon the fort, watched for any opportunity that might occur to rescue their men.
