§2.12.1τοσαῦτα εἰπὼν καὶ διαλύσας τὸν ξύλλογον ὁ Ἀρχίδαμος Μελήσιππον πρῶτον ἀποστέλλει ἐς τὰς Ἀθήνας τὸν Διακρίτου ἄνδρα Σπαρτιάτην, εἴ τι ἄρα μᾶλλον ἐνδοῖεν οἱ Ἀθηναῖοι ὁρῶντες σφᾶς ἤδη ἐν ὁδῷ ὄντας.
Having said this much and dismissed the assembly, Archidamus first sent Melesippus, son of Diacritus, a Spartan, to Athens, in case the Athenians might show themselves more inclined to yield now that they saw them already on the march.
§2.12.2οἱ δὲ οὐ προσεδέξαντο αὐτὸν ἐς τὴν πόλιν οὐδ’ ἐπὶ τὸ κοινόν· ἦν γὰρ Περικλέους γνώμη πρότερον νενικηκυῖα κήρυκα καὶ πρεσβείαν μὴ προσδέχεσθαι Λακεδαιμονίων ἐξεστρατευμένων·
But they did not admit him into the city or to the public assembly; for a proposal of Pericles had previously prevailed, that they should not receive any herald or embassy from the Lacedaemonians once they had taken the field.
ἀποπέμπουσιν οὖν αὐτὸν πρὶν ἀκοῦσαι καὶ ἐκέλευον ἐκτὸς ὅρων εἶναι αὐθημερόν, τό τε λοιπὸν ἀναχωρήσαντας ἐπὶ τὰ σφέτερα αὐτῶν, ἤν τι βούλωνται, πρεσβεύεσθαι.
They therefore sent him back before hearing him, and ordered him to be beyond the borders on that very day, and that in the future, only after they had retired to their own territory, they might send embassies if they wished.
ξυμπέμπουσί τε τῷ Μελησίππῳ ἀγωγούς, ὅπως μηδενὶ ξυγγένηται.
They also sent guards with Melesippus to accompany him, so that he might hold communication with no one.
§2.12.3ὁ δ’ ἐπειδὴ ἐπὶ τοῖς ὁρίοις ἐγένετο καὶ ἔμελλε διαλύσεσθαι, τοσόνδε εἰπὼν ἐπορεύετο ὅτι ‘ἥδε ἡ ἡμέρα τοῖς Ἕλλησι μεγάλων κακῶν ἄρξει. ’ §2.12.4ὡς δὲ ἀφίκετο ἐς τὸ στρατόπεδον καὶ ἔγνω ὁ Ἀρχίδαμος ὅτι οἱ Ἀθηναῖοι οὐδέν πω ἐνδώσουσιν, οὕτω δὴ ἄρας τῷ στρατῷ προυχώρει ἐς τὴν γῆν αὐτῶν.
And when he arrived at the borders and was about to part from them, he went on his way, saying only this: 'This day will be the beginning of great evils for the Hellenes.' When he returned to the camp and Archidamus realized that the Athenians would not yet make any concession, he then at last broke camp with his army and advanced into their territory.
§2.12.5Βοιωτοὶ δὲ μέρος μὲν τὸ σφέτερον καὶ τοὺς ἱππέας παρείχοντο Πελοποννησίοις ξυστρατεύειν, τοῖς δὲ λειπομένοις ἐς Πλάταιαν ἐλθόντες τὴν γῆν ἐδῄουν.
Meanwhile, the Boeotians furnished their own contingent and their cavalry to campaign with the Peloponnesians, while with the remainder of their forces they marched to Plataea and ravaged their land.
