Passage 4.8.9
ἐνταῦθα ἥ τε πᾶσα μάχη κεκμηκότων ὅμως ἐς τὸ ἀκμαιότατον αὖθις ἤρθη, καὶ τοῖς τε σώμασιν ἀνερρώννυντο καὶ τὸ ἀφειδὲς ἐς τὸν θάνατον παρʼ ἀμφοτέρων ηὐξάνετο, ὥστε εἰκάσαι ἄν τις τοῦ ἔργου τότε σφᾶς πρῶτον ἅπτεσθαι. τέλος δὲ οἱ περὶ τὸν Εὐφαῆ τῆς τε ἀπονοίας τῷ ὑπερβάλλοντι μανίας ὄντες ἐγγύτατα καὶ ὑπʼ ἀνδραγαθίας---πᾶν γὰρ δὴ τὸ περὶ τὸν βασιλέα οἱ λογάδες τῶν Μεσσηνίων ἦσαν---βιάζονται τοὺς ἀντιτεταγμένους· καὶ αὐτόν τε Θεόπομπον ἀπώσαντο καὶ Λακεδαιμονίων τοὺς καθʼ αὑτοὺς ἐτρέψαντο.
At this point, although exhausted, the whole battle once again rose to its highest intensity; their strength returned to their bodies, and their mutual disregard of death grew ever greater, so that one might suppose they were just beginning the conflict. Finally, Euphaes and his men, driven closest to madness by their extraordinary desperation and courage—for all those around the king were the elite of the Messenians—overpowered the opposing ranks. They repulsed Theopompus himself and routed the Lacedaemonians facing them.
