Passage 4.16.4
τούτοις μὲν δὴ φεύγουσι διώκειν ἐπέταξεν ὁ Ἀριστομένης ἕτερον τῶν Μεσσηνίων λόχον· αὐτὸς δὲ ὁρμήσας πρὸς τὸ μάλιστα ἀνθεστηκός, ὡς ἐβιάσατο καὶ τούτους, ἐπʼ ἄλλους ἐτράπετο αὖθις. ταχὺ δὲ καὶ τούτους ὠσάμενος ἑτοιμότερον ἤδη πρὸς τοὺς ὑπομένοντας ἐπεφέρετο, ἐς ὃ πᾶσαν τῶν Λακεδαιμονίων τὴν τάξιν καὶ αὐτῶν καὶ τῶν συμμάχων συνέχεε· καὶ οὐχὶ σὺν αἰδοῖ φευγόντων οὐδὲ ἀναμένειν θελόντων ἔτι ἀλλήλους, ἐπέκειτό σφισι φοβερώτερος ἢ κατὰ ἀνδρὸς ἑνὸς εἶναι μανίαν.
Aristomenes then commanded another division of the Messenians to pursue those who fled. He himself charged against those who still resisted strongly, and having forced these back as well, he immediately turned upon others. Quickly pushing these aside, he advanced now with even greater eagerness against those who still held their ground, until he utterly threw into confusion the whole Spartan battle-line together with their allies. As they fled without shame, no longer willing even to wait for one another, Aristomenes pressed upon them, terrifying them beyond what might be expected from the fury of a single man.
