Passage 10.20.4
Λοκροὺς δὲ τοὺς ἐπὶ Ἀταλάντῃ τῇ νήσῳ Μειδίας ἦγεν· ἀριθμὸς δὲ αὐτῶν ἑπτακόσιοι, καὶ ἱππικόν σφισιν οὐ προσῆν. παρὰ δὲ Μεγαρέων ἀφίκοντο ὁπλῖται τετρακόσιοι· τούτων ἦγε τὸ †ἱππικὸν Μεγαρεύς. Αἰτωλῶν δὲ πλείστη τε ἐγένετο στρατιὰ καὶ ἐς πᾶσαν μάχης ἰδέαν, ἡ μὲν ἵππος οὐ λέγουσιν ὁπόση, ψιλοὶ δὲ ἐνενήκοντα καὶ ἑπτακόσιοι, πλέονες δὲ ἑπτακισχιλίων ἀριθμὸν ἦσαν οἱ ὁπλιτεύοντες· Αἰτωλοὺς δὲ ἦγον Πολύαρχος καὶ Πολύφρων τε καὶ Λακράτης.
The Locrians living by the island of Atalante were led by Meidias; they numbered seven hundred, and had no cavalry. From the Megarians came four hundred hoplites; their cavalry was commanded by Megareus. Of the Aetolians there was a very large force indeed, well-equipped for warfare of every kind; the cavalry, they say, was uncounted, the light-infantry numbered seven hundred and ninety, while those equipped as hoplites exceeded seven thousand in number. The Aetolians were under the command of Polyarchus, Polyphron, and Lacrates.
