Passage 10.1.5
ταῦτα ὡς ἐπύθοντο οἱ Φωκεῖς, λογάδας τριακοσίους καὶ Γέλωνα ἐπʼ αὐτοῖς ἄρχοντα ἀποστέλλουσιν ἐς τοὺς πολεμίους ἄρτι ἀρχομένης νυκτός, προστάξαντές σφισι κατοπτεῦσαί τε τὰ τῶν Θεσσαλῶν ὅντινα ἀφανέστατον δύναιντο τρόπον καὶ αὖθις ἐς τὸ στράτευμα ἐπανήκειν κατὰ τῶν ὁδῶν τὴν μάλιστα ἄγνωστον, μηδὲ ἑκόντας μάχης ἄρχειν. οὗτοι ὑπὸ τῶν Θεσσαλῶν οἱ λογάδες ἀπώλοντο ἀθρόοι καὶ αὐτοὶ καὶ ὁ ἡγούμενός σφισι Γέλων, συμπατούμενοί τε ὑπὸ τῶν ἵππων καὶ ὑπὸ τῶν ἀνδρῶν φονευόμενοι.
When the Phocians learned this, they dispatched three hundred picked men, under the command of Gelon, against the enemy just as night was beginning. Their orders were to secretly observe the Thessalians' arrangements as discreetly as possible, and then return to their camp by the least known roads, making sure they did not willingly initiate combat. These chosen men, including their leader Gelon himself, were wholly destroyed by the Thessalians, trampled beneath their horses' hooves and slain by their soldiers.
