§20.11.1ἔμελλον ὅπερ εἰκὸς οἱ ὁπλῖται κράνεσι καὶ θώραξι καὶ θυρεοῖς βαρεῖς πρὸς ὀχθηρὰ χωρία καὶ μακρὰς ἀτραποὺς πορευόμενοι καὶ οὐδὲ ταύτας λεωφόρους, ἀλλʼ αἰγότριβας διʼ ὕλης τε καὶ κρημνῶν τάξιν τε οὐδεμίαν φυλάξειν, καὶ πρὶν ἐπιφανῆναί σφισι τοὺς πολεμίους ἐξασθενήσειν τὰ σώματα δίψει καὶ κόπῳ.
As was to be expected, the hoplites, heavy with helmets, breastplates, and shields, marching toward hilly places and along long paths—and these not highways, but goat-tracks through woods and cliffs—were bound to keep no order at all, and even before the enemy should appear to them, to have their bodies exhausted by thirst and fatigue.
§20.11.2τοὺς τοῖς ἱππικοῖς δόρασιν ἐκ διαλαβῆς ἀμφοτέραις ταῖς χερσὶ κρατουμένοις μαχομένους συστάδην καὶ τὰ πολλὰ κατορθοῦντας ἐν ταῖς μάχαις Πρίγκιπας Ῥωμαῖοι καλοῦσιν.
Those who fight hand-to-hand with cavalry spears held with both hands at an interval, and who are for the most part successful in battles, the Romans call "Principes."
