Ενώ δε οι πολέμιοι έλέγοντο μεν προσιέναι, παρήσαν δε ουδέπω, εν τούτω επειράτο και Κυρος ασκείν μεν τα σώματα των μεθ' εαυτού εις ισχύν, διδάσκειν δε τα τακτικά, θήγειν δε τας ψυχάς εις τα πολεμικά. Και πρώτον μεν λαβών παρά Κυαξάρου υπηρέτας προσέταξεν εκάστους των στρατιωτων ικανώς, ών έδέοντο, πάντα πεποιημένα παρασχεϊν τούτο δε παρασκευάσας ουδέν αυτοίς άλλο έλελοίπει ή ασκεϊν τα αμφί τον πόλεμον, εκείνο δοκών καταμεμαθηκέναι, ότι ούτοι κράτιστοι έκαστα γίγνονται, οι αν αφέμενοι του πολλοίς προσέχειν τον νούν επί έν έργον τράπωνται. και αυτών δε των πολεμικών περιελών και το τόξω μελετών και ακοντίω, κατέλιπε τούτο μόνον αυτοίς το σύν μαχαίρα και γέρρω και θώρακι μάχεσθαι ώστε ευθύς αυτών παρεσκεύασε τας γνώμας, ως ομόσε ιτέον είη τοΐς πολεμίοις, ή ομολογητέον μηδενός είναι άξιους συμμάχους τούτο δε χαλεπόν ομολογήσαι, οίτινες αν είδωσιν, ότι ουδέ δι' έν άλλο τρέφονται και όπως μαχούνται υπέρ των τρεφόντων.

For Greek Prose :

He then told the Chaldeans, that he was not come either with a desire to destroy them, or with an inclination to make war upon them ; but with a wish to make peace between the Armenians and Chaldeans. “ Before your mountains were occupied,” said he, "I know that you had no desire for peace : your own possessions were in safety; those of the Armenians you plundered and ravaged. But you now see in what condition you are placed. Those of you, therefore, that have been taken I dismiss to your homes, and allow you, together with the rest of the Chaldeans, to consult amongst yourselves, whether you are inclined to make war with us, or to be our friends : if war be your choice, come no more hither without arms, if you are wise; if you resolve to prefer peace, come without arms. And, if you become our friends, it shall be my care that your affairs be established upon the best footing.' The Chaldeans hearing these assurances, and bestowing many praises upon Cyrus, and giving him many pledges of friendship, went home.
