[67] He remembered how his Persians led the sorriest of lives at home owing to their poverty, working long and hard on the niggard soil, and he felt sure they were the men who would most value the life at his court.

[68] Accordingly he selected ten thousand lancers from among them, to keep guard round the palace, night and day, whenever he was at home, and to march beside him whenever he went abroad.

[69] Moreover, he felt that Babylon must always have an adequate garrison, whether he was in the country or not, and therefore he stationed a considerable body of troops in the city; and he bade the Babylonians provide their pay, his object being to make the citizens helpless, and therefore humble and submissive.

[70] This royal guard that he established there, and the city guard for Babylon, survive to this day unaltered.
Lastly, as he pondered how the whole empire was to be kept together, and possibly another added to it, he felt convinced that his mercenaries did not make up for the smallness of their numbers by their superiority to the subject peoples.

Therefore he must keep together those brave warriors, to whom with heaven's help the victory was due, and he must take all care that they did not lose their valour, hardihood, and skill.
[71] To avoid the appearance of dictating to them and to bring it about that they should see for themselves it was best to stay with him and remember their valour and their training, he called a council of the Peers and of the leading men who seemed to him most worthy of sharing their dangers and their rewards.
