Xenophon, Cyropaedia
Walter Miller, Ed.

Then, he had tents made for them—in number,¹ as many as there were captains; in size, large enough to accommodate each a company. A company, moreover, was composed of a hundred men. Accordingly, they lived in tents each company by itself; for Cyrus thought that in occupying tents together they had the following advantages for the coming conflict: They saw one another provided for in the same way, and there could be no possible pretext of unjust discrimination that could lead any one to allow himself to prove less brave than another in the face of the enemy. And he thought that if they tented together it would help them to get acquainted with one another. And in getting acquainted with one another, he thought, a feeling of considerateness was more likely to be engendered in them all, while those who are unacquainted seem somehow more indifferent—like people when they are in the dark.
