The Retreat of the Ten Thousand by C. Witt

It was about the ninth day of March in the year 401 B. C., that the army of Cyrus began to set forward. Cyrus was commander-in-chief of the whole army, but the two divisions were kept entirely separate, each under its own officers. The Asiatic troops, who numbered 100,000, were under the command of Arieus, one of the most distinguished of the Persian supporters of Cyrus. The Hellene force, which consisted of 13,000 men, and was afterwards increased by another thousand, was composed of a number of different companies, each commanded by the general who had raised it, and smaller or larger according to his success in getting recruits. Under the generals were captains, who each had command of a hundred men, and whose numbers consequently varied in each company with the number of the soldiers.

Of the Persian troops, the most brilliant and useful were the cavalry. The Persians had long been famous for their skill and activity as horsemen; they were also excellent archers, and could draw their long bows at full gallop with as accurate an aim as if they were standing still and undisturbed on solid ground.
