The Historians' History of the World 02

These troops were distributed through the provinces by thousands, and their commanders consequently denominated Chiliarchs; and not only were they generally dispersed over the country, but bodies of them were posted on the boundaries, where, if the nature of the ground permitted it, the passage from one province to another was strongly fortified. It certainly remains a question what was the strength of these forces in the provinces, but the great facility with which armies were got together proves them to have been very considerable. In Asia Minor alone Cyrus assembled above one hundred thousand men; Abrocomas, who was opposed to him on his march, had three hundred thousand; and the Persian army on the Granicus was forty thousand strong.

From these troops the garrisons in the cities were kept entirely distinct, and the importance attached by the Persians to places of strength was in proportion to the difficulty which (like all other nomad nations, who know nothing about the conduct of sieges) they had experienced in subduing them. They were looked upon as the keys of the provinces in which they were situated, and accordingly provided with ample garrisons. The troops in question were completely different from those mentioned above, not being comprehended in the military divisions alluded to, but being under commanders of their own, and not bound to appear at the general muster.

Both descriptions of forces were, however, comprehended under the title of the king’s army, and were distinct from the household troops of the satraps and grandees, which often amounted to several thousands. By the customs of the East every great man is attended by an armed retinue, proportioned to his rank and wealth, and as the viceregal courts were formed upon the model of the king’s, this became necessarily a part of their establishments, and the more readily as corps of troops were a no less customary present from the monarch to his favourites than were cities.

Originally, it is probable that all these troops may have been Persians, but as these gradually withdrew themselves from martial duties, their places were supplied by mercenaries, Greeks or Asiatics. As cavalry, the nomad nations to the south and east of the Caspian were preferred, the Hyrcanians, Parthians, and Sacæ. The first, especially, had a high character with the Persians for courage, and on this account the latter kept up a good understanding with the wandering hordes of Great Bucharia, though no longer their tributaries. The Greeks, however, were preferred to all the rest, and as early as the time of the younger Cyrus, not only did the flower of the army always consist of them, but towards the end of the Persian monarchy they constituted the garrisons of all the cities of Asia Minor. Before the time of the younger Cyrus their pay amounted to a daric per month (about 1l. 0s. 4d. sterling), which was augmented by Cyrus to a daric and a half. We have already remarked the fatal consequences which this custom had on the warlike temper of the Persians.

In a nation of conquerors every individual is expected to be a soldier, and among the Persians all, especially those in possession of lands, were required to be able to serve on horseback. This necessitated an internal constitution of the whole empire, having for its object the military equipment of the population; and the arrangement adopted has usually been the same in all Asiatic nations, and is the simplest that could have been devised. A decimal system runs through the whole empire, and serves at the same time to mark the rank of the commander. The common people are divided into bodies of ten, having a captain of that number, after whom come the commanders of hundreds, thousands, and tens of thousands. Officers of a higher rank are not apportioned to particular bodies of men, but form the general staff. This has been equally the case among the Mongols and the Persians, and this simple arrangement made it possible for both races to assemble large armies with incredible rapidity. All that was required was a mandate from the commander of ten thousand, which was transmitted to the commanders of thousands, and hundreds, and tens, till the forces, already organised, assembled in martial array. In this manner the Mongol princes often got together, in a few days, armies of cavalry to the number of several hundreds of thousands, and we cannot, therefore, be astonished to see the same thing take place among the Persians.
