It is clear, however, that they had advanced beyond the first period in military matters, when men fight in a confused mass of mingled horse, foot, and chariots, heavy-armed and light-armed spear-men, archers, and stingers, each standing and moving as mere chance may determine.

It is even certain that they had advanced beyond the second period, when the phalanx order of battle is adopted, the confused mass being replaced by a single serried body presenting its best armed troops to the enemy, and keeping in the rear, to add their weight to the charge, the weaker and more imperfectly protected.

It was not really left for Cyaxares the Mede to be the first to organize an Asiatic army--to divide the troops into companies and form distinct bodies of the spearmen, the archers, and the cavalry.

The Assyrian troops were organized in this way, at least from the time of Sennacherib, on whose sculptures we find, in the first place, bodies of cavalry on the march unaccompanied by infantry; secondly, engagements where cavalry only are acting against the enemy; thirdly, long lines of spearmen on foot marching in double file, and sometimes divided into companies; and, fourthly, archers drawn up together, but similarly divided into companies, each distinguished by its own uniform.

We also meet with a corps of pioneers, wearing a uniform and armed only with a hatchet, and with bodies of slingers, who are all armed and clothed alike.
