Their armies were divided into bodies of eight thousand men; and these, again, into companies of three or four hundred, each with its own commander. The national standard, which has been compared to the ancient Roman, displayed, in its embroidery of gold and feather-work, the armorial ensigns of the state. These were significant of its name, which, as the names of both persons and places were borrowed from some material object, was easily expressed by hieroglyphical symbols. The companies and the great chiefs had also their appropriate banners and devices, and the gaudy hues of their many-colored plumes gave a dazzling splendor to the spectacle.
Their tactics were such as belong to a nation with whom war, though a trade, is not elevated to the rank of a science. They advanced singing, and shouting their war-cries, briskly charging the enemy, as rapidly retreating, and making use of ambuscades, sudden surprises, and the light skirmish of guerilla warfare. Yet their discipline was such as to draw forth the encomiums of the Spanish conquerors. “A beautiful sight it was,” says one of them, “to see them set out on their march, all moving forward so gayly, and in so admirable order!”37 In battle they did not seek to kill their enemies, so much as to take them prisoners; and they never scalped, like other North American tribes. The valor of a warrior was estimated by the number of his prisoners; and no ransom was large enough to save the devoted captive.38
Their military code bore the same stern features as their other laws. Disobedience of orders was punished with death. It was death, also, for a soldier to leave his colors, to attack the enemy before the signal was given, or to plunder another’s booty or prisoners. One of the last Tezcucan princes, in the spirit of an ancient Roman, put two sons to death—after having cured their wounds—for violating the last-mentioned law.39
