It is only among Christians that there have been religious societies established for the purpose of fighting—as the Knights Templars, the Knights of St. John, the Knights of the Teutonic Order, the Knights Swordbearers. These religious orders were instituted in imitation of the Levites, who fought like the rest of the Jewish tribes.
Neither armies nor arms were the same in antiquity as at present. The Egyptians hardly ever had cavalry. It would have been of little use in a country intersected by canals, inundated during five months of the year, and miry during five more. The inhabitants of a great part of Asia used chariots of war.
They are mentioned in the annals of China. Confucius says that in his time each governor of a province furnished to the emperor a thousand war chariots, each drawn by four horses. The Greeks and Trojans fought in chariots drawn by two horses.
Cavalry and chariots were unknown to the Jews in a mountainous tract, where their first king, when he was elected, had nothing but she-asses. Thirty sons of Jair, princes of thirty cities, according to the text (Judges, x, 4), rode each upon an ass. Saul, afterwards king of Judah, had only she-asses; and the sons of David all fled upon mules when Absalom had slain his brother Amnon. Absalom was mounted on a mule in the battle which he fought against his father's troops; which proves, according to the Jewish historians, either that mares were beginning to be used in Palestine, or that they were already rich enough there to buy mules from the neighboring country.
The Greeks made but little use of cavalry. It was chiefly with the Macedonian phalanx that Alexander gained the battles which laid Persia at his feet. It was the Roman infantry that subjugated the greater part of the world. At the battle of Pharsalia, Cæsar had but one thousand horsemen.
It is not known at what time the Indians and the Africans first began to march elephants at the head of their armies. We cannot read without surprise of Hannibal's elephants crossing the Alps, which were much harder to pass then than they are now.
There have long been disputes about the disposition of the Greek and Roman armies, their arms, and their evolutions. Each one has given his plan of the battles of Zama and Pharsalia.
The commentator Calmet, a Benedictine, has printed three great volumes of his "Dictionary of the Bible," in which, the better to explain God's commandments, are inserted a hundred engravings, where you see plans of battles and sieges in copper-plate. The God of the Jews was the God of armies, but Calmet was not His secretary; he cannot have known, but by revelation, how the armies of the Amalekites, the Moabites, the Syrians, and the Philistines were arranged on the days of general murder. These plates of carnage, designed at a venture, made his hook five or six louis dearer, but made it no better.
It is a great question whether the Franks, whom the Jesuit Daniel calls French by anticipation, used bows and arrows in their armies, and whether they had helmets and cuirasses.
Supposing that they went to combat almost naked, and armed, as they are said to have been, with only a small carpenter's ax, a sword, and a knife, we must infer that the Romans, masters of Gaul, so easily conquered by Clovis, had lost all their ancient valor, and that the Gauls were as willing to be subject to a small number of Franks as to a small number of Romans. Warlike accoutrements have since changed, as everything else changes.
