One of the earliest descriptions of war is to be found in the Iliad of Homer, where individual heroes fought with one another, armed with the sword, the lance, and the javelin, protected by shields, helmets, and coats of mail. They fought on foot, or from chariots, which were in use before cavalry. The war-horse was driven before he was ridden in Egypt or Palestine; but the Aryan barbarians in their invasion rode their horses, and fought on horseback, like the modern Cossacks.

Until the Greeks became familiar with war as an art, armies were usually very large, as if a great part of the population of a country followed the sovereign who commanded them. Rameses the Great, the Sesostris of the Greeks, according to Herodotus led nearly a million of men in his expeditions. He was the most noted of ancient warriors until Cyrus the Persian arose, and was nearly contemporaneous with Moses. The Trojan war is supposed to have taken place during the period when the Israelites were subject to the Ammonites; and about the time that the Philistines were defeated by David, the Greeks were forced by war to found colonies in Asia Minor.

After authentic history begins, war is the main subject with which it has to deal; and for three thousand years history is simply the record of the feats of warriors and generals, of their conquests and defeats, of the rise and fall of kingdoms and cities, of the growth or decline of military virtues. No arts of civilization have preserved nations from the sword of the conqueror, and war has been both the amusement and the business of kings. From the earliest ages, the most valued laurels have been bestowed for success in war, and military fame has eclipsed all other glories. The cry of the mourner has been unheeded in the blaze of conquest; even the aspirations of the poet and the labors of the artist have been as nought, except to celebrate the achievements of heroes.

It is interesting then to inquire how far the ancients advanced in the arts of war, which include military weapons, movements, the structure of camps, the discipline of armies, the construction of ships and of military engines, and the concentration and management of forces under a single man. What was that mighty machinery by which nations were subdued, or rose to greatness on the ruin of States and Empires? The conquests of Rameses, of David, of Nebuchadnezzar, of Cyrus, of Alexander, of Hannibal, of Caesar, and other heroes are still the subjects of contemplation among statesmen and schoolboys. The exploits of heroes are the pith of history.

The art of war must have made great progress in the infancy of civilization, when bodily energies were most highly valued, when men were fierce, hardy, strong, and uncorrupted by luxury; when mere physical forces gave law alike to the rich and the poor, to the learned and the ignorant; and when the avenue to power led across the field of battle.

We must go to Egypt for the earliest development of art and science in all departments; and so far as the art of war consists in the organization of physical forces for conquest or defence, under the direction of a single man, it was in Egypt that this was first accomplished, about seventeen hundred years before Christ, as chronologists think, by Rameses the Great.

This monarch, according to Wilkinson, the greatest and most ambitious of the Egyptian kings, to whom the Greeks gave the name of Sesostris, showed great ability in collecting together large bodies of his subjects, and controlling them by a rigid military discipline. He accustomed them to heat and cold, hunger and thirst, fatigue, and exposure to danger. With bodies thus rendered vigorous by labor and discipline, they were fitted for distant expeditions. Rameses first subdued the Arabians and Libyans, and annexed them to the Egyptian monarchy. While he inured his subjects to fatigue and danger, he was careful to win their affections by acts of munificence and clemency. He then made his preparations for the conquest of the known world, and collected an army, according to Diodorus Siculus, of six hundred thousand infantry, twenty-four thousand cavalry, and twenty-seven thousand war-chariots. It is difficult to understand how a small country like Egypt could furnish such an immense force. If the account of the historian be not exaggerated, Rameses must have enrolled the conquered Libyans and Arabians and other nations among his soldiers. He subjected his army to a stern discipline and an uncomplaining obedience to orders,--the first principle in the science of war, which no successful general in the world's history has ever disregarded, from Alexander to Napoleon. With this powerful army his march was irresistible. Ethiopia was first subdued, and an exaction made from the conquered of a tribute of gold, ivory, and ebony. In those ancient times a conquering army did not resettle or colonize the territories it had subdued, but was contented with overrunning the country and exacting tribute from the people. Such was the nature of the Babylonian and Persian conquests. After overrunning Ethiopia and some other countries near the Straits of Babelmandeb, the conqueror proceeded to India, which he overran beyond the Ganges, and ascended the high table-land of Central Asia; then proceeding westward, he entered Europe, nor halted in his devastating career until he reached Thrace. From thence he marched to Asia Minor, conquering as he went, and invaded Assyria, seating himself on the throne of Ninus and Semiramis. Then, laden with booty from the Eastern world, he returned to Egypt after an absence of thirty years and consolidated his empire, building those vast structures at Thebes, which for magnitude have never been surpassed. Thus was Egypt enriched with the spoil of nations, and made formidable for a thousand years. Rameses was the last of the Pharaohs who pursued the phantom of military renown, or sought glory in distant expeditions.

We are in ignorance as to the details of the conquests and the generals who served under Rameses. There is doubtless some exaggeration in the statements of the Greek historian, but there is no doubt that this monarch was among the first of the great conquerors to establish a regular army, and to provide a fleet to co-operate with his land forces.

The strength of the Egyptian army consisted mainly in archers. They fought either on foot or in chariots; cavalry was not much relied upon, although mention is frequently made of horsemen as well as of chariots. The Egyptian infantry was divided into regiments, and Wilkinson tells us that they were named according to the arms they bore,--as "bowmen, spearmen, swordsmen, clubmen, slingers." These regiments were divided into battalions and companies, commanded by their captains. The infantry, heavily armed with spears and shields, formed a phalanx almost impenetrable of twelve men deep, who marched with great regularity. Each company had its standard-bearer, who was an officer of approved valor; the royal standards were carried by the royal princes or by persons of the royal household. The troops were summoned by the sound of trumpet, and also by the drum, both used from the earliest period. The offensive weapons were the bow, the spear, the javelin, the sword, the club, or mace, and the battle-axe. The chief defensive weapon was the shield, about three feet in length, covered with bull's hide, having the hair outward and studded with nails. The shape of the bow was not essentially different from that used in Europe in the Middle Ages, being about five feet and a half long, round, and tapering at the ends; the bowstring was of hide or catgut. The arrows of the archers averaged about thirty inches in length, and were made of wood or reeds, tipped with a metal point, or flint, and winged with feathers. Each bowman was furnished with a plentiful supply of arrows. When arrows were exhausted, the bowman fought with swords and battle-axes; his defensive armor was confined chiefly to the helmet and a sort of quilted coat. The spear was of wood, with a metal head, was about five or six feet in length, and used for thrusting. The javelin was lighter, for throwing. The sling was a thong of plaited leather, broad in the middle, with a loop at the end. The sword was straight and short, between two and three feet in length, with a double edge, tapering to a sharp point, and used for either cut or thrust; the handle was frequently inlaid with precious stones. The metal used in the manufacture of swords and spear-heads was bronze, hardened by a process unknown to us. The battle-axe had a handle about two-and a-half feet in length, and was less ornamented than other weapons. The cuirass, or coat of armor, was made of horizontal rows of metal plate, about an inch in breadth, well secured together by bronze pieces. The Egyptian chariot held two persons,--the charioteer, and the warrior armed with his bow-and-arrow and wearing a cuirass, or coat of mail. The warrior carried also other weapons for close encounter, when he should descend from his chariot to fight on foot. The chariot was of wood, the body of which was light, strengthened with metal; the pole was inserted in the axle; the two wheels usually had six spokes, but sometimes only four; the wheel revolved on the axle, and was secured by a lynch-pin. The leathern harness and housings were simple, and the bridles, or reins, were nearly the same as are now in use.

"The Egyptian chariot corps, like the infantry," says Wilkinson, "were divided into light and heavy troops, both armed with bows,--the former chiefly employed in harassing the enemy with missiles; the latter called upon to break through opposing masses of infantry." The infantry, when employed in the assault of fortified towns, were provided with shields, under cover of which they made their approaches to the place to be attacked. In their attack they advanced under cover of the arrows of the bowmen, and instantly applied the scaling-ladder to the ramparts. The testudo, a wooden shelter, was also used, large enough to contain several men. The battering-ram and movable towers resembled those of the Romans a thousand years later.
