In truth, the position that youth is necessary to success in war is not sustained by military history. It may he no drawback to a soldier's excellence that he is young, but it is equally true that an old man may possess every quality that is necessary in a soldier who would serve his country well and win immortal fame for himself. The best of the Greek commanders were men in advanced life, with a few exceptions. The precise age of Miltiades at Marathon is unproven; but as he had become a noted character almost thirty years before the date of that most memorable of battles, he must have been old when he fought and won it. Even Alcibiades, with whom is associated the idea of youth through his whole career, as if Time had stood still in his behalf, did not have a great command until he was approaching to middle age; and it was not until some years more had expired that he won victories for the Athenians. The date of the birth of Epaminondasthe best public man of all antiquity, and the best soldier of Greececannot be fixed; but we find him a middle-aged man when first he appears on that stage on which he performed so pure and brilliant a part through seventeen eventful years. Eight years after he first came forward he won the Battle of Leuctra, which shattered the Spartan supremacy forever, and was the most perfect specimen of scientific fighting that is to be found in classical history, and which some of the greatest of modern commanders have been proud merely to imitate. After that action, but not immediately after it, he invaded the Peloponnesus, and led his forces to the vicinity of Sparta, and then effected a revolution that bridled that power perpetually. Nine years after Leuctra he won the Battle of Mantinea, dying on the field. He must then have been an old man, but the last of his campaigns was a miracle of military skill in all respects; and the effect of his death was the greatest that ever followed the fall of a general on a victorious field, actually turning victory into defeat. The Spartan king, Agesilaus II., who was a not unworthy antagonist of the great Theban, was an old man, and was over seventy when he saved Sparta solely through his skill as a soldier and his energy as a statesman. As a rule, the Greeks, the most intellectual of all races, were averse to the employment of young men in high offices. The Spartan Brasidas, if it be true that he fell in the flower of his age, as the historian asserts, may have been a young man at the beginning of the Peloponnesian War, in which he was eminently distinguished; but it was his good fortune to be singularly favored by circumstances on more than one occasion, and his whole career was eminently exceptional to the general current of Hellenic life.
The Romans, though not braver than the Greeks, were more fortunate in their military career than the stayers of the march of Persia. Like the Greeks, they had but few young generals of much reputation. Most of their conquests, and, indeed, the salvation of their country, were the work of old leaders. The grand crisis of Rome was in the years that followed the arrival of Hannibal in Italy; and the two men who did most to baffle the invader were Fabius and Marcellus, who were called, respectively, Rome's shield and sword. They were both old men, though Marcellus may have been looked upon as young in comparison with Fabius, who was upward of seventy, and who, eight years after his memorable pro-dictatorship, retook Tarentum and baffled Hannibal. The old Lingerer was, at eighty, too clever, slow as they thought him at Rome, to be "taken in" by Hannibal, who had prepared a nice trap for him, into which he would not walk. Marcellus was about fifty-two when he was pitted against the victor of Cannæ, and he met him on various occasions, and sometimes with striking success. At the age of fifty-six he took Syracuse, after one of the most memorable of sieges, in which he had Archimedes for an opponent. At sixty he was killed in a skirmish, leaving the most brilliant military name of the republican times, so highly are valor and energy rated, though in the higher qualities of generalship he was inferior to men whose names are hardly known. Undoubtedly, Mommsen is right when he says that Rome was saved by the Roman system, and not by the labors of this man or that; but it is something for a country to have men who know how to work under its system, and in accordance with its requirements; and such men were Fabius and Marcellus, the latter old enough to be Hannibal's father, while the former was the contemporary of his grandfather.
The turning point in the Second Punic War was the siege of Capua by the Romans. That siege Hannibal sought by all means in his power to raise, well knowing, that, if the Campanian city should fall, he could never hope to become master of Italy. He marched to Rome in the expectation of compelling the besiegers to hasten to its defence; but without effect. Two old Romans commanded the beleaguering army, and while one of them, Q. Fulvius, hastened home with a small force, the other, Appius Claudius, carried on the siege. Hannibal had to retreat, and Capua fell, the effect of the tenacity with which ancient generals held on to their prey. Had they been less firm, the course of history would have been changed. At a later period of the war, Rome was saved from great danger, if not from destruction, by the victory of the Metaurus, won by M. Livius Salinator and C. Claudius Nero. Nero was an elderly man, having been conspicuous for some years, and the consular age being forty. His colleague was a very old man, having been consul before the war began, and having long lived in retirement, because he had been unjustly treated. The Romans now forced him to take office, against his wish, though his actions and his language were of the most insulting character. A great union of parties had taken place, for Hasdrubal was marching to Italy, for the purpose of effecting a junction with his brother Hannibal, and it was felt that nothing short of perfect union could save the State. The State was saved, the two old consuls acting together, and defeating and slaying Hasdrubal in the last great battle of the war that was fought in Italy. The old fogies were too much for their foe, a much younger man than either of them, and a soldier of high reputation.
It must be admitted, however, that the Second Punic War is fairly quotable by those who insist upon the superiority of youthful generals over old ones, for the two greatest men who appeared in it were young leaders,Hannibal, and Publius Cornelius Scipio, the first Africanus. No man has ever exceeded Hannibal in genius for war. He was one of the greatest statesmen that ever lived, and he was so because he was the greatest of soldiers. He might have won pitched battles as a mere general, but it was his statesmanship that enabled him to contend for sixteen years against Rome, in Italy, though Rome was aided by Carthaginian copperheads. But, though a young general, Hannibal was an old soldier when he led his army from the Ebro to the Trebia, as the avenging agent of his country's gods. His military as well as his moral training began in childhood; and when his father, Hamilcar Barcas,2 was killed, Hannibal, though but eighteen, was of established reputation in the Carthaginian service. Eight years later he took the place which his father and brother-in-law had held, called to it by the voice of the army. During those eight years he had been constantly employed, and he brought to the command an amount and variety of experience such as it has seldom been the lot of even old generals to acquire. Years brought no decay to his faculties, and we have the word of his successful foe, that at Zama, when he was forty-five, he showed as much skill as he had displayed at Cannæ, when he was but thirty-one. Long afterward, when an exile in the East, his powers of mind shine as brightly as they did when he crossed the Pyrenees and the Alps to fulfil his oath. Scipio, too, though in a far less degree than Hannibal, was an old soldier. He had been often employed, and was present at Cannæ, before he obtained that proconsular command in Spain which was the worthy foundation of his fortunes. The four years that he served in that country, and his subsequent services in Africa, qualified him to meet Hannibal, whose junior he was by thirteen years. That he was Hannibal's superior, because he defeated him at Zama, with the aid of Masinissa, no more follows than that Wellington was Napoleon's superior, because, with the aid of Blücher, he defeated him at Waterloo. It would not be more difficult to account for the loss of the African field than it is to account for the loss of the Flemish field, by the superior genius. The elder Africanus is the most exceptional character in all history, and it is impossible to place him. He seems never to have been young, and we cannot associate the idea of age with him, even when he is dying at Liternum at upwards of fifty. He was a man at seventeen, when first he steps boldly out on the historic page, and there is no apparent change in him when we find him leading great armies, and creating a new policy for the redemption of Italy from the evils of war. He was intended to be a king, but he was born two centuries too early to be of any use to his country in accordance with his genius, out of the field. Such a man is not to be judged as a mere soldier, and we were inclined not to range him on the side of youthful generals; but we will be generous, and, in consideration of his years, permit him to be claimed by those who insist that war is the business of youth.
