It is a question which has divided the learned since the revival of letters, by what pass Hannibal crossed the Alps. The general opinion of those who have studied the subject, inclines to the opinion that he crossed by the Little St Bernard; and to this opinion Arnold inclines. He admits, however, with his usual candour, that, "in some respects, also, Mont Cenis suits the description of the march better than any other pass[24]." After having visited and traversed on foot both passes, the author of this paper has no hesitation in expressing his decided conviction, that he passed by Mont Cenis. His reasons for this opinion are these:—1. It is mentioned by Polybius, that Hannibal reached the summit of the Alps on the ninth day after he had left the plains of Dauphiné. This period coincides well with what might have then been required to ascend, as the country was, on the neighbourhood of Grenoble or Echelles; while the ascent to the summit of the Little St Bernard, would not require more than half the time. 2. The narrow defile of St Jean de Maurienne, which leads from the plain of Montmelian to the foot of Mont Cenis, corresponds much more closely with the description, given both in Livy[25] and Polybius[26], of that in which the first serious engagement took place between Hannibal and the Mountaineers, two days after they had left the plains of Dauphiné, than the comparatively open valley which leads to the foot of the Little St Bernard. 3. From the summit of the Little St Bernard you can see nothing of Italy, nor any thing approaching to it; a confused sea of mountains alone meets the eye on every side. Whereas, from the southern front of the summit of Mont Cenis, not only the plains of Piedmont are distinctly visible at the opening of the lower end of the valley of Susa, which lies at your feet, but the Appenines beyond them can be seen. To settle this important point, the author made a sketch of both on the spot, on the 24th October, the very time of Hannibal's passage, which is still in his possession. How precisely does this coincide with the emphatic words of Hannibal, as recorded by Polybius, showing to them the plains around the Po, ("τα περι τον Παδον πεδια,") and, reminding them of the good disposition of the Gauls who dwelt there, he further showed them the situation of Rome itself.[27] The Appenines, beyond the plain of Piedmont, seen from Mont Cenis, might correctly be taken as the direction, at least, where Rome lay. 4. The steep and rocky declivity by which the old road formerly descended to the valley of Susa, and where the travellers descended in sledges, till Napoleon's magnificent chaussée was formed, which makes great circuit to the westward, corresponds perfectly to the famous places mentioned both by Livy and Polybius, where the path had been torn away by a recent avalanche, and the fabulous story of the vinegar was placed. This place in Mont Cenis is immediately below the summit of the pass, and may now be seen furrowed by a roaring torrent, amidst dark ledges of rock; the corresponding chasm on the southern side of the Little St Bernard is below the reach of avalanches.[28] 5. On the summit of Mont Cenis is still to be seen a "white rock" called the "Roche Blanche," which answers to the "λευκοπετρον," mentioned by Polybius, on the summit of the Alps which Hannibal crossed, whereas there is nothing like it on the Little St Bernard, at least of such magnitude as to have formed a place of night refuge to Hannibal. 6. What is perhaps most important of all, it is expressly mentioned by Polybius, that "in one day's time the chasm in the mountain sides was repaired, so that there was room for the horses and beasts of burden to descend. They were immediately conducted down, and having gained the plains, were sent away to pasture in places where no snow had fallen. * * * * * Hannibal then descended last, with all the army, and thus, on the third day, gained the plains[29]." This description of the distances tallies perfectly with the passage by Mont Cenis, for it is only half a day's journey to descend from the summit of that pass to Susa, at the head of the wide and open valley of the same name, where ample pasturage is to be found; and short day's journey more brings the traveller to the plain of Piedmont. But it is utterly irreconcilable with the idea that the Carthaginians passed by the Little St Bernard; for from its summit to the plains of Ivrea is four days' hard marching for an army, through the narrow valley of Aosta, destitute for the most part of forage. 7. This valley of Aosta is very rocky and narrow, and affords many positions where a handful of men can arrest an army; in one of which, that of Bard, a small Austrian garrison stopped Napoleon for twenty-four hours; yet Polybius and Livy concur in stating, that after he descended the mountains, the Carthaginians experienced no molestation on their way to the Insubrians, their allies, on the banks of the Po. This is inexplicable if they were struggling for three days through the narrow and rocky defiles of the valley of Aosta, but perfectly intelligible if they were traversing in half a day the broad and open valley of Susa, offering no facilities to the attacks of the mountaineers.
But if Napoleon's passage of the St Bernard can never be compared to that of Hannibal over Mont Cenis, it is impossible to deny that there is a marked and striking similarity, in some respects, between the career of the two heroes. Both rose to eminence, for the first time, by the lustre of their Italian campaigns; the most brilliant strokes of both were delivered almost on the same ground, immediately after having surmounted the Alps; both headed the forces of the democratic party in the country whose warriors they led, and were aided by it in those which they conquered; both had a thorough aversion for that party in their hearts; both continued, by their single genius, for nineteen years in hostility against a host of enemies; both were overthrown at last, in a single battle, on a distant shore, far from the scene of their former triumphs; both were driven into exile by the hatred or apprehensions of their enemies; both, after having reached the summit of glory, died alone and unbefriended in a distant land; both have left names immortal in the rolls of fame. It is no wonder that such striking similarities should have forcibly struck the imaginations of men in every land. It is remarkable that many of the greatest patriots who ever existed have died in exile, after having rendered inestimable services to their country, by which they were persecuted or betrayed. Themistocles, Hannibal, Scipio Africanus, Belisarius, Napoleon, belong to this bright band. It is not difficult to see that the cause of it is to be found in their very greatness itself. They were too powerful to be tolerated by their countrymen: they were too formidable to be endured by their enemies.
It is hard to say whether Hannibal's military capacity appeared most strongly in strategy, that is, the general direction of a campaign, or in tactics, that is, the management of troops on the field of battle. In both he was unrivalled in ancient times. His wonderful ability in strategy, and in preparing his multifarious forces for the grand enterprise for which they were destined, appears from the very outset of his military career. Devoted to the destruction of Rome from his youth upwards, and steady in the determination to over-throw that inveterate enemy to his country, he had yet the difficult and apparently hopeless task of accomplishing this by land warfare, when Carthage had no native born army in the slightest degree commensurate to its execution. To form such an army was his first object, and this he accomplished by his successes in Spain, before the second Punic War began. In the interval between the first and the second of those dire contests, he was assiduously employed in conquering, organizing, and disciplining the forces by which his great object was to be effected; and such was his capacity, that, notwithstanding the untoward issue of the first Punic War, the Carthaginians gradually regained the ascendant in the Peninsula, while his manners were so winning, that erelong he attracted all its military strength to his standard. The Roman influence was limited to the narrow and broken territory which lies between the Ebro and the Pyrenees, and forms the modern province of Catalonia, while all the rest of the Peninsula obeyed the orders of Hannibal. It was in Spain that he formed that great military force which so soon after shook to its foundation the solid fabric of Roman power; he there erected the platform on which his engines of assault were placed. When he began his triumphant march from Saguntum to attempt the conquest of Rome, after surmounting both the Pyrenees and the Alps, he was at the head of a splendid army of ninety thousand foot, and twelve thousand horse, with forty elephants; the most powerful array, if the quality and discipline of the troops is taken into account, which Europe had yet seen. Of this great force, not more than a fourth part were Carthaginian soldiers; so mightily had the military force of Hannibal increased with the prosperous issue of his Peninsular campaigns.
Had the Carthaginian general succeeded in reaching the banks of the Tiber with the half even of this force, the fate of Rome was sealed, and the glories of the Capitol were extinguished for ever. But he had innumerable difficulties to contend with—physical, warlike, and moral—before he reached the Italian plains. His march from the Ebro to the Po was a continued combat. The mountain tribes of Catalonia, celebrated in every age for their obstinate and persisting hostility, were then firm in the Roman interest. The mountain strength of the Pyrenees; the rapid currents of the Rhone; the cruel warfare, and yet more dangerous peace of the Gauls; the desperate valour of the inhabitants of the Alps; the inclemency of the weather on their snowy summits, all required to be overcome, and they thinned his ranks more than all the swords of the legions. Instead of ninety thousand foot, and twelve thousand horse, with which he broke up from Saguntum, he brought only twenty thousand infantry, and six thousand horse to the fields of Piedmont. No less than seventy-six thousand men had been lost or left to preserve the communications, since they left the Valencian plains. So slender was the force with which this great commander commenced, on its own territory, the conflict with a power which ere three years had elapsed, carried on the war with fourteen legions, numbering an hundred and seventy thousand combatants, between the auxiliaries and Roman soldiers. It is in the magnitude of this disproportion, and the extremely small amount of the reinforcement which he received from home during the next fifteen years that the war lasted, that the decisive proof of the marvellous capacity of the Carthaginian general is to be found. It is a similar disproportion which has marked the campaigns of Napoleon in Italy in 1796, and in France in 1814, with immortality.
The first necessity was to augment his numbers, and fill up the wide chasm in his ranks, by fresh enrolments in the territory in which he had entered. The warlike habits and predatory dispositions of the Cisalpine Gauls afforded the means of obtaining this necessary succour. The victory over the Roman horse on the Ticino, when the superiority of the Numidian cavalry was first decisively displayed, had an immediate effect in bringing a crowd of Gaulish recruits to his standard. The Carthaginian general was careful in his first engagement to hazard only his cavalry, in which arm he was certain of his superiority. The battle of the Trebia which followed, and which first broke the strength of the legions, excited an unbounded ferment in Lombardy, and brought the Gaulish youths in crowds, to follow the career of plunder and revenge under his victorious standards. Recruits speedily were not awanting; the only difficulty was to select from the crowds which presented themselves for enrolment. It was like the resurrection of Prussia in 1813, against the tyrannic domination of the French emperor. Winter was spent in organizing these rude auxiliaries, and reducing them to something like military discipline; and so effective was their co-operation, and so numerous the reinforcements which their zeal brought to his standard, that in the following spring he crossed the Apennines, and traversed the marshes of Volterra, at the head of nearly fifty thousand men, of whom above one half were Gaulish recruits. And when the Consul Flaminius attempted to stop him on the margin of the Thrasymene Lake, where the stream still called "Sanguinetto" murmurs among the old oaks, the children of the soil, the total defeat of his army with the loss of thirty thousand men, lost the Romans the whole north of Italy, and carried consternation to the gates of the Capitol.
After so great a victory within a few days' march of the Tiber, and no considerable army intervening to arrest the advance of the conqueror, it may seem extraordinary that Hannibal did not advance straight to the capital, and terminate the war by its destruction: still more inexplicable does it at first sight appear, that, instead of doing so, he should have turned to the left, and passing Rome, moved into the south of Italy; thus losing in a great measure his communication with Lombardy, which had hitherto proved so invaluable a nursery for his army. But it was in these very movements, more perhaps than in any others of his life, that the wisdom and judgment of this great general's conduct were conspicuous. The chief difficulty he had now to contend with in Italy was the reduction of its fortified towns. The innumerable wars which had so long prevailed in the southern parts of the Peninsula, between the Etruscans, the Romans, and the Samnites, had studded the declivities of the Apennines with castles and fortified burghs, the walls of which in great part still remain, and constitute not the least of the many interesting objects which Italy presents to the traveller. Towards the reduction of those cities, the tumultuary array of the Gauls, numerous and efficient as they were in the field, could not afford any assistance. Engines for assault or the reduction of walls they had none; funds for the maintenance of a protracted methodical warfare were not to be looked for, in their savage and half-cultivated plains. The communication with Spain by the circuitous route of the Pyrenees and Alps, had been found, by dear-bought experience, to be difficult in the extreme. It could only be opened again, by an army nearly as powerful as that which had first penetrated through it, under the guidance of his energetic will. It was in the south of the Peninsula, amidst its opulent cities and long-established civilization, that the resources for a war of sieges could alone be looked for. It was there, too, that the most direct, the shortest, and in fact the only secure channel of communication with Carthage could be opened: to a Punic as to a British army, the true base of operations is the sea, the worst possible base for that of any other military power. Beyond all question, it was to the judicious choice of the south of Italy as his stronghold, and the combined skill and policy by which he contrived to detach a large part of its rich republics, with their harbours and places of strength, from the Roman alliance, that the subsequent protraction of the war for fifteen years is to be ascribed.
Such, however, was the terror of the Roman arms, and the influence acquired by the combined steadiness and severity of their rule, that this irruption into the south of Italy was not at first attended with the desired effect. In vain he had, in all preceding engagements sent back all the prisoners from the allies without any ransom, and treated them in the most generous manner; in vain, in all preceding marches, he had cautiously abstained from pillaging or laying waste their lands. Still the Roman influence was predominant. Not one state in alliance had revolted: not one Roman colony had failed in its duty to the parent state. The Gauls alone, who now formed half his army, had repaired in crowds to his standard since he had descended from the Alps. A long season of inactivity followed, during which the Romans were too prudent to hazard a conflict with Hannibal in the field, and he was too weak in siege artillery to attempt the reduction of any of their fortified cities. But the time was not lost by that indefatigable commander, and the following passage from Arnold will both show how it was employed, and serve as a fair specimen of the style of that powerful and lamented writer:—
"Never was Hannibal's genius more displayed than during this long period of inactivity. More than half of his army consisted of Gauls, of all barbarians the most impatient and uncertain in their humour, whose fidelity, it was said, could only be secured by an ever open hand; no man was their friend any longer than he could gorge them with pay or plunder. Those of his soldiers who were not Gauls, were either Spaniards or Africans; the Spaniards were the newly conquered subjects of Carthage, strangers to her race and language, and accustomed to divide their lives between actual battle and the most listless bodily indolence; so that when one of their tribes first saw the habits of a Roman camp, and observed the centurions walking up and down before the prætorium for exercise, the Spaniards thought them mad, and ran up to guide them to their tents, thinking that he who was not fighting could do nothing but lie at his ease and enjoy himself. Even the Africans were foreigners to Carthage; they were subjects harshly governed, and had been engaged within the last twenty years in a war of extermination with their masters. Yet the long inactivity of winter quarters, trying to the discipline of the best national armies, was borne patiently by Hannibal's soldiers; there was neither desertion nor mutiny amongst them; even the fickleness of the Gauls seemed spell-bound; they remained steadily in their camp in Apulia, neither going home to their own country, nor over to the enemy. On the contrary, it seems that fresh bands of Gauls must have joined the Carthaginian army after the battle of Thrasymenus, and the retreat of the Roman army from Ariminum. For the Gauls and the Spaniards and the Africans were overpowered by the ascendancy of Hannibal's character; under his guidance they felt themselves invincible; with such a general the yoke of Carthage might seem to the Africans and Spaniards the natural dominion of superior beings; in such a champion the Gauls beheld the appointed instrument of their country's gods to lead them once more to assault the Capitol."—Vol. iii. 131-132.
It was the battle of Cannæ which first shook the fidelity of the Roman allies, and by opening to the Carthaginians the gates of Capua, gave them the command of a city in the south of Italy, second only to Rome herself in wealth and consideration. Of this great and memorable battle, when upwards of eighty thousand Romans fell, and their power was, to all appearance, irrecoverably broken, Arnold give the following interesting account:—
"The skirmishing of the light-armed troops preluded as usual to the battle; the Balearian slingers slung their stones like hail into the ranks of the Roman line, and severely wounded the consul Æmilius himself. Then the Spanish and Gaulish horse charged the Romans front to front, and maintained a standing fight with them, many leaping off their horses and fighting on foot, till the Romans, outnumbered and badly armed, without cuirasses, with light and brittle spears, and with shields made only of ox-hide, were totally routed and driven off the field. Hasdrubal, who commanded the Gauls and Spaniards, followed up his work effectually; he chased the Romans along the river, till he had almost destroyed them, and then, riding off to the right, he came up to aid the Numidians, who, after their manner, had been skirmishing indecisively with the cavalry of the Italian allies. These, on seeing the Gauls and Spaniards advancing, broke away and fled; the Numidians, most effective in pursuing a flying enemy, chased them with unweariable speed, and slaughtered them unsparingly; while Hasdrubal, to complete his signal services on this day, charged fiercely upon the rear of the Roman infantry.
