The first stage of civilisation is less favourable to success in war. As a nation advances in the peaceful arts, and the character of the soldier begins to be less familiarly united with that of the citizen, this system of natural tactics falls out of practice; and when foreign invasion, or civil broils, call the inhabitants to arms, they have no idea save that of finding out the enemy, rushing upon him, and committing the event to superior strength, bravery, or numbers. An example may be seen in the great Civil War of England, where men fought on both sides, in almost every county of the kingdom, without any combination, or exact idea of uniting in mutual support, or manœuvring so as to form their insulated bands into an army of preponderating force. At least, what was attempted for that purpose must have been on the rudest plan possible, where, even in actual fight, that part of an army which obtained any advantage, pursued it as far as they could, instead of using their success for the support of their companions; so that the main body was often defeated when a victorious wing was in pursuit of those whom their first onset had broken.
But – as war becomes a profession, and a subject of deep study – it is gradually discovered, that the principles of tactics depend upon mathematical and arithmetical science; and that the commander will be victorious who can assemble the greatest number of forces upon the same point at the same moment, notwithstanding an inferiority of numbers to the enemy when the general force is computed on both sides. No man ever possessed in a greater degree than Buonaparte, the power of calculation and combination necessary for directing such decisive manœuvres. It constituted, indeed, his secret– as it was for some time called – and that secret consisted in an imagination fertile in expedients which would never have occurred to others; clearness and precision in forming his plans; a mode of directing with certainty the separate moving columns which were to execute them, by arranging so, that each division should arrive on the destined position at the exact time when their service was necessary; and above all, in the knowledge which enabled such a master-spirit to choose the most fitting subordinate implements, to attach them to his person, and, by explaining to them so much of his plan as it was necessary each should execute, to secure the exertion of their utmost ability in carrying it into effect.
Thus, not only were his manœuvres, however daring, executed with a precision which warlike operations had not attained before his time; but they were also performed with a celerity which gave them almost always the effect of surprise. Napoleon was like lightning in the eyes of his enemies; and when repeated experience had taught them to expect this portentous rapidity of movement, it sometimes induced his opponents to wait, in a dubious and hesitating posture, for attacks, which, with less apprehension of their antagonist, they would have thought it more prudent to frustrate and to anticipate.
Great sacrifices were necessary to enable the French troops to move with that degree of celerity which Buonaparte's combinations required. He made no allowance for impediments or unexpected obstacles; the time which he had calculated for execution of manœuvres prescribed, was on no account to be exceeded – every sacrifice was to be made of baggage, stragglers, even artillery, rather than the column should arrive too late at the point of its destination. Hence, all that had hitherto been considered as essential not only to the health, but to the very existence of an army, was in a great measure dispensed with in the French service; and, for the first time, troops were seen to take the field without tents, without camp-equipage, without magazines of provisions, without military hospitals; – the soldiers eating as they could, sleeping where they could, dying where they could; but still advancing, still combating, and still victorious.
It is true that the abandonment of every object, save success in the field, augmented frightfully all the usual horrors of war. The soldier, with arms in his hands, and wanting bread, became a marauder in self-defence; and, in supplying his wants by rapine, did mischief to the inhabitants, in a degree infinitely beyond the benefit he himself received; for it may be said of military requisition, as truly as of despotism, that it resembles the proceedings of a savage, who cuts down a tree to come at the fruit. Still, though purchased at a high rate, that advantage was gained by this rapid system of tactics, which in a slower progress, during which the soldier was regularly maintained, and kept under the restraint of discipline, might have been rendered doubtful. It wasted the army through disease, fatigue, and all the consequences of want and toil; but still the victory was attained, and that was enough to make the survivors forget their hardships, and to draw forth new recruits to replace the fallen. Patient of labours, light of heart and temper, and elated by success beyond all painful recollections, the French soldiers were the very men calculated to execute this desperate species of service under a chief, who, their sagacity soon discovered, was sure to lead to victory all those who could sustain the hardships by which it was to be won.
The character of the mountainous countries, among which he was, for the first time, to exercise his system, was highly favourable to Buonaparte's views. Presenting many lines and defensible positions, it induced the Austrian generals to become stationary, and occupy a considerable extent of ground, according to their old system of tactics. But though abounding in such positions as might at first sight seem absolutely impregnable, and were too often trusted to as such, the mountains also exhibited to the sagacious eye of a great captain, gorges, defiles, and difficult and unsuspected points of access, by which he could turn the positions that appeared in front so formidable; and, by threatening them on the flank and on the rear, compel the enemy to a battle at disadvantage, or to a retreat with loss.
The forces which Buonaparte had under his command were between fifty and sixty thousand good troops, having, many of them, been brought from the Spanish campaign, in consequence of the peace with that country; but very indifferently provided with clothing, and suffering from the hardships they had endured in those mountainous, barren, and cold regions.88 The cavalry, in particular, were in very poor order; but the nature of their new field of action not admitting of their being much employed, rendered this of less consequence. The misery of the French army, until these Alpine campaigns were victoriously closed by the armistice of Cherasco, could, according to Buonaparte's authority,89 scarce bear description. The officers for several years had received no more than eight livres a-month (twenty pence sterling a-week) in name of pay, and staff-officers had not amongst them a single horse. Berthier preserved, as a curiosity, an order of the day, dated Albenga, directing an advance of four Louis d'or to every general of division, to enable them to enter on the campaign.90 Among the generals to whom this paltry supply was rendered acceptable by their wants, were, or might have been, many whose names became afterwards the praise and dread of war.91 Augereau, Massena,92 Serrurier, Joubert, Lasnes, and Murat, all generals of the first consideration, served under Buonaparte in his first Italian campaign.
The position of the French army had repeatedly varied since October 1795, after the skirmish at Cairo. At that time the extreme left of the line, which extended from south to north, rested upon the Col d'Argentine, and communicated with the higher Alps – the centre was on the Col di Tende and Mount Bertrand – the left occupied the heights of Saint Bertrand, Saint Jacques, and other ridges running in the same direction, which terminated on the Mediterranean shore, near Finale.
The Austrians, strongly reinforced, attacked this line, and carried the heights of Mont Saint Jacques; and Kellermann, after a vain attempt to regain that point of his position, retreated to the line of defence more westward, which rests on Borghetto. Kellermann, an active and good brigade officer, but without sufficient talent to act as commander-in-chief, was superseded, and Scherer was placed in command of the army of Italy. He risked a battle with the Austrians near Loana, in which the talents of Massena and Augereau were conspicuous; and by the victory which ensued, the French regained the line of Saint Jacques and Finale, which Kellermann had been forced to abandon; so that in a general point of view, the relative position of the two opposed armies was not very different from that in which they had been left by Buonaparte.93
