He perceived that the time was come for turning a new leaf in the history of war. With such numbers of troops as the infant Republic could afford him, he saw that no considerable advantages could be obtained against the vast and highly-disciplined armies of Austria and her allies, unless the established rules and etiquettes of strategy were abandoned. It was only by such rapidity of motion as should utterly transcend the suspicion of his adversaries, that he could hope to concentrate the whole pith and energy of a small force upon some one point of a much greater force opposed to it, and thus rob them (according to his own favourite phrase) of the victory. To effect such rapid marches, it was necessary that the soldiery should make up their minds to consider tents and baggage as idle luxuries; and that, instead of a long and complicated chain of reserves and stores, they should dare to rely wholly for the means of subsistence on the resources of the countries into which their leader might conduct them. They must be contented to conquer at whatever hazard; to consider no sacrifices or hardships as worthy of a thought. The risk of destroying the character and discipline of the men, by accustoming them to pillage, was obvious. Buonaparte trusted to victory, the high natural spirit of the nation, and the influence of his own genius, for the means of avoiding this danger; and many years, it must be admitted, elapsed, before he found much reason personally to repent of the system which he adopted. Against the enemies of the Republic its success was splendid, even beyond his hopes.
The objects of the approaching expedition were three: first, to compel the King of Sardinia, who had already lost Savoy and Nice, but still maintained a powerful army on the frontiers of Piedmont, to abandon the alliance of Austria: secondly, to compel the Emperor, by a bold invasion of Lombardy, to make such exertions in that quarter as might weaken those armies which had so long hovered on the Rhine; and, if possible, to stir up the Italian subjects of that crown to adopt the revolutionary system and emancipate themselves for ever from its yoke. The third object, though more distant, was not less important. The influence of the Romish Church was considered by the Directory as the chief, though secret, support of the cause of royalism within their own territory; and to reduce the Vatican into insignificance, or at least force it to submission and quiescence, appeared indispensable to the internal tranquillity of France. The Revolutionary Government, besides this general cause of hatred and suspicion, had a distinct injury to avenge. Their agent, Basseville, had three years before been assassinated in a popular tumult at Rome: the Papal troops had not interfered to protect him, nor the Pope to punish his murderers; and the haughty Republic considered this as an insult which could only be washed out with a sea of blood.
