Alfred Thayer Mahan - The Influence of Sea Power upon the French Revolution and Empire 1793-1812, Vol II

On the 6th of May the first consul left Paris, having delayed to the last moment in order to keep up the illusions of the Austrian commander-in-chief in Italy. The crossing of the St. Bernard began on the 15th, and on the 20th the whole army had passed. On the 26th it issued in the plains of Piedmont; whence Bonaparte turned to the eastward, to insure his great object of throwing his force across the enemy's communications and taking from him all hope of regaining them without a battle. On the first of June he entered Milan.

Meanwhile Masséna's army, a prey to horrible famine, prolonged in Genoa a resistance which greatly contributed to the false position of the Austrians. Of these, twenty-five thousand were before Nice, thirty thousand before Genoa. Twenty thousand more had been lost by casualties since the campaign opened. Unwilling to relinquish his gains, Mélas waited too long to concentrate his scattered troops; and when at last he sent the necessary orders, Masséna was treating to evacuate Genoa. The Austrian officer on the spot, unwilling to lose the prize, postponed compliance until it was secured,—a delay fraught with serious results. On the 5th Genoa was given up, and the besiegers, leaving a garrison in the place, marched to join the commander-in-chief, who was gathering his forces around Alessandria. Meanwhile Bonaparte had crossed to the south side of the Po with half his army. On the 14th of June was fought the battle of Marengo. Anxious lest the foe might give him the slip, the first consul had spread his troops too widely; and the first events of the day were so far in favor of the Austrians that Mélas, who was seventy-six years old, left the field at two in the afternoon, certain of victory, to seek repose. An hour later the opportune arrival of General Desaix turned the scales, and Bonaparte remained conqueror on the ground, standing across the enemy's line of retreat. The following day Mélas signed a convention abandoning all northern Italy, as far as the Mincio, behind which the Austrians were to withdraw. All the fortified places were given up to France, including the hardly won Genoa. While awaiting the Emperor's answer to propositions of peace, sent by the First Consul, there was to be in Italy a suspension of arms, during which neither army should send detachments to Germany. On the 2d of July Bonaparte re-entered Paris in triumph, after an absence of less than two months.

Meantime Moreau, after learning the successful crossing of the St. Bernard, had resumed the offensive. Moving to the eastward, he crossed the Danube below Ulm with part of his force on the 19th of June, threatening Kray's communications with Bohemia. A partial encounter on that day left five thousand prisoners in the hands of the French, who maintained the position they had gained. The same night Kray evacuated Ulm, moving rapidly off by a road to the northward and so effecting his escape. Moreau, unable to intercept, followed for some distance and then stopped a pursuit which promised small results. He was still ignorant of the battle of Marengo, of which the Austrians now had news; and the latter, while concealing the victory, announced to him the suspension of arms, and suggested a similar arrangement in Germany. Convinced that events favorable to France lay behind this proposition, Moreau would come to no agreement; but on the contrary decided at once to secure for his victorious army the most advantageous conditions with which to enter upon negotiations. Closely investing the important fortresses of Ulm and Ingolstadt on the Danube, with part of his force, he recrossed the river with the remainder and advanced into Bavaria. On the 28th of June he entered Munich; and near there was signed on the 15th of July an armistice, closely corresponding with that concluded by Bonaparte in Italy just one month before. The two belligerents retired behind appointed lines, not again to engage in hostilities without twelve days' notice. During this suspension of arms the blockaded Austrian fortresses should receive every fortnight provisions proportioned to their consumption, so that in case of renewed operations they would be in the same condition as when the truce began. The two great French armies were now encamped in the fertile plains of Italy and Germany, living in quiet off districts external to France, which was thus relieved of the larger part of their expense.

The effect of this short and brilliant campaign of unbroken French successes was to dispose to peace both members of the coalition. Neither, however, was yet reduced to negotiate apart from its ally. On the very day the news of Marengo was received at Vienna, but before the last reverses in Germany, Austria had renewed her engagements with Great Britain, both powers stipulating not to treat singly. The first consul, on the other hand, was distinctly opposed to joint discussions, his constant policy in the cabinet as in the field being to separate his opponents. As Austria's great need was to gain time, she sent to Paris an envoy empowered to exchange views with the French government but to conclude nothing. The emperor also intimated his wish for a general pacification, and on the 9th of August the British minister at Vienna notified to that court the willingness of his own to enter into negotiations for a general peace.

With this began an encounter of wits, in which Bonaparte showed himself as astute at a bargain as he was wily in the field. Austria, if not given too much time, was at his mercy; but Great Britain held over him a like advantage in her control of the sea, which was strangling the colonial empire he passionately wished to restore. Haïti had escaped from all but nominal control; Martinique, the gem of the Antilles, was in British hands; Malta and Egypt, the trophies of his own enterprise, were slowly but surely expiring. For these he too needed time; for with it there was good prospect of soon playing a card which should reverse, or at least seriously modify, the state of the game, by bringing Russia and the Baltic navies into the combination against Great Britain. In this support, and in the extremity to which he might reduce Austria, lay his only chances to check the great opponent of France; for, while almost supreme on the Continent, he could not from the coast project his power beyond the range of a cannon's ball. His correspondence throughout this period abounds with instructions and exhortations to fit out the fleets, to take the sea, to relieve Malta and Egypt, to seize Sardinia by an expedition from Corsica, and Mahon by a squadron from Brest. All fell fruitless before the exhaustion of French sea power, as did also his plan for an extensive cruise on a grand scale against British commerce in many quarters of the world. "I see with regret," wrote he to the minister of Marine, "that the armament of the fleet has been sacrificed to that of a great number of small vessels;" but in truth there was nothing else to do. His ablest admirals failed to equip ships from which every resource was cut off by the omnipresent cruisers of the enemy. "We can never take Mahon," he writes to the court of Spain, in the full swing of his triumphs after Marengo; "therefore make war on Portugal and take her provinces, so as to enter negotiations for peace with your hands as full as possible of equivalents."

The Czar Paul had joined the second coalition full of ardor against the French revolution and determined to restore the princes who had lost their thrones. He had been bitterly mortified by the reverses to his troops in 1799, and especially by the disaster to Suwarrow, for which he not unjustly blamed Austria. He was also dissatisfied to find in his allies less of zeal for unfortunate sovereigns than of desire to reduce the power of France, to whose system they attributed the misfortunes of Europe. Disappointment in his unbalanced mind turned soon to coolness and was rapidly passing to hostility. The transition was assisted, and a pretext for a breach with Great Britain afforded, by a fresh outbreak of the old dispute between her and the Baltic powers concerning the rights of neutrals. Denmark in 1799 adopted the policy of convoying her merchant vessels by ships of war, and claimed that a statement from the senior naval officer, that the cargoes contained nothing forbidden by the law of nations, exempted the convoy from the belligerent right of search. British statesmen denied that this conceded belligerent right could be nullified by any rule adopted by a neutral; to which they were the more impelled as the Danes and themselves differed radically in the definition of contraband. Danish naval officers being instructed to resist the search of their convoys, two hostile encounters took place; one in December, 1799, and the other in July, 1800. In the latter several were killed on both sides, and the Danish frigate was carried into the Downs. Seeing the threatening character of affairs, the British ministry took immediate steps to bring them to an issue. An ambassador was sent to Copenhagen supported by nine ships-of-the-line and several bomb-vessels; and on the 29th of August, barely a month after the affray, a convention was signed by which the general subject of searching ships under convoy was referred to future discussion, but Denmark consented to suspend her convoys until a definitive treaty was made. The Danish frigate was at once released.
