On the eve of active operations in the first months of 1800 the military situation was as follows: The Italian line stretched from Genoa around by Savona to the Col di Tenda. On it were thirty thousand men, under Masséna, while ten thousand more guarded the passes of the Alps. Confronting it was an Austrian force of eighty thousand men, under Melas, a general of the old formal school, hampered by tradition and by the machinery of the Aulic Council in Vienna. In Tuscany, in the Papal States, and in Piedmont were twenty thousand Austrian soldiers in garrison. On the Rhine stood Moreau, with a hundred and twenty thousand men, facing a less able antagonist than Melas in the person of Kray, whose army was about equal in number to his own. The Austrian lines stretched from the falls of the Rhine northward by their headquarters at Donaueschingen to Kinzig. The greatest of the Austrian generals, the Archduke Charles, was not in the field. A sensitive epileptic, he had been wounded by the incessant and meddling interference of the Vienna bureaucrats, and had temporarily withdrawn from service. The plan of Francis and his ministry was to drive back Masséna's inferior force; then, with the aid of the English fleet, which arrived in March, under Keith, to reduce Genoa, where Masséna was sure to make a stand; then to cross the Var, and increase the numerical superiority of the Austrians still further by a union with the royalists of Provence, who were organizing under Pichegru, just escaped from Guiana; and finally to carry the war into the heart of France, while Kray held Moreau in check.

By an article of the new French constitution the First Consul might not be also commander-in-chief of the forces; but, as he said to Miot de Melito, nothing forbade him to be present with the army. Nevertheless, his military greatness was now for the first time to display its stupendous proportions. Hitherto, superb as had been his achievements, they had been won as a subordinate carrying out one part of a large plan, and securing prominence for his own ideas only by disregarding those of nominal superiors. Now he had charge of a great war in its entirety. There was but one obstacle—Moreau's ability and jealousy. With the superiority of true greatness, Bonaparte at once took in the military situation, and, disregarding all the vexing details which would pass for essentials with men of less ability, analyzed it into its large and simple elements. If Kray were beaten, the French army could reach Vienna, and dictate peace before Melas could produce an effect in Italy. His plan, therefore, was to unite near Schaffhausen the various portions of the reserve army which he had quietly been organizing, and, covered by the Rhine, to effect a junction with Moreau; then by overwhelming superiority of numbers to turn Kray's left flank, cut off his connections, and, taking his army in the rear, either capture or annihilate it. Moreover, a detachment of this victorious force could then cross the easy lower passes of the Alps, and attack the Austrian army in Italy from the rear, even if in the interval that force should have been victorious. In this one great combination lies the proof of its author's genius. Its five great strategic principles are these: one line of operation, with one offensive; the massing of the army as the first aim; the line of operation on the enemy's flank verging toward his rear; the surrounding of the enemy's wing so as to jeopardize his connections; and lastly, the defense of your own connections. Standing in sharpest contrast with those of his great predecessor Frederick, these principles have not yet been overthrown even by modern science, nor by the revolutionary change which has taken place in the material of war and in the number of men engaged in modern conflicts.
But the idea was too great for the conditions. Moreau would not serve as second in command, and Bonaparte was perfectly aware that he himself was not yet sufficiently firm in his political seat to alienate a rival so influential. In fact, on March sixteenth, he wrote a private letter to Moreau, in which he said: "General Dessoles will tell you that no one is more interested than I am in your personal glory and in your happiness. The English are embarking in force. What do they want? I am to-day a sort of manikin which has lost its liberty and its happiness. Greatness is fine, but only in memory and in imagination. I envy your happy lot. You are going to do great things with brave men. I would gladly exchange my consular purple for the epaulets of a brigade commander under your orders." All the First Consul's military conceptions had to be carefully propounded; that for a campaign in central Germany was not carried out until several years later. Moreau, conscious of his own powers, would not even accept Bonaparte's suggestions for conducting the passage of the Rhine. He was therefore left perforce to act independently except for instructions from Paris that he should take the offensive at once, and drive the enemy into Bavaria behind the Lech, so as to intercept his direct communication with Milan by way of Lake Constance and the Grisons. Lecourbe, with twenty thousand men, was to watch the higher Alpine passes. The dangerous rival was then left entirely to himself, and the destination of the reserve army was changed to Italy. This, of course, was done in order that such success as Moreau would certainly have won with its aid might not endanger the political situation in Paris. He must not be permitted to retrieve a reputation sullied both by his suspected connection with Pichegru's conspiracy, and by his participation, contrary to lifelong professions, in the revolution of Brumaire.
Early in March the existence of the hitherto hidden army was revealed by an order for its advance toward Zurich to prepare for crossing the Alps. Switzerland, having fallen into French hands through Masséna's operations of the previous year, and being therefore no longer neutral, its territory was open for use in offensive operations against the foe. Masséna had received his first instructions a few days earlier. They were to concentrate the Army of Italy in order to defend Genoa and the entrance to France. Melas would surely follow the well-worn Austrian plan of advancing in three columns for a concentric attack. The French general was to avoid two, and meet the third with all his strength. In April, however, he was informed of the new combination, and told to stand on the defensive until the reserve army had crossed the Alps. "The art of war," Bonaparte always said, "is to gain time when your strength is inferior." This Masséna, with brilliant capacity, undertook to do when, on April sixth, the brave and veteran Melas attacked him with sixty thousand men. But in spite of repeated successes against superior numbers, before the end of the month active resistance became impossible, and the whole French center was compelled to withdraw on April twenty-first behind the walls of Genoa, the situation of which now became precarious, for it was blockaded by the English fleet, and provisions were growing very scanty, not more than sufficient stores for a month being available. Suchet, with the left of Masséna's army, ten thousand strong, retreated along the coast, pursued by Melas with twenty-eight thousand, until on May fourteenth the former crossed the Var. Ott, with twenty-four thousand men, was left to beleaguer Genoa, in which Masséna held out until June fourth—a siege considered one of the most stubborn in history.
Such had been the wretched management of the previous year in the department of war at Paris that Moreau's force was not properly supplied in any particular, and he would not move until a month after the time arranged. It was not until April twenty-fifth, after an urgent request from Bonaparte, that he ventured to carry out his own cautious plan for the passage of the Rhine in four divisions instead of in one united body, as the First Consul had suggested. Less was risked, and probably less was won; but the complicated movement was prosperous. Making a feint as if to occupy the Black Forest, he completely misled Kray as to his real intentions, and induced him to abandon his strong position at Donaueschingen. By a series of clever countermarches, in which the Rhine was crossed and recrossed several times by various French corps, the whole of Moreau's command was finally united beyond the Black Forest, having successfully outflanked not only that dangerous mountain-range, but also the enemy, which was still occupied in guarding its eastern exits.
The movement was brought to a fortunate conclusion by the French advance, before which the Austrians withdrew to secure a position. In the last days of April Moreau found himself with only twenty-five thousand men facing the mass of the Austrians under Kray at Engen. In the rear, on his left, but beyond reach, was a division of his own army under Saint-Cyr. On May second, expecting their speedy arrival, he joined battle with his inadequate force. The reinforcements did not arrive; but after a desperate fight, with serious loss, he defeated the enemy. Next day Saint-Cyr came in, and the Austrians, having learned that Stockach with its abundant stores had fallen into the hands of the French division under Lecourbe, withdrew northeastward toward the Danube. Moreau's success was unqualified. Kray could no longer retreat toward the Tyrol by Switzerland and the Vorarlberg; he had also lost a large supply of munitions most precious to their captors, besides five thousand prisoners and three thousand killed.
Nevertheless, he was still undismayed, and two days later made a stand at Messkirch. After an embittered and sanguinary conflict on May fifth he was again defeated. The victory of Moreau would have been overwhelming but for a second inexplicable failure of Saint-Cyr to bring his division into action. Investigation revealed that while that division general had displayed no zeal and had evinced no good will in the interpretation of orders, he had strictly obeyed their letter. His laxity was therefore overlooked. It was soon found that the Austrians were again gathered to defend their depots at Biberach. This time Saint-Cyr was ardent, and with conspicuous fire he led his inferior numbers against the enemy's center, driving them from their position. Still aglow with victory, he then called in a second division under Richepanse, and attacking again the main body of the enemy's army, which was drawn up on the slopes of the Mettenberg, dislodged them from that position also. Two days later Lecourbe captured Memmingen with eighteen hundred prisoners, and on the tenth the Austrians withdrew to make a determined stand on a fortified camp at Ulm. It is probable that in two days Moreau would have driven them from that position if his force had been left intact; but Carnot had come in person to ask for the detachment of Lecourbe's corps to serve in Italy, and a request from such a man could not well be denied.
