Moreau delayed to commence the campaign; his material was insufficient; Alsace and Switzerland, exhausted of resources, could not furnish the means of transport required by his movement. The First Consul urged him. "Obtain a success as soon as possible, that you may be able by a diversion in some degree to expedite the operations in Italy," he wrote to him on April 24; "every day's delay is extremely disastrous to us." On April 26, Moreau passed the Rhine at Strasburg, at Brisach, and at Basle, thus deceiving General Kray, who defended the defiles of the Black Forest, whilst the different divisions of the French army reascended and repassed the Rhine, in order to cross it afresh without difficulty at Schaffhausen. The Austrians had not yet collected their forces, dispersed by the unlooked-for movement they found themselves obliged to execute; the French corps were themselves dispersed when the battle commenced, on May 3, at Engen. After a furious struggle at several points, General Moreau achieved a splendid victory; two days later the same fortune crowned the battle of Moesskirch; the loss on both sides was great. The action was not well combined; Marshal Kray at first fell back behind the Danube; by the advice of his council of war he decided to defend the magazines at Biberach. He repassed the river, and offered battle to the corps of Gouvion St. Cyr, then hampered with Moreau, bearing his direction with difficulty. The positions occupied by the Austrians were everywhere attacked at once; their troops, already demoralized by several defeats, retired in disorder. Kray fell back on Ulm, where an entrenched camp was ready for him. General Moreau was compelled to weaken his army by detaching a corps of 1800 men, necessary for the operations of the First Consul. He attempted without success a movement intended to turn the flank of General Kray, and resolved to blockade him in his positions, and wait for the result of the manoeuvres of Bonaparte. On the 27th May he wrote to Bonaparte, "We await with impatience the announcement of your success. M. de Kray and I are groping about here—he to keep his army round Ulm, I to make him quit the post. It would have been dangerous, especially for you, if I had carried the war to the left bank of the Danube. Our present position has forced the Prince of Reuss to remove himself to the passes of the Tyrol, to the sources of the Lech and the Iller; thus he is no longer dangerous for you. If M. de Kray comes towards me, I shall still retreat as far as Meiningen; there I shall join General Lecourbe, and we shall fight. If M. de Kray marches upon Augsburg, I shall do the same; he will quit his support at Ulm, and then we shall see what will have to be done to cover your movements. We should find more advantages in carrying on the war upon the left bank of the Danube, and making Wurtemberg and Franconia contribute to it; but that would not suit you, as the enemy would be able to send detachments down into Italy whilst leaving us to ravage the provinces of the Empire.
"Give me, I pray you, some news of yourself, and command me in every possible service I can render you."
All was thus prepared in Germany and Italy for the success of that campaign of the First Consul of which the enemy were still ignorant. Always deceived by the fictitious concentrations carried on at Dijon, the Austrians saw without disquietude the departure of Bonaparte, who left Paris, as it was said, for a few days, in order to pass in review the army of reserve. The French public shared the same illusion; the preparations eagerly pushed forward by the First Consul, remained secret. He set out at the last moment, leaving with regret, and not without uneasiness, his government scarcely established, and new institutions not yet in working order. "Keep firmly together," said he to Cambacérès and Lebrun; "if an emergency occurs, don't be alarmed at it. I will return like a thunderbolt, to crush those who are audacious enough to raise a hand against the government." He had in advance, by the powerful conceptions of his genius arranged the whole plan of operations, and divined the movements of his enemies. Bending over his maps, and designating with his finger the positions of the different corps, he muttered in a low voice, "This poor M. de Mélas will pass by Turin, he will fall back upon Alessandria. I shall pass the Po, and come up with him again on the road of Placenza, in the plains of the Scrivia; and I shall beat him there, and then there." The Tribunate expressed their desire that the First Consul might return soon, "conqueror and pacificator." An article of the Constitution forbade him to take the command of the armies; Berthier received the title of general-in-chief. The First Consul passed in review the army of conscripts and invalids assembled at Dijon. On May 13, he combined the active forces at Geneva; the troops coming from Germany under the command of General Moncey had not yet arrived; they were to pass by the St. Gothard. General Marescot had been ordered to reconnoitre the Alps; the pass of the St. Bernard, more difficult than that of the Simplon or Mont Cenis, was much shorter, and the passage from it could be much more easily defended. "Difficult it may be," replied the First Consul to the report of Marescot, "but is it possible?" "I think so," said the general, "with extraordinary efforts." "Ah, well! let us set out," said Bonaparte.
From Geneva to Villeneuve the journey was easy, and vessels carried provisions to that point. The First Consul had carefully arranged places for revictualling all along the road. At Montigny half the mules, requisitioned at great cost in the neighborhood, were loaded with victuals and munitions of war; the other half were attached to the gun carriages relieved of the cannon, which were to be again put in working order at San Remi, on the other side of the pass. The cannon themselves were enveloped in the hollowed trunks of trees; they could then be dragged over the ice and snow. The number of mules proving insufficient, and the peasants refusing to undertake this rough work, the soldiers yoked themselves to the cannon, and dragged them across the mountain without wishing to accept the rewards promised by the First Consul. He rode on a mule at the head of the rear-guard, wrapped in a gray greatcoat, chatting familiarly with his guide, and sustaining the courage of his soldiers by his unalterable coolness. After a few hours' rest at the hospice of St. Bernard commenced the descent, more difficult still than the ascent. From the 15th to the 20th of May the divisions followed each other. Lannes and Berthier, who commanded the vanguard, had already advanced to Aosta, when they found themselves stopped by the little fort of Bard, built upon a precipitous rock, and with artillery commanding the defile. It was now night; a layer of straw and refuse was spread over the frozen foot-path; the wheels of the gun-carriages were encased in tow; at the break of day the passage had been safely cleared. The French army, descending like a torrent into the valley, seized upon Ivry, and repulsed the Austrians at the Chiusella on May 26th. All the divisions of Bonaparte's army assembled by degrees; the corps of Moncey debouched by the St. Gothard, 4000 men under the orders of General Thureau crossed by Mont Cenis. General Mélas still refused to believe in the danger which menaced him, and already an imposing army was advancing against his scattered and divided forces. Already Lannes had beaten General Ott at Montebello, after a hotly disputed engagement. "I heard the bones crackle like a hailstorm on the roofs," said the conqueror.
Bonaparte threw himself upon Milan, neglecting Genoa, which he might have delivered without risk; thereby condemning Masséna and his army to the sufferings of a prolonged siege, terminated by a sad defeat. He had conceived vaster projects, and the design of annihilating the Austrian army by a single blow. Everything had to give way to the consideration of personal success and his egotistical thirst for glory. The Lombard populace received the First Consul with transport, happy to see themselves delivered from the Austrian yoke, and beguiled in advance with the hope of liberty. General Mélas was at Alessandria, summoning to his aid the forces that were attacking Suchet on the Var, and the troops of General Ott, detained by the siege of Genoa. He was assured of the impossibility of any succor being sent by Marshal Kray. It was necessary to conquer or die. In the prison in which the Austrian army detained him, Masséna had divined the situation of the enemy. He was still hoping for the assistance that had been promised him; already General Ott had sent him a flag of truce. "Give me only provisions for two days, or one day," said he to the Genoese, "and I will save you from the Austrian yoke, and spare my army the sorrow of surrender."
All resources were exhausted; the horrors of famine had worn out the courage of the inhabitants; even the soldiers were yielding to discouragement. "Before he will surrender," said they, "the general will make us eat his boots." For a long time the garrison had lived on unwholesome bread made with starch, upon linseed and cocoa, which scarcely sufficed to keep the soldiers alive; the population, reduced to live on soup made of herbs gathered on the ramparts, died by hundreds; the prisoners cantoned in the port in old dismasted vessels, uttered cries that reached the ears of their old generals. The latter had refused to send in provisions for the prisoners, in spite of the promise of Masséna to reserve it for them. The last food was used up; on the 3rd of June the general consented to receive the flag of truce. He asked for, and obtained, the honors of war; the army was authorized to depart from Genoa with arms and baggage, flags displayed, and free to direct its course towards the corps of General Suchet. "Without that I should issue arms in hand, and it should be seen what eight thousand famished men could do." War and famine had reduced to this number the soldiers in condition to carry arms. After their cure, the sick, who filled the hospitals, were to be sent to the quarters of General Suchet. Masséna defended the interests of the Genoese, and asked in their favor for a free government. The Austrian generals refused to make any engagement. "In less than a fortnight I shall be back again in Genoa," declared the French general. "You will find there the men whom you have taught how to defend it," replied St. Julien, one of the plenipotentiaries. General Soult remained in the place, seriously wounded. Masséna brought his exhausted troops to the Var. In the depths of their souls, generals and soldiers cherished a bitter resentment for the manner in which they had been abandoned. When the Austrian troops, beaten by Suchet, had retired towards Alessandria, Masséna did not allow him to pursue them; he contented himself with guarding the gates of France.
Bonaparte had just quitted Stradella, which he had occupied after leaving Milan. He had been obliged to disperse his forces, in order to cut off all the passages open to the enemy. When he entered, on June 13th, the plain that extends between the Scrivia and the Bormida, near the little village of Marengo, he was badly instructed as regards the movements of the enemy, as well as the resources of the country. On the morning of the 14th, General Mélas, constrained by necessity, evacuated Alessandria, and, passing the Bormida upon three bridges, attacked General Victor before Marengo. Lannes was at the same time surrounded on every side, and obliged to retreat in spite of prodigies of courage. Marengo had been destroyed by the artillery of the enemy, when Bonaparte arrived upon the field of battle with his guard and his staff officers, at once drawing upon himself the brunt of the fight. Meanwhile the retreat continued; the army seemed about to be cut in two; the Austrian general, old and fatigued, believing himself assured of victory, re-entered Alessandria. It was now three o'clock, and Bonaparte still hoped and kept on fighting. He despatched an aide-de-camp to Desaix, returned from Egypt two days before, and whom he had detached in the direction of Novi; upon his return depended the fortune of the day. Desaix had divined this, and forestalled the message of Bonaparte; before he could be expected he was beside the general, who questioned him as to the aspect of affairs. "Well," said Desaix, after having rapidly examined the situation of the different corps, "it is a lost battle; but it is not late; we have time to gain another." His regiments were forming whilst he spoke, stopping the march of the Austrians. "My friends," said the First Consul to the reanimated soldiers, "remember that it is my custom to sleep upon the field of battle."
At the same moment Desaix advanced at the heads of his troops. "Go and tell the First Consul that I am about to charge," said he to his aide-de- camp, Savary; "I need to be supported by cavalry." He was crossing an undulation in the ground when a ball struck him in the breast; from daybreak he had been oppressed by gloomy presentiments. "I have been too long making war in Africa," said he; "the bullets of Europe know me no longer." On falling he said to General Boudet, "Conceal my death; it might unsettle the troops." The soldiers had perceived it and rushed forward to avenge him. Kellermann arrived at the same instant, urged forward by one of those sudden inspirations which mark great generals; hurling his dragoons upon the Austrian cavalry, which he broke through, he attacked the column of grenadiers which arduously sustained the assault of the division of Desaix. Their ranks fell into disorder; one entire corps threw down its arms. General Zach, entrusted with the command in the absence of Mélas, was forced to give up his sword. When the old general hurried up in agitation, the battle was lost. The Austrian troops, repulsed and routed, and crowded against the banks of the Bormida, blocked up all the bridges, or cast themselves into the river, everywhere pursued by the victorious French. The cannon, which stuck fast in the Bormida, fell into the hands of the conquerors. The staff was decimated.
The First Consul regretted the loss of Desaix, the only one among the companions of his youth who had seemed able to inspire in him any particular regard. He was, however, triumphant, and this great day made him in fact the master of Italy. He had the wisdom to perceive it. The needs of government recalled him to France; the conditions he proposed to Mélas, although hard, were such as could be accepted. The Austrian army was authorized to retire with the honors of war; but it was to surrender to the French troops all its positions in Liguria, Piedmont, Lombardy, and the Legations, whilst evacuating the Italian territory as far as the Mincio. To the protests of Mélas, Bonaparte replied by a formal refusal to listen. "Sir," said he, "my conditions are irrevocable. I did not begin to made war yesterday. Your position is as well known to me as to yourself. You are in Alessandria, encumbered with the dead, the wounded, and the sick, and destitute of provisions; you have lost the élite of your army; you are surrounded on all sides. I could exact everything, but I only demand of you that which the situation of affairs imperatively requires. Return to Alessandria; you will have no other conditions."
Mélas signed, pledging his word until he should receive a reply from Vienna. On the same evening, before quitting the field of battle, the First Consul wrote for the second time to the Emperor Francis Joseph. He was moved to the very depths of his impassable and haughty soul by the spectacle of the carnage and fury of the battle. In subsequent calmer moments he perhaps regretted his letter. "It is upon the battlefield of Marengo," said he, "in the midst of agonies, and surrounded by 15,000 corpses, that I conjure your Majesty to listen to the cry of humanity, and not permit the children of two brave and powerful nations to massacre each other for interests which are foreign to them. It is for me to press this upon your Majesty, since I am the nearest to the theatre of war. Your heart cannot be so keenly alive to it as mine. The arms of your Majesty have achieved sufficient glory. You govern a large number of States. What then can those in the cabinet of your Majesty allege in favor of the continuation of hostilities? Is it the interests of religion and of the Church? Why do they not counsel your Majesty to make war on the English, the Muscovites, and the Prussians? They are further from the Church than we. Is it the form of the French Government, which is not hereditary but simply elective? But the government of the Empire is also elective; and besides, your Majesty is thoroughly convinced of the powerlessness of the entire world to change the desire which the French people have received from nature to govern themselves as they please. Is it the destruction of revolutionary principles? If your Majesty will take account of the effects of war you will see that it tends to revolutionize Europe, by increasing everywhere the public debt and the discontent of the people. In compelling the French people to make war, you compel them only to think of war, only to live in war; and the French legions are numerous and brave. If your Majesty wishes for peace it is done; let us give repose and tranquillity to the present generation. If future generations are foolish enough to fight—well, they will learn after a few years of war to become wise and live in peace. I might take captive the entire army of your Majesty. I am satisfied by a suspension of hostilities, having hopes that it may be the first step towards the repose of the world; an object for which I can plead all the more forcibly because, nurtured and schooled by war, I might be suspected of being more accustomed to the evils it drags after it. If your Majesty refuses these proposals, the hostilities will recommence; and let me be permitted to tell you frankly, in the eyes of the world you alone will be responsible for the war."
