Jean Baptiste Bernadotte, the son of a petty lawyer, was born at Pau on January 26, 1763. At the age of seventeen he enlisted in the Royal Marine regiment and passed the next nine years of his life in garrison towns in Corsica, Dauphiné and Provence. His first notable exploit occurred in 1788, when, as sergeant, he commanded a section of the Marines whose duty it was to maintain order at Grenoble during the troubles which preceded the outbreak of the Revolution. The story goes that Bernadotte was responsible for the first shedding of blood. One day, when the mob was threatening to get out of hand, a woman rushed out of the crowd and caught the sergeant a cuff on the face, whereon the fiery Gascon ordered his men to open fire. In a moment the answer came in a shower of bricks. Blood had been shed, and from that moment the people of France declared war to the death on the old régime. Impetuous, generous, warm-hearted and ambitious, for the next three years Jean Baptiste pursued a policy which is typical of his whole career. Ready when at white heat of passion to take the most extreme measures, even to fire on the crowd, in calmer moments full of enthusiasm for the Rights of Man and the well-being of his fellows; spending long hours haranguing his comrades on the iniquity of kingship and the necessity of taking up arms against all of noble birth, yet standing firm by his colonel, because in former days he had done him a kindness, and saving his officers from the mutineers who were threatening to hang them; watching every opportunity to push his own fortunes, Bernadotte pursued his way towards success. Promotion came rapidly: colonel in 1792, the next year general of brigade, and a few months later general of division, he owed his advancement to the way in which he handled his men. Naturally great neither as tactician or as strategist, he could carry out the orders of others and above all impart his fiery nature to his troops; his success on the battlefield was due to his personal magnetism, whereby he inspired others with his own self-confidence. But with all this self-confidence there was blended in his character a curious strain of hesitation. Again and again during his career he let "I dare not" wait upon "I would." Gascon to the backbone, full of craft and wile, with an eye ever on the future, at times he allowed his restless imagination to conjure up dangers instead of forcing it to show him the means to gain his end. When offered the post of general of brigade, and again when appointed general of division, he refused the step because he had divined that Jacobin would persecute Girondist, that ultra-Jacobin would overthrow Jacobin, and that a reaction would sweep away the Revolutionists, and he feared that the generals of the army might share the fate of those who appointed them. After his magnificent attack at Fleurus, he was at last compelled to accept promotion by Kléber, who rode up to him and cried out, "You must accept the grade of general of brigade here on the field of battle, where you have so truly earned it. If you refuse you are no friend of mine." Thereon Bernadotte accepted the post, considering that he could, if necessary, prove that he had not received it as a political favour. The years 1794-6 saw Bernadotte on continuous active service with the Army of the Sambre and Meuse, now in the Rhine valley, now in the valley of the Danube. Every engagement from Fleurus to Altenkirchen added more and more to his reputation with the authorities and to his hold on the affection of his men. "He is the God of armies," cried his soldiers, as they followed him into the fire-swept zone. His courage, personality and physical beauty captivated all who approached him. Tall, erect, with masses of coal black hair, the great hooked nose of a falcon, and dark flashing eyes indicating Moorish blood in his veins, he could crush the soul out of an incipient revolt with a torrent of cutting words, and in a moment turn the mutineers into the most loyal and devoted of soldiers. During the long revolutionary wars he always kept before him the necessity of preparing for peace, and found time to educate himself in history and political science. It was with the reputation of being one of the best divisional officers of the Army of the Sambre and Meuse, and a political power of no small importance, that, at the end of 1796, Bernadotte was transferred with his division to the Army of Italy, commanded by Bonaparte. From their very first meeting friction arose. They were like Cæsar and Pompey, "the one would have no superior, the other would endure no equal." Bonaparte already foresaw the day when France should lie at his feet; he instinctively divined in Bernadotte a possible rival. Bernadotte, accustomed to the adulation of all with whom he came in contact, felt the loss of it in his new command, where soldiers and officers alike could think and speak of nobody save the conqueror of Italy. Yet neither could afford to break with the other, neither could as yet foretell what the future would bring forth, so amid an occasional flourish of compliments, a secret and vindictive war was waged between the two. As commander-in-chief, Bonaparte, for the time being, held the whip hand and could show his dislike by severe reprimands. "Wherever your division goes, there is nothing but complaints of its want of discipline." Bernadotte, on his side, anxious to win renown, would appeal to the "esprit" of his soldiers of the Sambre and Meuse, and would spoil Bonaparte's careful combinations by attempting a frontal attack before the turning movement was effected by the Italian divisions. By the end of the campaign it was clear to everybody that there was no love lost between the two. After Leoben Bonaparte was for the moment the supreme figure in France. As plenipotentiary at Leoben and commander-in-chief of "the Army of England" he could impose his will on the Directory. Bernadotte, in disgust at seeing the success of his rival, for some time seriously considered withdrawing from public life, or at any rate from France, where his reputation was thus overshadowed. Among various posts, the Directory offered him the command of the Army of Italy, but he refused them all, till at last he consented to accept that of ambassador at Vienna. Vienna was for the time being the pole round which the whole of European politics revolved, and accordingly there was great possibility there of achieving diplomatic renown. But scarcely had the new ambassador arrived at his destination when he heard of Bonaparte's projected expedition to Egypt. He at once determined to return to France. He felt that his return ought to be marked by something which might appeal to the populace. Accordingly he adopted a device at once simple and effective.

Jacobin at heart when his interest did not clash with his principles, he had from his arrival at Vienna determined to show the princes and dignitaries of an effete civilisation that Frenchmen were proud of their Revolution and believed in nothing but the equality of all men; he refused to conform to court regulations and turned his house into a club for the German revolutionists. His attitude was of course resented, and there was considerable feeling in Vienna against the French Embassy. It only required, therefore, a little more bravado and a display of the tricolour on the balcony of the Embassy to induce the mob to attack the house. Immediately this occurred Bernadotte lodged a complaint, threw up his appointment, and withdrew to France as a protest against this "scoundrelly" attack on the honour of his country and the doctrine of the equality of men.

On his arrival at Paris he found the Directory shaken to its foundation. Sièyes, the inveterate constitution-monger, who saw the necessity of "a man with a head and a sword," greeted him joyfully; the banishment of Pichegru, the death of Hoche, the disgrace of Moreau, and the absence of Bonaparte had left Bernadotte for the moment the most important of the political soldiers of the Revolution. Acting on Sièyes's advice, Bernadotte refused all posts offered him either in the army or in the Government and awaited developments. Meanwhile he became very intimate with Joseph Bonaparte, who introduced him to his sister-in-law, Désiré Clary. The Clarys were merchants of Marseilles, and Désiré had for some time been engaged to Napoleon Bonaparte, who had jilted her on meeting Josephine. Désiré, very bitter at this treatment, accepted Bernadotte, as she said in later life, "because I was told that he was a man who could hold his own against Napoleon." This marriage was a master-stroke of policy; it at once gave Bernadotte the support of the Bonaparte family, for Bonaparte in his way was still fond of Désiré, and at the same time it gave Bernadotte a partner who at bottom hated Napoleon with a rancour equal to his own. After the disasters in Italy and on the Danube, on July 2, 1799, Bernadotte, thinking the time was come, accepted the post of Minister of War. He speedily put in the field a new army of one hundred thousand men, and by his admirable measures for the instruction of conscripts and for the collection of war material he was in no small way responsible, not only for Masséna's victory of Zurich, but, as Napoleon himself confessed, for the triumph of Marengo.

His term of office, however, was short, for his colleagues intrigued against him. Sièyes desired a man who would overthrow the Directory and establish a dictatorship: Barras was coquetting with the Bourbons. Bernadotte himself talked loudly of the safety of the Republic, but had not the courage to jump with Sièyes or to crouch with Barras. Oppressed by doubt, his imagination paralysed his action, and his personality, which only blazed when in movement, became dull. Still trusting his reputation and thinking that he was indispensable to the Directory, he tendered his resignation, hoping thus to check the intrigues of Sièyes and Barras. To his surprise it was at once accepted, and he found himself a mere nonentity.

On September 14th Bernadotte resigned, on October 9th Napoleon landed at Fréjus. During the Revolution of the 18th Brumaire Bernadotte remained in the background. Desiring the safety of France by the reorganisation of the Directory, hating the idea of a dictatorship, jealous of the success of his rival, he refused to join the stream of generals which hurried to the feet of the conqueror of Italy and Egypt. Bonaparte, who could read his soul like a book, attempted to draw his rival into his net, but, as ever, the Gascon could not make up his mind. At first he was inclined to join in the conspiracy, but at last he refused, and told Bonaparte that, if the Directory commanded him, he would take up arms against those who plotted against the Republic. Still, even on the eventful day he hesitated, and appeared in the morning among the other conspirators at Bonaparte's house, but not in uniform, thinking thus to serve both parties.

During the years which succeeded the establishment of the Consulate, Bernadotte waged an unending subterranean war against Napoleon. Scarcely a year passed in which his name was not connected with some conspiracy to overthrow the First Consul. Of these Napoleon was well advised, but Bernadotte was too cunning to allow himself to be compromised absolutely. However much he might sympathise with the conspirators and lend them what aid he could, he always refused to sign his name to any document. Accordingly, although on one occasion a bundle of seditious proclamations was found in the boot of his aide-de-camp's carriage, the charge could not be brought home. On another occasion, when it was proved that he had advanced twelve thousand francs to the conspirator Cerrachi, he could prove that it was the price he had paid the artist for a bust. In spite of the fact that no definite proof could be brought against him, the First Consul could easily, if he chose, have produced fraudulent witnesses or have had him disposed of by a court-martial, as he got rid of the Duc d'Enghien. Napoleon waited his time. He was afraid of a Jacobin outbreak if he made a direct attack against him. Further, Bernadotte had a zealous friend and ally in Joseph Bonaparte. So when pressed to take stern measures against his enemy, Napoleon always refused to do so, partly from policy, partly because of his former love for Désiré, and partly from the horror of a scandal in his family, which might weaken his position when he seized the imperial throne. Accordingly he attempted in every way to conciliate his rebellious subject, and at the same time to place him in positions where he could do no political harm. Together with Brune and Marmont, he made him a Senator. He offered him the command of the Army of Italy, and, when Bernadotte refused and demanded employment at home, he posted him to the command of the division in Brittany, with headquarters at Rennes. But the First Consul found that Rennes, far off as it was, was too close to Paris; accordingly he tried to tempt his Jacobin general by important posts abroad. He proposed in succession the embassy at Constantinople, the captain-generalcy at Guadaloupe, and the governorship of Louisiana, but Bernadotte refused to leave France. At last, early in 1803 Napoleon nominated him minister to the United States. Three times the squadron of frigates got ready to accompany the new minister, but each time the minister postponed his departure. Meanwhile war broke out with England, and Bernadotte was retained in France as general on the unattached list, owing to the efforts of Joseph.

On the establishment of the Empire Napoleon included Bernadotte's name among the number of the Marshals, partly to please his brother Joseph and to maintain the prestige of his family and partly, as in the case of Augereau, Masséna and Jourdan, to win over the staunch republicans and Jacobins to the imperial régime. For the moment the Emperor achieved his object. The ex-Jacobin, proud of his new title and luxuriating in his lately acquired estate of Grosbois, was actually grateful; but still, Gascon-like, he wanted more and complained he had not enough to maintain his proper state. Napoleon, hearing of this from Fouché, exclaimed: "Take from the public treasury enough to put this right. I want Bernadotte to be content. He is just beginning to say he is full of attachment for my person; this may attach him more." But a few days later the Marshal revealed his true feelings when, talking of Napoleon to Lucien, he said, "There will be no more glory save in his presence and by his side and through his means, and unfortunately all for him."

Though the Emperor had promoted him to honour, it was no part of his scheme to allow to remain in Paris a man who, as Talleyrand said, "was capable of securing four cut-throats and making away with Napoleon himself if necessary, a furious beast, a grenadier capable of all and everything, a man to be kept at a distance at all cost." Accordingly the Marshal very soon found himself sent to replace Mortier in command of the "Army of Hanover."

For fifteen months Bernadotte administered Hanover, and the subtle courtesy he showed to friend and foe alike made him as usual the adored of all with whom he came in contact. But whatever he did, the Emperor still suspected him, and gave the cue to all, that Bernadotte was not to be trusted and was no soldier. Napoleon always took care that Bernadotte should never have under his command French soldiers. His troops in 1805 were Bavarians; in 1807, Poles; in 1808, a mixture of Dutch and Spaniards; and in 1809, of Poles and Saxons. Berthier, working out the Emperor's ideas, and himself also hating Bernadotte, took care that in the allotment of duties the disagreeable and unimportant tasks should fall to the Marshal. In spite of the inferiority of his troops, Bernadotte as usual distinguished himself in the hour of battle. At Austerlitz, at the critical moment, he saw that unless the centre was heavily supported Napoleon's plan of trapping the Russians must fail, so without waiting orders he detached a division towards the northern slopes of the plateau, and thus materially assisted in winning the day. But though quickwitted and alert on the battlefield, he never shone in strategy. In the movements which led up to a battle he was always slow and inclined to hesitate, and his detractors seized on this fault to declare, with Napoleon's connivance, that he was a traitor to the Emperor and to France. An incident of the campaign of 1806 gave the Marshal's enemies an excellent opening for showing their dislike. Napoleon, thinking he had cornered the whole Prussian army at Jena on the night of October 13th, sent orders to Bernadotte to fall back from Naumburg and get across the Prussian line of retreat. In pursuance of these orders the Marshal left Naumburg at dawn on the morning of the 14th and marched in the direction of Apolda, which he reached, in spite of the badness of the roads, by 4 p.m., and thereby captured about a thousand prisoners. But Napoleon had been mistaken in his calculations; the main Prussian force was not at Jena, but at Auerstädt, where it was most pluckily engaged and beaten by Davout, who at once sent to ask aid of Bernadotte; but the Marshal, according to Napoleon's definite orders, pursued his way to Apolda. The Emperor, to vent his dislike against Bernadotte and to cover up his own mistake, asserted that he had sent him orders to go to Davout's assistance, but a careful examination of the French despatches proves that no such document existed; in fact, the official despatches completely exonerate Bernadotte. Before the campaign was finished, Napoleon had to give the Marshal the praise he merited, when, aided by Soult and Murat, he at last forced Blücher to surrender with twenty-five thousand men and all the Prussian artillery at Lübeck. At Eylau Bernadotte's ill luck once again pursued him, for the staff officers sent to order him to march to the field of battle were taken by the enemy. This misfortune gave another opportunity to his detractors, and again the Emperor lent his authority to their false accusations. While secretly countenancing every attack on the Marshal, the Emperor, for family reasons, was loth to come to an open breach. On June 5, 1806, he had created him Prince of Ponte Corvo, a small principality in Italy wedged in between the kingdom of Naples and the Papal States; his reason for so doing he explained in a letter to his brother Joseph, the King of Naples. "When I gave the title of duke and prince to Bernadotte, it was in consideration of you, for I have in my armies many generals who have served me better and on whose attachment I can count more. But I thought it proper that the brother-in-law of the Queen of Naples should hold a distinguished position in your country." It was for this reason also that, after the treaty of Tilsit, the Emperor presented the Prince with vast domains in Poland and Hanover.
