If, determined upon the imperious and unjust aggression on Bavaria, Mack found it necessary to advance more to the westward than the line of the Inn, in order to secure the country of the elector, the Lech, in its turn, offered him a position in which he might have awaited the Russians, though their junction must necessarily have been protracted, in proportion to the extent of his advance. But it was the choice of this unlucky tactician to leave Bavaria also behind him, and, approaching the frontiers of France, to take possession of Ulm, Memmingen, and the line of the Iller and Danube, where he fortified himself with great care, as if to watch the defiles of the Black Forest. It can only be thought by those who judge most favourably of Mack's intentions, that, as the passes of that celebrated forest had been frequently the route by which the French invaded Germany, he had concluded it must therefore be by that road, and no other, that their approach on the present occasion was to be expected. Knowing with whom he had to contend, the Austrian general ought to have suspected the direct contrary; for Buonaparte's manœuvres were not more distinguished by talent, than by novelty and originality of design.[124]
It is not to be supposed that this great confederacy took at unawares one who had so many reasons for being alert. The Austrian forces, though they had commenced the campaign so hastily, were not more early ready for the field, than were the immense armies of the French empire. The camps at Boulogne, so long assembled on the shores of the Channel, were now to be relieved from their inactivity;[125] and serious as the danger was in which their assistance was required, Buonaparte was perhaps not displeased at finding a fair pretext to withdraw from the invasion to which he had hastily pledged himself. This formidable assemblage of troops, laying aside the appellation of the Army of England, was hereafter distinguished by that of the Grand Army. At the same time, the armies maintained in Holland, and in the North of Germany, were put into motion.
In this remarkable campaign Buonaparte commenced, for the first time, the system of issuing official bulletins, for the purpose of announcing to the French nation his accounts of success, and impressing upon the public mind what truths he desired them to know, and, at the same time, what falsehoods he was desirous they should believe. In every country, such official accounts will naturally have a partial character, as every government must desire to represent the result of its measures in as favourable a light as possible. Where there is a free press, however, the deception cannot be carried to extremity; imposture cannot be attempted, on a grand scale at least, where it can be contrasted with other sources of information, or refuted by arguments derived from evidence. But Buonaparte had the unlimited and exclusive privilege of saying what he pleased, without contradiction or commentary, and he was liberal in using a license which could not be checked. Yet his bulletins are valuable historical documents, as well as the papers in the Moniteur, which he himself frequently composed or superintended. Much correct information there certainly is; and that which is less accurate is interesting, since it shows, if not actual truths, at least what Napoleon desired should be received as such, and so throws considerable light both on his schemes and on his character.
Buonaparte communicated to the Senate the approach of war, by a report, dated 23d September,[126] in which, acquainting them with the cause of quarrel betwixt himself and the allied powers, he asked, and of course obtained, two decrees; one for ordering eighty thousand conscripts to the field, another for the organisation of the National Guard.[127] He then put himself at the head of his forces, and proceeded to achieve the destruction of Mack's army, not as at Marengo by one great general battle, but by a series of grand manœuvres, and a train of partial actions necessary to execute them, which rendered assistance and retreat alike impossible. These manœuvres we can only indicate; nor can they perhaps be well understood without the assistance of the map.
MANŒUVRES OF FRENCH GENERALS.
While Mack expected the approach of the French upon his front, Buonaparte had formed the daring resolution to turn the flank of the Austrian general, cut him off from his country and his resources, and reduce him to the necessity, either of surrender, or of giving battle without a hope of success. To execute this great conception, the French army was parted into six grand divisions. That of Bernadotte, evacuating Hanover, which it had hitherto occupied, and traversing Hesse, seemed as if about to unite itself to the main army, which had now reached the Rhine on all points. But its real destination was soon determined, when, turning towards the left, Bernadotte ascended the river Maine, and at Wurtzburg formed a junction with the elector of Bavaria, who, with the troops which had followed him into Franconia, immediately declared for the French cause.
The elector of Wirtemberg and the Duke of Baden followed the same line of politics; and thus Austria had arrayed against her those very German princes, whom a moderate conduct towards Bavaria might perhaps have rendered neutral; France, at the outset of the contest, scarce having the power to compel them to join her standard. The other five columns of French troops, under Ney, Soult, Davoust, Lannes, and Marmont, crossed the Rhine at different points, and entered Germany to the northward of Mack's position; while Murat, who made his passage at Kehl, approaching the Black Forest, manœuvred in such a manner as to confirm Mack in his belief that the main attack was to come from that quarter. But the direction of all the other divisions intimated that it was the object of the French Emperor to move round the right wing of the Austrians, by keeping on the north or left side of the Danube, and then by crossing that river, to put themselves in the rear of Mack's army, and interpose betwixt him and Vienna. For this purpose, Soult, who had crossed at Spires, directed his march upon Augsburg; while, to interrupt the communication betwixt that city and Ulm, the Austrian headquarters, Murat and Lannes had advanced to Wertingen, where a smart action took place. The Austrians lost all their cannon, and it was said four thousand men—an ominous commencement of the campaign. The action would have been termed a battle, had the armies been on a smaller scale; but where such great numbers were engaged on either side, it did not rank much above a skirmish.[128]
With the same purpose of disquieting Mack in his headquarters, and preventing him from attending to what passed on his left wing and rear, Ney, who advanced from Stutgard, attacked the bridges over the Danube at Guntzburg, which were gallantly but fruitlessly defended by the Archduke Ferdinand, who had advanced from Ulm to that place. The archduke lost many guns, and nearly three thousand men.[129]
