Jourdan themselves, surmounted difficulties instead of lamenting them.
On the other side, Carnot, of course, foresaw this possibility. He warned the generals not to allow the enemy to “use his forces sometimes against one, sometimes against the other, as he did in the last campaign,” and ordered them to go forward respectively into Franconia and into the country of the upper Neckar, with a view to seeking out and defeating the enemy’s army. But the plan of operations soon grew bolder. Jourdan was informed on the 21st of July that if he reached the Regnitz without meeting the enemy, or if his arrival there forced the latter to retire rapidly to the Danube, he was not to hesitate to advance to Ratisbon and even to Passau if the disorganization of the enemy admitted it, but in these contingencies he was to detach a force into Bohemia to levy contributions. “We presume that the enemy is too weak to offer a successful resistance and will have united his forces on the Danube; we hope that our two armies will act in unison to rout him completely. Each is, in any case, strong enough to attack by itself, and nothing is so pernicious as slowness in war.” Evidently the fear that the two Austrian armies would unite against one of their assailants had now given place to something like disdain.
This was due in all probability to the rapidity with which Moreau was driving the archduke before him. After a brief stand on the Neckar at Cannstadt, the Austrians, only 25,000 strong, fell back to the Rauhe Alb, where they halted again, to cover their magazines at Ulm and Günzburg, towards the end of July. Wartensleben was similarly falling back before Jourdan, though the latter, starting considerably later than Moreau, had not advanced so far. The details of the successive positions occupied by Wartensleben need not be stated; all that concerns the general development of the campaign is the fact that the hitherto independent leader of the “Lower Rhine Army” resented the loss of his freedom of action, and besides lamentations opposed a dull passive resistance to all but the most formal orders of the prince. Many weeks passed before this was overcome sufficiently for his leader even to arrange for the contemplated combination, and in these weeks the archduke was being driven back day by day, and the German principalities were falling away one by one as the French advanced and preached the revolutionary formula. In such circumstances as these—the general facts, if not the causes, were patent enough—it was natural that the confident Paris strategists should think chiefly of the profits of their enterprise and ignore the fears of the generals at the front. But the latter were justified in one important respect; their operating armies had seriously diminished in numbers, Jourdan disposing of not more than 45,000 and Moreau of about 50,000. The archduke had now, owing to the arrival of a few detachments from the Black Forest and elsewhere, about 34,000 men, Wartensleben almost exactly the same, and the former, for some reason which has never been fully explained but has its justification in psychological factors, suddenly turnedNeresheim. and fought a long, severe and straggling battle above Neresheim (August 11). This did not, however, give him much respite, and on the 12th and 13th he retired over the Danube. At this date Wartensleben was about Amberg, almost as far away from the other army as he had been on the Rhine, owing to the necessity of retreating round instead of through the principality of Bayreuth, which was a Prussian possession and could therefore make its neutrality respected.
Hitherto Charles had intended to unite his armies on the Danube against Moreau. His later choice of Jourdan’s army as the objective of his combination grew out of circumstances and in particular out of the brilliant reconnaissance work of a cavalry brigadier of the Lower Rhine Army, Nauendorff. This general’s reports—he was working in the country south and south-east of Nürnberg, Wartensleben being at Amberg—indicated first an advance of Jourdan’s army from Forchheim through Nürnberg to the south, and induced the archduke, on the 12th, to begin a concentration of his own army towards Ingolstadt. This was a purely defensive measure, but Nauendorff reported on the 13th and 14th that the main columns of the French were swinging away to the east against Wartensleben’s front and inner flank, and on the 14th he boldly suggested the idea that decided the campaign. “If your Royal Highness will or can advance 12,000 men against Jourdan’s rear, he is lost. We could not have a better opportunity.” When this message arrived at headquarters the archduke had already issued orders to the same effect. Lieutenant Field Marshal Count Latour, with 30,000 men, was to keep Moreau occupied—another expedient of the moment, due to the very close pressure of Moreau’s advance, and the failure of the attempt to put him out of action at Neresheim. The small remainder of the army, with a few detachments gathered en route, in all about 27,000 men, began to recross the Danube on the 14th, and slowly advanced north on a broad front, its leader being now sure that at some point on his line he would encounter the French, whether they were heading for Ratisbon or Amberg. Meanwhile, the Directory had, still acting on the theory of the archduke’s weakness, ordered Moreau to combine the operations with those of Bonaparte in Italian Tirol, and Jourdan to turn both flanks of his immediate opponent, and thus to prevent his joining the archduke, as well as his retreat into Bohemia. And curiously enough it was this latter, and not Moreau’s move, which suggested to the archduke that his chance had come. The chance was, in fact, one dear to the 18th century general, catching his opponent in the act of executing a manœuvre. So far from “exterior lines” being fatal to Jourdan, it was not until the French general began to operate against Wartensleben’s inner flank that the archduke’s opportunity came.
The decisive events of the campaign can be described very briefly, the ideas that directed them having been made clear. The long thin line of the archduke wrapped itself round Jourdan’s right flank near Amberg, while Wartensleben fought him in front. The battle (August 24) was a Amberg and Würzburg.series of engagements between the various columns that met; it was a repetition in fact of Fleurus, without the intensity of fighting spirit that redeems that battle from dulness. Success followed, not upon bravery or even tactics, but upon the pre-existing strategical conditions. At the end of the day the French retired, and next morning the archduke began another wide extension to his left, hoping to head them off. This consumed several days. In the course of it Jourdan attempted to take advantage of his opponent’s dissemination to regain the direct road to Würzburg, but the attempt was defeated by an almost fortuitous combination of forces at the threatened point. More effective, indeed, than this indirect pursuit was the very active hostility of the peasantry, who had suffered in Jourdan’s advance and retaliated so effectually during his retreat that the army became thoroughly demoralized, both by want of food and by the strain of incessant sniping. Defeated again at Würzburg on the 3rd of September, Jourdan continued his retreat to the Lahn, and finally withdrew the shattered army over the Rhine, partly by Düsseldorf, partly by Neuwied. In the last engagement on the Lahn the young and brilliant Marceau was mortally wounded. Far away in Bavaria, Moreau had meantime been driving Latour from one line of resistance to another. On receiving the news of Jourdan’s reverses, however, he made a rapid and successful retreat to Strassburg, evading the prince’s army, which had ascended the Rhine valley to head him off, in the nick of time.
This celebrated campaign is pre-eminently strategical in its character, in that the positions and movements anterior to the battle preordained its issue. It raised the reputation of the archduke Charles to the highest point, and deservedly, for he wrested victory from the most desperate circumstances by the skilful and resolute employment of his one advantage. But this was only possible because Moreau and Jourdan were content to accept strategical failure without seeking to redress the balance by hard fighting. The great question of this campaign is, why did Moreau and Jourdan fail against inferior numbers, when in Italy Bonaparte with a similar army against a similar opponent won victory after victory against equal and superior forces? The answer will not be supplied by any theory of “exterior and
