The consequences of thus weakening the Austrian force on the Rhine were, for the moment, on that scene of the contest, inauspicious. The French, in two separate bodies, forced the passage of the Rhine--under Jourdan and Moreau; before whom the imperial generals, Wartensleben and the Archduke Charles, were compelled to retire. But the skill of the Archduke ere long enabled him to effect a junction with the columns of Wartensleben; and thus to fall upon Jourdan with a great superiority of numbers, and give him a signal defeat. The loss of the French in the field was great, and the bitter hostility of the German peasantry made their retreat a bloody one. Moreau, on the other hand, learning how Jourdan was discomfited, found himself compelled to give up the plan of pursuing his march further into Germany, and executed that famous retreat through the Black Forest which has made his name as splendid as any victory in the field could have done. But this reverse, however alleviated by the honours of Moreau's achievement, was attended with appearances of the most perilous kind. The genius of Carnot had devised a great scheme of operations, of which one half was thus at once cut short. He had meant Moreau and Jourdan, coalescing beyond the Rhine, to march upon the Tyrol; while Buonaparte should advance from the scene of his Italian conquests, join his brother generals on that frontier, and then march in union with them to dictate a peace before the gates of Vienna. All hope of this junction of forces was now at an end for this campaign. The French saw themselves compelled to resume the defensive on the western frontier of Germany; and the army of Italy had to await the overwhelming war which seemed ready to pour down upon Lombardy from the passes of the Tyrol. Wurmser, when he fixed his headquarters at Trent, mustered in all 80,000; while Buonaparte had but 30,000, to hold a wide country, in which abhorrence of the French cause was now prevalent, to keep up the blockade of Mantua, and to oppose this fearful odds of numbers in the field. He was now, moreover, to act on the defensive, while his adversary assumed the more inspiriting character of invader. He awaited the result with calmness.
