In view of the facts that the allies were flushed with their recent victories, were superior to their adversary in numbers, and also held the mastery of the sea, they expected great results in the coming campaign. With so many advantages on their side, their plans seemed both reasonable and accomplishable; but they reckoned without the genius of Bonaparte. On the other side, Bonaparte had two plans, both of which it will be well to examine, that the reader may grasp the breadth of Bonaparte's intellect in originating strategic conceptions. Both plans were based upon the fact that the great stronghold of Switzerland, extending like a huge wedge between the Austrian army in Germany and that in Italy, was occupied by the French. This natural fortress, almost impregnable, could be used as a base of operations from which to attack either Kray in Germany or Melas in Italy. The first plan conceived by Bonaparte was to leave Masséna in Italy on the defensive to hold Melas in check, then to unite the Army of Reserve with Moreau's army, cross the Rhine in force between Schaffhausen and Lake Constance, and attack that part of Kray's army occupying the Black Forest in the angle of the Rhine between Lake Constance and Strasburg. By an attack in this direction, Bonaparte calculated that he could defeat Kray, drive him north, sever his communications with Vienna, and either destroy or capture his army. If successful in this operation, he could descend the Danube and seize the Emperor's capital; then by taking possession of the Tyrol and the Carnic Alps, he could occupy the Brenner and Pontebba passes, which operation would sever the communications of Melas in Italy and cut him off from Vienna. With Kray's army captured or destroyed, with the French holding the only passes by which the Austrians in Italy could retreat, and with Bonaparte in possession of the Austrian capital, the campaign must end; the Austrian Emperor would be compelled to make peace. This plan had many advantages. It would, if successful, be far-reaching in its results; it would not only destroy Kray, but would paralyze the operations of Melas; it would, to use Bonaparte's expressive words, "reconquer Italy at Vienna."
