What had happened to the Crown Prince of Wartemberg at Montereau, and to Count Wittgenstein at Mormant, Prince Schwartzenberg must have known well enough; but all the untoward events on Bluecher's distant and separate line from the Marne to the Rhine would only reach him by the avalanche of rumour.

The desperate movements which Buonaparte made upon Vitry at the end of March, to see what the Allies would do if he threatened to turn them strategically, were evidently done on the principle of working on their fears; but it was done under far different circumstances, in consequence of his defeat at Laon and Arcis, and because Bluecher, with 100,000 men, was then in communication with Schwartzenberg.
There are people, no doubt, who will not be convinced on these arguments, but at all events they cannot retort by saying, that "whilst Buonaparte threatened Schwartzenberg's base by advancing to the Rhine, Schwartzenberg at the same time threatened Buonaparte's communications with Paris," because we have shown by the reasons above given that Schwartzenberg would never have thought of marching on Paris.
With respect to the example quoted by us from the campaign of 1796, we should say: Buonaparte looked upon the plan he adopted as the surest means of beating the Austrians; but admitting that it was so, still the object to be attained was only an empty victory, which could have hardly any sensible influence on the fall of Mantua.

The way which we should have chosen would, in our opinion, have been much more certain to prevent the relief of Mantua; but even if we place ourselves in the position of the French General and assume that it was not so, and look upon the certainty of success to have been less, the question then amounts to a choice between a more certain but less useful, and therefore less important, victory on the one hand, and a somewhat less probable but far more decisive and important victory, on the other hand.

Presented in this form, boldness must have declared for the second solution, which is the reverse of what took place, when the thing was only superficially viewed.

Buonaparte certainly was anything but deficient in boldness, and we may be sure that he did not see the whole case and its consequences as fully and clearly as we can at the present time.
Naturally the critic, in treating of the means, must often appeal to military history, as experience is of more value in the Art of War than all philosophical truth.
