But even this decision of the total combat has only a relative meaning of many different gradations, according as the force over which the victory has been gained forms a more or less great and important part of the whole. The lost battle of a corps may be repaired by the victory of the Army. Even the lost battle of an Army may not only be counterbalanced by the gain of a more important one, but converted into a fortunate event (the two days of Kulm, August 29 and 30, 1813(*)). No one can doubt this; but it is just as clear that the weight of each victory (the successful issue of each total combat) is so much the more substantial the more important the part conquered, and that therefore the possibility of repairing the loss by subsequent events diminishes in the same proportion. In another place we shall have to examine this more in detail; it suffices for the present to have drawn attention to the indubitable existence of this progression. (*) Refers to the destruction of Vandamme’s column, which had been sent unsupported to intercept the retreat of the Austrians and Prussians from Dresden—but was forgotten by Napoleon.—EDITOR. If we now add lastly to these two considerations the third, which is, that if the persistent use of forces in tactics always shifts the great result to the end of the whole act, law of the simultaneous use of the forces in Strategy, on the contrary, lets the principal result (which need not be the final one) take place almost always at the commencement of the great (or whole) act, then in these three results we have grounds sufficient to find strategic reserves always more superfluous, always more useless, always more dangerous, the more general their destination. The point where the idea of a strategic reserve begins to become inconsistent is not difficult to determine: it lies in the SUPREME DECISION. Employment must be given to all the forces within the space of the supreme decision, and every reserve (active force available) which is only intended for use after that decision is opposed to common sense. If, therefore, tactics has in its reserves the means of not only meeting unforeseen dispositions on the part of the enemy, but also of repairing that which never can be foreseen, the result of the combat, should that be unfortunate; Strategy on the other hand must, at least as far as relates to the capital result, renounce the use of these means. As A rule, it can only repair the losses sustained at one point by advantages gained at another, in a few cases by moving troops from one point to another; the idea of preparing for such reverses by placing forces in reserve beforehand, can never be entertained in Strategy.
