But these reflections belong properly to tactics, and are only introduced here by way of example for the sake of greater clearness. What strategy has to say on the different objects of the combat will appear in the chapters which touch upon these objects. Here we have only a few general observations to make, first, that the importance of the object decreases nearly in the order as they stand above, therefore, that the first of these objects must always predominate in the great battle; lastly, that the two last in a defensive battle are in reality such as yield no fruit, they are, that is to say, purely negative, and can, therefore, only be serviceable, indirectly, by facilitating something else which is positive. It is, therefore, a bad sign of the strategic situation if battles of this kind become too frequent.
