There is therefore a very natural tendency to use this moral force to repair the disaster on the spot, and on that account chiefly to seek another battle if other circumstances permit. It then lies in the nature of the case that this second battle must be an offensive one.
In the catalogue of battles of second-rate importance there are many examples to be found of such retaliatory battles; but great battles have generally too many other determining causes to be brought on by this weaker motive.
Such a feeling must undoubtedly have led the noble Blücher with his third Corps to the field of battle on February 14, 1814, when the other two had been beaten three days before at Montmirail. Had he known that he would have come upon Buonaparte in person, then, naturally, preponderating reasons would have determined him to put off his revenge to another day: but he hoped to revenge himself on Marmont, and instead of gaining the reward of his desire for honourable satisfaction, he suffered the penalty of his erroneous calculation.
On the duration of the combat and the moment of its decision depend the distances from each other at which those masses should be placed which are intended to fight in conjunction with each other. This disposition would be a tactical arrangement in so far as it relates to one and the same battle; it can, however, only be regarded as such, provided the position of the troops is so compact that two separate combats cannot be imagined, and consequently that the space which the whole occupies can be regarded strategically as a mere point. But in War, cases frequently occur where even those forces intended to fight in unison must be so far separated from each other that while their union for one common combat certainly remains the principal object, still the occurrence of separate combats remains possible. Such a disposition is therefore strategic.
