Although the sum of all military events which happen in all the Theatres of War in one year is often called a Campaign, still, however, it is more usual and more exact to understand by the term the events in one single Theatre of War. But it is worse still to connect the notion of a Campaign with the period of one year, for wars no longer divide themselves naturally into Campaigns of a year’s duration by fixed and long periods in winter quarters. As, however, the events in a Theatre of War of themselves form certain great chapters—if, for instance, the direct effects of some more or less great catastrophe cease, and new combinations begin to develop themselves—therefore these natural subdivisions must be taken into consideration in order to allot to each year (Campaign) its complete share of events. No one would make the Campaign of 1812 terminate at Memel, where the armies were on the 1st January, and transfer the further retreat of the French until they recrossed the Elbe to the campaign of 1813, as that further retreat was plainly only a part of the whole retreat from Moscow.

That we cannot give these conceptions any greater degree of distinctness is of no consequence, because they cannot be used as philosophical definitions for the basis of any kind of propositions. They only serve to give a little more clearness and precision to the language we use.

CHAPTER III.
Relation of Power

In the eighth chapter of the third book we have spoken of the value of superior numbers in battles, from which follows as a consequence the superiority of numbers in general in strategy. So far the importance of the relations of power is established: we shall now add a few more detailed considerations on the subject.

An unbiassed examination of modern military history leads to the conviction that the superiority in numbers becomes every day more decisive; the principle of assembling the greatest possible numbers for a decisive battle may therefore be regarded as more important than ever.

Courage and the spirit of an army have, in all ages, multiplied its physical powers, and will continue to do so equally in future; but we find also that at certain periods in history a superiority in the organisation and equipment of an army has given a great moral preponderance; we find that at other periods a great superiority in mobility had a like effect; at one time we see a new system of tactics brought to light; at another we see the art of war developing itself in an effort to make a skilful use of ground on great general principles, and by such means here and there we find one general gaining great advantages over another; but even this tendency has disappeared, and wars now go on in a simpler and more natural manner.—If, divesting ourselves of any preconceived notions, we look at the experiences of recent wars, we must admit that there are but little traces of any of the above influences, either throughout any whole campaign, or in engagements of a decisive character—that is, the great battle, respecting which term we refer to the second chapter of the preceding book.

Armies are in our days so much on a par in regard to arms, equipment, and drill, that there is no very notable difference between the best and the worst in these things. A difference may still be observed, resulting from the superior instruction of the scientific corps, but in general it only amounts to this, that one is the inventor and introducer of improved appliances, which the other immediately imitates. Even the subordinate generals, leaders of corps and divisions, in all that comes within the scope of their sphere, have in general everywhere the same ideas and methods, so that, except the talent of the commander-in-chief—a thing entirely dependent on chance, and not bearing a constant relation to the standard of education amongst the people and the army—there is nothing now but habituation to war which can give one army a decided superiority over another. The nearer we approach to a state of equality in all these things, the more decisive becomes the relation in point of numbers.

The character of modern battles is the result of this state of equality. Take for instance the battle of Borodino, where the first army in the world, the French, measured its strength with the Russian, which, in many parts of its organisation, and in the education of its special branches, might be considered the furthest behindhand. In the whole battle there is not one single trace of superior art or intelligence, it is a mere trial of strength between the respective armies throughout; and as they were nearly equal in that respect, the result could not be otherwise than a gradual turn of the scale in favour of that side where there was the greatest energy on the part of the commander, and the most experience in war on the part of the troops. We have taken this battle as an illustration, because in it there was an equality in the numbers on each side such as is rarely to be found.

We do not maintain that all battles exactly resemble this, but it shows the dominant tone of most of them.

In a battle in which the forces try their strength on each other so leisurely and methodically, an excess of force on one side must make the result in its favour much more certain. And it is a fact that we may search modern military history in vain for a battle in which an army has beaten another double its own strength, an occurrence by no means uncommon in former times. Buonaparte, the greatest general of modern times, in all his great victorious battles—with one exception, that of Dresden, 1813—had managed to assemble an army superior in numbers, or at least very little inferior, to that of his opponent, and when it was impossible for him to do so, as at Leipsic, Brienne, Laon, and Belle-Alliance, he was beaten.
