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. The absolute strength is in strategy generally a given quantity, which the commander cannot alter. But from this it by no means follows that it is impossible to carry on a war with a decidedly inferior force. War is not always a voluntary act of state policy, and least of all is it so when the forces are very unequal: consequently, any relation of forces is imaginable in war, and it would be a strange theory of war which would wish to give up its office just where it is most wanted. However desirable theory may consider a proportionate force, still it cannot say that no use can be made of the most disproportionate. No limits can be prescribed in this respect. The weaker the force the more moderate must be the object it proposes to itself, and the weaker the force the shorter time it will last. In these two directions there is a field for weakness to give way, if we may use this expression. Of the changes which the measure of the force produces in the conduct of war, we can only speak by degrees, as these things present themselves; at present it is sufficient to have indicated the general point of view, but to complete that we shall add one more observation. The more that an army involved in an unequal combat falls short of the number of its opponents, the greater must be the tension of its powers, the greater its energy when danger presses. If the reverse takes place, and instead of heroic desperation a spirit of despondency ensues, then certainly there is an end to every art of war. If with this energy of powers is combined a wise moderation in the object proposed, then there is that play of brilliant actions and prudent forbearance which we admire in the wars of Frederick the Great.
