At the period referred to there is no want of instances, also of armies entering the field unusually weak in cavalry, and yet carrying off the victory. The most remarkable is the battle of Gross-gorschen. If we only count the French divisions which took part in the battle, Buonaparte was 100,000 strong, of which 5,000 were cavalry, 90,000 infantry; the Allies had 70,000, of which 25,000 were cavalry and 40,000 infantry. Thus, in place of the 20,000 cavalry on the side of the Allies in excess of the total of the French cavalry, Buonaparte had only 50,000 additional infantry when he ought to have had 100,000. As he gained the battle with that superiority in infantry, we may ask whether it was at all likely that he would have lost it if the proportions had been 140,000 to 40,000.
Certainly the great advantage of our superiority in cavalry was shown immediately after the battle, for Buonaparte gained hardly any trophies by his victory. The gain of a battle is therefore not everything,—but is it not always the chief thing?
If we put together these considerations, we can hardly believe that the numerical proportion between cavalry and infantry which has existed for the last eighty years is the natural one, founded solely on their absolute value; we are much rather inclined to think, that after many fluctuations, the relative proportions of these arms will change further in the same direction as hitherto, and that the fixed number of cavalry at last will be considerably less.
With respect to artillery, the number of guns has naturally increased since its first invention, and according as it has been made lighter and otherwise improved; still since the time of Frederick the Great, it has also kept very much to the same proportion of two or three guns per 1,000 men, we mean at the commencement of a campaign; for during its course artillery does not melt away as fast as infantry, therefore at the end of a campaign the proportion is generally notably greater, perhaps three, four, or five guns per 1,000 men. Whether this is the natural proportion, or that the increase of artillery may be carried still further, without prejudice to the whole conduct of war, must be left for experience to decide.
The principal results we obtain from the whole of these considerations, are—
1. That infantry is the chief arm, to which the other two are subordinate.
2. That by the exercise of great skill and energy in command, the want of the two subordinate arms may in some measure be compensated for, provided that we are much stronger in infantry; and the better the infantry the easier this may be done.
3. That it is more difficult to dispense with artillery than with cavalry, because it is the chief principle of destruction, and its mode of fighting is more amalgamated with that of infantry.
4. That artillery being the strongest arm, as regards destructive action, and cavalry the weakest in that respect, the question must in general arise, how much artillery can we have without inconvenience, and what is the least proportion of cavalry we require?
