Tactically this want of numbers again affects us. If the necessity to intervene arises, not only have we better firearms against us, but relatively a larger number of troops. Each tactical advantage secured will thus exercise far less effect than formerly upon our opponent, since the fraction of the enemy's force ridden down represents a smaller proportion of his whole Army.
If an Infantry Brigade, one of a force of ten Army Corps, is annihilated, the effect is not nearly so far-reaching as if this Brigade formed part of an Army of two or even three Corps.
If in these changed relations there are obviously factors which materially limit the tactical importance of Cavalry, and which must make the solution of their strategical tasks far more difficult, on the other side we find opportunities in the probable phenomena of a future War which, though less obvious, nevertheless on investigation lead us to the conclusion that the importance of the Arm is even greater than formerly, opening for it a wider sphere of activity, and even on the battle-field revealing new chances of success.
Let us consider these opportunities more closely. The greater the pitch of nervous tension to which men are wrought up in battle, the greater the pitch of excitement reached, the more decisive will be the reaction when the flood-tide of defeat overwhelms them.
Now that all European States are straining every nerve to employ enormous masses of men from the first moment of hostilities, in order thus to gain an advantage whilst their enemy is still concentrating, and when we further consider how these exertions must increase the strain throughout the nation to the very utmost, it must be apparent that the first great decision of Arms must be of overwhelming importance. Not only the troops directly concerned, but the 'masses' behind them, find themselves for the moment involved in the consequences of victory or defeat. Hence the reaction in either direction, owing to the lower average quality of the troops, their greater numbers, the increased difficulties of moving them, and the susceptibility to congestion of their rearward communications, must be far greater and far more disastrous than hitherto under similar tactical conditions.
