In the first place, the opportunity will often arise for the weaker side to avoid an encounter in the open field, and, with the help of its firearm, at least to attempt behind defiles, or strong positions, to defy the enemy's superior forces. In such cases the assailant also will be compelled to have recourse to his carbine.
Further considerations reveal that in future, quite apart from encounter with the enemy's Cavalry, our own horsemen will find tasks before them which will make appeal to the rifle inevitable.
The enemy will cover his railways, and important depots by troops of the second and third class. Reinforced by the resisting power of popular levies, they will block woods, river crossings, and defiles. Even the guards of their Convoys will be amply provided with far-ranging firearms.
In the pursuit of an enemy's beaten Cavalry we shall happen upon Infantry detachments sent out to cover their retreat, or upon defiles which have been occupied for a similar purpose. Important communications will be held by strong detachments of cyclist Infantry, who will find in woods and villages protection and favourable opportunities to use their weapons.
All these means of resistance lie beyond the field of mounted action, but they must be overcome if success is to crown our efforts.
Already in reconnaissances, particularly in those directed against the enemy's communications, we shall meet with these impediments, and the same will be the case when we come to the strategical pursuit, or the protection of a retreat.[3] In the pursuit the main object is to keep the beaten enemy on the run, to give him neither peace nor rest until complete exhaustion sets in. But for the mass of the Cavalry the idea of a purely frontal pursuit should not be encouraged, for Cavalry, even when supported by several batteries, can easily be held up by any rearguard position in which a few intact troops remain.
[Footnote 3: Compare 'Cavalry Regulations,' § 376.]
The frontal pursuit must in such cases be left to the other Arms, only to be taken up again when the last resistance of the enemy is broken, and the exhaustion of our own Infantry and Horse Artillery renders further effort on their part impossible.
