In order to be able to deal with the functions of the mounted arm in accordance with the old Prussian principles, we must try to get a clear and unprejudiced conception of the spirit of the modern cavalry combat. We must look forward and pierce the veil of the future uninfluenced by the ghosts of the past. The probable events and conditions of the modern battle must be our guiding star, and when we have realised how the spirit of cavalry may be adapted to them, how the results of modern technical improvements in arms influence and strengthen the action of the cavalry masses, then alone can we lay down principles for the conduct and tactics of cavalry in the fight. II. ATTACK AND DEFENCE Mobility is that prominent characteristic of the cavalry on which the justification of its existence is chiefly based. That it is able to come into action rapidly at distant points, and to observe the enemy while still afar off, makes it indispensable in the composition of an army. Anything that hinders its free mobility militates against its purpose and its characteristics. Nothing, therefore, is more justifiable or more in accordance with its spirit than that it should endeavour to preserve its mobility in the fight, and that mounted shock action, therefore, should be regarded as its proper rôle in battle. In this rôle, cavalry is able not only to force a decision quickly, but to continue its movement mounted, even from the fight itself. These advantages, inherent in the nature of the arm, must not be expected in dismounted action. Such action always entails delay and hampers the movements of the troops, not only by the method of operation, but also by the separation of the men from their horses. It is therefore natural that cavalry should only undertake an attack on foot when there is no prospect of obtaining their object by shock action, or when the latter would entail such sacrifice that it might imperil the further successful action of the troops. The more, however, the disadvantageous factors of dismounted action are realised and appreciated, the more, in my opinion, will endeavours be made to give it an offensive character, in order to remove as quickly as possible obstacles which hinder the free movement of the cavalry. All delay and hesitation are in opposition to the very spirit of the arm. To preserve its peculiar element of mobility a rapid decision is imperative in every situation.
