Even the mere transference backwards of the line of strategic deployment, which in 1870 could still be carried out without serious difficulties or drawbacks, could nowadays, in view of the high tension induced by modern conditions, only be executed with extraordinary difficulty, whilst lateral displacement of such numbers is quite inconceivable. For even if the railway organization would suffice for the execution of such a design, the many other preparations in the zone of concentration can neither be moved nor improvised.

Summarizing the whole question, the conclusion, I think, must be, that only that Army which has at its disposal a great preponderance of Cavalry could allow itself the luxury of such premature commitment of its mounted forces.

In general, the difficulties of replacing the losses of the Cavalry with material of equal quality are so great that only the most important reasons could justify any such attempts. Hence the side which is weaker in Cavalry will meet the circumstances best by keeping back its horsemen, and not sacrificing its officers for infinitesimal, and probably unattainable, advantages. It will be better merely to work up to the enemy as close as may be possible without serious losses, allow the enemy's mounted forces to wreck themselves against the opposing infantry and armed population, and only then to put in its Cavalry for decisive action when the opponent has already wasted his best elements in the pursuit of insignificant advantages. After all, it is only then, when the strategical concentration commences, after railway movement is completed, that reconnaissance becomes both possible and important.

Circumstances can, of course, arise in which, already during the first period of operations, exhaustive independent activity may be demanded from the Cavalry, as, for instance, when one has reason to believe that the enemy has changed his previously-selected zone of concentration, or, as when in 1870 on the German side, it becomes necessary to take steps to protect the frontier districts against the enemy's raids. In the first case the attempts to discover, by the employment of Cavalry, the changed dispositions of the enemy are certainly permissible. The patrols must then go forward until they can settle the decisive questions, and strong detachments must be pushed out so close behind them that the patrols and their following squadrons can find a safe retreat, and insure the transmission of the intelligence they have collected.

In such enterprises tactical collision with the enemy's Cavalry and his frontier troops might ensue. It may therefore be necessary to support our squadrons by Infantry and Artillery.

But in every case we must be careful to keep within the limits which are conditioned by the purpose of the undertaking, and not allow ourselves to be involved in desperate and doubtful enterprises.

In the next case the duties of the Cavalry are merely defensive. All that then matters is to rob small bodies of the enemy of their opportunities, to block the traffic across the frontier, and to work round their patrols with our own forces; but in no case are they to attempt to obtain positive advantages by force, or to hazard important decisions against a superior enemy. Wherever possible every effort should be made to supplement the troops assigned to this defensive attitude by the armed population, or even to replace them by such levies altogether. The fortification and defence of villages and isolated farms, occupation of railways and watercourses, and, above all, the defence of woods which might favour the concealed advance of the enemy's patrols, can well be left to the care of these improvised formations.

Hostile attempts can be generally met by dismounted fire action in well-chosen strong defensive country, possibly supported by detachments of Infantry, Artillery, and 'Landsturm.' If the enemy's superiority is great, then one must retire until the equilibrium of the forces is re-established, the strategical necessity compels us to fight, or, finally, the tactical situation gives good promise of success.

One must, however, always keep this clearly before one's mind: that the essence of all Cavalry action in the opening stage of the War lies neither in this purely defensive attitude, nor in the offensive enterprises previously alluded to, by which the concentration of the enemy would be disturbed or other material successes might be achieved, but that the decisive purpose only begins when important and possible tasks can be given to the Cavalry—i.e., when the main bodies of the enemy become ready for operations.

Then it becomes our duty to screen not only the advance of our own troops and to secure to our Infantry the advantages of being able to advance undisturbed, but the climax of all these duties will be reached in the far more important duty, in the now indispensable task, of securing the widest possible sphere of intelligence.
