It is of great importance to establish communication with the reconnoitring squadron during the night halt and to adhere closely, when it is at all possible, to any arrangements made with it. It may very easily happen, as we have seen, that the task of the reconnoitring squadron may be changed, and that it may be required to operate in new directions. It is, therefore, important that the patrols do not get lost to the squadron, but are in a position to receive fresh instructions. The patrols can also utilise this opportunity for receiving reinforcements if necessary.
The patrol may sometimes lose connection with the squadron; it will then be generally most advisable for it to remain in observation of that portion of the enemy which has been found upon the road allotted to it. If this should entail a change of direction, reports should be sent direct to that portion of the army which is assumed to be the nearest according to the general situation. This must not, however, be regarded as a hard-and-fast rule. It should rather be left to the independent decision of the officer how he will act in the particular case. Independence of judgment and of character is of the highest importance, especially when on patrol. These qualities can, however, only be effective if cavalry officers are instructed as to the conditions of modern armies and are quite clear in theory as to the duties and methods of conducting patrols. It is to be hoped that they will in future realise the obligation of applying themselves most seriously to this branch of their important duties, that they may be thoroughly prepared and capable of the greatest effort when the call to arms resounds in bloody earnest through the land.
4. Close Reconnaissance and Reconnaissance during the Fight
Within certain limits determined by the various crises of the fight the reconnoitring duties of the cavalry are continuous. As the hostile armies approach one another, distant exploration merges into close reconnaissance, and from the latter evolves the battle reconnaissance, when the heavily-charged thunder-clouds of war come into collision, and the brazen dice of battle are thrown.
Within these limits the arrangements made for reconnaissance should not require fresh dispositions, but merely supplementing as they gradually develop from strategical into tactical measures. This is a matter for consideration when detailing close patrols, as the tendency is to be too prodigal of the scanty force at disposal. When the army cavalry concentrates towards the flank of the army, the detachments of it which have been carrying out the reconnaissance against the enemy's front must be gradually relieved by the divisional cavalry. The army cavalry will only be able to assist the divisional cavalry in the close reconnaissance by the action of those portions of it which may fall back behind the front of their own army. In such a case all should be placed under a single command, to prevent useless expenditure of force and contradictory orders. Whether the divisional cavalry is to be reinforced by the army cavalry or vice versâ, or whether a separate sphere of action is to be assigned to each, must depend on circumstances.
It will, however, seldom happen that the army cavalry will fall back behind the front of its own army. It will nearly always be most advantageously placed on the flank of the army, and will therefore only have to carry out such reconnaissance as is possible from this position. Such reconnaissance, however, is generally the most important.
As already indicated, the reconnoitring squadrons will gradually fall back upon the army cavalry itself, or upon the advancing columns of the main army which will now be approaching them. The reconnoitring squadrons on the outer flank will, however, be well advised not to join themselves at once to the main body of the cavalry. They must rather seek to operate against the rear of the enemy, who is already deployed, or against his lines of advance, in order to be able to report the presence of any approaching hostile reserves as early as possible. As a single example of this, had the French at Mars la Tour acted in this manner they would very soon have discovered the approach of Wedel's Brigade and its approximate strength. They would not then have been surprised by the attack of this brigade nor would they have mistaken it for the advance-guard of the Third Army. One may well assume that after dealing with Wedel's Brigade the French would, under such circumstances, have proceeded to undertake a general offensive, and that the fortunes of the day might have been with them.
The close reconnaissance before the decisive battle must seek, above all things, to obtain an idea of the grouping of the hostile forces. Herein lie the conditions of success or failure. To this end endeavours must be made to get far round the front of the enemy and to observe as many lines of approach as possible. Rapid and distant patrol riding and the straining of every nerve must be demanded in such cases.
When the whole force is to be employed, the army cavalry must endeavour to pave the way for these patrols. If it has been possible to defeat the hostile cavalry before the decisive battle, this will be comparatively easy. Otherwise, every means must now be employed to bring about this decision and to carry it to a successful conclusion, as well as to deal with other troops which may seek to cover the enemy's flanks.
