The distant patrols of the divisional cavalry will therefore often be obliged, even in their advance, to avoid the main avenues of approach of the enemy, as upon them the enemy's cavalry is certain to be met with. They must use secondary roads, and as secretly as possible, a matter of considerable difficulty in unknown hostile country. To avoid possible ambush they should retire by a different road from that by which they advanced. They will very rarely be able to get under cover for the night, especially when in the enemy's country.

Such duties can only be successfully carried out, if at all, where the commander has at his disposal a number of efficient officers and under-officers, and horses trained to endurance and cross-country work. In order to be able to carry out their task properly, the men must be clever, determined horsemen, well trained in the use of their weapons and resourceful. They must also be absolutely reliable men, who will not shrink from encountering odds when necessary. In such patrols as these the cavalry spirit must be developed to its utmost.

It is a somewhat easier matter if the divisional cavalry is not confined to a purely frontal and limited area, but can reconnoitre from the head of a flank column. It will then get opportunities of obtaining observation by moving round the enemy's outer flank. It will, however, only succeed in obtaining and transmitting intelligence by wide détours, and the demands on the endurance of man and horse will be great in proportion. It is obvious how necessary it will be, under such circumstances, that the intelligence so hardly won should at least be transmitted quickly and safely. Some detachment must therefore be detailed to perform the duties of the reporting or communicating station usually formed by a reconnoitring squadron. I see nothing for it but to devote bodies of cyclists to this purpose, which can be pushed forward as reporting centres on the main avenues, and equipped, whenever possible, with the light-signal apparatus. A few mounted men must be sent with them for scouting purposes. Without these, they would be confined to the roads for the close reconnaissance of the surrounding country, a procedure which would not suffice in the face of a determined enemy, especially in difficult country.

Besides the distant reconnaissance, the close reconnaissance along by far the greater part of the front of the army falls to the lot of the divisional cavalry. As we have seen, the army cavalry will only in exceptional cases be able to support it in this task as, on the near approach of the enemy, it will probably have occasion to draw off to a flank. But nowadays this close reconnaissance appears, by reason of the increased distances and the greater range of firearms, to have become considerably more difficult. Hostile armies move to battle nowadays on a front of 50 to 100 miles.

That it has naturally become much more difficult under such circumstances to estimate the enemy's strength and to obtain the necessary knowledge of his dispositions and of the ground, no further proof is needed. It thus becomes possible for the cavalryman in general to get no closer to the enemy than his rifle will carry, and to be compelled to observe him from a distance. There should be no mistake about this.

The importance of observation has grown in proportion to its difficulty. Troops nowadays have to be deployed for the fight at long ranges, where it is practically out of the question that a commander will be able to survey the enemy and the country with his own eyes, as was formerly almost invariably the case. Should, for example, the opponents be advancing towards each other and still 5 miles apart, another 1¼ miles will bring them into effective artillery range of each other. If they are going to wait to deploy until they reach this point, the deployment will have to be completed under the fire of the enemy's guns, a thing which, of all others, is to be avoided. It therefore follows that in a battle of encounter deployment should take place, at the latest, when still 5 miles distant from the enemy. It is better to begin to draw the forces apart even earlier, so that the army is already deployed when it moves into the range of the enemy's shrapnel.

Under these circumstances it will usually be quite impossible for the leader to make his dispositions according to his personal observations. He is, rather, almost entirely dependent in his appreciation of the enemy on the reconnaissance of the cavalry, and may find himself at a great disadvantage if this should fail or lead him to erroneous conclusions.

Reports as to the character of the country, suitable positions for artillery, decisive localities or points, thus increase greatly in importance, and it is obviously most necessary for cavalry officers to be able judiciously to appreciate such matters and to report them clearly and intelligibly. The tactical conduct, and at the same time tactical success, will often be as dependent on the tactical reconnaissance of the divisional cavalry as the strategical measures of the commander-in-chief are upon the results of the strategical exploration of the army cavalry.

Tactically and strategically the service of the divisional cavalry is of equal importance if it belongs to a force operating independently. In such cases it will often be obliged to move with more freedom than when employed in purely frontal reconnaissance with the main army. For rest, also, it will not always be able to seek the protection of the infantry, but will frequently have to be pushed out for the night on the flanks, in order to secure the main body while at rest from these directions, or the better to observe the enemy. It should, however, never lose its immediate connection with its force, and will therefore not always be in a position to measure its strength with any hostile cavalry that may be met during the period of reconnaissance.

When the tactical decision is in prospect, or when contact has been gained between the opposing forces, the divisional cavalry must redouble its efforts in reconnaissance. It is then a matter for it to reconnoitre from the flanks, and such reconnaissance can only be successful, as in the case of the army cavalry, if those portions of the country are occupied from which it is possible to observe the movements and dispositions of the enemy.
