As already stated, it will, as a rule, be necessary for a distant patrol only to send in two messages daily. The first contact with the hostile infantry must always be reported. It will generally suffice if the direction of march of the enemy and the march-objective reached by him are reported. It will often be desirable to send back only a single report, setting forth the events of the day. On the other hand, the method of despatch of such messages must be most carefully prepared. During the advance of the patrol the leader must call the attention of his men, more especially from any good look-out points, to any prominent features passed. He must make marks at difficult places, and where the main roads have to be left, to assist them in finding their way back. Reports should only be sent from some point from which the despatch-riders have, at least to a certain degree, a safe route, where they will not have to pass through any hostile outposts, occupied localities, or defiles. It is highly desirable to continually instruct the patrol as to the route to the rear, and as to its conduct under special circumstances, and to give it a sketch of the road. The latter should contain not only names, which will not be of much use to the patrol, but characteristic marks which may be used as points of orientation--forked roads and the like--to assist the men in choosing the right road. Orderlies should be told the general contents of messages which they carry. It is quite out of the question that in war, and especially in hostile country, despatch-riders will be allowed to ride about free from harm, as they are unfortunately allowed to do in peace. The endeavour to send many, and often superfluous, messages by a few men always eventually leads to the sending of single horsemen as despatch-riders. Such a custom, which in war must lead to disastrous consequences, cannot be too sharply reproved. Single orderlies, in hostile country, cannot be sent, except where they know the district, and where collision with the enemy's patrols is out of the question. When long distances have to be covered, there is also the danger that a horse may succumb, or that the inhabitants may stop the man. The fact that, in the Franco-Prussian War, the custom of sending single despatch-riders proved itself generally, if not entirely, sufficient must not be regarded as of great significance, as at that time there was no question of having to reckon with the opposition of hostile cavalry. In a modern war it will certainly be different, and we may be quite sure that the cavalry of each army will strive its utmost not only to reconnoitre, but also to prevent the enemy reconnoitring. The distances to be covered, also, will be very different from those of 1870-71.
