VIPATROLS, ADVANCE AND REAR GUARDS, OUTPOSTS
Patrolling. The great importance of this work calls for the most careful instruction being given our men in this duty. It is not easy to teach, there is so little of it that can be done by thumb rule except in the simpler forms as visiting patrols. The first requisite is that the instructor know the subject thoroughly. As this work is in no sense a treatise on tactics that phase of the question will not be entered into here.
Teaching patrolling
In teaching this subject in the company the following course has been found to give good results. In the winter’s school thoroughly instruct all the non-commissioned officers and selected privates in the fundamental principles; for example, the various formations, the necessity of the leader’s determining his mission and knowing how to interpret what he sees, how to write a message, and how to decide many other questions.
Sand table work
With this oral instruction there should be work on the relief map or sand table. This latter is one of the most important aids in teaching this subject. The instructor with asmall group at the table gives a simple situation and then, turning to one of the men, gives him an order as patrol leader to make a certain patrol on the ground represented by the map. Allow a short time for the section to think it over then question the leader. First get his idea of his mission and plan of action, question the others as to what they think of it, then the instructor gives his idea or concurs in that already given by the men.
Next the leader should be required to tell what he would do up to the time of moving out, the inspection he would make, what men must have and what they must not have, all the instructions and information he would give his patrol. The other members are called on in turn to point out any errors or omissions, then this part is discussed. The leader then points out his general route and gives the formation of his patrol along this route under the supposition that no enemy is encountered. The others are questioned as to their ideas of the correctness of the leader’s decision.
The instructor should then take up the march in detail, something as follows: When you reached this point what would you do? How would you get from here to there?When you reached the bottom of this little hill what did you do? And so on, bringing out carefully and thoroughly how woods, bridges, defiles and villages are traversed, etc.
At the conclusion the instructor should go back to the start and at various points along the route have them see various hostile patrols and bodies of troops, bring out what should be done in each new situation, what messages sent, whether by one man or more, whether written or verbal, requiring in every case the reasons. The problem should be worked out once on the assumption that the patrol is in hostile territory and once as in friendly territory, the instructor bringing out clearly the difference in conduct. The mission should then be changed, as for instance from a patrol seeking information change the problem, on the same ground so as to give it a mission of screening.
The various phases of patrolling, in friendly and hostile territory, with a mission to gain information and then to prevent the enemy’s gaining it should be worked out carefully on the same ground with only the necessary changes in the problem to bring out the differences in their conduct. It seems to impress these differences on the men themore lastingly, the more closely the problems resemble each other in other respects and when they are on the same ground.
After this series is once worked through with the men, other problems on different ground are taken. It takes considerable work of this kind to make the men proficient in the principles of patrolling. As soon as they are deemed proficient they should be taken out for tactical walks in patrol problems on the ground and there given problems to solve, the instructor acting as umpire. This is all work that can be done in most posts in the winter season by taking advantage of the most favorable weather for the outdoor part.
The instruction in the principles of patrol leading can be given to better advantage on the relief map or sand table than on the ground but the latter training can not be dispensed with, some of it must be given. Later on there should be much opportunity for further practice in the course of the combat exercises.
Other kinds of patrolling
The work of the expeditionary patrol should be taught in the same manner. The work of the visiting and connecting patrols can be taught during the exercises in advance guard and outposts. They require very littleeffort. The company as a whole should be frequently exercised as a strong patrol. There is one form of patrol, often very strong, that is of great importance and yet its proper training is frequently neglected—the combat patrol. These patrols are always thrown out when a command deploys for action and upon their proper conduct much depends. Their mission is always to prevent the firing line from being unexpectedly fired into from the flank and they fulfill this mission according to the situation, either by securing the flank by themselves holding off the enemy, or by observing and giving timely warning so that the support or reserves can be disposed to meet the enemy and thus ward off the attack.
It must be thoroughly impressed on all what the mission of the combat patrol leader really means and that any position or formation of such a patrol, that allows the firing line to be so attacked is all wrong.
The combat patrol
The following must be thoroughly taught:
1. That when the patrol is so situated that it can see no more than the men on that flank of the firing line it is serving no valuable purpose.
2. That in practically all cases where itis not in advance of the firing line it will not gain the necessary information in time to be of any value.
3. That the enemy must not get within effective rifle range of the flank of the line.
The strength of the combat patrol must depend on whether it is merely to observe or to offer real resistance and its conduct must be governed accordingly.
It is believed that the principles governing this work can be best taught, after a talk in the school, by a form of tactical walk, where the instructor can devote himself to the handling of this patrol; later on it is, of course, practiced in all battle exercises.
Combat patrol tactical walk
In the conduct of such walks the instructor takes his class out as such patrol and states his problem, the firing line being represented by a few men or even entirely imaginary, its progress being announced from time to time. The instructor then acts as leader, explains what is to be done and, assuming he has a platoon, takes his first position. He conceals his platoon and has observers out covering him and so placed that any enemy approaching will be seen in time, and that he will be in the best position to meet him. The number of sentinels out and theirdistance from the main body of the platoon depend on the terrain. He then carefully points out his dispositions to the class and explains why made and assuming in turn that the enemy is approaching from each of the likely directions, how his dispositions enable him to meet fully the case. The necessity for signal communication with the commander is explained and how he has provided for it.
He then discusses the terrain with reference to the next advance. As the firing line advances where he should next go, and how get there. A small patrol advances to the next position selected, finds it unoccupied and so signals back. The platoon then moves there and sentinels are sent out as before and possibly small reconnoitering patrols. The same discussion as before. Also from time to time hostile patrols are assumed to be seen and what should be done explained; when fire would be opened on the main hostile line, if at all. In fact the whole conduct of this patrol until the conclusion of the fight should be discussed, showing how it jumps from place to place, always covered by sentinels or small patrols, and how the firing line is always protected by it from surprise. He should point out how, in most cases, a mere marching alongin a straight line would utterly fail, and impress upon the men the fact that the leader must use his head all the time.
Having gone through such an exercise once or more, the instructor solving the problem himself, he should then prepare the problem and, having stated it, call on the class to solve it step by step in the same manner. In all cases of errors in disposition the instructor assumes an enemy from a certain direction and has the class realize the error by their inability to meet the situation. The importance of keeping as many of the patrol as practicable well in hand must be emphasized.
Any combat patrol that is to offer resistance, from a squad to a company, is handled in the same way. The work of the smaller combat patrols whose duty is only to observe are likewise taught in the same way. The terrain and conditions bringing about their use instead of the larger ones make the problem easier.
The officers of the battalion should be taken on such walks by the major or some other officer. The company commander should conduct them for his lieutenants and non-commissioned officers.
The men should also be practiced in the same way, as the combat patrol or covering detachment of a defensive line. This work is simpler, the patrol generally does not move from position to position. Its mission is the same as in the attack and even more important. In the defense very much depends on the selecting of the best position for this patrol and the correct dispositions being taken.
The case must be also considered of a patrol sent out by the defense for reconnaissance or screening which in case of attack becomes the combat patrol.
In a battle line with intervals, as in the case of the enveloping attack, connecting files must be used. Their object is to keep the commanders of the subdivision informed as to how the other is progressing. This can generally be done by forming points in the line joining the two inner flanks. In some cases this will not serve. Rules for this can not be given.
Advance guard training
Advance Guard. In most commands too much of our limited field training period is devoted to work of advance and rear guards. It is important and must be taught, but if the other work which is the real foundation forthis is properly done but little more time is required outside of the maneuver exercises for training the enlisted men. Patrolling and combat form most of the work in these exercises so far as the men are concerned.
There are many tactical problems that come to the officers in this class of work and they must know how to solve them. This is the work of the school for officers and should be effectively done.
Advance guard rencontre
The point is but a patrol with a special mission. The flanking groups are reconnoitering and scouting patrols but they involve some new features. When a rencontre engagement occurs on the march one of the first things the commander wants to know is the strength of the enemy and his location; if deployed, where is his line? Where its flank? If not deployed, what is he doing? As the advance party deploys and pushes on, these flanking groups have the best opportunity to observe and by reconnaissance to gain valuable information. They also become, temporarily at least, combat patrols to the firing line. The men must be taught to carry out this mission without further orders and to do it correctly. In case small detachments attempt to delay our march, these patrols byflanking them can greatly hurry their retreat and prevent the delay of our column.
Maneuver work
The general principle of advance and rear guards should be taught the company. This work can be done in part at the relief map and sand table, but the company should be exercised on the ground as the advance guard of a battalion and as the advance party of a larger advance guard, the other troops being imaginary. Afterwards two companies should work against each other, one as rear party of a rear guard, the other as advance party of an advance guard; also each as advance party in a rencontre.
If the foundation has been properly laid there is no difficulty in teaching the application of these principles to covering detachments. If it has not been so laid and the men do not thoroughly understand patrolling in its different forms, it will be hard to teach it in these exercises.
In maneuver exercises problems involving rencontre engagements and engagements involving a marching column encountering an enemy in position should be had to train the officers in tactics and to give the men practice in combat exercises and in the patrolling necessary.
Outpost training
Outposts. The general principles of outpost duty, the duties of sentinels, the general formation of an outpost line with its subdivisions must be taught the men indoors. The officers have much to learn in school or from books on this subject. With proper preparation by all the work outside is simple.
There are a few things that need special mention:
In the instruction work have a definite situation. If the company is to be exercised as a support take an outpost order giving the situation and general location of the supports. If any detachment, including the company, is to march beyond assumed existing covering detachments, see that it is properly covered by an advance guard. Judgment must be used in this, the smaller the detachment the weaker relatively the cover. Bear in mind where the other detachments are marching and the amount of cover they afford to yours.
When starting out instruct the advance where you are going, then have it go far enough in advance of that to cover you while you are making your dispositions after you have reached your destination.
From the company down make the distributionof troops and assignment of tasks in an orderly manner, much as the guard is divided up for the post guard; do this while the detachment is still formed.
Full information of the situation should be given the men; the proper performance of their duty is impossible otherwise. Each subdivision commander must attend to this. The captain should give as much of the necessary information as practicable to the whole company, this saves time for the picket commanders and will probably result in the situation being better understood.
Outpost practice on the ground
Where the outpost line should be located and how it should be disposed varies with many conditions. It is a tactical problem that the officers must be able to solve and must learn elsewhere than on the ground in the few hours devoted to this work in troop training.
A little practice should be held by the regiment as a whole in forming outpost; one with the regiment as the outpost and one with the regiment as the whole command, one battalion forming the advance guard on the march. In the latter, a halt order should be issued and outpost formed from the advance guard battalion; when completed amarch order should be issued by which the new advance guard passes through the outpost line. The outpost should then be assembled and take its place in column.
We do this very easily in map problems; try it on the ground, especially in rather close country.
Mounted scouts
The mounted scouts. While the mounted scouts have been taken from the infantry regiment there is still with each regiment a mounted detachment of orderlies. A few mounted scouts well trained are invaluable to an infantry regiment when operating alone. The commander of an infantry regiment, if wise, will see that these orderlies are trained as scouts and then when necessary he can so use them. Their most important and frequent use will be as the mounted point and flank patrols for an advance or rear guard and for patrolling to the front of an outpost line.
To be of any value they must be well instructed in these duties as described under advance guard. Being mounted they are much more valuable than a dismounted patrol for gaining information from the flanks and getting it back to the commander in time to beof some use. These orderlies can be trained in this work without interfering materially with their instruction in the care of horses and equipment and it can be given along with instruction in horsemanship.
