Chapter 38

THE SERVICE OF INFORMATION

(Based on the Field Service Regulations.)

PATROLLING

=959. Patrols= are small bodies of infantry or cavalry, from two men up to a company or troop, sent out from a command at any time to gain information of the enemy and of the country, to drive off small hostile bodies, to prevent them from observing the command or for other stated objects, such as to blow up a bridge, destroy a railroad track, communicate or keep in touch with friendly troops, etc. Patrols are named according to their objects, reconnoitering, visiting, connecting, exploring, flanking patrols, etc. These names are of no importance, however, because the patrol's orders in each case determine its duties.

=960.= The size of a patrol depends upon the mission it is to accomplish; if it is to gain information only, it should be as small as possible, allowing two men for each probable message to be sent (this permits you to send messages and still have a working patrol remaining); if it is to fight, it should be strong enough to defeat the probable enemy against it. For instance, a patrol of two men might be ordered to examine some high ground a few hundred yards off the road. On the other hand, during the recent war in Manchuria a Japanese patrol of 50 mounted men, to accomplish its mission marched 1,160 miles in the enemy's country and was out for 62 days.

=961. Patrol Leaders.= (=a=) Patrol leaders, usually noncommissioned officers, are selected for their endurance, keen eyesight, ability to think quickly and good military judgment. They should be able to read a map, make a sketch and send messages that are easily understood. Very important patrols are sometimes lead by officers. The leader should have a map, watch, field glass, compass, message blank and pencils.

(=b=) The ability to lead a patrol correctly without a number of detailed orders or instructions, is one of the highest and most valuable qualifications of a noncommissioned officer. Since a commander ordering out a patrol can only give general instructions as to what he desires, because he cannot possibly forsee just what situations may arise, the patrol leader will be forced to use his own judgment to decide on the proper course to pursue when something of importance suddenly occurs. He is in sole command on the spot and must make his decisions entirely on his own judgment and make them instantly. He has to bear in mind first of all his mission--what his commander wants him to do.

Possibly something may occur that should cause the patrol leader to undertake an entirely new mission and he must view the new situation from the standpoint of a higher commander.

(=c=) More battles are lost through lack of information about the enemy than from any other cause, and it is the patrols led by noncommissioned officers who must gather almost all of this information. A battalion or squadron stands a very good chance for defeating a regiment if the battalion commander knows all about the size, position and movements of the regiment and the regimental commander knows but a little about the battalion; and this will all depend on how efficiently the patrols of the two forces are led by the noncommissioned officers.

=962.= Patrols are usually sent out from the advance party of an advance guard, the rear party of a rear guard, the outguards of an outpost, and the flank (extreme right or left) sections, companies or troops of a force in a fight, but they may be sent out from any part of a command.

The commander usually states how strong a patrol shall be.

=963. Orders or Instructions=--(=a=) The orders or instructions for a patrol must state clearly whenever possible:

1. Where the enemy is or is supposed to be.

2. Where friendly patrols or detachments are apt to be seen or encountered and what the plans are for the body from which the patrol is sent out.

3. What object the patrol is sent out to accomplish; what information is desired; what features are of special importance; the general direction to be followed and how long to stay out in case the enemy is not met.

4. Where reports are to be sent.

(=b=) It often happens that, in the hurry and excitement of a sudden encounter or other situation, there is no time or opportunity to give a patrol leader anything but the briefest instructions, such as "Take three men, corporal, and locate their (the enemy's) right flank." In such a case the patrol leader through his knowledge of the general principles of patrolling, combined with the exercise of his common sense, must determine for himself just what his commander wishes him to do.

=964. Inspection of a Patrol Before Departure.= Whenever there is time and conditions permit, which most frequently is not the case, a patrol leader carefully inspects his men to see that they are in good physical condition; that they have the proper equipment, ammunition and ration; that their canteens are full, their horses (if mounted) are in good condition, not of a conspicuous color and not given to neighing, and that there is nothing about the equipment to rattle or glisten. The patrol leader should also see that the men have nothing with them (maps, orders, letters, newspapers, etc.) that, if captured, would give the enemy valuable information. This is a more important inspection than that regarding the condition of the equipment.

Whenever possible the men for a patrol should be selected for their trustworthiness, experience and knack of finding their way in a strange country.

=965. Preparing a Patrol for the Start.= The patrol leader having received his orders and having asked questions about anything he does not fully understand, makes his estimate of the situation (See Par. 950.) He then selects the number of men he needs, if this has been left to him, inspects them and carefully explains to them the orders he has received and how he intends to carry out these orders, making sure the men understand the mission of the patrol. He names some prominent place along the route they are going to follow where every one will hasten if the patrol should become scattered.

For example: An infantry company has arrived at the town of York (See Elementary Map). Captain A, at 2 P. M., calls up Corporal B and three men of his squad.

=Captain A:= Corporal, hostile infantry is reported to be at Oxford. Nothing else has been heard of the enemy. The company remains here tonight. You will take these three men and reconnoiter about two miles north along this road (indicates the Valley Pike) for signs of a hostile advance in this direction.

Stay out until dusk.

Corporal C has been sent out that road (points east along the county road).

Send messages here. Do you understand?

=Corporal B:= Yes, sir; I am to--(here he practically repeats Captain A's orders, the three men listening). Is Corporal C to cover that hill (points toward Twin Hills)?

=Captain A:= No; you must cover that ground. Move out at once, corporal. (Corporal B quickly glances at the men and sees that they have their proper equipment.)

=Corporal B= (to his men): You heard the captain's orders. We will make for that hill (points to Twin Hills). Jones, I want you to go 150 yards in advance of me; Williams, follow me at 100 yards; Smith, you'll stay with me. Jones, you'll leave this road after crossing the creek and march on that clump of trees. I want both you and Williams to be on the alert and watch me every minute for signals. In case we become scattered, make for that hill (points to Twin Hills).

=Private Jones:= Corporal, shall I keep 150 yards from you or will you keep the correct distance?

=Corporal B:= You keep the correct distance from me. Forward, Jones.

Of course, the patrol leader makes all these preparations if he has time; but, as we have said before, there will be a great many occasions when he is required to start out so promptly that he will not have any time for the inspection described and he will have to make an estimate of the situation and give his detailed orders to the members of his patrol as they start off.

=966. Co-ordination Before Departure.= Every member of a patrol should notice for himself the direction taken and all landmarks that are passed, and every man should keep his eyes and ears open all the time. Before leaving an outpost position or other place to which it is to return, the patrol commander should "co-ordinate" himself--he should see where he is with respect to certain mountains, high buildings and other prominent objects, and after the patrol has left, he should frequently turn his head around and see what the starting point looks like from where he is. This will help him to find his way back without difficulty.

THE PRINCIPLES OF PATROLLING

=967.= Paragraphs 967 to 1015 describe the methods of leading a patrol--the points a patrol leader should fully understand. In other words, they state the principles of patrolling. When you first study this chapter, simply read over these principles without trying to memorize any of them. Whenever one of the principles is applied in the solution of any of the problems on patrolling given in this book you will generally find the number of the paragraph which states that principle enclosed in brackets. Turn back and study the paragraph referred to until you thoroughly understand its meaning and you feel sure that you know how to apply that principle whenever the occasion might arise in actual patrolling. Try to impress its common sense meaning (never the mere words) on your mind, so that when a situation arises requiring the sort of action indicated in the principle, YOU WILL NOT FAIL TO RECOGNIZE IT.

=968. Formation of Patrols.=

(=a=) Figure 1 gives some examples of various ways of forming patrols. These are merely examples for the purpose of giving a general idea of the arrangement of the men. In practice common sense must dictate to the patrol leader the best formation in each case.

(=b=) In very small patrols the leader is usually in advance where he can easily lead the patrol, though not always (See E, Figure 1.) The distance between men depends upon the character of the country and the situation. In L, Figure 1, it might be anywhere from 150 to 400 yards from the leading man to the last, the distance being greater in level or open country. Some such formation as G, Figure 1, could be used in going through high brush, woods, or over very open country.

(=c=) The men must be so arranged that each man will be within signaling distance of some member of the patrol and the escape of at least one man, in case of surprise, is certain.

It must be remembered that the patrol may have to march a long distance before it is expected that the enemy will be encountered, or it may have a mission that requires it to hurry to some distant point through very dangerous country. In such cases the patrol will probably have to follow the road in order to make the necessary speed, and it will not be possible for flankers to keep up this rate marching off the road. The formation in such cases would be something like those shown in F, II and O.

Marching off the road is always slow work, so when rapidity is essential, some safe formation for road travel is necessary, as in F, L and O.

If, from the road the country for, say one-half mile on each side, can be seen, there is absolutely no use in sending out flankers a few hundred yards from the road. Use common sense.

=969. Rate of March.= (=a=) Patrols should advance quickly and quietly; be vigilant and make all practicable use of cover. If rapid marching is necessary to accomplish the mission, then little attention can be paid to cover.

(=b=) Returning patrols, near their own lines, march at a walk, unless pressed by the enemy. A patrol should not, if possible, return over its outgoing route, as the enemy may have observed it and be watching for its return.

=970. Halts.= A patrol should be halted once every hour for about ten minutes, to allow the men to rest and relieve themselves. Whenever a halt is made one or two members of the patrol must advance a short distance ahead and keep a sharp lookout to the front and flanks.

=971. Action Upon Meeting Hostile Patrol.= If a patrol should see a hostile patrol, it is generally best to hide and let it go by, and afterwards look out for and capture any messenger that may be sent back from it with messages for the main body. And when sent back yourself with a message, be careful that the enemy does not play this trick on you--always keep your ears and eyes open.

=972. Scattered Patrols.= A scattered patrol reassembles at some point previously selected; if checked in one direction, it takes another; if cut off, it returns by a detour or forces its way through. As a last resort it scatters, so that at least one man may return with information.

Occasionally it is advisable for the leader to conceal his patrol and continue the reconnaissance with one or two men; in case of cavalry the leader and men thus detached should be well mounted. If no point of assembly was previously agreed upon, it is a good general rule to reassemble, if possible, at the last resting place.

=973. Return by Different Route.= A patrol should always make it a rule to return by a different route, as this may avoid its being captured by some of the enemy who saw it going out and are lying in wait for it.

=974. Guard Against Being Cut off.= When out patrolling always guard against being cut off. Always assume that any place that affords good cover is held by the enemy until you know that it is not, and be careful not to advance beyond it without first reconnoitering it; for, if you do, you may find yourself cut off when you try to return.

=975. Night Work.= Patrols far from their commands or in contact with the enemy, often remain out over night. In such cases they seek a place of concealment unknown to the inhabitants, proceeding thereto after nightfall or under cover. Opportunities for watering, feeding and rest must not be neglected, for there is no assurance that further opportunities will present themselves. When necessary the leader provides for subsistence by demand or purchase.

=976. Civilians:= In questioning civilians care must be taken not to disclose information that may be of value to the enemy. Strangers must not be allowed to go ahead of the patrol, as they might give the enemy notice of its approach. Patrol leaders are authorized to seize telegrams and mail matter, and to arrest individuals, reporting the facts as soon as possible.

=977. Patrol Fighting.= (=a=) A patrol sent out for information never fights unless it can only get its information by fighting or is forced to fight in order to escape. This principle is the one most frequently violated by patrol leaders, particularly in peace maneuvers. They forget their mission--the thing their commander sent them out to do--and begin fighting, thus doing harm and accomplishing no important results.

(=b=) A patrol sent out to drive off hostile detachments has to fight to accomplish its mission. Sometimes a patrol has orders both to gain information and to drive back hostile patrols. In this case it may be proper to avoid a fight at one moment and to seek a fight at another. The patrol leader must always think of his mission when deciding on the proper course to follow, and then use common sense.

=978. Signals.= The following should be clearly understood by members of a patrol:

=Enemy in sight in small numbers:= Hold the rifle above the head horizontally.

=Enemy in force:= Same as preceding, raising and lowering the rifle several times.

=Take cover:= A downward motion of the hand.

Other signals may be agreed upon before starting, but they must be simple and familiar to the men; complicated signals must be avoided. Signals must be used cautiously, so as not to convey information to the enemy.

The patrol leader should see that all his men thoroughly understand that whenever they are away from the center of the patrol they must look to the nearest man for signals at least once every minute. It should never be necessary for the patrol leader to call to a man in order to get his attention. All movements of men at a distance should be regulated by signals and the men should constantly be on the lookout for these signals.

=979. Messages.= (=a=) The most skillful patrol leading is useless unless the leader fully understands when to send a message and how to write it.

(=b=) A message, whether written or verbal, should be short and clear, resembling a telegram. If it is a long account it will take too much time to write, be easily misunderstood, and if verbal, the messenger will usually forget parts of it and confuse the remainder.

(=c=) Always state when and where things are seen or reported. If haste is required, do not use up valuable moments writing down the day of the month, etc. These data are essential as a matter of future record for formal telegrams and should be put in patrol messages only when time is abundant, but never slight the essential points of information that will give valuable help to your chief. Always try to put yourself in his place--not seeing what you see and read your message--and then ask yourself, What will he want to know?

(=d=) The exact location of the enemy should be stated; whether deployed, marching or in camp, his strength, arm of the service (cavalry, infantry or artillery), and any other detail that you think would be valuable information for your chief. In giving your location do not refer to houses, streets, etc., that your chief in the rear has no knowledge of. Give your direction and distance from some point he knows of or, if you have a map like his, you can give your map location.

(=e=) Be sure your message is accurate. This does not mean that something told you should not be reported, but it should be reported, not as a fact, but as it is--a statement by somebody else. It is well to add any information about your informant, such as his apparent honesty, the probability of his having correct information, etc.--this may help your chief.

(=f=) A message should always end with a short statement of what you are going to do next. For example: "Will remain in observation," "Will continue north," "Will work around to their rear," etc. Time permitting, the bearer of a verbal message should always be required to repeat it before leaving.

(=g=) The following is a reproduction of a message blank used in field service. The instructions on the envelope are also given. A patrol leader will usually be furnished with a pad of these blanks:

The heading "From" is filled in with the _name_ of the detachment sending the information, as "Officer's Patrol, 7th Cav". Messages sent on the same day from the same source to the same person are numbered consecutively. The address is written briefly, thus, "Commanding Officer, Outpost, 1st Brigade". In the signature the writer's surname only and rank are given.

This blank is four and a half by eight inches, including the margin on the left for binding. The back is ruled in squares and provided with scales for use in making simple sketches explanatory of the message. It is issued by the Signal Corps in blocks of forty with duplicating sheets. The regulation envelope is three by five and one fourth inches and is printed as follows:

Brown, Corporal.

=981.= A message should be sent as soon as the enemy is first seen or reported. Of course, if the enemy is actually known to be in the vicinity and his patrols have been seen, etc., you must by all means avoid wasting your men by sending them back with information about small hostile patrols or other things you know your chief is already aware of and did not specifically tell you to hunt for.

If you have properly determined in your own mind what your mission is then you will have no trouble in deciding when to send messages. For example, suppose your orders are "To reconnoiter along that ridge and determine if the enemy is present in strength," and you sight a patrol of eight men. You would waste no time or men sending back any message about the patrol, for your mission is to find out if strong bodies of the enemy are about. But suppose that while working under the above orders you located a hostile battalion of infantry--a large body of troops. In this case you would surely send a detailed message, as your mission is to determine if the enemy was present in strength.

Again, suppose that while moving towards the ridge indicated by your chief in his orders, you saw his force suddenly and heavily fired on from a new and apparently unexpected quarter, not a great distance from you, but not on the ridge referred to. You know or believe none of your patrols are out in that neighborhood. In this case you should realize instantly, without any order, that your mission had changed and you should hasten to discover the size and position of this new enemy and send the information back to your chief, first notifying him of your intended change of direction.

Never forget your mission in the excitement of leading your own little force.

=982. Absence of the Enemy.= It is frequently just as important to send a message to your chief that the enemy is not in a certain locality as it is to report his actual whereabouts. You must determine from your mission when this is the case. For example, if you were ordered "To patrol beyond that woods and see if any hostile columns are moving in that direction," and on reaching the far side of the woods you had a good view of the country for some distance beyond, it would be very important to send a message back telling your chief that you could see, say, one-half mile beyond the woods and there was no enemy in sight. This information would be of the greatest importance to him. He might feel free to move troops immediately from that vicinity to some more dangerous place. You would then continue your reconnaissance further to the front.

Suggestions for Gaining Information About the Enemy

=983. Enemy on the March.= (=a=) The patrol should observe the march of the column from a concealed position that hostile patrols or flankers are not apt to search (avoid conspicuous places). Always try to discover if one hostile detachment is followed by another--if what can be seen appears to be an advance guard of a larger body not yet in view. The distance between the detachments, their relative size, etc., is always important.

(=b=) =Estimating Strength of Column.= The strength of a column may be estimated from the length of time it takes to pass a selected point. As infantry in column of squads occupies half a yard per man, cavalry one yard per horse and artillery in single file twenty yards per gun or caisson (ammunition wagon), a selected point would be passed in one minute by 175 infantry; 110 cavalry (at a walk); 200 cavalry at a trot and 5 guns or caissons. If marching in columns of twos, take one-half of the above figures.

(=c=) =Dust.= The direction of march, strength and composition (infantry, cavalry or artillery) of a column can be closely estimated from the length and character of the cloud of dust that it makes. Dust from infantry hangs low; from cavalry it is higher, disperses more quickly, and, if the cavalry moves rapidly, the upper part of the cloud is thinner; from artillery and wagons, it is of unequal height and disconnected. The effect of the wind blowing the dust must be considered.

(=d=) =Trail of Column.= Evenly trodden ground indicates infantry; prints of horseshoes mean cavalry and deep and wide wheel tracks indicate artillery. If the trail is fresh, the column passed recently; if narrow, the troops felt secure and were marching in column of route; if broad they expected an action and were prepared to deploy. A retreating army makes a broad trail across fields, especially at the start.

Always remember that the smallest or most insignificant things, such as the number of a regiment or a discarded canteen or collar ornament, may give the most valuable information to a higher commander. For example, the markings on a discarded canteen or knapsack might prove to a general commanding an army that a certain hostile division, corps, or other force was in front of him when he thought it had not been sent into the field. The markings on the canteen would convey little or no meaning to the patrol leader, but if he realized his duty he would take care to report the facts. Cavalry patrols working far ahead of the foot troops should be most careful to observe and report on such details.

(=e=) =Reflection of Weapons.= If brilliant, the troops are marching toward you, otherwise they are probably marching away from you.

=Enemy in Position.= (=a=) If an outpost line, the patrol locates the line of sentinels, their positions, the location and strength of the outguards and, as far as possible, all troops in rear. The location of the flanks of the line, whether in a strong or weak position, is of the utmost importance. Places where the line may be most easily penetrated should be searched for and the strength and routes of the hostile patrols observed.

As outposts are usually changed at dawn this is the best time to reconnoiter their positions.

(=b=) A hostile line of battle is usually hard to approach, but its extent, where the flanks rest and whether or not other troops are in rear of these flanks, should be most carefully determined.

Information as to the flanks of any force, the character of the country on each flank, etc., is always of the greatest importance, because the flanks are the weakest portions of a line. In attacking an enemy an effort is almost always made to bring the heaviest fire or blow to bear on one of his flanks. Naturally all information about this most vulnerable part of an enemy is of great importance.

=984. Prisoners.= When a patrol is ordered to secure prisoners they should be questioned as soon as captured, while still excited and their replies can in a way be verified. Their answers should be written down (unknown to them) and sent back with them as a check on what they may say on second thought.

Prisoners should always be questioned as to the following points: What regiment, brigade, division, etc., they belong to; how long they have been in position, on the march, etc.; how much sickness in their organization; whether their rations are satisfactory; who commands their troops, etc. Always try to make the prisoners think the questions are asked out of mere curiosity.

=985. Camp Noises.= The rumble of vehicles, cracking of whips, neighing of horses, braying of mules and barking of dogs often indicate the arrival or departure of troops. If the noise remains in the same place and new fires are lighted, it is probable that reenforcements have arrived. If the noise grows more indistinct, the troops are probably withdrawing. If, added to this, the fires appear to be dying out, and the enemy seems to redouble the vigilance of the outposts, the indications of retreat are strong.

=986. Abandoned Camps.= (=a=) Indications are found in the remains of camp fires. They will show, by their degree of freshness, whether much or little time elapsed since the enemy left the place, and the quantity of cinders will give an indication of the length of time he occupied it. They will also furnish a means of estimating his force approximately, ten men being allowed to each fire.

(b) Other valuable indications in regard to the length of time the position was occupied and the time when it was abandoned may be found in the evidence of care or haste in the construction of huts or shelters, and in the freshness of straw, grain, dung or the entrails of slaughtered animals. Abandoned clothing, equipments or harness will give a clue to the arms and regiments composing a retreating force. Dead horses lying about, broken weapons, discarded knapsacks, abandoned and broken-down wagons, etc., are indications of the fatigue and demoralization of the command. Bloody bandages lying about, and many fresh graves, are evidences that the enemy is heavily burdened with wounded or sick.

=987. Flames or Smoke.= If at night the flames of an enemy's camp fires disappear and reappear, something is moving between the observer and the fires. If smoke as well as flame is visible, the fires are very near. If the fires are very numerous and lighted successively, and if soon after being lighted they go out it is probable the enemy is preparing a retreat and trying to deceive us. If the fires burn brightly and clearly at a late hour, the enemy has probably gone, and has left a detachment to keep the fires burning. If, at an unusual time, much smoke is seen ascending from an enemy's camp, it is probable that he is engaged in cooking preparatory to moving off.

If lines of smoke are seen rising at several points along a railway line in the enemy's rear, it may be surmised that the railroad is being destroyed by burning the crossties, and that a retreat is planned.

=988. Limits of vision.= (a) On a clear day a man with good vision can see:

At a distance of 9 to 12 miles, church spires and towers; At a distance of 5 to 7 miles, windmills; At a distance of 2-1/2 miles, chimneys of light color; At a distance of 2,000 yards, trunks of large trees; At a distance of 1,000 yards, single posts; At 500 yards the panes of glass may be distinguished in a window.

(b) Troops are visible at 2,000 yards, at which distance a mounted man looks like a mere speck; at 1,200 yards infantry can be distinguished from cavalry; at 1,000 yards a line of men looks like a broad belt; at 600 yards the files of a squad can be counted, and at 400 yards the movements of the arms and legs can be plainly seen.

(c) The larger, brighter or better lighted an object is, the nearer it seems. An object seems nearer when it has a dark background than when it has a light one, and closer to the observer when the air is clear than when it is raining, snowing, foggy or the atmosphere is filled with smoke. An object looks farther off when the observer is facing the sun than when he has his back to it. A smooth expanse of snow, grain fields or water makes distances seem shorter than they really are.

Suggestions for the Reconnaissance of Various Positions and Localities

=989.= Cross roads should be reconnoitered in each direction for a distance depending on how rapidly the patrol must continue on, how far from the main road the first turn or high point is, etc. The main body of the patrol usually remains halted near the crossroads, while flankers do the reconnoitering.

=990. Heights.= In reconnoitering a height, if the patrol is large enough to admit of detaching them, one or two men climb the slope on either flank, keeping in sight of the patrol, if possible. In any case, one man moves cautiously up the hill, followed by the others in the file at such distance that each keeps his predecessor in view.

=991. Defiles.= On approaching a defile, if time permits, the heights on either side are reconnoitered by flankers before the patrol enters. If the heights are inaccessible or time is urgent, the patrol passes through, in single file at double time. The same method is adopted in reconnoitering a railroad cut or sunken road.

=992. Bridges and Fords.= At a bridge or ford, the front of the patrol is contracted so as to bring all the men to the passage. The leading patrolers cross first and reconnoiter the far side to prevent the possibility of the enemy surprising the main body of the patrol as it is crossing the bridge. The patrol then crosses rapidly, and takes up a proper formation. A bridge is first examined to see that it is safe and has not been tampered with by the enemy.

=993. Woods.= The patrol enters a wood in skirmishing order, the intervals being as great as may be consistent with mutual observation and support on the part of the members of the patrol. On arriving at the farther edge of the wood, the patrol remains concealed and carefully looks about before passing out to open ground. When there is such a growth of underbrush as to make this method impracticable, and it is necessary to enter a wood by a road, the road is reconnoitered as in case of defile, though not usually at double time.

=994. Enclosures.= In reconnoitering an enclosure, such as a garden, park or cemetery, the leading patrolers first examine the exterior, to make sure that the enemy is not concealed behind one of the faces of the enclosure. They then proceed to examine the interior. Great care is taken in reconnoitering and entering an enclosure to avoid being caught in a confined or restricted space by the enemy.

=995. Positions.= In approaching a position, but one man advances (one is less liable to be detected than two or more), and he crawls cautiously toward the crest of the hill or edge of the wood or opening of the defile, while the others remain concealed in the rear until he signals them to advance.

=996. Houses.= When a house is approached by a patrol, it is first reconnoitered from a distance, and if nothing suspicious is seen, it is then approached by one or two men, the rest of the party remaining concealed in observation. If the patrol is large enough to admit of it, four men approach the house, so as to examine the front and back entrances at the same time. Only one man enters the door, the others remaining outside to give the alarm, should a party of the enemy be concealed in the house. The patrol does not remain in the vicinity of the house any longer than necessary, as information relative to its numbers and movements might be given to the enemy, if a hostile party should subsequently visit the place. Farmhouses are searched for newspapers and the inhabitants questioned. If necessary to go up to a building, wood or hill, where an enemy is likely to be concealed, run for the last couple of hundred yards, having your rifle ready for instant use, and make for some point that will afford you cover when you get close up. In the case of a building, for instance, you would make for one of the corners. Such a maneuver would probably be disconcerting to anyone who might be lying in wait for you, and would be quite likely to cause them to show themselves sooner than they intended, and thus give you a chance to turn around and get away. If they fired on you while you were approaching at a run, they would not be very likely to hit you.

=997. Villages.= (=a=) In approaching a small village one or two men are sent in to reconnoiter and one around each flank, but the main body does not enter until the scouts have reported. In small patrols of three to six men so much dispersion is not safe and only one section of the village can be reconnoitered at a time.

(=b=) If the presence of the enemy is not apparent, the patrol enters the village. A suitable formation would be in single file at proper distance, each man being on the opposite side of the street from his predecessor, thus presenting a more difficult target for hostile fire and enabling the men to watch all windows.

(=c=) If the patrol is strong enough, it seizes the postoffice, telegraph office and railroad stations, and secures all important papers, such as files of telegrams sent and received, instructions to postmasters, orders of town mayor, etc., that may be there. If the patrol is part of the advance guard, it seizes the mayor and postmaster of the place and turns them over to the commander of the vanguard with the papers seized.

(=d=) While searching a village sentinels are placed at points of departure to prevent any of the inhabitants from leaving. Tall buildings and steeples are ascended and an extensive view of the surrounding country obtained.

(=e=) At night a village is more cautiously approached by a small party than by day. The patrol glides through back alleys, across gardens, etc., rather than along the main street. If there are no signs of the enemy, it makes inquiry. If no light is seen, and it seems imprudent to rouse any of the people, the patrol watches and captures one of the inhabitants, and gets from him such information as he may possess.

(=f=) The best time for the patrol to approach a village is at early dawn, when it is light enough to see, but before the inhabitants are up. It is dangerous in the extreme for a small patrol to enter a village unless it is certain that it is not occupied by the enemy, for the men could be shot down by fire from the windows, cellarways, etc., or entrapped and captured. As a rule large towns and cities are not entered by small patrols, but are watched from the outside, as a small force can not effectively reconnoiter and protect itself in such a place.

Facts Which Should Be Obtained by Patrols Regarding Certain Objects

=998. Roads.= Their direction, their nature (macadamized, corduroy plank, dirt, etc.), their condition of repair, their grade, the nature of crossroads, and the points where they leave the main roads; their borders (woods, hedges, fences or ditches), the places at which they pass through defiles, cross heights or rivers, and where they intersect railroads, their breadth (whether suitable for column of fours or platoons, etc.).

=999. Railroads.= Their direction, gauge, the number of tracks, stations and junctions, their grade, the length and height of the cuts, embankments and tunnels.

=1000. Bridges.= Their position, their width and length, their construction (trestle, girder, etc.), material (wood, brick, stone or iron), the roads and approaches on each bank.

=1001. Rivers and Other Streams.= Their direction, width and depth, the rapidity of the current, liability to sudden rises and the highest and lowest points reached by the water, as indicated by drift wood, etc., fords, the nature of the banks, kinds, position and number of islands at suitable points of passage, heights in the vicinity and their command over the banks.

=1002. Woods.= Their situation, extent and shape; whether clear or containing underbrush; the number and extent of "clearings" (open spaces); whether cut up by ravines or containing marshes, etc.; nature of roads passing through them.

=1003. Canals.= Their direction, width and depth; condition of tow-paths; locks and means of protecting or destroying them.

=1004. Telegraphs.= Whether they follow railroads or common roads; stations, number of wires.

=1005. Villages.= Their situation (on a height, in a valley or on a plain); nature of the surrounding country; construction of the houses, nature (straight or crooked) and width of streets; means of defense.

=1006. Defiles.= Their direction; whether straight or crooked; whether heights on either side are accessible or inaccessible; nature of ground at each extremity; width (frontage of column that can pass through).

=1007. Ponds and Marshes.= Means of crossing; defensive use that might be made of them as obstacles against enemy; whether the marshy grounds are practicable for any or all arms.

=1008. Springs and Rivulets.= Nature of approaches; whether water is drinkable and abundant.

=1009. Valleys.= Extent and nature; towns, villages, hamlets, streams, roads and paths therein; obstacles offered by or in the valley, to the movement of troops.

=1010. Heights.= Whether slopes are easy or steep; whether good defensive positions are offered; whether plateau is wide or narrow; whether passages are easy or difficult; whether the ground is broken or smooth, wooded or clear.

Suggestions for Patrols Employed in Executing Demolition

(Destruction or blocking of bridges, railroads, etc.)

=1011. Patrols never execute any demolition unless specifically ordered to do so.= Demolition may be of two different characters: Temporary demolition, such as cutting telegraph wires in but a few places or merely burning the flooring of bridges, removing a few rails from a track, etc., and permanent demolition, such as cutting down an entire telegraph line, completely destroying bridges, blowing in tunnels, etc. Only temporary demolition will be dealt with in this book.

=1012. Telegraph Line.= To temporarily disable telegraph lines, connect up different wires close to the glass insulators, wrap a wire around all the wires and bury its ends in the ground (this grounds or short circuits the wire), or cut all the wires in one or two places.

=1013. Railroads.= To temporarily disable railroads remove the fish plates (the plates that join the rails together at the ends) at each end of a short section of track, preferably upon an embankment, then have as many men as available raise the track on one side until the ties stand on end and turn the section of track so that it will fall down the embankment; or, cut out rails by a charge of dynamite or gun cotton placed against the web and covered up with mud or damp clay. Eight to twelve ounces of explosive is sufficient. Or blow in the sides of deep cuts or blow down embankments. Bridges, culverts, tunnels, etc., are never destroyed except on a written order of the commander-in-chief.

=1014. Wagon Road.= (=a=) Bridges can be rendered temporarily useless by removing the flooring, or, in the case of steel bridges, by burning the flooring (if obtainable, pour tar or kerosene on flooring), particularly if there is not time to remove it.

Short culverts may sometimes be blown in.

A hastily constructed barricade across a bridge or in a cut of trees, wagons, etc, may be sufficient in some cases where only the temporary check of hostile cavalry or artillery is desired.

(=b=) The road bed may be blocked by digging trenches not less than thirty feet wide and six feet deep, but as this would take a great deal of time patrols would rarely be charged with such work.

=1015. Report on Return of Patrol.= On returning the patrol leaders should make a short verbal or written report, almost always the former, briefly recounting the movements of the patrol, the information obtained of the enemy, a description of the country passed over and of friendly troops encountered. Of course, this is not practicable when the situation is changing rapidly and a returning patrol is immediately engaged in some new and pressing duty.

Model Reports of Patrol Leaders

=1016. 1. Verbal.=

=Patrol Leader= (Corporal B): Sir, Corporal B reports back with his patrol.

=Captain A:= I received two messages from you, corporal. What else did you discover?

=Corporal B:= That was a regiment of infantry, sir, with one battalion thrown out as advance guard. The main body of two battalions went into bivouac at the crossroads and the advance guard formed an outpost line along the big creek two miles south of here.

=Captain A:= Give me an account of your movements.

=Corporal B:= We followed this main road south to the creek, where we avoided a mounted patrol moving north on the road at 1-45 P. M., and then reconnoitered the valley from a ridge west of the road. We followed the ridge south for half a mile to a point where we could see a road crossing the valley and the main road at right angles, three miles south of here. There we halted, and at 2:20 what seemed to be the point and advance party (about forty men) of an infantry advance guard appeared, marching north up this road, the head at the crossroad. I then sent you message No. 1 by Private Brown.

In fifteen minutes three companies had appeared 600 yards in rear of the advance party, and I could see a heavy, low column of dust about one-half mile further to the rear. Message No. 2 was then sent in by Privates Baker and Johnson, and to avoid several hostile patrols, I drew off further to the northwest.

The advance guard then halted and established an outpost line along the south of the creek, two miles from here. The cloud of dust proved to be two more battalions and a wagon train. These two battalions went into bivouac on opposite sides of this road at the crossroads and sent out strong patrols east and west on the crossroad. Five wagons went forward to the outpost battalion and the reserve built cook fires.

As Private Rush, here, was the only man I had left, we started back, sketching the valley, ridge and positions of the main body and outpost. Here is the sketch, sir. The fields are all cut crops or meadow.

We sighted two foot patrols from the outpost, moving north about a mile from here, one following the road and one further east.

I did not see any of our patrols.

That is all, sir.

=2. Written.=

=Report of Sergeant Wm. James' Patrol of Five Men=

Support No. 1, Outpost of 6th Inf., Near Dixon, 22 Aug. 12, 2-30 to 5 P. M.

The patrol followed the timber along the creek for one mile S. from our outguards and leaving the creek bottom moved 1/2 mile S. E. to the wooded hill (about 800 ft. high), visible from our lines.

From this hill top the valley to the east (about one mile wide) could be fairly well observed. No signs of the enemy were seen and a message, No. 1, was sent back by Private Russel.

A wagon road runs N. and S. through the valley, bordered by four or five farms with numerous orchards and cleared fields. Both slopes of the valley are heavily wooded.

The patrol then moved S. W., until it struck the macadam pike which runs N. and S., through our lines. Proceeding S. 400 yds. on this pike to a low hill a farmer, on foot, was met. Said he lived one mile further S.; was looking for some loose horses; that four hostile cavalrymen, from the east, stopped at his farm at noon, drank some milk, took oats for their horses, inquired the way to Dixon and rode off in that direction within fifteen minutes. He said they were the first hostiles he had seen; that they told nothing about themselves, and they and their horses looked in good condition. Farmer appeared friendly and honest.

The patrol then returned to our lines following the pike about two miles. Road is in good condition, low hedges and barbed wire fences, stone culverts and no bridges in the two miles. Bordering country is open and gently rolling farming country and all crops are in. A sketch is attached to this report. None of our patrols was seen.

Respectfully submitted, Wm. James, Sergeant, Co. A, 6th Infy.

Problem in Patrol Leading and Patrolling

=1017.= In studying or solving tactical problems on a map you must remember that unless you carefully work out your own solution to the problem before looking at the given solution, you will practically make no progress.

It is best, if your time permits, to write out your solutions, and when you read over the given solutions, compare the solution of each point with what you thought of that same point when you were solving the problem, and consider why you did just what you did. Without this comparison much of the lasting benefit of the work is lost.

In some of these problems both the problem and solutions are presented in dialogue form so as to give company officers examples of the best method of conducting the indoor instruction of their men in minor tactics. It also gives an example of how to conduct a tactical walk out in the country, simply looking at the ground itself, instead of a map hanging on the wall. The enlarged Elementary Map referred to in Par. 954, is supposed to be used in this instruction as well as in the war games.

Problem No. 1. (Infantry)

=1018.= The Elementary Map (scale 12 inches to the mile) being hung on the wall, about two sergeants and two squads of the company are seated in a semicircle facing it, and the captain is standing beside the map with a pointer (a barrack cleaning rod makes an excellent pointer).

=Captain:= We will suppose that our company has just reached the village of York. The enemy is reported to be in the vicinity of Boling and Oxford (he points out on the map all places as they are mentioned). We are in the enemy's country.

Corporal James, I call you up at 3 P. M. and give you these orders: "Nothing has been seen of the enemy yet. Our nearest troops are three miles south of here. Take four men from your squad and reconnoiter along this road (County Road) into the valley on the other side of that ridge over there (points to the ridge just beyond the cemetery), and see if you can discover anything about the enemy. Report back here by 5 o'clock. I am sending a patrol out the Valley Pike." Now, Corporal, state just what you would do.

=Corporal James:= I would go to my squad, fall in Privates Amos, Barlow, Sharp and Brown; see that they had full canteens; that their arms were all right; that they were not lame or sick and I would have them leave their blanket rolls, haversacks and entrenching tools with the company. (Par. 964.)

I would then give these orders (Par. 963); "We are ordered out on patrol duty. Nothing has been seen of the enemy yet. Our nearest troops are three miles south of here. We are ordered to reconnoiter along this road into the valley on the other side of that ridge, and see if we can discover anything about the enemy. Another patrol is going up the Valley Pike. Reports are to be sent here. In case we are scattered we will meet at the woods on the hill over there (indicates the clump of trees just west of Mills' farm).

"I will go ahead. Amos, follow about fifty yards behind me. Barlow, you and Sharp keep about 100 yards behind Amos, and Brown will follow you at half that distance. All keep on the opposite side of the road from the man ahead of you." (Par. 968.)

=Captain:= All right, Corporal, now describe what route you will follow.

=Corporal James:= The patrol will keep to the County Road until the crest of the ridge near the stone wall is reached, when what I see in the valley beyond will decide my route for me.

=Captain:= How about the woods west of the stone walls?

=Corporal James:= If I did not see anyone from our patrol on the Valley Pike reconnoitering there, I would give Barlow these orders just after we have examined the cemetery, when the patrol would have temporarily closed up somewhat: "Barlow, take Sharp and examine that little woods over there. Join us at the top of this hill." I would then wave to Brown to close up and would proceed to the hill top.

=Captain:= Barlow what do you do?

=Private Barlow:= I would say, "Sharp, out straight across for that woods. I will follow you." I would follow about 100 yards behind him. When he reached the edge of the woods I would signal him to halt by holding up my left hand. After I had closed up to about fifty yards I would say to him, "Go into the woods and keep me in sight." I would walk along the edge of the woods where I could see Sharp and the corporal's patrol on the road at the same time.

=Captain:= That is all right, Barlow. Corporal, you should have instructed Amos or Brown to keep close watch on Barlow for signals.

=Corporal James:= I intended to watch him myself.

=Captain:= No, you would have enough to do keeping on the alert for what was ahead of you. Now describe how you lead the patrol to the top of the hill, by the stone wall.

=Corporal James:= When I reached the crest I would hold up my hand for the patrol to halt and would cautiously advance and look ahead into the valley. If I saw nothing suspicious I would wave to the men to close up and say, "Amos, go to that high ground about 250 yards over there (indicates the end of the nose made by the 60-foot contour just north of the east end of the stone wall), and look around the country." I would keep Brown behind the crest, watching Barlow's movements.

=Captain:= Now, Corporal, Amos reaches the point you indicated and Barlow and Sharp join you. What do you do?

=Corporal James:= Can I see the Steel Bridge over Sandy Creek?

=Captain:= No, it is three-fourths of a mile away and the trees along the road by Smith's hide it. You can see the cut in the road east of the bridge and the Smith house, but the crossroads are hidden by the trees bordering the roads. You see nothing suspicious. It is a clear, sunny afternoon. The roads are dusty and the trees in full foliage. The valley is principally made up of fields of cut hay, corn stubble and meadow land.

=Corporal James:= Does Private Amos give me any information?

=Captain:= No, he makes you no signals. You see him sitting behind a bush looking northwest, down the valley.

=Corporal James:= I would say, "Barlow, head straight across to where that line of trees meets the road (indicates the point where the lane from Mills' farm joins the Chester Pike). Sharp, keep about fifty yards to my right rear." I would follow Barlow at 150 yards and when I had reached the bottom land I would wave to Amos to follow us.

=Captain:= How about Brown?

=Corporal James:= I had already given him his orders to follow as rear guard and he should do so without my telling him.

=Captain:= Amos, what do you do when you see the corporal wave to you?

=Private Amos:= I would go down the hill and join him.

=Captain:= No, you could do better than that. You are too far from the corporal for him to signal you to do much of anything except stay there or join him. You should join him, but you should not go straight down to him. You should head so as to strike the Mills' Lane about 100 yards east of the house and then go down the lane, first looking along the stone wall. In this way you save time in reconnoitering the ground near the Mills' farm and protect the patrol against being surprised by an enemy hidden by the line of trees, or the wall along the lane. You are not disobeying your orders but just using common sense in following them out and thinking about what the corporal is trying to do.

Now, Corporal, why didn't you go to the Smith house and find out if the people there had seen anything of the enemy?

=Corporal James:= You said we were in the enemy's country, sir, so I thought it best to avoid the inhabitants until I found I could not get information in any other way. I intended first to see if I could locate any enemy around here, and if not, to stop at houses on my return. In this way I would be gone before the people could send any information to the enemy about my patrol.

=Captain:= Barlow reaches the Chester Pike where the Mills' lane leaves it. You are about 150 yards in his rear. Sharp is 50 yards off to your right rear, Amos 100 yards to your left rear and Brown 50 yards behind you. Just as Barlow starts to climb over the barbed wire fence into the Chester Pike you see him drop down on the ground. He signals, "Enemy in sight." Tell me quickly what would you do?

=Corporal James:= I would wave my hand for all to lie down, and I would hasten forward, stooping over as I ran, until I was about twenty yards from him, when I would crawl forward to the fence, close by him. Just before I reached him I would ask him what he saw.

=Captain:= He replies, "There are some hostile foot soldiers coming up this road."

=Corporal James:= I would crawl forward and look.

=Captain:= You see three or four men, about 500 yards north of you, coming up the Chester Pike. They are scattered out.

=Corporal James:= I would say, "Crawl into the lane, keep behind the stone wall, watch those fellows, and work your way to that farm" (indicates the Mills' farm). I would start towards the Mills' farm myself, under cover of the trees along the lane and would wave to the other men to move rapidly west, towards the hills.

=Captain:= Why didn't you try to hide near where you were and allow the hostile men to pass?

=Corporal James:= There does not seem to be any place to hide near there that a patrol would not probably examine.

=Captain:= What is your plan now?

=Corporal James:= I want to get my patrol up to that small woods near the Mills' farm, but I hardly expect to be able to get them up to that point without their being seen. In any event, I want them well back from the road where they can lie down and not be seen by the enemy when he passes.

=Captain:= You succeed in collecting your patrol in the woods without their being seen, and you see four foot soldiers in the road at the entrance to the land. One man starts up the lane, the others remaining on the road.

=Corporal James:= I say, "Brown, go through these woods and hurry straight across to York. You should be able to see the village from the other side of the woods. Report to the captain that a hostile patrol of four foot men is working south up the valley, two miles northeast of York. We will go further north. Repeat what I have told you." (Par. 979.)

=Captain:= Why didn't you send this message before?

=Corporal James:= Because we were moving in the same direction that the messenger would have had to go, and, by waiting a very few minutes, I was able to tell whether it was a mere patrol or the point of an advance guard.

=Captain:= Do you think it correct to send a messenger back with news about a small patrol?

=Corporal James:= Ordinarily it would be wrong, but as nothing has been seen of the enemy until now, this first news is important because it proves to the Captain that the enemy really is in this neighborhood, which it seems to me is a very important thing for him to know and what my mission required me to do. (Par. 981.)

=Captain:= What are you going to do now, Corporal?

=Corporal James:= We have traveled about two miles and stopped frequently, so it must be about 4 o'clock. It is one and one-third miles back to York, where I should arrive about 5 o'clock. It would take me twenty-five minutes to go from here to York, so I have about thirty-five minutes left before 5 o'clock. This will permit me to go forward another mile and still be able to reach York on time. It is two-thirds of a mile to the Mason farm, and if the hostile patrol appears to be going on, I will start for that point. Did anyone at the Mills' farm see us?

=Captain:= No, but tell me first why you do not go along this high ground that overlooks the valley?

=Corporal James:= Because our patrol that started out the Valley Pike is probably near Twin Hills and I want to cover other country. The orchard at Mason's would obstruct my view from the hills.

=Captain:= The hostile patrol goes on south. Describe briefly your next movements.

=Corporal James:= I lead my patrol over to Mason's and, concealing two of the men so that both roads and the house can be watched, I take one man and reconnoiter around the farm yard and go up to the house to question the inhabitants. (Par. 996.)

=Captain:= You find one woman there who says some other soldiers, on foot, passed there a few minutes ago, marching south. She gives you no other information about the enemy or country.

=Corporal James:= I would send Amos over to see how deep and wide Sandy Creek is (Par. 1001.) When he returned I would take the patrol over to Twin Hills, follow the ridge south to the stone wall on the County Road, watching the valley for signs of the hostile patrol, and follow the road back to York; then make my report to the Captain, telling him where I had gone, all I had seen, including a description of the country. If I had not been hurried, I would have made a sketch of the valley. I can make a rough one after I get in. (Par. 1015.)

=Captain:= Suppose on your way back you saw hostile troops appearing on the County Road, marching west over Sandy Ridge. Would you stay out longer or would you consider that you should reach Oxford by 5 o'clock?

=Corporal James:= I would send a message back at once, and remain out long enough to find out the strength and probable intention of the new enemy.

=Captain (to one platoon of his troop of cavalry):= We will suppose that this troop has just (9 A. M.) arrived in Boling (Elementary Map) on a clear, dry, summer day. The enemy is supposed to be near Salem and we have seen several of his patrols this morning on our march south to Boling. Sergeant Allen, I call you up and give you these instructions: "Take Corporal Burt's squad (eight men) and reconnoiter south by this road (indicates the Boling-Morey house road) to Salem. I will take the troop straight south to Salem and you will join it there about 10:15. It is four and one-half miles to Salem. Start at once." (You have no map.)

=Sergeant Allen:= I would like to know just what the Captain wishes my patrol to do. (Par. 965.)

=Captain:= We will suppose that this is one of the many occasions in actual campaign where things must be done quickly. Where there is no time for detailed orders. You know that the troop has been marching south towards Salem where the enemy is supposed to be. You also know we have seen several of his patrols. I have told you what the troop is going to do, and from all this you should be able to decide what your mission is in this case. We will, therefore, consider that there is no time to give you more detailed orders, and you have to decide for yourself. Of course, if you had failed to hear just what I said, then, in spite of the necessity for haste, I would repeat my instructions to you. (Par. 963.)

=Sergeant Allen:= I would ride over to Corporal Burt's squad and lead it out of the column to the road leading to the Morey house, and say, "The troop is going on straight south to Salem, four and one-half miles away. This squad will reconnoiter south to Salem by this road, joining the troop there about 10:15. In case we become separated, make for Salem. Corporal, take Brown and form the point. I will follow with the squad about 300 yards in rear. Regulate your gait on me after you get your distance. Move out now at a trot." (Par. 963.)

After Corporal Burt had gotten 150 yards out I would say, "Carter, move out as connecting file." I would then say, "Downs, you will follow about 150 yards behind us as rear guard." When Carter had gone 150 yards down the road I would order, "=1. Forward; 2. Trot; 3. March=," and ride off at the head of the four remaining men (in column of twos.) (Par. 968.)

=Captain:= Sergeant, tell me briefly what is your estimate of the situation--that is, what sort of a proposition you have before you and how you have decided to handle it.

=Sergeant Allen:= As the enemy is supposed to be near Salem and we have already seen his patrols, I expect to encounter more patrols and may meet a strong body of the enemy, on my way to Salem. As I have no map, I cannot tell anything about the road, except that it is about four and one-half miles by the direct road the troop will follow, therefore my route will be somewhat longer. I have been given an hour and fifteen minutes in which to make the trip, so, if I move at a trot along the safer portions of the road. I will have time to proceed very slowly and cautiously along the dangerous portions. My patrol will be stretched out about 500 yards on the road, which should make it difficult for the enemy to surprise us and yet should permit my controlling the movements of the men. (Par. 968.)

I consider that my mission is to start out on this road and find my way around to Salem in about an hour and, particularly, to get word across to the Captain on the other road of anything of importance about the enemy that I may learn.

=Captain:= Very well. When you reach the cut in the road across the south nose of Hill 38, your point has almost reached the Morey house. Do you make any change in your patrol?

=Sergeant Allen:= I order, "=1. Walk, 2. MARCH=," and watch to see if the connecting file observes the change in gait and comes to a walk.

=Captain:= Suppose he does not come to a walk?

=Sergeant Allen:= I would say, "Smith, gallop ahead and tell Carter to walk and to keep more on the alert."

=Captain:= Corporal Burt, you reach the road fork at Morey's. What do you do?

=Corporal Burt:= I say, "Brown, wait here until Carter is close enough to see which way you go and then trot up to me." I would walk on down the road.

=Captain:= Wouldn't you make any inspection of the Morey house?

=Corporal Burt:= Not unless I saw something suspicious from the road. I would expect the main body of the patrol to do that.

=Captain:= Don't you make any change on account of the woods you are passing?

=Corporal Burt:= No, sir. It has very heavy underbrush and we would lose valuable time trying to search through it. A large force of the enemy would hardly hide in such a place.

=Captain:= Sergeant Allen, you reach the road fork. What do you do?

=Sergeant Allen:= I would have two men go into the Morey house to question anyone they found there. I would order one of the other two men to trot up (north) that road 200 yards and wait until I signaled to him to return. With the other man I would await the result of the inspection of the Morey house. Corporal Burt should have gone ahead without orders to the cut in the road across Long Ridge, leaving Brown half way between us. (Pars. 987 to 996.)

=Captain:= You find no one at the Morey house.

=Sergeant Allen:= I would signal the man to the north to come in. I would then order two men to "find a gate in the fence and trot up on that hill (indicating Long Ridge), and look around the country and join me down this road." (Par. 968.) I would then start south at a walk, halting at the cut to await the result of the inspection on the country from the hill.

=Captain:= Foster, you and Lacey are the two men sent up on Long Ridge. When you reach the hilltop you see four hostile cavalrymen trotting north on the Valley Pike, across the railroad track.

=Private Foster:= I signal like this (enemy in sight), and wait to see if they go on north. (Par. 978.) Do I see anything else behind or ahead of them?

=Captain:= You see no other signs of the enemy on any road. Everything looks quiet. The hostile cavalrymen pass the Baker house and continue north.

=Private Foster:= I would then take Lacey, trot down the ridge to Sergeant Allen, keeping below the crest and report, "Sergeant, We saw four hostile mounted men trotting north on the road about three-quarters of a mile over there (pointing), and they kept on north, across that road (pointing to the Brown-Baker-Oxford road). There was nothing else in sight." I would then tell him what the country to the south looked like, if he wanted to know.

=Captain:= Sergeant Allen, what do you do now?

=Sergeant Allen:= I would continue toward the Brown house at a trot. I would send no message to you as you already know there are hostile patrols about and therefore this information would be of little or no importance to you. (Par. 981.)

=Captain:= You arrive at Brown's house.

=Sergeant Allen:= I would send two men in to question the people and I would continue on at a walk. I would not send any one up the road towards Oxford as Foster has already seen that road.

=Captain:= You should have sent a man several hundred yards out the Farm Lane. (Par. 989.) If he moved at a trot it would only have taken a very short time. Continue to describe your movements.

=Sergeant Allen:= I would halt at the railroad track until I saw my two men coming on from the Brown house. I would then direct the other two men who were with me to go through the first opening in the fence to the west and ride south along that ridge (62--Lone Hill--Twin Hills' ridge) until I signaled them to rejoin. I would tell them to look out for our troop over to the east. If there were a great many fences I would not send them out until we were opposite the southern edge of that woods ahead of us. There I would send them to the high ground to look over the country, and return at once.

=Captain:= There are a great many fences west of the road and practically none east of the road to Sandy Creek. Just as you arrive opposite the southern edge of those woods and are giving orders for the two men to ride up the hill, you hear firing in the direction of Bald Knob. In the road at the foot of the south slope of Bald Knob, where the trail to the quarry starts off, you can see quite a clump of horses. You see nothing to the west of your position or towards Mason's. What do you do?

=Sergeant Allen:= I signal "RALLY" to Carter and Downs. If there is a gate nearby I lead my men through it. If not, I have them cut or break an opening in the fence and ride towards the railroad fill at a fast trot, having one man gallop ahead as point.

When we reach the fill, the point having first looked beyond it, I order, "=DISMOUNT=. Lacey, hold the horses. =1. As skirmishers along that fill, 2. MARCH.=" When Corporal Burt, Brown, Carter and Downs come up Lacey takes their horses and they join the line of skirmishers. Captain, what do I see from the fill?

=Captain:= There appear to be about twenty or thirty horses in the group. The firing seems to come from the cut in the road just north of the horses and from the clump of trees by the Quarry. You can also hear firing from a point further north on the road, apparently your troop replying to the fire from Bald Knob. You see nothing in the road south of the horses as far as Hill 42, which obstructs your view. What action do you take?

=Sergeant Allen:= I order, "=AT THE FEET OF THOSE HORSES. RANGE, 850. CLIP FIRE.="

=Captain:= What is your object in doing as you have done?

=Sergeant Allen:= I know the captain intended to go to Salem with the troop. From the fact that he is replying to the hostile fire I judge he still wishes to push south. I was ordered to reconnoiter along this road, but now a situation has arisen where the troop is being prevented or delayed in doing what was desired and I am in what appears to be a very favorable position from which to give assistance to the troop and enable them to push ahead. I am practically in rear of the enemy and within effective range of their lead horses. I therefore think my mission has at least temporarily changed and I should try and cause the twenty or thirty hostile troopers to draw off (Par. 1011). Besides, I think it is my business to find out what the strength of this enemy is and whether or not he has reinforcements coming up from Salem, and send this information to the captain. From my position I can still watch the Chester Pike.

=Captain:= After you have emptied your clips you see the enemy running down out of the cut and from among the trees mount their horses and gallop south. What do you do?

=Sergeant Allen:= I would send Foster across the creek above the trestle (south of trestle), to ride across to that road (pointing towards the cut on Bald Hill) and tell the captain, who is near there, that about thirty men were on the hill and they have galloped south, and that I am continuing towards Salem. I would have Foster repeat the message that I gave him. I would then trot back to the Chester Pike and south to Mason's, taking up our old formation.

=Captain:= You see nothing unusual at Mason's and continue south until you reach the cross roads by the Smith farm. Corporal Burt and Private Brown are near the stone bridge south of Smith's; Private Carter is half way between you and Corporal Burt; and Private Downs is 100 yards north of Smith's. You have three men with you. What do you do?

=Sergeant Allen:= What time is it now?

=Captain:= It is now 9:45 A. M.

=Sergeant Allen:= I would say, "Lacey, take Jackson and gallop as far as that cut in the road (points east) and see if you can locate the enemy or our troop in the valley beyond. I will wave my hat over my head when I want you to return." I would then say to Private Moore, "Gallop down to Corporal Burt and tell him to fall back in this direction 100 yards, and then you return here bringing the other two men with you." I would then await the result of Private Lacey's reconnaissance, sending Carter to the turn in the road 200 yards west of the cross roads.

=Captain:= Lacey, what do you do?

=Private Lacey:= I order Jackson, "Follow 75 yards behind me and watch for signals from Sergeant Allen," and I then gallop across the steel bridge and half way up the hill. I then move cautiously up to the cut and, if the fences permit, I ride up on the side of the cut, dismounting just before reaching the crest of the ridge, and walk forward until I can see into the valley beyond.

=Captain:= You see no signs of the enemy in the valley, but you see your own troop on the road by the Gibbs farm with a squad in advance in the road on Hill 42.

=Private Lacey:= I look towards Sergeant Allen to see if he is signaling. I make no signals.

=Captain:= What do you do, Sergeant?

=Sergeant Allen:= I wave my hat for Private Lacey to return. I wave to Private Downs to join me and when Private Lacey arrives I signal "ASSEMBLE" to Corporal Burt and then say, "Lacey, join Corporal Burt and tell him to follow me as rear guard. Martin, join Carter and tell him to trot west. We will follow. You stay with him." After he got started I would order, "Follow me. =1. Trot; 2. MARCH.="

=Captain:= When Private Carter reaches the crest of the ridge about one-half mile west of Smith's he signals, "Enemy in sight in large numbers," and he remains in the road with Martin fifty yards in rear. (Par. 978.)

=Sergeant Allen:= I order, "=1. Walk; 2. MARCH.= =1. Squad; 2. HALT=," and gallop up to Private Carter, dismount just before reaching the crest, give my horse up to Private Martin, and run forward.

=Captain:= Carter points out what appears to be a troop of cavalry standing in the road leading north out of York, just on the edge of the town. You see about four mounted men 200 yards out of York on your road, halted, and about the same number on the Valley Pike near where it crosses the first stream north of York. What do you do?

=Sergeant Allen:= I wait about three minutes to see if they are going to move.

=Captain:= They remain halted, the men at York appear to be dismounted.

=Sergeant Allen:= I write the following message:

Hill 1/2 mile N. E. of York, 10 A. M.

Captain X:

A hostile troop of cavalry is standing in road at YORK (west of SALEM) with squads halted on N. and N. E. roads from YORK. Nothing else seen. Will remain in observation for the present.

Allen, Sgt. (Pars. 979 and 981.)

I would give the message to Martin, who had previously brought my horse up close in rear of the crest, and would say to him, "Take this message to the captain, straight across to the road the troop is on, and turn south towards Salem if you do not see them at first. Take Lacey with you. Tell him what you have seen. He knows where the troop is." I would have Carter hold my horse, and watch the remainder of the patrol for signals, while I observed the enemy.

=Captain:= At the end of five minutes the hostile troop trots north on the Valley Pike, the patrol on your road rides across to the Valley Pike and follows the troop.

=Sergeant Allen:= I would wait until the troops had crossed the creek north of York and would then face my patrol east and trot to the cross roads at Smith's, turn south and continue to Salem, sending one man to ride up on Sandy Ridge, keeping the patrol in sight.

=Captain:= We have carried out the problem far enough. It furnishes a good example of the varying situations a patrol leader has to meet. Good judgment or common sense must be used in deciding on the proper course to follow. You must always think of what your chief is trying to do and then act in the way you think will best help him to accomplish his object. If you have carefully decided just what mission you have been given to accomplish, you cannot easily go wrong. In handling a mounted patrol you must remember that if the men become widely separated in strange country, or even in country they are fairly familiar with, they are most apt to lose all contact with each other or become lost themselves.

Problem No. 2. (Infantry)

=1019. Captain (to one platoon of his company):= We will suppose it is about half an hour before dawn. One platoon of the company is deployed as skirmishers, facing north, in the cut where the County Road crosses Sandy Ridge. It is the extreme right of a line of battle extending west along the line of the County Road. The fight was not commenced. This platoon is resting in a wheat field between the railroad and the foot of the slope of Sandy Ridge, 200 yards south of the County Road. Sergeant Allen, I call you up and give you these instructions: "The enemy's line is off in that direction (pointing northwest). Take six men and work north along the railroad until it is light enough to see; then locate the hostile line and keep me informed of their movements. I will be in this vicinity. You have a compass. Start at once." Describe briefly the formation of your patrol while it is moving in the dark.

=Sergeant Allen:= One man will lead. A second man will follow about fifteen yards in rear of him. I will follow the second man at the same distance with three more men, and the last man will be about twenty yards in rear of me. All will have bayonets fixed, loaded and pieces locked. One short, low whistle will mean, =Halt=, two short whistles will mean, =Forward=, and the word "Sandy" will be the countersign by which we can identify each other.

=Captain:= Very well. We will suppose that you reach the steel trestle over Sandy Creek just at dawn and have met no opposition and heard nothing of the enemy. On either side of Sandy Creek are fields of standing corn about six feet tall. In the present dim light you can only see a few hundred yards off.

=Sergeant Allen:= The patrol being halted I would walk forward to the leading man (Brown) and say, "Brown, take Carter and form the point for the patrol, continuing along this railroad. We will follow about 150 yards in rear." I would then rejoin the main body of the patrol and order the man in rear to follow about 75 yards in rear of us. When the point had gained its distance I would move forward with the main body, ordering one man to move along the creek bank (west bank), keeping abreast of us until I signaled to him to come in.

=Captain:= Just as you reach the northern end of the railroad fill your point halts and you detect some movement in the road to the west of you. It is rapidly growing lighter.

=Sergeant Allen:= I would move the main body by the left flank into the corn, signaling to the man following the creek to rejoin, and for the rear guard to move off the track also. I would expect Brown to do the same, even before he saw what we had done. I would then close up on the point until I could see it and, halting all the patrol, I would order Foster to take Lacey and work over towards the road to see what is there and to report back to me immediately.

=Captain:= In a few minutes Foster returns and reports, "The enemy is moving south in the road and in the field beyond, in line of squads or sections. A hostile patrol is moving southeast across the field behind us. We were not seen."

(Note: This situation could well have been led up to by requiring Private Foster to explain how he conducted his reconnaissance and having him formulate his report on the situation as given.)

=Sergeant Allen:= I would then work my patrol closer to the road, keeping Foster out on that flank, and prepare to follow south in rear of the hostile movement.

=Captain:= The information you have gained is so important that you should have sent a man back to me with a verbal message, particularly as you are in a very dangerous position, and may not be able to send a message later. While you have not definitely located the left of the enemy's line, you have apparently discovered what appears to be a movement of troops forward to form the left of the attacking line. Your action in turning south to follow the troops just reported, is proper, as you now know you are partly in rear of the hostile movement and must go south to locate the hostile flank that your mission requires you to report on.

You men must picture in your minds the appearance of the country the sergeant is operating through. His patrol is now in a field of high standing corn. Unless you are looking down between the regular rows of corn you can only see a few yards ahead of you. The road has a wire fence and is bordered by a fairly heavy growth of high weeds and bushes. The ground is dry and dusty. Sergeant, how do you conduct your movement south?

=Sergeant Allen:= As my patrol is now in a very dangerous neighborhood and very liable to be caught between two hostile lines, with a deep creek between our present position and our platoon, I think it best to move cautiously southeast until I reach the creek bank (I cannot see it from where I now am), and then follow the creek south. I think I am very apt to find the enemy's left resting on this creek. Besides, if I do not soon locate the enemy, I can hold the main body of my patrol close to the creek and send scouts in towards the road to search for the enemy. It will also be much easier to send information back to the platoon from the creek bank, as a messenger can ford it and head southeast until he strikes the railroad and then follow that straight back to our starting point. It would thus be very difficult for him to get lost.

=Captain:= You move southeast and strike the creek bank just south of the railroad trestle. You now hear artillery fire off to the west and a rifle fire to the southwest which gradually increases in volume. You see a high cloud of dust hanging over the road on the hill west of Mason's and south of this road on the north slope of the northern-most knoll of the Twin Hills, you can occasionally see the flash of a gun, artillery being discharged. There seems to be no rifle firing directly in your front.

=Sergeant Allen:= I hurriedly write the following message:

At Ry. trestle 1 mi. N. of Platoon, 5:15 A. M.

Captain X:

Can see arty. firing from position on N. slope of knoll on high ridge to W. of me, and 1/4 mi. S. of E. and W. road. Hostile line is S. of me. Have not located it. Will move S.

Allen, Sgt. (Par. 474.)

I hand this to Private Smith and say to him. "Carry this quickly to the captain. Follow the railroad back until you cross a wagon road. Our platoon should be to the west of the track just beyond the road." I also read the message to Smith and point out the hostile artillery. I have considered that I sent a message before telling about the hostile advance.

I then continue south, moving slowly and with great caution. I instruct the remaining four men that in case we are surprised to try to cross the creek and follow the railroad back to the platoon.

=Captain:= Your information about the hostile artillery position was important and should have been sent in, provided you think your description of the hostile position was sufficiently clear to be understood by an observer within your own lines.

There is some question as to the advisability of your remaining on the west bank of the creek. Still you would not be able to tell from where you were what direction the creek took, so you probably would remain on the west bank for the present.

You continue south for about 150 yards and your leading man halts, comes back to you, and reports that the corn ahead is broken and trampled, showing it has been passed over by foot troops. About the same time you hear rifle fire to your immediate front. It sounds very close.

=Sergeant Allen:= I say, "Cross this creek at once," and when we reach the other bank and the patrol forms again, we move slowly south, all the men keeping away from the creek bank, except myself, and I march opposite the two men constituting the main body.

=Captain:= About this time you detect a movement in the corn across the creek in rear of the place you have just left. You think it is a body of troops moving south. The firing in front seems to be delivered from a point about two or three hundred yards south of you and you can hear heavy firing from off in the direction of your company, a few bullets passing overhead. There are scattered trees along the creek and some bushes close to the edge.

=Sergeant Allen:= I would conceal myself close to the bank, the patrol being back, out of sight from the opposite bank, and await developments.

=Captain:= Sergeant, your patrol is in a dangerous position. The enemy will very likely have a patrol or detachment in rear and beyond his flank. This patrol would probably cross the railroad trestle and take you in rear. You should have given the last men in your patrol particular instructions to watch the railroad to the north. It would have been better if you had sent one man over to the railroad, which is only a short distance away, and had him look up and down the track and also make a hurried survey of the country from an elevated position on the fill.

I also think it would be better not to await developments where you now are, but to push south and make sure of the position of the left of the enemy's firing line, later you can devote more time to the movements in rear of the first line. You are taking too many chances in remaining where you are. I do not mean that you should leave merely because you might have some of your men killed or captured, but because if this did occur you would probably not be able to accomplish your mission. Later you may have to run a big chance of sacrificing several of your men, in order to get the desired information, which would be entirely justifiable. Tell me how your men are arranged and what your next movement would be.

=Sergeant Allen:= I have four men left, I am close to the stream's bank, under cover; two men are about 25 yards further away from the stream; Private Brown is up stream as far off as he can get and still see the other two men, and Private Foster is down stream the same distance. Both Brown and Foster are well back from the stream. The two men in the middle, the main body of the patrol, make their movements conform to mine, and Brown and Foster regulate their movements on the main body. I will move south until I can locate the enemy's advance line.

=Captain:= When you are opposite the Mason house, Brown comes back to you, having signaled halt, and reports he can see the enemy's firing line about 100 yards ahead on the other side of the stream, and that a small detachment is crossing the stream just beyond where he was. What do you do?

=Sergeant Allen:= I creep forward with Brown to verify his report. The remainder of the patrol remains in place.

=Captain:= You find everything as Brown reported. You see that the firing line extends along the southern edge of the cornfield, facing an uncultivated field covered with grass and frequent patches of weeds two or three feet high. You cannot determine how strong the line is, but a heavy fire is being delivered. You cannot see the detachment that crossed the creek south of you because of the standing corn.

=Sergeant Allen:= I crawl back to the main body, leaving Brown, and write the following message:

5/6 mi. N. of Platoon, 5:32 A. M.

Captain X:

Enemy's left rests on creek 3/4 mile to your front, along S. edge of cornfield. Creek is 5 ft. deep by 60 ft. wide. Hostile patrols have crossed the creek. Will watch their rear.

Allen, Sgt.

I give this to Private James and say, "Go over to the railroad (pointing), then turn to your right and follow the track until you cross a wagon road. Our platoon is just beyond that, on this side of the track. Give this message to the captain. Hurry."

=Captain:= You should have either read the message to James or had him read it. You should also have cautioned him to watch out for that hostile detachment. It might be better to send another man off with a duplicate of the message, as there is quite a chance that James may not get through and the message is all-important. James, you get back to the wagon road here (pointing) and find yourself in the right of your battle line, but cannot locate me or the company right away.

=Private James:= I would show the note to the first officer I saw in any event, and in this case, I would turn it over to the officer who appeared to be in command of the battalion or regiment on the right of the line, telling him what company the patrol belonged to, when we went out, etc.

=Captain:= What do you do, sergeant?

=Sergeant Allen:= I start to move north a short distance in order to find out what reenforcements are in rear of the hostile line.

=Captain:= After you have moved about 75 yards you are suddenly fired into from across the creek, and at the same time from the direction of the railroad trestle. Your men break and run east through the corn and you follow, but lose sight of them. When you cross the railroad fill you are fired on from the direction of the bridge. You finally stop behind the railroad fill on the quarry switch, where two of your men join you.

=Sergeant Allen:= I would start south to rejoin the company and report.

=Captain:= That would be a mistake. It would require a long time for a second patrol to make its way out over unknown ground, filled with hostile patrols, to a point where they could observe anything in rear of the hostile flank. You are now fairly familiar with the ground, you also know about where the hostile patrols are and you have two men remaining. After a brief rest in some concealed place nearby, you should start out again to make an effort to determine the strength of the troops in rear of the hostile flank near you, or at least remain out where you could keep a sharp lookout for any attempted turning movement by the enemy. Should anything important be observed you can send back a message and two of you remain to observe the next developments before returning. The information you might send back and the additional information you might carry back, would possibly enable your own force to avoid a serious reverse or obtain a decided victory.

Your work would be very hazardous, but it is necessary, and while possibly resulting in loss of one or two of your men, it might prevent the loss of hundreds in your main force.
