FOREWORD

It must be borne in mind that this book deals with principles and

examples of methods of warfare, and not fixed rules. There are no fixed

methods in warfare. Development in warfare means change of methods or

the invention of new ones to overcome military difficulties. However,

one must have knowledge of past and present methods to be ready for the

next logical step of development.

Tactics and Duties for Trench Fighting

CHAPTER I

ORGANIZATION OF THE COMPANY FOR BATTLE FORMATIONS

I. Specialists

The exigencies of modern warfare, especially of trench warfare, have

developed new infantry weapons. As there are several kinds of these

weapons to each infantry company, the men detailed to handle them must

be trained as specialists. The weapons are:

Hand grenades

Rifle grenades

Automatic-machine rifles

Rifles

The men who use these weapons are respectively known as:

Hand grenadiers

Rifle grenadiers

A. M. R. crews

Riflemen

As a consequence of the new weapons, a company is now organized on a

basis of these specialists. A typical company is patterned like that of

the French, the only difference being in the number of specialists. Each

of the four platoons of a company contains the same number of

specialists and each platoon is divided into four sections of

specialists.

Organization of a Typical Company

One lieutenant (1st and 4th platoons under 1st lieutenants; 2nd and 3rd

platoons under 2nd lieutenants).

One sergeant (second in command, assistant to platoon commander).

1st Section, 22 men

2nd Section, 12 men

3rd Section, 12 men

4th Section, 11 men

——

Total 57 men × 4 = 228 men

224 rifles

64 pistols

16 automatic rifles

Platoon—1st Section—Hand and Rifle Grenadiers

1 Sergeant, pistol and rifle.

3 Corporals, pistol and rifle.

6 Privates, 1st class, all with rifles, two of them with pistols.

12 Privates.

——

22 men.

2nd and 3rd Sections—Riflemen

2 Corporals, rifle and pistol.

3 Privates, 1st class, rifle.

7 Privates, rifle.

——

12

4th Section—Automatic Riflemen

1 Sergeant, pistol and rifle.

1 Corporal, pistol and rifle.

3 Privates, 1st class (automatic rifle gunners, including 1 extra).

6 Privates, rifle.

——

11

Officers

1 Captain.

3 First Lieutenants.

2 Second Lieutenants.

The platoon is the self-contained unit with the proper proportion of all

the different kinds of specialists for the assault. The reason for this

is that the platoon is the largest unit that one leader can control in

combat. The four platoons are alike and therefore interchangeable.

Although it is true that the specialists are particularly trained with

their own weapons, all men of the company are first trained as riflemen.

All specialists carry rifles, and if for any reason they cannot use

their special weapon they immediately become riflemen. Also every man is

trained in hand grenade throwing. This makes it possible to fill gaps in

the specialists’ ranks from the riflemen. Some men also, usually

to the number of the A. M. R. crews, must be trained to operate the

automatic-machine rifles.

The remaining supernumeraries of the company, such as mess and supply

sergeants, mechanics, cooks, buglers, etc., do not march with the

company in maneuver or combat formations. Some of the above

supernumeraries will be found in the captain’s headquarters, or tactical

group, such as the liaison agents from the platoons, orderlies, buglers,

and observers. Mess and supply sergeants, cooks, etc., remain with the

regimental train in rear, with the kitchen behind the artillery

positions. The tactical group of the captain lives in an adjoining

dugout to that of their chief in the sector. In the fight these latter

are used as messengers or observers.

II. Use of Specialists

The following table shows the evolution of infantry armament since the

beginning of the war:

At Beginning of War

Rifle and bayonet Nearly total personnel

Hand grenades Nil

Rifle grenade guns Nil

Automatic rifles Nil

Present Time

Hand grenadiers per Co. 48

Rifle grenadiers per Co. 24

Automatic rifles per Co. 16

Outside the company is the 37 mm. gun in the battalion and trench

mortars and engines, permanent equipment of the trenches.

In the Defensive

=Hand Grenades.= Hand grenades are used to produce a short-range

defensive barrage at a distance of about 30 yards in front of the

trenches. For this purpose one grenade thrower is required for from 10

to 16 yards of frontage.

They are also used to establish centers of resistance; to protect

important features of the lines, such as salients, machine gun or

automatic rifle posts, command posts, listening posts, etc.

They are used to defend a barricade in a communicating trench. In this

latter case the grenades may be thrown from a special bombing post

established for that purpose or from an adjoining trench.

=Rifle Grenades.= Rifle grenades are employed to establish a barrage at

a greater range than that of the hand grenade, being used up to as great

a distance as 300 yards. The great advantage of the rifle grenade

barrage is that it is under the control of the platoon leader and can be

called into service immediately, which is not always true of the

artillery barrage.

Several grenade rifles concentrated on a trench will stop hand grenade

throwing from the same. Rifle grenades are usually shot from the cover

trench immediately in rear of the fire trench.

=Automatic-Machine Rifles.= In the defensive the A.M.R’s are usually

employed to obtain flanking fire from the firing line, but may be used

in the cover trench and sometimes in shallow holes out in front. In

interior fighting they are used to cover stretches of communicating

trenches against an enemy that has penetrated the first line.

=Riflemen.= The riflemen are placed in the intervals between the

specialists in the firing line. They are also used as snipers and as

sentinels. These sentinels are not to be confused with watchers, who may

or may not carry rifles.

In the Offensive

=Hand Grenades.= In the offensive, hand grenades are used to reach the

enemy under cover in trenches, etc., by high-angle throwing. It is an

excellent weapon to clear out the trenches that the assaulting columns

are advancing against. The H. G. and the R. G. break the resistance, so

to speak, of the line that the attack is to capture and the assaulting

troops are to occupy and hold. The places of the hand grenadiers in the

assaulting column are seen in the diagram.

The hand grenade is the principal weapon in trench combat—that is, to

obtain progress laterally and in depth in the trenches after a breach

has been made at one point, as every foot of trench has to be fought

for. Each section of trench, between traverses, is cleared of the enemy

by throwing H. G’s into it. It is then occupied and the next section

cleared and occupied in a similar manner.

In a raid on the enemy’s trenches hand grenades are used to clear up the

particular stretch of trenches before the raiding party jumps into them.

This will be taken up in detail later.

=Rifle Grenades.= The rifle grenade in the offensive is employed

similarly to the hand grenade, to reach an enemy under cover, but at a

greater distance.

It is used to help reduce all nests of resistance that the assaulting

infantry runs up against, and when the artillery barrage is not

obtainable for that purpose.

They may be used as a barrage to cut off the retreat of a small group of

the enemy that is being attacked in front.

Rifle grenades are very useful against counterattacks, especially before

machine guns can be brought up and the defensive artillery barrage

obtained.

=The A. M. R.= The A. M. R., with its great mobility and ease of

control, makes it possible to carry this weapon in the assault and to be

used immediately the wave is halted for any reason. In this connection,

it can be instantly employed against a nest of resistance.

It is used in the assault to protect the flanks of the assaulting waves,

especially when stopped.

As the A. M. R’s are brought up in the first wave, they are immediately

available against counterattacks upon the captured position. In a

similar manner they are employed to hold ground gained until an

artillery barrage can be obtained to support it and before the machine

guns come up.

=The Riflemen.= The riflemen, with bayonets fixed, do the necessary

fighting in the interior of the enemy’s position. As was stated before,

the H. G. and the R. G. break the enemy’s resistance and the rifleman

does the hand-to-hand fighting required to occupy the objective lines of

trenches.

To make a little résumé, we may say that the best results will be

obtained by the proper combination of all of these weapons. The low

trajectory weapons (rifle, A. M. R., H. G., and the 37 mm. gun)

concentrate on everything that shows itself above the trenches; while

the high-angle missiles (H. G. and R. G.) seek out the enemy under

cover. The riflemen complete the success of the specialists by rushing

forward and occupying the enemy’s position and fighting hand to hand for

it if necessary.

III. Formations for Maneuvering this Resultant Company of Specialists

(Formation of the Platoon)

=Initial Formation.= The initial formation of the platoon in sections of

specialists as per diagram is almost self-explanatory. Each group of

specialists is in this formation under the control of its leader ready

for any maneuver.

The platoon is the attacking unit because it contains all the

specialists required for the assault. The frontage of an offensive is

composed of a series of platoons, each with a definite objective, and

each with reinforcing platoons in depth following.

[Illustration: INITIAL FORMATION OF THE PLATOON LINE OF SECTION COLUMNS]

All other formations, whether for combat or ordinary march maneuvers,

are based upon this initial formation.

=Close Order and March Formations.= From the initial formation, we pass

to the close order formations, used for parade, roll call, or the march.

(_a_) First we have the company in line, which is the habitual formation

for assembly.

(_b_) From the company in line is formed a column of fours, for

marching. The squads that are complete execute “squads right or left,”

while the remaining odd number of specialists in any section execute the

easiest movement to bring them into column of fours, sometimes with

blank files behind the rest of their section.

=Approach March.= The approach march is a name given to the formations

that the platoon in section columns takes up to minimize casualties

while crossing the zone of artillery fire.

These formations are taken up under the conditions of open warfare, or,

in the case of reinforcements, following up an attack.

The formations may be in “Line of Section Columns” or “Double Line of

Section Columns.” In the first case, each section may be in single file

or in double column; or again the first and fourth platoon section may

be in double column and the second and third sections in single file: In

the “Double Line of Section Columns” any of the formations in the

diagrams may be taken up, depending upon circumstances.

[Illustration: FORMATIONS FOR ASSEMBLY, MARCH, AND PARADE]

The interval between sections is variable, but usually the interval is

such as to give room for the proper development into line of

skirmishers.

=Skirmishers.= This formation of skirmishers is not taken up for the

assault, but under similar conditions as that of the approach march—that

is, for open warfare and for the advance of the reinforcing platoons

behind an attack.

To form the skirmish line, each section column simply deploys into line,

each man going either right or left front into line from the regular

formation of double line of section column.

If you inspect the figure, you will see that this deployment into

skirmish line gives practically the type formation of the first

reinforcing platoon in the assaulting column.

=Assaulting Formations.= In the attack the platoon forms and goes

forward in waves. A wave is not one line of men, but is composed usually

of two or three lines.

[Illustration: PLATOON IN DOUBLE LINE OF SECTION COLUMNS COMPANY

FORMATIONS FOR MANOEUVRE]

The composition of the lines of the wave depends upon the duties and

functions of the different specialists during the attack.

Let us recapitulate the functions of the specialists in order to show

the reasons for their positions in the assaulting wave.

=The First Line of the Assaulting Wave.= In this line are the

grenadiers, whose duty it is to clear the enemy out of the objective

trenches. Here also are the A. M. R’s, employed to protect the flanks of

the wave. When the wave is halted, the A. M. R’s must be available for

instant use against any nest of resistance and must therefore be in the

first line. They are also used in the captured trench to withstand an

enemy’s counterattack, which may develop within five minutes after its

capture.

=The Second Line of the First Wave.= We have here the rifle grenadiers

who help the hand grenadiers break up the enemy’s resistance and clear

the trenches of the enemy. This is done by fire of rifle grenades from

the second line. Here, also, we have all the riflemen of the platoon,

whose function it is to follow up the success of the specialists and

drive the surviving hostile men out of the trenches with the bayonet.

[Illustration: FORMATION FOR COMBAT]

=Third Line of the First Wave.= In this line we have the “trench

cleaners” or “moppers-up.” These are hand grenadiers furnished by the

reinforcing platoon and their function is to clear the enemy out of the

trenches, both laterally and in depth of the position. The assaulting

column remains above ground and continues across the position to the

objective line of trenches, which is usually the limiting objective of

the attack. The “trench cleaners” picket all entrances and exits of

dugouts to allow none of the enemy to come out after the waves have

passed and fire into the backs of the assaulting troops.

These three lines compose the first wave, and we see that the

specialists are placed in the lines in the order of their duties.

Company Drill Regulations Adopted at Fort Sheridan, Illinois, R.O.T.C.,

in Lieu of No Existing Official Regulations

Company Organization

1. For the purposes of drill and maneuver, the regiment will be

organized as follows:

(_a_) One training company, as at present constituted, will form two

platoons.

(_b_) The new organization contemplates four platoons to the company.

When, for training purposes, a complete company is necessary or

desirable, companies will be combined.

[Illustration: PLATOON PASSING FROM MANEUVER TO COMBAT FORMATION]

2. For a training company of two platoons, the 2nd in command (sergeant)

of the first platoon is the right guide; the 2nd in command of the 2nd

platoon is the left guide.

3. The platoons, in line or column, are arranged as at present.

4. The usual arrangement of a company for attack is to place two

platoons in the 1st wave and two in the 2nd wave. The two platoons in

the 1st wave are known as the assaulting platoons; the two in the 2nd

wave, as the reinforcing platoons. The normal distance between the

assaulting and reinforcing platoon is about 65 yards. Sometimes three

platoons are placed in the 1st wave and one in the 2nd wave.

5. The first wave is followed, at a distance of 15 yards, by the hand

grenadiers of the reinforcing platoon, who are sent forward by the

commander of the reinforcing platoon to act as trench cleaners or

moppers-up for the first wave. Fifty yards behind these is the remainder

of the reinforcing platoon. There are no “moppers-up” for the

reinforcing platoon.

6. The captain of a company has four liaison agents constantly with him,

one being furnished from and for each platoon. They march immediately in

rear of the captain.

7. The post of the captain is between the 1st and 2nd waves.

Platoon Organization

1. The composition of a platoon is as follows:

1 Lieutenant (1st and 4th platoons under 1st Lieutenants).

(2nd and 3rd platoons under 2nd Lieutenants).

1 Sergeant (2nd in command, assistant to platoon leader).

=First Section=—(Grenadiers).

1 Sergeant—Section Sergeant.

2 Corporals and 12 Privates—Hand Grenadiers.

1 Corporal and 6 Privates—Rifle Grenadiers.

=Second Section=—(Riflemen).

2 Corporals and 10 Privates—Riflemen.

=Third Section=—(Riflemen).

2 Corporals and 10 Privates—Riflemen.

=Fourth Section=—(Automatic Rifle).

1 Sergeant—Charge of 1 gun crew.

1 Corporal—Charge of 1 gun crew.

3 Privates, 1st Class—Gunners—1 in charge of each gun and 1 in reserve.

6 Privates—Ammunition Carriers.

2. All platoons are alike in numbers, organization, and armament.

3. When the platoon is in column of squads or in line, the post of the

platoon leader is as at present. When in line of section columns he is

normally in front of the right center section, although he may be in

front of some other section if he sees fit. In attack formation he is in

the center of his platoon between his first and second lines.

4. When the platoon is in line, the post of the 2nd in command is in

rear of the center of his platoon. In line of section columns he is in

front of the 3rd section. In attack formation he is in rear of the fight

center of the second line.

Platoon Movements

1.

1. The 1st Section (Grenadier Section) contains 15 rifle grenadiers

(including the section sergeant) and 7 hand grenadiers. When in column

of squads, the rifle grenadiers march as a squad, in rear of the hand

grenadiers. The 1st Section constitutes 3 squads, each having the No. 3

in the rear rank as a blank file. The Section Sergeant marches abreast

of the rear rank of the 2nd squad of his section. Line is formed by

executing squads right or left.

2. The 2nd Section (Riflemen Section) contains 10 privates and 2

corporals. One corporal has charge of 7 men, the other of 3 men. When in

column of squads, the section forms one complete squad and the front

rank of another. Corporals are number four. To form line at the command

“Squads left (right),” the complete squad executes “Squad left”; of the

half squad the Nos. 3 and 4 execute “Twos left”; the Nos. 1 and 2

likewise execute “Twos left,” thus placing themselves in rear of Nos. 3

and 4. To form column from line at the command “Squads right,” the Nos.

3 and 4 of the incomplete squad move forward two paces, execute “Twos

right,” and place themselves in rear of Nos. 3 and 4 of the preceding

squad; Nos. 1 and 2 move forward two paces, execute “Twos right,” and

place themselves in rear of Nos. 1 and 2 of the preceding squad.

3. The personnel, numbers and movements of the 3rd Section are identical

with those of the 2nd.

4. The 4th Section (Automatic Rifle Section) contains 1 sergeant, 1

corporal, and 9 privates (total of 11). One complete squad is formed and

2 privates are left over who march in rear of Nos. 1 and 4 of the squad.

The corporal is No. 4 of the front rank. No. 3, front and rear rank, are

the gunners. The sergeant marches abreast of the rear rank of the squad

in the line of file-closers; when line is formed, the two men left over

form one additional file on the left (right) of their sections. In

forming for attack formation, the No. 4 of the two men left over

attaches himself to the front rank gun crew and goes with them; the No.

1, to the rear rank gun crew. The sergeant remains with his gun crew if

the guns are separated, or assumes charge of both when together.

5. If the training company contains more men than are necessary to fill

the platoons as indicated above, such additional men will be carried as

riflemen and attached to the second and third sections of the platoons.

II

1. To form line of section columns from line.

The left file of each section moves straight to the front, followed by

the file next on its right, and this in turn by the other files of the

section. The section sergeants of the 1st and 4th sections place

themselves at the head of their respective sections.

2. To form line of section columns in columns of twos or fours.

“Half-squads (squads) right front into line.”

3. To form line from line of section columns.

“Sections, right front into line.”

4. To form column of squads from line of section columns.

First form line of section columns in column of squads—then “Column of

squads—1st (4th) section forward (column right or left).”

5. To form line of section columns from column of squads.

The left file of the leading section moves straight to the front,

followed by the remaining files of the squad, then by the left file of

the second squad, etc. The 2nd, 3rd, and 4th sections oblique to the

right (left) in column of squads to section interval and, when in rear

of their place, form column of files. The section may thus be marched in

echelon, or line may be formed by halting the leading section, or the

sections in rear may be double-timed to the line established by the

leading section.

6. To form line of section columns to the flank, command:

“Sections, column left (right).”

“Line of section columns.”

7. Frequently, for convenience in maneuvering, the platoon leader may,

when in line of section columns, wish to form only two columns from his

four columns. In such event he will command:

“Double sections, 1st and 4th sections forward.”

One rifle section will follow the first section. The other rifle

section, the 4th section. The rifle sections in such formation are

always in rear of the specialist sections.

8. Intervals between sections or double sections are opened and closed

by the command:

“To —— spaces extend (close).”

III

1. Attack formation is taken up from line of section columns _only_.

2. The attack formation is always in two lines. The two lines constitute

a wave.

3. Hand grenadiers and automatic riflemen are always in the first line.

The riflemen and rifle grenadiers are always in the second line in the

assaulting platoon. Rifle grenadiers may be posted in the center of the

second line, or on either flank, as the platoon leader directs.

Similarly the automatic riflemen may be in the center, on either flank,

or divided between center and flank of the first line, as the platoon

leader may direct.

4. The 1st and 2nd lines are separated by a distance of 20 paces.

5. To pass from line of section columns to attack formation, the platoon

leader commands:

“Form for attack at (_place_). Automatic rifles to center (left flank)

(right flank) (both flanks) (left and center). Rifle grenadiers to

center (left) (right).”

Only the automatic riflemen and grenadiers need be designated. The

remaining men accommodate themselves to their movements.

At the above command the 2nd and 3rd sections stand fast until the 1st

and 4th sections have cleared their front. They then move to their

places led by the corporal at the head of their respective sections.

This movement will be executed at first in quick time; as men become

more proficient, in double time and at a run.

IV

1. The arrangement of specialists in the reinforcing platoon differs

somewhat from the assaulting platoon. The hand grenadiers of the

reinforcing platoon are sent forward in two squads to follow in rear of

the 2nd line of the first wave at a distance of about 15 yards. The two

squads are abreast of each other, the section sergeant between them.

2. The rifle grenadiers of the reinforcing platoon are then moved up

into the 1st line.

3. The riflemen of the reinforcing platoon remain in the 2nd line.

4. The position of the platoon leader of the reinforcing platoon is in

front of the center of the 1st line. The position of the 2nd in command

is the same as in the assaulting platoon.
