DIFFERENT KINDS OF ATTACK
The most usual kinds of attack are:
Frontal Attack. This attack is delivered directly against the front of the enemy. It offers little opportunity to bring more rifles against the enemy than he can bring against you. Decisive results can only be expected when your force is larger than your opponent"s or when his is unduly extended. It is a dangerous and costly method of attacking.
Enveloping Attack. Cover the front of the enemy with sufficient force to hold his attention and, with the rest of your command, strike a flank more or less obliquely. Since your line is now longer than his, and you have more rifles in action your fire is converging while that of your enemy is diverging. Never attempt the envelopment of both flanks unless you greatly outnumber your enemy. Cooperation between the frontal and enveloping attack is essential to success. The fraction of the command that envelops the enemy is generally larger than that part in his front.
A wide turning movement is not an enveloping movement. It is dangerous because your troops are separated and can be defeated in detail. In an enveloping movement your line will usually be continuous; it simply overlaps and envelops the enemy. An enveloping attack will nearly always result locally in a frontal attack, for it will meet the enemy"s reserve. Let us repeat: do not attempt a wide turning movement. Your forces will be separated, they may not be able to a.s.sist each other, and can be defeated in detail. The tendency of a beginner is to attempt a wide turning movement. The error of dispersion is then committed.
THE ACTUAL ATTACK
Deployment. To deploy means to extend the front. When does a column extend its front or prepare to fight? When open terrain, which will probably expose the troops to hostile artillery fire, is reached. This place may be two or more miles from the enemy. What is done? Strong patrols are sent out to clear the foreground of the enemy"s patrol. The plan of the attack is inaugurated. Extra ammunition is issued. Each organization is a.s.signed its task. The organizations in the firing lines are a.s.signed objectives and move out, followed by local supports and reserves. Don"t understand that they go "as skirmishers." They usually march in column of squads. Strong combat patrols are sent out to protect each flank. This is very important even with small commands.
ADVANCING THE ATTACK
It is now necessary to advance the attack to a point where the rifle is effective, so the attacking line can gain fire superiority. The attack which halts to open fire at extreme range (over 1200 yards) is not likely to ever reach its destination (the enemy). Effort should be made to arrive within 800 yards of the enemy before opening fire. How can this be done? How can we pa.s.s over a mile or more of ground, swept or likely to be swept, first by the enemy"s artillery fire and finally by rifle fire? Answer.--By using all the cover the terrain offers (escape the enemy"s view), by using inconspicuous formations, by using such formations as to minimize the effect of the enemy"s fire. Discipline at this stage of the attack is essential. Each company in the firing line will probably start its advance upon its objective in column of squads, but taking advantage of all cover. If thick underbrush is found, squad columns would probably be used. If the enemy"s artillery fire becomes too effective platoon columns or thin lines are used, dependent upon terrain, cover and the time element. Every opportunity is taken to a.s.semble the companies and continue the advance in column of squads when cover is available. The supports, following the firing line, adopt the same methods to advance as the firing line. In this stage of the attack your own artillery will he a.s.sisting you by replying to the enemy"s artillery and infantry fire that is directed at you.
THE FIRE ATTACK
The fire attack commences when the infantry in the firing line first opens fire and it usually ends with the charge. A charge is sometimes not necessary because the enemy withdraws from his position. The fire attack does not start until the firing line cannot advance without ruinous and demoralizing losses. It should not be over 1200 yards from the enemy. At this time fire superiority must be gained. This may necessitate a steady, accurate fire for many hours. For this purpose the commander puts more men on the firing line than the enemy and then some more if necessary. Local supports are used if required. Having gained fire superiority, the advance by rushes commences, but each rush must leave behind or have in front of it enough rifles to maintain fire superiority. This determines the size of the rush. You cannot lose this fire superiority and advance; and once it is lost, hours may be required to regain it. The number of men in each rush will usually decrease as the enemy"s position is approached. If the firing line is stopped, if fire superiority is lost and cannot be regained, the firing line intrenches and holds on until darkness or until a favorable turn in the situation develops. It is suicidal to turn back. During the advance, supports move up as close to the firing line as cover will permit, adopting those formations best suited to keep down losses. They may be as close as fifty yards to the firing line. They should not be as far as 500 yards in rear of it.
THE CHARGE
There can be no rule to tell you when to charge. It may be from 25 to 400 yards. The common sense (tactical instinct) of the senior ranking officer on the firing line must tell him the psychological moment to order the charge. That moment will be when your fire has broken down the enemy"s fire, broken his resistance, and destroyed his morale. The artillery increases its range. The firing line and remaining supports fix bayonets. The former increases the rate of fire, the latter rush forward under the protection of this fire, join the firing line and give it the necessary impetus. Together they rush at the enemy"s position. No restraint is placed upon their ardor. Confidence in their ability to use the bayonet gives the charging troops the promise of success. If the charge is successful, the nearest formed bodies are sent instantly in pursuit and under cover of them the commands are reorganized, order restored, and arrangements made to resist a counter attack. If the charge is unsuccessful the artillery or any formed troops in rear cover the withdrawal.
THE THEORY OF THE DEFENSIVE
The defensive is divided into the purely pa.s.sive defense and the active defense.
The pa.s.sive defense seeks merely to delay the enemy. The results can never be other than negative. It is usually for the purpose of gaining time and most frequently used by a rear guard. Since the idea of taking up the offensive is absent, no strong reserves are held out for a counter attack; the firing line is as strong as possible from the first; every advantage is taken of obstacles, natural or artificial. The flanks must be made secure.
The active defense seeks to attack the other side at some stage of the engagement. It seeks to win and only the offensive wins. It is often necessary for a commander to a.s.sume the defensive (active) either voluntarily, in order to gain time, or to secure some advantage over the enemy; or involuntarily, as in a meeting engagement where the enemy gets a start in deployment for action or where the enemy"s attack is impetuous and without sufficient preparation. In either case the defensive force contents itself with parrying the blows of the enemy, while gathering and arranging its strength, looking and waiting for the right place and time to deliver a decisive blow which is called the counter attack. Hence, a counter attack is the offensive movement of an active defense. Its success greatly depends on being delivered with vigor and at the proper time. It may be delivered in two ways: 1st--straight to the front against a weak point in the attacking line, or 2nd--by launching the reserves against the enemy"s flank after he is fully committed to the attack. The latter method offers the greatest chances for success and the most effective results.
ADVANTAGES AND DISADVANTAGES OF THE DEFENSIVE
The defense has the following advantages over the attack:
(1) Troops attacking afford a better target than the troops on the defensive.
(2) A larger amount of ammunition is usually available.
(3) The men can shoot better because they are not fatigued by advancing.
(4) Losses will be less if good cover is secured.
DISADVANTAGES OF THE DEFENSE
(1) The defender surrenders the advantage of the initiative as the attacker can elect the point of attack and the defender must be prepared at all points.
(2) The defender must fight amidst his dead and wounded which is depressing.
(3) The defender, seeing the enemy continually advancing, becomes conscious of his inability to stop him. This is depressing to the defender and is injurious to his morale.
REQUISITES OF A GOOD DEFENSIVE POSITION
If you were looking for a good defensive position, what points would you have in mind and of these points, which would be the most important? The requisites to be sought in a good defensive position are:
"(1) A clear field of fire up to the effective range of the artillery.
"(2) Flanks that are naturally secure or that can be made so by the use of the reserves.
"(3) Extent of ground suitable to the strength of the force to occupy it.
"(4) Effective cover and concealment for the troops, especially reserves.
"(5) Good communications throughout the position.
"(6) Good lines of retreat."
--Field Service Regulations.
All of these advantages will seldom if ever be found in the position selected. The one should be taken which conforms closest to the description, but you should bear in mind that a good field of fire and effective cover, in the order named, are the most important requisites.
In tracing the lines for the trenches, avoid salients (a hill, spur, woods, etc., that juts out from the general line in the direction of the enemy). Avoid placing the fire trench on the skyline. Locate it on or below the military crest. [The crest from which you can see all the ground to the front.]
