=476. Supports and reserves occupying trenches vacated by firing line, to improve same.= Supports and reserves occupying intrenchments vacated by the firing line should improve them, but they must not be held back or diverted from their true missions on this account. (462)

=477. Greater detail of conduct of fire attack.= Paragraphs 346 to 354, inclusive, deal more in detail with the conduct of the fire attack. (463)

THE CHARGE

(See pars. 355-356)

=478. What fire superiority accomplishes; psychological moment for charge determined by tactical instinct.= Fire superiority beats down the enemy's fire, destroys his resistance and morale, and enables the attacking troops to close on him, but an actual or threatened occupation of his position is needed to drive him out and defeat him.

The psychological moment for the charge can not be determined far in advance. The tactical instinct of the responsible officer must decide.

(464)

=479. When, and distance over which charge should be made.=

The defenders, if subjugated by the fire attack, will frequently leave before the charge begins. On the other hand, it may be necessary to carry the fire attack close to the position and follow it up with a short dash and a bayonet combat. Hence the distance over which the charge may be made will vary between wide limits. It may be from 25 to 400 yards.

The charge should be made at the earliest moment that promises success; otherwise the full advance of victory will be lost. (465)

=480. Charge to be made with approval of commander of attacking line; battalion commanders signal commander of line when ready to charge; charge to be made simultaneously.= The commander of the attacking line should indicate his approval, or give the order, before the charge is made. Subordinate commanders, usually battalion commanders, whose troops are ready to charge, signal that fact to the commander. It may be necessary for them to wait until other battalions or other parts of the line are ready or until the necessary reserves arrive.

At the signal for the charge the firing line and nearby supports and reserves rush forward. (See pars. 355 and 356.)

The charge is made simultaneously, if possible, by all the units partic.i.p.ating therein, but once committed to the a.s.sault, battalions should be pushed with the utmost vigor and no restraint placed on the ardor of charging troops by an attempt to maintain alignment. (466)

=481. Charge not to be made without sufficient troops; reserves give impetus; avoiding too dense a ma.s.s.= Before ordering the charge the commander should see that enough troops are on hand to make it a success. Local reserves joining the firing line in time to partic.i.p.ate in the charge give it a strong impetus. Too dense a ma.s.s should be avoided. (467)

=482. Line to be strengthened by prolongation.= The line should be strengthened by prolongation, if practicable, and remaining troops kept in formation for future use; but rather than that the attack should fail, the last formed body will be sent in, unless it is very apparent that it can do no good. (468)

=483. Additional force for pursuit.= To arrive in the hostile position with a very compact firing line and a few formed supports is sufficient for a victory, but an additional force kept well in hand for pursuit is of inestimable value. (469)

=484. Premature charge to be avoided; charging without authority from the rear.= A premature charge by a part of the line should be avoided, but if begun, the other parts of the line should join at once if there is any prospect of success. Under exceptional conditions a part of the line may be compelled to charge without authority from the rear. The intention to do so should be signaled to the rear. (470)

=485. Confidence in ability to use bayonet.= Confidence in their ability to use the bayonet gives the a.s.saulting troops the promise of success. (471)

=486. Pursuing fire; disordered units not to pursue.= If the enemy has left the position when the charging troops reach it, the latter should open a rapid fire upon the retreating enemy, if he is in sight. It is not advisable for the mixed and disordered units to follow him, except to advance to a favorable firing position or to cover the reorganization of others. (472)

=487. Pursuing troops; reorganization of charging line; preparations to meet counter-attack.= The nearest formed bodies accompanying or following the charge are sent instantly in pursuit. Under cover of these troops order is restored in the charging line. If the captured position is a part of a general line or is an advanced post, it should be intrenched and occupied at once.

The exhaustion of officers and men must not cause the neglect of measures to meet a counter-attack. (473)

=488. Steps to be taken when attack receives temporary setback.= If the attack receives a temporary setback and it is intended to strengthen and continue it, officers will make every effort to stop the rearward movement and will reestablish the firing line in a covered position as close as possible to the enemy. (474)

=489. Steps to be taken if attack is abandoned.= If the attack must be abandoned, the rearward movement should continue with promptness until the troops reach a feature of the terrain that facilitates the task of checking and reorganizing them. The point selected should be so far to the rear as to prevent interference by the enemy before the troops are ready to resist. The withdrawal of the attacking troops should be covered by the artillery and by reserves, if any are available.

(See Night Operations, pars. 580-590.) (475)

PURSUIT

=490. Full fruits of victory reaped by pursuit.= To reap the full fruits of victory a vigorous pursuit must be made. The natural inclination to be satisfied with a successful charge must be overcome.

The enemy must be allowed no more time to reorganize than is positively unavoidable. (476)

=491. Parts played in pursuit by reserve, artillery, and charging troops.= The part of the reserve that is still formed or is best under control is sent forward in pursuit and vigorously attacks the enemy's main body or covering detachments wherever found.

The artillery delivers a heavy fire upon the retreating enemy; the disordered attacking troops secure the position, promptly reform and become a new reserve. (477)

=492. Strengthening of position captured, if section of general line.= If the captured position is a section of the general line, the breach should be heavily occupied, made wider, and strongly secured by drawing on all reserves in the vicinity. (478)

=493. Pursuit by parallel roads.= After the pursuit from the immediate battlefield, pursuit by parallel roads is especially effective where large commands are concerned. (479)

=494. Artillery and cavalry in pursuit.= Artillery and cavalry are very effective in pursuit. (480)

ATTACK OF FORTIFICATIONS

=495. Modifications of attack in case of fortifications.= Few modifications enter into the problem of attacking fortifications. Such as are to be considered relate chiefly to the greater time and labor of advancing, the more frequent use of darkness and the use of hand grenades to augment the fire. (481)

=496. Approaching charging point under cover of darkness.= If the enemy is strongly fortified and time permits, it may be advisable to wait and approach the charging point under cover of darkness. The necessary reconnaissance and arrangements should be made before dark.

If the charge is not to be made at once, the troops intrench the advanced position, using sand bags if necessary. Before daylight the foreground should be cleared of obstacles. (482)

=497. Charging without fire preparation.= If the distance is short and other conditions are favorable, the charge may be made without fire preparation. If made, it should be launched with spirit and suddenness at the break of day. (See Night Operations pars. 580-590.) (483)

=498. Advancing to charging point by sapping.= In siege operations troops are usually advanced to the charging point by sapping. This method, however, presupposes that an early victory is not necessary, or that it is clearly inadvisable to attempt more direct methods.

(484)

HOLDING ATTACK

=499. Requisites of the holding attack.= The holding attack must be vigorous enough to hold the enemy in position and must present a front strong enough to conceal the secondary nature of the attack.

The holding attack need have comparatively little strength in rear, but conceals the fact by a firing line not distinguishable from that of a decisive attack. (485)

=500. Post and strength of supports and reserves.= Supports and reserves are kept at short distances. Their strength is less if the object is merely to hold the enemy fast than if the object is, in addition, to compel him to use up reserves. (486)

=501. Holding attacks developing into decisive attacks.= Holding attacks which may later develop into decisive attacks should be correspondingly strong in rear. (487)

=502. Feint attacks.= All feint attacks should employ dense firing lines. Their weakness is in rear and is concealed. (488)

DEFENSE

POSITIONS AND INTRENCHMENTS

=503. Requirements of a good defensive position.= The first requirement of a good position is a clear field of fire and view to the front and exposed flanks to a distance of 600 to 800 yards or more. The length of front should be suitable to the size of the command and the flanks should be secure. The position should have lateral communication and cover for supports and reserves. It should be one which the enemy can not avoid, but must attack or give up his mission.

A position having all these advantages will rarely, if ever, be found.

The one should be taken which conforms closest to the description.
