It is to be noted that when a body actually awaits the attack of another up to bayonet distance (something extraordinarily rare), and the attacking troop does not falter, the first does not defend itself. This is the massacre of ancient battle.
Against unimaginative men, who retain some coolness and consequently the faculty of reasoning in danger, moral effect will be as material effect. The mere act of attack does not completely succeed against such troops. (Witness battles in Spain and Waterloo). It is necessary to destroy them, and we are better at this than they by our aptitude in the use of skirmishers and above all in the mad dash of our cavalry. But the cavalry must not be treated, until it comes to so consider itself, as a precious jewel which must be guarded against injury. There should be little of it, but it must be good.
"Seek and ye shall find" not the ideal but the best method that exists. In maneuvers skirmishers, who have some effect, are returned to ranks to execute fire in two ranks which never killed anybody. Why not put your skirmishers in advance? Why sound trumpet calls which they neither hear nor understand? That they do not is fortunate, for each captain has a different call sounded. Example: at Alma, the retreat, etc. [35]
The great superiority of Roman tactics lay in their constant endeavor to coördinate physical and moral effect. Moral effect passes; finally one sees that the enemy is not so terrible as he appeared to be. Physical effect does not. The Greeks tried to dominate. The Romans preferred to kill, and kill they did. They followed thereby the better method. Their moral effect was aided by their reliable and deadly swords.
What moral force is worth to a nation at war is shown by examples. Pichegru played the traitor; this had great influence at home and we were beaten. Napoleon came back; victory returned with him.
But at that we can do nothing without good troops, not even with a Napoleon. Witness Turenne's army after his death. It remained excellent in spite of conflict between and the inefficiency of its two leaders. Note the defensive retreat across the Rhine; the regiment in Champagne attacked in front by infantry and taken in the rear by cavalry. One of the prettiest feats of the art of war.
In modern battle, which is delivered with combatants so far apart, man has come to have a horror of man. He comes to hand to hand fighting only to defend his body or if forced to it by some fortuitous encounter. More than that! It may be said that he seeks to catch the fugitive only for fear that he will turn and fight.
Guilbert says that shock actions are infinitely rare. Here, infinity is taken in its exact mathematical sense. Guilbert reduces to nothing, by deductions from practical examples, the mathematical theory of the shock of one massed body on another. Indeed the physical impulse is nothing. The moral impulse which estimates the attacker is everything. The moral impulse lies in the perception by the enemy of the resolution that animates you. They say that the battle of Amstetten was the only one in which a line actually waited for the shock of another line charging with the bayonets. Even then the Russians gave way before the moral and not before the physical impulse. They were already disconcerted, wavering, worried, hesitant, vacillating, when the blow fell. They waited long enough to receive bayonet thrusts, even blows with the rifle (in the back, as at Inkermann). [36]
This done, they fled. He who calm and strong of heart awaits his enemy, has all the advantage of fire. But the moral impulse of the assailant demoralizes the assailed. He is frightened; he sets his sight no longer; he does not even aim his piece. His lines are broken without defense, unless indeed his cavalry, waiting halted, horsemen a meter apart and in two ranks, does not break first and destroy all formation.
With good troops on both sides, if an attack is not prepared, there is every reason to believe that it will fail. The attacking troops suffer more, materially, than the defenders. The latter are in better order, fresh, while the assailants are in disorder and already have suffered a loss of morale under a certain amount of punishment. The moral superiority given by the offensive movement may be more than compensated by the good order and integrity of the defenders, when the assailants have suffered losses. The slightest reaction by the defense may demoralize the attack. This is the secret of the success of the British infantry in Spain, and not their fire by rank, which was as ineffective with them as with us.
