This calculation, by which the conditions of modern war are compulsorily affected, makes it highly necessary that the system of supplies and rations should be carefully organized. The restoration of any destroyed railways, the construction of light railways, the organization of columns of motor transport waggons and draught animals, must be prepared by every conceivable means in time of peace, in order that in war-time the railroads may follow as closely as possible on the track of the troops, and that the columns may maintain without interruption continuous communications between the troops and the railhead. In order to keep this machinery permanently in working order, and to surmount any crisis in bringing up supplies, it is highly advisable to have an ample stock of tinned rations. This stock should, in consideration of the necessary mass-concentration, be as large as possible. Care must be taken, by the organization of trains and columns, that the stock of tinned provisions can be quickly renewed. This would be best done by special light columns, which are attached to the army corps outside the organization of provision and transport columns, and follow it at such a distance, that, if necessary, they could be soon pushed to the front by forced or night marches. There is naturally some reluctance to increase the trains of the army corps, but this necessity is unavoidable. It is further to be observed that the columns in question would not be very long, since they would mainly convey condensed foods and other provisions compressed into the smallest space.
An immense apparatus of train formations, railway and telegraph corps, and workmen must be got ready to secure the efficiency of a modern army with its millions. This is absolutely necessary, since without it the troops in modern warfare would be practically unable to move. It is far more important to be ahead of the enemy in this respect than in any other, for there lies the possibility of massing a superior force at the decisive point, and of thus defeating a stronger opponent.
However careful the preparations, these advantages can only be attained if the troop columns do not exceed the maximum strength which can be fed from the rear, if the necessary forward movement is carried out. Everything which an army corps requires for the war must be kept within these limits.
Our modern army corps without the heavy artillery of the field army corresponds roughly to this requirement. But should it be lengthened by a heavy howitzer battalion, with the necessary ammunition columns, it will considerably exceed the safe marching depth—if, that is, the necessary advance-guard distance be included. Since, also, the infantry is too weak in proportion to the space required by the artillery to deploy, it becomes advisable in the interests both of powerful attack and of operative efficiency, within the separate troop organizations to strengthen the numbers of the infantry and reduce those of the artillery.
In addition to the length of the column, the arrangement of the division is very important for its tactical efficiency. This must be such as to permit the most varied employment of the troops and the formation of reserves without the preliminary necessity of breaking up all the units. This requirement does not at all correspond to our traditional organization, and the man to insist upon it vigorously has not yet appeared, although there can be no doubt as to the inadequacy of the existing tactical organization, and suitable schemes have already been drawn up by competent officers.
The army corps is divided into two divisions, the division into two infantry brigades. All the brigades consist of two regiments. The formation of a reserve makes it very difficult for the commander to fix the centre of gravity of the battle according to circumstances and his own judgment. It is always necessary to break up some body when a reserve has to be formed, and in most cases to reduce the officers of some detachment to inactivity. Of course, a certain centre of gravity for the battle may be obtained by assigning to one part of the troops a wider and to the other a narrower space for deployment. But this procedure in no way replaces a reserve, for it is not always possible, even in the first dispositions for the engagement, to judge where the brunt of the battle will be. That depends largely on the measures taken by the enemy and the course of the battle.
Napoleon's saying, "Je m'engage et puis je vois," finds its application, though to a lessened extent, even to-day. The division of cavalry brigades into two regiments is simply a traditional institution which has been thoughtlessly perpetuated. It has not been realized that the duties of the cavalry have completely changed, and that brigades of two regiments are, in addition to other disadvantages, too weak to carry these duties out.
This bisecting system, by restricting the freedom of action, contradicts the most generally accepted military principles.
The most natural formation is certainly a tripartition of the units, as is found in an infantry regiment. This system permits the separate divisions to fight near each other, and leaves room for the withdrawal of a reserve, the formation of a detachment, or the employment of the subdivisions in lines (Treffen), for the principle of the wing attack must not be allowed to remain merely a scheme. Finally, it is the best formation for the offensive, since it allows the main body of the troops to be employed at a single point in order to obtain a decisive result there.
A special difficulty in the free handling of the troops is produced by the quite mechanical division of the artillery, who bring into action two kinds of ordnance—cannons and howitzers. These latter can, of course, be used as cannons, but have special functions which are not always required. Their place in the organization, however, is precisely the same as that of the cannons, and it is thus very difficult to employ them as their particular character demands.
