The other kinds of movements are such as are made with a v iew to the attainment of some particular object, or to prevent the enemy from executing some design. In marching with a view to attain sonic particular object, we must take especial care that our own parallel remains covered, and for this purpose three things must be ob served. 1. That our communications he not cut off. This role, however, may be overlooked, as long as the army carries a sufficient supply of necessaries along with it, or finds those necessaries at the place of its destina tion. 2. That the enemy do not carry any place, or de stroy any of our magazines. 3. That the enemy be not in a situation to prevent us from returning, if necessary, into our own parallel, a thing which might easily hap pen, if he were to take up a strong position between the army and our own territory.
When sufficient precautions have been taken, with re spect to the points above mentioned, movements of this kind may be made in a three-fold manner : 1 With the whole army. 2. With divisions at the 53111e time, which is called a combined movement, and is often employed in marching towards the enemy, with the view of giving battle, or to force a defile, or invest a town. 3 With divisions following each other. In every movement, two things are to he apprehended.—an attack while on the march, and an anticipation on the part of the enemy. We have already spoken of the dispositions which ought to be adopted, with a view to prevent our being attacker!' white on the march, or to render such an attack harm less ; and we shall have occasion to revert to tie same subject in a sobs.Jpient part of this article. TO prevent the enemy from anticipating us, it is necess ii y 111a •.% c should keen our design concealed ; twat our ni •Vi.'MC should he Wade with celerity ; and that prr vious at range m•rits 511.•01(1 be made for removing all olistacl s which nii.zhi obstruct or detain the army, as well as for enabling it to accomplish the march, and attain its object with saf,:ty. Secrecy, indeed, is not always consistent with t iese previous arrangements; and it will !equite nun It skill and knowledge of the country to combine both in as great a degree as possible Favourable circumstances, too, are requisite to enable us to secure the means of success by previous arrangements ; but it may some times be done by occupying sonic place or post with a detachment, or sonic file which the enemy must pass, in order to prevent the object of our movement, In this case, it is necessary that the place or post which we have occupied, or the defile, be so situated as to prevent the enemy from occupying the p )sition which he means to take up; and then all the rules which we formerly laid down, with 'respect to detachments, must be observed.
A combined movement is one, in which the divisions of the army march without being able to f trni one con tiguous ordet of battle. It is often employed, because it r sables us to execute the movement with greater rapi dity; it has the effect of diverting the attention of the enemy ; and it gives us an opportunity to make an attack in more places than one, either upon the whole of the enemy's army, or on sonic large corps, or to hem in some of his troops. In such operations, it is necessary that all the divisions of the army should be secure during the march ; and this may be the case, I. \Vhen we are certain that the enemy is ignorant of our moot went, either because it has been kept completely concealed, or becauSe all the passes have been seemed, so that we can obtain immediate intelligence of all his motions on any of the marching divisions. 2. When every (lit ision has a route which secures its retreat, in case of the ene my's approach. 3. When each division is always cer tain of finding positions on its march, which will enable it to maintain itself until others come to its assistance. 4. When the cnerny, in attacking one of our divisions, would be certain of being himself attacked by another on his flank, before he could beat the first.
The march by divisions following each other is adopt ed. when great defiles prevent the march of the whole ; when one part of the army, which can move with greater rapidity, is previously dispatched in order to se cure the means of performing the march with the whole army ; or, when we have not wholly determined upon pet forming the movement, but wish to have a start. In the first case, there must be no chance of the divisions being exposed to an attack, either in the defile itself, or in the debouche from it. In the second case, the divi sion in bliValICC must either be able to maintain its ground until the army conies to its assistance, or to make its retreat without any disadvantage to itself or the rest of the army. To which we may add, with re gard to the third case, that the dispatching the division in advance must not interfere with, far less render im possible, any other movement of the army, which may be afterwards found necessary.
