Positions, Military

The sites occupied by armies, either for the purpose of covering and defending certain tracts of country, or preparatory to the commencement of offensive operations against an enemy. A position is considered as advantageously chosen when it is on elevated ground; when it is not commanded by eminences within the range of artillery; and when, from the existence of natural obstacles, as rivers or marshes, on the wings, it is incapable of being turned,—that is, the enemy cannot, without making an extensive movement, get to the rear of the army by which the position is occupied. In the event of such points of support being wanting, the position, whether it be a plain or an eminence, should have its flanks protected by villages, or by redoubts raised for the purpose. A village, or even a single building, on the ground occupied by the army, may become the key of the position; and as, not unfrequently, on the preservation of this point depends the field of battle, such point should be well supported by troops and artillery. The highest point of ground, particularly if near the lines of operation, may also constitute the key, and is usually strengthened by one or more redoubts. Artillery should always be placed where it can act with the most effect; and when the ground occupied by an army presents alternately salient and retired points along the front of the line, the batteries should be placed at such points. Infantry may occupy any kind of ground, but should, if po ible, always form a close line. It is usually placed between the batteries; and if exposed to a distant cannonade, the troops may be drawn up in a trench, the earth from which will serve to cover them without preventing them from marching out in line to meet the enemy. Cavalry must be posted on a level plain, over which it may advance with regularity when a charge is to be made; if compelled to act on broken ground, it is formed in small detachments behind the infantry, through whose intervals it may pa at proper opportunities. The power of readily appreciating the character of ground for military purposes is what is called by foreign writers the military coup d’œil ; and this can only be acquired by a profound knowledge of military tactics of war, joined to much experience in the practice of executing military surveys, and of contemplating the appearance of ground from all po ible points of view.
