COUVRE-FACE, Fr. a term used by some engineers, and among others by Cohorn, to express the counter-guard: others, particularly Montalembert, convey by couvre face géneral a second line of complete investment.
To COVER, in the mechanical disposition of a battallion, company or squad, only means that a man is to stand in such a position in files, as that when he looks exactly forward to the neck of the man who leads him, he cannot see the second man from him. Nothing but great attention at the drill can bring men to cover so truly as never to destroy the perpendicular direction of any leading body. The least deviation in the men who cover upon either flank of a leading column or division, will throw all that follow out of the true line.
To Cover ground, is to occupy a certain proportion of ground individually, or collectively. A foot soldier upon an average covers 22 inches of ground when he stands in the ranks. The dimensions are taken from his shoulder points.
A file on horseback covers or occupies in the ranks about 2 feet 8 inches. Thus three file, 8 feet; twelve file will occupy about 32 feet or 10 yards and 2 feet; thirteen file, 34 feet 8 inches, or 11 yards, 1 foot 8 inches; fourteen file, 37 feet 4 inches, or 12 yards 1 foot 4 inches, and so on.
One horse’s length from nose to croup, on an average, 8 feet and about 2 inches, or 2 yards 2 feet 2 inches. This consequently will be the space which about three files occupy in front.
Cavalry and infantry officers cannot pay too much attention to the calculation of distances by an accurate knowlege of which, ground will be properly covered, and any proportion of men, on horseback or on foot, be drawn up so as to answer the intentions of an able general. The best way that an officer can form his eye, is to exercise it to the measurement of ground by the regular pace of two feet, used in the military drawing; by this he can calculate his interval exactly, when he once knows how many feet his division occupies; for it is only halving the number of feet, and the number, so produced, is his distance in paces of two feet each. This instruction has been given to cavalry officers, by a very able Tactician.
Cover, a term in war to express security or protection: thus, to land under cover of the guns, is to advance offensively against an enemy who dares not approach on account of the fire from ships, boats or batteries. It likewise signifies whatever renders any movement imperceptible: as, under cover of the night, under cover of a wood, &c. The gallery or corridor in fortification is however, particularly distinguished by the term Chemin Couvert, covert way, because the glacis of the parade is its parapet.
