Part 97

CONVOYS. A waggon with four horses occupies about sixteen paces; a mile will therefore hold about 117 waggons: but allowing a short distance between each waggon in travelling, a mile may be said to contain 100 waggons. Waggons in convoy may travel from one to two miles per hour, according to the roads and other circumstances. A great object in convoys is to preserve the horses as much as possible from fatigue. For this purpose, if the convoy amounts to many hundred waggons, they must be divided into divisions of not more than 500 each. Should it consist of thousands, it will be adviseable to divide them into grand divisions, and then again into subdivisions of 500 each: by this means, and the time of departure being calculated by the following rules, each division may remain at rest, till just before its time of movement; and which will prevent the necessity of the latter part of a large convoy being harrassed for a considerable time before its turn to move.

Rule 1. To find the time in which any number of waggons may be driven off: Divide the number of waggons by 100, and multiply by the time of travelling one mile.

Rule 2. To find the time in which any number of waggons will drive over any number of miles: To the time they take in driving off, add the time any one of the waggons takes to travel the distance.

The different divisions of the convoy should be numbered, and obliged each day to change the order of their marching.

Whenever the progress of a train of waggons is arrested by the breaking down of any one of them, or other delay, all the waggons in the rear of the stoppage, should immediately drive up into the first open space, to as great a number as the open space will hold; this keeps the convoy together and better under the care of the escort.

The escort for a convoy should be divided into front, centre, and rear guards; beside the divisions for the flanks, which should never be beyond musquet shot, or at most 400 yards from each other. The whole escort should never be so separated that they could not be collected in an hour. Under proper precautions against an enemy, a convoy of any size cannot travel more than ten or fifteen miles per day.

To CO-OPERATE, to put a well digested plan into execution, so that forces, however divided, may act upon one principle and towards one end.

COOK, each troop or company has cooks, who are excused from other duties.

COPPER. No other metal is allowed to the magazines, or barrels of gunpowder.

COQUILLES à boulet, Fr. shells or moulds. They are made either of brass or iron; two are required for the casting of a cannon ball; but they never close so effectually as to prevent the liquid metal, which has been poured in, from running somewhat out of the part where they join. This excrescence is called the beard, which is broken off to render the ball completely round.

CORBEILLES, Fr. Large baskets, which being filled with earth, and placed one by another along the parapet, serve to cover the besieged from the shot of the besieging enemy. They are made wider at top than at the bottom, in order to afford loop-holes, through which the men may fire upon the besiegers. Their usual dimensions are one foot and a half high, as much in breadth at the top, and eight or ten inches at the bottom. See GABION.

CORDE, Fr. Cord, in geometry and fortification, means a straight line which cuts the circumference into two parts, without running through the centre.

CORDEAU, Fr. a cord which is used in measuring ground. It is divided into toises, feet, and inches, for the purpose of ascertaining with precision, the opening of angles and the extent of lines. In wet weather a small chain made of wire is substituted to prevent mistakes that would necessarily occur, from the cord becoming shorter or longer, according to the influence of the weather. The technical terms among French Engineers, are Manier le cordeau, Pendre le cordeau, Travailler au cordeau.

CORDON, in fortification, is a row of stones made round on the outside, and placed between the termination of the slope of the wall, and the parapet which stands perpendicular, in such a manner, that this difference may not be offensive to the eye; whence those cordons serve only as ornaments in walled fortifications.

The CORDON of the revetement of the rampart is often on a level with the terre pleine of the rampart. It has been observed in a late French military publication, that it might be more advantageously placed some feet lower; especially when there is a wall attached to the parapet, to shield the rounds from the enemy’s fire.

CORDON, in military history, is a chain of posts, or an imaginary line of separation between two armies, either in the field or in winter quarters.

CORIDOR, the covert way which is formed between the fossé and the pallisade on the counterscarp. See COVERT-way. This word is becoming obsolete as a military term, and is chiefly confined to domestic buildings.

CORNAGE, an ancient tenure, which obliged the land-holder to give notice of an invasion by blowing a horn.

CORNE, ou OUVRAGE a CORNE, Fr. See HORNED WORK.

CORNET, in the military history of the ancients, an instrument much in the nature of a trumpet: when the cornet only sounded, the ensigns were to march alone without the soldiers; whereas, when the trumpet only sounded, the soldiers were to move forward without the ensigns. A troop of horse was so called.

CORNET, in the military history of the moderns, the junior commissioned officer in a troop of horse or dragoons, subordinate to the captain and lieutenants, equivalent to the ensign amongst the foot. His duty is to carry the standard, near the centre of the front rank of the squadron.

CORNETTE-BLANCHE, Fr. an ornament which in ancient times, served to distinguish French officers who were high in command. It was worn by them on the top of their helmets. It likewise meant a royal standard, and was substituted in the room of the Pennon Roïal. The cornette-blanche was only unfurled when the king joined the army; and the persons who served under it were princes, noblemen, marshals of France, and old captains, who received orders from the king direct.

CORNETTE, Fr. See CORNET.

The CORNETTES or Cornets, of the colonel general of cavalry, in the old French service, as well as those attached to the quarter-master general and commissary general, ranked as lieutenants, and the cornettes of la colonelle général des dragons ranked as youngest lieutenants, and commanded all other cornets.

CORNETTE, Fr. was likewise the term used to signify the standard peculiarly appropriated to the light cavalry. Hence cornettes and troops were synonimous terms to express the number of light-horse attached to an army. The standard so called was made of taffeta or glazed silk, one foot and a half square, upon which the arms, motto, and cypher of the officer who commanded the cavalry were engraved. A sort of scarf or long piece of white silk, (the old French colors) was tied to the cornette whenever the cavalry went into action, in order to render the standard conspicuous, that the men might rally round it.

CORNISH ring, in gunnery, the next ring from the muzzle backwards. See CANNON.

CORPORAL, a rank and file man with superior pay to that of common soldiers, and with nominal rank under a serjeant. He has charge of one of the squads of the company, places and relieves centinels, and keeps good order in the guard. He receives the word of the inferior rounds that pass by his guard. Every company should have a corporal for every ten men.

Lance-CORPORAL, one who acts as corporal, receiving pay as a private.
