Gribeauval’s System

—In 1765, Gen. Gribeauval founded a new system, by separating the field from the siege artillery. He diminished the charge of field-guns from a half to a third the weight of the shot, but as he diminished the windage of the projectile at the same time, he was enabled to shorten them and render them lighter, without sensibly diminishing their range. Field artillery then consisted of 12-, 8-, and 4-pounder guns, to which was added a 6-inch howitzer, still retaining a small charge, but larger in proportion to that before used. For draught, the horses were disposed in double files, which was much more favorable to rapid gaits. Iron axle-trees, higher limbers, and traveling trunnion-holes rendered the draught easier. The adoption of cartridges, elevating screws, and tangent scales, increased the rapidity and regularity of the fire. Stronger carriages were made for the lighter guns, and the different parts of all were made with more care, and strengthened with ironwork. Uniformity was established in all the new constructions, by compelling all the arsenals to make every part of the carriages, wagons, and limbers according to certain fixed dimensions. By this exact correspondence of all the parts of a carriage, spare parts could be carried into the field ready made, to refit. Thus an equipment was obtained which could be easily repaired, and could be moved with a facility hitherto unknown. In order to reduce the number of spare articles nece ary for repairs, Gribeauval gave, as far as practicable, the same dimensions to those things which were of the same nature. The excellence of this system was tested in the wars of the French republic and empire, in which it played an important part. In 1827, the system of Gribeauval was changed by introducing the 24- and 32-pounder howitzers, lengthened to correspond with the 8- and 12-pounder guns, and abolishing the 4-pounder gun and 6-inch howitzer. Afterwards some important improvements were made in the carriages, chiefly copied from the English system; the number for all field-cannon was reduced to two, the wheels of the carriage and limber were made of the same size; the weight of the limber was reduced, and an ammunition-chest placed on it; the method of connecting the carriage and limber was simplified, and the operations of limbering and unlimbering greatly facilitated; and the two flasks which formed the trail were replaced by a single piece called the stock , which arrangement allowed the new pieces to turn in a smaller space than that required by the old ones.
