Infantry support guns or battalion guns are artillery weapons designed and used to increase firepower of infantry units they are intrinsic to; offering immediate tactical response to the needs of the unit's commanding officer. The designs are typically with short low velocity barrels, and light construction carriages allowing them to be more easily manoeuvred on the battlefield. They are generally used for direct fire missions, as opposed to indirect fire like other artillery units. Their role has generally been replaced by tanks using tank guns, infantry fighting vehicles using autocannons, other combat vehicles, mortars, recoilless rifles, rocket-propelled grenades and shoulder-launched missiles.
The year 1765 in science and technology involved some significant events.
Adolphe Édouard Casimir Joseph Mortier, 1st Duke of Trévise was a French military commander and Marshal of the Empire under Napoleon I, who served during both the French Revolutionary Wars and the Napoleonic Wars. He was one of 18 people killed in 1835 during Giuseppe Marco Fieschi's assassination attempt on King Louis Philippe I.
Lieutenant General Jean-Baptiste Vaquette de Gribeauval was a French artillery officer and engineer who revolutionized the French cannon, creating a new production system that allowed for lighter, more uniform guns without sacrificing range. His Gribeauval system superseded the de Vallière system. These guns proved essential to French military victories during the Napoleonic Wars. Gribeauval is credited as the earliest known advocate for the interchangeability of gun parts. He is thus one of the principal influences on the later development of interchangeable manufacture.
The Gribeauval system was an artillery system introduced by Lieutenant General Jean Baptiste Vaquette de Gribeauval during the 18th century. This system revolutionized French cannons, with a new production system that allowed lighter, more uniform guns without sacrificing range. The Gribeauval system superseded the Vallière system beginning in 1765. The new guns contributed to French military victories during the French Revolutionary Wars and Napoleonic Wars. The system included improvements to cannons, howitzers, and mortars. The Year XI system partly replaced the field guns in 1803 and the Valée system completely superseded the Gribeauval system in 1829.
Jean Maritz (1680–1743), also Johan Maritz, was a Swiss inventor, born in Burgdorf, Canton of Bern, who moved to France, becoming "Commissaire des Fontes" at Strasbourg, and invented the vertical drilling machine, as well as the horizontal drilling machine for cannons in the 18th century. His inventions revolutionized cannon-making, and became a key component of the de Vallière system, and contributed to the development of the later Gribeauval system.
The Valée system was an artillery system developed between 1825 and 1831 by the French artillery officer Sylvain Charles Valée, and officially adopted by the French Army from 1828.
The Canon de 12 Gribeauval or 12-pounder was a French cannon and part of the system developed by Jean Baptiste Vaquette de Gribeauval. There were 1.079 English pounds in the Old French pound, making the weight of shot nearly 13 English pounds. The 12-pounder was the heaviest cannon in the French field artillery; the others were the light Canon de 4 Gribeauval and the medium Canon de 8 Gribeauval. Superseding the previous Vallière system, the Gribeauval system was adopted in 1765 and its guns were first used during the American Revolutionary War. The greatest use of Gribeauval guns came during the French Revolutionary Wars and the Napoleonic Wars. During the latter wars, the 12-pounder was often employed in corps artillery reserves. Because of their physical and psychological effect, Emperor Napoleon increased the number of 12-pounders in his artillery and fondly called the cannons his belles filles. Gribeauval cannons fired canister shot for close-range work and round shot at more distant targets. In 1803 the Year XI system was introduced, but it only partly replaced the Gribeauval system which was not completely replaced until the Valée system was set up in 1829.
The Canon de 8 Gribeauval or 8-pounder was a French cannon and part of the Gribeauval system developed by Jean Baptiste Vaquette de Gribeauval. The Old French pound was 1.07916 English pounds, making the weight of shot about 8.633 English pounds. The 8-pounder was the medium weight cannon of the French field artillery; the others were the light Canon de 4 Gribeauval and the heavy Canon de 12 Gribeauval. Replacing the older Vallière system, the Gribeauval system was introduced in 1765 and the guns were first employed during the American Revolutionary War. The most extensive use of Gribeauval guns was during the French Revolutionary Wars and the Napoleonic Wars. The 8-pounder could be found in divisional reserves, advanced guards or army artillery reserves. Emperor Napoleon began to phase out the 8-pounder by increasing the proportion of 12-pounders in his artillery. The emperor began switching calibers to the handier 6-pounder piece, utilizing captured guns as well as newly designed French cannons. The Year XI system began in 1803, but it only partly replaced the Gribeauval system which was not entirely suppressed until the Valée system was introduced in 1829.
The Obusier de 6 pouces Gribeauval or 6-inch howitzer was a French artillery piece and part of a system established by Jean Baptiste Vaquette de Gribeauval. The Old French inch was 1.066 English inches long so the weapon can accurately be described as a 6.4-inch howitzer.
Jean-Florent de Vallière was a French artillery officer of the 18th century. He was lieutenant-general of the King's Armies. In 1726, de Vallière became Director-General of the Battalions and Schools of the Artillery.
The Canon de 16 Gribeauval was a French cannon and part of the Gribeauval system developed by Jean Baptiste Vaquette de Gribeauval. It was part of the siege artillery.
The Obusier de 15 cm Valée, was a French Artillery 6-inches howitzer belonging to the Valée system of artillery developed between 1825 and 1831 by the French artillery officer Sylvain Charles Valée.
The Canon de 24 Gribeauval was a French 24-pounder cannon and part of the Gribeauval system developed by Jean Baptiste Vaquette de Gribeauval. It was part of the siege artillery.
The Year XI system was a French artillery system developed during the rule of Napoleon. The Year XI system was original in that it brought various improvements to the highly successful Gribeauval system, on which many successes of the Napoleonic Wars relied. It especially consisted in streamlining the existing Gribeauval designs. The main proponent of the new system was General Marmont. It was superseded by the Valée system.
The Canon lourd de 12 Gribeauval was a French cannon and part of the Gribeauval system developed by Jean Baptiste Vaquette de Gribeauval. It was part of the siege artillery.
The Canon lourd de 8 Gribeauval was a French canon and part of the Gribeauval system developed by Jean Baptiste Vaquette de Gribeauval. It was part of the siege artillery.
The Canon de 6 système An XI was a French cannon and part of the Year XI system of artillery. It was part of the field artillery, and complemented the Gribeauval system.
The Monster Mortar was one of the largest mortars ever developed. Also called Leopold or the Liege mortar, the 24 inches (610 mm) caliber mortar was conceived by the French artillery officer Henri-Joseph Paixhans. The mortar was manufactured under the direction of the Belgian Minister of War Baron Louis Evain and cast at the Belgian royal foundry in Liège, Belgium in 1832. It saw action at the Battle of Antwerp in December 1832.
The Canon de 4 Gribeauval or 4-pounder was a French cannon and part of the artillery system developed by Jean Baptiste Vaquette de Gribeauval. The Old French pound was 1.079 English pounds, making the weight of shot about 4.3 English pounds. In the Gribeauval era, the 4-pounder was the lightest weight cannon of the French field artillery; the others were the medium Canon de 8 Gribeauval and the heavy Canon de 12 Gribeauval. The Gribeauval system was introduced in 1765 and the guns were first employed during the American Revolutionary War. The most large-scale use of Gribeauval guns occurred during the French Revolutionary Wars and the Napoleonic Wars. At first a pair of 4-pounders were assigned to each infantry battalion and were often called battalion pieces. Later, Emperor Napoleon took the guns away from the infantry units and began to replace the 4-pounder with the 6-pounder, using captured guns as well as newly cast French cannons. However, as the French infantry declined in quality after 1809, the 4-pounders were reintroduced in order to provide direct support for formations of foot soldiers. All Gribeauval cannons were capable of firing canister shot at close-range and round shot at long-range targets. The Gribeauval system supplanted the older Vallière system, was partly replaced by the Year XI system in 1803 and completely superseded by the Valée system in 1829.
