The Canon-obusier (literally "Shell-gun cannon", "gun-howitzer") was a type of cannon developed by France in the 1850s. The canon-obusier was a smoothbore cannon using either explosive shells, solid shot, or canister, and was therefore a vast improvement over previous cannon firing only solid and canister shot, such as the Gribeauval system.

The very first canon-obusiers were naval shell guns, invented in 1823 by Henri-Joseph Paixhans and introduced in the French Navy in 1842. [1] This invention was related to the origin of the development of the Dahlgren shell gun in the United States in 1849.

The French Army introduced the canon-obusier de 12 in 1853. The US version of this type of canon-obusier, commonly called the "12-pounder Napoleon Model 1857", was one of the most-used cannon in the American Civil War. [2] [3] Over 1,100 of these "Napoleons" were manufactured by the Union, and 600 by the Confederacy. [4]

The canon-obusier de 12 followed rifled cannon of the Treuille de Beaulieu system which had been introduced in 1858. [5]

The term "Canon-obusier" remained in use after World War I to designate various gun howitzers of the French Army.

Dahlgren guns were muzzle-loading naval artillery designed by Rear Admiral John A. Dahlgren USN, mostly used in the period of the American Civil War. Dahlgren's design philosophy evolved from an accidental explosion in 1849 of a 32 lb (14.5 kg) gun being tested for accuracy, killing a gunner. He believed a safer, more powerful naval cannon could be designed using more scientific design criteria. Dahlgren guns were designed with a smooth curved shape, equalizing strain and concentrating more weight of metal in the gun breech where the greatest pressure of expanding propellant gases needed to be met to keep the gun from bursting. Because of their rounded contours, Dahlgren guns were nicknamed "soda bottles", a shape which became their most identifiable characteristic.

<span class="mw-page-title-main">Twelve-pound cannon</span>

The twelve-pound cannon is a cannon that fires twelve-pound projectiles from its barrel, as well as grapeshot, chain shot, shrapnel, and later shells and canister shot. It was first used during the Tudor period and was commonly used during the Napoleonic Wars, 1799–1815. At this time 12-pounders were the largest caliber of long-barreled field pieces, and were used both at long range against fortifications and troop concentrations using round shot and against attacking infantry and cavalry using canister shot. As such the 12-pounder was a favorite weapon of the Grande Armée. Later, redesigned 12-pounders were named after Napoleon III and found heavy use during the American Civil War.

12-pounder gun or 12-pdr, usually denotes a gun which fired a projectile of approximately 12 pounds.

Count Antoine Hector Thésée Treuille de Beaulieu was a French General of the 19th century, who developed the concept of rifled guns in the French Army. He studied the subject of rifling between 1840, particularly in the famous Manufacture d'armes de Châtellerault, and 1852. Following a request by Napoleon III in 1854 to develop such a weapon, the de Beaulieu system was adopted by the French Army. It consisted in cutting six grooves inside the bore of a muzzle-loading cannon, and to use shells equipped with six lugs which would engage the grooves. This development was paralleled by that of the Armstrong gun in Great Britain.

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.

<span class="mw-page-title-main">Canon obusier de 12</span> French field gun of 1853

The Canon obusier de 12, also known as the "Canon de l’Empereur", was a type of canon-obusier developed by France in 1853. Its performance and versatility allowed it to replace all the previous field guns, especially the Canon de 8 and the Canon de 12 as well as the two howitzers of the Valée system.

<span class="mw-page-title-main">Canon de 12 Gribeauval</span> Weapon

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.

<span class="mw-page-title-main">Canon de 8 Gribeauval</span> Weapon

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.

<span class="mw-page-title-main">Obusier de 6 pouces Gribeauval</span> French artillery piece

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.

French weapons in the American Civil War had a key role in the conflict and encompassed most of the sectors of weaponry of the American Civil War (1861–1865), from artillery to firearms, submarines and ironclad warships. The effect of French weapons was especially significant in field artillery and infantry. These weapons were either American productions based on French designs, or sometimes directly imported from France.

<span class="mw-page-title-main">Canon de 4 Gribeauval</span> Weapon

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.

<span class="mw-page-title-main">3-inch ordnance rifle</span> Rifled cannon

The 3-inch ordnance rifle, model 1861 was a wrought iron muzzleloading rifled cannon that was adopted by the United States Army in 1861 and widely used in field artillery units during the American Civil War. It fired a 9.5 lb (4.3 kg) projectile to a distance of 1,830 yd (1,670 m) at an elevation of 5°. The 3-inch rifle was not as effective in firing canister shot as the heavier 12-pounder Napoleon, but it proved to be highly accurate at longer ranges when firing common shell or spherical case shot. There was only one reported case of a 3-inch ordnance rifle bursting in action. This was in stark contrast to the similarly-sized cast iron 10-pounder Parrott rifles which occasionally burst without warning, inflicting injury on the gun crews. The Confederate States of America lacked the technology to manufacture reliable copies of the 3-inch ordnance rifle. However, the Confederate States Army respected the weapons and employed those captured from Federal forces.

<span class="mw-page-title-main">M1841 6-pounder field gun</span> Smoothbore cannon

The M1841 6-pounder field gun was a bronze smoothbore muzzleloading cannon that was adopted by the United States Army in 1841 and used from the Mexican–American War to the American Civil War. It fired a 6.1 lb (2.8 kg) round shot up to a distance of 1,523 yd (1,393 m) at 5° elevation. It could also fire canister shot and spherical case shot (shrapnel). The cannon proved very effective when employed by light artillery units during the Mexican–American War. The cannon was used during the early years of the American Civil War, but it was soon outclassed by newer field guns such as the M1857 12-pounder Napoleon. In the U.S. Army, the 6-pounders were replaced as soon as more modern weapons became available and none were manufactured after 1862. However, the Confederate States Army continued to use the cannon for a longer period because the lesser industrial capacity of the South could not produce new guns as fast as the North.

<span class="mw-page-title-main">M1841 12-pounder howitzer</span> Howitzer

The M1841 12-pounder howitzer was a bronze smoothbore muzzle-loading artillery piece that was adopted by the United States Army in 1841 and employed during the Mexican–American War and the American Civil War. It fired a 8.9 lb (4.0 kg) shell up to a distance of 1,072 yd (980 m) at 5° elevation. It could also fire canister shot and spherical case shot. The howitzer proved effective when employed by light artillery units during the Mexican–American War. The howitzer was used throughout the American Civil War, but it was outclassed by the 12-pounder Napoleon which combined the functions of both field gun and howitzer. In the U.S. Army, the 12-pounder howitzers were replaced as soon as more modern weapons became available. Though none were manufactured after 1862, the weapon was not officially discarded by the U.S. Army until 1868. The Confederate States of America also manufactured and employed the howitzer during the American Civil War.

<span class="mw-page-title-main">10-pounder Parrott rifle</span> Rifled cannon

The 10-pounder Parrott rifle, Model 1861 was a muzzle-loading rifled cannon made of cast iron that was adopted by the United States Army in 1861 and often used in field artillery units during the American Civil War. Like other Parrott rifles, the gun breech was reinforced by a distinctive band made of wrought iron. The 10-pounder Parrott rifle was capable of firing shell, shrapnel shell, canister shot, or solid shot. Midway through the war, the Federal government discontinued the 2.9 in (74 mm) version in favor of a 3.0 in (76 mm) version. Despite the reinforcing band, the guns occasionally burst without warning, which endangered the gun crews. The Confederate States of America manufactured a number of successful copies of the gun.

<span class="mw-page-title-main">20-pounder Parrott rifle</span> Type of rifled cannon

The 20-pounder Parrott rifle, Model 1861 was a cast iron muzzle-loading rifled cannon that was adopted by the United States Army in 1861 and employed in field artillery units during the American Civil War. As with other Parrott rifles, the gun breech was reinforced by a distinctive wrought iron reinforcing band. The gun fired a 20 lb (9.1 kg) projectile to a distance of 1,900 yd (1,737 m) at an elevation of 5°. The 20-pounder Parrott rifle could fire shell, shrapnel shell, canister shot, and more rarely solid shot. In spite of the reinforcing band, the 20-pounder earned a dubious reputation for bursting without warning, killing or injuring gunners. The Confederate States of America also manufactured copies of the gun.

<span class="mw-page-title-main">M1857 12-pounder Napoleon</span> Gun-Howitzer

The M1857 12-pounder Napoleon or Light 12-pounder gun or 12-pounder gun-howitzer was a bronze smoothbore muzzleloading artillery piece that was adopted by the United States Army in 1857 and extensively employed in the American Civil War. The gun was the American-manufactured version of the French canon obusier de 12 which combined the functions of both field gun and howitzer. The weapon proved to be simple to produce, reliable, and robust. It fired a 12.03 lb (5.5 kg) round shot a distance of 1,619 to 1,680 yd at 5° elevation. It could also fire canister shot, common shell, and spherical case shot. The 12-pounder Napoleon outclassed and soon replaced the M1841 6-pounder field gun and the M1841 12-pounder howitzer in the U.S. Army, while replacement of these older weapons was slower in the Confederate States Army. A total of 1,157 were produced for the U.S. Army, all but a few in the period 1861–1863. The Confederate States of America utilized captured U.S. 12-pounder Napoleons and also manufactured about 500 during the war. The weapon was named after Napoleon III of France who helped develop the weapon.
