The Parrott rifle was a type of muzzle-loading rifled artillery weapon used extensively in the American Civil War.
Field artillery in the American Civil War refers to the artillery weapons, equipment, and practices used by the Artillery branch to support the infantry and cavalry forces in the field. It does not include siege artillery, use of artillery in fixed fortifications, or coastal or naval artillery. Nor does it include smaller, specialized artillery classified as small arms.
The columbiad was a large-caliber, smoothbore, muzzle-loading cannon able to fire heavy projectiles at both high and low trajectories. This feature enabled the columbiad to fire solid shot or shell to long ranges, making it an excellent seacoast defense weapon for its day. Invented by Colonel George Bomford, United States Army, in 1811, columbiads were used in United States seacoast defense from the War of 1812 until the early years of the 20th century. Very few columbiads were used outside of the U.S. and Confederate Armies; nevertheless, the columbiad is considered by some as the inspiration for the later shell-only cannons developed by Frenchman Henri-Joseph Paixhans some 30 years later.
Polygonal rifling is a type of gun barrel rifling where the traditional sharp-edged "lands and grooves" are replaced by less pronounced "hills and valleys", so the barrel bore has a polygonal cross-sectional profile.
The Whitworth rifle was an English-made percussion rifle used in the latter half of the 19th century. A single-shot muzzleloader with excellent long-range accuracy for its era, especially when used with a telescopic sight, the Whitworth rifle was widely regarded as the world's first sniper rifle.
Siege artillery is heavy artillery primarily used in military attacks on fortified positions. At the time of the American Civil War, the U.S. Army classified its artillery into three types, depending on the gun's weight and intended use. Field artillery were light pieces that often traveled with the armies. Siege and garrison artillery were heavy pieces that could be used either in attacking or defending fortified places. Seacoast artillery were the heaviest pieces and were intended to be used in permanent fortifications along the seaboard. They were primarily designed to fire on attacking warships. The distinctions are somewhat arbitrary, as field, siege and garrison, and seacoast artillery were all used in various attacks and defenses of fortifications. This article will focus on the use of heavy artillery in the attack of fortified places during the American Civil War.
During the American Civil War, an assortment of small arms found their way onto the battlefield. Though the muzzleloader percussion cap rifled musket was the most numerous weapon, being standard issue for the Union and Confederate armies, many other firearms, ranging from the single-shot breech-loading Sharps and Burnside rifles to the Spencer and the Henry rifles - two of the world's first repeating rifles - were issued by the hundreds of thousands, mostly by the Union. The Civil War brought many advances in firearms technology, most notably the widespread use of rifled barrels.
The Wiard rifle refers to several weapons invented by Norman Wiard, most commonly a semi-steel light artillery piece in six-pounder and twelve-pounder calibers. About 60 were manufactured between 1861 and 1862 during the American Civil War, at O'Donnell's Foundry, New York City: "although apparently excellent weapons, [they] do not seem to have been very popular". Wiard also designed a rifled steel version of the Dahlgren boat howitzer, among other gun types. Further, Wiard unsuccessfully attempted to develop a 15 in (381 mm) rifled gun for the US Navy and proposed a 20 in (510 mm) gun. In 1881 he unsuccessfully proposed various "combined rifle and smoothbore" weapon conversions of Rodman guns and Parrott rifles.
A Blakely rifle is one of a series of rifled muzzle-loading cannon designed by British army officer Captain Theophilus Alexander Blakely. They were widely sold outside of the British army, and were best known for their use by the Confederate States of America during the American Civil War.
The 68-pounder cannon was an artillery piece designed and used by the British Armed Forces in the mid-19th century. The cannon was a smoothbore muzzle-loading gun manufactured in several weights, the most common being 95 long cwt (4,800 kg), and fired projectiles of 68 lb (31 kg). Colonel William Dundas designed the 112 cwt version in 1841 and it was cast the following year. The most common variant, weighing 95 cwt, dates from 1846. It entered service with the Royal Artillery and the Royal Navy and saw active service with both arms during the Crimean War. Over 2,000 were made and it gained a reputation as the finest smoothbore cannon ever made.
The 70-pounder Whitworth naval gun was designed by Joseph Whitworth during the 1860s. It was a rifled muzzle loader and used his hexagonal, rifled-bore design.
Sylvanus Sawyer was a United States inventor.
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.
The M1841 6-pounder field gun was a bronze smoothbore muzzle-loading 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. 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 12-pounder Napoleon. In the US 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 newer guns as fast as the North.
The 10-pounder Parrott rifle, Model 1861 was a cast iron muzzle-loading rifled cannon 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 wrought iron reinforcing band. The gun fired a 9.5 lb (4.3 kg) projectile to a distance of 1,850 yd (1,692 m) at an elevation of 5°. 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, inflicting injury on the gun crews. The Confederate States of America manufactured a number of successful copies of the gun.
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.
The 14-pounder James rifle or James rifled 6-pounder or 3.8-inch James rifle was a bronze muzzle-loading rifled cannon that was employed by the United States Army and the Confederate States Army during the American Civil War. It fired a 14 lb (6.4 kg) solid shot up to a distance of 1,530 yd (1,400 m) at 5° elevation. It could also fire canister shot and common shell. Shortly before the war broke out, the U.S. Army adopted a plan to convert M1841 6-pounder field guns from smoothbore to rifled artillery. Rifling the existing 6-pounders would both improve the gun's accuracy and increase the weight of the shell. There were two major types produced, both were bronze with a bore (caliber) of 3.8 in (97 mm) that would accommodate ammunition designed by Charles Tillinghast James. The first type looked exactly like an M1841 6-pounder field gun. The second type had a longer tube with a smooth exterior profile similar to a 3-inch Ordnance rifle. At first the rifles were quite accurate. However, it was discovered that the bronze rifling quickly wore out and accuracy declined. None of the rifles were manufactured after 1862, and many were withdrawn from service, though some artillery units employed the guns until the end of the war.
The 3-pounder Whitworth rifle was a small caliber field gun deployed during the mid-19th century. Designed by Joseph Whitworth, the gun was most notably used during the American Civil War.
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.
