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 (case shot), 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.

Background

Robert Parker Parrott was an ordnance officer in the US Army who inspected cannons manufactured at the West Point Foundry in Cold Spring, New York. In 1836, president of the company Gouverneur Kemble persuaded Parrott to resign from the Army and join his firm. Several years before the American Civil War, gun founders grappled with the problem of rifling cannons. [1] Bronze smoothbore cannons had windage – or space – between the round shot and the barrel. Windage caused the propellant gases from the gunpowder explosion to leak out, but it also put less stress on the gun barrel. With rifled cannon, the ammunition was designed to expand the shell so that there was no windage between the projectile and the gun barrel. This meant that a smaller gunpowder charge could throw a rifled projectile farther, but it also meant that the gun barrel was put under greater stress. [2] Bronze cannons infrequently burst because the metal was flexible. Cast iron was stronger than bronze, but it was also more rigid. This made cast iron guns more prone to burst at the breech or muzzle. [3]

Bronze was too soft a metal for rifled guns. Cast iron was hard enough to take rifling but it was too brittle. Parrott's solution to this puzzle was a cast iron rifled cannon that had a wrought iron reinforcing band wrapped around the breech. [1] When banded guns were manufactured, gravity acted on the bands as they cooled, making an uneven fit around the gun barrel. Parrott overcame the problem by slowly rotating the gun barrel while it was being cooled. The Parrott rifle was first developed in 1859–1860. [4] Parrott later noted of his invention, "I do not profess to think that they are the best gun in the world, but I think they were the best practical thing that could be got at the time". [5] The U.S. government bought the first ten 10-pounder Parrott rifles on 23 May 1861. [1] The U.S. Ordnance Department trusted Robert Parrott to such a degree that he was allowed to be the inspecting officer until the end of 1862. This was a unique arrangement since Parrott was also the manufacturer. [1]

Manufacture

The West Point Foundry produced about 300 20-pounder Parrott rifles between September 1861 and July 1864. The gun barrels weighted between 1,635 lb (742 kg) and 1,815 lb (823 kg). The rifling consisted of five lands and grooves of right-hand gaining twist (increasing toward the muzzle) and the caliber (bore diameter) was 3.67 in (93 mm). [6] The 20-pounder Parrott had a reinforcing band 16.25 in (41 cm) long and 1.5 in (38 mm) thick. The Register of Inspections recorded numbers 1 through 284. However, there were gaps in the record and surviving guns have been found with numbers in the gaps. Also, there is a gun at Gettysburg National Military Park with registry number 296, so it is likely that the real number of guns produced is at least 296. [7] The cost per gun was approximately $380. [8] A number of the guns were designed for Navy use and had a block and pin that fitted over the cascabel (end knob). Only 15 Federal-made guns are known to have survived to the present day. [6]

The Tredegar Iron Works in the Confederacy produced 45 20-pounder Parrott rifles between August 1862 and December 1864. Like the Federal version, the guns were rifled with five grooves in a right-hand twist. The Confederate pattern differed from the Federal gun by having a reinforcing band 20 in (51 cm) long and 2 in (51 mm) thick. This resulted in the guns averaging 1,866 lb (846 kg) each, which is 51 lb (23 kg) more than the heaviest Federal pieces. The Noble Brothers & Company of Rome, Georgia contracted to manufacture 20-pounder Parrott rifles for the Confederacy, but it is not known if they were produced and none have survived. [9] There are 14 surviving Confederate-made 20-pounder Parrott rifles of which two have markings from the Macon Arsenal and the others were made at Tredegar. The two Macon Arsenal guns have weights averaging 1,657 lb (752 kg). [10]

The 20-pounder Parrott rifle had a bore (caliber) with a diameter of 3.67 in (93 mm) and fired a projectile weighing 20 lb (9.1 kg). Its gun barrel was 84 in (213 cm) long and weighed about 1,750 lb (794 kg). The gunpowder charge weighed 2.0 lb (0.9 kg) and fired the projectile with a muzzle velocity of 1,250 ft/s (381 m/s) to a distance of 1,900 yd (1,737 m) at 5° elevation. [11] A smoothbore cannon's projectile usually retained only one-third of its muzzle velocity at 1,500 yd (1,372 m) and its round shot could be seen in the air. At the same distance, a rifled projectile often retained two-thirds of its muzzle velocity and was not visible while in flight. A rifled projectile only became visible if it started to tumble out of control. Tumbling occurred when the shell failed to take the grooves inside the gun barrel or when the spin wore off in flight. [12]

Rifling allowed elongated/heavier rounds to be fired. For example, smoothbore cannons of the same 3.67 caliber as the 20-pounder Parrott fired only 6 pound round shot. For example the M1841 6-pounder field gun. [13]

The 20-pounder Parrott rifle was mounted on the 1,175 lb (533 kg) carriage for the M1841 12-pounder field gun. [14] The 20-pounder Parrott rifle fired case shot (shrapnel), shell, and canister shot. The use of bolts (solid shot) was rare and it was usually not provided in the ammunition chests. Firing a shell without a fuse would achieve the same result as firing a solid shot from a rifled gun. [15] Parrott ammunition was designed to be used. The Parrott rifles could also fire Hotchkiss ammunition, but gunners were not allowed to use Schenkl ammunition. [16] One flaw in Parrott ammunition was the position of the sabot was at the shell's base. This meant that the final impulse on the projectile as it left the gun was on its base, possibly causing the shell to wobble in flight. [17]

When firing Canister shot rifled guns were not as effective as canister fired from a 12-pounder Napoleon or a M1841 12-pounder howitzer. First, the rifled gun's 3.67-inch bore was narrower than the 12-pounder's 4.62 in (117 mm) bore and thus could fire fewer canister balls. Second, the gun's rifling caused the canister to be thrown in an irregular pattern. Union General Henry Jackson Hunt asserted that rifled guns had a canister range only half the 400 yd (366 m) effective range of canister fired from the 12-pounder Napoleon. [18]

Early in the war, many Union batteries were organized with six guns of identical type. [19] However, as will be noted, batteries armed with 20-pounder Parrott rifles often had four guns. [20] Each gun required two 6-horse teams. The first team pulled the gun and its limber and the second team pulled the caisson (ammunition wagon). [21] Each caisson carried two ammunition chests and the limber carried one additional ammunition chest. [22] In addition to its guns, limbers, and caissons, each battery had two additional vehicles, a supply wagon and a portable forge. [23] The 20-pounder Parrott rifle's great weight made it difficult for a 6-horse team to pull. The guns were among the heaviest pieces that could be classified as field artillery, so few were taken along with the field armies. [24] The 10-pounder Parrott rifle was more frequently utilized. [25] Under normal conditions, infantry could be expected to march 15 mi (24.1 km) in six hours, while it would take an artillery battery 10 hours to march 16 mi (25.7 km). [26]

At the Battle of Antietam on 17 September 1862, the Federal Army of the Potomac employed 22 20-pounder Parrott rifles while the Confederate Army of Northern Virginia had none. [27] The 5th New York Independent Light Artillery (Taft's) and 1st New York Light Artillery Battalion, Batteries A (Wever's), B (von Kleiser's), and C (Langner's) were all 4-gun 20-pounder Parrott batteries belonging to the V Corps. [28] Simmonds' Battery Kentucky Light Artillery had two 20-pounder Parrott rifles, three 10-pounder Parrott rifles, and one iron 12-pounder howitzer. [29] Simmonds' Battery and the 4-gun 20-pounder Parrott armed 2nd U.S. Artillery, Battery E (Benjamin's) served in the IX Corps. [30] During the Battle of Fredericksburg on 13 December 1862, the 5th New York Battery and Batteries A, B, and C of the New York Battalion served in the Artillery Reserve. [31] The Artillery Reserve was posted on the east bank of the Rappahannock River on Stafford Heights, opposite the town of Fredericksburg, Virginia. [32]

Before the Second Battle of Corinth on 3–4 October 1862, William Rosecrans built several lunettes to defend the west side of Corinth, Mississippi. Battery Phillips was 200 yd (183 m) north of Corona Female College, Battery Williams was 400 yd (366 m) northeast of Phillips, and Battery Robinett was 200 yd (183 m) north of Williams and 675 yd (617 m) west of Corinth. Battery Williams contained 30-pounder Parrott rifles while Battery Robinett was armed with three 20-pounder Parrott rifles and manned by Company C of the 1st U.S. Infantry Regiment. [33] On the first day, Captain Henry Richardson's Battery D, 1st Missouri Light Artillery helped repel two Confederate attacks but lost one gun. [34] On the second day, the Confederate division led by Martin E. Green routed the division of Thomas Alfred Davies in the Union right-center, but not before the Union guns in Battery Powell inflicted serious casualties. Guarding the north side of Corinth, Battery Powell was defended by three 20-pounder Parrott rifles of Richardson's battery and two M1841 24-pounder howitzers. These guns were overrun. [35] However, the tide turned and Federal troops recaptured the position, re-manned the guns, and fired on the retreating Confederates. [36] In the center, Dabney H. Maury's Confederate division launched an assault on David S. Stanley's Federal division. Stanley's position was buttressed by Battery Robinett which became the focus of gallant but unsuccessful Confederate attacks. Losses on both sides were heavy. [37]

Union General Quincy Adams Gillmore believed that Parrott rifles were as good as the best artillery despite their "unequal endurance". He wrote that the Parrotts were easy for gun crews to operate. Nevertheless, the 20-pounder Parrott rifles had many critics. Confederate General J. Johnston Pettigrew complained that a battery of four 20-pounder Parrotts proved to be worthless. He wrote that half their shells exploded almost as soon as they left the gun and many of the others wobbled in flight. Finally, one of the guns burst, killing one gunner and injuring two others. Confederate Major John Haskell wanted the 20-pounder Parrotts taken away from the Macon Light Artillery to spare its men possible injury. Union General Hunt protested that the 20-pounder Parrotts were "very unsatisfactory" [38] because the shells were unreliable and dangerous to Federal troops. He noted that two of the guns burst at Antietam and one at Fredericksburg. Hunt tried to suppress the use of the 20-pounders in the Army of the Potomac. One of the guns of Taft's Battery (5th New York) burst at Gettysburg. [39] Parrott rifles were not employed again after the Civil War. [1]

Rodman gun

The Rodman gun is any of a series of American Civil War–era columbiads designed by Union artilleryman Thomas Jackson Rodman (1815–1871). The guns were designed to fire both shot and shell. These heavy guns were intended to be mounted in seacoast fortifications. They were built in 8-inch, 10-inch, 13-inch, 15-inch, and 20-inch bore. Other than size, the guns were all nearly identical in design, with a curving bottle shape, large flat cascabels with ratchets or sockets for the elevating mechanism. Rodman guns were true guns that did not have a howitzer-like powder chamber, as did many earlier columbiads. Rodman guns differed from all previous artillery because they were hollow cast, a new technology that Rodman developed that resulted in cast-iron guns that were much stronger than their predecessors.

Dahlgren gun American naval gun of the 19th Century

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.

Brooke rifle

The Brooke rifle was a type of rifled, muzzle-loading naval and coast defense gun designed by John Mercer Brooke, an officer in the Confederate States Navy. They were produced by plants in Richmond, Virginia, and Selma, Alabama, between 1861 and 1865 during the American Civil War. They served afloat on Confederate ships and ashore in coast defense batteries operated by the Confederate States Army.

Field artillery 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.

Siege artillery in the American Civil War

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.

Wiard rifle

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.

James rifle Type of artillery gun

James rifle is a generic term to describe any artillery gun rifled to the James pattern for use in the American Civil War, as used in some period documentation. Charles T. James developed a rifled projectile and rifling system. Modern authorities such as Warren Ripley and James Hazlett have suggested that the term "James rifle" only properly applies to 3.8 in (97 mm) bore field artillery pieces rifled to fire James' projectiles. They contend that the term does not apply to smoothbores that were later rifled to take the James projectiles in 3.67 in (93 mm) caliber or other calibers, and that those should instead be referred to as "Rifled 6 pounder", etc.

68-pounder gun Naval gunCoast Defence gun

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.

3-inch ordnance rifle Rifled cannon

The 3-inch ordnance rifle, model 1861 was a wrought iron muzzle-loading 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 shell or shrapnel. 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 successful copies of the 3-inch ordnance rifle. However, the Confederate States Army respected the weapons and employed those captured from Federal forces.

M1841 6-pounder field gun Smoothbore cannon

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.

M1841 12-pounder howitzer 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 from the Mexican–American War to 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 US 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 US Army until 1868. The Confederate States of America also manufactured and employed the howitzer during the American Civil War. The Confederate armies used the outmoded howitzer for a longer period.

10-pounder Parrott rifle Rifled cannon

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.

Independent Battery F, Pennsylvania Light Artillery Military unit

Independent Battery F, Pennsylvania Light Artillery, also known as the "Pittsburg Battery", was an artillery battery that served in the Union Army during the American Civil War. Organized in December 1861, the unit first served in the Shenandoah Valley. Battery F fought at Hancock, Winchester, Sulphur Springs, Second Bull Run, Chantilly, and Antietam in 1862. The following year the unit fought at Chancellorsville, Gettysburg, the Bristoe Campaign, and Mine Run. In 1864–1865, Battery F fought at Morton's Ford and served in the garrisons of Washington, D.C. and Harper's Ferry, West Virginia before being mustered out in June 1865. One enlisted man from the battery won the Medal of Honor for heroic action at Gettysburg.

14-pounder James rifle Rifled cannon

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.

Bridges Battery Illinois Light Artillery Military unit

Bridges' Battery Illinois Light Artillery was an artillery battery from Illinois that served in the Union Army during the American Civil War. Organized on 17 June 1861 as Company G, 19th Illinois Infantry Regiment, it was detached as an independent artillery battery on 14 January 1863. The battery fought in the Tullahoma campaign, at the battles of Chickamauga and Missionary Ridge, and in the Knoxville campaign in 1863. Bridges' Battery participated in the Atlanta campaign in 1864, fighting at Rocky Face Ridge, Resaca, Adairsville, Pickett's Mill, Kennesaw Mountain, Peachtree Creek, Atlanta, and Jonesboro. The unit fought at Franklin and Nashville shortly before it was renamed Battery "B", 1st Illinois Light Artillery Regiment on 21 December 1864. It spent the rest of the war with the Nashville garrison and was mustered out in July 1865.

Battery E, 1st Missouri Light Artillery Regiment Military unit

Battery E, 1st Missouri Light Artillery Regiment was an artillery battery unit from Missouri that served in the Union Army during the American Civil War. The 1st Missouri Light Artillery Regiment formed on 1 September 1861. The battery participated in Frémont's expedition to Springfield in October 1861. This was followed by actions at Prairie Grove and Van Buren in December 1862. The following year, the battery fought at Cape Girardeau, Chalk Bluff, Vicksburg, the Expedition to Morganza, Brownsville, and Fort Esperanza. After performing garrison duty at Brownsville, Texas, the unit was mustered out in June 1864. For a few months at the end of 1864, a Pennsylvania battery took the name of this unit.

M1841 24-pounder howitzer Howitzer

The M1841 24-pounder howitzer was a bronze smoothbore muzzle-loading artillery piece adopted by the United States Army in 1841 and employed from the Mexican–American War through the American Civil War. It fired a 18.4 lb (8.3 kg) shell to a distance of 1,322 yd (1,209 m) at 5° elevation. It could also fire canister shot and spherical case shot. The howitzer was designed to be employed in a mixed battery with 12-pounder field guns. By the time of the American Civil War, the 24-pounder howitzer was superseded by the 12-pounder Napoleon, which combined the functions of both field gun and howitzer. The 24-pounder howitzer's use as field artillery was limited during the conflict and production of the weapon in the North ended in 1863. The Confederate States of America manufactured a few 24-pounder howitzers and imported others from the Austrian Empire.
