Blakely rifle

Last updated

Blakely rifle or Blakely gun is the name of a series of rifled muzzle-loading cannon designed by British army officer Captain Theophilus Alexander Blakely in the 1850s and 1860s. [1] [2] Blakely was a pioneer in the banding and rifling of cannon but the British army declined to use Blakely's design. [3] The guns were mostly sold to Russia and the Confederacy during the American Civil War. [1] [4] Blakely rifles were imported by the Confederacy in larger numbers than other Imported English cannon. [5] The State of Massachusetts bought eight 9 in (23 cm) and four 11 in (28 cm) models. [6] [7] [fn 1]

Blakely rifles had innovative design features using two layer construction and layers of rings which allowed rifling of larger cannons. Blakely's manufacturing innovations allowed larger guns of lighter weight and greater resistance to explosion. The Confederacy used the Blakely rifles in seacoast fortifications, fortifications at Vicksburg, as naval guns and, in the smaller sizes, as artillery in land battles.

Development and production

The Blakely rifled artillery gun was designed with a cast-iron core and included wrought-iron or steel banding to reinforce the breech. [1] [fn 2] Blakely himself noted that the cannon was to be built up tube after tube, compressing the inner tubes and extending the outer tubes by a certain calculation. This was to be done to prevent the inside breaking before sufficient strain was sent to the outside as would be the case with any thick tubes made in one piece. [8] Blakely wrote that, "paradoxically," by using this method of two layer construction, a thick tube would be strengthened by diminishing its thickness and would weigh half as much. [9] Blakely wrote that he had shown that no rifled cannon of considerable size had succeeded when made in one mass. [10] [fn 3] [11]

Blakely was a pioneer in this two tube, or two layer, design. [12] Nonetheless, the British government rejected his designs. [1] The contemporaneous Armstrong guns of Sir William George Armstrong were of similar design, but unlike Blakely, Armstrong had his own foundry at the time. [4] [12] Because Blakely believed that Armstrong had infringed his patents, he stopped offering his designs to the British military when Armstrong became superintendent of the Royal Arsenal at Woolwich. [1]

Blakely contracted with companies including Fawcett, Preston, & Company of Liverpool, Vavasseur of London, George Forrester and Company of Liverpool, Low Moor Iron Company, and the Blakeley Ordnance Company of London (established 1863) for the manufacture of his guns. [13] [fn 4] The cannon foundries produced about 400 guns to Blakely's design. [1] Most were made of iron. [1]

Types, variations

Because Blakely continued to experiment with designs, he produced five to as many as ten different designs, which were manufactured, some with variants. [14] The Blakely rifled guns fired ammunition weighing between 10 lb (4.5 kg) and 470 lb (210 kg). [12] At least nine varieties of 3.5-inch (12-pounder) rifles alone were produced. [14] Rifling types included flat-sided bores or bores with grooves cut in them into which flanges on the shells would fit. [15]

The foundries that manufactured Blakely rifles produced them in 2.5-inch (6-pounder), 2.9-inch, 3.5-inch (12-pounder), 3.75-inch (16-pounder), 4-inch (18-pounder), 4.5-inch (20-pounder), 6.4-inch (100-pounder), 7-inch (120-pounder), 7.5-inch (150-pounder), 8-inch (200-pounder), 9-inch (250-pounder), 11-inch, and 12.75-inch (450-pounder shells or 650-pounder solid shot) bores. [16] All of the caliber rifles did not come to the United States. [17]

Confederate use

Confederate forces used various sizes of Blakely rifles in several ways during the American Civil War.

First use against Fort Sumter

Blakely was more successful in selling cannons to the Confederacy than to the British military or the Union. One of the first guns sold was a 12-pounder Blakely delivered to the Confederates for use against Fort Sumter at the beginning of the American Civil War. [18] [fn 5] That gun was the first rifled cannon fired in the war. [12] The cannon was bought by Charles K. Prioleau in London and sent to Charleston before the surrender of Fort Sumter. [12] The gun was used from Morris Island where it accurately sent projectiles against Fort Sumter, 1,250 yards (1,193 meters) away. [3] [12] It was likely the gun which fired a shot scattering debris from the stone cheek of the casemate embrasure, wounding four Union soldiers. [3]

In other fortifications

On January 3, 1862, Union gunboats shelled Confederate batteries blockading traffic on the Potomac River in the inconclusive Battle of Cockpit Point also known as the Battle of Shipping Point, in Prince William County, Virginia. The Confederates retained the batteries. On March 9, 1862, Union gunboats again approached the Confederate defenses and discovered them abandoned. They captured two guns rifled in the Blakely method that ended up in the Washington Navy Yard. Historian Warren Ripley wrote that he did not think these are 6.3 in (16 cm) and 6.97 in (17.7 cm) Blakelys, but British 32-pounder and 42-pounder smoothbores reworked in the Blakely rifling fashion. [19]

Two Blakely "siege" rifles were used in the Confederate defense of Fort Pulaski in 1862. The Confederate commander of Fort Pulaski near the coast outside of Savannah, Georgia during the Siege of Fort Pulaski, Colonel Charles H. Olmstead, used two 4.5 in (11 cm) Blakely rifles in his ultimately unsuccessful defense which ended with the fort's surrender on April 11, 1862 after a 112-day siege. [20] [21] [22] These rifles were taken to West Point as old trophies numbers 152 and 153 but returned to Fort Pulaski National Monument in the 1930s. [22] [23] [24]

"The Widow Blakely" was a 7.5 in (19 cm) rifle that the Confederates used during their 1863 defense of Vicksburg, Mississippi. [14] [25] On May 22, 1863, a shell exploded in the gun's barrel while the Widow Blakely was firing at a Union gunboat. [26] The explosion only took off part of the end of the muzzle. [26] The Confederates cut away part of the barrel and continued to use the rifle as a mortar until Vicksburg fell to the Union Army under the command of Major General Ulysses S. Grant. [27] [fn 6] A gun at West Point which was misidentified as Whistling Dick was returned to the Vicksburg National Battlefield Park when it was identified by historian Ed Bearss as "Widow Blakely." [28]

Two 12.75 in (32.4 cm) Blakelys, the largest guns in the Confederate arsenal, were mounted in 1863 at Charleston, South Carolina. [12] These were delivered, along with shot, to Wilmington, North Carolina in August 1863 from Liverpool by the blockade runner Gibraltar. [29] These were ordered to the defense of Charleston, South Carolina harbor by Confederate General P. G. T. Beauregard and Confederate Secretary of War James A. Seddon. [29] The rifles had 7 in (18 cm) inside diameter by 30 in (76 cm) long bronze air chamber behind the seat of its charge. [30] General Roswell S. Ripley improperly loaded the chamber of one of the guns with powder to reduce the size of cartridge bags. [31] This cracked the chamber and caused other damage on the first fire and it had to be replaced. [31] The rifle had a 12.75 in (32.4 cm) flanged shot and shell with four grooves and a right-hand twist for rifling. [31] The rifles were never fired against Union forces or ships. [32] They were loaded with excessive charges and blown up when Charleston was evacuated on February 18, 1865. [32] Pieces of the rifles survive at West Point and Charleston, South Carolina. [33]

Principal characteristics of Blakely rifled 12.75 in (32.4 cm) seacoast guns were: Total length of gun: 194 in (490 cm); bore: 12.75 in (32.4 cm); diameter of air chamber: 6.5 in (17 cm); length of bore to bronze chamber: 151.5 in (385 cm); total length of bore to bottom of chamber: 184 in (470 cm); maximum diameter of cast iron: 44 in (110 cm); diameter of cast iron muzzle: 24 in (61 cm); diameter over steel hoop: 51 in (130 cm); weight: 27 tons. [34]

An 8.12 in (20.6 cm) rifled British 68-pounder cannon of 95 hundredweight was captured by Union Army forces at Fort Morgan, Alabama on August 23, 1864. The cannon was originally a smoothbore manufactured by Low Moor Iron Company in 1862. It was banded and rifled with three grooves of right-hand twists in the manner of a Blakely. [29] Olmstead describes the piece as "Identified As A 'Blakely'", casting doubt as to its identity and noting that it is covered in black enamel, obscuring any markings. [29] This cannon is in the Washington Navy Yard. [35] The Official Records of the Union and Confederate Armies list two 8-inch Blakelys as in the Confederate defenses at Fort Morgan. [35]

Four Blakely 9 in (23 cm) seacoast rifles and four smoothbores were taken from Liverpool, England in August 1871 by the USS Worcester and off loaded at Boston Navy Yard. These were manufactured for use on Confederate cruisers. The 9 in (23 cm) rifled cannon number 95 is on private property at Bernhards Bay, New York on Oneida Lake. [29]

In other land battles

A Confederate horse artillery battery, suggested by Colonel Turner Ashby, was organized November 11, 1861. [36] R. Preston Chew's battery, the initial battery of the unit, was originally called Ashby's Horse Artillery. The battery was engaged in Stonewall Jackson's Shenandoah Valley Campaign (1862). [37] [fn 7] According to historian Jennings C. Wise, the armament of the battery "from first to last consisted of 3 pieces; a Blakely imported British rifled piece, which fired a percussion shell; a smooth-bore 12-pounder howitzer; and a 3-inch iron rifle." [38]

Four surviving 3.5-inch Blakely's have been placed at Shiloh National Military Park. [39]

A July 3, 1862 letter from Frank M. Coker of the Sumter Flying Artillery to his wife mentions that during the Seven Days Battles he was ordered to carry a large Blakely rifled gun down the line. [40]

The Confederate Army of Northern Virginia had a variety of artillery pieces at the Battle of Antietam. Many Confederate pieces were inferior models compared to most of those used by the Union Army of the Potomac. [41] Blakely rifles were among the better rifled models used by the Confederates at that battle. [42] Confederate batteries performed well despite being hampered by the frequent deployment of four different cannon in a battery. [43] John B. Brockenbrough's battery, which was heavily engaged in the battle north and west of the Dunker Church, had four different cannon, including a Blakely rifle. [44]

Chew's Battery fought at the Battle of Fairfield, one of the cavalry battles on July 3, 1863, the third day of the Battle of Gettysburg. [45] Blakely rifles, as the most commonly imported British artillery guns, continued in service through the war. Chew's Battery served through the rest of the war concluding with the Appomattox campaign. [46]

An example of an 18-pounder, 4-inch caliber based on bore dimension was captured in the Union attack on Confederates salvaging the blockade runner Hebe near Fort Fisher, North Carolina on August 23, 1863 has been placed in the Washington Navy Yard. Ripley wrote that this should be catalogued as in field service due to its known employment. [47]

The U.S. National Park Service has noted that Blakely rifled cannon were used at several battles of the American Civil War in the Shenandoah Valley (Jackson's Valley campaign; Valley campaigns of 1864). [fn 8]

At Sea

Blakely rifles were used by the Confederate ship SS Georgiana, which was run aground and scuttled on the night of March 19, 1863, while attempting to run past the Union Blockade and into port at Charleston, South Carolina on its first voyage. [48] Two 2.9-inch iron Blakely rifles were recovered from the wreck in 1974. [16] [fn 9] [49]

The commerce raider CSS Alabama carried a 100-pounder Blakely rifled gun in the forecastle. [50] [51] The wreck of the Alabama, which was sunk by the USS Kearsarge on June 19, 1864, off Cherbourg, France was found in 1984 and the 3.5-ton Blakely rifle that was the Alabama's forward pivot gun was recovered from the wreck. [52] Surviving 7-inch Navy rifles are at the Washington Navy Yard and at Cannes, France. [53] Historian Warren Ripley noted that if the shell from Alabama's Blakely rifle which lodged in the Kearsarge's rudder post had exploded, the outcome of the battle might have been different. [54]

The CSS Florida (cruiser) also carried two 7-inch and four 6-inch Blakely guns. [55] [56] A 7-inch Blakely rifle displayed as a trophy at Washington Navy Yard was taken from the "Anglo-Rebel Pirate Florida". [22]

Union rejection of a Blakely

In 1863, the U.S. government rejected a 7-inch Blakely smoothbore with obvious manufacturing defects and non-conformity with specifications. Also, the piece was marked as manufactured by Blakely Ordnance Company, a known Confederate supplier not used by the Union army, contrary to representations by the agent, that it would be made by Sheffield. [57]

Other surviving pieces

Survivors of several variations of 3.5-inch (and possible or worn 3.6-inch 12-pounder) Blakely wrought iron rifles can be found at Shiloh National Military Park (4); West Point, New York, (2); Beaufort, South Carolina; Chickamauga and Chattanooga National Military Park, Tennessee unit; Gettysburg National Military Park; Warren, Pennsylvania; Rock Island Arsenal, Illinois; Charleston, South Carolina; [fn 10] Greenwood, Mississippi (Fort Pemberton Memorial Park); Wortham, Texas; and Winona, Minnesota. [39] A survivor was stolen from Rivers Bridge State Historic Site near Barnwell, South Carolina on February 2, 1995. [39] The only known survivor of a 3.75-inch Blakely wrought iron rifle can be found at Grant Park in Galena, Illinois. [58] [59]

  2. Blakely's patent, February 27, 1855, described Blakely's ordnance improvement as: "a method of forming guns with an internal tube or cylinder of cast iron or steel, enclosed in a casing of wrought iron or steel. I sometimes form the outer surface of the inner tube somewhat conical, the greatest diameter being just in front of the trunnions, and tapering both ways, and apply the outer casing in the form of collars or rings driven thereon. And in some cases I apply two or more layers of such rings, according to the strength sought to be obtained, the trunnions being of one piece with one of the rings. The other casing may, however, be applied in the form of collars or rings, heated and shrunk upon the cylindrical surface of the inner cylinder or tube...." Hazlett, 2004, p. 196.

  9. Recovered projectiles from the Georgiana were 2.890 in diameter, which helped identify the gun as a 2.9-inch Blakely Rifle, Type 11. The salvors noted that the markings on one or both trunnions of the gun when it was recovered were "VAVASSEUR 1862 LONDON." The marking on the top of the reinforcement band was: BLAKELY'S PATENT." Hazlett, 2004, p. 197.
  10. Ripley, 1970, p. 153 wrote that rust has corroded the bore and the apparent 3.75-inch diameter was probably originally closer to 3.5-inch. At page 154, Ripley states that it is more likely to be a Confederate-made piece with the marking acknowledging the Blakely patent or even a direction to use Blakely ammunition.

<span class="mw-page-title-main">Rodman gun</span> Type of American Civil War–era cannon

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.

<span class="mw-page-title-main">Dahlgren gun</span> 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.

<span class="mw-page-title-main">Brooke rifle</span>

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.

<span class="mw-page-title-main">Field artillery in the American Civil War</span>

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.

<span class="mw-page-title-main">Columbiad</span> Type of large-caliber cannon from the 19th century

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.

<span class="mw-page-title-main">Siege artillery in the American Civil War</span>

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.

<span class="mw-page-title-main">Wiard rifle</span>

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.

<span class="mw-page-title-main">James rifle</span> 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. The rifle was created in 1861.

<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">14-pounder James rifle</span> 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.

<span class="mw-page-title-main">Battery E, 1st Missouri Light Artillery Regiment</span> 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.

<span class="mw-page-title-main">M1841 24-pounder howitzer</span> 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.

<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.

Whistling Dick was a cannon used by Confederate forces during the Siege of Vicksburg in the American Civil War. Named for the sound made when it fired, the cannon is believed to have been a rifled 18-pounder gun, which may have had banding on its breech as reinforcement. Historian Warren Ripley believes that Whistling Dick was most likely a Model 1839 gun, which would have been mostly obsolete by the time of the siege. The cannon believed to have been Whistling Dick dueled with Union Navy ships on May 22, 1863, before being transferred to a different location on May 29. The piece would have been captured by Union forces when the siege ended on July 4, 1863, and its fate is unknown. A cannon at the United States Military Academy was incorrectly identified as Whistling Dick, but historian Ed Bearss demonstrated that the USMA piece was actually another Confederate cannon from Vicksburg, the Widow Blakely.
