The '''M1857 12-pounder Napoleon''' or '''Light 12-pounder gun''' was a bronze smoothbore muzzle-loading 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 [[Second French Empire|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 {{cvt|12.3|lb|kg|1}} [[round shot]] [[shell (projectile)|shell]] up to a distance of {{cvt|1,619|yd|m|0}} at 5° elevation. It could also fire [[canister shot]], [[shell (projectile)|common shell]], and [[shrapnel shell|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 US Army, while replacement of these older weapons was slower in the [[Confederate States Army]]. A total of 1,157 were produced for the US Army, all but a few in the period 1861–1863. The [[Confederate States of America]] utilized captured US 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. |

Background
In the period before the Civil War, a US Army light artillery battery was organized with four M1841 6-pounder field guns and two M1841 12-pounder howitzers.[1] The field gun fired solid iron cannon balls in a flat trajectory to smash its targets[2] while the howitzer was designed to lob hollow shells into massed formations or fortifications.[3] Napoleon III realized that mixing field guns and howitzers within an artillery battery caused the logistical problem of having to carry two types of ammunition. He understood that batteries might become more effective if a single gun could fire both the round shot of the field gun and the common shell and spherical case shot of the howitzer. (Both field guns and howitzers were already capable of firing canister shot.) The French gun designers' solution to the problem was the invention of the canon obusier de 12 or 12-pounder gun-howitzer. By 1856, this new weapon had been adopted by France, Austria, Prussia, Saxony, and Russia. An American military commission sent to Europe in 1855–1856 led by Major Alfred Mordecai wrote a report praising the new gun-howitzer[4] and the US Ordnance Department quickly obtained a license to produce the gun.[5]
On 14 December 1856, the Ames Manufacturing Company of Chicopee, Massachusetts received an order to produce a copy of the gun-howitzer, and on 25 March 1857 the Ordnance Department accepted delivery of one 1,187 lb (538 kg) piece for a cost of $546.02. The weapon failed its trial, but in 2004 the original gun could be seen at the Petersburg National Battlefield visitor center. On 28 May 1857, the Ordnance Department ordered four guns of a modified version from Ames and these pieces were delivered on 16 September 1857. The four modified guns were 3 in (76 mm) longer than the original gun and 40 lb (18.1 kg) heavier. These four guns became the standard model for all 12-pounder Napoleons subsequently produced for the US Army. When the Civil War broke out in April 1861, the US Army owned only the original five 12-pounder Napoleons. The US Army needed field artillery and there was no time to experiment with new gun types. Since, the new gun could be produced quickly, orders were placed with Ames and Cyrus Alger & Company of Boston. Later, more contracts were let to Henry N. Hooper & Company and Revere Copper Company, both of Boston, and Miles Greenwood & Company of Cincinnati.[6]
One member of the 1855 American military commission was Captain George B. McClellan who became major general in command of US forces in summer 1861. Like Mordecai, McClellan saw the advantages of using a single artillery piece to combine the functions of both field gun and howitzer. In 1861, McClellan approved the plan offered by his chief of artillery William Farquhar Barry, which included the goal to arm Union Army field artillery batteries exclusively with the light 12-pounder smoothbore, the 3-inch Ordnance rifle, and the Parrott rifle. Each battery was organized so as to contain six guns, if possible, with no less than four guns per battery. By the time of the First Battle of Bull Run, the US Army had only nine 12-pounder Napoleons, and by 1 January 1862, it had only 36 Napoleons. In August 1861, 22 Napoleons were ordered[7] and 153 were ordered in October and November 1861. When it became clear that the war would be a long one, many more guns were ordered.[8]
