Model 1816 Musket

The War of 1812 had revealed many weaknesses in American muskets. The Springfield Model 1812 was created in an attempt to improve both the design and manufacture of the musket. The Model 1816 made further improvements, and replaced the Model 1812. The Model 1812 had borrowed heavily from the design of the French Charleville Model 1777, and this design was retained for the Model 1816. The Model 1816 had a 42-inch (110 cm) long.69 caliber smoothbore barrel, similar to the Model 1812, but had a longer lockplate, a shorter trigger guard, and a longer bayonet than the Model 1812. The Model 1816 also had a more straight lined stock. The overall length of the weapon was 58 inches (150 cm). The Model 1816 musket was originally manufactured at the Springfield and Harpers Ferry armories along with independent contractors between 1816 and 1844. Around 700,000 were made, more than any other flintlock in U.S. history. The Model 1816 was originally manufactured as a flintlock musket. Like other flintlock muskets, many were later converted to percussion lock, as the percussion cap system was much more reliable and weather resistant. Some also had their barrels rifled later as well to fire the newly created Minié ball, if the barrel was thick enough to be structurally sound. However, the increased breech pressure generated by the new expanding projectile was too powerful for the conversion process and older musket barrels to hold and rifled Model 1816 muskets were instead issued standard.69 caliber round balls. The Model 1816 musket was used by Texans during the Texas Revolution, which subsequently became standard issue for the Texan military in 1839, and by the U.S. Army and militia during the Mexican–American War. During this conflict, the flintlock version of the Model 1816 was preferred by U.S. regular forces, due to percussion cap supply concerns. Nauvoo Legion engaged in frontier skirmishes, conducting patrols and punitive expeditions using smoothbore muskets in Wakara's War. The unit primarily utilized guerrilla tactics, employing small arms such as percussion-converted Model 1816 muskets type III, against forces of the U.S. government during the Utah Campaign. It was also used during the early years of the American Civil War (War Between the States) until around 1862. The large majority of Model 1816 muskets had been converted to percussion firing by 1860. Muskets made prior to 1821 were considered too outdated to be serviceable weapons and many were not converted. Most of them were in Confederate arsenals and a large number of Confederate forces for the first year of the Civil War had the misfortune of carrying flintlock muskets, some of which dated back to the War of 1812. Many improvements to the Model 1816 were made, producing the Springfield Model 1822, Springfield Model 1835, Springfield Model 1840, and Springfield Model 1842. U.S. Ordnance Department referred to these as different models, but in other U.S. government documents they are referred to as a continuation of the Model 1816 with the first model designated as the Type I, the Model 1822 as the Type II, and the Model 1835 as the Type III. Modern histories are similarly inconsistent in the nomenclature of these weapons.
