The Henry repeating rifle is a lever-action, breech-loading, tubular magazine rifle famed both for its use at the Battle of the Little Bighorn and being the basis for the iconic Winchester rifle of the American Wild West.
Designed by Benjamin Tyler Henry in 1860, the Henry was introduced in the early 1860s and produced through 1866 in the United States by the New Haven Arms Company. It was adopted in small quantities by the Union in the Civil War, favored for its greater firepower than the standard issue carbine. Many later found their way West, notably in the hands of the Sioux and Cheyenne in their obliteration of Custer's U.S. Cavalry troops in June 1876.
The original Henry rifle was a sixteen shot .44 caliber rimfire, lever-action, breech-loading rifle patented by Benjamin Tyler Henry in 1860 after three years of design work. The Henry was an improved version of the earlier Volition Repeating Rifle, and later Volcanic Repeating Rifle. The Henry used copper (later brass) rimfire cartridges with a 216 grain (14.0 gram, 0.490 ounce) bullet over 25 grains (1.6 g, 0.056 oz.) of gunpowder. Production was very small (150 to 200 a month) until the middle of 1864. Nine hundred were manufactured between summer and October 1862; by 1864, production had peaked at 290 per month, bringing the total to 8,000 manufactured. By the time production ended in 1866, approximately 14,000 units had been manufactured.
For a Civil War soldier, owning a Henry rifle was a point of pride. Letters home would call them "Sixteen" or "Seventeen" Shooters, depending whether a round was loaded in the chamber. Just 1,731 of the standard rifles were purchased by the government during the Civil War. The Commonwealth of Kentucky purchased a further 50. However 6,000 to 7,000 saw use by the Union on the field through private purchases by soldiers who could afford it. The relative fragility of Henrys compared to Spencer repeating rifles hampered their official acceptance. More Henrys were purchased by soldiers than by the government. Many infantry soldiers purchased Henrys with their reenlistment bounties of 1864. Most of these units were associated with Sherman's Western Troops.
When used correctly, the brass framed rifles had an exceptionally high rate of fire compared to any other weapon on the battlefield. Soldiers who saved their pay to buy one believed it would help save their lives. Since tactics had not been developed to take advantage of their firepower, Henrys were frequently used by scouts, skirmishers, flank guards, and raiding parties rather than in regular infantry formations. To the amazed muzzleloader-armed Confederates who had to face this deadly "sixteen shooter", it was called "a rifle that you could load on Sunday and shoot all week long." Those few Confederate troops who came into possession of captured Henry rifles had little way to resupply the special ammunition used by the weapon, making its widespread use by Confederate forces impractical. The rifle was, however, known to have been used at least in part by some Confederate units in Louisiana, Texas, and Virginia, as well as the personal bodyguards of Confederate President Jefferson Davis.
The Henry rifle used a .44 caliber cartridge with 26 to 28 grains (1.7 to 1.8 g) of black powder. This gave it significantly lower muzzle velocity and energy than other repeaters of the era, such as the Spencer. The lever action, on the down-stroke, ejected the spent cartridge from the chamber and cocked the hammer. A spring in the magazine forced the next round into the follower; locking the lever back into position pushed the new cartridge into the chamber and closed the breech. As designed, the Henry lacked any form of safety. When not in use its hammer rested on the cartridge rim; any impact on the back of the exposed hammer could cause a chambered round to fire. If left cocked, it was in the firing position without a safety. Current Henry models will not fire if dropped or the hammer is released partially by accident. It can be safely carried with a chambered round both hammer cocked or hammer down. From owners manual "This firearm is designed with an ultra-safe patented Transfer Bar Safety Mechanism. This safety system prevents the gun from being fired under all circumstances, except when the hammer is fully cocked and the trigger is pulled. If the hammer is fully cocked and the trigger is pulled, the gun would fire as normal. However, if the hammer is fully cocked and is accidentally dislodged by some other means other than the trigger being pulled, the gun will not fire. If the hammer is in the process of being cocked and is accidentally released and dropped into the fired down position, before it is fully cocked, the gun will not fire. This rifle can be safely carried fully loaded with the hammer in the fired down resting position. Please note that this rifle does not have a half cock safety position nor a crossbolt safety." 
To load the magazine, the shooter moves the cartridge-follower along the slot in the top portion of the magazine-tube and pivots it to the right to open the front-end of the magazine. Then, he loads the 15 cartridges one by one. When full, he pivots the top portion back and release the follower.
While never issued on a large scale, the Henry rifle demonstrated its advantages of rapid fire at close range several times in the Civil War and later during the wars between the United States and the Plains Indians. Examples include the successes of two Henry-armed Union regiments at the Battle of Franklin against large Confederate attacks, as well as the Henry-armed Sioux and Cheyenne's destruction of the 7th Cavalry at Little Big Horn.
Manufactured by the New Haven Arms Company, the Henry rifle evolved into the famous Winchester Model 1866 lever-action rifle. With the introduction of the new Model 1866, the New Haven Arms Company was renamed the Winchester Repeating Arms Company.
Uberti produces an almost exact copy Henry Model 1860 chambered in .44-40 Winchester or .45 Colt, rather than the original .44 Henry rimfire. Distributed by several companies, these replicas are popular among Cowboy Action Shooters and Civil War reenactors, as well as competition shooters in the North-South Skirmish Association(N-SSA).
