The Martini–Henry is a breech-loading single-shot rifle with a lever action that was used by the British Army. It first entered service in 1871, eventually replacing the Snider–Enfield, a muzzle-loader converted to the cartridge system. Martini–Henry variants were used throughout the British Empire for 47 years. It combined the dropping-block action first developed by Henry O. Peabody (in his Peabody rifle) and improved by the Swiss designer Friedrich von Martini, combined with the polygonal rifling designed by Scotsman Alexander Henry.

Though the Snider was the first breechloader firing a metallic cartridge in regular British service, the Martini was designed from the outset as a breechloader and was both faster firing and had a longer range.^[6]

The Martini–Henry was copied on a large scale by North-West Frontier Province gunsmiths. Their weapons were of a poorer quality than those made by Royal Small Arms Factory, Enfield, but accurately copied down to the proof markings. The chief manufacturers were the Adam Khel Afridi, who lived around the Khyber Pass. The British called such weapons "Pass-made rifles".

Overview[edit]

In the original chambering, the rifles fired a round-nosed, tapered-head .452-inch, soft hollow-based lead bullet, wrapped in a paper patch giving a wider diameter of .460 to .469-inch; it weighed 485 grains.^[6] It was crimped in place with two cannelures (grooves on the outside neck of the case), ahead of two fibre card or mill board disks, a concave beeswax wad, another card disk and cotton wool filler. This sat on top of the main powder charge inside initially a rimmed brass foil cartridge, later made in drawn brass.

The cartridge case was paper lined so as to prevent the chemical reaction between the black powder and the brass. Known today as the .577/450, a bottle-neck design with the same base as the .577 cartridge of the Snider–Enfield. It was charged with 85 grains (5.51 g) of Curtis and Harvey's No.6 coarse black powder,^[6] notorious for its heavy recoil.^[7] The cartridge case was ejected to the rear when the lever was operated.

The rifle was 49 inches (1,245 mm) long, the steel barrel 33.22 inches (844 mm). The Henry patent rifling produced a heptagonal barrel with seven grooves with one turn in 22 inches (559 mm). The weapon weighed 8 pounds 7 ounces (3.83 kg). A sword bayonet was standard issue for non-commissioned officers; when fitted, the weapon extended to 68 inches (1,727 mm) and weight increased to 10 pounds 4 ounces (4.65 kg).

The standard bayonet was a socket-type spike, either converted from the older Pattern 1853 (overall length 20.4 inches (518 mm)) or newly produced as the Pattern 1876 (overall length 25 inches (635 mm)), referred to as the "lunger".^[7] A bayonet designed by Lord Elcho was intended for chopping and other sundry non-combat duties, and featured a double row of teeth so it could be used as a saw; it was not produced in great numbers and was not standard issue.

The Mk II Martini–Henry rifle, the most numerous modification adopted in 1877,^[8] as used in the Zulu Wars, was sighted to 1,800 yards (1,600 m). At 1,200 yards (1,100 m), 20 shots exhibited a mean deflection from the centre of the group of 27 inches (69 cm), the highest point on the trajectory was 8 feet (2.44 m) at 500 yards (460 m). In 1879, Mk III rifle was adopted, which had minor design updates as well as more interchangeable parts with Martini-Henry carbine.^[9]

In late 1870s British military was looking forward to unify ammunition for its rifles and machine guns (they were both .45 caliber, but different cartridges). The .577/.450 turned out to be poorly suited to the hopper feed as well as existing box magazines due to a very pronounced bottleneck, so in 1881 the Gatling cartridge was tried in Martini-Henry rifles.^[10] However, in parallel developing a new cartridge with a lighter approximately .4 inch bullet was considered since 1880, and after its design was settled on in 1885 a new variant of the rifle for it was approved in April 1886, designated Enfield Martini .4-inch Pattern A.^[10][11] It incorporated several minor improvements such as a safety catch, was gradually phased in to replace the Martini–Henry with over 21k produced overall. The replacement was planned to be gradual, to use up existing stocks of the old ammunition. A year later a modified Pattern B was approved with tens of thousands more produced.^[10][12]

However, before this was complete, the decision was made to replace the Martini–Henry rifles with the .303 calibre bolt-action magazine Lee–Metford, which gave a considerably higher maximum rate of fire. Consequently, to avoid having three different rifle calibres in service, the Enfield–Martinis were withdrawn, converted to 0.45 calibre, and renamed Martini–Henry Mk IV "A", "B" and "C" pattern rifles. Some 0.303 calibre black-powder carbine versions were also produced, known as the Martini–Metford, and even 0.303 calibre cordite carbines, called Martini–Enfields (the former name for the type of action and the latter name for the pattern of rifling).

During the Martini–Henry's service life the British Army was involved in a large number of colonial wars, most notably the Anglo-Zulu War in 1879. The rifle was used in the Battle of Isandlwana, and by the company of the 2nd Battalion, 24th Regiment of Foot at the battle of Rorke's Drift, where 139 British soldiers successfully defended themselves against several thousand Zulus. The weapon was not completely phased out until 1904.

The rifle suffered from cartridge-extraction problems during the Zulu War, mostly due to the thin, weak, pliable foil brass cartridges used: they expanded too much into the rifle's chamber on detonation, to the point that they stuck or tore open inside the rifle's chamber. It would eventually become difficult to move the breech block and reload the rifle, substantially diminishing its effectiveness, or rendering it useless if the block could not be opened. After investigating the matter, the British Army Ordnance Department determined the fragile construction of the rolled brass cartridge, and fouling due to the black-powder propellant, were the main causes of this problem.

To correct this, the weak rolled brass cartridge was replaced by a stronger drawn brass version, and a longer loading lever was incorporated into the MK-IV to apply greater torque to operate the mechanism when fouled.^[6] These later variants were more reliable in battle, although it was not until smokeless nitro powders and copper-jacketed bullets were tried out in these rifles in the 1920s that accuracy and 100% reliability of cartridge case extraction was finally achieved by Birmingham ammunition makers (Kynoch). English hunters on various safaris, mainly in Africa, found the Martini using a cordite charge and a 500-grain full-metal-jacketed bullet effective in stopping large animals such as hippopotamus up to 80 yards away.

The nitro based/shotgun powders were used in Kynoch's .577/450 drawn-brass Martini–Henry cartridge cases well into the 1960s for the commercial market, and again were found to be very reliable and, being smokeless, eliminated fouling issues. The powder's burning with less pressure inside the cartridge case prevented the brass cases from sticking inside the rifle's chamber (because they were not expanding as much as the original black-powder loads did).

The rifle remained a popular competition rifle at National Rifle Association meetings, at Bisley, Surrey, and (NRA) Civilian and Service Rifle matches from 1872 to 1904, where it was used up to 1,000 yards using the standard military service ammunition of the day. By the 1880s the .577/.450 Boxer Henry round was recognised by the NRA as a 900-yard cartridge, as shooting the Martini out to 1,000 yards or (3⁄4 of a mile) was difficult, and took great skill to assess the correct amount of windage to drop the 485 grain bullet on the target. But by 1904 more target shooters were using the new .303 cal. cartridge, which was found to be much more accurate, and thus interest in the .577/450 fell away, to the point that by 1909 they were rarely used at Bisley matches, with shooters favouring the later Lee–Enfield bolt action magazine rifles.^[13]

In 1879, however, it was generally found that in average hands the .577/450 Martini–Henry Mk2, although the most accurate of the Martinis in that calibre ever produced for service life, was really only capable of hitting a man-size target out to 400 yards. This was due to the bullet going subsonic after 300 yards and gradually losing speed thereafter, which in turn affected consistency and accuracy of the bullet in flight. The 415-grain Martini Carbine load introduced in 1878 shot better out to longer ranges and had less recoil when it was fired in the rifles, with its reduced charge of only 75 grains of Curtis & Harvey's. It was found that, while the rifle with its 485 grain bullet shot point of aim to 100 yards, the carbine load when fired in the rifles shot 12 inches (30 cm) high at the same range, but then made up for this by shooting spot-on out to 500 yards (460 m).^[14] These early lessons enabled tactics to be evolved to work around the limitations of this large, slow, and heavy calibre during the Zulu War. During most of the key battles, such as Rorke's Drift and the Battle of Ulundi, the order to volley fire was not given until the Zulus were at or within 400 yards.

The ballistic performance of a .577/450 is somewhat similar to that of an American .45/70 Government round, as used prolifically throughout the American Frontier West and by buffalo hunters, though the .577/450 has more power due to its extra 15 grains of black powder inside the cartridge case. It is clear from early medical field surgeons' reports that at 200 yards the rifle really came into its own, and inflicted devastating and horrific wounds on the Zulus in the Anglo–Zulu War.^[15] The MK2 Martini's sights are marked to 1,800 yards, but this setting was only ever used for long-range mass volley firing to harass an artillery position or a known massed cavalry position, prior to a main fight, and to prevent or delay infantry attacks. A similar "drop volley sight" whereby the rifle's bullets were dropped long range onto the target was employed on the later .303 Lee–Enfield rifles of WW1, which had a graduation lever sight calibrated up to 2,800 yards.

The Nepalese produced a close copy of the British Martini–Henry incorporating certain Westley Richards improvements to the trigger mechanism but otherwise very similar to the British Mark II. These rifles can be identified by their Nepalese markings and different receiver ring. A noticeably different variant incorporating earlier Westley Richards ideas for a flat-spring driven hammer within the receiver in lieu of the coil-spring powered striker of the von Martini design, known as the Gahendra rifle, was produced locally in Nepal.^[16] While generally well-made, the rifles were produced substantially by hand, making the quality extremely variable. Though efforts were being made to phase out these rifles, presumably by the 1890s, some 9000 were still in service in 1906.^[16]

The Martini–Henry saw service in World War I in a variety of roles, primarily as a Reserve Arm, but it was also issued (in the early stages of the war) to aircrew for attacking observation balloons with newly developed incendiary ammunition, and aircraft. Martini–Henrys were also used in the African and Middle Eastern theatres during World War I, in the hands of Native Auxiliary troops.

Greener shotgun[edit]

A shotgun variant known as the Greener Police Gun or the Greener Prison Shotgun was chambered in a 14.5-gauge 2+7⁄8-inch (18×73mm) full-length brass shell used only by this gun. That would make the weapon useless to anyone who stole it, as no other cartridge could be loaded.^[17] It was used by prison guards and police in Egypt, Burma, India, and Australia.^[18] Over 60,000 had been produced by the time production ended in the 1960s.^[19]

The gun was originally designed to replace the Egyptian police's obsolete Martini–Henry rifles, which they usually loaded with brass shot-shells. The Mark I/14 ("14" for the gun's gauge), first produced in 1918, had a full wooden stock and a large metal nosecap over the muzzle. The Mark II/14 lacked the nosecap and had a full hunting-style stock. It was discovered that criminals in Egypt were jury-rigging shotguns they had captured or stolen by wrapping common civilian 16-gauge shells with thick paper to allow them to fit the bore. Greener responded in 1932 by coming up with a redesigned gun and new shell design to prevent this. The Mark III/14 Shotgun had a three-pronged firing pin and its cartridge had a unique recessed primer well (much like that of the Lebel rifle) to prevent the firing of standard shells. The cartridge also had a bottle-necked tapered wall and corresponding shotgun breech that would prevent the insertion of other shells.

An example can be seen at the Royal Armouries Museum in Leeds.^[20]

Greener also used the Martini action for the GP ("General Purpose") single-barreled shotgun firing standard 12-bore 2+3⁄4-inch ammunition, which was a staple for gamekeepers and rough shooters in Britain up to the 1960s.

Greener harpoon gun[edit]

W. W. Greener also used the Martini action to produce the Greener-Martini Light Harpoon Gun used for whaling, and also for commercial harvest of tuna and other large fish.^[21] The gun fired a .38 blank cartridge to propel the harpoon. A special barrel—effectively a hollow tube that acted as a spigot—and stock were fitted to accommodate the harpoon and to lower weight.

Ottoman, Romanian, and Boer Republics Peabody–Martini–Henry rifles[edit]

Unable to purchase Martini–Henry rifles from the British because their entire production was going to rearming British troops, The Ottoman Empire purchased weapons identical to the Mark I from the Providence Tool Company in Providence, Rhode Island, United States (the manufacturers of the somewhat similar Peabody rifle), and used them effectively against the Russians in the Russo-Turkish War (1877–1878).^[22][23] Ottoman outlaws and folk heroes such as Hekimoğlu famously used the rifle during his raids on landowners.^[24] The rifle is referred to as Aynalı Martin in the Ottoman Empire and is featured in several famous folk songs.

Beginning in 1879, Romania decided to replace its old model 1867 Peabody rifles with the Martini–Henry rifles. An order was made to Steyr for 130,000 rifles which were delivered into the early 1880s.^[25] These rifles were also used in the First World War, with 142,906 rifles and 8,724 carbines being registered in service on 15 August 1916.^[26]

Significant numbers of the basic design, with variations, were also produced for the Boer Republics, both in Belgium and, via Westley Richards, in Birmingham, as late as the late 1890s. During the Second Boer War, many of the Boers used the Martini–Henry rifle, since over 34,000 of these had been purchased.^[27]

Operation of the Martini action[edit]

The lock and breech are held to the stock by a metal bolt (A). The breech is closed by the block (B) which turns on the pin (C) that passes through the rear of the block. The end of the block is rounded to form a knuckle joint with the back of the case (D) which receives the force of the recoil rather than the pin (C).

Below the trigger-guard the lever (E) works a pin (F) which projects the tumbler (G) into the case. The tumbler moves within a notch (H) and acts upon the block, raising it into the firing position or allowing it to fall according to the position of the lever.

The block (B) is hollowed along its upper surface (I) to assist in inserting a cartridge into the firing chamber (J). To fire the cartridge the block is raised to position the firing mechanism (K) against the cartridge. The firing mechanism consists of a helical spring around a pointed metal striker, the tip of which passes through a hole in the face of the block to impact the percussion-cap of the inserted cartridge. As the lever (E) is moved forward the tumbler (G) revolves and one of its arms engages and draws back the spring until the tumbler is firmly locked in the notch (H) and the spring is held by the rest-piece (L) which is pushed into a bend in the lower part of the tumbler.

After firing, the cartridge is partially extracted by the lock. The extractor rotates on a pin (M) and has two vertical arms (N), which are pressed by the rim of the cartridge pushed home into two grooves in the sides of the barrel. A bent arm (O), forming an 80° angle with the extractor arms, is forced down by the dropping block when the lever is pushed forward, so causing the upright arms to extract the cartridge case slightly and allow easier manual full extraction.

As well as British service rifles, the Martini breech action was applied to shotguns by the Greener company of Britain, whose single-shot "EP" riot guns were still in service in the 1970s in former British colonies. The Greener "GP" shotgun, also using the Martini action, was a favourite rough-shooting gun in the mid-20th century. The Martini action was used by BSA and latterly BSA/Parker Hale for their series of "Small Action Martini" small bore target rifles that were in production until 1955.
