The Pattern 1907 bayonet, officially called the Sword bayonet, pattern 1907 (Mark I), is an out-of-production British bayonet designed to be used with the Short Magazine Lee Enfield (SMLE) rifle. The Pattern 1907 bayonet was used by the British and Commonwealth forces throughout both the First and Second World Wars.

Design

The Pattern 1907 bayonet consists of a one-piece steel blade and tang, with a crossguard and pommel made from wrought iron or mild steel, and a wooden grip usually of walnut secured to the tang by two screws. The entire bayonet is 21 ³⁄₄ inches (550 mm) long and weighs 16 ¹⁄₂ ounces (470 g), although the weight of production models varied from 16 to 18 ounces (450 to 510 g). Bayonets produced before 1913 feature a hooked lower quillion intended for trapping an enemy's bayonet and possibly disarming opponents when grappling. This was later deemed impractical and replaced with a simpler design from 1913. Often unit armourers subsequently removed the hooked quillion when the bayonet was sent for repair, although there is no evidence that this was officially directed.

The Pattern 1907 bayonet's blade is 17 inches (430 mm) long. A shallow fuller was machined into both sides of the blade, 12 inches (300 mm) long and extending to within 3 inches (76 mm) of the tip, with variations due to the judgement of individual machinists.

The Pattern 1907 bayonet was supplied with a simple leather scabbard fitted with a steel top-mount and chape, and usually carried from the belt by a simple frog. The Pattern 1907 bayonet attaches to the SMLE by a boss located below the barrel on the nose of the rifle and a mortise groove on the pommel of the bayonet.

The combined length of the SMLE and Pattern 1907 bayonet is 5 feet 2 inches (1.57 m).

Markings

Official marks were stamped onto the Pattern 1907 bayonet's ricasso. On British manufactured bayonets the right side includes an 'X' bend-test mark, a broad arrow government acceptance mark, and one or more Royal Small Arms Factory appointed inspector's marks, on the left side is the date of the bayonet's official inspection and the maker's name and the reigning monarch's crown and royal cypher, "ER" (Edward Rex) or after 1910 "GR" (Georgius Rex), the latter being the Latinised version of the king's name.

Indian bayonets were marked similarly to British bayonets except the royal cypher read "GRI" (Georgius Rex Imperator) and the manufacturer's mark was 'R.F.I.' (Rifle Factory Ishapore). Australian bayonets differ in the manufacturer's marks, with the Lithgow Company Shield or 'MA' (Lithgow Small Arms Factory) or 'OA' (Orange Feeder Factory for the Lithgow Small Arms Factory). The wooden grips of World War II–era Australian bayonets were often marked 'SLAZ' for Slazenger, who made the grips during that war.

History

When the British military adopted the Short Magazine Lee-Enfield rifle, its barrel was shortened to 25.2 inches (640 mm), 5 inches (130 mm) shorter than the preceding Magazine Lee-Enfield. British military strategists were fearful that the British infantry would be at a disadvantage when engaged in a bayonet duel with enemy soldiers who retained a longer reach. Bayonet fighting drills formed a significant part of a contemporary British infantryman’s training. Soldiers were drilled in various stances and parrying techniques against an enemy also armed with rifle and bayonet. The combined length of the SMLE and the in-service Pattern 1903 bayonet, which had a 12-inch (300 mm) blade, was 4 feet 9 inches (1.45 m), shorter than the contemporary French Lebel Model 1886 at 6 feet (1.8 m) and the German Mauser 1898 at 5 feet 10 inches (1.77 m).

Japanese Arisaka, Type 30 bayonet.

In 1906–1907, the British Army conducted trials to find a new longer standard issue bayonet. Experiments were conducted with a number of foreign bayonet designs, including a modified version of the other and the Japanese Type 30 bayonet. The trials resulted in the British Army adopting its own version of the Type 30 bayonet. The new design was designated Sword bayonet, pattern 1907 (Mark I) and was officially introduced on 30 January 1908.

Approximately 5,000,000 Pattern 1907 bayonets were made in Britain during World War I. The makers were Wilkinson Sword, Sanderson Brothers & Newbould Ltd, James A. Chapman, Robert Mole & Sons, and Vickers Ltd. Additionally, Remington UMC produced approximately 100,000 during the war. The Pattern 1907 bayonet was manufactured in India from 1911 to 1940 at the Rifle Factory Ishapore and in Australia from 1913 to 1927, and then again between 1940 and 1945 at the Lithgow Small Arms Factory.

The Pattern 1907 bayonet was adopted by most of the British Commonwealth along with the SMLE. It saw broad front-line service until 1945, seeing service in both World War I and World War II. It remained in Australian and Indian service for some time after 1945.

In 1926, the 1907 bayonet was reclassified as the 'Bayonet, No.1, Mk.1'.

Variants

Pattern 1913 bayonet

The Pattern 1913 bayonet was designed to be used with the experimental Pattern 1913 Enfield. The Pattern 1913 bayonet's only functional difference from the Pattern 1907 bayonet is a longer cross guard for the muzzle ring, to fit the Pattern 1913 Enfield rifle. Upon the outbreak of World War I the British authorities adapted the Pattern 1913 Enfield to the .303 British cartridge, creating the Pattern 1914 Enfield rifle, and contracts were awarded to the United States arms manufacturers Winchester, Remington and Eddystone for the rifle's production. To accompany those rifles, Remington manufactured the 1,243,000 Pattern 1913 bayonets and Winchester produced 225,000.

The Pattern 1917 bayonet cannot be fixed to the Lee-Enfield rifle (because of the different muzzle ring heights), so to avoid confusion with the Pattern 1907 bayonet, two deep vertical grooves were cut into the wooden grips of the Pattern 1913 bayonet.

Model 1917 bayonet

Upon their entry into World War I, the United States military adapted the Pattern 1914 Enfield rifle to the .30-06 Springfield cartridge to make up for shortfalls in production of the Model 1903 Springfield rifles, creating the substitute standard Model 1917 Enfield rifle. To accompany the M1917 rifle, the United States simply adopted the Pattern 1913 bayonet as the Model 1917 bayonet. Over 2,000,000 Model 1917 bayonets were manufactured in the United States during the war, including 545,000 Pattern 1913 bayonets manufactured for but not delivered to the British military, that were simply re-stamped as Model 1917 bayonets. The Model 1917 bayonet was adopted unchanged to be used with United States Army combat shotguns. After the war, the M1917 bayonet was retained for use with combat shotguns, and remained in United States service until the 1980s.

India Pattern bayonets

From 1941, India began cutting down Pattern 1907 bayonets to 12.2 in (310 mm) and grinding a point into the remaining blade, creating the India Pattern No. 1 Mk. I*. The India Pattern No. 1 Mk. I** is almost identical except a false edge 2 in (51 mm) long is ground into the top of the blade. Both are recognisable by the fuller, which runs the length of the blade. The India Pattern No. 1 Mk. II and the India Pattern No. 1 Mk. II* are versions freshly manufactured with 12.2-inch blades that have no fuller (rather than being cut down from longer bayonets), the latter having a false edge on top side. Both retain the Pattern 1907 hilt and grip. The India Pattern No. 1 Mk. III and the India Pattern No. 1 Mk. III* are similar to the No. 1 Mk. II and No. 1 Mk. II* except they have crude squared pommels and rectangular grips, and are finished with black paint.
