The RML 9-pounder 8 cwt gun and the RML 9-pounder 6 cwt gun were British Rifled, Muzzle Loading (RML) field, horse and naval artillery guns manufactured in England in the 19th century, which fired a projectile weighing approximately 9 pounds (4.1 kg). "8 cwt" and "6 cwt" refers to the weight of the gun to differentiate it from other 9-pounder guns.
Service history
The 9-pounder 8 cwt Rifled Muzzle Loader was the field gun selected by the Royal Artillery in 1871 to replace the more sophisticated RBL 12 pounder 8 cwt Armstrong gun, which had acquired a reputation for unreliability.[1] The gun was rifled using the system developed by William Palliser, in which studs protruding from the side of the shell engaged with three spiral grooves in the barrel.[2] In 1874, a 6 cwt version was introduced for horse artillery and was later adopted for field artillery use, replacing the 8 cwt version. All variants used the same ammunition, which took the form of shrapnel shell, case shot and common shell.[1]
The 9-pounder remained in front-line service with the Royal Artillery until 1878 when the RML 13 pounder 8 cwt gun was introduced, however it remained in use with colonial forces until 1895 and saw action in the Anglo-Zulu War of 1879, the First Boer War of 1881[1] and the Anglo-Egyptian War in 1882.[3] A number were issued to British Artillery Volunteer units, with the 1st Ayrshire and Galloway Artillery Volunteers being issued with some guns as late as 1901.[4]
Variants
- 9-pounder 8 cwt Mark I (Land Service): Introduced into the Royal Artillery in 1871. It was later withdrawn and modified for sea service.
- 9-pounder 8 cwt Mark II (Naval Service): Introduced in 1873 by the Royal Navy.
- 9-pounder 6 cwt Mark I (N.S.): A few were made for experimental trials but they proved to be too short; some were issued to the Royal Indian Navy. In 1873, forty five were completed for use as boat guns.
- 9-pounder 6 cwt Mark II (L.S.): A new design in 1874 for the Royal Horse Artillery, it was longer than the 8 cwt gun but had the same carriage.
- 9-pounder 6 cwt Mark III (N.S.): Introduced in 1879, a modified Mark II for naval service.
- 9-pounder 6 cwt Mark IV (N.S.): Similar to the Mark III with a steel jacket instead of wrought iron previously used, and with a strengthened cascabel.[5]
