Combat service
Second Boer War
Major D Hall states that in the Second Boer War the Lyddite shells often failed to detonate; the gun was too heavy to be used as a field howitzer, and for siege use its range was too short and shell too light. However, it achieved some success in Natal when able to get close enough to bombard Boers in trenches. [6]
World War I
By 1908 it was obsolete and replaced in British Regular Army brigades by the modern QF 4.5-inch howitzer.
Territorial Force brigades, however, continued to use the howitzer in World War I into 1916, including notably at the ANZAC and Suvla beachheads, Gallipoli, and in the East African campaign.
A lighter 40-pound (18.14 kg) shell with Amatol filling replaced the original 50-pound (22.68 kg) Lyddite shell early in World War I Together with an increase in cordite propellant from 11 oz 7 drams to 14 oz 5 drams, this increased the maximum range from 4,800 to 6,500 yards (5,900 m). Administrative error led to the new 40-pound shells being sent to Gallipoli without range tables or fuze keys for the new pattern fuzes, rendering them useless. [7]
The Ordnance BL 2.75-inch mountain gun was a screw gun designed for and used by the Indian Mountain Artillery into World War I.
The Ordnance BL 60-pounder was a British 5 inch (127 mm) heavy field gun designed in 1903–05 to provide a new capability that had been partially met by the interim QF 4.7 inch Gun. It was designed for both horse draft and mechanical traction and served throughout the First World War in the main theatres. It remained in service with British and Commonwealth forces in the inter-war period and in frontline service with British and South African batteries until 1942 being superseded by the BL 4.5 inch Medium Gun.
This article explains terms used for the British Armed Forces' ordnance and also ammunition. The terms may have slightly different meanings in the military of other countries.

The Ordnance BL 6 inch 26cwt howitzer was a British howitzer used during World War I and World War II. The qualifier "26cwt" refers to the weight of the barrel and breech together which weighed 26 long hundredweight (1.3 t).
The Ordnance BL 6 inch 30cwt howitzer was a British medium howitzer used in the Second Boer War and early in World War I. The qualifier "30cwt" refers to the weight of the barrel and breech together which weighed 30 hundredweight (cwt) : 30 × 112 lb = 3,360 lb. It can be identified by the slightly flared shape of the muzzle and large recuperator springs below the barrel.
The BL 6-inch gun Mark VII was a British naval gun dating from 1899, which was mounted on a heavy travelling carriage in 1915 for British Army service to become one of the main heavy field guns in the First World War, and also served as one of the main coast defence guns throughout the British Empire until the 1950s.

They were also mounted on various wheeled carriages to provide the British Army with a long range gun. They all had a barrel of 40 calibres length.
The Ordnance BL 15-pounder, otherwise known as the 15-pounder 7 cwt, was the British Army's field gun in the Second Boer War and some remained in limited use in minor theatres of World War I. It fired a shell of 3-inch diameter with a maximum weight of 15 pounds (6.8 kg), hence its name which differentiated it from its predecessor '12-pounder' 3-inch gun which fired shells weighing only 12.5 pounds (5.7 kg).
The Ordnance BL 12-pounder 6 cwt was a lighter version of the British 12-pounder 7 cwt gun, used by the Royal Horse Artillery in the late 19th and early 20th centuries.

The BL 12 inch naval gun Mk I was a British rifled breech-loading naval gun of the early 1880s intended for the largest warships such as battleships and also coastal defence. It was Britain's first attempt to match the large guns being installed in rival European navies, particularly France, after Britain transitioned from rifled muzzle-loading guns to the modern rifled breech-loaders somewhat later than the European powers. Mks I - VII all had a barrel of approximately 303 inches in length and similar performance.
The BL 9.2-inch Mk I–VII guns were a family of early British heavy breechloading naval and coast defence guns in service from 1881 to the end of World War I. They were originally designed to use the old gunpowder propellants.
The BL 6-inch gun Marks II, III, IV and VI were the second and subsequent generations of British 6-inch rifled breechloading naval guns, designed by the Royal Gun Factory in the 1880s following the first 6-inch breechloader, the relatively unsuccessful BL 6-inch 80-pounder gun designed by Elswick Ordnance. They were originally designed to use the old gunpowder propellants but from the mid-1890s onwards were adapted to use the new cordite propellant. They were superseded on new warships by the QF 6-inch gun from 1891.
The BL 10 inch guns Mks I, II, III, IV were British rifled breechloading 32-calibre naval and coast defence guns in service from 1885.
The QF 4-inch gun Mks I, II, III were early British QF (quick-firing) naval guns originating in 1895. They all had barrels of 40 calibres length.
The BL 5-inch guns Mk I – Mk V were early British 5-inch rifled breechloading naval guns after it switched from rifled muzzle-loaders in the late 1870s. They were originally designed to use the old gunpowder propellants. The 5-inch calibre was soon discontinued in favour of QF 4.7-inch.
