History

It was developed as a response to combat experience gained in the Boer War and entered service in 1904, replacing the Ehrhard QF 15 pounder and BL 12 pounder 6 cwt. It was intended as a rapid-firing and highly-mobile yet reasonably powerful field gun for Royal Horse Artillery batteries attached to Cavalry divisions, which were expected to be engaged in mobile open warfare.

The original Mk I barrel was wire wound.[2] Later Mk II barrels had a tapered inner A tube [1] which was pressed into the outer tube.

The first British artillery round on the Western Front in World War I was fired by No. 4 gun of E Battery Royal Horse Artillery on 22 August 1914, northeast of Harmignies in Belgium.[3]

It saw action most famously at the Battle of Le Cateau in August 1914 as the British Expeditionary Force retreated from Mons.

It was used to great effect by "L" Bty, Royal Horse Artillery in its famous defensive action on September 1 1914 at Néry, France, for which 3 Victoria Crosses were awarded. The medals and No. 6 gun involved in this action are exhibited at the Imperial War Museum, London.

From late 1914, when the Western Front settled into trench warfare, the 13-pounder was found to be too light to be truly effective against prepared defensive positions. As a result, it was increasingly supplanted by the 18-pounder.

As the war progressed, however, the increasing air activity created a requirement for a medium anti-aircraft gun. Redundant 13-pounders were slightly modified to become "Ordnance QF 13 pdr Mk III" and mounted on high-angle mounts to produce what became known as the 13 pounder 6 cwt anti-aircraft gun.

In 1940, some 13-pounders were brought out of store for use as emergency anti-tank guns, mounted in pill boxes[4], for the home defence of Britain against possible German invasion.

For combat purposes the gun is long obsolete, yet it remains in service with the King's Troop, Royal Horse Artillery for ceremonial and salute purposes.[1]
