After the assassination of Shah Sujah in 1842, the battery was transferred to the Bengal Army of the Honourable East India Company.

It remained loyal during the Indian Rebellion of 1857 and took part in the Siege of Delhi where its commander, George Renny, won the Victoria Cross.

Temporarily reroled to Javelin prior to being the first Troop to convert to the new weapon system HVM starstreak mounted on the Stormer AFV.

The battery was formed on 13 September 1838 as Shah Sujah's Troop, Horse Artillery[1] at Delhi and Meerut.

It was raised as part of Shah Sujah's force of 6,000 troops which invaded Afghanistan in an attempt to restore him to power.

[4] By the time the Indian Rebellion of 1857 broke out, the Bengal Horse Artillery had grown to 13 batteries, organized as three brigades.

[5] Shah Sujah's Troop remained loyal and it took part in the Siege of Delhi where its commander, George Renny, won the Victoria Cross.

Henceforth, batteries were designated in a single alphabetical sequence in order of seniority from date of formation.

[1] Equipped with six 12 pounders,[11][12] the battery was sent to South Africa with the 1st Cavalry Brigade[13][d] and saw active service in the Second Boer War, notably at the Battle of Paardeberg (27 February 1900).

[12] It was still assigned to XI Brigade (though U Battery was at Lucknow in India) and was stationed at Abbassia, Cairo serving in the Force in Egypt.

[20] It returned to Europe and joined XIV Brigade, 7th Division on the Western Front on 21 December 1914.

[27] XIV Brigade was disbanded in Germany in May 1919[24] and in June the battery returned to the United Kingdom and was stationed at Aldershot and Newbridge.

[28] In contrast, Frederick says it joined IV Brigade, RHA[29] which was at Newbridge and Kilkenny with I and L Batteries.

[30] In either case, the new organisation was short-lived as the usual post-war reductions took their toll and the Royal Horse Artillery was reduced to five brigades and 15 batteries.

[1] In commemoration of its origins, the Honour Title "Shah Sujah's Troop" was officially granted to the battery on 13 October 1926.

[33][36] On 27 June 1941 it departed India and arrived in Iraq on 3 July where it was assigned to the 2nd Indian Armoured Brigade Group.

[39] On 15 November 1943, the regiment left the Indian establishment and was assigned to the 7th AGRA (Army Group Royal Artillery).

[41] Plans were put in place at the end of 1946 to create a total of eight RHA regiments to form the artillery element of the 6th and 7th Armoured Divisions in the British Army of the Rhine.

[1] Initially formed in the BAOR in October 1946, the decision was rescinded in March 1947 before the regiment was fully constituted.

[44] Equipped with 17 pounder anti-tank guns, it was initially based in Palestine from May 1947 before returning to England (Woolwich) briefly in 1948.

[44] On arrival in Germany, 12th Regiment was converted to the anti-aircraft role as part of 6th Armoured Division and the battery was re-equipped with Bofors guns (initially with the L/60 variant, later L/70).

From 25 Nov 1971 to 17 Mar 1972 it undertook the first of nine roulement tours to Northern Ireland (Operation Banner) in the infantry role, either with 12th Regiment or separately.

Temporarily reroled to Javelin prior to being the first Troop to convert to the new weapon system HVM starstreak mounted on the Stormer AFV.
