6th Regiment , Royal Horse Artillery 6th Regiment , Royal Horse Artillery was a Regiment of the Royal Horse Artillery that acted as a training formation during World War II . It was the last RHA unit to serve in India between December 1945 and April 1947 , before being redesignated as 6th Field Regiment , Royal Artillery in Palestine in 1948 . The regiment had an earlier incarnation as F Brigade , RHA , formed from the 2nd Brigade of the Bengal Horse Artillery in 1862 before being broken up in 1877 . It was reestablished in 1901 as VI Brigade , RHA but was broken up at the outbreak of World War I as its constituent batteries were posted to other formations . F Brigade , RHA . The Bengal Army of the Honourable East India Company formed its first battery of Horse Artillery , the " Experimental Brigade , Bengal Horse Artillery " on 4 December 1800 ( still in existence as F Battery , RHA ) . By the time the Indian Rebellion of 1857 broke out , the Bengal Horse Artillery had grown to 13 batteries , organized as three brigades . Five of these batteries were manned by sepoy s ( native Indian soldiers ) and two mutinied : 4th Troop , 1st Brigade at Neemuch and 4th Troop , 3rd Brigade at Multan . All five batteries were promptly reformed as European units . As a result of the Rebellion , the British Crown took direct control of India from the East India Company on 1 November 1858 under the provisions of the Government of India Act 1858 . The Presidency armies transferred to the direct authority of the British Crown and its European units were transferred to the British Army . Henceforth artillery , the mutineers most effective arm , was to be the sole preserve of the British Army ( with the exception of certain Mountain Artillery batteries ) . On 19 February 1862 , the Bengal Horse Artillery transferred to the Royal Artillery as its 2nd and 5th Horse Brigades . On transfer , 5th Horse Brigade , Royal Artillery comprised : The 1st Brigade with 10 batteries was much larger than the other four ( with four to seven batteries each ) . A reorganization of the Horse Artillery on 13 April 1864 saw 1st Brigade split as A and B Brigades , 2nd Brigade become C Brigade , 3rd become D Brigade , 4th become E Brigade , and 5th become F Horse Brigade , Royal Artillery . As battery designations were tied to the brigade the battery was assigned to , the batteries were also redesignated . The new designations were in order of seniority . F Horse Brigade , RA now comprised : From 1866 , the term " Royal Horse Artillery " appeared in Army List hence the brigade was designated F Brigade , Royal Horse Artillery from about this time . Another reorganization on 14 April 1877 saw the number of brigades reduced to three ( of 10 batteries each ) and F Brigade was broken up . Its batteries were mostly transferred to C Brigade and redesignated again , for example , A / F Battery becoming F Battery , C Brigade . The number of brigades was further reduced to two ( of 13 batteries each ) in 1882 . The brigade system was finally abolished in 1889 . Henceforth , batteries were designated in a single alphabetical sequence in order of seniority from date of formation . VI Brigade , RHA . First formation . The brigade system was revived in 1901 . Each brigade now commanded just two batteries and a small staff ( a Lieutenant - Colonel in command , an adjutant and a brigade sergeant major ) . Initially , batteries were not assigned to brigades in any particular order , but in 1906 , at the insistence of Edward VII , brigades were redesignated so that batteries were roughly in order of seniority ( hence I Brigade commanded A Battery and B Battery ) . VI Brigade , RHA was formed on 1 March 1901 as the VII Brigade - Division , RHA with H Battery and K Battery . In 1903 it was redesignated as VII Brigade , RHA and was stationed at Meerut . On 1 October 1906 , it was redesignated as VI Brigade , RHA . By the time World War I broke out , the brigade was stationed at Trowbridge attached to 2nd Cavalry Brigade . H Battery was at Trowbridge and on 28 September was assigned to VII Brigade , RHA in 1st Cavalry Division as a permanent replacement for L Battery which had been almost destroyed at Néry . K Battery was at Christchurch and on 1 October was assigned to XV ( later IV ) Brigade , RHA in 3rd Cavalry Division . With the departure of its batteries , the brigade HQ was dissolved . Second formation . By October 1919 , VI Brigade , RHA was reformed at Shorncliffe in the United Kingdom with This new incarnation was short - lived , however . On 8 January 1920 , the Headquarters was absorbed into the HQ of 8th Brigade , Royal Field Artillery . On 4 May 1920 , V , W , and X Batteries were converted to 137th , 138th and 139th Batteries , RFA in 8th Brigade , RFA . 6th Regiment , RHA . 6th Regiment , RHA was formed on 1 November 1940 at Bulwick , Northamptonshire from a cadre of 5th Regiment , RHA . Initially , it commanded 1 , 2 and 3 batteries until they took on the identities of N , O and P batteries . In March 1941 , P Battery , RHA left 3rd Regiment , RHA and returned to the UK . In February 1942 , O Battery , RHA was unlinked from B / O Battery of 1st Regiment , RHA and returned to the UK . In April 1942 , N Battery , RHA was unlinked from I / N Battery of 2nd Regiment , RHA and returned to the UK . The regiment did not see active service in World War II , instead it remained in England as a training formation to provide officers and men to the other regiments . On 4 December 1940 it was assigned to the 9th Support Group of 9th Armoured Division and remained with the division when 9th Support Group was disbanded on 12 June 1942 . It remained under command of 9th Armoured Division until 10 July 1944 . 9th Armoured Division was disbanded shortly thereafter . In December 1945 the regiment was posted to India , the last RHA unit to serve there . On 29 April 1947 , the regiment departed Bombay ( Mumbai ) for Port Said , Egypt arriving on 8 May . It was posted to the Canal Zone , serving there until October , before moving to Palestine on internal security duties .
