M Battery, Royal Horse Artillery was formed on 23 January 1809 as 2nd Troop, Madras Horse Artillery, a horse artillerybattery of the Honourable East India Company's Madras Army.[1] On 5 August 1825, it was redesignated as B Troop, 1st Brigade, Madras Horse Artillery[2] as the Madras Horse Artillery expanded to 8 troops and was organized as two brigades. A reduction to 6 troops on 4 January 1831 resulted in the brigades being discontinued and the remaining troops lettered in a single sequence, hence becoming B Troop, Madras Horse Artillery.[3]
As a result of the Indian Rebellion of 1857, 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 Madras Horse Artillery transferred to the Royal Artillery as its 3rd Horse Artillery Brigade[a] and B Troop became B Battery, 3rd Horse Brigade, RA.[2]
Late Victorian era
The battery was stationed at Secunderabad from June 1862.[5][6] A reorganization of the horse artillery on 13 April 1864 saw 3rd Brigade became D Brigade.[7][b] As battery designations were tied to the brigade the battery was assigned to, the battery was now designated B Battery, D Brigade.[2]
From 1866, the term "Royal Horse Artillery" appeared in Army List[8] hence the battery was designated B Battery, D 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 D Brigade was broken up. Its batteries were transferred to B and C Brigades and redesignated again, hence the battery became G Battery, B Brigade.[9] The number of brigades was further reduced to two (of 13 batteries each) in 1882 without effecting the designation of the battery.[10] The battery took part in the Anglo-Egyptian War, notably the Battle of Tel el-Kebir in September 1882.[6]
The brigade system was finally abolished on 1 July 1889. Henceforth, batteries were designated in a single alphabetical sequence in order of seniority from date of formation[11] and the battery took on its final designation as M Battery, Royal Horse Artillery.[2]
The brigade system was reintroduced on 1 March 1901, this time as tactical formations, and the battery was assigned to the XIV Brigade-Division, RHA (redesignated as VIII Brigade, RHA on 1 October 1906) along with Q Battery[16] and was stationed at Woolwich.[17]
In the aftermath of the First World War, the Royal Horse Artillery was reorganized as it returned to pre-war levels and the battery was assigned to I Brigade, RHA. Further reductions saw the RHA shrink to five brigades (of three batteries each) by March 1920;[27]VIII Brigade, RHA was absorbed in I Brigade[16] and, in particular, M Battery absorbed AA Battery[f] on 4 January 1920 (the batteries were separated again on 11 May 1938).[2][28]
By March 1920, the battery was overseas again, in Egypt.[30] In October 1923 it returned to the United Kingdom and was stationed at Exeter.[31] In November 1926 it moved to Aldershot where it was transferred to III Brigade, RHA.[32] 1934 saw the start of mechanization; M and A Batteries were the first RHA batteries to be converted, replacing their horses and 13 pounders with 3.7" Howitzers towed by Light Dragon gun tractors.[33] In September 1937 it moved back to Egypt with the brigade and was at Abbassia.[32]
Two significant changes occurred in 1938. Firstly, artillery brigades were reorganized from three six-gun batteries to two 12-gun batteries. Rather than disband existing batteries, they were instead linked in pairs. As a result, M Battery was linked with P Battery to form M/P Battery on 11 May.[2] The second change was that hereafter brigades were redesignated as regiments and III Brigade became 3rd Regiment Royal Horse Artillery on 27 August with D/J and M/P Batteries.[32] In the event, the batteries were unlinked within months (in September 1939) and the regiment operated with four batteries (D, J, M and P).[34]
Second World War
By the outbreak of the Second World War, 3rd Regiment, RHA was still in Egypt and on 16 October 1939 was assigned to Headquarters RA Group (Middle East Reserve).[35] M Battery, however, was permanently attached to the Armoured Division (Egypt) (later the 7th Armoured Division, the "Desert Rats") in the anti-tank role[36] armed with 2 pounder guns.[37] The battery was to remain with the 7th Armoured Division for the rest of the war.[36]
The regiment left the 7th Support Group on 8 February 1942 (the day before it was reformed as the 7th Motor Brigade)[38] and was assigned directly to the 7th Armoured Division.[36]
^The original Horse Brigade Royal Artillery formed 1st Horse Brigade RA, the 1st Brigade Bengal Horse Artillery became 2nd Horse Brigade RA, the Madras Horse Artillery became 3rd Horse Brigade RA, the Bombay Horse Artillery became 4th Horse Brigade RA and the 2nd Brigade Bengal Horse Artillery became 5th Horse Brigade RA. The 3rd Brigade Bengal Horse Artillery was split between 2nd and 5th Horse Brigades RA. These brigades performed an administrative, rather than tactical, role.[4]
^The 1st Brigade with 10 batteries was much larger than the other four (with four to seven batteries each) so was split as A and B Brigades, 2nd Brigade become C Brigade, 3rd become D Brigade, 4th become E Brigade, and 5th become F Brigade.[7]
^A Subsection consisted of a single gun and limber drawn by six horses (with three drivers), eight gunners (riding on the limber or mounted on their own horses), and an ammunition wagon also drawn by six horses (with three drivers).[24] Two Subsections formed a Section and in a six gun battery these would be designated as Left, Centre and Right Sections.[13]
^From 1 July 1889, RHA batteries were lettered in a single alphabetical sequence in order of seniority from date of formation.[11] When more than 26 batteries were needed, double letters were used, AA,[28]BB,[29] etc.
