Under the 'Localisation of the Forces' scheme introduced by the
Cardwell Reforms of 1872, Militia regiments were brigaded with their local regular and
Volunteer battalions. The 1st and 3rd RSM were linked with the
31st (Huntingdonshire) and
70th (Surrey) Regiments of Foot in Sub-District No 47 (County of Surrey) with a shared depot at Kingston. The 2nd RSM was linked with the two battalions of the
2nd (Queen's Royal) Regiment of Foot in Sub-District No 48 (County of Surrey) at Guildford. A planned second militia regiment for the sub-district, to be numbered the 4th Surrey, was never raised. The militia now came under the
War Office rather than their county lords lieutenant. Around a third of the recruits and many young officers went on to join the regular army. A new
Kingston Barracks was built for the brigade depot in 1874–5; the 1st RSM moved there from Richmond before the end of 1880. The Militia Barracks built in 1854 at Guildford had proved to be unhealthy and were now too small, so the 2nd RSM transferred to the new
Stoughton Barracks built in 1876 as the depot for the Queen's. Although often referred to as brigades, the sub-districts were purely administrative organisations, but in a continuation of the Cardwell Reforms a mobilisation scheme began to appear in the
Army List from December 1875. This assigned Regular and Militia units to places in an order of battle of corps, divisions and brigades for the 'Active Army', even though these formations were entirely theoretical, with no staff or services assigned. The 1st, 2nd and 3rd RSM were assigned to 2nd Brigade of 2nd Division,
III Corps. The brigade would have mustered at
Redhill in time of war. The
Childers Reforms of 1881 took Cardwell's reforms further, with the linked Regular regiments becoming two-battalion regiments and their linked militia formally joining as sequentially numbered battalions. On 1 July the 2nd became the
Queen's (Royal West Surrey Regiment), while the 31st and 71st became the
East Surrey Regiment. At the same time the 1st and 3rd RSM became the 3rd and 4th Battalions of the East Surrey and the 2nd RSM the 3rd Bn of the Queen's. All three Surrey militia battalions were involved: • The 3rd Queen's was embodied on 4 December 1899 and volunteered for overseas service. It embarked on 20 February 1900. After two years' service guarding
lines of communication and
Prisoner-of-war camps, manning
blockhouse lines and escorting convoys, it was preparing to return home when the Boers invaded
Namaqualand in an effort to seize the copper mines. Detachments of the 3rd Queen's and
5th Royal Warwickshires, under Lt-Col Shelton of the Queen's, together with a large number of miners, both white and
Coloured, were besieged for a month at the largest mine, at
Okiep. The grateful Cape Copper Company awarded its own unofficial
Medal for the Defence of O'okiep to all the defenders, regardless of race or service. • The 3rd East Surreys was embodied on 12 May 1900 and disembodied on 19 October. It was embodied again on 6 May 1901 and volunteered for overseas service. It served in South Africa from 1 July 1901 to June 1902, being disembodied on 10 October. • The 4th East Surreys was also embodied twice, from 4 December 1899 to 12 July 1900, and then for overseas service from 24 February 1902. Although the war was coming to an end when the battalion landed in South Africa on 10 April, part of the battalion served in the Namaqualand Field Force, fighting a sharp action at
Steinkopf before relieving the 3rd Queen's at Okiep. The battalion was disembodied on 25 September 1902 ==Special Reserve==
