The 5th Middlesex Militia or Royal Elthorne Light Infantry was an auxiliary regiment raised in Middlesex in the Home counties of England just before the Crimean War. It later became part of the Middlesex Regiment. Primarily intended for home defence, it served in England and Ireland during Britain's major wars, and saw active service during the Second Boer War. It was converted to the Special Reserve under the Haldane Reforms and supplied reinforcements to the Royal Fusiliers' fighting battalions during World War I. After a shadowy postwar existence the unit was finally disbanded in 1953.

Background

The universal obligation to military service in the Shire levy was long established in England and its legal basis was updated by two acts of 1557 (4 & 5 Ph. & M. cc. 2 and 3), which placed selected men, the 'trained bands', under the command of Lords Lieutenant appointed by the monarch. This is seen as the starting date for the organised county militia in England. It was an important element in the country's defence at the time of the Spanish Armada in the 1580s, and control of the militia was one of the areas of dispute between King Charles I and Parliament that led to the English Civil War. The English Militia was re-established under local control in 1662 after the Restoration of the monarchy, but between periods of national emergency the militia was regularly allowed to decline.Fortescue, Vol I, pp. 12, 125, 133–40, 194–7, 294–5.Grierson, pp. 6–7.Hay, pp. 11–17, 25–6.

Under threat of French invasion during the Seven Years' War a series of Militia Acts from 1757 reorganised the county militia regiments, the men being conscripted by means of parish ballots (paid substitutes were permitted) to serve for three years. Middlesex was given a quota of three regiments to raise, but failed to do so until the war was nearly over. In peacetime the militia assembled for 28 days' annual training. The Middlesex Militia were first 'embodied' for permanent service in home defence in 1778 during the War of American Independence, and served throughout the French Revolutionary and Napoleonic Wars.Fortescue, Vol II, pp. 299–302, 521.Fortescue, Vol III, pp. 173–4, 530–1.Hay, pp. 138–44, 242–3.Holmes, pp. 94–100.Knight, pp. 78–9, 111, 255.Western, p. 251.Western, Appendices A & B.

In 1797 an additional ballot was carried out to raise men for the 'Supplementary Militia' to be trained in their spare time, to reinforce the standing militia regiments if required and to form additional temporary regiments. Middlesex had to find an additional 5280 militiamen and form two new regiments, but when the first training of the Middlesex Supplementary Militia was held, very few men appeared. One of the new regiments may have been numbered the 5th Middlesex Militia but if it was ever formed it had disappeared by 1799.Hay, pp. 150–2.Western, pp. 220–3, 281–3.

During the French wars, the militia were embodied for a whole generation, and became regiments of full-time professional soldiers (though restricted to service in the British Isles), which the Regular Army increasingly saw as a prime source of recruits. They served in coast defences, manning garrisons, guarding prisoners of war, for internal security, and later for limited overseas service, primarily for garrison duties in Europe. However, after the Battle of Waterloo the militia were disembodied and once again was allowed to decline in the years of the long peace that followed.Knight, pp. 411, 437–47.

Royal Elthorne Militia The Militia of the United Kingdom was revived by the Militia Act 1852, enacted during a period of international tension. As before, units were raised and administered on a county basis, and filled by voluntary enlistment (although conscription by means of the militia ballot might be used if the counties failed to meet their quotas). Training was for 56 days on enlistment, then for 21–28 days per year, during which the men received full army pay. Under the Act, militia units could be embodied by Royal Proclamation for full-time service in three circumstances:Dunlop, pp. 42–52.Grierson, pp. 27–9.Hay, pp. 155–7.Spiers, Army & Society, pp. 91–2. 'Whenever a state of war exists between Her Majesty and any foreign power'. 'In all cases of invasion or upon imminent danger thereof'. 'In all cases of rebellion or insurrection'.

The following year the Middlesex Militia was expanded from three to five regiments. The recruiting area of the 2nd Royal West Middlesex Militia was effectively split, with the new 5th Regiment taking over the north-western part of the county in Elthorne Hundred (one of the ancient subdivisions of the County of Middlesex, centred on Uxbridge and roughly coinciding with the modern London Borough of Hillingdon) while the existing 2nd regiment took over Edmonton Hundred, the most northerly division of Middlesex, then centred on Barnet. The existing regiment was therefore redesignated the '2nd or Edmonton Royal Rifle Regiment of Middlesex Militia', and the new regiment was the 5th or Royal Elthorne Regiment of Middlesex Militia raised on 16 May 1853 at Uxbridge under Lieutenant-Colonel Commandant Hon Frederick Child Villiers, a former captain in the Coldstream Guards and lieutenant-colonel in the 73rd (Perthshire) Regiment of Foot.London Gazette, 20 May 1853.Hart's, 1855.Parkyn.Hay, pp. 382–3.Frederick, pp. 212–5.Burke's: 'Jersey'. All of the regiment's majors and captains had previous experience in the Regular Army.

The 4th Middlesex Militia (the Royal South Middlesex) was formed the same month, giving Middlesex a total of five regiments:Money Barnes, Appendix II.Frederick, p. 164. 1st or Royal East Middlesex Militia 2nd Middlesex, or Edmonton Royal Rifle Regiment 3rd Middlesex, or Royal Westminster Light Infantry 4th or Royal South Middlesex Militia 5th Middlesex, or Royal Elthorne Light Infantry Militia

Crimean War and Indian Mutiny War having broken out with Russia in 1854 and an expeditionary force sent to the Crimea, the militia began to be called out for home defence. The Royal Elthorne LI was embodied on 5 February 1855 at Uxbridge.Edinburgh Gazette, 6 March 1855. Villiers resigned the command and the senior major, Lodge Murray Prior, formerly of the 12th Lancers, was promoted to Lt-Col Commandant on 4 May.Army List, various dates.London Gazette, 11 May 1855.

By November the regiment had joined the Royal East Middlesex Militia at Aldershot Camp, where the huts were only just completed. During the early part of 1856 the militia regiments concentrated at Aldershot carried out collective training, and were reviewed by Queen Victoria. The war ended when the Treaty of Paris was signed on 30 March: the concentration at Aldershot was broken up in June and regiments returned to their headquarters. The Royal Elthorne LI was disembodied on 12 June 1856.Edinburgh Gazette, 6 November 1855.Davis, pp. 257–65.

A number of militia regiments were also called out to relieve regular troops required for India during the Indian Mutiny, and the Royal Elthorne LI was embodied on 1 October 1857. By the beginning of December the regiment was at Cork in Ireland.Edinburgh Gazette, 4 December 1857. In July 1858 it had moved to The Curragh outside Dublin,Edinburgh Gazette, 5 July 1859. where it remained until the end of the year when it moved into DublinEdinburgh Gazette, 4 January 1859. and then to Kilkenny before the end of January 1859.Edinburgh Gazette, 1 February 1859. It returned to Dublin in June. The regiment left Ireland for Aldershot during November 1859,Edinburgh Gazette, 6 December 1859. where it remainedEdinburgh Gazette, 6 March 1860. until it was disembodied on 31 March 1860.

Thereafter the militia regiments were called out for their annual training. The Militia Reserve introduced in 1867 consisted of present and former militiamen who undertook to serve overseas in case of war.Grierson, p. 29.

In September 1871 the British Army held Autumn Manoeuvres for the first time. 3rd Division was made up of militia regiments, the 5th Middlesex under Lt-Col John Hunter (promoted to the command on 13 February 1869) serving in 2nd Brigade along with the 1st and 2nd Royal Surrey Militia (the 1st and 2nd Middlesex were in 1st Brigade, the 3rd in 3rd Brigade). The regiments camped in the Aldershot area and were exercised round Frensham and Chobham Commons.Davis, pp. 288–91.

Cardwell Reforms Under the 'Localisation of the Forces' scheme introduced by the Cardwell Reforms of 1872, the militia were brigaded with their local Regular and Volunteer battalions. For the 5th Middlesex this was in Sub-District No 50 (Middlesex & Metropolitan) in Home District, grouped with the 57th Foot and the 77th Foot, together with the Royal East Middlesex Militia and several Rifle Volunteer Corps. The militia now came under the War Office rather than their county lords lieutenant and battalions had a large cadre of permanent staff (about 30). Around a third of the recruits and many young officers went on to join the Regular Army.Spiers, Army & Society, pp. 195–6.Spiers, Late Victorian Army, pp. 4, 15, 19.Spiers, Late Victorian Army, pp. 126–7.

Following the Cardwell Reforms a mobilisation scheme began to appear in the Army List from December 1875. This assigned places in an order of battle to Militia units serving Regular units in an 'Active Army' and a 'Garrison Army'. The 5th Middlesex Militia's assigned war station was with the Garrison Army in the Sheerness Division of the Thames and Medway defences.

The sub-districts were intended to establish a brigade depot for their linked battalions: by 1877 Sub-District No 50 had still not done so at its intended site at Hounslow Barracks. Instead the regulars used Woolwich while the militia used Warley Barracks in Essex, the 5th Middlesex retaining its regimental HQ at Uxbridge. However, by 1880 all the linked battalions had moved into Hounslow Barracks, which was shared with the Royal Fusiliers.

Middlesex Regiment

The Childers Reforms took Cardwell's reforms further, with the linked battalions forming single regiments. From 1 July 1881 the 57th and 77th Regiments became the 1st and 2nd Battalions of the Duke of Cambridge's Own (Middlesex Regiment), with the 5th Middlesex Militia becoming the 3rd (Royal Elthorne Militia) Battalion (at the same time the 1st or Royal East Middlesex Militia became the 4th Bn).Money Barnes, pp. 199–200. In 1904 the Middlesex Regiment established its own regimental depot at Mill Hill Barracks,

During the late 1890s several regiments recruiting from large conurbations, including the Middlesex Regiment in the London suburbs, were increased from two to four battalions. When the new 3rd and 4th regular battalions for the Middlesex were authorised in March 1900 the militia battalions were renumbered accordingly, with the 3rd becoming the 5th (Royal Elthorne Militia) Battalion.

Second Boer War After the disasters of Black Week at the start of the Second Boer War in December 1899, most of the regular army was sent to South Africa, the militia reserve was called out to reinforce them, and many militia units were embodied to replace them for home defence and to garrison certain overseas stations.Spiers, Army and Society, p. 239. The 5th Bn Middlesex was embodied from 4 May to 15 October 1900.

However, the war dragged on and reinforcements were needed. The 5th Middlesex was
