Egham & Godley Volunteers (40 troopers) were still effective. 19th Century The Volunteers were stood down in 1814, while some of the Yeomanry continued for internal security in the years after Waterloo. The Surrey Yeomanry and the London and Westminster Light Horse provided pickets on Westminster Bridge during crowd trouble in support of Queen Caroline when she was excluded from George IV's coronation in 1820. However, by 1824 all but four troops had disappeared in Surrey, and the whole regiment was disbanded in 1828. A new Corps of Surrey Yeomanry was raised at Clapham on 12 December 1831 becoming the Surrey Regiment of Yeomanry Cavalry in 1832. However, this too was finally disbanded in 1848. During the enthusiasm for the Rifle Volunteer Movement in the 1860s, a 1st Surrey Mounted Rifle Volunteer Corps was formed at Clapham on 2 April 1860, chiefly composed of foxhunters. It was redesignated the 1st Surrey Light Horse Volunteer Corps in February 1861, but although it held a fundraising Grand Ball in February 1867, it disbanded in 1868. Imperial Yeomanry Following a string of defeats during Black Week in early December 1899, the British government realised that it would need more troops than just the regular army to fight the Second Boer War, especially mounted troops. The Imperial Yeomanry (IY) was accordingly organised as county service companies of volunteers, recruited both from the Yeomanry and from civilians, and was equipped to operate as Mounted infantry. While no Surrey units were formed, a number of returning IY veterans formed a permanent regiment in the county on 30 April 1901, which was granted the title Surrey Imperial Yeomanry (The Princess of Wales's) in June 1902. (It changed the subtitle to (Queen Mary's Regiment) after the accession of the Prince and Princess of Wales as King George V and Queen Mary in 1910.) Recruiting from London and Surrey, it was organised as follows: Regimental Headquarters (RHQ) at Clapham Park A Squadron at Pimlico B Squadron at Guildford C Squadron at Epsom D Squadron at Wimbledon Territorial Force The Imperial Yeomanry were subsumed into the new Territorial Force (TF) under the Haldane Reforms of 1908. Like the other yeomanry regiments the 'Imperial' part of the title was dropped, and the Surrey Yeomanry (QMR) was organised as follows: RHQ at Melbourne House, 73 King's Avenue, Clapham Park A Squadron at Clapham Park, with a detachment at Aldershot B Squadron at
