The Yeomanry was not intended to serve overseas, but due to the string of defeats during
Black Week in December 1899, the British government realised they were going to need more troops than just the regular army. A Royal Warrant was issued on 24 December 1899 to allow volunteer forces to serve in the
Second Boer War. The Royal Warrant asked standing Yeomanry
regiments to provide service
companies of approximately 115 men each for the
Imperial Yeomanry, which was equipped to operate as
Mounted infantry. The regiment provided: The Yorkshire Dragoons sponsored the
11th (Yorkshire Dragoons) Company and the Yorkshire Hussars the 9th (Yorkshire (Doncaster)) Company. An equipment and emergency fund was set up and by 2 January 1900 13th Yeomanry Brigade had enrolled 330 volunteers (180 from the Dragoons) at Leeds. Selection and mobilisation began at
Sheffield Cavalry Barracks on 6 January and the two companies were completed by 17 January. Along with two companies from
Nottinghamshire, the 9th and 11th served in the 3rd Battalion, IY, which was placed under the command of Temporary Lt-Col
George Younghusband from the
Indian Army. The Earl of Scarbrough was appointed second-in-command as a Temporary Major. 3rd Battalion with its horses embarked on at
Liverpool on 29 January and was the first IY battalion to arrive in South Africa, disembarking at
Cape Town on 20 February 1900. The Yorkshire Dragoons and Hussars also co-sponsored the
66th (Yorkshire) Company, formed in March 1900. The 66th Company arrived in South Africa on 10 April and joined in the 16th Battalion, IY, transferring to the 3rd when the 16th was broken up in 1902. The Yorkshire Dragoons later raised the
111th (Yorkshire Dragoons) Company for the Second Contingent of the IY in 1902. Boshof had been a dismounted action, but at Rooidam on 5 May the Yorkshire Dragoons seized a
kraal at a gallop, which allowed them to secure a
kopje from which they could
enfilade the Boers' main position. Methuen's Column quickly became known as the 'Mobile Marvels'. On 14 May Methuen marched on
Hoopstad and then continued into
Orange Free State protecting the flank of
Lord Roberts' main army. Methuen's column reached
Bothaville on 24 May, but Roberts became concerned about his communications, so Methuen was switched to protecting the rear, and marched to
Kroonstad, where his force arrived on 28 May, having completed a march of in 15 days over poor roads. On 30 May, Methuen was informed that the 13th (Irish) Bn IY was cut off at
Lindley, and he rode with his own IY battalions to relieve them, covering in 24 hours. The mounted column had a five-hour fight to force its way past 3000 Boers led by
Christiaan de Wet. Most of the force in Lindley had already surrendered, but Younghusband was able to free a number of the prisoners. Methuen then pushed on to relieve 9th Division, which was besieged at
Heilbron, completing a march of in under a month.
Guerrilla warfare Methuen's Column now took part in the pursuit of de Wet's force south down the railway towards Kroonstad, beginning with a sharp action at
Renoster River on 24 June. The 'Great de Wet Hunt' began in earnest in August, with Methuen personally leading a column including the 1st Yeomanry Brigade. Methuen drove his force on with little rest, to
Welverdiend Pass and Taaibosch Spruit, then to
Frederikstad. On 12 August the column engaged the Boers at Mooi River Bridge for four hours, capturing guns and wagons and freeing British prisoners. Methuen's column had covered in six days, driving de Wet towards the Olifant's Nek pass, which Methuen believed was blocked by other columns. On the night of 13/14 August his troops set out to catch the Boers, engaging them at
Buffelshoek about from the pass. However, the Boers escaped through the pass, which had not been blocked. With his troops exhausted, Methuen had to call off the pursuit. Drives to catch the remaining commandos went on for almost another two years. The First Contingent of the Imperial Yeomanry completed their year's term of service in 1901. Between 24 March 1900 and 4 April 1901 the 3rd Battalion marched and was in action 39 times, suffering 109 casualties out of a strength of 500 men. The 66th Company in 16th Bn was in 16 major actions. Lieutenant
Alexis Charles Doxat, who had gone out to South Africa in 11th Company, became reconnaissance officer to Maj-Gen
Douglas's column and won a
Victoria Cross at
Zeerust on 20 October 1900, galloping back to rescue a man who had lost his horse. Many of the Yeomanry went home after their year's service and were replaced by a Second Contingent, including the 111th (Yorkshire Dragoons) Company, which joined the 3rd Bn, while others stayed on during the gruelling last year of the war. At Middlepost on 5 February 1902 Lts Chichester and Tabor were sent up to hold a ridge with 11 men of the Yorkshire Dragoons. Both officers and five men were killed, the others wounded before they were overrun. The war ended on 31 May 1902 with the
Treaty of Vereeniging. The service of its IY companies earned the Yorkshire its first
Battle honour:
South Africa 1900–02. The Imperial Yeomanry had been trained and equipped as mounted infantry. The concept was considered a success and before the war ended the existing Yeomanry regiments at home were converted into Imperial Yeomanry, with an establishment of HQ and four squadrons with a machine gun section. This included the retitled '''Yorkshire Dragoons Imperial Yeomanry (Queen's Own)'''. , RHQ in the early 20th century ==Territorial Force==
