Service in the Royal Horse Guards He was commissioned into the
Royal Horse Guards with the rank of
second lieutenant on 28 December 1892, and was promoted to
lieutenant on 30 December 1893. He served in Kitchener's expedition to the Sudan, fighting at the
Siege of Khartoum and the
Battle of Atbara. He was awarded the
Distinguished Service Order (DSO) on 15 November 1898, and rose to the rank of
captain a year later, on 20 November 1899.
Second Boer War In 1900 he served as an
aide-de-camp to Brigadier-General J. F. Burn-Murdoch, in command of a brigade of the Cavalry division stationed in
Natal. In November 1900 he was given the rank of
brevet major in the
Royal Horse Guards, and asked by
Lord Kitchener, whom he had served under on the Omdurman Campaign, to raise a regiment of Scotsmen in South Africa, called
The Scottish Horse. The regiment was raised quickly and soon saw active service in the Western Transvaal. A second regiment of Scottish Horse was raised from troops recruited by
The 7th Duke of Atholl and a permanent headquarters was set up to supply both of these regiments, with Atholl in command but with subordinate commanding officers in the field in charge of each of the Regiments. This success continued until the Scottish Horse was a whole
brigade by the end of the
Second Boer War. In August 1901 Lord Tullibardine received the local rank of
lieutenant colonel in South Africa while commanding the Scottish Horse. He was
mentioned in despatches by Lord Kitchener dated 23 June 1902. Following the end of the war in June 1902, Lord Tullibardine and most of the men of the Scottish Horse left
Cape Town on the SS
Goth in early August, and arrived at
Southampton later the same month. After his return to the United Kingdom, he was on 28 September 1902 received at
Balmoral Castle by King
Edward VII, who presented him with the Insignia of a Member (4th class) of the
Royal Victorian Order (MVO) for his services in South Africa. The following year he was promoted to the substantive rank of lieutenant colonel in the Army.
First World War In the Great War Atholl commanded a Brigade of a
Yeomanry Regiment and took them to fight dismounted (without horses) in the
Dardanelles campaign against the Turks. He gained the rank of temporary
brigadier general in 1918.
Further service During the Second World War, despite being seventy years old, Atholl joined the
Home Guard and reportedly took turns as sentry officer on duty in Whitehall. He remained closely involved with the
Scottish Horse, remaining in the post of Colonel Commandant until 1919 and Honorary Colonel from 1920 until his death in 1942. He was key in establishing a
Scottish National War Memorial in
Edinburgh Castle after the First World War and his papers relating to this are retained by the
National Library of Scotland. ==Political career==
