The 3rd Scottish Horse was formed in August 1914 at the outbreak of World War I. The 1st and 2nd Regiments appear to have been attached to the Highland Division at Bedford and West Riding Division at Doncaster for a short time.

World War I
Br-Gen Marquis of Tullibardine was assigned to command the brigade on 15 August 1914 with 1st, 2nd and 3rd Scottish Horse under command, along with the Scottish Horse Mounted Brigade Field Ambulance, RAMC. By November 1914, the brigade was in Northumberland on coast defence duties and was attached to the 63rd (2nd Northumberland) Division from January to August 1915.

Brigade Field Ambulance
The Scottish Horse Field Ambulance developed an operating car, designed by Colonel H. Wade in 1914, which enclosed an operating table, sterilisers, full kit of instruments and surgical equipment, wire netting, rope, axes and electric lighting in a Wolseley chassis. The car was used during the Gallipoli Campaign at Suvla, in the Libyan Desert (during the Senussi Campaign), and at El-Qantarah in Egypt before being attached to the Desert Mounted Corps Operating Unit in 1917. Subsequently taking part in the Southern Palestine Offensive, which culminated in the Capture of Jerusalem.

Gallipoli
On 17 August 1915, the brigade boarded SS Transylvania at Devonport and sailed to Gallipoli where it landed at Suvla on 2 September. It joined 2nd Mounted Division and remained with it until evacuated on the night of 19/20 December 1915. It left 2nd Mounted Division on 22 December. It was transported to Alexandria via Imbros (20-24 December), arriving on 28 December and went to Sidi Bishr Camp.

In late December 1915, the brigade arrived in Egypt. In February 1916, the Scottish Horse Mounted Brigade was absorbed into the 1st Dismounted Brigade (along with the Lowland Mounted Brigade ) under the command of the 52nd (Lowland) Division to defend the Suez Canal. Br-Gen Marquis of Tullibardine was assigned to command the new dismounted brigade.
