Originally raised in 1685 under the name of "The Princess Anne of Denmark's Regiment of Dragoons," became the 4th (Queen's Own) Hussars in 1861. As heavy cavalry the regiment fought in the Peninsular War, some brilliant exploits were performed. In 1818 the regiment became Light Dragoons, and the Regiment wore scarlet uniform with straw coloured facings, the uniform afterwards being changed back to light green. During the Crimean War it took part in the famous charge of the Light Brigade, under its Colonel, Lord George Paget, who led them with a cry of "Tally ho!" as they charged the enemy's guns. When the regiment formed part of the "Army of the Indus" under Lord Keane it was nicknamed "Paget's Irregular Horse," in consequence of its loose drill, the result of long service in the field.
