Originally raised in 1697 and disbanded. Again raised in 1715. It fought with distinction through the whole of the Peninsular War from first to last, and was engaged times without number. In the pursuit after the battle of Vittoria, the 14th came up with Joseph Buonaparte's carriage, from which he had but just escaped, leaving behind him a celebrated but indescribable silver trophy called The Emperor's Chambermaid, still widely renowned throughout the service. This is the corps of Charles O'Malley's choice, and mustered in its ranks the ever memorable Micky Free. In 1848 the regiment charged vastly superior numbers of the Sikh army at the battle of Ramnuggar, losing their Brigadier, their Colonel, and 40 officers and men, and have since been known as the Ramnuggar Boys—the anniversary of that battle being still observed as a great day in the regiment. It fought in Persia in 1857, and was particularly distinguished in Central India.

Nicknamed "The Emperor's Chambermaids."
