20th (Inniskilling) Regiment of Light Dragoons

Early references to the Regiment originate from 1759, when the 20th (Inniskilling) Regiment of Light Dragoons was raised because of the expansion of the 'Light Troop' of the 6th (Inniskilling) Dragoons. For some reason not entirely clear, this first incarnation of the 20th Light Dragoons was disbanded in 1763, only to be resurrected sixteen years later in 1779.

The 20th Hussars

The 20th remained on the North West Frontier for the next seven years during which time it participated in the Umbeyla Expedition also known as the Eusocf zie Campaign, from October to December 1863 and the Hazara Campaign of October 1868, but were used only to protect the lines of communication.
