The 14th Dragoons, known as Dormer’s Dragoons, was raised in 1715 as a cavalry regiment in the British Army to combat the first Jacobite rebellion.  They also fought in the second rebellion after which they were used to police areas of Ireland.  In 1791 the Regiment provided an escort to Her Royal Highness The Princess Royal of Prussia.

As a mark of gratitude, the Regiment was authorised to adopt the Prussian Eagle as their badge to be worn on the right-hand-side of their Tarleton helmet.  Prior to these duties the Guidon of the 14th was Crimson, they were changed to Orange.
