Cap Badge - 6th Inniskilling Dragoon Guards The 6th (Inniskilling) Dragoons was a cavalry regiment in the British Army, first raised in 1689. It saw service for three centuries, before being amalgamated into the 5th/6th Dragoons (later the 5th Inniskilling Dragoon Guards, then finally the 5th Royal Inniskilling Dragoon Guards) in 1922. Enniskillen Castle and the regiments raised at Enniskillen during the Williamite Wars are inextricably linked. The Inniskilling Dragoons were quartered there many times since their formation. The badge of the regiment features a depiction of the castle. Why Inniskilling and not Enniskillen? Inniskilling was the original name of the town - anglicised from Irish meaning 'Island of Kathleen'. Since then the name has changed around 20 times before finally settling on its present spelling of Enniskillen.
