Royal Devon Yeomanry cap badge, King's crown

The Royal Devon Yeomanry was a Yeomanry regiment of the British Army, formed in 1920. It participated in the Second World War and now forms a squadron of the Royal Wessex Yeomanry.
Following the experience of the First World War, it was decided that only the fourteen most senior yeomanry regiments would be retained as horsed cavalry, with the rest being transferred to other roles. As a result, on 7 June 1920, the Royal 1st Devon Yeomanry was amalgamated with the Royal North Devon Yeomanry to form the Royal Devon Yeomanry and simultaneously transferred to the Royal Artillery to form 11th (Devon) Army Brigade, RFA.
