 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.The brigade / regiment underwent a number of redesignations before the outbreak of Second World War.
