Lieutenant-Colonel Victor Brereton Rivers, a former officer cadet at the Royal Military College of Canada was one of the first of a small band of Canadian military intelligence officers serving in an organization that was in effect the forerunner of Canadian Forces Intelligence Branch as it is known today. He carried out the necessary staff work which led to the formation of the "Canadian Corps of Guides" (C of G) as authorized by "General Order 61 of 01 April 1903." This order directed that at each of the 12 military districts across Canada there would be a district intelligence officer (DIO) whose duties included command of the C of G in his district.
