Establishment of the First Canadian Army in April 1942 led to a tremendous demand for intelligence specialists, and on 29 October 1942 the Canadian Intelligence Corps (C Int C) was officially recognized as a corps. Canadians from universities, colleges, businesses and industries joined the C Int C to participate in a great variety of intelligence duties; a number became casualties at the Dieppe Raid, in Northwest Europe and the Adriatic. Army Intelligence sections or staffs were represented at army, corps, division, and district levels, with seven field security sections in existence as well. By 1943, for the first time in Canadian history, Canadian personnel filled all intelligence appointments within Canada's Army formations and units.
