among the first to enter Rome. Canada was the only country of the Americas to be actively involved in the war prior to the attack on Pearl Harbor. Canadian support for the war was mobilized through a propaganda campaign, including If Day, a staged 'Nazi' invasion of Winnipeg which generated more than $3 million in war bonds. Early campaigns Although it regularly consulted with Canada, Britain was essentially in charge of both countries' war plans during the first nine months of the war. Neither nation seriously planned for Canada's own defence; Canada's training, production, and equipment emphasized combat in Europe. Its primary role was to supply food, raw materials, and to train pilots from throughout the Empire with the British Commonwealth Air Training Plan the British proposed on 26 September 1939, not send hundreds of thousands of troops overseas as it had done in World War I. It is possible that Britain did not want Canada to send troops overseas at all. The Canadian government agreed, because doing so might result in the need for conscription, and it did not want a recurrence of the problem with French Canadians that caused the 1917 crisis. Public opinion did cause King to send the 1st Canadian Infantry Division in late 1939, possibly against British wishes, but it is possible that had the air training proposal arrived ten days earlier no Canadian troops would have left North America that year. Canada fully cooperated with Britain otherwise, devoting 90% of the manpower of the small Royal Canadian Air Force (RCAF) to the British Commonwealth Air Training Plan; a force that had trained 125 pilots annually when the war began now produced 1,460 airmen every four weeks under the plan, the largest air force training program in history. 131,553 air force personnel, including 49,808 pilots, were trained at airbases in Canada from October 1940 to March 1945. More than half of the BCAT graduates were Canadians who went on to serve with the RCAF and Royal Air Force (RAF). One out of the six RAF Bomber Command groups flying in Europe was Canadian. In 1937 the two nations had agreed that any Canadian military equipment manufactured in Canada would use British designs. While this reasonably assumed that its troops would presumably always fight with Britain so the two forces should share equipment, it also resulted in Canada being dependent on components from a source across
