After
World War I the British Empire was at the height of its world-wide power. The
rivalry between the United States and Great Britain during the 1920s and 1930s
over who would control the world’s oil supply led American strategic planners
to envision the day when America might be at war with Great Britain. War Plan
Red (“Joint Army and Navy Basic War Plan – Red”), formulated and approved in
1930 and declassified in 1974, set out America’s plan to eliminate Great
Britain as a significant economic rival. Most of America’s plans revolved
around the annexation of Canada and the islands of Jamaica, Barbados and
Bermuda. These were American imperial dreams dating to the time of the American
Revolution, when American forces were repulsed in their attempt to conquer
Canada. American attempts to annex Canada during the War of 1812 were similarly
repulsed.
Plan Red contemplated the immediate seizure of Halifax to deny the British an Atlantic port from which they could reinforce Canada. U.S. forces would then launch a three pronged attack, (1) an attack from Vermont to take Montreal and Quebec, (2) an attack from North Dakota to seize the strategic rail center at Winnipeg, splitting the country, and (3) an attack launched against the province of Ontario from Detroit and Buffalo. Mopping up on the West Coast was to include the seizure of Vancouver and Victoria. Congress appropriated money to build three secret air bases near the Canadian border to be used for surprise attacks on Canada in the event of war. Information regarding the secret air bases was accidentally leaked, and the New York Times reported the story on the front page of the May 1, 1935 issue, much to the chagrin of the Roosevelt administration.
Canada, not unaware of America’s
historical aggressive designs, had earlier developed “Defence Scheme No. 1”
which, in the event of hostilities, called for flying columns to quickly enter
American territory. These small mobile forces were to capture such cities as
Seattle, Minneapolis and Albany, and then fall back in a scorched earth retreat
that would slow down the American invaders, giving Great Britain time to
re-enforce Canada.
America had developed similar plans in
case of hostilities with other countries.
Plan Orange was to be used in case of a war with Japan (or in
conjunction with Plan Red in case of war with both Britain and Japan). Plan Black was to be used in case of war with
Germany. Plan Green was for Mexico. Plans Orange and Black were, in fact, used as
the blueprints for victory over Japan and Germany in World War II.
