U.S. plans to invade Canada after the First World War? This is one of the most bizarre stories Ive come across on the Internet, and the most bizarre part is that its true. The U.S. military really did develop a "Joint Army and Navy Basic War Plan--Red" in the 1920s and 30s, and it really did include provisions for an invasion of Canada by the United States. The document was declassified in 1974, so this isnt really a new story, but there has been some hoopla about it lately. Concerns in some quarters notwithstanding, the whole thing was just a theoretical exercise in military planning. The brass would have made better use of their resources planning for a war with Germany, but that wasnt politically expedient. They reasoned that planning for unlikely wars was better than no planning at all. War Plan Red was never intended to be put into action except in the event of a war with the United Kingdom, an eventuality that everyone would agree was highly unlikely after about 1900. In the color codes used at that time, "Red" referred not to Canada (that was "Crimson"), but to the United Kingdom. The proposed invasion of Canada wasnt an end in itself; it was just the easiest way to hurt the U.K. The plan called for quickly seizing the key port of Halifax to prevent British resupply; cutting communication between eastern and western Canada by capturing Winnipeg; securing bridgeheads near Buffalo, Detroit, and Sault Ste. Marie; and attacking Quebec overland from New England. If everything went according to plan, the U.S. military hoped to take the Great Lakes region and St. Lawrence valley before moving on the prairies and British Columbia. Later when U.S. naval forces were built up, they might be able to take Bermuda and Britains Caribbean possessions on the road toward victory.
