"The U.S. Navy’s Secret, 11-Page Plan to Conquer Canada" Topic

"The U.S. Navy schemed to invade Canada during the summer of 1887. This fact may surprise readers familiar with the long history of amicable relations between the United States and its northern neighbor. Even in 1887, the United States and the British Empire (which included Canada) were on generally agreeable terms. Nevertheless, Lt. j.g. Charles C. Rogers, USN, observing that "the frontier of Canada is assailable at all points," imagined a joint Army–Navy campaign to seize Canada's strategic heartland. "The distribution of her population, and the situation of her most important cities and strategical points," he posited, "suggest three invading armies from the United States."

A dispute with Britain over fishing rights in Canadian waters prompted the Navy's strategic planning initiative in 1887. During the summer of that year, undercover agents from the recently established Office of Naval Intelligence (ONI) traveled north to examine Canadian defenses. The ONI mission coincided with another reconnaissance conducted by Rogers. Under orders from North Atlantic Squadron commander Rear Adm. Stephen B. Luce, Rogers visited strategic sites in eastern Canada. After completing his survey, Rogers compiled several classified reports at ONI headquarters in Washington, D.C. One study, entitled "Intelligence Report of the General War Resources of the Dominion of Canada" included an eleven-page "Plan of Operations" for conquering the great northland…"

Part of the Rainbow plan was a war with Britain which included an invasion of Canada (Case Red:UK was "Red", Canada "Crimson", India "Ruby", Australia "Scarlet" and New Zealand "Garnet"). I have no doubt that the British had a plan for a war with the United States. I suspect that every nations war planning organization is busy making war plans for any possible contingency. It keeps the planning organization busy and employed.

According to the public intelligence site, Global Security, the following plans are known to have existed:

War Plan Black: A plan for war with Germany. The best-known version of Black was conceived as a contingency plan during World War I, in case France fell and the Germans attempted to seize French possessions in the Caribbean Sea, or launch an attack on the eastern seaboard.

War Plan Gray: There were two War Plans named Gray. The first dealt with Central America[10] and the Caribbean, and the second dealt with invading the Portuguese Azores.[11]

War Plan Brown: Dealt with an uprising in the Philippines.

War Plan Tan: Intervention in Cuba.

War Plan Red: Plan for Great Britain (with sub variants Crimson, Scarlet, Ruby, Garnet, and Emerald for British dominions)

War Plan Orange: Plan for Japan.

War Plan Red-Orange: Considered a two-front war with the United States (Blue) opposing Japan (Orange) and the British Empire (Red) simultaneously. Ultimately this analysis led to the understanding that the United States didn't have the resources to fight a two front war, and it would make sense to focus on one front, probably in the Atlantic. Ultimately this was the decision made in the Plan Dog memo.

War Plan Yellow: Dealt with war in China—specifically, anticipating a repeat of the Boxer Uprising (1899–1901).[18] War Plan Yellow would deploy the US army in coalition with other imperial forces to suppress indigenous discontent in the Shanghai International Settlement and Beijing Legation Quarter,[19] with chemical weapons if necessary.[20]

War Plan Gold: Involved war with France, and/or France's Caribbean colonies.

War Plan Green: Involved war with Mexico or what was known as "Mexican Domestic Intervention" in order to defeat rebel forces and establish a pro-American government. War Plan Green was officially canceled in 1946.

War Plan Indigo: Involved an occupation of Iceland. In 1941, while Denmark was under German occupation, the US actually did occupy Iceland, relieving British units during the Battle of the Atlantic.

War Plan Purple: Dealt with invading a South American republic.

War Plan Violet: Covered Latin America.

War Plan White: Dealt with a domestic uprising in the US, and later evolved to Operation Garden Plot, the general US military plan for civil disturbances and peaceful protests. Parts of War Plan White were used to deal with the Bonus Expeditionary Force in 1932. Communist insurgents were considered the most likely threat by the authors of War Plan White.

War Plan Blue: Covered defensive plans and preparations that the United States should take in times of peace.

Hmmmm, perhaps someone should dust off War Plan Blue.

No surprise here.

The bigger shock may have been that Canada made some initial planning to attack the US before the first war and even in the twenties. Probably more of an organizational effort to see how planning went.

The Royal Canadian Legion magazine had a great article on it about ten years ago.

Another of the periodic attempts to make the US look bad. A couple of years ago there was a big hoohah about the Army's part of War Plan Crimson, which turns out to have been a War College exercise, relying mostly on information from the Canadian Government and the Encyclopedia Canadiana. War plans were (and are) routinely developed by all nations against all possible opponents. Development of plans against unlikely opponents are usually used as training exercises.

But why no War Plan Periwinkle? Why no war plans in muted pastels? Such tasteless barbarism must be avenged! Igor, release the maple syrup and let slip the sweet dogs of war!
The Evil Ultramind.

What about a "what if" wargame?… (smile)

I say Canada has it coming…..Justin Bieber.

And Canadians are suppose to be civilized! harumph!

War Plan Plaid: Attack everybody, launch now, let's see if they work.

War Plan Deep Purple Dark: Martian Invasion, 1938-actually put in motion but ineffective. 2nd Armored got lost on the way to Grover's Mill New Jersey.

War Plan Monaco: Called off when they realised that the paratroopers were dropping on the same day of the Grand Prix.

"Communist insurgents were considered the most likely threat by the authors of War Plan White."

How things have changed.
