I want to know the answer to the following question:
What is one of the threats that faced them?
All the background I'm provided with is that "The latter aided in the defence of their respective territories against attacks by other European powers, Aboriginal peoples, and later American forces during the American Revolutionary War and War of 1812, as well as in the Fenian raids, Red River Rebellion, and North-West Rebellion.". Is that enough to answer the question?
