In the last military engagement fought on Canadian soil, the Cree leader, Big Bear, escapes the North-West Mounted Police.

The Cree are a North American Indigenous people, numbering more than 350,000 in Canada, where they form one of the country's largest First Nations macro-communities. There are numerous Cree peoples and several nations closely related to the Cree, these being the: Plains Cree, Woodland Cree, Rocky Cree, Swampy Cree, Moose Cree, and East Cree with the Atikamekw, Innu, and Naskapi being closely related. Also closely related to the Cree are the Oji-Cree and Métis, both nations of mixed heritage, the former with Ojibweg and the latter with European fur traders. Cree homelands account for a majority of eastern and central Canada, from Eeyou Istchee in the East in what is now Quebec to northern Ontario, much of the Canadian prairies, and up into British Columbia and the Northwest Territories. Although a majority of Cree live in Canada, there are small communities in the United States, living mostly in Montana where they share Rocky Boy's Indian Reservation with the Ojibwe (Chippewa) people.

Big Bear, also known as Mistahi-maskwa, was a powerful and popular Cree chief who played many pivotal roles in Canadian history. He was appointed to chief of his band at the age of 40 upon the death of his father, Black Powder, under his father's harmonious and inclusive rule which directly impacted his own leadership. Big Bear is most notable for his involvement in Treaty 6 and the 1885 North-West Rebellion; he was one of the few chief leaders who objected to the signing of the treaty with the Canadian government. He felt that signing the treaty would ultimately have devastating effects on his nation as well as other Indigenous nations. This included losing the free nomadic lifestyle that his nation and others were accustomed to. Big Bear also took part in one of the last major battles between the Cree and the Blackfoot nations, leading fighters in the last, largest battle on the Canadian Plains.

The North-West Mounted Police (NWMP) was a Canadian paramilitary police force, established in 1873, to maintain order in the new Canadian North-West Territories (NWT) following the 1870 transfer of Rupert's Land and North-Western Territory to Canada from the Hudson's Bay Company, the Red River Rebellion and in response to lawlessness, demonstrated by the subsequent Cypress Hills Massacre and fears of United States military intervention. The NWMP combined military, police and judicial functions along similar lines to the Royal Irish Constabulary. A small, mobile police force was chosen to reduce potential for tensions with the United States and First Nations. The NWMP uniforms included red coats deliberately reminiscent of British and Canadian military uniforms.
