Despite some notable early victories at Duck Lake, Fish Creek and Cut Knife, the rebellion ended when the Métis were defeated at the Siege of Batoche. The remaining Aboriginal allies scattered. Riel was captured and put on trial. He was convicted of treason and despite many pleas across Canada for amnesty, he was hanged. Riel became a heroic martyr to Francophone Canada, and ethnic tensions escalated into a major national division whose repercussions continue to be felt. Due to the key role that the Canadian Pacific Railway played in transporting troops, Conservative political support for it increased and Parliament authorized funds to complete the country’s first transcontinental railway. Although only a few hundred people were directly affected in Saskatchewan, the rebellion’s lack of success contributed to the eventual assurance that the Prairie Provinces would be controlled by English speakers with a very limited francophone presence, and to the alienation French speakers across Canada who were embittered by the repression of their countrymen.
