Before the first clash of the Northwest Rebellion, Louis Riel talked to the Metis from the territory, predicting that a peaceful resolution to the situation was impossible. He was right. The first clash was supposed to be a peaceful negotiation, but it swiftly turned violent. Two Metis were shot while there were angry exchanges. Once the two Metis were killed, both sides opened fire and a small battle began. 12 NWMP officers were killed and many others were injured. This was the beginning of the Northwest Rebellion. The NWMP retreated. Later, the government sent out more than 5000 troops to control the rebellion.
