While in Montana, Lewis and the expedition spot eight Blackfeet warriors approaching, riding on horseback. The hostility flares went up and then back down when the warriors saw that the Corps was not aggressive. Lewis then let them stay with the Expedition that night. After a while of negotiations, the warriors soon realized that the Corps had been making peace and contracts with their enemies; the Shoshone and Nez Perce. A fight came, and men from the expedition killed three of the warriors.
