Template:StubSacagawea was a famous Shoshone Indian. Her date of birth and death are unknown. When Sacagawea was about twelve, she was taken captive by the Hidatsas, who sold her to the Mandans. Toussaint Charbonneau, a French Canadian trapper, purchased her from the Mandans and made her one of his wives. Charbonneau was engaged by Lewis and Clark as the interpreter for their expedition. However, Charbonneau was hired so that Sacagawea, who was probably in her late teens at the time, would also accompany the expedition. Lewis and Clark recognized that her language skills and her knowledge of country would be critical to their success.
Eight weeks before the expedition, Sacagawea gave birth to her first child, a son who she named Jean Baptiste Charbonneau, who was nicknamed "Pomp." Sacagawea, her husband, and their infant child set out with the small expedition in 1805. When Lewis set out to make contact with a Shoshone Indian tribe, from whom he hoped to obtain horses for their long trek across the mountains, Sacagawea went along as the interpreter. When they arrived at the Shoshone camp, Sacagawea found it was led by her older brother, Cameahwait, who had taken their father's place as the chief after he died. Sacagawea, who was deeply moved by this reunion, might have taken advantage of such a coincidence to stay with her people, but instead she helped the explorers get the horses they needed and then journeyed on with them and her husband to the Pacific. If it hadn't been for Sacagawea, Lewis and Clark might never have made it to the Pacific Ocean. Little is know of Sacagawea's life after the Lewis and Clark expedition. Some sources claim she died at a trading post in 1812, while some claim she passed away in the 1880s.
