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. | When Sacagawea was about twelve, she was taken captive by the [[Hidatsas]], who sold her to the Mandans.
