 We don't know how much of a choice she had in taking part in this expedition. She had been kidnapped at a young age. She had been married off to a white man. She had had children with him. And he told her she was going on the expedition because he had been hired by the expedition. So whether or not Sacagawea felt any sort of sense of participation or pride in going along with the Lewis and Clark expedition, we can never really know.
