One of the most legendary members of the Lewis and Clark expedition was Sacagawea, a teenaged Shoshone Indian who had been kidnapped from her tribe as an adolescent. Sacagawea, her husband and her newborn son first joined up with the explorers as they wintered at a Hidatsa-Mandan settlement in 1804, and she later served as an interpreter and occasional guide on their journey to the Pacific. During a run-in with a band of Shoshone in the summer of 1805, she famously discovered the tribe’s chief was none other than her long lost brother, whom she had not seen since her abduction five years earlier. The tearful reunion helped facilitate peaceful relations between the explorers and the Shoshone, allowing Lewis to procure much-needed horses for his trek over the Rockies.
