Cameahwait
Cameahwait was the chief of the Lemhi Shoshone and Sacagawea's brother, making their reunion at the headwaters of the Missouri River in August 1805 one of the most dramatic moments of the Lewis and Clark Expedition. Upon recognizing each other, Sacagawea reportedly ran to embrace him, weeping with joy. Cameahwait provided the expedition with essential horses needed to cross the Bitterroot Mountains and shared critical geographical knowledge about the route ahead. Without his cooperation, the expedition might not have successfully crossed the Continental Divide.
Biography
Cameahwait was the chief of the Lemhi Shoshone band and, as the expedition dramatically discovered, the brother of Sacagawea. His cooperation in providing horses to the expedition was one of the most critical moments of the entire journey.
When Lewis crossed the Continental Divide at Lemhi Pass in August 1805, he encountered Cameahwait’s band — the first Shoshone the expedition met. Negotiations for horses were difficult at first, with Cameahwait suspicious of the strangers’ intentions.
Everything changed when Sacagawea was brought in to interpret and recognized Cameahwait as her brother. The emotional reunion transformed the diplomatic situation. Cameahwait agreed to provide the horses the expedition desperately needed and shared crucial geographic intelligence about the route ahead.
Cameahwait died around 1812. His decision to help the expedition — influenced by the extraordinary coincidence of his sister’s presence — was arguably the single most important act of Native cooperation during the entire journey.
