When did sacajaweas husband die?

After the expedition, William Clark offered Toussaint and his family a place in St. Louis and a proper education for Jean-Baptiste (at a time where there was no opportunity for Native Americans to receive an education). He then took a job with the Missouri Fur Company, and stayed at Fort Manuel Lisa in present-day North Dakota. Evidence suggests that, while Charbonneau was on an expedition with the company in 1812, Sacagawea died at the fort. The following year Charbonneau signed over formal custody of his son and his daughter Lisette to William Clark. During the period of 1811-38, Charbonneau also worked for the Upper Missouri Agency's Indian Bureau as a translator. He may have gained this position by the patronage of William Clark, who was the governor of the Missouri Territory. He is said to have died at Fort Mandan.
