How old was Sacagawea when her tribe was attacked?

Sacagawea was around 12 years old when her tribe, the Shoshone, was attacked by the Hidatsa in 1800. This event led to her capture and eventual sale to a French-Canadian trader, Toussaint Charbonneau, who later became her husband. Her experiences during this tumultuous time shaped her future role as a guide and interpreter for the Lewis and Clark expedition.
