Big Foot and around 350 Lakota Sioux, including many women and children, were surrounded by the US Army at Wounded Knee Creek in South Dakota in December 1890. A medicine man performed a sacred dance for the tribe. Tensions escalated when a deaf tribesman struggled to relinquish his weapon, and shots were fired by both sides. Over 150 Lakota men, women, and children were killed by the Army in the Wounded Knee Massacre, one of the final major conflicts of the American Indian Wars. Big Foot died along with many others, as the Army also suffered casualties from friendly fire.
