After the death of Sitting Bull, many of the Sioux were terrified, so they fled to a creek called Wounded Knee, in South Dakota. The U.S. Army then went to Wounded Knee to collect the Sioux's weapons. When they arrived at Wounded Knee, for an unknown reason, fighting broke out. The Army heard a pistol shot and responded with gun fire. This marked the end of the fight between the whites and the Native Americans, the Native Americans had lost there long battle.
