The Ghost Dance, which Sitting Bull performed many various times in his life, was a very meaningful dance to the Indians.  They believed that this dance would bring back the buffalo and erase the white man from their lands.  After the Battle of Rosebud, Sitting Bull performed this mysterious, yet interesting, dance.  While unconscious, he had a vision of soldiers falling from the sky, which meant that the soldiers would return.  In a few days, this vision became a reality when they were attacked by four times the amount of soldiers that they had previously fought in a battle known as the "Battle of Little Big Horn."  The practice of the Ghost Dance later lead to the slaughter of hundreds of Indians at Wounded Knee.  Among the slaughtered were Sitting Bull's band of Sioux and Cheyenne followers.
