On December 15th, 1890, the sun had not yet risen over Standing Rock, one of the largest Indian reservations in the United States. Snow covered the mountains and the plain, burying the tipis. The snow was immaculate and crunched under the footsteps of the approaching men. They were Lakota Indians, part of the Indian police. There were about forty of them who gradually surrounded the tepee of one of the chiefs who was also one of the most famous Indians in America. His name was Sitting Bull.
