Sitting Bull's Great Grandson Tells Oral History

The oral history recording I watched was a interview with Sitting Bull's great grandson (Ernie LaPointe). On this recording he tells a story his mother told him about a man named One Bull who was a secret spy. His mother and his grandmother were in a carriage traveling and this man named One Bull rode up on a horse and started to talk to the family asking how they were and making small talk. Ernie's grandmother put a shaw over her face and told him to leave and how she never wanted to ever see his face again for what he did to Sitting Bull. 

Henry Oscar One Bull was the mans full name. He would report to McLaughlin and all of Sitting Bulls activities. Giving him information through telegram and where Sitting Bull was going to go and gave him all of his plans. Sitting Bull was planing on making council with another leader and this was prohibited because of laws saying they couldn't leave there land. One Bull found out about this and rode a horse all the way to Fort Gates. By the time One Bull returned Sitting Bull was being arrested and thats why his grandmother wouldn't look at One Bulls face. 

The interview would be a great secondary source if you were going to be doing a project on Sitting Bull. There is a lot of detailed information given and historic prof to back it up. The interview I watched was only 10 minutes long but there is a whole movie that you can watch with a lot more oral interviews. I really enjoyed watching this interview and now want to what the complete edition.
