I've read several books about it, & heard people tell stories told by their parents/family members. Seems like someone called it something like the battle where the girl saved her brother-can't remember for sure. Black Elk Speaks is also a good book to read about it.
   Several years ago, a friend of my family who had just had a triple bypass & didn't think he'd be around for many more years was looking for one more project which would be big. He asked me to go with him visit some guy who'd written a musical. It was pathetic & amateur, & I told him that. Then, he was approached by somebody who handed him a copy of Black Elk Speaks. My mother & I told him that was the one. Bob decided this was the right project.
