White Lance, Joseph Horn Cloud, and Dewey Beard (Iron Tail) all survived (and are brothers)
There was a mix up with some ghost dancing at Wounded Knee, and the U.S 7th Cavalry massacred a load of mainly unarmed Lakota. It is also thought that amongst the injuries the cavarly suffered, a lot was by 'friendly fire'.
There's a great book called 'Bury My Heart At Wounded Knee' (by Dee Brown) that deals with all of this stuff, and it is highly recommended if you have even the slightest interest in what atrocities occurred.
Another thing is...Dewey Beard (AKA Iron Tail) lived until 1955. I will say that again - 1955. When The Busby Babes were starting to rule, and not long before l was born.
Even though l am an old git, that is just staggering.
