** No one knows who killed Custer but he might have been shot crossing the Little Big Horn before the route up Last Stand Hill.**
I read that years ago in a book titled CUSTER’S FALL.
“Bury My Heart At Wounded Knee” was an excellent book. So was “The First Hundred Years Of Nino Cochise.”
I have others, but they are buried in storage. One was about Crazy Horse from one of his descendants...last name of Mitchell, I believe.
(My mind, these days, likes to go walkabout at the worst times....)
