I ran across an evocative phrase in a song. "Custer's Ghost" sung by Dave Stamey.

Libby's Gone
Like the Buffalo
Like the Eagle Bone Whistles of the Sioux
I remember running across information that the Sioux blew eagle bone whistles in battle.
When I listen to that song and especially that phrase, I can hear the piercing whistles above the noise and dust of the Little Bighorn.
Below is a picture of an eagle bone whistle.
