Quote from a report about Wounded Knee, which involved the 7th Cvalry, which was Custer's command in the WBTS, and thus on topic: from Captain Edwin Godfrey, Troop D, "I was posted on the side of the ravine, with the ravine between myself and the Indian village. I WAS UNDER THE COMMAND OF CAPTAIN (HENRY) JACKSON, WHOSE TROOP WAS THERE ALSO AND WHO WAS MY SENIOR. The troop was deployed with intervals, and mounted, about fifty yards behind the line of scouts."
Now you could argue the good captain was merely recognizing the chain, or that he was passing the buck, but it does go to your point. Stan
