Generally somewhere between 2500 and 5000 Warriors. The village was approx. 20,000 in number. This was the meeting of the plains indians. The Northern Cheyenne, the Souix and others were represented there. This wasn’t just the Souix at this battle.
What I'd really like to know is where was Custer's exact position when he sent Trooper Martini off with that message; "bring packs".
Kind of a clue he knew that alligators were approaching his backside?
