I read the spread in National Geographic a few years abck and the Discovery Channel (?) special on it. Plus there was a true forensic investigation (Smithsonian?) that followed the soldiers’ and armed Lakota positions, via shell casings’ markings. They concluded that from the start to finish of “The Battle” probably didn’t take more than 30 minutes.........
Too bad, because the latest National Park Service researchs found that 200 Indians were killed on the battlefield alone.
The battle, according to recent studies, lasted from 2 to 4 hours.
