great photo! I have been wondering about this picture since I found it a while ago. I think it is labeled wrong.
I don´t believe this man is Sioux. From the breastplate he wears I would assume he is from the southern plains, although he has not cut his hair in Kiowa or Comanche style. Cheyenne? I also don´t believe he is a chief, because he is much too young.
It's fair to assume the photo is from the mid 60s or later; therefore he couldn't have defeated "Colonel Baker" in 1854 because he looks far too young, although he may have taken part in a major 1854 fight as a teenager or boy - the Grattan debacle? Maybe someone can date the photo from the gun he's carrying.
Unfortunately, i have only this information: Sioux Chief who defeated col. Baker in 1854. Studio portrait of a native american Sioux man,identified as Chief Running Bear.He has a blanket wrappet around his waist and shoulders,wears a long sleeve shirt,cloth bound braids,arm bands and a breastplate,and holds a rifle in his lap. Date:between 1860-1880. I ask: who was this wild and fierce man? For me,if he don't was a Chief,certainly was a great warrior!!! Looks at his face! And then: who was col. Baker? What important battle he fought in 1854? We cannot leave all that in the mistery!!!
Sorry Charlie, I haven´t found a Col. Baker in 1854, yet. There were several incidents with Maj., Lt. and Col. Bakers in U.S. history, but not in 1854. I first thought of the Grattan fight, but there is no Baker ...and no Running Bear as well.
Running Bear dove in the water, Little White Dove did the same..................
I can't find any Baker fight in 1854, which doesn't necessarily mean anything, since I don't have much of a library of that period, but I do remember passing by someplace called Baker's Battlefield, and I know it was not in Montana or Wyoming. So it was not the Eugene Baker who slaughtered the Piegans [was it 1870?]. I just can't remember where or when it was that I saw the reference.
Of course the date and particulars may be totally out of whack.
