In a bookstore last night, I picked up Scott W. Berg's 38 Nooses: Lincoln, Little Crow, and the Beginning of the Frontier's End. Published recently to good reviews, the book provides good background to my Jan. 31 post, "A gruesome death." You can read reviews of 38 Nooses here, here and here.
Adrian J. Ebell, whose newspaper story about the battle of Wood Lake is part of my post, photographed Indians in Minnesota in 1862 and later studied medicine and became a lecturer in natural science. Here and here you'll find interesting sites about Ebell and his photographs. The second of those sites has a wartime photo (CDV) of him.
