Fred Hans, as a scout, was selected by Gen. Phil H. Sheridan in the early 1880s to investigate the circumstances leading to Custer's Last Stand. Would you happen to have any records or info of the results of that investigation ?
Fred Hans wrote a book titled "The Great Sioux Nation" published in 1907. It has been digitized by Google and can be read on-line. Fred also kept a diary that was published by the South Dakota Historical Society--"Scouting for the US Army 1876-1879 the diary of Fred M Hans"
Can you look for the name of Fred Hans (scout) in the book you mention
