Joseph A. Altsheler 
The Great Sioux Trail (Illustrated) [EPUB ebook] 

‚The Great Sioux Trail‘ by Joseph A. Altsheler is the first of a group of romances concerned with the opening of the Great West just after the Civil War, and having a solid historical basis. They will be connected by the presence of leading characters in all the volumes, but every one will be in itself a complete story.
The story is set in the war time and after war period. The trial of Sioux passes through many ups and downs before the final verdict. The plot is highly compelling and it keeps the readers rivetted to the book. The element of interest is very much there till the very last line.
