Baron Roman Nicolaus Von Ungern-Sternberg.

There is a book in English on this raving looney:

James Palmer, The Bloody White Baron: The Extraordinary Story of the Russian Nobleman Who Became the Last Khan of Mongolia (2009). It can be had in both hardback and paperback.

History "lite", but readable.

Always enjoyed chatting with my friend's grandfather (mentioned on another thread) about how frightened his father was about the threats that he made against those supplying the "Reds". He showed me several of the broadsides that the "Whites" put up, detailing (gory detail) what would be done to "Red" sympathizers.
