In 2004, in Russia, the publishing house "KMK Scientific Publications Partnership" published the book "The Legendary Baron: Unknown Pages of the Civil War".
In fact, this book contains the memoirs of two officers:
N.N. Knyazev "The Legendary Baron" and M.G. Tornovsky "Events in Mongolia - Khalkha in 1920-1921. Military - historical essay (memories)".
I know of this book only in an electronic copy of poor quality. The information is quite interesting, including maps of military operations and lists of troop composition.
There are photographs, but they are of poor quality (although most of them can be found in good quality from other sources - their annotations in this book are valuable).
Here is a digital Internet copy, but I am not ready to say whether it is complete. But the photographs are present.
