Russian White Guard troops led by Baron R.F. von Ungern-Sternberg (Baron Ungern von Sternberg), who had been defeated in the Civil War in Transbaikalian Siberia, invaded Mongolia in October 1920. In October–November 1920, Ungern’s troops assaulted the capital, Niislel Khuree, known to Europeans under the name Urga (now Ulaanbaatar), several times but were repelled with heavy losses. Ungern entered contacts with Mongolian nobles and lamas and received Bogd Khaan’s edict to regain independence. On 2–5 February 1921, after fighting a huge battle, he drove the Chinese forces out of Mongolian capital.
