Battles of Khalkhin Gol
The Battles of Khalkhin Gol (Russian: Бои на Халхин-Голе; Mongolian: Халхын голын байлдаан) were the decisive engagements of the undeclared Soviet–Japanese border conflicts involving the Soviet Union, Mongolia, Japan and Manchukuo in 1939. The conflict was named after the river Khalkhin Gol, which passes through the battlefield. In Japan, the decisive battle of the conflict is known as the Nomonhan Incident (ノモンハン事件, Nomonhan jiken) after Nomonhan, a nearby village on the border between Mongolia and Manchuria. The battles resulted in the defeat of the Japanese Sixth Army.
