The Battles of Khalkhin Gol (Russian: Бои на Халхин-Голе, romanized: Boy na Khalkhin-Gole; Mongolian: Халхын голын байлдаан, romanized: Khalkhyn golyn baildaan), known in Japan as the Nomonhan Incident (Japanese: ノモンハン事件, Hepburn: Nomonhan jiken) after Nomonhan Burd Obo, were the decisive engagements of the undeclared Soviet–Japanese border conflicts which involved the Soviet Union, Mongolia, Japan, and Manchukuo in 1939. The conflict is named after the river Khalkhin Gol, which passes through the battlefield. The Soviet offensive, led by general Georgy Zhukov, utilized airplanes, tanks, and infantry in a simultaneous three-pronged offensive, the first of its kind in modern warfare. Similar tactics were later used during Operation Uranus at the Battle of Stalingrad. The Soviet–Japanese Neutrality Pact was later signed in April 1941. The decisive Soviet victory altered the eventual course of World War II by dissuading the Empire of Japan from any further confrontation with the Soviet Union under its Hokushin-ron (strike north) doctrine.
