　During the Japanese military expedition to Siberia, in November 1919, the Hosono Detachment of the Japanese Army engaged in battle with the Polesheviki Red Army in the northern highlands of Siberia. The Polesheviki Red Army of Russia retreated, leaving the bodies of their comrades behind. The Japanese and the Polesheviki Red Army engaged in close combat at close range, with machine guns firing at a range of less than 100 meters and grenades exploding from the outset.

　　From September 1919, Japanese regiments engaged in combat with the Russian Polesheviki Red Army. In late September, the fierce Battle of Bakhtuyskaya broke out. When the Bolshevik Red Army was at a disadvantage, they would retreat into the forest and then suddenly attack the Japanese troops with their weapons. In the Battle of Bakhtuyskaya, three Japanese officers and about 46 non-commissioned officers were killed in action.

　　In October 1917, at the end of World War I, a revolution broke out in Russia, and the world's first socialist government was born. The Allied Powers were quick to intervene militarily. Japan sent a large military force to not only China, but also to Siberia and the Maritime Province. The Japanese military expedition to Siberia supported the White Russian Army, which was opposing the Bolshevik Red Army during the Russian Civil War, from January 12, 1918 to June 24, 1922. 1,399 Japanese soldiers died, and a further 1,717 died of disease. The Bolshevik Red Army suffered 2,887 deaths and 1,421 injuries. The Japanese Army, isolated in the frozen Siberian tundra, suffered a painful retreat from Russia.
