Mikhail Matiyasevich

From the nobility of the Smolensk province, he fought in the Russo-Japanese War, as a lieutenant in the 220th Infantry Regiment.

In February of 1918 he was demobilized and apparently for ideological reasons, he voluntarily joined the Red Army in April 1918.

He fought in the Russian civil war of 1918–1920 initially at the head of the 1st Smolensk Infantry Division, and then as commander of the right group of the 5th Army around Kazan.

From February 8, 1920, to August 29, 1921, he was commander of the East Siberian Military District and the 5th Army, which destroyed the remains of Kolchak's troops, as well as the Asian division of Roman von Ungern-Sternberg.

After the War, he lectured at several schools, including the Taras Shevchenko National University of Kyiv, until he was arrested in 1931.
