Question: What was known as anti-Bolshevik lieutenant general and fought against the 36th Rifle Division in campaign?
Context: The 20th Rifle Division was an infantry division of the Soviet Red Army, formed three times.  The first formation of the division lasted from 1919 to 1921 and fought during the Russian Civil War before its downsizing into a brigade.  The brigade became the 3rd Rifle Division, the Caucasian Mountain Rifle Division, and the 20th Mountain Rifle Division during the interwar years.  In 1944 the 20th became the 20th Rifle Division again.  It was disbanded after the end of the war.  The division briefly reformed between 1955 and 1957 from the 188th Rifle Division and was converted into a motor rifle division. The 79th traces its history back to the formation of the Sakhalin Rifle Division on 17 August 1938.  In January 1939, the division became the 79th Mountain Rifle Division, commanded by Kombrig Ivan Makarenko.  In 1940, it was converted into the 79th Rifle Division.  It became part of the 16th Army's 56th Rifle Corps in 1943.  During August and September 1945, the division fought in the Invasion of South Sakhalin.  For its actions in the invasion, the division was awarded the honorific "Sakhalin".  During the battle for south Sakhalin, 179th Rifle Regiment Battalion commander Captain Leonid Smirnykh was posthumously awarded the title Hero of the Soviet Union after his battalion captured 5 bunkers and Smirnykh was killed by sniper fire.  Sergeant Anton Buyukly was also made a Hero of the Soviet Union posthumously in 1965 for his sacrifice in blocking a bunker firing slit with his body. Baron Roman Nicolaus Maximilian von Ungern-Sternberg (Russian: Барон Ро́берт-Ни́колай-Максими́лиан Рома́н Фёдорович фон У́нгерн-Ште́рнберг ) (10 January 1886 NS – 15 September 1921) was an anti-Bolshevik lieutenant general in the Russian Civil War and then an independent warlord whose Asiatic Cavalry Division wrested control of Mongolia from the Republic of China in 1921 after its occupation.  He was often referred to as Baron Ungern, or simply Ungern. Alexander Ivanovich Utvenko (Russian: Александр Иванович Утвенко; 12 December 1905 – 20 August 1963) was a Red Army Lieutenant general.  Utvenko became a Red Army officer in the interwar period and was given command of a division after the German invasion of the Soviet Union.

Utvenko took command of the 33rd Guards Rifle Division in August and led that division in the Battle of Stalingrad.  In April 1943 he became commander of the 31st Guards Rifle Corps and led it in the Donbass Strategic Offensive (August 1943).  In the spring of 1944 he began an accelerated course at the Military Academy of the General Staff.  After graduating in early 1945 he became commander of the 38th Guards Rifle Corps which fought in the Vienna Offensive and Prague Offensive in the last months of the war.  Postwar Utvenko continued to command the corps which in the summer of 1946 became an airborne unit.  He graduated from the Military Academy of the General Staff and became commander of the 65th Rifle Corps.  During the early 1950s he served in positions at the Frunze Military Academy and retired in 1954.

In February 1942 he became commander of the 371st Rifle Division and fought in the Battles of Rzhev.  In February 1943 Oleshev was promoted to Major general and became commander of the 36th Rifle Corps from May.  He led the corps during Operation Suvorov and Operation Bagration.  After the capture of Minsk he was appointed the city's military commandant and oversaw cleanup operations in the city.  He then became the commander of the 113th Rifle Corps and led it during the Baltic Offensive and East Prussian Offensive.  Oleshev was promoted to lieutenant general in early May.  During the summer the corps transferred to the Far East and fought in the Soviet invasion of Manchuria in August.  For his leadership in the offensive Oleshev was awarded the title Hero of the Soviet Union. The 137th Rifle Corps was formed on 5 December 1945 in Petropavlovsk-Kamchatsky, part of the Far Eastern Military District, from the Kamchatka Defense Region.  It was commanded by Lieutenant General Alexey Gnechko until May 1950.  Gnechko was a Hero of the Soviet Union and veteran of the Soviet invasion of Manchuria.  The units of the corps were based in Kamchatka and the Northern Kuriles and included the 22nd Rifle Division, 101st Rifle Division and 255th Rifle Division.  In 1948, the 101st Rifle Division became the 6th Machine Gun Artillery Division, which was disbanded in 1953.  After the 1953 disbandment of the 14th Assault Army in Chukotka its 3rd and 8th Separate Rifle Brigades became part of the corps. The division was first formed as the 36th Rifle Division (ru: 36-я стрелковая дивизия) based on the 9th Army's expeditionary division on 19 July 1919.  It fought in the Russian Civil War and was part of the 9th Army between 1919 and 1920.  In summer 1921, the division participated in the campaign against Roman von Ungern-Sternberg's forces in Mongolia.  On 4 June 1923, the division was given the honorary designation "Transbaikal". The 56th Rifle Division was a infantry division of the Red Army of the Soviet Union.  On 21 November 1919 the 56th Rifle Division () was established from a previous rifle division that had been part of the Seventh Red Army.  In June 1941 it was part of the 4th Rifle Corps of the 3rd Army (Soviet Union).  Its first formation was destroyed while serving with 4th Rifle Corps by July 1941.

It was destroyed during the Siege of Sevastopol and was disbanded in late July 1942.  The division was reformed in August 1942 from the 13th Motor Rifle Division NKVD and fought at the Battle of Stalingrad.  For its actions during the battle, the division became the 75th Guards Rifle Division in March 1943.  In April 1943, the division was formed a third time at Kaluga from the 121st Rifle Brigade.  It fought in Operation Bagration. The 300th Rifle Division began service as a standard Red Army rifle division shortly after the German invasion, and fought in the southwestern part of the Soviet-German front for nearly two years following.  It was able to escape the encirclement east of Kiev in September, 1941, and then fought to defend, and later to try to liberate, the city of Kharkov during 1941-42.  After falling back under the weight of the German 1942 summer offensive, the division began distinguish itself during Operation Uranus in late 1942, when it helped defeat the German attempt to relieve Sixth Army and later in the pursuit of the defeated Axis forces and the second liberation of Rostov-na-Donu.  In recognition of these successes it was raised to Guards status as the 87th Guards Rifle Division.  A second 300th Rifle Division was raised a few months later and fought briefly but very successfully against the Japanese in Manchuria in August 1945.
