While on the Romanian front, Sofronov was an active participant in the revolutionary events of 1917, leading a Red Guard detachment to Odessa and taking part in the Bolshevik uprising in that city on January 15-18, 1918. It was as a result of that uprising that Soviet power was established in Odessa.

In March 1918, he went to Moscow where he was active in the 4th Congress of Soviets.

He was among those who put down the rebellion in the Czechoslovak Corps and participated in the execution of the Russian Royal Family.

While pursuing further studies, beginning in 1918, at the Academy of the General Staff of the Red Army, he served as deputy chairman of the party bureau at the academy. In April 1919, after completing one course at the Academy, he returned to the Eastern Front, where he fought against the troops of Admiral A. V. Kolchak.

Interwar period

During the years between the wars, Sofronov served in a number of military roles. In autumn 1921 he was named the commandant of the Arkhangelsk fortified area, provincial military commissar of Arkhangelsk, and commander of the 52nd Separate Rifle Brigade.

In early October 1941, Sofronov had a severe heart attack after receiving news of the death of his only son in battle. On October 5 he was taken to hospital in Sevastopol, and then to Kislovodsk. His health problems would prevent him to return to a position as battlefield commander for the rest of the War. Beginning in April 1942, he was Assistant Commander of the Western Front.
