On 17 October 1918 "for distinction in combat and distinguished service" he was promoted by the Czechoslovak National Council to major-general and appointed commander of the Samara group of troops of the Government Directorate.

He commanded defensive battles in the Volga region: not only did he stop the advance of the Red forces, but he threw them back across the Ik River, securing a firmer footing on the white Samara front.

Major-general Voytsekhovsky was awarded the Order of St. George 4th degree in July 1919 for having captured Chelyabinsk, Troitsk, Chrysostom, and Yekaterinburg in 1918.

Then he turned his force northwards during the battle and destroyed the enemy on the Siberian Army front, than let her go ahead, although it is early in the course of the failed counter-attack.

As a supporter of strict discipline he personally shot and killed, on 20 November 1919 in the village of Ust-Tarka, Major-General P. P. Grivin for unauthorized abandonment of his front that forced the retreat of Wojciechowski's southern group.

After the death of General Vladimir Kappel on 25 January 1920 during the Great Siberian Ice March, Major-General Voytsekhovsky succeeded him as Chief of the Eastern Front.

[2] He supervised the entrance of the White Army into Irkutsk and on 30 January 1920 destroyed the red troops in that area and on 1 February 1920 also took the suburb of Cherm.

But by May 1920, Voytsekhovsky was seconded to the Crimea to establish a connection with the Armed Forces of South Russia, becoming the Army Reserve of General Wrangel.

During the Munich crisis of 1938 he took an active anti-capitulatory position (at that time one of the advocates of surrender was General Jan Syrový) and for that in April 1939 he was discharged.

On 12 May 1945, despite being a Czechoslovak citizen, Voytsekhovsky was captured in Prague by a Soviet military counter-intelligence commando SMERSH and immediately abducted to Moscow.

On 25 May 1949, he was transferred again, this time to a recently established special GULAG camp MVD Ozerlag for political prisoners in Irkutsk Oblast.
