In the same month he was released from the camp and on 1 September 1942 he was appointed commander of the Russian National People's Army (RNNA), created as an experiment and stationed in the village of Asintorf between Smolensk and Orsha.
By October 1942 there were about 4,000 thousand soldiers in this military unit, but then the German command decided to divide it into battalions, which were to be used separately by the Wehrmacht.
Boyarsky opposed this decision, was arrested, but was soon released and appointed officer in command and training of the Eastern Volunteer Forces at the headquarters of the 16th Army.
From January to May 1945, he was Deputy Chief of Staff of the Russian Liberation Army under command of General Fyodor Truhin.
On 5 May 1945, by order of Truhin, he went to the Prague area to establish contact with the most combat-ready military unit of the KONR – the 1st Infantry Division of General Sergey Bunyachenko.
