In December 1942, Bunyachenko was captured by a reconnaissance group of the 2nd Romanian Infantry Division, 25 km west of Vladikavkaz. He was held in a concentration camp in Crimea and Kherson from his capture until June 1943. In May, he applied to join the
Russian Liberation Army, a collaborationist anti-Communist force led by General
Andrey Vlasov. By September 1943, he had been approved to serve as a communications officer in the headquarters of the
German 7th Army in
Le Mans, in the Sarthe department. In June and July 1944, he led a combined regiment of two Eastern battalions in a defense against
Operation Overlord in an unknown portion of the French coast. He was awarded the Iron Cross 2nd class for his actions on the Western Front. On 10 November 1944 he was promoted to commander of the
600th Infantry Division (1st Infantry Division of the ROA), leading a total of twenty thousand soldiers and auxiliary personnel. In February 1945 Bunyachenko was promoted to Major General, and was rotated to the Eastern front in March. In Mid-April he participated in Operation: April Weather, an effort to defend the
Oder River, which today marks the German-Polish border, from the encroaching Red Army. When Operation: April Weather failed, General Bunyachenko ordered his troops to withdraw from the river into Czechia on 16 April. One source alleges that Vlasov and Bunyachenko together intended to muster the ROA in Slovenia and strike against
Josip Tito's partisans. This source states that the ROA intended to retake Slovenia and portions of Croatia and Northern Bosnia and establish a "White Yugoslavia" which would be friendly to the Allies and particularly America in the war's aftermath. This source is not corroborated, and should be treated with skepticism. It is, however, a matter of historical record that the ROA and Bunyachenko defected from the Nazis and attempted to align themselves to the Western Allies as the fall of the Third Reich approached. ==The Prague Uprising==
