By October 1941, the German military advance into the Soviet Union reached the area of Lokot near Bryansk, which was captured by German forces on 6 October 1941. In November 1941, Kaminski, along with his close friend, a local technical school teacher,
Konstantin Voskoboinik, approached the German military administration with a proposal to assist the Germans in establishing a civil administration and local police. Voskoboinik was appointed by the Germans as the Starosta (or Mayor) of the "Lokot volost" and the head of the German-controlled local militia. Kaminski became Voskoboinik's deputy; working with
Heinz Guderian the two collaborators organized a militia of 10,000 armed men with the aim of crushing the Russian partisans. After the
death in combat of Voskoboinik on 8 January 1942, Kaminski took over as Mayor and leader of the militia. In 1942 the militia was named Russian Liberation National Army (RONA) (rus. Русская Освободительная Народная Армия), which reached a force of tens of thousands. During this time Kaminski was leader of the Lokot Republic, which had half a million inhabitants. In mid March 1942, Kaminski's representative at the German Second Panzer Army at
Orel assured the commanders that Kaminski's unit was "ready to actively fight the guerrillas" as well as to carry on a propaganda campaign against "
Jewish Bolshevism" and
Soviet partisans. Soon after the commander of the
2nd Army Generaloberst
Rudolf Schmidt, appointed Kaminski Major of the Army Rear Area 532, around Lokot. On 19 July 1942, after approval by the Commander of
Army Group Centre, Field Marshal
Günther von Kluge, Schmidt and the 532 Area commander, Kaminski received a degree of autonomy and nominal self-governing authority, under the supervision of Major
von Veltheim and Colonel
Rübsam. Kaminski was appointed the Chief Mayor of the republic of Lokot, and brigade commander of the local militia. He administered local government and established his own courts, jails and newspaper. Private enterprise was encouraged and
collective farming abolished. From June 1942, Kaminski's militia took part in an action, "
Operation Vogelsang", as a part of General
Werner von Gilsa's Kampfgruppe (taskforce) Gilsa II. In autumn 1942, Kaminski ordered a compulsory draft into the militia of able-bodied men in the area. Units were also reinforced with "volunteers" drafted from Soviet POWs at nearby Nazi concentration camps. Kaminski ordered the collection of abandoned (usually because of minor mechanical failures, or lack of fuel) Soviet tanks and armored cars. By November 1942, his unit was in possession of at least two
BT-7 tanks and one 76 mm artillery piece. Owing to a lack of military uniform and boots, the Germans provided Kaminski's brigade with enough used uniforms to outfit four battalions. By late 1942, the militia of the
Lokot Republic had expanded to the size of a 14-
battalion brigade, of around 8,000 men under arms. By January 1943 the brigade had 9,828 men, including an armored unit with one KV-2 heavy tank, two T-34 medium tanks, three BT-7s, two BT-5 light tanks and three armoured cars (one BA-10, two BA-20). The brigade was reorganized in the spring of 1943. After the reorganization, the brigade consisted of 5 regiments with 3 battalions each, an anti-aircraft battalion (3 AA guns and 4 heavy machine guns) and an armored unit. A separate "guard" battalion was also created, bringing the total brigade strength up to an estimated 12,000 men. The brigade took part, with German units, in the May–June 1943
Operation Zigeunerbaron ("Gypsy Baron"). Following this operation, the brigade was part of
Operation Citadel, the offensive to destroy the
Kursk salient. This operation was followed by similar operations, Freischütz and Tannhäuser, where the brigade, together with other units under German command, was involved in action against
partisans and also took part in
reprisal operations against the civilian population. In the summer of 1943, the brigade began to suffer many desertions, due in part to the recent Soviet victories, but also due in part to the efforts of the partisans to "turn" as many of Kaminski's troops as possible. As a part of these efforts, there were several attempts on Kaminski's life. Each time, Kaminski narrowly avoided death and any captured conspirators were punished by execution. Several German officers passing through Lokot reported seeing bodies hanging from
gallows outside Kaminski's headquarters. Fearing a breakdown in command, a German liaison staff was attached to Kaminski's HQ to restructure the brigade and return stability to the unit. According to post-war Soviet estimates, up to 10,000 civilians were killed during the existence of the Kaminski formation in Lokot. ==In Belarus==
