In August 1942, Bergmann went to the Eastern Front, where it saw its first action in the North Caucasus campaign in August 1942. The unit engaged in anti-partisan actions in the Mozdok-Nalchik-Mineralnye Vody area and conducted reconnaissance and subversion in the Grozny area. At the end of 1942, Bergmann conducted a successful sortie through the Soviet lines, bringing with them some 300 Red Army defectors, and covered the German retreat from the Caucasus. Bergmann went through a series of engagements with the Soviet partisans and regular forces in the Crimea in February 1943 and was dissolved—like other "Ostlegionen" units—at the end of 1943. The significantly shrunken ex-Bergmann companies were dispatched to conduct police functions in Greece and Poland.
