'Lenz-Süd' was a German operation in the Belorussia region of the German-occupied western USSR against so-called partisans (largely Jews and other 'undesirables') (30 March/7 April 1943).
Undertaken by a combined force of Sicherheitsdienst personnel, police and SS troops of the Kampfgruppe 'von Gottberg' under the command of SS-Brigadeführer und Generalmajor der Waffen-SS Curt von Gottberg, the operation targeted the area of Borisov, Sloboda and Smolevichi.
