 On 2 September, two squadrons (companies) of the division's cavalry battalion (formerly "Kosaken-Schuma-Abteilung 68" and redesignated the "Waffen-Reiter-Abteilung der SS 30") were surrounded and destroyed in a surprise attack at Melin by the Ukrainians who had defected in the Confracourt Woods.The subsequent investigation of these events by German authorities resulted in some 2,300 men in the division being deemed "unreliable".As punishment, these personnel were transferred to two field entrenchment construction regiments () subordinated to the Karlsruhe Transport Commandant, leaving some 5,500 men still in the division.
