Under pressure from heavy Soviet counterattacks during the winter, the LSSAH and Army Group South retreated from Rostov to defensive lines on the river Mius. After the spring rasputitsa (seasonal mud) had cleared, the division joined in "Fall Blau", participating in the fighting to retake Rostov-on-Don, which fell in late July 1942. Severely understrength, the LSSAH was transferred to the Normandy region of occupied France to join the newly formed SS Panzer Corps and to be reformed as a Panzergrenadier division.
