After taking heavy casualties on the Eastern Front it was sent back to France for rehabilitation and to serve as a strategic reserve against potential Allied invasion. The division was rushed to Tunisia after Operation Torch (1942) and spent six months in that theatre, where it engaged both British and American forces. It caused severe losses to the "green" US Army in some of their first encounters with the Germans under Field Marshal Erwin Rommel at the Battle of Kasserine Pass (1943).
