In mid-1941, the 335th Infantry Division was posted to a position near the border between occupied France and Vichy France. By this time it had reached a strength of over 13,200 personnel. Following the Allied invasion of French North Africa in November 1942, German forces moved into Vichy France in an operation known as "Case Anton". As part of this, the 335th, recently converted into an attack division, seized the port of Marseilles. After five months in Vichy France, it was transferred to the Eastern Front. It fought in several engagements against the Soviets, including the battles at Kursk and along the Dneiper. "Generalmajor" Karl Casper, who had taken over command of the division from Dennerlein just prior to "Case Anton", was wounded during the fighting at the Dnieper and was replaced by "Oberst" Siegfried Rasp.
