In November 1943, the new SS-Sturmbrigade Wallonia was deployed for the first time to the Ukraine in response to the Soviet Dnieper–Carpathian Offensive. There, the brigade fought as part of the SS Wiking Panzer Division in the Korsun–Cherkassy Pocket in February 1944 and suffered 70 percent casualties.[14] Among those killed was the unit's commander Lucien Lippert.[15] A detachment also fought at the Tannenberg Line in Estonia in June 1944, suffering heavy losses.
