Over the next few months, "Langemarck", along with the remainder of Steiner's Corps, executed a fighting withdrawal into the Kurland Pocket, the brigade being in combat for much of the retreat. In September 1944, the remains of KG Rehmann were evacuated by ferry over the Baltic to Swinemünde and joined the rest of the Brigade. Following the allied invasion of Belgium, many Belgian fascists fled the country to Germany. The result of this was that both the "Langemarck" and the 5th SS Volunteer Sturmbrigade "Wallonie" were redesignated as divisions on 18 October 1944.
