The new 28th SS Volunteer Grenadier Division "Wallonia" (28. SS-Freiwilligen-Grenadier-Division Wallonien) was created in October 1944, but only numbered approximately 4,000 men, making it considerably understrength.[14] French and Spanish soldiers from the Legion of French Volunteers Against Bolshevism (LVF) and Blue Division were folded into the unit to increase its numbers.[15] During the retreat, Walloon soldiers participated in the massacre of 6,000 Jewish female prisoners of Stutthof concentration camp in January 1945.[16] The remains of the "division" saw action during Operation Solstice in February 1945 and was forced to retreat through Central Pomerania near Stettin on the Oder river. After mass defections in April its remaining 400 personnel fled to Lübeck where they surrendered to the British Army.
