 The SS executed about 40 prisoners who were unfit for transportation (about 400 others were left behind alive) and approximately 3,200 were marched away on a route leading them some 250 km westward.Hundreds of them died on the way to the Gross-Rosen concentration camp in Lower Silesia, including about 300 who were shot dead in a massacre which occurred on the second night of this death march (in all, about 9,000 to 15,000 Auschwitz system prisoners perished during the evacuation marches).The abandoned camp was liberated on January 19, 1945, by the local unit of the Polish resistance organization Armia Krajowa (AK).
