he Gross-Rosen Concentration Camp was initially organized as a subcamp for Sachsenhausen. It became an independent camp in 1941. Prisoners were sent to work in the nearby granite quarry, and as the camp expanded, many prisoners worked in the factories of several subcamps. The most famous of Gross-Rosen's subcamps was Brunnlitz where the workers of Oskar Schindler's textile factory were interned. Overall, Schindler saved over a thousand Jews who worked in this camp. Gross-Rosen was a large and very typical Nazi concentration camp. In 1944, Gross-Rosen reached its peak population, holding eleven percent of all Nazi prisoners in the main and subcamps. When the Soviet Army began moving west, thousands of Jews were transferred from Auschwitz and other Polish camps to Gross-Rosen where they were interned until the Soviets liberated the camp in February 1945.
