Hassebroeck is the Nazi commandant of the concentration camp Gröss-Rosen, which Oskar Schindler’s new Brinnlitz camp is a part of. Hassebroeck sends a telegram to Commandant Liepold near the end of the war about a “final selection” that will eliminate many of the remaining Jews. (The end of the war and Schindler’s maneuvering prevent this from happening at Brinnlitz, however.)
