By February 1943, Flossenbürg had 4,004 prisoners, not including the Soviet prisoners of war. From April 1943, the commandant was Max Koegel, described by American historian Todd Huebner as "a vicious martinet" who lacked the ability to manage the camp during its rapid expansion. Continuing influxes of political prisoners from occupied countries caused Germans to become a minority that same year. During 1944, Flossenbürg's population expanded almost eightfold, from 4,869 to 40,437, due to a high influx of mainly non-German prisoners. This was part of an expansion that applied over the entire Nazi concentration camp system.
