By the end of 1943, the number of guards had increased to about 450, including 140 Ukrainian auxiliaries. As with other concentration camps, guards initially consisted of SS men from Germany and Austria, whose ranks were augmented with "Volksdeutsche" recruits after 1942. The number of guards increased sixfold during 1944 and reached 4,500 by the time the camp was evacuated. Due to manpower shortages, fit young guards were called up for front-line service and many older men, members of the Wehrmacht, and five hundred SS women were recruited into the guard force at Flossenbürg.
