The third period lasted from 1942 until the end of the war in 1945, when Albert Speer succeeded Todt in office and the OT was absorbed into the renamed and expanded Reich Ministry of Armaments and War Production. Approximately 1.4 million labourers were in the service of the Organisation. Overall, 1% were Germans rejected from military service and 1.5% were concentration camp prisoners; the rest were prisoners of war and forced labourers from occupied countries.
