Wilhelm Keitel
Hitler took personal command of the armed forces through the new "Oberkommando der Wehrmacht" (OKW) after the defeat outside Moscow in December 1941 and appointed himself as commander of the "Oberkommando des Heeres" (OKH) after Walther von Brauchitsch was relieved and transferred to the leadership reserve (Führerreserve). Hitler then began participating at OKW, where Field Marshal Wilhelm Keitel never dared to oppose him.
