On 2 October, the German command structure was reorganized and General Friedrich-Wilhelm Müller, former commander of German forces on Crete, resumed command over the front-line south of the Danube. His Corps headquarters was located in Kraljevo. General Wilhelm Schneckenburger retained command of the forces north of the Danube and was tasked with the immediate defense of Belgrade.
