Heeresgruppe F
Army Group F Command in Belgrade sought to bring more units to Belgrade as soon as possible. Commander-in-Chief Maximilian von Weichs ordered the 104th Jäger Division to be transported immediately as soon as transport of the 117th Jäger Division was completed. However, transport from the south was hindered by partisan operations and Allied Air Force attacks. The 117th Jäger Division had been boarded on forty-four trains in Athens on 19 September, but only seventeen of them had reached Belgrade by 8 October. The 104th Jäger Division remained blocked in Macedonia. Because of the lack of troops at the front-line, on 29 September, Army Group F Command ordered a defensive assault by the 1st Mountain Division and the 92nd Motorized Brigade in an attempt to buy time. Assault Regiment Rhodes was transported to Belgrade by air without heavy weapons, but this method of transport could not meet the army's needs.
