In the defense zone of the SWF, from the Southern Front, 2CC (5, 9CDs) was transferred, on the basis of which the Cavalry Mechanized Group (CMG) of General Belov was formed: 2CC, 1, 129TBdes and 100RD. The CMG units of Belov were tasked with delivering a strike in the direction of Romny, to assist the encircled troops of the SWF. To the south of CMG Belov, a group of 5CC and 110TBde operated, deployed from the 38A sector.
On September 19, 9CD (2CC) received an order to attack in the direction of Romny and capture the bridges across the Sula River. 129TBde was transferred to the front line immediately after its formation, so the personnel recruited from different units were not well-coordinated together. The brigade consisted of three tank and one motorized rifle battalions.
In order to prevent the encirclement from breaking through, its outer perimeter is reinforced by elements of German motorized divisions: 10MID and MID SS "Das Reich". 41MIR (10MID) moved behind 3TD, occupied a bridgehead on the Sula River east of Romny. The main forces of the 10MID are advancing on the crossings on the northern bank of the Sula River near Korovnitsy. MID SS "Das Reich", by forced march was transferred through Priluki to the area west of Romny. 41MIR passes into its subordination. The engineering battalion SS "Das Reich" ensures the division's crossings across the Sula River. The division was ordered to advance in the general direction towards Korovnitsy with the support of 3 battalions from AR SS.
