The Stavka had been expecting von Manstein to retreat to the Dnepr at any time and once indications of withdrawal were detected by Soviet aerial reconnaissance, Stalin issued orders directly to the fronts for the advance to the Dnepr. Five fronts surged toward the Dnepr with over two million troops and 2,000 tanks. Vatutin would head for Kiev and the Dnepr Knee and was provided Rybalko’s partly-refitted 3 GTA (7 GMC, 9 MC, 6 GTC, 7 GTC, 91 TB) to act as a mobile group (
Recognizing the difficulty of crossing the Dnepr, the Stavka began preparing several airborne brigades to support an assault crossing of the Dnepr. Vatutin was given operational control over a provisional airborne corps (1st, 3rd and 5th Guards Airborne Brigades) with 10,000 paratroopers and the authority to employ them. On the night of 19–20 September, Rybalko’s 3 GTA began advancing toward the Dnepr, with Podpolkovnik Trofim F. Malik’s 56th Guards Tank Brigade as the advance guard. The Stavka believed that the Germans would have all the major crossing sites well defended (a false assumption, as it turned out) so Rybalko was ordered to head for the so-called ‘Dnepr Knee,’ a great bend in the river south of Kiev and near the Kanev crossing site. Soviet partisans had reported that there were no German forces in this area and the Stavka hoped that Rybalko could ‘bounce’ this undefended section of the Dnepr before the Germans arrived.
Nehring’s XXIV Panzerkorps retreated toward Kanev with the 10.Panzergrenadier-Division, Sturmgeschütz-Abteilung 239 and elements of three battered infantry divisions. Unknown to him, Rybalko’s armour was coming up fast behind him, but Nehring did not opt to conduct any delaying actions. Oberst Hans Källner’s 19.Panzer-Division crossed the Dnepr at Kiev on 20 September, the first of von Manstein’s armoured units to regain the western bank. Even before Källner’s division was assembled in Kiev, he was ordered to dispatch his reconnaissance battalion to the Dnepr Bend to look for any signs of Soviet crossing activity. Meanwhile, the III. and XXXXVIII Panzerkorps fought a bitter – and futile – delaying action at Poltava on 20–22 September against Konev’s forces, before abandoning the city on 23 September.
