On 16 October, Rotmistrov brought the rest of 18 TC and 29 TC across the Dnepr and pressed the attack, quickly forcing the 23.Panzer-Division back, which created a 10km-wide gap in the German front. A Soviet tank brigade pressed into the gap, overrunning the 23.Panzer-Division’s Flak-Bataillon, then pushing on to attack Großdeutschland
’s divisional command post. Although Vormann managed to gather up three Panthers and three Pz IVs to conduct a mobile screen in the gap, they offered little serious resistance to Rotmistrov’s mass of armour. By the third day of the offensive, Rotmistrov’s armour had achieved a clear breakthrough and surged forward to overrun Vormann’s command post and support units in Popel’naste. Although the Germans claimed to have knocked out many of Rotmistrov’s tanks, the fact is that Soviet tanks were roaming in the rear areas, shooting up German support units. Both 23.Panzer-Division and Großdeutschland were forced to abandon many damaged tanks at workshops, leaving them with a combined total of about 12–15 operational tanks. Rotmistrov kept the pressure on, continuing to advance at night, in order to prevent the Germans from forming a new line. Soon, Kirchner’s LVII Panzerkorps headquarters was threatened by Soviet tanks and had to flee, causing a disruption in German C2 at a critical moment. Panic set in, as German support units fled rearward without orders – not unlike French troops in May 1940. It just got worse and worse for PzAOK 1, as Rotmistrov’s armoured fist exploited rapidly to the south. In life, there are few experiences as exhilarating as an armoured pursuit of a broken enemy and this must have been a heady moment for Rotmistrov’s tankers, as well as sweet revenge for Prokhorovka.Vormann’s 23.Panzer-Division tried to mount a defence of the rail station at P’yatykhatky, but this effort fell apart and Soviet tanks reached the virtually undefended town at 2030 hours on 18 October. At the train station, the Soviet desant
troops on the T-34s discovered flatcars loaded with 10 brand-new Tiger tanks, destined for Großdeutschland.191 Another train in the station was discovered loaded with wounded German troops, who were unceremoniously dispatched by the victorious Soviet Desantniki with grenades and small arms. Meanwhile, a massive column with over 3,000 German vehicles was fleeing from the as yet unoccupied southern side of the town. Spotting the escaping enemy, Soviet T-34s fired high explosive rounds into the column, inciting a panic.192 Vormann’s 23.Panzer-Division was wrecked, with only 10 tanks left, 30 men in Panzergrenadier-Regiment 126 and 29 in Panzergrenadier-Regiment 129. Having shattered the connection between PzAOK 1 and AOK 8, Konev was faced with the decision of whether to push west to Kirovograd to roll up AOK 8’s right flank or south to Krivoi Rog, to threaten PzAOK 1’s line of communications. He opted to split his forces and attempt to seize both objectives: Skvortsov’s 5 GMC and the 53rd Army would push toward Kirovograd while the 18 TC and 29 TC advanced to Krivoi Rog. The Germans were literally reeling from the Soviet armoured breakthrough and resistance was patchy, which allowed the 5 GMC to reach Novo Starodub on the Inhulets River on 22 October and the rest of Rotmistrov’s 5 GTA reached the outskirts of Krivoi Rog on 27 October. Mackensen’s PzAOK 1 was threatened with envelopment by the Soviet advance, which forced him to abandon Dnepropetrovsk on 25 October. Malinovsky’s 3rd Ukrainian Front swarmed across the Dnepr with three armies.
