Facing Hoth’s 4.Panzerarmee, Vatutin had arrayed his Voronezh Front forces in great depth. General-leytenant Ivan M. Chistiakov’s 6th Guards Army (6 GA) was deployed in a two-up/one-back style echeloned defence across a 60km-wide front, with the 22nd Guards Rifle Corps (22 GRC) opposite XXXXVIII Panzerkorps and the 23rd Guards Rifle Corps (23 GRC) opposite the II. SS-Panzerkorps. In tactical reserve, Chistiakov had the 96th Tank Brigade (46 T-34s and 5 T-70) and the 230th and 245th separate tank regiments with a total of 34 M3 Grants and 44 M3 Stuarts. More importantly, Chistiakov had the 27th and 28th Anti-tank Brigades in general support, plus 10 separate anti-tank regiments which were attached to his rifle divisions, providing 6 GA with a total of 573 anti-tank guns.{86} However, Chistiakov’s sector only had half the density of mines that Pukhov’s 13th Army had on the northern front and, unlike Rokossovsky, Vatutin had not deployed an artillery corps to support the main defence. With fewer mines and less artillery support, Chistiakov’s front was not as dense a defence as Model had confronted in the north.
Behind Chistiakov’s 6 GA, Vatutin deployed the 69th Army in a third line of defence with five rifle divisions, the 35th Guards Rifle corps and General-leytenant Mikhail E. Katukov’s 1st Tank Army, comprised of the 6th and 31st Tank Corps and 3rd Mechanized Corps. Altogether, Katukov had 587 tanks of which 484 were T-34s – an unusually high proportion of medium tanks for the Red Army in mid-1943. Vatutin kept two more tank units, the 2nd and 5th Guards Tank Corps with a total of 410 tanks, under his control in front reserve. Vatutin’s intent was to use Katukov’s armour and the two separate tank corps to mount local counter-attacks to block any German breakthroughs, rather than as a masse de manoeuvre. General-leytenant Mikhail S. Shumilov’s 7th Guards Army (7 GA) opposed Armee-Abteilung Kempf with the 25th Guards Rifle Corps in a 2-up/1-back defensive echelon, supported by two tank regiments with 33 T-34 and 22 KV-1s.
The long-awaited Panther tanks arrived by rail near Borisovka, beginning on 1 July, and the last trainload did not arrive until 4 July, the day before Zitadelle was to begin. All the technical problems aside, Hoth had made little effort to ensure that the two Panther-Abteilungen had proper command and control or were integrated into PzAOK 4’s tactical plans. The 10.Panzer-Brigade was established in Berlin on 27 June under Oberst Karl Decker to command the Panthers, but the headquarters did not even begin moving to the Eastern Front until 3 July.[22] This mistake was another indicator that the efficiency of the German Panzertruppen was slipping by 1943. Realizing that someone had dropped the ball, Major Meinrad von Lauchert, who had been involved with training Panther crews at Grafenwöhr, formed the provisional Panzer-Regiment 39 to control the Panthers arriving at the Borisovka railhead. The Panthers were put under the operational control of Großdeutschland, which gave von Lauchert a radio command vehicle and enough resources to operate a small tactical command post. However, this ad hoc solution all occurred in the last evening before Zitadelle began, which meant that coordination and the tactical orders process were curtailed. One-third of the Panther crews had no combat experience and now they were being asked to go into battle attached to an unfamiliar unit and with vague tactical orders. Making matters significantly worse, there was no opportunity at the railhead to bore-sight the main guns (which after a long, bumpy train ride would definitely be out of alignment with the gunner’s sights) or to set radios to correct frequencies. As soon as they left the railhead, Panthers began breaking down on the 35km road march to the assembly area near Tomarovka and by the time they reached it, only 166 out of 204 Panthers were still running.{87} Two Panthers were completely burnt-out by engine fires.[23]
While the Panthers were moving up to the front, Hoth’s PzAOK 4 was already making its initial moves in Zitadelle. At 1450 hours on 4 July, Stukas from Luftflotte 4 conducted a massive airstrike against positions in the 6 GA’s forward security zone, followed by an artillery bombardment from XXXXVIII Panzerkorps. Hard on the heels of the artillery barrage, infantrymen from both corps began an aggressive counter-reconnaissance probe to overrun Soviet units in their forward security sector. Most of the action involved battalion-size probes to eliminate Soviet artillery observation posts and to begin clearing the outer minefields. No tanks were involved in this effort, but assault guns and reconnaissance vehicles moved forward. In contrast to von Knobelsdorff’s broad daylight approach, Hausser’s II.SS-Panzerkorps did not begin its own counter-reconnaissance effort until after dusk. Hoth’s troops succeeded in capturing a few villages and hilltops, but were shocked by the difficulty of clearing paths through the minefields and the heavy casualties. Nor were all the Soviet outpost positions or mines eliminated in the security zone.{88}
Unlike the northern front of Operation Zitadelle, the operations of von Manstein’s southern pincer have been covered in great detail in a large body of literature and I do not intend to belabour this well-known side of the Battle of Kursk with a blow-by-blow description. In particular, this task has already been well accomplished by George M. Nipe’s Blood, Steel and Myth (2011) and Valeriy Zamulin’s Demolishing the Myth, which both provide great day-to-day detail on the fighting on the southern side of the Kursk salient. Instead, I intend to focus the remainder of my discussion of Zitadelle on the main implications for armoured warfare on the Eastern Front on three particular topics: (1) how von Manstein’s armour penetrated the Soviet obstacle belts, (2) the poor performance of the Panther tank in its initial combat debut and (3) Rotmistrov’s botched counter-attack at Prokhorovka. I also intend to avoid the simplistic pitfall of earlier analyses, which tend to base their assessment of Zitadelle upon numbers of operational tanks on either side and little else.
Hoth’s main attack began at 0500 hours (local) after a 45-minute artillery preparation. On the left flank, von Knobelsdorff’s XXXXVIII Panzerkorps attacked with the 3.Panzer-Division, Großdeutschland and 11.Panzer-Division advancing on line. The Panther-Abteilungen were still in their assembly area and did not move forward until about 0900 hours. There were still plenty of uncleared mines in the former Soviet security, which greatly complicated the forward movement of the German assault groups. Generalleutnant Franz Westhoven’s 3.Panzer-Division attacked with four of its Panzergrenadier-Baitallonen, without the planned armoured support, against the Soviet 210th Guards Rifle Regiment. After clearing out the frontline positions, the German battalions were stopped for nearly five hours by a deep, muddy balka. While the German pioniers established a crossing, Soviet artillery pounded the stalled Germans, inflicting heavy casualties. When the balka was finally bridged around 1400 hours, Westhoven’s infantry poured across, along with tanks from II./Panzer-Regiment 6, and attacked the village of Korovino. The village was captured, but Oberst Gunther Pape, commander of Panzergrenadier-Regiment 394, was badly wounded. A minor counter-attack by Soviet tanks was repulsed by the German panzers. Westhoven’s division had overrun a first-line rifle regiment and advanced a total of about 5km.

Decker and his brigade headquarters did not arrive until 11 July, by which point there were very few Panthers left to command.

The engine fires were caused by excessive heat, caused by a rubber liner installed in the engine compartment intended to keep the compartment dry in river-crossings. However, the rubber lining also retained engine heat and resulted in the destruction of a number of Panthers.
