was protecting the northern approaches to Kharkov, while Das Reich and LSSAH were defending the eastern approaches to the city. Hausser’s SS-Panzerkorps was still incomplete, since Totenkopf had not yet arrived. On the night of 9–10 February, Rybalko’s 3TA began its deliberate crossing of the Donets with infantry seizing small bridgeheads. On the morning of 10 February, elements of Koptsov’s 15th Tank Corps crossed and seized Pechenegi while General-major Mitrofan I. Zinkovich’s 12th Tank Corps did the same at Chuguyev. German resistance at the river’s edge was light, since the bulk of LSSAH had pulled back into a tighter perimeter closer to the city. The original concept for Operation Star was that Rybalko’s 3TA would envelop Kharkov by manoeuvre, rather than attempting to storm into the city with a frontal assault, but this was now abandoned. On 11 February, Rybalko’s two tank corps, supported by four rifle divisions, began attacking westward straight toward the city. Slow, grinding progress was achieved, but Rybalko’s tanks were being regularly picked off by Panzerjägers and StuG IIIs – this was not how a tank army was supposed to be employed. The Das Reich had established a strong defensive position at Rogan, east of the city, which could not easily be stormed without significant artillery preparation, but Rybalko’s tankers only had limited air and artillery support.
Meanwhile, Sokolov’s 6GCC continued to try and sweep around to the south of Kharkov and Hausser decided to conduct a major counter-attack to remove this threat to his line of communications. A covering force known as the Deckungsgruppe
was left to hold off Rybalko, while an assault formation known as Angriffsgruppe Dietrich was assembled under the LSSAH’s commander SS-Obergruppenführer Sepp Dietrich consisting of three subordinate Kampfgruppen. Kampfgruppe Meyer had the LSSAH’s reconnaissance battalion, Sturmbannführer Max Wünsche’s I./SS-Pz Rgt. 1; Kampfgruppe Kumm consisted of two battalions from the SS-Panzergrenadier-Regiment Der Führer and two companies from II./SS-Pz. Rgt. 1; Kampfgruppe Witt consisted of one infantry battalion from LSSAH, plus engineers, the Sturmgeschütz-Abteilung and artillery.50 In addition, LSSAH committed five of its Tigers to the operation. This was a very large force, including half of Hausser’s available armour and a good portion of his infantry and artillery, leaving the defence of Kharkov short-handed. However, Hausser figured that he would be able to crush Sokolov in a couple of days and then return his forces to defend Kharkov before Rybalko could overcome the blocking position at Rogan. In order to achieve decisive results in warfare one has to accept risk, but that decision has to be based upon sober analysis, which in this case was lacking. The Germans did not have a lot of respect for Soviet cavalry, which heretofore had not been equipped with heavy weapons. However, Sokolov’s 6GCC was quite well equipped, since Rybalko had dispatched it to serve as a mobile group and in addition to its three cavalry divisions, had Polkovnik Ivan T. Afinogenovich’s 201st Tank Brigade (equipped with 25–30 Matilda and Valentine tanks), a multiple rocket launcher battalion, an anti-tank regiment with 76.2mm ZiS-3 guns and an anti-tank battalion with 45mm guns.
