By noon on 6 July, SS-Panzer-Grenadier Division 1 Leibstandarte Adolf Hitler and the remainder of the SS-Panzerkorps II was twenty miles deep into the Soviet's defense zone. A huge gap had been torn into the Soviet's Sixth Guards Army and the front line lay wide open. However, a crisis situation was building. The Soviets had moved strong tank forces of 5th Guards Tank Army from the northeast into an area just east of the Donets River. II/Panzer-Grenadier Regiment 2 Leibstandarte Adolf Hitler received orders to immediately set out for Luchki II where it was to provide cover for the march route to the west and northwest. At 0500 hours, 7 July the II/Panzer-Grenadier Regiment 2 had just reached their designated defensive position and begun to dig-in when the first wave of Soviet tanks laden with infantry of the Soviet 2nd Guards Independent Tank Corps hit.
Attacker: Russian (Elements 2nd Guards Independent Tank Corps)
