Воронежский фронт
The 5th Guards Army and 5th Guards Tank Army of the Steppe Front had been brought up from reserve and reassigned to the Voronezh Front on 8 and 11 July respectively. On 11 July, Vatutin ordered the armies of the Voronezh Front to go over to the offensive on the following day. This Soviet counterattack on the southern side of the Kursk salient was planned to coincide with the offensive against Orel on the northern side, Operation Kutuzov. Vatutin ordered Rotmistrov to destroy the German forces near Prokhorovka with his 5th Guards Tank Army, without allowing the German forces to withdraw southward.
