were later repaired and returned to service, but the recovery of these very large vehicles was difficult. On the first day, the XLVII Panzer Corps penetrated into the Red Army defences before stalling, and the XLI Panzer Corps reached the heavily fortified small town of Ponyri, in the second defensive belt, which controlled the roads and railways leading south to Kursk.
