 Fighting raged inside the Barrikady Factory until the end of October.The Soviet-controlled area shrank down to a few strips of land along the western bank of the Volga, and in November the fighting concentrated around what Soviet newspapers referred to as "Lyudnikov's Island", a small patch of ground behind the Barrikady Factory where the remnants of Colonel Ivan Lyudnikov's 138th Rifle Division resisted all ferocious assaults thrown by the Germans and became a symbol of the stout Soviet defence of Stalingrad.From 5 to 12 September, "Luftflotte 4" conducted 7,507 sorties (938 per day).
