800 trucks could not possibly have evacuated the German(and Romanian) forces in Stalingrad nor was 14 Panzer Corps capable of lifting out its own men given the lack of fuel. Indeed, as was noted, Paulus could barely move his panzers 20 miles on the fuel he had available. Meanwhile 3000 tons of supplies would amount to @55 pounds of food, fuel, urgently needed medical supplies, spare parts and ammunition per man, hardly enough to rejuvenate the already stricken 110,000 in Stalingrad.
