Hitler had ordered the bridgeheads of Serafimovich and Kletskaya destroyed but the Red Army was able to hold onto these which were the key to starting the offensive to surround Stalingrad.

Also to the Northern sector Hitler had sent a panzer division to secure the area from Soviet breakthroughs but once the operation started these were no match for the massive Soviet offensive. I think Hitler also ordered the panzer division General to be executed for not doing his duty.
