German 11th Army However this had been a great waste of time for the Germans the assault on Stalingrad Operation Blau was just beginning and the Sixth Army under Friedrich Paulus would not have the German 11th Army to support them The German 11th Army was diverted to the northern sector of the Russian front by Hitler This diversion was opposed by Manstien and Hadler The article gives the impression the German 11th Army was not avaiable to assist in the drive toward Stalingrad due to the battle of Sevastopol This impression is incorrect The German 11th Army was avaiable to be used in the southern sector but was diverted by Hitler The battle of Sevastopol had nothing to do with Operation Blue
