Battle of Stalingrad on Soviet records, over 10,000 German soldiers continued to resist in isolated groups within the city for the next month. Some have presumed that they were motivated by a belief that fighting on was better than a slow death in Soviet captivity. Brown University historian Omer Bartov claims they were motivated by National Socialism. He studied 11,237 letters sent by soldiers inside of Stalingrad between 20 December 1942 and 16 January 1943 to their families in Germany. Almost every letter expressed belief in Germany's ultimate victory and their willingness to fight and die at Stalingrad to achieve that victory. Bartov
Battle of Stalingrad only between 10,000 to 60,000 civilians were still alive in Stalingrad. Much of the city was quickly turned to rubble, although some factories continued production while workers joined in the fighting. The Stalingrad Tractor Factory continued to turn out T-34 tanks literally until German troops burst into the plant. The 369th (Croatian) Reinforced Infantry Regiment was the only non-German unit selected by the "Wehrmacht" to enter Stalingrad city during assault operations. It fought as part of the 100th Jäger Division. Stalin rushed all available troops to the east bank of the Volga, some from as far away as Siberia. All
