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
Bombing of Stalingrad Stalingrad. During the Battle of Kalach, "Fliegerkorps VIII" provided the German XIV and XXIV Panzer Corps' with decisive air support as the Soviet 62nd Army was encircled and destroyed west of Kalach from 8–11 August through the application of superior German firepower from all sides and especially from above. 50,000 prisoners were taken by the Germans, 1,100 Soviet tanks were destroyed or captured and the road to Stalingrad was laid bare. LI Army Corps penetrated across the Don north of Kalach on 21 August, forcing the surprised and helpless Red Army formations to the south to fall back on Stalingrad.
