One more question, how do you explain the reasons for the stubborn resistance of the German forces at the end of January 1943:
1. Fear of Russian captivity.
2. The fear of German military tribunal.
3. Military discipline and military tradition in the Wehrmacht.
Sometimes, it seems, if Paulus gave the order to surrender, many soldiers and officers would still be fought.
Another question. In the Stalingrad kessel or earlier, to you known cases of execution German soldiers on a sentence of a military court? As well, if a soldier goes over to the enemy, his family at home will be punished?
