The German Army showed a lot of discipline after being surrounded. Many German soldiers starved or froze to death. Yet, discipline was continued until the very end. General Friedrich Paulus obeyed Hitler's orders and did not attempt to escape out of the city. German ammunition, supplies, and food became scarce. Generals from both sides suffered from massive stress because of the battle and also because of the fact that they had to report to the most brutal leader in their nation's history. Many generals suffered health problems because of their stress.
