On the other side, the German Army showed remarkable discipline after being surrounded. It was the first time that it had operated under adverse conditions on such a scale.
During the latter part of the siege, short of food and clothing, many German soldiers starved or froze to death. Yet, discipline was maintained until the very end, when resistance no longer served any useful purpose. Friedrich Paulus obeyed Hitler’s orders, against many of Hitler’s top generals’ counsel and advice including that of von Manstein, and did not attempt to break out of the city. German ammunition, supplies, and food became all too scarce.
Paulus knew that the airlift had failed and that Stalingrad was lost. He asked for permission to surrender to save the life of his troops but Hitler refused and instead promoted him to the rank of Generalfeldmarschall. No German officer of this rank had ever surrendered, and the implication was clear. If Paulus surrendered, he would shame himself and would become the highest ranking German officer ever to be captured. Hitler believed that Paulus would either fight to the last man or commit suicide. Choosing to live, Paulus surrendered, commenting that: “I have no intention of shooting myself for that Bavarian corporal”.
Paulus didn't give the order to 6th Army to surrender, but his troops no longer had much fight left in them. Resistance faded out over the next two days, with the last die-hards finally calling it quits. One Red Army colonel shouted at a group of prisoners, waving at the ruins all around them: "That's how Berlin is going to look!"
The ruins of the city fell quiet. Civilians -- astonishingly, roughly ten thousand had survived through the entire battle -- began to emerge from the rubble. On 2 February, a Luftwaffe Heinkel He-111 bomber made a flight over Stalingrad in order to drop supplies to survivors, if they could be found. After searching for a time, the radio operator told the pilot: "Nothing anywhere." The bomber flew back to its home base.
The battle of Stalingrad was over. The Russian-born correspondent Alexander Werth of the LONDON SUNDAY TIMES documented the ghastly scenery of the city after the shooting had stopped:
"Trenches ran through the factory yards and through the workshops themselves. And now at the bottom of the trenches there still lay frozen green Germans and frozen gray Russians and frozen fragments of human shapes; and there were helmets, Russian and German, lying among the brick debris, and now half-filled with snow."
Roughly 100,000 German troops went into captivity. The catch included 22 generals, who were given good food and comfortable quarters. Alexander Werth got to interview them after the battle, finding them all clearly far better fed than their troops, though Werth noted that Paulus "looked pale and sick, with a nervous twitch in his left cheek." The embittered Paulus would eventually perform propaganda broadcasts for the Soviets. As far as his men went, they weren't as valuable as prizes and were treated accordingly. Only about 5,000 would ever return from Soviet prison camps.
Stalingrad was the German high tide in the East. 20 German divisions had been effectively destroyed, 6th Army had been completely wiped out, and six months' German war production had been lost. The armies of Italy, Hungary, and Rumania had suffered major blows. Both sides had lost very roughly 750,000 men each. To the Germans, it was a disaster, though Hitler blamed it all on the failings of his weakling allies. Heinz Guderian visited the Fuehrer in the aftermath and found him lacking his customary energy: "His left hand trembled, his back was bent, his gaze was fixed, his eyes protruded but lacked their former luster, his cheeks were flecked with red."
Goebbels' propaganda machine played up the German troops who had fallen in the battle as martyrs to the Nazi cause, and declared that Germany was now committed to "Total War", a total mobilization to obtain final victory in the face of adversity. Hitler still thought he could win through sheer power of will, telling Luftwaffe Field Marshal Erhard Milch: "We will end the war this year. I have accordingly decided on a gigantic mobilization of all German popular strength."
For the Soviets, the losses that they had suffered did not obscure the all-important fact that they had won. One soldier wrote his wife: "I'm in an exceptional mood. If you only knew, you'd be just as happy as I am. Imagine it -- the Fritzes are running away from us!"
