While Hitler rested amidst the stunning beauty of Bavaria, Stalin listened to his commanders finalize their brilliant plan ("Operation Uranus") to take back Stalingrad. Initially unsure the Red Army could effectively mount a surprise counter offensive, Stalin was ultimately persuaded by Marshal Zhukov. The plan could work, but only a few men would know about it. Even field commanders were kept in the dark.

Plans to launch the attack were changed from November 9 to November 19th due to weather. As the Red Army began to move, some of the German commanders wondered: Were the Russians commencing a counter attack? Hitler, wrongly convinced the Soviets did not have enough reserves to mount a significant assault, was also mistaken about something else.

At a time when German women were not permitted to work in factories, Soviet women were out-producing Nazi factories four-fold. For every 500 tanks made in Germany, 2200 tanks were turned out in Russia. Many of those tanks were about to bear down upon the 6th Army and the 4th Panzer Army. Within days, General Paulus and his men would be trapped with no reasonable method of escape.
