On this day, 84 years ago, on December 5, 1941 (October 17, 1941 in the lunar calendar), the Soviet Union launched a counterattack against the German army under the city of Moscow. Severe cold, heavy snow and the Soviets 'belief in victory prevented the Nazis from launching the blitz. In mid-November 1941, the German army had surrounded Moscow from three directions: north, south and west, with a total strength of more than 80 fully manned armored and infantry divisions. Supported by aviation and artillery, they attacked the Moscow garrison from all directions. They were desperate to rush into Moscow at all costs. The fiercest attacks encounter the most tenacious defenses. At the most critical moment, Zhukov received a phone call from Stalin. In his memoirs, he repeated Stalin's original words at the time: "Comrade Zhukov, do you firmly believe that we can hold Moscow? I am asking you this question with great pain in my heart. I hope that as a member of the Communist Party, you will answer honestly." Zhukov replied honestly that the Red Army could hold Moscow, but it would need to replenish at least two army groups and 200 tanks. On December 2, a German reconnaissance battalion broke into the outskirts of Moscow and saw the steeple of the Kremlin, but was quickly repelled. This was the first and last time the German army saw the Kremlin. December 5, 1941 was a critical day. The German army was stopped in a semicircular position hundreds of kilometers long around Moscow. Both the offensive and defensive sides were exhausted. At this time, it was up to who could get reinforcements from a strong new force. This was the moment Stalin had been waiting for for a long time. He has a strong reserve team at his hands, but it depends on when he will use it. He had to wait until it was no longer possible for the German army to deploy a new heavy group before releasing his own heavy group. The Soviet army will counterattack by 3 front armies, totaling 15 group armies. December 6 was the turning point in the Soviet-German battlefield. On the front line hundreds of kilometers around Moscow, Zhukov commanded the counterattack troops to attack across the board. A large number of new Soviet troops, later called "Siberians" by the Germans, suddenly appeared on the battlefield. The "Siberian" wore thick winter clothes. The weapons are well-equipped and adapted to deep snow operations. They swept over with tiger vitality. The German line of defense was constantly being broken through, and with local breakthroughs, the entire line of defense began to waver. Finally, the Germans retreated. The German army had been invincible for more than two years, and this was the first time that it had retreated in large strides in the face of a superior opponent. The German retreat lasted for more than two months. During this period, Hitler kept losing his temper and ordering: No retreat! The German generals on the Eastern Front were very puzzled. In the severe cold of minus 30 degrees and under the strong offensive of the Soviet Army, the only way to preserve the troops was to withdraw. Why did Hitler repeatedly refuse to allow retreat? But as posterity has pointed out, Hitler was right. If he allowed the retreat, there would be the same situation as Napoleon's army. The troops would be scattered due to the retreat, and the troops that were out of control would walk through the snowy Russian wilderness in twos and threes. Since it was impossible to organize a defense line, they would have to be buried in the wind and snow...
