Why did Germany fail to capture Moscow during World War II?

First of all, the production capacity of German tanks is limited. Germany produced only 56,000 tanks in the four or five years from 1936. If there were 20,000 tanks, guderian wouldn't have to support the north and south everywhere. Germany could have attacked Moscow in August 194 1.

Second, the Soviet Union's traffic is relatively backward, with few roads and railways, and roads are still dirt roads, which brings inconvenience to German supply. If Germany has railway troops, highway troops and roads are built quickly, it can also reach Moscow in September.

Third, the supply of German troops is insufficient. Germany sent troops 1 13 divisions, with less than 2.5 million people. After three months of fighting, it should rest and replenish its troops. Soldiers who have been sick, tired and injured for three months should change shifts. It took Germany half a year to add hundreds of thousands of people, and the number was insufficient.

Fourth, the United States and Britain have greatly increased their strength in aiding the Soviet Union. Only when the United States and Britain helped to eat food and meat, guns, planes, tanks, bullets and shells, machine tools and metal parts of military factories, and trucks carrying soldiers, did the United States and Britain help the Soviet Union to have the strength to fight.

Fifth, the Soviet bureaucratic government strictly controlled its citizens, mobilized millions and tens of millions of people to join the army, and one batch of cannon fodder fell down to supplement another. The Germans defeated millions of Soviets, millions of Soviets, but the losses of the Germans could not be made up, and the Soviets soon made up for them.
