How did the initial period of the Great Patriotic War end?

If we talk about the first stage of the war of 1941-1945, then the first stage has much in common with the war of 1812. During this period, Soviet troops retreated farther and farther from the attackers inland. At the same time, it was possible to evacuate a fairly large part of the industry. What could not be removed was destroyed. Kharkov and Kiev were mined. Water sources have been poisoned. The authorities of the USSR absolutely did not think about those who were forced to fall into the occupation through the fault of the authorities themselves. There was no transport to transport the civilian population to the rear. The able-bodied population, men, were evacuated. This period ended with the Battle of Stalingrad. As a result of long defensive battles, the USSR was able to seize the initiative and began to attack.
