Russia defeated Napoleon by starving and freezing his army to death. During the invasion, French troops were forced to march through miles of snow in extremely cold weather, without the proper clothing and supplies to survive it. The Russians purposefully burned down their own villages so that the French could not raid them for supplies. By the time Napoleon reached Moscow, his army's morale was extremely low and he had sustained heavy losses, and he was forced to retreat soon afterward. Russia's cold weather that makes it almost impossible to invade is often called 'Russian Winter' or 'General Winter'.
