18 12 Napoleon invaded Moscow in the French-Russian War. Why did Kutsov, commander-in-chief of the Russian army, advocate withdrawing from Moscow to Kaluga in the southwest of Moscow?

Because at that time, the French Lien Chan won the victory, the Russian army suffered heavy losses, the momentum was in full swing, and the morale was unprecedented. In order to avoid the sharp edge of the French army, Kutuzov, who was in no hurry to fail, advocated withdrawing from Moscow. However, because of this incident, the masses and the country are not satisfied. On August 20, Kutuzov was replaced as commander-in-chief of the Russian army. In less than a week, he fought a bloody battle with the French army in Borodino, with heavy casualties on both sides. Subsequently, Russian troops voluntarily withdrew from Moscow and moved to Kaluga, threatening the French army's traffic lines, and organizing the military and civilians to "clear the field", harassing the hungry and cold French army, so they had to withdraw from Moscow and retreat along the south. The Russian army turned to counterattack and pursued a large number of French troops. The French army lost all the cavalry and almost all the artillery, leaving only 30 thousand people to withdraw from the country. So Kutuzov's order to retreat can be said to be a feasible truth, but he did not take into account the domestic situation at that time, so it can only be said to be a pity.
