Book IX
The life-and-death struggle against France begins, with Napoleon depicted as a glory-seeking fool. Andrey turns away from his past and commits himself to the men in his regiment, who adore him. Nikolay refrains from killing a Frenchman and is decorated for bravery because he took a prisoner. Natasha slowly recovers, aided by religious faith. Petya joins the army out of a youthful patriotism which Pierre also shares. The Russians respond massively to the national threat, and Pierre feels within him an"ultimate mission" involving his love, the comet, Napoleon, and the war itself.
Book X
The French who are penetrating Russia march toward their doom in the"irresistible tide" of destiny. The old prince dies and Marya moves her household to Moscow, but the war looms closer. Despite the national upheaval, the Petersburg salons remain the same. Marya and Nikolay have a romantic first meeting, while Pierre visits the deathmarked Andrey on the eve of Borodino. The battle is described as a death duel, with the Russians winning morally, if not physically. This marks the turning point from defeat to victory for Russia.
Book XI
Tolstoy discusses mass activity as a combination of"infinitesimal units of activity" and provides a short summary of past and future events. Moscow's abandonment and burning is the great deed that saves Russia and the moment-by-moment details of the event are discussed, including Rastoptchin's last-minute bid for glory at the expense of the cause he pretends to further. The Rostovs leave Moscow, their caravan including the mortally wounded Prince Andrey. He is reunited with Natasha, who nurses him. So close to death, Andrey understands the quality of divine love. Truth results from a life-death confrontation. Pierre conceives the plan to assassinate Napoleon, but other incidents show he is destined to fail.
Book XII
Nikolay and Marya meet again in the provinces, and Marya travels to see her brother. She and Natasha are with him when he dies. Pierre is nearly executed by the French, who accuse him of incendiarism. He experiences a"rebirth" in prison through Karataev, an almost mythic figure symbolizing the unity of love and hate, life and death.
