In 1812 viel het leger van Napoleon Rusland binnen. Koetoezov vroeg Bolkonski om zich bij hem aan te sluiten als stafofficier, maar de prins vroeg om een commando in het veld. Petrus bereidt zich voor op de volgende confrontatie tussen de legers. Tijdens de Slag bij Borodino meldde hij zich vrijwillig aan bij de artillerie. Bolkonsky's eenheid was in reserve, maar hij werd geraakt door een granaat. Anatol en Bolkosnky liepen beiden ernstige verwondingen op. Het Franse leger zegevierde en rukte op naar Moskou.
Nee, helaas is Война и Мир 3: 1812 год nog niet beschikbaar op Netflix in Nederland.
