War and Peace, Part IV: Pierre Bezukhov.

As Moscow is set ablaze by the retreating Russians, the Rostovs flee their estate, taking wounded soldiers with them, and unbeknownst to them, also Andrei. Pierre, dressed as a peasant, tries to assassinate Napoleon but is taken prisoner. As the French are forced to retreat, he's marched for months with the Grande Armée, until being freed by a raiding party. Part four of the four-part adaptation of Leo Tolstoy's 1869 novel.
