As to the specific events after Jedi, our heroes spend the night on Endor as the Rebel fleet protect the Ewoks from Death Star debris. Leia senses Luke is in turmoil and leaves Han Solo and the village early the next morning to find Luke and R2 miles away prepping the Imperial shuttle for liftoff. He says that he senses impending danger, though Leia states that there is no way that Imperial reinforcements could arrive so soon. Luke says that he was no match for the Emperor, and that his victory was actually a failure. He is going into exile to become a master, like Yoda.

It is then that the Imperial fleet attacks the planet, and the damaged Rebel fleet is no match for the Imperial forces. The capital ships are shot down, and the Ewok village is bombarded from space. Han Solo, Chewbacca, and Lando are killed in the bombardment, never having gotten to their ship, as is C-3PO (Han Solo never actually saw the Falcon again after his fateful statement before the battle). Luke, Leia, and R2 barely escape the destruction with their lives.

Leia is carrying the child of Han Solo, conceived in the first hours of Rebel Victory before his tragic death. Luke vows to rebuild the Jedi order and train Leia in the ways of the Force.
