The Empire Strikes Back:

Despite the destruction of the Death Star in the 1976 novel Star Wars: From the Adventures of Luke Skywalker, the Galactic Empire stills retains an iron grip on the galaxy. Upon discovering the Rebel Alliance's secret base, the Empire strikes with massive force, sending the rebels scrambling across the galaxy. Han Solo, Princess Leia, Chewbacca ("Chewie") and C-3PO are slowed down from escaping with the rest of the group by collapsing ice on Hoth. Throughout the story, they remain within The Empire's reach.
