Drop Cargo
The reason Han got in trouble with Jabba in the first place is because of a previous run-in with the Imperials. He was on a smuggling run for the sluglike gangster, and when he saw some Imperial ships coming his way, he ditched his stolen cargo and hightailed it into hyperspace. This offscreen moment of cowardice before A New Hope begins turns out to have serious, far-reaching repercussions, affecting events even as far as Return of the Jedi.
