Star Wars #1 by Jason Aaron

Set shortly after the Death Star's destruction, the Rebels infiltrate an Imperial weapons factory on Cymoon 1 by posing as Jabba's envoys. When Darth Vader arrives, Chewbacca's assassination attempt fails, Luke recklessly confronts him with a familiar lightsaber, and Han hijacks an AT-AT to cover the sabotage. With alarms blaring and scavengers stripping their ship, the mission devolves into a frantic escape that ends on a cliffhanger.
