Mos Eisley Cantina - Tatooine, 1944, Logbook entry:

It's taking shape. Lando is close to a real breakthrough. He is talking to some guy in the Cantina right now, while I am writing that. Earlier he sold slaves to Jabba (ugh..) and did all kinds of so-called chores for him, so obviously he knows a lot about Jabba. Later he managed to get in tight with Lando and Lando managed, that the guy owes him favours. More than just one I can tell.

Mos Eisley Spaceport - Tatooine, 2022, Logbook entry:

The force is with us all. Lando has managed to put a plan together, that could get us into Jabba's palace unseen and get us out in one piece. All we got to do is take the uniform of one of the skiff guards, let Lando put it on and slip him between Jabba croanies, with a commlink, so we can keep contact with him. We're surely NOT gonna send him in the Rancor's nest, without any way to keep contact with us and inform us in case something goes wrong. In Jabba's palace Lando can spy on Jabba and get out stuff we can turn against him. Next will be the droids. I will slip Artoo and Threepio in there, with a message of mine and make it look like I want to give them to him as a present. Then Leia will have her part of the show. We'll disguise her as a bounty-hunter and get her in the palace with Chewie as bait. Chewie is known as Han's companion and therefore has a high price on his head, like Han had. Jabba's doing. Ugh... If we disguise Leia as a bounty-hunter and she takes Chewie to the palace, she will gain Jabba's trust and no one will suspect her. When no one is looking, she will free Han and Chewie, get the droids and then Lando and I will bail them outta this worm din. The perfect plan. It will all go quick and Jabba won't even know anything. Got to stop now. Lando called me. Sounded like something serious!

Mos Eisley Spaceport - Tatooine, 2322, Logbook entry:

This about wraps it up. We are almost ready to get the plan moving. Since we are all together here on Tatooine, the bounty-hunters are getting more gutsy. One of those creeps slipped into our docking bay two hours ago. Boushh was what they called them and I say "was", because Leia and I took him down. That guy tried to capture Chewie and hand him over to Jabba. The oppertunity is somewhat perfect. Now we do not have to worry about Leia's disguise anymore. About mine...well...I got my ways about that.
