Hoth
It's a planet. Pretty icy. Rebels were there at one point. Wampa got its arm off, 'cause Luke had to defend himself. Not an ideal situation for either of them. A tauntaun got sliced from groin to neck and was used as a sleeping bag. Luke saw a vision and also Obi-Wan.
There were some shield generators, and a base. Dash Rendar was there, too!
