Princess Leia is one of the main characters of the first Star Wars trilogy that we also find in the third trilogy. She is one of the main commanders of the rebel alliance challenging the evil galactic empire. In the first episode, she was taken prisoner by the terrible Darth Vader and sent a message via the robot R2D2. She manages to escape thanks to Luke Skywalker and Han Solo who intercepted the robot’s message and they join the rebel alliance. In the second film, The Empire Strikes Back, the alliance set up shop at the Echo base on the icy planet Hoth thinking that they would never be found by the Empire on that planet. But they are detected and attack the base. They try to defend themselves but are finally forced to flee.
