who defeated obi-wan kenobi in a lightsaber duel
Obi-Wan Kenobi In the spaceport city Mos Eisley, Obi-Wan uses the Force to trick Imperial troops into letting them through a military checkpoint. They enter a local cantina and make a deal with two smugglers, Han Solo and Chewbacca, to fly them to Alderaan aboard their ship, the Millennium Falcon. During the journey, Obi-Wan begins instructing Luke in lightsaber combat. He suddenly becomes weak and tells Luke of "a great disturbance in the Force". Emerging from hyperspace, the party finds that Alderaan has been destroyed by the Empire, and the Falcon is attacked by an Imperial TIE Fighter. The trio chase the TIE fighter to the Death Star, and subsequently get caught in the space station's tractor beam. On board the Death Star, Obi-Wan shuts down the tractor beam, but Darth Vader confronts him and they engage in a lightsaber duel. Obi-Wan uses the duel to distract Vader as Luke, Leia, Han and Chewbacca escape to the Falcon. Although Vader strikes Obi-Wan down, his body mysteriously vanishes the moment he dies. At the climax of the film during the Rebel attack on the Death Star, Obi-Wan speaks to Luke through the Force to help him destroy the Imperial station.
