Theft of the Death Star plans

During the Galactic Civil War, the Alliance to Restore the Republic mounted a successful theft of the plans to the Death Star, the Galactic Empire's deep space mobile battle station. In doing so, the Rebels scored their first major victory against the Empire. After the battle, the plans were transmitted to Princess Leia Organa of Alderaan aboard the Tantive IV. The Empire pursued the Rebels to Tatooine, where they waged a battle to recover the plans. Organa was captured, but the Death Star plans made their way into the hands of the Rebellion. This led to the Battle of Yavin in which the Rebels found a weakness in the Death Star and destroyed the station.
