The Empire launched an assault on the small transport vessel, the Tantive IV. It has been boarded and fully sweeped over by the 501st, as well as Lord Vader himself. The information they were looking for was nowhere to be found, however they have successfully captured Leia Organa.
The other surviving Rebels of the battle managed to overpower their guards on their transport destined to bring them to the prison planet of Kessel and are now continuing their fight against tyranny.
