The ship was linking up with a X-wing flight group based out of the Ottegan system when Captain Tekba received word from General Lando Calrissian that it was going to be hit by a missile, shot from Emperor Palpatine's Galaxy Gun.
When Tekba brought up that the craft couldn't escape in time, Calrissian urged him to attempt to destroy it. Despite its fighters and defensive guns putting up a valiant effort, the missile still hit Pelagia and destroyed the vessel, along with its crew and passengers. It was another triumph of Palpatine, who had already destroyed at least one troopship before her.
