The Bonadan system was under Imperial control during the early years of Galactic Civil War and thus was the site of a commerce site where several cargo containers were being prepped by a couple of space tugs. A couple of BFF-1 bulk freighters such as Banthar and Deddite were on their way to pick up the containers. However the Rebel Alliance, seeking ways to undermine the Empire's efforts to control star systems, sent two Y-wings to destroy the defenceless cargo area before Imperial military forces could intervene.
The Y-wings wasted no time and attacked the containers, using torpedoes to save time. They also destroyed a Lambda-class shuttle called Krayt that was carrying inspectors. By the time the frigate Enforcer it was too late as significant damage had been afflicted and the Y-wings retreated to Hyperspace.
The successful hit and run mission was recreated as the first training exercise for pilots to use the Y-wing.
