Petrakis was the site of the first engagement between Rebel Alliance B-wing starfighters and Imperial forces. During an attack on an imperial convoy that carried a squadron of Fighters, the escorting TIEs were so panicked when they first encountered the attacking B-Wings that they left formation and fled. So the rebel starfighters managed to destroy the whole convoy consisting of several Freighters, Transports and Shuttlecraft despite the arrival of imperial reinforcements, a full wing of assault gunboats.
