Second ambush in the Graveyard A battle in the Graveyard was the result of an ambush mounted by Ysanne Isard against Rogue Squadron during the Bacta War . Background . After the successful strike at Qretu 5 , Rogue Squadron launched a hit - and - fade campaign against the Thyferrans bacta shipments . In each attack , the Rogues showed up only for the time needed to force the Star Destroyers to scramble their fighters , launch some proton torpedoes to take out a few TIEs and then scatter . As this tactic was costing the Bacta Cartel in both credits and prestige , Ysanne Isard attempted to mount an ambush against the Rogues . Thanks to Fliry Vorru , Isard was able to locate the rendezvous point in the Alderaan system where the Rogues were to receive a big shipment of munitions and spare parts from Talon Karrde ' s group . An Interdictor cruiser leased by High Admiral Treuten Teradoc would insure that the Rogues would not be able to escape from the battle zone . The battle . The Graveyard was the place chosen for the rendezvous between the twelve freighters led by " Pulsar Skate " and escorted by Rogue Squadron and its allies and Karrde ' s half - dozen ships led by Quelev Tapper on the " Starry Ice " . As the two groups were beginning the transfer operation , the Interdictor cruiser " Aggregator " and the " Victory II " - class Star Destroyer " Corrupter " left their concealed position . The " Corrupter " positioned itself between the Interdictor and the Rebel snubfighter s , begun to launch its starfighters and opened fire against the freighters . Wedge Antilles led the Rogues in the first run of against the " Corrupter " , while Tal ' dira ' s squadron covered them from the TIE starfighters . The proton torpedoes volley collapsed the ship ' s port shield and some of the torpedoes hit the destroyer ' s hull , blasting apart armor plates and crushing turbolaser batteries . To protect its unshielded flank , the ship rotated on itself to present the starboard shields to the attackers . While Tycho Celchu was nearing to order the launch the second volley , the " Valiant " , a " Thranta " - class War Cruiser , ranged up from the Graveyard and opened fire against the unshielded flank of the " Corrupter " . The second proton torpedoes volley then arrived adding , up its damage to the doomed ship . Wedge Antilles waited to launch his second pair of proton torpedoes until he was able to target the bridge of the ship , and upon impact his torpedos destroyed it . With its bridge gone , the hull of the " Corrupter " was left drifting down into the Graveyard . The " Valiant " then attacked the " Aggregator " ' s starboard shield , while the Rogues launched proton torpedoes against its port shield . With its shield beginning to collpase in several points , the " Aggregator " jumped away without waiting to pick up the surviving TIE fighters and the escape pods launched from the " Corrupter " . Aftermath . After the battle , Tycho Celchu reported to Commander Antilles that the mysterious ship was the " Valiant " , an automated " Thranta " - class War Cruiser originally slaved to the Alderaanian War Frigate " Another Chance " as one of its escort ships . Having lost contact with " Another Chance " , the " Valiant " had returned to the Graveyard and was waiting for the return of its flagship . As the IFF of Captain Celchu was transmitting the " Another Chance ' s " code and his fighter was broadcasting tactical targeting data , the " Valiant " had picked them and joined the fight . Antilles also had Booster Terrik inquire about black market interest in a " slightly used " Interdictor cruiser , so as to give High Admiral Teradoc the implication that Rogue Squadron would attempt to capture his cruisers if he leased them to Isard again .
