Battle of Kalla VII The Battle of Kalla VII took place early in the Galactic Civil War , as part of Operation Skyhook . Prologue . With the Rebel Alliance attempting to find the location of the Death Star , Alliance Intelligence discovered that Imperial ships were using the base near Kalla VII for supplies and repairs on their way to the Death Star . General Jan Dodonna proposed to destroy the Imperial base to strand any passing ships heading for the battlestation , leaving them open to capture . The battle . The plan involved three stages ; destroying the base itself , conducting a raid to remove the escorts of the target ship and leave it defenseless and disabling and capturing the ship itself . First stage . A group of starfighters was assembled for the first stage of the battle , with Keyan Farlander leading three X - wings from Red Squadron to destroy the base . The mission was successful as the Rebels destroyed all supply containers , the defensive minefield and two BFF - 1 bulk freighter s from " Diputs " group . As the Rebels were preparing to leave , the Imperial EF76 Nebulon - B escort frigate " Priam " came out of hyperspace , killing Breth Gart in a freak collision when his fighter hit the ship . Second stage . With the " Priam " now stranded the Rebels prepared to move against it . In order to protect the stranded vessel , the Empire moved quickly to dispatch three CR90 corvettes from " Dar Es " group to protect it and also deployed a minefield around the ship . A " Delta " - class DX - 9 stormtrooper transport was also dispatched to deliver supplies and personnel . The Rebels , meanwhile , prepared an assault to remove these defenses . Two R - 22 Spearheads from Blue Squadron were to engage the " Priam ' s " TIE fighters while two Y - wings from Red Squadron , again led by Farlander , were to destroy the corvettes with their proton torpedoes . All three corvettes were quickly destroyed , as was the incoming transport and the Rebels withdrew leaving only the minefield and a handful of TIEs to defend the " Priam " . One R - 22 was lost during the battle but a subsequent rescue operation retrieved the pilot who had been able to eject . Third stage . With the escort destroyed , General Dodonna gave the order for Alliance Special Forces to conduct a " board and capture " operation against the " Priam " . The Rebels sent a complete squadron of Y - Wings from Gold Squadron to disable the " Priam " , attacking in two groups of six . Keyan Farlander , having just returned to the Mon Calamari Star Cruiser " Independence " from the previous mission , immediately launched to support the operation , flying the only craft available , an R - 22 Spearhead . Farlander moved quickly to destroy the few remaining TIE / LN starfighter s before they could pose a threat to the Y - wings and then proceeded to destroy the minefield while the Y - wings used their ion cannons to disable the " Priam " . The " Priam " made one last attempt to fight back , launching two TIE / sa bombers but they too were quickly destroyed . After losing many Y - Wings , the " Priam " was finally disabled . The Y - wings withdrew while the Special Forces team moved in with transports from " Assault " group carrying commandos to board the frigate . Once captured , " Lambda " - class shuttles from " Panda " group delivered the new crew for the ship while transport group " Jordi " delivered supplies . Once all the transports were aboard , the Rebel forces , along with the newly captured frigate , jumped to hyperspace . Aftermath . Despite Farlander having not been scheduled to fly in the final part of the battle , Commander Lagrane acknowledged during his debriefing that his actions had helped keep Rebel losses lower than expected . Examining the frigate ' s database , the Alliance learned that the Death Star was located above Despayre . Corvette group " Ethar " was dispatched to the Horuz system to investigate .
