Battle of Kalandis Seven During the Galactic War between the Sith Empire and the Galactic Republic , a battle was fought on the planet Kalandis Seven . The Republic Military gained momentum in the conflict after the news of a victory in the Battle of Corellia , and a covert attack on a spaceport and its subsequent bombing were severe blows to the Empire ' s efforts on the planet . The battle also saw Colonel Jace Malcom of the Republic Special Forces Division recalled back to the Core Worlds by Supreme Chancellor Leontyne Saresh , where he would be appointed as Supreme Commander of the Republic Military at some point after the Battle of Ilum . Prelude . Around 3642 BBY , the Galactic War broke out between the Galactic Republic and the Sith Empire after over a decade of peace during the Cold War . The Empire launched an offensive in the Core Worlds as the war continued , invading the planet Corellia and sparking the lengthy Battle of Corellia . The Empire also attacked planets across the Inner Rim and the Mid Rim , including Kalandis Seven in 3641 BBY . The battle . The Imperial Navy deployed command ships around the planet , though the Republic Military was still able to gain a foothold on the surface as the Republic Navy engaged the Imperial ships . Agents of the Republic Strategic Information Service aboard the ships began to propaganda down to the surface after the Battle of Corellia ended in a resounding victory for the Republic . The loss at Corellia forced the Empire to abandon its Coreward offensive , and Supreme Chancellor Leontyne Saresh ' s victory speeches were used to inspire the fighters on Kalandis as they continued to fight amid Kalandis VII ' s fog - covered canyons and plains . During the battle , a squad under the command of Sergeant Shanra Immel was tasked with destroying a nearby spaceport that was under Imperial control . Colonel Jace Malcom of the Republic Special Forces Division was assigned in an advisory capacity to the unit , though the group was attacked on the way to their objective and Corporal Amden vor Keioidian was critically injured . Immel decided to leave Keioidian behind with his med tracer active in hopes that he would be rescued , despite the possibility that the Empire might deploy the troopers known as " vultures " that hunted injured enemy combatants via their tracers , and the unit continued on to their objective . They reached their target three hours later , and the unit prepared to plant beacons on the spaceport so that the Republic ' s fighter wings could target the base accurately — a plan put together by Colonel Malcom . The attack was a success , as the Republic soldiers quickly eliminated the few sentries and personnel in their path in the south side of the spaceport and planted their beacons . However , Colonel Malcom spotted a planetary command ship that had just landed , and he decided to board the ship himself while Sergeant Immel ' s squad retreated and waited for the Republic fighters to arrive . Three hours later , Malcom began his attack aboard the ship , and he made his way to the bridge after eliminating the few sentries who made the mistake of crossing his path . Ignoring the scattered officers who were manning the ship ' s controls , Malcom charged the Sith overseer who was in command of the vessel . The resulting brawl caught the Sith by surprise so that she could not use her lightsaber , though she was still able to unleash a blast of lightning at the soldier before Malcom unloaded his blaster rifle into her stomach . To Malcom ' s surprise , the officers fled the bridge after realizing that the Sith had activated the ship ' s self - destruct mechanism , and the soldier fell through the viewport of the cruiser as it tore itself apart . However , Malcom landed on the wing of a Republic fighter , saving him from falling to his death , and the colonel was taken to a nearby base where he boarded a shuttle to the starship " Frontier Justice " . The " Justice " and its Jedi Knight pilot had been sent by the Supreme Chancellor herself , as Malcom was being recalled to the Core Worlds , though Malcom did not expect Sergeant Immel and her squad to survive longer than a month . Aftermath . Not long after the battle , Malcom was selected to replace Supreme Commander Rans by the Supreme Chancellor , and the Special Forces veteran continued to guide the Republic Military during the ongoing war with the Empire . Behind the scenes . The battle of Kalandis Seven first appeared in " The Last Battle of Colonel Jace Malcom " , a short story written by Alexander Freed for " Star Wars Insider 137 " in 2012 . The story depicts Malcom ' s last assignment before being recalled to the Core Worlds , where he will be appointed as Supreme Commander at some point after the Battle of Ilum .
