Battle of Tirahnn ( Clone Wars ) The Battle of Tirahnn was a battle that was fought on the planet Tirahnn during the Clone Wars . Prelude . During the Clone Wars , the Confederacy of Independent Systems captured Tirahnn , a planet that was located on the Perlemian Trade Route , thus disrupting the Galactic Republic ' s vital source of supplies in the region . A few months later , the Republic decided to retake the planet , so they sent a taskforce under the command of Jedi Master Ezar Elasra to recapture the world . The Separatists had sent a fleet to defend the planet , so Elasra realized that a direct attack would result in heavy casualties . He instead came up with an alternative plan , to send a strike team to reactivate a planetary ion cannon that was located on Tirahnn and then launch a surprise attack on the Separatist fleet . With a large proportion of the fleet disabled , Elasra ' s fleet would then enter the system and engage the surviving CIS ships , before launching a ground assault to retake the planet . Elasra summoned a group of Republic agents to his " Venator " - class Star Destroyer , the " Solidarity " , and assigned them the task of reactivating the ion cannon . The agents were to be transported to Tirahnn in a LAAT / s , along with 6 clone troopers and 4 clone commandos . While the agents were reactivating the cannon , which was located in the planets capital city , Tirahnn ; the troopers were to guard the transport ; while the commandos infiltrated and sabotaged the main Separatist base on the planet . Mission to Tirahnn . The troopers , commandos and agents left the rest of the taskforce in the LAAT / s and traveled to Tirahann . The ship passed through the CIS blockade without detection , but due to unforeseen weather patterns , was forced to crash land on the planet . An escaped roggwart , a dangerous creature from the planet Vendaxa , attacked the crash survivors , as it was looking for something to eat . The troopers killed the creature and then hauled its body away and set about disguising the area of the battle and the trail left by the LAAT / s when it crashed . The troops then began preparing themselves for their assignments . The commandos unloaded and assembled their BARC speeder bikes and Commander Husk , the leader of the commandos , gave the agents a holoprojector which contained a map of the surrounding area . He also told the agents that if they set out straight away , they would arrive at the city just before dawn , making it easier for them to avoid the sentries that the CIS had posted there . The clone troopers unloaded as much equipment as they could carry and set off to establish an encampment nearby , where they could remain until the Republic began it ’ s ground assault on Tirahnn . As a final act , one of the commandos rigged the dropship with explosives and blew it up , to prevent the CIS from learning any sensitive information from it . After making their way to the capital city , the agents began to try to locate Commander Zolghast , the commander of the Separatist forces on Tirahnn , as he was the only person who had access to the ion cannon ' s firing codes . They learned the location of the bunker where he was staying and after assaulting the facility , they captured Zolghast and obtained a code cylinder that contained the firing codes . The agents also discovered a secret tunnel that connected the bunker to a secret entrance to the ion cannon . They traveled to the entrance and once inside , attacked a number of battle droids that were defending the facility . Eventually , they found the control center , entered the firing codes and activated the cannon , which started firing on the Separatist fleet , beginning the battle . While the agents had been activating the ion cannon , the commandos had also been largely successful in their mission and had sabotaged the Confederacy ' s vehicle depot . The battle . As soon as the ion cannon began firing , Master Elasra ' s fleet emerged from hyperspace near to the planet , to begin attacking the Separatist fleet . The Confederacy responded by dispatching a team of droids to place explosives on the roof of the ion cannon and destroy it , so the agents went to try to stop them . Republic forces began to land on Tirahnn and encountered light resistance , due the commandos ' sabotage . However , a small force of Separatist tanks had survived and began to make their way through Tirahnn city towards the Republic troops . About 30 minutes after the battle had began , the crew of the " Solidarity " contacted the agents and ordered them to connect the cannon ' s main computer to the Solidarity , so that the weapon could be controlled from the ship . Elasra then spoke to the agents via a hologram and told them that the Separatist tanks were probably going to reach the Republic troops before artillery could be deployed to counter them . He then tasked the agents with placing homing beacons on each tank , so that the Republic fleet could fire on them from space . Elasra also sent a group of clone troopers to collect Zolghast from the agents and transport the commander to the " Solidarity " . The agents ambushed the group of tanks , which was made up of four Ground Armored Tank s , that were defended by battle droids on Single Trooper Aerial Platforms . The attack was a success and the " Solidarity " opened fire on the tanks , destroying them all . The battle began to turn in the favor of the Republic and the clone commandos succeeded in cutting off one of the Separatists ' main lines of retreat . Husk then contacted the agents via comlink and asked them to cut off the Confederacy ' s secondary path by destroying a bridge . Up on the " Solidarity " , Elasra left the ship in an Delta - 7 " Aethersprite " - class light interceptor , to lead a squadron of V - 19 Torrent starfighters in the space battle . However , at the same time , the Confederacy sent the Clawdite spy Braxus Lyn to rescue Zolghast before he could be transported to the " Solidarity " , and then bring him out of the warzone . Lyn disguised herself as Elasra and freed Zolghast , then began to prepare her shuttle so that they could depart the planet . One of the clone commanders began to grow suspicious , as he had participated in the Battle of Brentaal IV , where Jedi Master Quinlan Vos had defected to the Confederacy , so he suspected that Elasra was doing the same thing and sent the agents to stop Zolghast from escaping . Aftermath . The Republic liberated Tirahnn and although they incurred some losses , the battle was largely a success . Elasra thanked the agents for their assistance during the battle . Behind the scenes . The Battle of Tirahnn was created for the Wizards of the Coast source book " Galaxy at War " , where it was the subject of a role - playing scenario titled " Operation First Breach " .
