Battle of Gall ( Clone Wars ) A battle was fought in 22 BBY on the moon of Gall during the Clone Wars between the Galactic Republic and the Confederacy of Independent Systems . The Separatists invaded the moon in C - 9979 landing craft protected by an experimental Geonosian shield technology , which prevented the Confederate vessels from taking any damage from Gall defenders ' blaster fire . However , Jedi Knight Anakin Skywalker and his Padawan Ahsoka Tano , who were on the moon at the time of the attack , managed to infiltrate the lead craft that was projecting the shield and destroyed it with explosive charges from within , leaving the planetary defenses to destroy the rest of the invasion force . The battle . In 22 BBY during the Clone Wars , the Confederacy of Independent Systems attacked the gas giant Zhar ' s moon of Gall with a force of Vulture droid starfighters , 2 C - 9979 landing craft and a lead landing craft , which was equipped with an experimental deflector shield of Geonosian origin . The shield extended itself onto the entire Confederate force and allowed the Separatist forces to shoot through it while at the same time protecting them from enemy fire . Gall planetary force under the command of a sergeant engaged the enemy , attacking with artillery and starfighters , but were not able to penetrate the shield . At the time of the attack , Jedi Knight Anakin Skywalker and his Padawan Ahsoka Tano were stationed on the moon . After being informed by the sergeant of the shield ' s capabilities , Skywalker came up with a plan to lower it . Taking a pack of explosive charges , Skywalker and his Padawan piloted two jet - wing s , which were normally used for spraying fertilizers , and used them to reach the lead landing craft . The jet - wings were not detected by the ship ' s sensors , and the two Jedi were able to land on its hull . They managed to infiltrate the craft , although the jet - wings were destroyed by enemy fire in the process . Inside , they found stacks of deactivated battle droids , but Skywalker considered them not to be a threat , since he believed that all energy had been diverted to the shield . Skywalker and Tano reached the controls of the shield and started planting explosives . Once the explosives were set and the five - minute countdown began , an intruder alert was sounded and the Jedi were attacked by a large number of B1 battle droids , B2 super battle droids and B2 - HA series super battle droid s . Hoping to escape from the vessel , Skywalker and Tano tried to reach the airlock , but were overwhelmed by droids . As the countdown to the explosion continued , they took a defensive stance and fought for their lives against the Separatist forces , until Skywalker concentrated on coming up with an escape plan and remembered the behavior of womp rats from his native planet of Tatooine ; when in danger , the womp rats burrowed into the sand . Following the womp rats ' example , Skywalker used his lightsaber to cut a hole in the ship ' s floor , and he jumped into the hole with Tano right before the landing craft exploded . The Jedi used the Force to slow their descent and landed on top of their Delta - 7B " Aethersprite " - class light interceptors , which had just been refueled and piloted there by Skywalker ' s astromech droid , R2 - D2 . With the lead landing craft destroyed , the shield was gone , and Skywalker was assured that the planetary defense force would be able to repel the rest of the invasion force . Behind the scenes . This battle was featured in " Inside Job " , a short comic published the UK - exclusive magazine " " in December of 2009 .
