The Government Tree and nearby Kepitenochan were quickly devastated . Thousands of Wookiees were captured or killed within the first few days . In desperation , Attichitcuk contacted his son Chewbacca , who was unable to convince the Rebel Alliance to send assistance eight months after the Battle of Endor . The Alliance was busy fighting the Empire and warlords at the time , including a battle at Glom Tho . Battle . Setbacks . Han Solo and Chewbacca , arriving on Kashyyyk , attacked several groups of Trandoshans and freed a group of Wookiees that retook Kepitenochan , only to find the city heavily damaged and only one survivor : Weebacca . Together , they rebuilt the Government Tree and guarded it against multiple Imperial attacks . In doing so , the Wookiees reunited under the monument . However , they still could not contact the Alliance with signal jammers blocking their transmissions . Betraying the Wookiee resistance , Weebacca told Solo and Chewbacca that the communications jammers were in Okikuti . Upon entering the city , they realized it was a trap , as Darcc ' s forces advanced on the Okikuti ' s gates while there was no exit . They cut through the trees to the nearby river and built sea ships to escape to Chenachochan . Destroying several Imperial sea frigates , they stole Imperial walkers from Tunnatutikan and met up with Shoran . Together , they destroyed the signal jammers with the help of Imperial equipment captured from the Imperial Depot and four Cruisers . They were then able to send a transmission to the Rebel Alliance , which was received by Lando Calrissian . Liberation . Liberating the rest of Chenachochan , the Wookiees captured an Imperial airbase and gained the support of the Ittummi Berserker s . Darcc ' s palace was destroyed by the united Wookiee Army and the traitor Weebacca was killed by Chewbacca . However , Darcc and Pekt escaped in a " Lambda " - class shuttle full of Wookiee prisoners . Battle of the Avatar Orbital Platform . The Wookiees , led by Chewbacca and Solo , flew to the Avatar Orbital Platform and with the help of Rogue Squadron , Luke Skywalker and Lando Calrissian in the " Millennium Falcon " , they rescued Attichitcuk with the Wookiee captives , killed Moff Darcc and the Trandoshan slaver Pekt , and finally , blew the main reactor of the facility . The New Republic Third Battle Group also fought in the battle under the command of Admiral Gial Ackbar . The fleet left from Bothan space and fought Grand Admiral Peccati Syn . Bothan agents sabotaged two of Syn ' s Interdictor cruisers . The agents also impersonated aids of Admiral Treuten Teradoc , who promised reinforcements to Syn from the Greater Plooriod sector . Ackbar ' s " Home One " and Captain Verrack ' s " Maria " caught Syn ' s flagship , the " Silooth " in a crossfire and destroyed its bridge in a proton torpedo barrage . Syn was killed when his ship was vaporized due to his underestimating Ackbar ' s tactics . Aftermath . Following Kashyyyk ' s liberation , the Imperials abandoned the spice planet Kessel . Chewbacca , Solo , Skywalker , and Calrissian agreed to go there and rescue all the slaves there .
