Ambush of Attichitcuk Between 39 BBY and 36 BBY , the Wookiee Attichitcuk was ambushed by B1 battle droids of the Trade Federation on the moon Alaris Prime . The leader of a group of Wookiee colonists who were legally authorized to colonize the moon , Attichitcuk had set out on a scouting expedition with two bowcaster trooper s to investigate the presence of the Trade Federation , a company illegally attempting to take over Alaris Prime . After locating several battle droids the Wookiees headed for a base , but encountered a group of battle droids that attacked the Wookiees after demanding their surrender . The two troopers were killed and Attichitcuk received serious injuries , though the chieftain was quickly rescued by his son Chewbacca and received medical aid . Prelude . Sometime between 39 and 36 BBY , a group of Wookiees led by the Chieftain Attichitcuk were legally authorized to colonize the moon Alaris Prime by the Galactic Senate . The Wookiee colonists , led by Attichitcuk , along with his son Chewbacca and Jedi Master Qui - Gon Jinn , travelled to Alaris Prime and began colonizing the moon . However , the Trade Federation also sought control of the moon to use it as a trade center , and illegally established a competing colony . On Alaris Prime both sides faced attacks by gundarks , a predatory species , prompting the Trade Federation and the Wookiees to send their forces to the gundark nest to eliminate them . The Trade Federation ' s B1 battle droids reached the nest first , and once they had killed all of the gundarks attacked the Wookiee bowcaster trooper s , led by Chewbacca , who fought back and destroyed all of the droids . Following the encounter Attichitcuk began a scouting expedition in the forests of the moon along with two Wookiee troopers to learn more about the Trade Federation ' s activities . Meanwhile at another base Chewbacca and Master Jinn began preparing for any future encounters with the Trade Federation by advancing to a new level of technology and gathering various resources . Attichitcuk caught sight of several battle droids in the area and gave the information on to Jinn before making his way to the base , ahead of his two companions , not realizing a group of seven Trade Federation B1 battle droids blocked his path . The ambush . The battle droids , commanded by DRN - 38 , forced Attichitcuk to stop , and one droid ordered the Wookiee to come with them . The Chieftain refused to comply , prompting the battle droids to fire upon Attichitcuk with blasters . The Wookiee returned fire with his bowcaster , but was severely wounded by the droids and left to die . Once the other Wookiees caught up to Attichitcuk they were both shot and killed . Aftermath . Through the use of the Force , Qui - Gon Jinn sensed that Attichitcuk was still alive , and urged Chewbacca to stay calm . Jinn had the Wookiees construct a medical droid at the bases ' s command center and train at least 10 bowcaster troopers , before sending them and Chewbacca to rescue Attichitcuk . After destroying every battle droid they encountered on the path , the Wookiees reached Attichitcuk and had the medical droid revive the Chieftain before returning to the base with him , encountering and destroying more battle droids on the way . Attichitcuk was still heavily injured , forcing Chewbacca to take his place as the leader of the colonists . With Jinn ' s help the Wookiees planned and executed two major attacks on Trade Federation bases before driving them off the moon in the Battle for Alaris Prime , which Attichitcuk fought in , having made a full recovery . Behind the scenes . The ambush of Attichitcuk was first mentioned in the for the 2001 LucasArts video game " " , before appearing in the game itself and its 2002 expansion " " . The ambush appears in the fourth level of the Wookiee tutorial campaign , " Researching Technology , " as a scripted event that the player is unable to control .
