The Yitabo Mission took place on the world of Yitabo amidst the Galactic Civil War. A number of Wookiees were seized by Imperial slavers. Churhee's Riflemen, having learned of the abduction, acted to free the enslaved Wookiees. Though the Riflemen's "Gunman" was dispatched to gather intelligence, he was taken prisoner by the Imperials. Even with this problem, the Riflemen successfully freed all of the slaves, who then unleashed their fury upon the Imperials who had captured them.
