The humanitarian effort to Langston represents an operation undertaken by both the Galactic Republic and the Jedi Order to provide aid to the people of the planet Langston. This assistance followed an attack launched by the Confederacy of Independent Systems at the beginning of the Clone Wars, an assault that the Grand Army of the Republic successfully defended against. Spearheading this mission were the recently elevated Jedi Knights Anakin Skywalker and D'urban Wen-Hurd, supported by the 302nd Battalion consisting of clone troopers. Furthermore, as part of a program initiated by Republic Supreme Chancellor Sheev Palpatine to acclimate younglings and Padawans to the presence of clones, five Jedi younglings were included in the expedition. Skywalker, along with Initiate Mill Alibeth, and the astromech droid R2-D2, abruptly left the mission upon Skywalker's discovery that his previous Jedi Master, Obi-Wan Kenobi, faced imminent peril on Cato Neimoidia.
