Following the battle that triggered the Clone Wars in 22 BBY, Bacara fought alongside several Jedi, including Jedi Master and Council member Ki-Adi-Mundi.
Bacara was given command of the Galactic Marines, which was attached to the 4th Sector Army. At some point, the Clone Commander learned space and land-based fighting. CC-1138, nicknamed 'Bacara,' was a clone trooper commander who served in the Grand Army of the Republic. Cloned on the planet Kamino, Bacara received initial training from the former Concord DawnJourneyman Protector Cort Davin, who taught the young clone the ideals and traditions of the Journeyman Protectors.
