The planet nearly fell to the cult's onslaught. The Galactic Republic requested the Jedi Order intervene in the attack, and a task force was sent to the planet. The force took several casualties, but eventually forced the Bando Gora off the planet.
During the battle, the Bando Gora took Komari Vosa and two other Jedi as prisoners-of-war and held them hostage in their castle on Kohlma. Vosa and the Jedi were brutally tortured, and she eventually fell to the dark side of the Force, becoming the leader of the Bando Gora after escaping her prison and killing two fellow prisoners.
Vosa's eventual dark-side leadership, combined with Qui-Gon Jinn's rogue-Jedi reputation that would end in his murder by a Sith Lord, would serve as the culminating impetus for Count Dooku's departure from the Jedi Order.
The Battle of Baltizaar was originally placed in 39 BBY by Jedi vs. Sith: The Essential Guide to the Force. However, the more recent Darth Plagueis novel places the battle in 33 BBY, shortly before Darth Maul's assignment to Dorvalla.
