The conflict known as the Fourth Battle of Qotile unfolded during the Stark Hyperspace War. This was the fourth engagement out of five that occurred on Troiken, a planet situated in the Outer Rim. Despite the Stark Combine's initial strategy of besieging Mount Avos, Iaco Stark opted for an offensive maneuver. This decision was influenced by the escape of multiple senators along with a Jedi Master to Coruscant, coupled with the revelation of a concealed entry point into the Avos mine. The troops under Ranulph Tarkin's paramilitary were facing shortages of bacta, provisions, and munitions. However, with the assistance of Billibango, a Xexto native possessing detailed knowledge of the mine's layout, the Republic forces successfully defended against the assault.
This victory for the Republic enabled the Jedi to communicate with the Jedi Council located on Coruscant, thereby facilitating the formulation of a strategy for the final battle. Concurrently, Stark's repeated failure to overcome the Republic's military nearly resulted in his demise at the hands of the Combine's co-directors.
