Balfon was attacked as part of the initial assaults against the Ni'novian Empire. For ten days, the Sith held out under the command of Darth Eroneous, a Sith Adept. Despite many small victories, the Sith were outnumbered, outgunned, and running low on supplies.

The final clash in this battle came when the Galactic Alliance sent a moderately small force to attack the Sith's main army. The Sith managed to drive the Alliance soldiers into a rout and chased them right into an ambush. Eroneous was killed and the Sith army there decimated. The planet surrendered hours after that engagement.
